Are we ready for the library of the future
A. Librarians today will tell you their job is not so much to take care of books but to give people access to information in all forms. Since librarians, like so many people, believe that the entire universe of commerce, communication and information is moving to digital form, they are on a reform to give people access to the Internet—to prevent them from becoming second-class citizens in an all-digital world. Something funny happened on the road to the digital library of the future, though. Far from becoming keepers of the keys to the Grand Database of Universal Knowledge, today"s librarians are increasingly finding themselves in an unexpected, overloaded role: They have become the general public"s last-resort providers of tech support.
B. It wasn"t supposed to be this way. Today"s libraries offer a variety of media and social-cultural events—they are "blended libraries," to use a term created by Kathleen Imhoff, assistant director of the Broward County Library of Fort Lauderdale, Florida. At the newly remodeled San Francisco Public Library, the computers are prominently displayed in the center of the library building while the books are all but hidden on the periphery (外围). Imhoff"s own library has word processing and other types of software for visitors to use, Internet access, audio CDs, videotapes, concerts, lectures, books and periodicals in three forms (print, microfiche and digital). Many libraries have found that this kind of "blending" is hugely popular in their communities, and librarians explain the changes in their institutions" roles by pointing to the public demand for these new services. But other trends are at work, too.
C. For some time, libraries have been automating their back-end, behind-the-desk functions for reasons of cost and convenience, just like any other business. Now, the computers have moved out from behind librarians" desks and onto the floor where the visitors are. This means that, suddenly, library-goers will have to know how to use those computers. This sounds reasonable enough until you take a close look. Unfortunately, the same technology that cuts costs and relieves librarians of work behind the scenes increases it for the public—and for the librarians at the front desk who have to help the public figure out how to use the technology. The unhappy result: People are simply not finding the information they seek.
D. If you are just coming to the library to read a book for pleasure and you know what a card catalog is and you have some basic computer skills, then you are going to be OK. But if you are trying to find some specific information—say, whether software in the classroom helps kids learn better or the causes of lung cancer or the basic procedure for doing a cost-benefit analysis of computer systems (three topics I have actually tried to look up in the San Francisco library)—then you"re in trouble.
E. To begin with, library visitors must now be able to type, to use a mouse and a menu and to understand the various types of computer interfaces (terminal text, windows and browsers). It"s also nice if you know 17 different ways to quit a program, which electronic databases you should look in for what kinds of information, the grammar necessary to define your search and the Library of Congress" controlled vocabulary. After I had been to the new San Francisco library three times, I started keeping a folder of instructions on how to do a keyword search, since I would forget between visits.
F. Probably 50% of the population has never used a computer, fewer know how to type and almost nobody knows anything about electronic databases or searching grammar. As a result, the public library is now engaged in a massive attempt to teach computer literacy to the entire country. Some librarians compare it to the adult literacy programs the library also sponsors, but this is on a far larger scale—and less closely tied to the library"s traditional mission. The response at each library system has been different. Some libraries actually give courses in word processing, accounting program and so on. But even at libraries where the staff has resisted becoming computer trainers, they are still forced to devote significant resources to the problem.
G. Such has been the case in San Francisco, where people with disabilities can sign up to use the voice-recognition program Dragon Dictate—but only if they can prove they already know how to use the software. The librarians have neither the time nor the peculiar skill (nor the time to develop the skill) to teach it to them. At the reference desks, librarians try not to spend a lot of time teaching people the basics of how to use the computer, but sometimes it"s unavoidable. "We try to get them started," says business librarian John Kenney. "We let them do as much as they can on their own and they come get us. It"s certainly a big problem."
H. The San Francisco library offers classes on its own electronic catalog, commercial periodical indexes and the Internet twice a week as well as occasional lectures about the Internet. Although it seems odd to me that people now need to take a two-hour class before they can use the library, the classes are always full. But despite the excellent teachers, two hours is simply not enough to meet the needs of the students, many of whom have never used a computer before in their lives and many of whom simply can"t type. When I took the class one Tuesday, the man sitting next to me said he has used the library"s computer catalog many times, but he keeps making typing mistakes without knowing it. This unexpectedly throws him into the wrong screens and he doesn"t know how to get back. On the floor, he repeatedly has to ask a librarian for help.
I. "Providing technology does not mean people can use the technology," says Marc Webb, a San Francisco librarian and one of the teachers. "Half the voters are still trying to read English." The library has also had to deal with the practical difficulties of making its catalog accessible via the Internet, a new service many libraries are starting to offer. "It"s absolutely overwhelming," Webb says. "Everyone is getting to us with multiple transports, they"re all using different software, they have Winsock or Telnet set up differently, and suddenly the library is forced to become a hardware and software help desk. When you"re trying to tell someone over the telephone how to set up Winsock through AOL when this is the first time they"ve ever used a computer, it"s very difficult."Computers are more prominently displayed than books in San Francisco Public Library.

Here comes the e-book revolution
A. At what temperature do electronic books catch fire We"re going to find out sometime this year. E-book sales are about to ignite. On Monday, Amazon.com is expected to unveil a new version of its Kindle reader. It will probably be a lot better and a little cheaper than the first version. But the real news already broke this week: A company spokesman announced that Amazon plans to offer Kindle books on Ceil Phones. This news countered Google"s announcement that the 1.5 million public domain books available on its Google Book Search offering will soon be available (free, of course) via a new Cell Phone application.
B. I believe that Cell Phones will quickly outpace the dedicated e-book readers, including the Kindle, as the platform of choice for e-book readers. Leading the pack The iPhone, ironically. It"s worth noting that Amazon.com sold more Kindles (at least 500,000) in its first year of sales than Apple sold iPods in its first year (378,000). Apple may not understand the value of e-books, but iPhone users will embrace them anyway. The reason is simple: The iPhone has a huge, high-quality screen. And its user base includes millions of people who love to do everything on their iPhones, including reading, which they"re already doing with online content. I (and others) have been predicting for some time that Apple will ship a killer tablet at some point. This device, I believe, will have the iPhone user interface and a super high-quality screen. It will be ideal for reading e-books as well.
C. Just because e-books are available on better (the new Kindle) and more (all Cell Phones) devices doesn"t mean people will read them. But mark my words, read them they will. Six trends will conspire (共同促成) over the next year to drive e-book reading to levels that will surprise just about everybody.
D. The economy is in the tank, and people are looking to cut costs any way they can. An Amazon Kindle pays for itself after the purchase of 20 or 30 books, then starts paying dividends. You save big on books, magazines and newspapers. These savings will grow even more attractive as the recession deepens.
E. Interest in protecting the environment just keeps growing and growing. The idea of getting a daily newspaper or a weekly or monthly magazine on paper seems incredibly wasteful to the point of decadence. Environmental consciousness will drive e-book acceptance.
F. The book publishing industry is one of the most backward, musty, out-of-date businesses in our economy. While every other kind of information moves at the speed of light, the process of publishing a book is like something from the Middle Ages. For authors, it can take months to even find a literary agent willing to represent their work. Then the agent takes months to find a publisher. Then it takes ages for the publishing company to get the book out there. People are already circumventing (设法回避) all this by self-publishing. The self-publishing industry is the only area of paper-book publishing that"s thriving right now. Soon enough, a huge number of authors are finally going to get fed up with the publishing industry and just self-publish electronically. They"ll hire their own freelance editors, and do the marketing themselves. The publication of a finished manuscript will take minutes, rather than months.
G. Old-school thinkers in the publishing industry will lament (悲叹) the slap-dash nature of self-published e-books, and sniff" that books are no longer published with the quality and care that they used to. (Never mind that book publishers abandoned high standards years ago in previous cost-cutting initiatives.) The world will pass them by as the book industry undergoes the same transition that happened with the media and blogs. First, the media didn"t understand blogs. Then they invalidated them. Then they accepted them. And now blogs are where the credibility is. Every columnist and reporter has a blog, and now major TV news programs are built around the opinions of bloggers. A similar transformation will take place about the credibility of serf-published and electronic books.
H. Like the move from silent pictures to "talkies," the transition to electronic publishing will prove fatal to laggards. Those aggressively pursuing and developing e-books will rise to take control of the publishing industry. Part of this revolution will happen in e-book marketing. The new generation of e-book publishers will leverage social media, contextual advertising and other innovations. For anyone who spends time online, specific e-book titles will increasingly be advertised and marketed and integrated into other content. E-books, now mostly invisible, will soon be everywhere.
I. The shift from print to electronic will change the nature of the book itself. Many books will be shorter. They"ll be more timely and culturally relevant. They"ll be more colorfully and engagingly written. And they"ll go after young readers like nothing before. As in Japan, this will spark a new cultural phenomenon of young people not just reading, but also writing novels and other book types on their mobile devices. The idea that "people don"t read anymore," especially young people, will be revealed as false. Young people today read more, and write a lot more, than any generation in history. To date, they"ve been unexcited about books, magazines and newspapers because they grew up with social networking and social media. Once books are electronic, relevant and social, too, they"ll start reading and writing books like crazy.
J. And, finally, the newspaper industry is dying. The old method of physically delivering blog entries on dead tree pulp is out-of-date. It"s very simple. Newspapers that embrace e-books will survive. Those that don"t, won"t. If you"d like to get a stark view of the relative economics of electronic vs. paper newspapers, check out a blog post on the Silicon Valley Insider . The blog did the math and determined that the New York Times could buy every single subscriber an Amazon Kindle e-book reader, and it would still cost them half as much as it will cost them to send paper newspapers for just one year. After decades of false starts, the e-book revolution is finally upon us. By this time next year, e-books will be totally mainstream.Young people will be keen on reading and writing books when books are electronic, relevant and social.

Artificial Intelligence(AI)
A. We often don"t notice it, but artificial intelligence (AI) is all around us. It is present in computer games, in the cruise control in our cars and the servers that route our email. In June 2002, a robot called Gaak gave an alarming demonstration of its independence. It made a dash for freedom from an exhibit at the Magna science centre in Rotherham. Gaak crept along a barrier until it found a gap and squeezed through. Having left the building, it reached Magna"s exit by the M1 motorway before it was discovered.
B. So, can a machine behave like a person This question underlies artificial intelligence, the study of intelligent behavior in machines. In the 1980s, AI research focused on creating machines that could solve problems and reason like humans. One of the most difficult problems in artificial intelligence is that of consciousness. A consciousness gives us feelings and makes us aware of our own existence. But scientists have found it difficult getting robots to carry out even the simplest of cognitive tasks. Creating a self-aware robot with real feelings is a significant challenge faced by scientists hoping to imitate human intelligence in a machine. Since the early 1990s, researchers have concentrated on developing smaller, independent robots instead of trying to recreate human intelligence. The model for many of these machines is insect intelligence, which is—in its own way—very sophisticated.
C. When it is completed in late 2004, the world"s most powerful computer will be ASCI Purple, built by IBM. It is expected to carry out 100 trillion operations per second (or 100 teraflops). A super-computer with double this processing power is expected within the next two years. It is being built to replace ASCI White—formerly the world"s most powerful computer—which occupies a space the size of two basketball courts at the Lawrence Livermore National Laboratory in Livermore, California. A spokesman for IBM said that ASCI Purple was approaching the processing power of the human brain. But some scientists believe our brains can carry out around 10,000 trillion operations per second. HAL, the supercomputer that rebels against its human handlers in the film 2001: A Space Odyssey (1968), is a bold reference to IBM. The letters H, A and L, precede I, B and M in the alphabet.
D. In 1950, mathematician Alan Turing devised a test to identify whether a machine displayed intelligence. In the Turing Test, two people (A and B) sit in a closed room, while an interrogator (询问者) (C) sits outside. Person A tries to fool the interrogator about their gender, while person B tries to assist the interrogator in their identification. Turing suggested a machine take the place of person A. If the machine consistently fooled the human interrogator, it was likely to be intelligent.
E. The possible dangers posed by intelligent machines have inspired countless science fiction films. In The Terminator (1984), a computer network attacks the human race in order to achieve control. This network then manufactures intelligent robots called "Terminators" which it programs to destroy human survivors. In The Matrix (1999) and The Matrix Reloaded (2003), a machine enslaves humanity, using people as batteries to power its mainframe. Steven Spielberg"s AI: Artificial Intelligence (2002) paints a more sympathetic view of artificial life, depicting sensitive robots that are abused by brutal, selfish human masters.
F. One place where artificial intelligence has found a natural home is in the development of computer games. AI in computer games is becoming increasingly sophisticated as consumer appetites for better, faster, more challenging games grows. In games, AI is often present in the opponents you play against, or in allies or other team members.
G. In 1997, then world chess champion Garry Kasparov played against IBM"s Deep Blue supercomputer—and lost. After six games, the mighty Kasparov lost 2.5 to 3.5 to the silicon upstart. In February 2003, Kasparov saved some credibility for humanity by drawing against the Israeli-built supercomputer Deep Junior. Kasparov went on to draw 2-2 against US company X3D Technologies" supercomputer X3D Fritz in November 2003, proving that the human brain can keep up with the latest developments in computing (at least in chess).
H. Despite these entertaining applications, the original point of AI research was to create machines that could understand us. At the Massachusetts Institute of Technology (MIT), scientists have designed a robot called Kismet that can have realistic conversations with people. Kismet is capable of seven different facial expressions and can vary the tone of its voice. It also adjusts its gaze and the direction of its head towards the person it is speaking to. Scientists at HP have designed an electronic DJ. The "hpDJ" selects beats and baselines from its memory bank and mixes them. Its makers say it could be made to react to the mood of clubbers. At the University of Texas, Dallas, researchers have designed a lifelike human face capable of 28 facial movements, including smiling, sneering, furrowing its brow and arching its eyebrows. It could be used to put a human face to the artificial brains of the future.
I. A computer program developed at Brandeis University in Massachusetts has learnt how to design and build bridges, cranes and tables all by itself. It reinvented support structures such as the cantilever and the triangle without prior knowledge of them. Credit card companies use a computer program called The Falcon to detect card fraud. The Falcon works by constantly updating a profile of how customers use their credit cards. It then looks for uncharacteristic patterns of credit card use in the data. A robotic head built by a Scottish robotics company can determine a woman"s attractiveness. It works by examining faces to determine how "feminine" or "masculine" they are. It doesn"t work in reverse because men"s appeal is supposedly not based as much on looks. Perhaps jokingly, researchers say it could be put to use as an artificial receptionist. Robots designed for the consumer market and employing very basic forms of AI have become increasingly popular in recent years. Sony"s Aibo robot dog behaves like a puppy when it is first activated. But it "learns" new behavior as it spends more time with its human owner. A software program called FACES could stop mid-air collisions between planes. When tested in a flight simulator (模拟器), the software prevented a pile-up between 35 planes sharing airspace.
J. Over the coming century, breakthroughs in nanotechnology, the science of ultra-small machines constructed at the molecular level, may help us build more sophisticated machines that are more compact. We may also see breakthroughs from scientists who are experimenting with connecting biological cells to silicon circuits—a phenomenon called wetware.Kismet is a special robot that can demonstrate some kind of social skills.

E. The possible dangers posed by intelligent machines have inspired countless science fiction films. In The Terminator (1984), a computer network attacks the human race in order to achieve control. This network then manufactures intelligent robots called "Terminators" which it programs to destroy human survivors. In The Matrix (1999) and The Matrix Reloaded (2003), a machine enslaves humanity, using people as batteries to power its mainframe. Steven Spielberg"s AI: Artificial Intelligence (2002) paints a more sympathetic view of artificial life, depicting sensitive robots that are abused by brutal, selfish human masters.
F. One place where artificial intelligence has found a natural home is in the development of computer games. AI in computer games is becoming increasingly sophisticated as consumer appetites for better, faster, more challenging games grows. In games, AI is often present in the opponents you play against, or in allies or other team members.
G. In 1997, then world chess champion Garry Kasparov played against IBM"s Deep Blue supercomputer—and lost. After six games, the mighty Kasparov lost 2.5 to 3.5 to the silicon upstart. In February 2003, Kasparov saved some credibility for humanity by drawing against the Israeli-built supercomputer Deep Junior. Kasparov went on to draw 2-2 against US company X3D Technologies" supercomputer X3D Fritz in November 2003, proving that the human brain can keep up with the latest developments in computing (at least in chess).
H. Despite these entertaining applications, the original point of AI research was to create machines that could understand us. At the Massachusetts Institute of Technology (MIT), scientists have designed a robot called Kismet that can have realistic conversations with people. Kismet is capable of seven different facial expressions and can vary the tone of its voice. It also adjusts its gaze and the direction of its head towards the person it is speaking to. Scientists at HP have designed an electronic DJ. The "hpDJ" selects beats and baselines from its memory bank and mixes them. Its makers say it could be made to react to the mood of clubbers. At the University of Texas, Dallas, researchers have designed a lifelike human face capable of 28 facial movements, including smiling, sneering, furrowing its brow and arching its eyebrows. It could be used to put a human face to the artificial brains of the future.
I. A computer program developed at Brandeis University in Massachusetts has learnt how to design and build bridges, cranes and tables all by itself. It reinvented support structures such as the cantilever and the triangle without prior knowledge of them. Credit card companies use a computer program called The Falcon to detect card fraud. The Falcon works by constantly updating a profile of how customers use their credit cards. It then looks for uncharacteristic patterns of credit card use in the data. A robotic head built by a Scottish robotics company can determine a woman"s attractiveness. It works by examining faces to determine how "feminine" or "masculine" they are. It doesn"t work in reverse because men"s appeal is supposedly not based as much on looks. Perhaps jokingly, researchers say it could be put to use as an artificial receptionist. Robots designed for the consumer market and employing very basic forms of AI have become increasingly popular in recent years. Sony"s Aibo robot dog behaves like a puppy when it is first activated. But it "learns" new behavior as it spends more time with its human owner. A software program called FACES could stop mid-air collisions between planes. When tested in a flight simulator (模拟器), the software prevented a pile-up between 35 planes sharing airspace.
J. Over the coming century, breakthroughs in nanotechnology, the science of ultra-small machines constructed at the molecular level, may help us build more sophisticated machines that are more compact. We may also see breakthroughs from scientists who are experimenting with connecting biological cells to silicon circuits—a phenomenon called wetware.Increasingly sophisticated AI is demanded for the development of more challenging computer games.

Are we ready for the library of the future
A. Librarians today will tell you their job is not so much to take care of books but to give people access to information in all forms. Since librarians, like so many people, believe that the entire universe of commerce, communication and information is moving to digital form, they are on a reform to give people access to the Internet—to prevent them from becoming second-class citizens in an all-digital world. Something funny happened on the road to the digital library of the future, though. Far from becoming keepers of the keys to the Grand Database of Universal Knowledge, today"s librarians are increasingly finding themselves in an unexpected, overloaded role: They have become the general public"s last-resort providers of tech support.
B. It wasn"t supposed to be this way. Today"s libraries offer a variety of media and social-cultural events—they are "blended libraries," to use a term created by Kathleen Imhoff, assistant director of the Broward County Library of Fort Lauderdale, Florida. At the newly remodeled San Francisco Public Library, the computers are prominently displayed in the center of the library building while the books are all but hidden on the periphery (外围). Imhoff"s own library has word processing and other types of software for visitors to use, Internet access, audio CDs, videotapes, concerts, lectures, books and periodicals in three forms (print, microfiche and digital). Many libraries have found that this kind of "blending" is hugely popular in their communities, and librarians explain the changes in their institutions" roles by pointing to the public demand for these new services. But other trends are at work, too.
C. For some time, libraries have been automating their back-end, behind-the-desk functions for reasons of cost and convenience, just like any other business. Now, the computers have moved out from behind librarians" desks and onto the floor where the visitors are. This means that, suddenly, library-goers will have to know how to use those computers. This sounds reasonable enough until you take a close look. Unfortunately, the same technology that cuts costs and relieves librarians of work behind the scenes increases it for the public—and for the librarians at the front desk who have to help the public figure out how to use the technology. The unhappy result: People are simply not finding the information they seek.
D. If you are just coming to the library to read a book for pleasure and you know what a card catalog is and you have some basic computer skills, then you are going to be OK. But if you are trying to find some specific information—say, whether software in the classroom helps kids learn better or the causes of lung cancer or the basic procedure for doing a cost-benefit analysis of computer systems (three topics I have actually tried to look up in the San Francisco library)—then you"re in trouble.
E. To begin with, library visitors must now be able to type, to use a mouse and a menu and to understand the various types of computer interfaces (terminal text, windows and browsers). It"s also nice if you know 17 different ways to quit a program, which electronic databases you should look in for what kinds of information, the grammar necessary to define your search and the Library of Congress" controlled vocabulary. After I had been to the new San Francisco library three times, I started keeping a folder of instructions on how to do a keyword search, since I would forget between visits.
F. Probably 50% of the population has never used a computer, fewer know how to type and almost nobody knows anything about electronic databases or searching grammar. As a result, the public library is now engaged in a massive attempt to teach computer literacy to the entire country. Some librarians compare it to the adult literacy programs the library also sponsors, but this is on a far larger scale—and less closely tied to the library"s traditional mission. The response at each library system has been different. Some libraries actually give courses in word processing, accounting program and so on. But even at libraries where the staff has resisted becoming computer trainers, they are still forced to devote significant resources to the problem.
G. Such has been the case in San Francisco, where people with disabilities can sign up to use the voice-recognition program Dragon Dictate—but only if they can prove they already know how to use the software. The librarians have neither the time nor the peculiar skill (nor the time to develop the skill) to teach it to them. At the reference desks, librarians try not to spend a lot of time teaching people the basics of how to use the computer, but sometimes it"s unavoidable. "We try to get them started," says business librarian John Kenney. "We let them do as much as they can on their own and they come get us. It"s certainly a big problem."
H. The San Francisco library offers classes on its own electronic catalog, commercial periodical indexes and the Internet twice a week as well as occasional lectures about the Internet. Although it seems odd to me that people now need to take a two-hour class before they can use the library, the classes are always full. But despite the excellent teachers, two hours is simply not enough to meet the needs of the students, many of whom have never used a computer before in their lives and many of whom simply can"t type. When I took the class one Tuesday, the man sitting next to me said he has used the library"s computer catalog many times, but he keeps making typing mistakes without knowing it. This unexpectedly throws him into the wrong screens and he doesn"t know how to get back. On the floor, he repeatedly has to ask a librarian for help.
I. "Providing technology does not mean people can use the technology," says Marc Webb, a San Francisco librarian and one of the teachers. "Half the voters are still trying to read English." The library has also had to deal with the practical difficulties of making its catalog accessible via the Internet, a new service many libraries are starting to offer. "It"s absolutely overwhelming," Webb says. "Everyone is getting to us with multiple transports, they"re all using different software, they have Winsock or Telnet set up differently, and suddenly the library is forced to become a hardware and software help desk. When you"re trying to tell someone over the telephone how to set up Winsock through AOL when this is the first time they"ve ever used a computer, it"s very difficult."Libraries have been automating their back-end, behind-the-desk functions in consideration of cost and convenience.

Here comes the e-book revolution
A. At what temperature do electronic books catch fire We"re going to find out sometime this year. E-book sales are about to ignite. On Monday, Amazon.com is expected to unveil a new version of its Kindle reader. It will probably be a lot better and a little cheaper than the first version. But the real news already broke this week: A company spokesman announced that Amazon plans to offer Kindle books on Ceil Phones. This news countered Google"s announcement that the 1.5 million public domain books available on its Google Book Search offering will soon be available (free, of course) via a new Cell Phone application.
B. I believe that Cell Phones will quickly outpace the dedicated e-book readers, including the Kindle, as the platform of choice for e-book readers. Leading the pack The iPhone, ironically. It"s worth noting that Amazon.com sold more Kindles (at least 500,000) in its first year of sales than Apple sold iPods in its first year (378,000). Apple may not understand the value of e-books, but iPhone users will embrace them anyway. The reason is simple: The iPhone has a huge, high-quality screen. And its user base includes millions of people who love to do everything on their iPhones, including reading, which they"re already doing with online content. I (and others) have been predicting for some time that Apple will ship a killer tablet at some point. This device, I believe, will have the iPhone user interface and a super high-quality screen. It will be ideal for reading e-books as well.
C. Just because e-books are available on better (the new Kindle) and more (all Cell Phones) devices doesn"t mean people will read them. But mark my words, read them they will. Six trends will conspire (共同促成) over the next year to drive e-book reading to levels that will surprise just about everybody.
D. The economy is in the tank, and people are looking to cut costs any way they can. An Amazon Kindle pays for itself after the purchase of 20 or 30 books, then starts paying dividends. You save big on books, magazines and newspapers. These savings will grow even more attractive as the recession deepens.
E. Interest in protecting the environment just keeps growing and growing. The idea of getting a daily newspaper or a weekly or monthly magazine on paper seems incredibly wasteful to the point of decadence. Environmental consciousness will drive e-book acceptance.
F. The book publishing industry is one of the most backward, musty, out-of-date businesses in our economy. While every other kind of information moves at the speed of light, the process of publishing a book is like something from the Middle Ages. For authors, it can take months to even find a literary agent willing to represent their work. Then the agent takes months to find a publisher. Then it takes ages for the publishing company to get the book out there. People are already circumventing (设法回避) all this by self-publishing. The self-publishing industry is the only area of paper-book publishing that"s thriving right now. Soon enough, a huge number of authors are finally going to get fed up with the publishing industry and just self-publish electronically. They"ll hire their own freelance editors, and do the marketing themselves. The publication of a finished manuscript will take minutes, rather than months.
G. Old-school thinkers in the publishing industry will lament (悲叹) the slap-dash nature of self-published e-books, and sniff" that books are no longer published with the quality and care that they used to. (Never mind that book publishers abandoned high standards years ago in previous cost-cutting initiatives.) The world will pass them by as the book industry undergoes the same transition that happened with the media and blogs. First, the media didn"t understand blogs. Then they invalidated them. Then they accepted them. And now blogs are where the credibility is. Every columnist and reporter has a blog, and now major TV news programs are built around the opinions of bloggers. A similar transformation will take place about the credibility of serf-published and electronic books.
H. Like the move from silent pictures to "talkies," the transition to electronic publishing will prove fatal to laggards. Those aggressively pursuing and developing e-books will rise to take control of the publishing industry. Part of this revolution will happen in e-book marketing. The new generation of e-book publishers will leverage social media, contextual advertising and other innovations. For anyone who spends time online, specific e-book titles will increasingly be advertised and marketed and integrated into other content. E-books, now mostly invisible, will soon be everywhere.
I. The shift from print to electronic will change the nature of the book itself. Many books will be shorter. They"ll be more timely and culturally relevant. They"ll be more colorfully and engagingly written. And they"ll go after young readers like nothing before. As in Japan, this will spark a new cultural phenomenon of young people not just reading, but also writing novels and other book types on their mobile devices. The idea that "people don"t read anymore," especially young people, will be revealed as false. Young people today read more, and write a lot more, than any generation in history. To date, they"ve been unexcited about books, magazines and newspapers because they grew up with social networking and social media. Once books are electronic, relevant and social, too, they"ll start reading and writing books like crazy.
J. And, finally, the newspaper industry is dying. The old method of physically delivering blog entries on dead tree pulp is out-of-date. It"s very simple. Newspapers that embrace e-books will survive. Those that don"t, won"t. If you"d like to get a stark view of the relative economics of electronic vs. paper newspapers, check out a blog post on the Silicon Valley Insider . The blog did the math and determined that the New York Times could buy every single subscriber an Amazon Kindle e-book reader, and it would still cost them half as much as it will cost them to send paper newspapers for just one year. After decades of false starts, the e-book revolution is finally upon us. By this time next year, e-books will be totally mainstream.The credibility of blogs used to be not accepted by the media.

Artificial Intelligence(AI)
A. We often don"t notice it, but artificial intelligence (AI) is all around us. It is present in computer games, in the cruise control in our cars and the servers that route our email. In June 2002, a robot called Gaak gave an alarming demonstration of its independence. It made a dash for freedom from an exhibit at the Magna science centre in Rotherham. Gaak crept along a barrier until it found a gap and squeezed through. Having left the building, it reached Magna"s exit by the M1 motorway before it was discovered.
B. So, can a machine behave like a person This question underlies artificial intelligence, the study of intelligent behavior in machines. In the 1980s, AI research focused on creating machines that could solve problems and reason like humans. One of the most difficult problems in artificial intelligence is that of consciousness. A consciousness gives us feelings and makes us aware of our own existence. But scientists have found it difficult getting robots to carry out even the simplest of cognitive tasks. Creating a self-aware robot with real feelings is a significant challenge faced by scientists hoping to imitate human intelligence in a machine. Since the early 1990s, researchers have concentrated on developing smaller, independent robots instead of trying to recreate human intelligence. The model for many of these machines is insect intelligence, which is—in its own way—very sophisticated.
C. When it is completed in late 2004, the world"s most powerful computer will be ASCI Purple, built by IBM. It is expected to carry out 100 trillion operations per second (or 100 teraflops). A super-computer with double this processing power is expected within the next two years. It is being built to replace ASCI White—formerly the world"s most powerful computer—which occupies a space the size of two basketball courts at the Lawrence Livermore National Laboratory in Livermore, California. A spokesman for IBM said that ASCI Purple was approaching the processing power of the human brain. But some scientists believe our brains can carry out around 10,000 trillion operations per second. HAL, the supercomputer that rebels against its human handlers in the film 2001: A Space Odyssey (1968), is a bold reference to IBM. The letters H, A and L, precede I, B and M in the alphabet.
D. In 1950, mathematician Alan Turing devised a test to identify whether a machine displayed intelligence. In the Turing Test, two people (A and B) sit in a closed room, while an interrogator (询问者) (C) sits outside. Person A tries to fool the interrogator about their gender, while person B tries to assist the interrogator in their identification. Turing suggested a machine take the place of person A. If the machine consistently fooled the human interrogator, it was likely to be intelligent.
E. The possible dangers posed by intelligent machines have inspired countless science fiction films. In The Terminator (1984), a computer network attacks the human race in order to achieve control. This network then manufactures intelligent robots called "Terminators" which it programs to destroy human survivors. In The Matrix (1999) and The Matrix Reloaded (2003), a machine enslaves humanity, using people as batteries to power its mainframe. Steven Spielberg"s AI: Artificial Intelligence (2002) paints a more sympathetic view of artificial life, depicting sensitive robots that are abused by brutal, selfish human masters.
F. One place where artificial intelligence has found a natural home is in the development of computer games. AI in computer games is becoming increasingly sophisticated as consumer appetites for better, faster, more challenging games grows. In games, AI is often present in the opponents you play against, or in allies or other team members.

It could be used to put a human face to the artificial brains of the future.
I. A computer program developed at Brandeis University in Massachusetts has learnt how to design and build bridges, cranes and tables all by itself.

To date, they"ve been unexcited about books, magazines and newspapers because they grew up with social networking and social media. Once books are electronic, relevant and social, too, they"ll start reading and writing books like crazy.
J. And, finally, the newspaper industry is dying. The old method of physically delivering blog entries on dead tree pulp is out-of-date. It"s very simple. Newspapers that embrace e-books will survive. Those that don"t, won"t. If you"d like to get a stark view of the relative economics of electronic vs. paper newspapers, check out a blog post on the Silicon Valley Insider . The blog did the math and determined that the New York Times could buy every single subscriber an Amazon Kindle e-book reader, and it would still cost them half as much as it will cost them to send paper newspapers for just one year. After decades of false starts, the e-book revolution is finally upon us. By this time next year, e-books will be totally mainstream.It is said that a newspaper will survive only when it incorporates with e-books.

Artificial Intelligence(AI)
A. We often don"t notice it, but artificial intelligence (AI) is all around us. It is present in computer games, in the cruise control in our cars and the servers that route our email. In June 2002, a robot called Gaak gave an alarming demonstration of its independence. It made a dash for freedom from an exhibit at the Magna science centre in Rotherham. Gaak crept along a barrier until it found a gap and squeezed through. Having left the building, it reached Magna"s exit by the M1 motorway before it was discovered.
B. So, can a machine behave like a person This question underlies artificial intelligence, the study of intelligent behavior in machines. In the 1980s, AI research focused on creating machines that could solve problems and reason like humans. One of the most difficult problems in artificial intelligence is that of consciousness. A consciousness gives us feelings and makes us aware of our own existence. But scientists have found it difficult getting robots to carry out even the simplest of cognitive tasks. Creating a self-aware robot with real feelings is a significant challenge faced by scientists hoping to imitate human intelligence in a machine. Since the early 1990s, researchers have concentrated on developing smaller, independent robots instead of trying to recreate human intelligence. The model for many of these machines is insect intelligence, which is—in its own way—very sophisticated.
C. When it is completed in late 2004, the world"s most powerful computer will be ASCI Purple, built by IBM. It is expected to carry out 100 trillion operations per second (or 100 teraflops). A super-computer with double this processing power is expected within the next two years. It is being built to replace ASCI White—formerly the world"s most powerful computer—which occupies a space the size of two basketball courts at the Lawrence Livermore National Laboratory in Livermore, California. A spokesman for IBM said that ASCI Purple was approaching the processing power of the human brain. But some scientists believe our brains can carry out around 10,000 trillion operations per second. HAL, the supercomputer that rebels against its human handlers in the film 2001: A Space Odyssey (1968), is a bold reference to IBM. The letters H, A and L, precede I, B and M in the alphabet.
D. In 1950, mathematician Alan Turing devised a test to identify whether a machine displayed intelligence. In the Turing Test, two people (A and B) sit in a closed room, while an interrogator (询问者) (C) sits outside. Person A tries to fool the interrogator about their gender, while person B tries to assist the interrogator in their identification. Turing suggested a machine take the place of person A. If the machine consistently fooled the human interrogator, it was likely to be intelligent.
E. The possible dangers posed by intelligent machines have inspired countless science fiction films. In The Terminator (1984), a computer network attacks the human race in order to achieve control. This network then manufactures intelligent robots called "Terminators" which it programs to destroy human survivors. In The Matrix (1999) and The Matrix Reloaded (2003), a machine enslaves humanity, using people as batteries to power its mainframe. Steven Spielberg"s AI: Artificial Intelligence (2002) paints a more sympathetic view of artificial life, depicting sensitive robots that are abused by brutal, selfish human masters.
F. One place where artificial intelligence has found a natural home is in the development of computer games. AI in computer games is becoming increasingly sophisticated as consumer appetites for better, faster, more challenging games grows. In games, AI is often present in the opponents you play against, or in allies or other team members.
G. In 1997, then world chess champion Garry Kasparov played against IBM"s Deep Blue supercomputer—and lost. After six games, the mighty Kasparov lost 2.5 to 3.5 to the silicon upstart. In February 2003, Kasparov saved some credibility for humanity by drawing against the Israeli-built supercomputer Deep Junior. Kasparov went on to draw 2-2 against US company X3D Technologies" supercomputer X3D Fritz in November 2003, proving that the human brain can keep up with the latest developments in computing (at least in chess).
H. Despite these entertaining applications, the original point of AI research was to create machines that could understand us. At the Massachusetts Institute of Technology (MIT), scientists have designed a robot called Kismet that can have realistic conversations with people. Kismet is capable of seven different facial expressions and can vary the tone of its voice. It also adjusts its gaze and the direction of its head towards the person it is speaking to. Scientists at HP have designed an electronic DJ. The "hpDJ" selects beats and baselines from its memory bank and mixes them. Its makers say it could be made to react to the mood of clubbers. At the University of Texas, Dallas, researchers have designed a lifelike human face capable of 28 facial movements, including smiling, sneering, furrowing its brow and arching its eyebrows. It could be used to put a human face to the artificial brains of the future.
I. A computer program developed at Brandeis University in Massachusetts has learnt how to design and build bridges, cranes and tables all by itself. It reinvented support structures such as the cantilever and the triangle without prior knowledge of them. Credit card companies use a computer program called The Falcon to detect card fraud. The Falcon works by constantly updating a profile of how customers use their credit cards. It then looks for uncharacteristic patterns of credit card use in the data. A robotic head built by a Scottish robotics company can determine a woman"s attractiveness. It works by examining faces to determine how "feminine" or "masculine" they are. It doesn"t work in reverse because men"s appeal is supposedly not based as much on looks. Perhaps jokingly, researchers say it could be put to use as an artificial receptionist. Robots designed for the consumer market and employing very basic forms of AI have become increasingly popular in recent years. Sony"s Aibo robot dog behaves like a puppy when it is first activated. But it "learns" new behavior as it spends more time with its human owner. A software program called FACES could stop mid-air collisions between planes. When tested in a flight simulator (模拟器), the software prevented a pile-up between 35 planes sharing airspace.
J. Over the coming century, breakthroughs in nanotechnology, the science of ultra-small machines constructed at the molecular level, may help us build more sophisticated machines that are more compact. We may also see breakthroughs from scientists who are experimenting with connecting biological cells to silicon circuits—a phenomenon called wetware.Credit card fraud can be detected with the help of a computer program called The Falcon.

填空题

Are we ready for the library of the future
A. Librarians today will tell you their job is not so much to take care of books but to give people access to information in all forms. Since librarians, like so many people, believe that the entire universe of commerce, communication and information is moving to digital form, they are on a reform to give people access to the Internet—to prevent them from becoming second-class citizens in an all-digital world. Something funny happened on the road to the digital library of the future, though. Far from becoming keepers of the keys to the Grand Database of Universal Knowledge, today"s librarians are increasingly finding themselves in an unexpected, overloaded role: They have become the general public"s last-resort providers of tech support.
B. It wasn"t supposed to be this way. Today"s libraries offer a variety of media and social-cultural events—they are "blended libraries," to use a term created by Kathleen Imhoff, assistant director of the Broward County Library of Fort Lauderdale, Florida. At the newly remodeled San Francisco Public Library, the computers are prominently displayed in the center of the library building while the books are all but hidden on the periphery (外围). Imhoff"s own library has word processing and other types of software for visitors to use, Internet access, audio CDs, videotapes, concerts, lectures, books and periodicals in three forms (print, microfiche and digital). Many libraries have found that this kind of "blending" is hugely popular in their communities, and librarians explain the changes in their institutions" roles by pointing to the public demand for these new services. But other trends are at work, too.
C. For some time, libraries have been automating their back-end, behind-the-desk functions for reasons of cost and convenience, just like any other business. Now, the computers have moved out from behind librarians" desks and onto the floor where the visitors are. This means that, suddenly, library-goers will have to know how to use those computers. This sounds reasonable enough until you take a close look. Unfortunately, the same technology that cuts costs and relieves librarians of work behind the scenes increases it for the public—and for the librarians at the front desk who have to help the public figure out how to use the technology. The unhappy result: People are simply not finding the information they seek.
D. If you are just coming to the library to read a book for pleasure and you know what a card catalog is and you have some basic computer skills, then you are going to be OK. But if you are trying to find some specific information—say, whether software in the classroom helps kids learn better or the causes of lung cancer or the basic procedure for doing a cost-benefit analysis of computer systems (three topics I have actually tried to look up in the San Francisco library)—then you"re in trouble.
E. To begin with, library visitors must now be able to type, to use a mouse and a menu and to understand the various types of computer interfaces (terminal text, windows and browsers). It"s also nice if you know 17 different ways to quit a program, which electronic databases you should look in for what kinds of information, the grammar necessary to define your search and the Library of Congress" controlled vocabulary. After I had been to the new San Francisco library three times, I started keeping a folder of instructions on how to do a keyword search, since I would forget between visits.
F. Probably 50% of the population has never used a computer, fewer know how to type and almost nobody knows anything about electronic databases or searching grammar. As a result, the public library is now engaged in a massive attempt to teach computer literacy to the entire country. Some librarians compare it to the adult literacy programs the library also sponsors, but this is on a far larger scale—and less closely tied to the library"s traditional mission. The response at each library system has been different. Some libraries actually give courses in word processing, accounting program and so on. But even at libraries where the staff has resisted becoming computer trainers, they are still forced to devote significant resources to the problem.
G. Such has been the case in San Francisco, where people with disabilities can sign up to use the voice-recognition program Dragon Dictate—but only if they can prove they already know how to use the software. The librarians have neither the time nor the peculiar skill (nor the time to develop the skill) to teach it to them. At the reference desks, librarians try not to spend a lot of time teaching people the basics of how to use the computer, but sometimes it"s unavoidable. "We try to get them started," says business librarian John Kenney. "We let them do as much as they can on their own and they come get us. It"s certainly a big problem."
H. The San Francisco library offers classes on its own electronic catalog, commercial periodical indexes and the Internet twice a week as well as occasional lectures about the Internet. Although it seems odd to me that people now need to take a two-hour class before they can use the library, the classes are always full. But despite the excellent teachers, two hours is simply not enough to meet the needs of the students, many of whom have never used a computer before in their lives and many of whom simply can"t type. When I took the class one Tuesday, the man sitting next to me said he has used the library"s computer catalog many times, but he keeps making typing mistakes without knowing it. This unexpectedly throws him into the wrong screens and he doesn"t know how to get back. On the floor, he repeatedly has to ask a librarian for help.
I. "Providing technology does not mean people can use the technology," says Marc Webb, a San Francisco librarian and one of the teachers. "Half the voters are still trying to read English." The library has also had to deal with the practical difficulties of making its catalog accessible via the Internet, a new service many libraries are starting to offer. "It"s absolutely overwhelming," Webb says. "Everyone is getting to us with multiple transports, they"re all using different software, they have Winsock or Telnet set up differently, and suddenly the library is forced to become a hardware and software help desk. When you"re trying to tell someone over the telephone how to set up Winsock through AOL when this is the first time they"ve ever used a computer, it"s very difficult."As 50% of the population may have never used a computer, the public library now has been engaged in computer literacy programs.

Here comes the e-book revolution
A. At what temperature do electronic books catch fire We"re going to find out sometime this year. E-book sales are about to ignite. On Monday, Amazon.com is expected to unveil a new version of its Kindle reader. It will probably be a lot better and a little cheaper than the first version. But the real news already broke this week: A company spokesman announced that Amazon plans to offer Kindle books on Ceil Phones. This news countered Google"s announcement that the 1.5 million public domain books available on its Google Book Search offering will soon be available (free, of course) via a new Cell Phone application.
B. I believe that Cell Phones will quickly outpace the dedicated e-book readers, including the Kindle, as the platform of choice for e-book readers. Leading the pack The iPhone, ironically. It"s worth noting that Amazon.com sold more Kindles (at least 500,000) in its first year of sales than Apple sold iPods in its first year (378,000). Apple may not understand the value of e-books, but iPhone users will embrace them anyway. The reason is simple: The iPhone has a huge, high-quality screen. And its user base includes millions of people who love to do everything on their iPhones, including reading, which they"re already doing with online content. I (and others) have been predicting for some time that Apple will ship a killer tablet at some point. This device, I believe, will have the iPhone user interface and a super high-quality screen. It will be ideal for reading e-books as well.
C. Just because e-books are available on better (the new Kindle) and more (all Cell Phones) devices doesn"t mean people will read them. But mark my words, read them they will. Six trends will conspire (共同促成) over the next year to drive e-book reading to levels that will surprise just about everybody.
D. The economy is in the tank, and people are looking to cut costs any way they can. An Amazon Kindle pays for itself after the purchase of 20 or 30 books, then starts paying dividends. You save big on books, magazines and newspapers. These savings will grow even more attractive as the recession deepens.
E. Interest in protecting the environment just keeps growing and growing. The idea of getting a daily newspaper or a weekly or monthly magazine on paper seems incredibly wasteful to the point of decadence. Environmental consciousness will drive e-book acceptance.
F. The book publishing industry is one of the most backward, musty, out-of-date businesses in our economy. While every other kind of information moves at the speed of light, the process of publishing a book is like something from the Middle Ages. For authors, it can take months to even find a literary agent willing to represent their work. Then the agent takes months to find a publisher. Then it takes ages for the publishing company to get the book out there. People are already circumventing (设法回避) all this by self-publishing. The self-publishing industry is the only area of paper-book publishing that"s thriving right now. Soon enough, a huge number of authors are finally going to get fed up with the publishing industry and just self-publish electronically. They"ll hire their own freelance editors, and do the marketing themselves. The publication of a finished manuscript will take minutes, rather than months.
G. Old-school thinkers in the publishing industry will lament (悲叹) the slap-dash nature of self-published e-books, and sniff" that books are no longer published with the quality and care that they used to. (Never mind that book publishers abandoned high standards years ago in previous cost-cutting initiatives.) The world will pass them by as the book industry undergoes the same transition that happened with the media and blogs. First, the media didn"t understand blogs. Then they invalidated them. Then they accepted them. And now blogs are where the credibility is. Every columnist and reporter has a blog, and now major TV news programs are built around the opinions of bloggers. A similar transformation will take place about the credibility of serf-published and electronic books.
H. Like the move from silent pictures to "talkies," the transition to electronic publishing will prove fatal to laggards. Those aggressively pursuing and developing e-books will rise to take control of the publishing industry. Part of this revolution will happen in e-book marketing. The new generation of e-book publishers will leverage social media, contextual advertising and other innovations. For anyone who spends time online, specific e-book titles will increasingly be advertised and marketed and integrated into other content. E-books, now mostly invisible, will soon be everywhere.
I. The shift from print to electronic will change the nature of the book itself. Many books will be shorter. They"ll be more timely and culturally relevant. They"ll be more colorfully and engagingly written. And they"ll go after young readers like nothing before. As in Japan, this will spark a new cultural phenomenon of young people not just reading, but also writing novels and other book types on their mobile devices. The idea that "people don"t read anymore," especially young people, will be revealed as false. Young people today read more, and write a lot more, than any generation in history. To date, they"ve been unexcited about books, magazines and newspapers because they grew up with social networking and social media. Once books are electronic, relevant and social, too, they"ll start reading and writing books like crazy.
J. And, finally, the newspaper industry is dying. The old method of physically delivering blog entries on dead tree pulp is out-of-date. It"s very simple. Newspapers that embrace e-books will survive. Those that don"t, won"t. If you"d like to get a stark view of the relative economics of electronic vs. paper newspapers, check out a blog post on the Silicon Valley Insider . The blog did the math and determined that the New York Times could buy every single subscriber an Amazon Kindle e-book reader, and it would still cost them half as much as it will cost them to send paper newspapers for just one year. After decades of false starts, the e-book revolution is finally upon us. By this time next year, e-books will be totally mainstream.The price of an Amazon Kindle is as much as an amount money of 20 or 30 books.

On Monday, Amazon.com is expected to unveil a new version of its Kindle reader. It will probably be a lot better and a little cheaper than the first version. But the real news already broke this week: A company spokesman announced that Amazon plans to offer Kindle books on Ceil Phones. This news countered Google"s announcement that the 1.5 million public domain books available on its Google Book Search offering will soon be available (free, of course) via a new Cell Phone application.
B. I believe that Cell Phones will quickly outpace the dedicated e-book readers, including the Kindle, as the platform of choice for e-book readers. Leading the pack The iPhone, ironically. It"s worth noting that Amazon.com sold more Kindles (at least 500,000) in its first year of sales than Apple sold iPods in its first year (378,000). Apple may not understand the value of e-books, but iPhone users will embrace them anyway. The reason is simple: The iPhone has a huge, high-quality screen. And its user base includes millions of people who love to do everything on their iPhones, including reading, which they"re already doing with online content. I (and others) have been predicting for some time that Apple will ship a killer tablet at some point. This device, I believe, will have the iPhone user interface and a super high-quality screen. It will be ideal for reading e-books as well.
C. Just because e-books are available on better (the new Kindle) and more (all Cell Phones) devices doesn"t mean people will read them. But mark my words, read them they will. Six trends will conspire (共同促成) over the next year to drive e-book reading to levels that will surprise just about everybody.
D. The economy is in the tank, and people are looking to cut costs any way they can. An Amazon Kindle pays for itself after the purchase of 20 or 30 books, then starts paying dividends. You save big on books, magazines and newspapers. These savings will grow even more attractive as the recession deepens.
E. Interest in protecting the environment just keeps growing and growing. The idea of getting a daily newspaper or a weekly or monthly magazine on paper seems incredibly wasteful to the point of decadence. Environmental consciousness will drive e-book acceptance.
F. The book publishing industry is one of the most backward, musty, out-of-date businesses in our economy. While every other kind of information moves at the speed of light, the process of publishing a book is like something from the Middle Ages. For authors, it can take months to even find a literary agent willing to represent their work. Then the agent takes months to find a publisher. Then it takes ages for the publishing company to get the book out there. People are already circumventing (设法回避) all this by self-publishing. The self-publishing industry is the only area of paper-book publishing that"s thriving right now. Soon enough, a huge number of authors are finally going to get fed up with the publishing industry and just self-publish electronically. They"ll hire their own freelance editors, and do the marketing themselves. The publication of a finished manuscript will take minutes, rather than months.
G. Old-school thinkers in the publishing industry will lament (悲叹) the slap-dash nature of self-published e-books, and sniff" that books are no longer published with the quality and care that they used to. (Never mind that book publishers abandoned high standards years ago in previous cost-cutting initiatives.) The world will pass them by as the book industry undergoes the same transition that happened with the media and blogs. First, the media didn"t understand blogs. Then they invalidated them. Then they accepted them. And now blogs are where the credibility is. Every columnist and reporter has a blog, and now major TV news programs are built around the opinions of bloggers. A similar transformation will take place about the credibility of serf-published and electronic books.
H. Like the move from silent pictures to "talkies," the transition to electronic publishing will prove fatal to laggards. Those aggressively pursuing and developing e-books will rise to take control of the publishing industry. Part of this revolution will happen in e-book marketing. The new generation of e-book publishers will leverage social media, contextual advertising and other innovations. For anyone who spends time online, specific e-book titles will increasingly be advertised and marketed and integrated into other content. E-books, now mostly invisible, will soon be everywhere.
I. The shift from print to electronic will change the nature of the book itself. Many books will be shorter. They"ll be more timely and culturally relevant. They"ll be more colorfully and engagingly written. And they"ll go after young readers like nothing before. As in Japan, this will spark a new cultural phenomenon of young people not just reading, but also writing novels and other book types on their mobile devices. The idea that "people don"t read anymore," especially young people, will be revealed as false. Young people today read more, and write a lot more, than any generation in history. To date, they"ve been unexcited about books, magazines and newspapers because they grew up with social networking and social media. Once books are electronic, relevant and social, too, they"ll start reading and writing books like crazy.
J. And, finally, the newspaper industry is dying. The old method of physically delivering blog entries on dead tree pulp is out-of-date. It"s very simple. Newspapers that embrace e-books will survive. Those that don"t, won"t. If you"d like to get a stark view of the relative economics of electronic vs. paper newspapers, check out a blog post on the Silicon Valley Insider . The blog did the math and determined that the New York Times could buy every single subscriber an Amazon Kindle e-book reader, and it would still cost them half as much as it will cost them to send paper newspapers for just one year. After decades of false starts, the e-book revolution is finally upon us. By this time next year, e-books will be totally mainstream.It was breaking news that Amazon announced it planned to offer Kindle books on cell phones.

Artificial Intelligence(AI)
A. We often don"t notice it, but artificial intelligence (AI) is all around us. It is present in computer games, in the cruise control in our cars and the servers that route our email. In June 2002, a robot called Gaak gave an alarming demonstration of its independence. It made a dash for freedom from an exhibit at the Magna science centre in Rotherham. Gaak crept along a barrier until it found a gap and squeezed through. Having left the building, it reached Magna"s exit by the M1 motorway before it was discovered.
B. So, can a machine behave like a person This question underlies artificial intelligence, the study of intelligent behavior in machines. In the 1980s, AI research focused on creating machines that could solve problems and reason like humans. One of the most difficult problems in artificial intelligence is that of consciousness. A consciousness gives us feelings and makes us aware of our own existence. But scientists have found it difficult getting robots to carry out even the simplest of cognitive tasks. Creating a self-aware robot with real feelings is a significant challenge faced by scientists hoping to imitate human intelligence in a machine. Since the early 1990s, researchers have concentrated on developing smaller, independent robots instead of trying to recreate human intelligence. The model for many of these machines is insect intelligence, which is—in its own way—very sophisticated.
C. When it is completed in late 2004, the world"s most powerful computer will be ASCI Purple, built by IBM. It is expected to carry out 100 trillion operations per second (or 100 teraflops). A super-computer with double this processing power is expected within the next two years. It is being built to replace ASCI White—formerly the world"s most powerful computer—which occupies a space the size of two basketball courts at the Lawrence Livermore National Laboratory in Livermore, California. A spokesman for IBM said that ASCI Purple was approaching the processing power of the human brain. But some scientists believe our brains can carry out around 10,000 trillion operations per second. HAL, the supercomputer that rebels against its human handlers in the film 2001: A Space Odyssey (1968), is a bold reference to IBM. The letters H, A and L, precede I, B and M in the alphabet.
D. In 1950, mathematician Alan Turing devised a test to identify whether a machine displayed intelligence. In the Turing Test, two people (A and B) sit in a closed room, while an interrogator (询问者) (C) sits outside. Person A tries to fool the interrogator about their gender, while person B tries to assist the interrogator in their identification. Turing suggested a machine take the place of person A. If the machine consistently fooled the human interrogator, it was likely to be intelligent.
E. The possible dangers posed by intelligent machines have inspired countless science fiction films. In The Terminator (1984), a computer network attacks the human race in order to achieve control. This network then manufactures intelligent robots called "Terminators" which it programs to destroy human survivors. In The Matrix (1999) and The Matrix Reloaded (2003), a machine enslaves humanity, using people as batteries to power its mainframe. Steven Spielberg"s AI: Artificial Intelligence (2002) paints a more sympathetic view of artificial life, depicting sensitive robots that are abused by brutal, selfish human masters.
F. One place where artificial intelligence has found a natural home is in the development of computer games. AI in computer games is becoming increasingly sophisticated as consumer appetites for better, faster, more challenging games grows. In games, AI is often present in the opponents you play against, or in allies or other team members.
G. In 1997, then world chess champion Garry Kasparov played against IBM"s Deep Blue supercomputer—and lost. After six games, the mighty Kasparov lost 2.5 to 3.5 to the silicon upstart. In February 2003, Kasparov saved some credibility for humanity by drawing against the Israeli-built supercomputer Deep Junior. Kasparov went on to draw 2-2 against US company X3D Technologies" supercomputer X3D Fritz in November 2003, proving that the human brain can keep up with the latest developments in computing (at least in chess).
H. Despite these entertaining applications, the original point of AI research was to create machines that could understand us. At the Massachusetts Institute of Technology (MIT), scientists have designed a robot called Kismet that can have realistic conversations with people. Kismet is capable of seven different facial expressions and can vary the tone of its voice. It also adjusts its gaze and the direction of its head towards the person it is speaking to. Scientists at HP have designed an electronic DJ. The "hpDJ" selects beats and baselines from its memory bank and mixes them. Its makers say it could be made to react to the mood of clubbers. At the University of Texas, Dallas, researchers have designed a lifelike human face capable of 28 facial movements, including smiling, sneering, furrowing its brow and arching its eyebrows. It could be used to put a human face to the artificial brains of the future.
I. A computer program developed at Brandeis University in Massachusetts has learnt how to design and build bridges, cranes and tables all by itself. It reinvented support structures such as the cantilever and the triangle without prior knowledge of them. Credit card companies use a computer program called The Falcon to detect card fraud. The Falcon works by constantly updating a profile of how customers use their credit cards. It then looks for uncharacteristic patterns of credit card use in the data. A robotic head built by a Scottish robotics company can determine a woman"s attractiveness. It works by examining faces to determine how "feminine" or "masculine" they are. It doesn"t work in reverse because men"s appeal is supposedly not based as much on looks. Perhaps jokingly, researchers say it could be put to use as an artificial receptionist. Robots designed for the consumer market and employing very basic forms of AI have become increasingly popular in recent years. Sony"s Aibo robot dog behaves like a puppy when it is first activated. But it "learns" new behavior as it spends more time with its human owner. A software program called FACES could stop mid-air collisions between planes. When tested in a flight simulator (模拟器), the software prevented a pile-up between 35 planes sharing airspace.
J. Over the coming century, breakthroughs in nanotechnology, the science of ultra-small machines constructed at the molecular level, may help us build more sophisticated machines that are more compact. We may also see breakthroughs from scientists who are experimenting with connecting biological cells to silicon circuits—a phenomenon called wetware.The phenomenon of wetware refers to connecting biological cells to silicon circuits.

Are we ready for the library of the future
A. Librarians today will tell you their job is not so much to take care of books but to give people access to information in all forms. Since librarians, like so many people, believe that the entire universe of commerce, communication and information is moving to digital form, they are on a reform to give people access to the Internet—to prevent them from becoming second-class citizens in an all-digital world. Something funny happened on the road to the digital library of the future, though. Far from becoming keepers of the keys to the Grand Database of Universal Knowledge, today"s librarians are increasingly finding themselves in an unexpected, overloaded role: They have become the general public"s last-resort providers of tech support.
B. It wasn"t supposed to be this way. Today"s libraries offer a variety of media and social-cultural events—they are "blended libraries," to use a term created by Kathleen Imhoff, assistant director of the Broward County Library of Fort Lauderdale, Florida. At the newly remodeled San Francisco Public Library, the computers are prominently displayed in the center of the library building while the books are all but hidden on the periphery (外围). Imhoff"s own library has word processing and other types of software for visitors to use, Internet access, audio CDs, videotapes, concerts, lectures, books and periodicals in three forms (print, microfiche and digital). Many libraries have found that this kind of "blending" is hugely popular in their communities, and librarians explain the changes in their institutions" roles by pointing to the public demand for these new services. But other trends are at work, too.
C. For some time, libraries have been automating their back-end, behind-the-desk functions for reasons of cost and convenience, just like any other business. Now, the computers have moved out from behind librarians" desks and onto the floor where the visitors are. This means that, suddenly, library-goers will have to know how to use those computers. This sounds reasonable enough until you take a close look. Unfortunately, the same technology that cuts costs and relieves librarians of work behind the scenes increases it for the public—and for the librarians at the front desk who have to help the public figure out how to use the technology. The unhappy result: People are simply not finding the information they seek.
D. If you are just coming to the library to read a book for pleasure and you know what a card catalog is and you have some basic computer skills, then you are going to be OK. But if you are trying to find some specific information—say, whether software in the classroom helps kids learn better or the causes of lung cancer or the basic procedure for doing a cost-benefit analysis of computer systems (three topics I have actually tried to look up in the San Francisco library)—then you"re in trouble.
E. To begin with, library visitors must now be able to type, to use a mouse and a menu and to understand the various types of computer interfaces (terminal text, windows and browsers). It"s also nice if you know 17 different ways to quit a program, which electronic databases you should look in for what kinds of information, the grammar necessary to define your search and the Library of Congress" controlled vocabulary. After I had been to the new San Francisco library three times, I started keeping a folder of instructions on how to do a keyword search, since I would forget between visits.
F. Probably 50% of the population has never used a computer, fewer know how to type and almost nobody knows anything about electronic databases or searching grammar. As a result, the public library is now engaged in a massive attempt to teach computer literacy to the entire country. Some librarians compare it to the adult literacy programs the library also sponsors, but this is on a far larger scale—and less closely tied to the library"s traditional mission. The response at each library system has been different. Some libraries actually give courses in word processing, accounting program and so on. But even at libraries where the staff has resisted becoming computer trainers, they are still forced to devote significant resources to the problem.
G. Such has been the case in San Francisco, where people with disabilities can sign up to use the voice-recognition program Dragon Dictate—but only if they can prove they already know how to use the software. The librarians have neither the time nor the peculiar skill (nor the time to develop the skill) to teach it to them. At the reference desks, librarians try not to spend a lot of time teaching people the basics of how to use the computer, but sometimes it"s unavoidable. "We try to get them started," says business librarian John Kenney. "We let them do as much as they can on their own and they come get us. It"s certainly a big problem."
H. The San Francisco library offers classes on its own electronic catalog, commercial periodical indexes and the Internet twice a week as well as occasional lectures about the Internet. Although it seems odd to me that people now need to take a two-hour class before they can use the library, the classes are always full. But despite the excellent teachers, two hours is simply not enough to meet the needs of the students, many of whom have never used a computer before in their lives and many of whom simply can"t type. When I took the class one Tuesday, the man sitting next to me said he has used the library"s computer catalog many times, but he keeps making typing mistakes without knowing it. This unexpectedly throws him into the wrong screens and he doesn"t know how to get back. On the floor, he repeatedly has to ask a librarian for help.
I. "Providing technology does not mean people can use the technology," says Marc Webb, a San Francisco librarian and one of the teachers. "Half the voters are still trying to read English." The library has also had to deal with the practical difficulties of making its catalog accessible via the Internet, a new service many libraries are starting to offer. "It"s absolutely overwhelming," Webb says. "Everyone is getting to us with multiple transports, they"re all using different software, they have Winsock or Telnet set up differently, and suddenly the library is forced to become a hardware and software help desk. When you"re trying to tell someone over the telephone how to set up Winsock through AOL when this is the first time they"ve ever used a computer, it"s very difficult."Library visitors have to know how to type and use a mouse if they want to seek information in the modern library.

Here comes the e-book revolution
A. At what temperature do electronic books catch fire We"re going to find out sometime this year. E-book sales are about to ignite. On Monday, Amazon.com is expected to unveil a new version of its Kindle reader. It will probably be a lot better and a little cheaper than the first version. But the real news already broke this week: A company spokesman announced that Amazon plans to offer Kindle books on Ceil Phones.

But if you are trying to find some specific information—say, whether software in the classroom helps kids learn better or the causes of lung cancer or the basic procedure for doing a cost-benefit analysis of computer systems (three topics I have actually tried to look up in the San Francisco library)—then you"re in trouble.
E. To begin with, library visitors must now be able to type, to use a mouse and a menu and to understand the various types of computer interfaces (terminal text, windows and browsers). It"s also nice if you know 17 different ways to quit a program, which electronic databases you should look in for what kinds of information, the grammar necessary to define your search and the Library of Congress" controlled vocabulary. After I had been to the new San Francisco library three times, I started keeping a folder of instructions on how to do a keyword search, since I would forget between visits.
F. Probably 50% of the population has never used a computer, fewer know how to type and almost nobody knows anything about electronic databases or searching grammar. As a result, the public library is now engaged in a massive attempt to teach computer literacy to the entire country. Some librarians compare it to the adult literacy programs the library also sponsors, but this is on a far larger scale—and less closely tied to the library"s traditional mission. The response at each library system has been different. Some libraries actually give courses in word processing, accounting program and so on. But even at libraries where the staff has resisted becoming computer trainers, they are still forced to devote significant resources to the problem.
G. Such has been the case in San Francisco, where people with disabilities can sign up to use the voice-recognition program Dragon Dictate—but only if they can prove they already know how to use the software. The librarians have neither the time nor the peculiar skill (nor the time to develop the skill) to teach it to them. At the reference desks, librarians try not to spend a lot of time teaching people the basics of how to use the computer, but sometimes it"s unavoidable. "We try to get them started," says business librarian John Kenney. "We let them do as much as they can on their own and they come get us. It"s certainly a big problem."
H. The San Francisco library offers classes on its own electronic catalog, commercial periodical indexes and the Internet twice a week as well as occasional lectures about the Internet. Although it seems odd to me that people now need to take a two-hour class before they can use the library, the classes are always full. But despite the excellent teachers, two hours is simply not enough to meet the needs of the students, many of whom have never used a computer before in their lives and many of whom simply can"t type. When I took the class one Tuesday, the man sitting next to me said he has used the library"s computer catalog many times, but he keeps making typing mistakes without knowing it. This unexpectedly throws him into the wrong screens and he doesn"t know how to get back. On the floor, he repeatedly has to ask a librarian for help.
I. "Providing technology does not mean people can use the technology," says Marc Webb, a San Francisco librarian and one of the teachers. "Half the voters are still trying to read English." The library has also had to deal with the practical difficulties of making its catalog accessible via the Internet, a new service many libraries are starting to offer. "It"s absolutely overwhelming," Webb says. "Everyone is getting to us with multiple transports, they"re all using different software, they have Winsock or Telnet set up differently, and suddenly the library is forced to become a hardware and software help desk. When you"re trying to tell someone over the telephone how to set up Winsock through AOL when this is the first time they"ve ever used a computer, it"s very difficult."If you have some basic knowledge of card catalogue and computer skills, you will be able to read a book for pleasure.

Here comes the e-book revolution
A. At what temperature do electronic books catch fire We"re going to find out sometime this year. E-book sales are about to ignite. On Monday, Amazon.com is expected to unveil a new version of its Kindle reader. It will probably be a lot better and a little cheaper than the first version. But the real news already broke this week: A company spokesman announced that Amazon plans to offer Kindle books on Ceil Phones. This news countered Google"s announcement that the 1.5 million public domain books available on its Google Book Search offering will soon be available (free, of course) via a new Cell Phone application.
B. I believe that Cell Phones will quickly outpace the dedicated e-book readers, including the Kindle, as the platform of choice for e-book readers. Leading the pack The iPhone, ironically. It"s worth noting that Amazon.com sold more Kindles (at least 500,000) in its first year of sales than Apple sold iPods in its first year (378,000). Apple may not understand the value of e-books, but iPhone users will embrace them anyway. The reason is simple: The iPhone has a huge, high-quality screen. And its user base includes millions of people who love to do everything on their iPhones, including reading, which they"re already doing with online content. I (and others) have been predicting for some time that Apple will ship a killer tablet at some point. This device, I believe, will have the iPhone user interface and a super high-quality screen. It will be ideal for reading e-books as well.
C. Just because e-books are available on better (the new Kindle) and more (all Cell Phones) devices doesn"t mean people will read them. But mark my words, read them they will. Six trends will conspire (共同促成) over the next year to drive e-book reading to levels that will surprise just about everybody.
D. The economy is in the tank, and people are looking to cut costs any way they can. An Amazon Kindle pays for itself after the purchase of 20 or 30 books, then starts paying dividends. You save big on books, magazines and newspapers. These savings will grow even more attractive as the recession deepens.
E. Interest in protecting the environment just keeps growing and growing. The idea of getting a daily newspaper or a weekly or monthly magazine on paper seems incredibly wasteful to the point of decadence. Environmental consciousness will drive e-book acceptance.
F. The book publishing industry is one of the most backward, musty, out-of-date businesses in our economy. While every other kind of information moves at the speed of light, the process of publishing a book is like something from the Middle Ages. For authors, it can take months to even find a literary agent willing to represent their work. Then the agent takes months to find a publisher. Then it takes ages for the publishing company to get the book out there. People are already circumventing (设法回避) all this by self-publishing. The self-publishing industry is the only area of paper-book publishing that"s thriving right now. Soon enough, a huge number of authors are finally going to get fed up with the publishing industry and just self-publish electronically. They"ll hire their own freelance editors, and do the marketing themselves. The publication of a finished manuscript will take minutes, rather than months.
G. Old-school thinkers in the publishing industry will lament (悲叹) the slap-dash nature of self-published e-books, and sniff" that books are no longer published with the quality and care that they used to. (Never mind that book publishers abandoned high standards years ago in previous cost-cutting initiatives.) The world will pass them by as the book industry undergoes the same transition that happened with the media and blogs. First, the media didn"t understand blogs. Then they invalidated them. Then they accepted them. And now blogs are where the credibility is. Every columnist and reporter has a blog, and now major TV news programs are built around the opinions of bloggers. A similar transformation will take place about the credibility of serf-published and electronic books.
H. Like the move from silent pictures to "talkies," the transition to electronic publishing will prove fatal to laggards. Those aggressively pursuing and developing e-books will rise to take control of the publishing industry. Part of this revolution will happen in e-book marketing. The new generation of e-book publishers will leverage social media, contextual advertising and other innovations. For anyone who spends time online, specific e-book titles will increasingly be advertised and marketed and integrated into other content. E-books, now mostly invisible, will soon be everywhere.
I. The shift from print to electronic will change the nature of the book itself. Many books will be shorter. They"ll be more timely and culturally relevant. They"ll be more colorfully and engagingly written. And they"ll go after young readers like nothing before. As in Japan, this will spark a new cultural phenomenon of young people not just reading, but also writing novels and other book types on their mobile devices. The idea that "people don"t read anymore," especially young people, will be revealed as false. Young people today read more, and write a lot more, than any generation in history. To date, they"ve been unexcited about books, magazines and newspapers because they grew up with social networking and social media. Once books are electronic, relevant and social, too, they"ll start reading and writing books like crazy.
J. And, finally, the newspaper industry is dying. The old method of physically delivering blog entries on dead tree pulp is out-of-date. It"s very simple. Newspapers that embrace e-books will survive. Those that don"t, won"t. If you"d like to get a stark view of the relative economics of electronic vs. paper newspapers, check out a blog post on the Silicon Valley Insider . The blog did the math and determined that the New York Times could buy every single subscriber an Amazon Kindle e-book reader, and it would still cost them half as much as it will cost them to send paper newspapers for just one year. After decades of false starts, the e-book revolution is finally upon us. By this time next year, e-books will be totally mainstream.At present, the book publishing industry is in a backward state.

Artificial Intelligence(AI)
A. We often don"t notice it, but artificial intelligence (AI) is all around us. It is present in computer games, in the cruise control in our cars and the servers that route our email. In June 2002, a robot called Gaak gave an alarming demonstration of its independence. It made a dash for freedom from an exhibit at the Magna science centre in Rotherham. Gaak crept along a barrier until it found a gap and squeezed through. Having left the building, it reached Magna"s exit by the M1 motorway before it was discovered.
B. So, can a machine behave like a person This question underlies artificial intelligence, the study of intelligent behavior in machines. In the 1980s, AI research focused on creating machines that could solve problems and reason like humans. One of the most difficult problems in artificial intelligence is that of consciousness. A consciousness gives us feelings and makes us aware of our own existence. But scientists have found it difficult getting robots to carry out even the simplest of cognitive tasks. Creating a self-aware robot with real feelings is a significant challenge faced by scientists hoping to imitate human intelligence in a machine. Since the early 1990s, researchers have concentrated on developing smaller, independent robots instead of trying to recreate human intelligence. The model for many of these machines is insect intelligence, which is—in its own way—very sophisticated.
C. When it is completed in late 2004, the world"s most powerful computer will be ASCI Purple, built by IBM. It is expected to carry out 100 trillion operations per second (or 100 teraflops). A super-computer with double this processing power is expected within the next two years. It is being built to replace ASCI White—formerly the world"s most powerful computer—which occupies a space the size of two basketball courts at the Lawrence Livermore National Laboratory in Livermore, California. A spokesman for IBM said that ASCI Purple was approaching the processing power of the human brain. But some scientists believe our brains can carry out around 10,000 trillion operations per second. HAL, the supercomputer that rebels against its human handlers in the film 2001: A Space Odyssey (1968), is a bold reference to IBM. The letters H, A and L, precede I, B and M in the alphabet.
D. In 1950, mathematician Alan Turing devised a test to identify whether a machine displayed intelligence. In the Turing Test, two people (A and B) sit in a closed room, while an interrogator (询问者) (C) sits outside. Person A tries to fool the interrogator about their gender, while person B tries to assist the interrogator in their identification. Turing suggested a machine take the place of person A. If the machine consistently fooled the human interrogator, it was likely to be intelligent.
E. The possible dangers posed by intelligent machines have inspired countless science fiction films. In The Terminator (1984), a computer network attacks the human race in order to achieve control. This network then manufactures intelligent robots called "Terminators" which it programs to destroy human survivors. In The Matrix (1999) and The Matrix Reloaded (2003), a machine enslaves humanity, using people as batteries to power its mainframe. Steven Spielberg"s AI: Artificial Intelligence (2002) paints a more sympathetic view of artificial life, depicting sensitive robots that are abused by brutal, selfish human masters.
F. One place where artificial intelligence has found a natural home is in the development of computer games. AI in computer games is becoming increasingly sophisticated as consumer appetites for better, faster, more challenging games grows. In games, AI is often present in the opponents you play against, or in allies or other team members.
G. In 1997, then world chess champion Garry Kasparov played against IBM"s Deep Blue supercomputer—and lost. After six games, the mighty Kasparov lost 2.5 to 3.5 to the silicon upstart. In February 2003, Kasparov saved some credibility for humanity by drawing against the Israeli-built supercomputer Deep Junior. Kasparov went on to draw 2-2 against US company X3D Technologies" supercomputer X3D Fritz in November 2003, proving that the human brain can keep up with the latest developments in computing (at least in chess).
H. Despite these entertaining applications, the original point of AI research was to create machines that could understand us. At the Massachusetts Institute of Technology (MIT), scientists have designed a robot called Kismet that can have realistic conversations with people. Kismet is capable of seven different facial expressions and can vary the tone of its voice. It also adjusts its gaze and the direction of its head towards the person it is speaking to. Scientists at HP have designed an electronic DJ. The "hpDJ" selects beats and baselines from its memory bank and mixes them. Its makers say it could be made to react to the mood of clubbers. At the University of Texas, Dallas, researchers have designed a lifelike human face capable of 28 facial movements, including smiling, sneering, furrowing its brow and arching its eyebrows. It could be used to put a human face to the artificial brains of the future.
I. A computer program developed at Brandeis University in Massachusetts has learnt how to design and build bridges, cranes and tables all by itself. It reinvented support structures such as the cantilever and the triangle without prior knowledge of them. Credit card companies use a computer program called The Falcon to detect card fraud. The Falcon works by constantly updating a profile of how customers use their credit cards. It then looks for uncharacteristic patterns of credit card use in the data. A robotic head built by a Scottish robotics company can determine a woman"s attractiveness. It works by examining faces to determine how "feminine" or "masculine" they are. It doesn"t work in reverse because men"s appeal is supposedly not based as much on looks. Perhaps jokingly, researchers say it could be put to use as an artificial receptionist. Robots designed for the consumer market and employing very basic forms of AI have become increasingly popular in recent years. Sony"s Aibo robot dog behaves like a puppy when it is first activated. But it "learns" new behavior as it spends more time with its human owner. A software program called FACES could stop mid-air collisions between planes. When tested in a flight simulator (模拟器), the software prevented a pile-up between 35 planes sharing airspace.
J. Over the coming century, breakthroughs in nanotechnology, the science of ultra-small machines constructed at the molecular level, may help us build more sophisticated machines that are more compact. We may also see breakthroughs from scientists who are experimenting with connecting biological cells to silicon circuits—a phenomenon called wetware.In the early 1990s, the research of artificial intelligence had been replaced by the development of smaller, independent robots.

Are we ready for the library of the future
A. Librarians today will tell you their job is not so much to take care of books but to give people access to information in all forms. Since librarians, like so many people, believe that the entire universe of commerce, communication and information is moving to digital form, they are on a reform to give people access to the Internet—to prevent them from becoming second-class citizens in an all-digital world. Something funny happened on the road to the digital library of the future, though. Far from becoming keepers of the keys to the Grand Database of Universal Knowledge, today"s librarians are increasingly finding themselves in an unexpected, overloaded role: They have become the general public"s last-resort providers of tech support.
B. It wasn"t supposed to be this way. Today"s libraries offer a variety of media and social-cultural events—they are "blended libraries," to use a term created by Kathleen Imhoff, assistant director of the Broward County Library of Fort Lauderdale, Florida. At the newly remodeled San Francisco Public Library, the computers are prominently displayed in the center of the library building while the books are all but hidden on the periphery (外围). Imhoff"s own library has word processing and other types of software for visitors to use, Internet access, audio CDs, videotapes, concerts, lectures, books and periodicals in three forms (print, microfiche and digital). Many libraries have found that this kind of "blending" is hugely popular in their communities, and librarians explain the changes in their institutions" roles by pointing to the public demand for these new services. But other trends are at work, too.
C. For some time, libraries have been automating their back-end, behind-the-desk functions for reasons of cost and convenience, just like any other business. Now, the computers have moved out from behind librarians" desks and onto the floor where the visitors are. This means that, suddenly, library-goers will have to know how to use those computers. This sounds reasonable enough until you take a close look. Unfortunately, the same technology that cuts costs and relieves librarians of work behind the scenes increases it for the public—and for the librarians at the front desk who have to help the public figure out how to use the technology. The unhappy result: People are simply not finding the information they seek.
D. If you are just coming to the library to read a book for pleasure and you know what a card catalog is and you have some basic computer skills, then you are going to be OK. But if you are trying to find some specific information—say, whether software in the classroom helps kids learn better or the causes of lung cancer or the basic procedure for doing a cost-benefit analysis of computer systems (three topics I have actually tried to look up in the San Francisco library)—then you"re in trouble.
E. To begin with, library visitors must now be able to type, to use a mouse and a menu and to understand the various types of computer interfaces (terminal text, windows and browsers).

After I had been to the new San Francisco library three times, I started keeping a folder of instructions on how to do a keyword search, since I would forget between visits.
F. Probably 50% of the population has never used a computer, fewer know how to type and almost nobody knows anything about electronic databases or searching grammar.

But even at libraries where the staff has resisted becoming computer trainers, they are still forced to devote significant resources to the problem.

The librarians have neither the time nor the peculiar skill (nor the time to develop the skill) to teach it to them. At the reference desks, librarians try not to spend a lot of time teaching people the basics of how to use the computer, but sometimes it"s unavoidable. "We try to get them started," says business librarian John Kenney. "We let them do as much as they can on their own and they come get us. It"s certainly a big problem."
H. The San Francisco library offers classes on its own electronic catalog, commercial periodical indexes and the Internet twice a week as well as occasional lectures about the Internet. Although it seems odd to me that people now need to take a two-hour class before they can use the library, the classes are always full.

It could be used to put a human face to the artificial brains of the future.
I. A computer program developed at Brandeis University in Massachusetts has learnt how to design and build bridges, cranes and tables all by itself. It reinvented support structures such as the cantilever and the triangle without prior knowledge of them. Credit card companies use a computer program called The Falcon to detect card fraud. The Falcon works by constantly updating a profile of how customers use their credit cards. It then looks for uncharacteristic patterns of credit card use in the data. A robotic head built by a Scottish robotics company can determine a woman"s attractiveness. It works by examining faces to determine how "feminine" or "masculine" they are. It doesn"t work in reverse because men"s appeal is supposedly not based as much on looks. Perhaps jokingly, researchers say it could be put to use as an artificial receptionist. Robots designed for the consumer market and employing very basic forms of AI have become increasingly popular in recent years. Sony"s Aibo robot dog behaves like a puppy when it is first activated. But it "learns" new behavior as it spends more time with its human owner. A software program called FACES could stop mid-air collisions between planes. When tested in a flight simulator (模拟器), the software prevented a pile-up between 35 planes sharing airspace.
J. Over the coming century, breakthroughs in nanotechnology, the science of ultra-small machines constructed at the molecular level, may help us build more sophisticated machines that are more compact. We may also see breakthroughs from scientists who are experimenting with connecting biological cells to silicon circuits—a phenomenon called wetware.Some scientists believed that the processing power of ASCI Purple is still far behind from that of human beings.

Are we ready for the library of the future
A. Librarians today will tell you their job is not so much to take care of books but to give people access to information in all forms. Since librarians, like so many people, believe that the entire universe of commerce, communication and information is moving to digital form, they are on a reform to give people access to the Internet—to prevent them from becoming second-class citizens in an all-digital world. Something funny happened on the road to the digital library of the future, though. Far from becoming keepers of the keys to the Grand Database of Universal Knowledge, today"s librarians are increasingly finding themselves in an unexpected, overloaded role: They have become the general public"s last-resort providers of tech support.
B. It wasn"t supposed to be this way. Today"s libraries offer a variety of media and social-cultural events—they are "blended libraries," to use a term created by Kathleen Imhoff, assistant director of the Broward County Library of Fort Lauderdale, Florida. At the newly remodeled San Francisco Public Library, the computers are prominently displayed in the center of the library building while the books are all but hidden on the periphery (外围). Imhoff"s own library has word processing and other types of software for visitors to use, Internet access, audio CDs, videotapes, concerts, lectures, books and periodicals in three forms (print, microfiche and digital). Many libraries have found that this kind of "blending" is hugely popular in their communities, and librarians explain the changes in their institutions" roles by pointing to the public demand for these new services. But other trends are at work, too.
C. For some time, libraries have been automating their back-end, behind-the-desk functions for reasons of cost and convenience, just like any other business. Now, the computers have moved out from behind librarians" desks and onto the floor where the visitors are. This means that, suddenly, library-goers will have to know how to use those computers. This sounds reasonable enough until you take a close look. Unfortunately, the same technology that cuts costs and relieves librarians of work behind the scenes increases it for the public—and for the librarians at the front desk who have to help the public figure out how to use the technology. The unhappy result: People are simply not finding the information they seek.
D. If you are just coming to the library to read a book for pleasure and you know what a card catalog is and you have some basic computer skills, then you are going to be OK. But if you are trying to find some specific information—say, whether software in the classroom helps kids learn better or the causes of lung cancer or the basic procedure for doing a cost-benefit analysis of computer systems (three topics I have actually tried to look up in the San Francisco library)—then you"re in trouble.
E. To begin with, library visitors must now be able to type, to use a mouse and a menu and to understand the various types of computer interfaces (terminal text, windows and browsers). It"s also nice if you know 17 different ways to quit a program, which electronic databases you should look in for what kinds of information, the grammar necessary to define your search and the Library of Congress" controlled vocabulary. After I had been to the new San Francisco library three times, I started keeping a folder of instructions on how to do a keyword search, since I would forget between visits.
F. Probably 50% of the population has never used a computer, fewer know how to type and almost nobody knows anything about electronic databases or searching grammar. As a result, the public library is now engaged in a massive attempt to teach computer literacy to the entire country. Some librarians compare it to the adult literacy programs the library also sponsors, but this is on a far larger scale—and less closely tied to the library"s traditional mission. The response at each library system has been different. Some libraries actually give courses in word processing, accounting program and so on. But even at libraries where the staff has resisted becoming computer trainers, they are still forced to devote significant resources to the problem.
G. Such has been the case in San Francisco, where people with disabilities can sign up to use the voice-recognition program Dragon Dictate—but only if they can prove they already know how to use the software. The librarians have neither the time nor the peculiar skill (nor the time to develop the skill) to teach it to them. At the reference desks, librarians try not to spend a lot of time teaching people the basics of how to use the computer, but sometimes it"s unavoidable. "We try to get them started," says business librarian John Kenney. "We let them do as much as they can on their own and they come get us. It"s certainly a big problem."
H. The San Francisco library offers classes on its own electronic catalog, commercial periodical indexes and the Internet twice a week as well as occasional lectures about the Internet. Although it seems odd to me that people now need to take a two-hour class before they can use the library, the classes are always full. But despite the excellent teachers, two hours is simply not enough to meet the needs of the students, many of whom have never used a computer before in their lives and many of whom simply can"t type. When I took the class one Tuesday, the man sitting next to me said he has used the library"s computer catalog many times, but he keeps making typing mistakes without knowing it. This unexpectedly throws him into the wrong screens and he doesn"t know how to get back. On the floor, he repeatedly has to ask a librarian for help.
I. "Providing technology does not mean people can use the technology," says Marc Webb, a San Francisco librarian and one of the teachers. "Half the voters are still trying to read English." The library has also had to deal with the practical difficulties of making its catalog accessible via the Internet, a new service many libraries are starting to offer. "It"s absolutely overwhelming," Webb says. "Everyone is getting to us with multiple transports, they"re all using different software, they have Winsock or Telnet set up differently, and suddenly the library is forced to become a hardware and software help desk. When you"re trying to tell someone over the telephone how to set up Winsock through AOL when this is the first time they"ve ever used a computer, it"s very difficult."Blended libraries are hugely popular in communities at the present time.

Here comes the e-book revolution
A. At what temperature do electronic books catch fire We"re going to find out sometime this year. E-book sales are about to ignite. On Monday, Amazon.com is expected to unveil a new version of its Kindle reader. It will probably be a lot better and a little cheaper than the first version. But the real news already broke this week: A company spokesman announced that Amazon plans to offer Kindle books on Ceil Phones. This news countered Google"s announcement that the 1.5 million public domain books available on its Google Book Search offering will soon be available (free, of course) via a new Cell Phone application.
B. I believe that Cell Phones will quickly outpace the dedicated e-book readers, including the Kindle, as the platform of choice for e-book readers. Leading the pack The iPhone, ironically. It"s worth noting that Amazon.com sold more Kindles (at least 500,000) in its first year of sales than Apple sold iPods in its first year (378,000). Apple may not understand the value of e-books, but iPhone users will embrace them anyway. The reason is simple: The iPhone has a huge, high-quality screen. And its user base includes millions of people who love to do everything on their iPhones, including reading, which they"re already doing with online content. I (and others) have been predicting for some time that Apple will ship a killer tablet at some point. This device, I believe, will have the iPhone user interface and a super high-quality screen. It will be ideal for reading e-books as well.
C. Just because e-books are available on better (the new Kindle) and more (all Cell Phones) devices doesn"t mean people will read them. But mark my words, read them they will. Six trends will conspire (共同促成) over the next year to drive e-book reading to levels that will surprise just about everybody.
D. The economy is in the tank, and people are looking to cut costs any way they can. An Amazon Kindle pays for itself after the purchase of 20 or 30 books, then starts paying dividends. You save big on books, magazines and newspapers. These savings will grow even more attractive as the recession deepens.
E. Interest in protecting the environment just keeps growing and growing. The idea of getting a daily newspaper or a weekly or monthly magazine on paper seems incredibly wasteful to the point of decadence. Environmental consciousness will drive e-book acceptance.
F. The book publishing industry is one of the most backward, musty, out-of-date businesses in our economy. While every other kind of information moves at the speed of light, the process of publishing a book is like something from the Middle Ages. For authors, it can take months to even find a literary agent willing to represent their work. Then the agent takes months to find a publisher. Then it takes ages for the publishing company to get the book out there. People are already circumventing (设法回避) all this by self-publishing. The self-publishing industry is the only area of paper-book publishing that"s thriving right now. Soon enough, a huge number of authors are finally going to get fed up with the publishing industry and just self-publish electronically. They"ll hire their own freelance editors, and do the marketing themselves. The publication of a finished manuscript will take minutes, rather than months.
G. Old-school thinkers in the publishing industry will lament (悲叹) the slap-dash nature of self-published e-books, and sniff" that books are no longer published with the quality and care that they used to. (Never mind that book publishers abandoned high standards years ago in previous cost-cutting initiatives.) The world will pass them by as the book industry undergoes the same transition that happened with the media and blogs. First, the media didn"t understand blogs. Then they invalidated them. Then they accepted them. And now blogs are where the credibility is. Every columnist and reporter has a blog, and now major TV news programs are built around the opinions of bloggers. A similar transformation will take place about the credibility of serf-published and electronic books.
H. Like the move from silent pictures to "talkies," the transition to electronic publishing will prove fatal to laggards. Those aggressively pursuing and developing e-books will rise to take control of the publishing industry. Part of this revolution will happen in e-book marketing. The new generation of e-book publishers will leverage social media, contextual advertising and other innovations. For anyone who spends time online, specific e-book titles will increasingly be advertised and marketed and integrated into other content. E-books, now mostly invisible, will soon be everywhere.
I. The shift from print to electronic will change the nature of the book itself. Many books will be shorter. They"ll be more timely and culturally relevant. They"ll be more colorfully and engagingly written. And they"ll go after young readers like nothing before. As in Japan, this will spark a new cultural phenomenon of young people not just reading, but also writing novels and other book types on their mobile devices. The idea that "people don"t read anymore," especially young people, will be revealed as false. Young people today read more, and write a lot more, than any generation in history. To date, they"ve been unexcited about books, magazines and newspapers because they grew up with social networking and social media. Once books are electronic, relevant and social, too, they"ll start reading and writing books like crazy.
J. And, finally, the newspaper industry is dying. The old method of physically delivering blog entries on dead tree pulp is out-of-date. It"s very simple. Newspapers that embrace e-books will survive. Those that don"t, won"t. If you"d like to get a stark view of the relative economics of electronic vs. paper newspapers, check out a blog post on the Silicon Valley Insider . The blog did the math and determined that the New York Times could buy every single subscriber an Amazon Kindle e-book reader, and it would still cost them half as much as it will cost them to send paper newspapers for just one year. After decades of false starts, the e-book revolution is finally upon us. By this time next year, e-books will be totally mainstream.The publishing industry will soon be taken control by those who aggressively pursue and develop e-books.

Artificial Intelligence(AI)
A. We often don"t notice it, but artificial intelligence (AI) is all around us. It is present in computer games, in the cruise control in our cars and the servers that route our email. In June 2002, a robot called Gaak gave an alarming demonstration of its independence. It made a dash for freedom from an exhibit at the Magna science centre in Rotherham. Gaak crept along a barrier until it found a gap and squeezed through. Having left the building, it reached Magna"s exit by the M1 motorway before it was discovered.
B. So, can a machine behave like a person This question underlies artificial intelligence, the study of intelligent behavior in machines. In the 1980s, AI research focused on creating machines that could solve problems and reason like humans. One of the most difficult problems in artificial intelligence is that of consciousness. A consciousness gives us feelings and makes us aware of our own existence. But scientists have found it difficult getting robots to carry out even the simplest of cognitive tasks. Creating a self-aware robot with real feelings is a significant challenge faced by scientists hoping to imitate human intelligence in a machine. Since the early 1990s, researchers have concentrated on developing smaller, independent robots instead of trying to recreate human intelligence. The model for many of these machines is insect intelligence, which is—in its own way—very sophisticated.
C. When it is completed in late 2004, the world"s most powerful computer will be ASCI Purple, built by IBM. It is expected to carry out 100 trillion operations per second (or 100 teraflops). A super-computer with double this processing power is expected within the next two years. It is being built to replace ASCI White—formerly the world"s most powerful computer—which occupies a space the size of two basketball courts at the Lawrence Livermore National Laboratory in Livermore, California. A spokesman for IBM said that ASCI Purple was approaching the processing power of the human brain. But some scientists believe our brains can carry out around 10,000 trillion operations per second. HAL, the supercomputer that rebels against its human handlers in the film 2001: A Space Odyssey (1968), is a bold reference to IBM. The letters H, A and L, precede I, B and M in the alphabet.
D. In 1950, mathematician Alan Turing devised a test to identify whether a machine displayed intelligence. In the Turing Test, two people (A and B) sit in a closed room, while an interrogator (询问者) (C) sits outside. Person A tries to fool the interrogator about their gender, while person B tries to assist the interrogator in their identification. Turing suggested a machine take the place of person A. If the machine consistently fooled the human interrogator, it was likely to be intelligent.
E. The possible dangers posed by intelligent machines have inspired countless science fiction films. In The Terminator (1984), a computer network attacks the human race in order to achieve control. This network then manufactures intelligent robots called "Terminators" which it programs to destroy human survivors. In The Matrix (1999) and The Matrix Reloaded (2003), a machine enslaves humanity, using people as batteries to power its mainframe. Steven Spielberg"s AI: Artificial Intelligence (2002) paints a more sympathetic view of artificial life, depicting sensitive robots that are abused by brutal, selfish human masters.
F. One place where artificial intelligence has found a natural home is in the development of computer games. AI in computer games is becoming increasingly sophisticated as consumer appetites for better, faster, more challenging games grows. In games, AI is often present in the opponents you play against, or in allies or other team members.
G. In 1997, then world chess champion Garry Kasparov played against IBM"s Deep Blue supercomputer—and lost. After six games, the mighty Kasparov lost 2.5 to 3.5 to the silicon upstart. In February 2003, Kasparov saved some credibility for humanity by drawing against the Israeli-built supercomputer Deep Junior. Kasparov went on to draw 2-2 against US company X3D Technologies" supercomputer X3D Fritz in November 2003, proving that the human brain can keep up with the latest developments in computing (at least in chess).
H. Despite these entertaining applications, the original point of AI research was to create machines that could understand us. At the Massachusetts Institute of Technology (MIT), scientists have designed a robot called Kismet that can have realistic conversations with people. Kismet is capable of seven different facial expressions and can vary the tone of its voice. It also adjusts its gaze and the direction of its head towards the person it is speaking to. Scientists at HP have designed an electronic DJ. The "hpDJ" selects beats and baselines from its memory bank and mixes them. Its makers say it could be made to react to the mood of clubbers. At the University of Texas, Dallas, researchers have designed a lifelike human face capable of 28 facial movements, including smiling, sneering, furrowing its brow and arching its eyebrows. It could be used to put a human face to the artificial brains of the future.
I. A computer program developed at Brandeis University in Massachusetts has learnt how to design and build bridges, cranes and tables all by itself. It reinvented support structures such as the cantilever and the triangle without prior knowledge of them. Credit card companies use a computer program called The Falcon to detect card fraud. The Falcon works by constantly updating a profile of how customers use their credit cards. It then looks for uncharacteristic patterns of credit card use in the data. A robotic head built by a Scottish robotics company can determine a woman"s attractiveness. It works by examining faces to determine how "feminine" or "masculine" they are.
