According to Ian Pearson, a futurologist, these are among the developments scheduled for the first few decades of the new millennium, when supercomputers will dramatically accelerate progress in all areas of life.
Pearson has 1 together the work of hundreds of researchers around the world to produce a unique millennium technology calendar that gives the latest dates when we can expect hundreds of key 2 and discoveries to take place. Some of the biggest developments will be in medicine, including an 3 life expectancy and dozens of artificial 4 coming into use between now and 2040.
Pearson also has 5 a breakthrough in computer-human links. "By linking directly to our nervous system, computers could pick up what we feel and, hopefully, simulate feeling too so that we can start to 6 full sensory environments, rather like the holidays in Total Recall or the Star Trek holodeck," he says.
But that, Pearson points out, is only the start of man-machine 7 : "It will be the beginning of the long process of integration that will ultimately lead to a fully electronic human before the end of the next century." Through his research, Pearson is able to put dates to most of the breakthroughs that can be predicted. However, there are still no 8 for when faster-than-light travel will be 9 , or when human cloning will be perfected, or when time travel will be possible.
But he does expect social problems as a result of technological advances.

Many theories concerning the causes of juvenile delinquency (crimes committed by young people) focus either on the individual or on society as the major contributing influence. Theories 11 on the individual suggest that children engage in criminal behavior because they were not sufficiently 12 for previous misdeeds or that they have learned criminal behavior through interaction with others. Theories focusing on the role of society suggest that children commit crimes in 13 to their failure to rise above their socioeconomic status, or as a rejection of middle-class values.
Most theories of juvenile delinquency have focused on children from disadvantaged families, 14 the fact that children from wealthy homes also commit crimes. The latter may commit crimes for lack of adequate parental control. All theories, however, are tentative and are 15 to criticism.
Changes in the social structure may indirectly 16 juvenile crime rates. For example, changes in the economy that lead to fewer job opportunities for youth and rising unemployment in general make gainful employment increasingly difficult to obtain. The resulting discontent may in 17 lead more youths into criminal behavior.
Families have also 18 changes these years. More families consist of one-parent households or two working parents; consequently, children are likely to have less supervision at home than was common in the traditional family pattern. This lack of parental supervision is thought to be a(n) 19 on juvenile crime rates.
Other 20 causes of offensive acts include frustration or failure in school, the increased availability of drugs and alcohol, and the growing incidence of child abuse and child neglect. All these conditions tend to increase the probability of a child committing a criminal act, although a direct causal relationship has not yet been established.

We live in a society where there is a lot of talk about science, but I would say that there are not 5 percent of the people who are equipped with school, including college, to understand scientific 31 . We are more ignorant of science than people with 32 education in Western Europe.
There are a lot of kids who know everything about computers—how to build them, how to take them 33 , and how to write programs for games. But if you ask them to explain the principles of physics that have gone into 34 the computer, they don"t have the 35 idea. The failure to understand science leads to such things as the neglect of human creative power. It also gives rise to the 36 of the distinction between science and technology. Lots of people don"t 37 between the two. Science is the production of new knowledge that can be applied or not, and technology is the application of knowledge to the production of some products, machinery or the like. The two are really different, and people who have the faculty of one very 38 have that for the other. Science in itself is 39 , more or less. But as soon as it can provide technology, it"s not 40 harmless. No society has yet learned to forecast the consequences of new technology, which can be enormous.

Almost every new innovation goes through three phases. When 21 introduced into the market, the process of 22 is slow. The early models are expensive and hard to use, and perhaps even unsafe. The economic 23 is relatively small. The second phase is the explosive one, 24 the innovation is rapidly adopted by a large number of people. It gets cheaper and easier to use and becomes something familiar. And then in the third stage, diffusion of the innovation slows down again, as it permeates out across the economy.
During the explosive phase, whole new industries spring up to produce the new product or innovation, and to 25 it. For example, during the 1920s, there was a dramatic acceleration in auto production, from 1.9 million in 1920 to 4.5 million in 1929. This 26 was accompanied by all sorts of other essential activities necessary for an auto-based nation: Roads had to be built for the cars to run 27 ; refineries and oil wells, to provide the gasoline; and garages, to repair them. The same pattern is 28 repeated again and again with innovations. The construction of the electrical system required an enormous early investment in generation and distribution 29 . The introduction of the radio was followed by a buying spree (无节制的狂热行为) by Americans that quickly brought radios into almost half of all household by 1930, up from 30 none in 1924.

Almost every new innovation goes through three phases. When 21 introduced into the market, the process of 22 is slow. The early models are expensive and hard to use, and perhaps even unsafe. The economic 23 is relatively small. The second phase is the explosive one, 24 the innovation is rapidly adopted by a large number of people. It gets cheaper and easier to use and becomes something familiar. And then in the third stage, diffusion of the innovation slows down again, as it permeates out across the economy.
During the explosive phase, whole new industries spring up to produce the new product or innovation, and to 25 it. For example, during the 1920s, there was a dramatic acceleration in auto production, from 1.9 million in 1920 to 4.5 million in 1929. This 26 was accompanied by all sorts of other essential activities necessary for an auto-based nation: Roads had to be built for the cars to run 27 ; refineries and oil wells, to provide the gasoline; and garages, to repair them. The same pattern is 28 repeated again and again with innovations. The construction of the electrical system required an enormous early investment in generation and distribution 29 . The introduction of the radio was followed by a buying spree (无节制的狂热行为) by Americans that quickly brought radios into almost half of all household by 1930, up from 30 none in 1924.

According to Ian Pearson, a futurologist, these are among the developments scheduled for the first few decades of the new millennium, when supercomputers will dramatically accelerate progress in all areas of life.
Pearson has 1 together the work of hundreds of researchers around the world to produce a unique millennium technology calendar that gives the latest dates when we can expect hundreds of key 2 and discoveries to take place. Some of the biggest developments will be in medicine, including an 3 life expectancy and dozens of artificial 4 coming into use between now and 2040.
Pearson also has 5 a breakthrough in computer-human links. "By linking directly to our nervous system, computers could pick up what we feel and, hopefully, simulate feeling too so that we can start to 6 full sensory environments, rather like the holidays in Total Recall or the Star Trek holodeck," he says.
But that, Pearson points out, is only the start of man-machine 7 : "It will be the beginning of the long process of integration that will ultimately lead to a fully electronic human before the end of the next century."

Many theories concerning the causes of juvenile delinquency (crimes committed by young people) focus either on the individual or on society as the major contributing influence. Theories 11 on the individual suggest that children engage in criminal behavior because they were not sufficiently 12 for previous misdeeds or that they have learned criminal behavior through interaction with others. Theories focusing on the role of society suggest that children commit crimes in 13 to their failure to rise above their socioeconomic status, or as a rejection of middle-class values.
Most theories of juvenile delinquency have focused on children from disadvantaged families, 14 the fact that children from wealthy homes also commit crimes. The latter may commit crimes for lack of adequate parental control. All theories, however, are tentative and are 15 to criticism.
Changes in the social structure may indirectly 16 juvenile crime rates. For example, changes in the economy that lead to fewer job opportunities for youth and rising unemployment in general make gainful employment increasingly difficult to obtain. The resulting discontent may in 17 lead more youths into criminal behavior.
Families have also 18 changes these years. More families consist of one-parent households or two working parents; consequently, children are likely to have less supervision at home than was common in the traditional family pattern. This lack of parental supervision is thought to be a(n) 19 on juvenile crime rates.
Other 20 causes of offensive acts include frustration or failure in school, the increased availability of drugs and alcohol, and the growing incidence of child abuse and child neglect. All these conditions tend to increase the probability of a child committing a criminal act, although a direct causal relationship has not yet been established.

Many theories concerning the causes of juvenile delinquency (crimes committed by young people) focus either on the individual or on society as the major contributing influence. Theories 11 on the individual suggest that children engage in criminal behavior because they were not sufficiently 12 for previous misdeeds or that they have learned criminal behavior through interaction with others. Theories focusing on the role of society suggest that children commit crimes in 13 to their failure to rise above their socioeconomic status, or as a rejection of middle-class values.
Most theories of juvenile delinquency have focused on children from disadvantaged families, 14 the fact that children from wealthy homes also commit crimes. The latter may commit crimes for lack of adequate parental control. All theories, however, are tentative and are 15 to criticism.
Changes in the social structure may indirectly 16 juvenile crime rates. For example, changes in the economy that lead to fewer job opportunities for youth and rising unemployment in general make gainful employment increasingly difficult to obtain. The resulting discontent may in 17 lead more youths into criminal behavior.
Families have also 18 changes these years. More families consist of one-parent households or two working parents; consequently, children are likely to have less supervision at home than was common in the traditional family pattern. This lack of parental supervision is thought to be a(n) 19 on juvenile crime rates.
Other 20 causes of offensive acts include frustration or failure in school, the increased availability of drugs and alcohol, and the growing incidence of child abuse and child neglect. All these conditions tend to increase the probability of a child committing a criminal act, although a direct causal relationship has not yet been established.

Almost every new innovation goes through three phases. When 21 introduced into the market, the process of 22 is slow. The early models are expensive and hard to use, and perhaps even unsafe. The economic 23 is relatively small. The second phase is the explosive one, 24 the innovation is rapidly adopted by a large number of people. It gets cheaper and easier to use and becomes something familiar. And then in the third stage, diffusion of the innovation slows down again, as it permeates out across the economy.
During the explosive phase, whole new industries spring up to produce the new product or innovation, and to 25 it. For example, during the 1920s, there was a dramatic acceleration in auto production, from 1.9 million in 1920 to 4.5 million in 1929. This 26 was accompanied by all sorts of other essential activities necessary for an auto-based nation: Roads had to be built for the cars to run 27 ; refineries and oil wells, to provide the gasoline; and garages, to repair them. The same pattern is 28 repeated again and again with innovations. The construction of the electrical system required an enormous early investment in generation and distribution 29 . The introduction of the radio was followed by a buying spree (无节制的狂热行为) by Americans that quickly brought radios into almost half of all household by 1930, up from 30 none in 1924.

We live in a society where there is a lot of talk about science, but I would say that there are not 5 percent of the people who are equipped with school, including college, to understand scientific 31 . We are more ignorant of science than people with 32 education in Western Europe.
There are a lot of kids who know everything about computers—how to build them, how to take them 33 , and how to write programs for games. But if you ask them to explain the principles of physics that have gone into 34 the computer, they don"t have the 35 idea. The failure to understand science leads to such things as the neglect of human creative power. It also gives rise to the 36 of the distinction between science and technology. Lots of people don"t 37 between the two. Science is the production of new knowledge that can be applied or not, and technology is the application of knowledge to the production of some products, machinery or the like. The two are really different, and people who have the faculty of one very 38 have that for the other. Science in itself is 39 , more or less. But as soon as it can provide technology, it"s not 40 harmless. No society has yet learned to forecast the consequences of new technology, which can be enormous. And, therefore, nobody can give a definite answer to the question whether science itself is safe.
A. reasoning B. seldom C. comparable D. differ
E. distinguish F. creating G. generally H. apart
I. faintest J. blurring K. harmless L. necessarily
M. tell N. down O. missing
