The struggle against malnutrition and
hunger is as old as man himself, and never across the face of our planet has
outcome been more in doubt. Malnutrition caused much suffering to an estimated
400 million to 1.5 billion of the world’s poor. Even in the wealthy US poverty
means undernourishment for an estimated ten to twenty million. Hardest hit are
children, whose growing bodies demand two and a half times more protein, pound
for pound, than those of adults. Nutrition experts estimate that 70 percent of
the children in low-income countries are affected.
Badly shaped
bodies tell the tragic story of malnutrition. Medical science identifies two
major types of malnutrition which usually occur in combination. The first,
kwashiorkor (恶性营养不良), is typified by the bloated look. The opposite of what we
associate with starvation. Accumulated fluids pushing against wasted muscles
account for the plumpness of hands, feet, belly, and face. Lean shoulders reveal
striking thinness. Caused by an acute lack of protein kwashiorkor can bring
brain damage, anemia, diarrhea, irritability, apathy, and loss of
appetite.
On the other hand, stick limbs, a bloated belly, wide
eyes, and the stretched skin face of an old person mark victims of marasmus, a
word taken from the Greek "to waste away". Lacking calories as well as protein,
sufferers may weigh only half as much as normal. With fat gone, the skin hangs
in wrinkles or draws tight over bones. With marasmus comes anemia, diarrhea,
dehydration, and a very hungry appetite. Children, whose growing bodies require
large amounts of protein, have to suffer in greatest numbers, but perhaps only
three percent of all child victims suffer the extreme stages
described.
Scientists are doing best to develop new weapons
against malnutrition and starvation. But two thirds of the human population of
3.9 billion live in the poorest countries which also have the highest birth
rates. Thus, of the 74 million people added to the population each year, four
out of five will be born in a country unable to supply its people’s nutritional
needs.
A．suffer more than adults because they eat less food
B．suffer less than adults because they are physically smaller
C．are affected more than adults since their food contains less protein
D．are affected more than adults simply because they need more protein

For years there have been endless
articles stating that scientists are on the verge of achieving artificial
intelligence, that it is just around the corner. The truth is that it may be
just around the corner, but they haven’t yet found the right clock.
Artificial intelligence aims to build machines that can think. One
immediate problem is to define thought, which is harder than you might think.
The specialists in the field of artificial intelligence complain, with some
justification, that anything that their machines do is dismissed as not being
thought. For example, computers can now play very, very good chess. They can’t
beat the greatest players in the world, but they can beat just about anybody
else. If a human being played chess at this level, he or she would certainly be
considered smart. Why not a machine The answer is that the machine doesn’t do
anything clever in playing chess. It uses its blinding speed to do a brute-force
search of all possible moves for several moves ahead, evaluates the outcomes and
picks the best. Humans don’t play chess that way. They see patterns, which
computers don’t.
This wooden approach to thought characterizes
machine intelligence. Computers have no judgment, no flexibility, no common
sense. So-called expert systems, one of the hottest areas in artificial
intelligence, aim to mimic the reasoning processes of human experts in a limited
field, such as medical diagnosis or weather forecasting. There may be limited
commercial applications for this sort of thing, but there is no way to make a
machine think about anything under the sun, which a teenager can do. The
hallmark of artificial intelligence to date is that if a problem is severely
restricted, a machine can achieve limited success. But when the problem is
expanded to a realistic one, computers fall flat on their display screens. For
example, machines can understand a few words spoken individually by a speaker
that they have been trained to hear. They cannot understand continuous speech
using an unlimited vocabulary spoken by just any
speaker.
A．the writer thinks that the specialists’ complaints have some reasons
B．anything that the computer does can be regarded as thought
C．it is not very difficult to define thought
D．computers play chess in exactly the same way as humans
