As Dr Samuel Johnson said in a
different era about ladies preaching, the surprising thing about computers is
not that they think less well than a man, but that they think at all. The early
electronic computer did not have much going for it except a marvelous memory and
some good math skills. But today the best models can be wired up to learn by
experience, follow an argument, ask proper questions and write poetry and music.
They can also carry on somewhat puzzling conversations.
Computers imitate life. As computers get more complex, the imitation gets
better. Finally, the line between the original and the copy becomes unclear. In
another 15 years or so, we will see the computer as a new form of
life.
The opinion seems ridiculous because, for one thing, computers
lack the drives and emotions of living creatures. But drives
A. quickness of decision making
B. drives and sentiment
C. development of reasoning power
D. information storage

Gene therapy and gene-based drugs are
two ways we could benefit from our growing mastery of genetic science. But there
will be others as well. Here is one of the remarkable therapies on the cutting
edge of genetic research that could make their way into mainstream medicine in
the coming years.
While it’s true that just about every cell in
the body has the instructions to make a complete human, most of those
instructions are inactivated, and with good reason: the last thing you want for
your brain cells is to start churning out stomach acid or your nose to turn into
a kidney. The only time cells truly have the potential to turn into any and all
body parts is very early in a pregnancy, when so-called stem cells haven’t begun
to specialize.
Yet this untapped potential could be a terrific
boon to medicine. Most diseases invol
A. aggravate moral issues of human cloning
B. bring great benefits to human beings
C. help scientists decode body instructions
D. involve employing surgical instruments

Although the dream of the home robot
has not died, robots have had their greatest impact in factories. Unimate, the
first industrial robot, went to work for General Motors in 1961. Even at a time
when computing power was costly, robots made excellent workers and proved that
machines controlled by computers could perform some tasks better than humans. In
addition, robots can work around the clock and never go on strike.
There are now about 800 000 industrial robots around the world, and orders
for new robots in the first half of 2007 were up a record 26% from the same
period in 2006, according to the United Nations Economic Commission for Europe
(UNECE). Demand is increasing as prices fall: a robot sold in 2007 cost less
than a fifth of an equivalent robot sold in 1990, for example. Today, in car
factories in Japan, Germa
A. the technology robots use is really advanced
B. robots greatly increase the efficiency in factories
C. robots are becoming economically available
D. most car factories around the world need robots

The Food and Drug Administration said
on Wednesday that it is trying to track down as many as 386 piglets that may
have been genetically engineered and wrongfully sold into the U.S. food
supply.
The focus of the FDA investigation is on pigs raised by
researchers at the University of Illinois in Urbana Champaign. They engineered
the animals with two genes: one is a cow gene that increases milk production in
the sow; the other, a synthetic gene, makes the milk easier for piglets to
digest. The goal was to raise bigger pigs faster.
There has been
no evidence that either genetically altered plants or animals actually trigger
human illness, but critics warn that potential side effects remain unknown.
University officials say their tests showed the piglets were not born with the
altered genes, but FDA roles require e
A. get pigs of larger size in a shorter time
B. make sows produce more milk
C. make cows produce more milk
D. make pigs grow more lean meat
