An office is the "brain" of a business. In an office, figures, lists and information are compiled which tell the managers or heads of the business what is happening in their shops or factories. These figures guide the managers【51】telling them what has happened and what is happening.
Information comes into an office in all sorts of【52】but the main items of information come
in regularly. It is part of the job of the clerks to collect and classify that information and to put it into a form. that is easily interpreted and understood. Offices collect information, then they【53】it.
This work of collection is common in an office from the sorting of mail every morning to the accountant's work in finding【54】the final figure for year's profit.【55】always requires the arrangement of the same kind of information, often into lists or columns. For this work, correctness, accuracy and speed, as in all office work, are essential.
There is no value,【56】, in collecting the figures【57】mean nothing.【58】are guides which should help us【59】decisions. The interpretation of information and of tables should tell us where success or【60】lies, where profit can be had and where【61】occur. On this kind of information and from the known figures, a choice is【62】and a series of such choices may make a policy.
A firm which has three factories may find,【63】. instance, from its figures, that one factory is losing money and a choice may lie between either a change of manager, a cut in production, an increase in production【64】closure of the factory. Whichever one of these decisions is taken becomes the policy. It is clear【65】a decision leading to a policy can only be as good【66】 the information【67】which it is based.
Consequently there is a constant search【68】more and more exact information. Managers will want to have all the necessary facts【69】they can make the best decision and it is normal for【70】to seek for more and more information.

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 can be programmed into the computer's brain just as nature programmed them into our human brains as a part of the equipment for survival.
Computers match people in some roles, and when fast decisions are needed in a crisis, they often surpass them. Having evolved when the pace of life was slower, the human brain has an inherent defect that prevents it from absorbing several streams of information simultaneously and acting on them quickly. Throw too many things at the brain at one time and it freezes up.
We are still in control, but the capabilities are increasing at a fantastic rate, while raw human intelligence is changing slowly, if at all. Computer power has increased ten times every eight years since 1946. In the 1990s, when the sixth generation appears, the reasoning power of an intelligence built out of silicon will begin to match that of the human brain.
That does not mean the evolution of intelligence has ended on the earth. Judging by the past, we can expect that a new species out of man, surpassing his achievements as he has surpassed those of his predecessor. Only a carbon chemistry would assume that the new species must be man's flesh-and-blood descendants. The new kind of intelligent life is more likely to be made of silicon.
Today, we cannot see computer as a new form. of life in terms of ______ .
A．quickness of decision making
B．drives and sentiment
C．development of reasoning power
D．information storage
Approximately 85 percent of people prefer their right hand, which is controlled by the left hemisphere of the brain. One theorized benefit of locating a particular function in one hemisphere is that it frees the other to deal with different tasks. But that idea does not explain why. population-wide trends for handedness exist in the first place.
Moreover, evidence gleaned in recent years has overturned the long-held belief that human handedness is a unique by-product of brain specialization attributable to language. A suite of studies has revealed brain lateralization in species from fish to primates(灵长类). Last August, for instance, scientists discovered that in the wild, chimpanzees show hand preferences.
The presence of lateralization throughout the animal kingdom suggests some benefit from it, contend neuroscientists Giorgio Vallortigara of the University of Trieste and Lesley Rogers of the University of New England in Australia. Also, last August, in the journal Behavioral and Brain Sciences, the two presented evidence to support their idea that social constraints force individuals toward asymmetry in the same direction. They noted, for example, that baby chickens attack more readily when a threat appears on their left. And Rogers has found that chicks with more asymmetrical brains form. more stable social groups: perhaps by approaching each other on the right, she hypothesizes, the chicks fight one another less and are more likely to notice predators.
Lateralization seems to confer an advantage for some fish as well. In certain species, the majority tend to swim left when a predator attacks, whereas other species head right. The potential benefits of such patterns may not seem intuitive: a predator could learn that attacking a fish on one particular side is more effective. But Vallortigara and Rogers's idea fits with the conventional explanation of why fish school at all. When threatened, fish turning in the same direction have a greater chance of survival than if they scatter to become a darting swarm of head-butting fish.
Nevertheless, the bird and fish. data do not explain human handedness.
"The issue then becomes: maybe this lateralization long predates the rise of the mammals," speculates Robin Dunbar ,an evolutionary psychologist at the University of Liverpool in England.
Fish school suggests that ______.
A．it was a necessary evolutionary process
B．it has something to do with human right-handedness
C．they need to coordinate with other fish
D．their brain function is unique

What do you suppose was the attitude of Dr. Samuel Johnson towards ladies preaching？

D．He encouraged ladies to preach.
听力原文：W: A great day, isn't it？
M: I guess so. But I feel awful because I watched TV until after midnight last night.
W: After midnight! Did you watch so late because you were bored？ I usually watch TV only ff I have nothing better to do.
M: Bored？ No, I was upset because I left my meal tickets in the cafeteria.
W: That worth more than fifty dollars. So, did watching TV make you feel better？
M: A bit. But after I turned the TV off, I just felt disgusted with myself for wasting so much time.
W: I've had that feeling before.
M: I had intended to watch just one program, but somehow I couldn't make myself switch off the TV.
W: Actually, I've read that there's a scientific explanation for that. It seems that there's a part of the brain that processes complex information, but that part becomes less active while watching TV.
M: That's certainly how I felt last night--like my brain wasn't very active.
W: That's not the worst of it. If you watch TV a lot, or for a long time, that part of the brain--the part that processes complex information, shows lowered activity and you become more and more passive.
M: That's incredible.
W: Next time you feel upset, you should go swimming. That's what I do, and it always makes me feel better.
M: I suppose. Now I've got to go to the cafeteria and get some more meal tickets.

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.
