Part I. Reading Comprehension (40%)

Directions: There are 4 reading passages in this section. Each passage is followed by some questions. For each question there are four suggested answers

marked A, B, C and D. Choose the best answer to each question. Passage 1

Every country tends to accept its own way of life as being normal one and to praise or criticize others as they are similar to or different from it. And unfortunately, our picture of the people and the way of life of other countries is often a distorted one. Here is a great argument in favor of traveling abroad and learning foreign languages. It is only by traveling or living in a country and getting to know its inhabitants and their language that one can find out what a country and its people are like. And how different the knowledge one gains this way frequently turns out to be from the second-hand information gathered from other sources! How often we find that the foreigners whom we thought to be such different people from ourselves are not very different after all.

Differences between peoples do, of course, exist and, one hopes, will always continue to exist. The world will be a dull place indeed when all the different nationalities behave exactly alike, and some people might say that we are rapidly approaching this state of affairs. With almost the whole of Western Europe belonging to the European Economic Community (EEC) and the increasing standardization this brings about, plus the much greater rapidity and ease of travel, there might seem some truth in this—at least as far as Europe is concerned. However this may be, at lest the greater ease of travel today has revealed to more people than ever before that the Englishman or Frenchman or German is not some different animal from themselves.

A. advantages of the EEC

B. reading books about other countries is the safest way of understanding their

peoples

C. there are more similarities than differences among different people

3. Some people think that European peoples are identifying themselves with each

other because of the following EXCEPT _____.

A. the establishment of the EEC

4. The clause “However this may be” suggests that ____.

A. the author is going to introduce a new idea

B. the author is about to avoid any conclusion

C. the author is about to give up his own point of view

D. the author will stick to his own point of view

5.The passage seems to attach importance to ____.

A. the greater ease of travel nowadays than before

D. the differences between European peoples and other nations

Passage 2

The more time scientists spend designing computers the more they marvel at the human brain. Tasks that baffle（难住）the most advanced supercomputer—recognizing a face, reading a handwritten note—are child’s play for the 3-pound organ. Most important, unlike any conventional computer, the brain can learn from its mistakes. Researchers have tried for years to program computers to imitate the brain’s abilities, but without success. Now a growing number of designers believe they have the answer: if a computer is to function more like a person and less like an over-grown calculator it must be built more like a brain, which distributes information across a vast interconnected web of nerve cells, or neurons.

Conventional computers function by following a chainlike sequence of detailed instructions. Although very fast, their processors can perform only one task at a time. This approach works best in solving problems that can be broken down into simpler logical pieces. The processors in a neural-network computer, by contrast, form a network much like the nerve cells in the brain. Since these artificial neurons are interconnected, they can share information and perform tasks at the same time. This two-dimensional approach works best at recognizing patterns.

Instead of programming a neural-network computer to make decisions, its maker trains it to recognize patterns in any solution to a problem by repeatedly feeding examples to the machine.

Neural networks come in all shapes and sizes. Until now most existed as software simulations（模拟品）because redesigning computer chips took a lot of time and money. By experimenting with different approaches through software rather than hardware, scientists have been able to avoid costly mistakes.

6. It can be inferred from the first paragraph that the most advanced supercomputer

____.

A. can recognize a face and read a handwritten note
