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 te

2、nds 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

3、 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 informat

4、ion 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 whe

5、n 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 grea

6、ter rapidity and ease of travel, there might seem some truth in thisat 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 themselv

7、es. 1. The passage is mostly concerned with the issue of _. A. advantages of the EECB. attitudes towards other countriesC. learning foreign languagesD. differences among people2. According to the author, _.A. our knowledge of other cultures are always wrongB. reading books about other countries is t

8、he safest way of understanding their peoplesC. there are more similarities than differences among different peopleD. there are more differences than similarities among different people3. Some people think that European peoples are identifying themselves with each other because of the following EXCEP

9、T _.A. the establishment of the EECB. the greater rapidity and ease of travelC. the increasing standardizationD. the rapid industrialization4. The clause “However this may be” suggests that _.A. the author is going to introduce a new ideaB. the author is about to avoid any conclusionC. the author is

10、 about to give up his own point of viewD. the author will stick to his own point of view5. The passage seems to attach importance to _. A. the greater ease of travel nowadays than before B. the uncontrollable tendency to identificationC. the similarities in terms of way of life between different cul

11、turesD. the differences between European peoples and other nations Passage 2The more time scientists spend designing computers the more they marvel at the human brain. Tasks that baffle（难住）the most advanced supercomputerrecognizing a face, reading a handwritten noteare childs play for the 3-pound or

12、gan. Most important, unlike any conventional computer, the brain can learn from its mistakes. Researchers have tried for years to program computers to imitate the brains abilities, but without success. Now a growing number of designers believe they have the answer: if a computer is to function more

13、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 pr

14、ocessors 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 intercon

15、nected, 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 exa

16、mples 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

17、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 noteB. can learn from its mistakesC. weigh only 3 poundsD. cannot distribute information across an interconnected web of nerve cells 7. What is NOT t

18、rue of a conventional computer? A. It must be programmed before it works.B. It can only solve one problem at a time. C. It is good at solving one problem at a time.D. It is trained to recognize patterns instead of making decisions.8. The main feature of a neural-network computer is that _.A. its pro

19、cessors act as an interconnected web of neutronsB. it is programmed to make decisionsC. its networks are of all shapes and sizes D. its neurons are artificial9. The expression “this two-dimensional approach” in the second paragraph refers to _. A. the conventional computer and the neural computerB.

20、making decisions and recognizing patternsC. sharing information and performing tasksD. the computer and the human brain10. Scientists use software rather than hardware in their experiments because _. A. it can avoid redesigning computer chipsB. it can save a lot of time and moneyC. it can avoid maki

21、ng mistakesD. it is more like the human brain Passage 3Teenagers who have done well in high school are usually confident and college-boundbut they are not the majority. Many of their peers have not yet learned necessary survival skills or experienced any feeling of achievement. They lack both the jo

22、b skills and the sophistication that are needed to find work in a tight job market. Their sagging（消沉的）self-image is not improved when they are rejected by prospective employers who have neither the time nor the budget to train raw recruits. Today business and industry are engaged in myriad mysteriou

23、s machinations（谋划）that challenge the understanding of even the brightest adult. No wonder young people, fresh out of senior government class, are lost! Some high schools acknowledge students needs by offering work experience and career observation and exploration programs. Often the shyest, least su

24、ccessful students will not even apply. For many, approaching the first rung（梯级）of the career ladder is the most difficult step in the entire lifetime career process. Statistics show that the unemployment rate for young adults is two to three times higher than the rate for the remainder of the popula

25、tion. Walter Williams, who teaches at Temple University, favors a lower minimum age and wage for teenagers. He maintains such changes would increase employment for the young, especially minorities, allowing them to step up onto the first rung of the career ladder and gain badly needed work experienc

26、e. Such services as movie ushering and car hopping might be reinstated（恢复）without taking jobs away from older people. 11. According to the author, most high school teenagers _. A. are confident B. are stupid C. lack confidence D. lack financial support 12. The word “peers” in line 2, paragraph 1 mea

27、ns _. A. children B. parentsC. noblemen D. equals13.

30、are sicker. Unfortunately, there are no nationwide mortality（死亡率）statistics by income. One of the best studies has been a recent comparison of poverty and non-poverty areas in Chicago (This does not permit really fine analysis, because of the limitations of area comparisons). Crude mortality in pove

31、rty areas was only three per cent higher than in non-poverty area; but the people in poverty areas are younger, and if it had been possible to compute age-specific rates, the differences would be much greater. Differentials（差异）in infant mortality were very large75 per cent higher in poverty than in

32、non-poverty areas. In both cases, the differences between white and nonwhite were even more substantial than between poverty and non-poverty areas.The clearest and best evidence of poorer health among the poor is to be found in studies of days of disability per person per year, where differences of the order of two-to-one are found. Those in families with income of under $2,000 a year have 29 restricted activity days a ye
