2、d mark the corresponding letter on the Answer Sheet with a single line through the center. Passage OneQuestions 21 to 25 are based on the following passage.There is a difference between science and technology. Science is a method of answering theoretical questions; technology is a method of solving

3、practical problems. Science has to do with discovering the facts and relationships between observable phenomena in nature and with establishing theories that serve to organize these facts and relationships; technology has to do with tools, techniques, and procedures for implementing the finding of s

4、cience.Another distinction between science and technology has to do with the progress in each.Progress in science excludes the human factor. Scientists, who seek to comprehend the universe and know the truth within the highest degree of accuracy and certainty, cannot pay attention to their own or ot

5、her people's likes or dislikes or to popular ideas about the fitness of things. What scientists discover may shock or anger people-as did Darwin's theory of evolution. But even an unpleasant truth is more than likely to be useful; besides, we have the choice of refusing to believe it! But ha

6、rdly so with technology; we do not have the choice of refusing to hear the sonic boom produced by a supersonic aircraft flying overhead; we do not have the option of refusing to breathe polluted air; and we do not have the option of living in a non-atomic age. Unlike science progress, technology mus

7、t be measured in terms of the human factor. The legitimate purpose of technology is to serve people in general, not merely some people; and future generations, not merely those who presently wish to gain advantage for themselves. Technology must be humanistic if it is to lead to a better world.21. T

12、al D) critical Passage TwoQuestions 26 to 30 are based on the following passage.Americans have always been ambivalent in their attitudes toward education. On the one hand, free and universal public education was seen as necessary in a democracy, for how else would citizens learn how to govern themse

13、lves in a responsible way? On the other hand, America was always a country that offered financial opportunities for which education was not needed: on the road from rags to riches, schooling-beyond the basics of reading, writing, and arithmetic-was an unnecessary detour.Even today, it is still possi

14、ble for people to achieve financial success without much education, but the number of situations in which this is possible is decreasing. In today's more complex world, the opportunities for financial success is closely related to the need for education, especially higher education.Our society i

15、s rapidly becoming one whose chief product is information, and dealing with this information requires more and more specialized education. In other words, we grow up learning more and more about fewer and fewer subjects.In the future, this trend is likely to continue. Tomorrow's world will be ev

16、en more complex than today's world, and, to manage this complexity, even more specialized education will be needed.26. The topic treated in this passage is _.A) education in general B) Americans' attitudesC) higher education D) American education27. Americans' attitudes toward education

Passage ThreeQuestions 31 to 35 are based on the following passage.A growing world population and the discoveries of science may alter this pattern of distribution in the future. As men slowly learn to master diseases, control floods, pr

20、event famines, and stop wars, fewer people die every year; and in consequence the population of the world is steadily increasing. In 1925 there were about 2,000 million people in the world; by the end of the century there may well be over 4,000 million.When numbers rise the extra mouths must be fed.

21、 New lands must be brought under cultivation, or land already farmed made to yield larger crops. In some areas the accessible land is so intensively cultivated that it will be difficult to make it provide more food. In some areas the population is so dense that the land is parceled out in units too

22、tiny to allow for much improvement in farming methods. Were a large part of this farming population drawn off into industrial occupations, the land might be farmed much more productively by modern methods. There is now a race for science, technology, and industry to keep the output of food rising fa

23、ster than the number of people to be fed. New strains of crops are being developed which will thrive in unfavorable climates: there are now farms beyond the Arctic Circle in Siberia and North America; irrigation and dry-farming methods bring arid lands under the plough, dams hold back the waters of

24、great rivers to ensure water for the fields in all seasons and to provide electric power for new industries; industrial chemistry provides fertilizers to suit particular soils; aeroplanes spray crops to destroy locusts and many plant diseases. Every year some new means is devised to increase or to p

25、rotect the food of the world.31.

28、hor's main purpose is to _.A) argue for a belief B) describe a phenomenonC) entertain D) propose a conclusion Passage FourQuestions 36 to 40 are based on the following passage.For some time past it has been widely accepted that babies-and other creatures-learn to do things because certain acts l

29、ead to "rewards" and there is no reason to doubt that this is true. But it used also to be widely believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological(生理的) "drives" as thirst or hunger. In other words, a baby would

30、learn if he got food or drink or some sort of physical comfort, not otherwise.It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with no reward except the successful outcome.Papousek began his studies by using milk in the normal way to "re

31、ward" the babies and so teach them to carry out some simple movements, such as turning the head to one side or the other. Then he noticed that a baby who had had enough to drink would refuse the milk but would still go on making the learned response with clear signs of pleasure. So he began to

32、study the children's responses in situations where no milk was provided. He quickly found that children as young as four months would learn to turn their heads to right or left if the movement "switched on" a display of lights-and indeed that they were capable of learning quite complex

33、 turns to bring about this result, for instance, two left or two right, or even to make as many as three turns to one side.Papousek's light display was placed directly in front of the babies and he made the interesting observation that sometimes they would not turn back to watch the lights close

34、ly although they would "smile and bubble" when the display came on. Papousek concluded that it was not primarily the sight of the lights which pleased them, it was the success they were achieving in solving the problem, in mastering the skill, and that there exists a fundamental human urge

35、 to make sense of the world and bring it under intentional control.36. According to the author, babies learn to do things which . A) are directly related to pleasure B) will meet their physical needsC) will bring them a feeling of success D) will satisfy their curiosity37. Papousek noticed in his st

36、udies that a baby .A) would make learned responses when it saw the milkB) would carry out learned movements when it had enough to drinkC) would continue the simple movements without being given milkD) would turn its head to right or left when it had enough to drink38.

38、e lights was interestingC) they need not turn back to watch the lightsD) they succeeded in "switching on" the lights40. According to Papousek, the pleasure babies get in achieving something is a reflection of .A) a basic human desire to understand and control the worldB) the satisfaction o
