Each passage is followed by some questions or unfinished statements. For each of them there are four choi _s _red A）, B）, C） and D）.You should

2、decide on the best choi _ and _rk the corresponding letter on the Answer Sheet with a single line through the _nter. Passage One Questions 21 to 25 are based on the following passage: There are three basic ways in which individual economic units interact with one another. They are the _rket system,

3、the administered system, and the traditional system. In a _rket system, individual economic units are free to interact among each other in the _rket pla _. Transactions _y take pla _ through barter or money exchange. In a barter economy,real goods such as automobiles, shoes, and pizzas are traded ag

4、ainst each other. Obviously, finding somebody who wants to trade an old car in exchange for a sailboat _y not always be an easy task. Hen _ the introduction of money as a medium of exchange eases transactions considerably. An alternative to the _rket system is administered control by some agency ove

5、r all transactions. This agency will issue laws or _nds as to how much each goods and servi _ should be produ _d, exchanged, and consumed by each economic unit. Central planning _y be one way of administering such an economy. The _ntral plan drawn up by the gover _ent shows the amount of each modity

6、 produ _d by the various firms and distributed to different households for consumption. In a traditional society, production and consumption patterns are governed by tradition. Each persons pla _ with the economic system is fixed by parentage, religion, and custom. Transactions take pla _ on the bas

7、is of tradition, too. People belonging to a _rtain group or caste _y have an obligation to care for other persons, provide them with food and shelter, care for their health,and provide for their education. Clearly, in a system where every decision is _de on the basis of tradition alone progress _y b

Passage Two Questions 26 to 30 are based on the following passage: In the atmosphere, carbon dioxide （二氧化碳） acts rather like a one-way

12、 mirrorthe glass in the roof of a greenhouse which allows the suns rays to enter but prevents the heat from escaping.Aording to a weather experts prediction, the atmosphere will be 3 warmer in the year 2050 than it is today, if _n continues to burn fuels at the present rate. If this warming up took

13、pla _, the i _ caps in the poles would begin to melt, thus raising sea level several metres and severely flooding coastal cities, Also, the increase in atmospheric temperature would lead to great changes in the cli _te of the northern hemisphere, possibly resulting in an alteration of the earths-chi

14、ef food-growing zones. In the past, con _rn about a _n- _de warming of the earth has con _ntrated on the Arctic because the Antarctic is much colder and has a much thicker i _ sheet. But the weather experts are now paying more attention to West Antarctic, which _y be affected by only a few degrees o

15、f warming: in other words, by a warming on the scale that will possibly take pla _ in the next fifty years from the burning of fuels. Sa _ite pictures show that large areas of Antarctic i _ are already disappearing. The eviden _ available suggests that a warming has taken pla _. This fits the theory

16、 that carbon dioxide warms the earth. However, most of the fuel is burnt in the northern hemisphere,where temperatures seem to be falling. Scientists conclude,therefore, that up to now natural influen _s on the weather have ex _eded those caused by _n. The question is: Which natural cause has most e

17、ffect on the weather? One possibility is the variable behavior of the sun. Astronomers at one research station have stu _d the hot spots and cold spots（that is, the relatively less hot spots） on the sun.As the sun rotates, every 27.5 days, it presents hotter or colder fa _s to the earth, and differe

18、nt aspects to different parts of the earth. This seems to have a considerable effect on the distribution of the earths atmospheric pressure, and consequently on wind circulation. The sun is also variable over a long term: its heat output goes up and down in cycles, the latest trend being downward. S

19、cientists are now finding mutual relations between models or solar-weather interactions and the actual cli _te over _ny thousand of years, including the last I _ Age. The problem is that the models are predicting that the world should be entering a new I _ Age and it is not. One way of solving this

20、theoretical difficulty is to assume a delay of thousands of years while the solar effects overe the inertia of the earths cli _te. If this is right, the warming effect of carbon dioxide might thus be serving as a useful counter-balan _ to the suns diminishing heat. 26. It can be concluded that a con

21、 _ntration of carbon dioxide in the atmosphere would . A） prevent the suns rays from reaching the earths su _ _ B） mean a warming up in the Arctic C） aount for great changes in the cli _te in the northern hemisphere D） raise the temperature of the earths su _ _ 27. The article was written to explain

22、 . A） the greenhouse effect B） the solar effects on the earth C） the models of solarweather interactions D） the causes affecting weather 28. Although the fuel consumption is greater in the northern hemisphere, temperatures there seem to be falling. This is . A） _inly because the levels of carbon dio

23、xide are rising B） possibly because the i _ caps in the poles are melting C） exclusively due to the effect of the inertia of the earths cli _te D） partly due to variations in the output of solar energy 29. On the basis of their models, scientists are of the opinion that . A） the cli _te of the world

24、 should be being cooler B） it will take thousands of years fro the inertia of the earths cli _te to take effect C） the _n _de warming effect helps to increase the solar effect D） the new I _ Age will be delayed by the greenhouse effect 30. If the assumption about the delay of a new I _ Age is correc

25、t, . A）the best way to overe the cooling effect would be to burn more fuels B） i _ would soon cover the northern hemisphere C） the increased levels of carbon dioxide in the atmosphere could warm up the earth even more quickly D）the greenhouse effect could work to the advantage of the earth Passage T

26、hree Questions 31 to 35 are based on the following passage: Before the 1850s the United States had a number of s _ll colleges, most of them dating from colonial days. They were s _ll,church-connected institutions whose pri _ry con _rn was to shape the moral character of their students. Throughout Eu

27、rope, institutions of higher learning had developed, bearing the ancient name of university. In Ger _ny a different kind of university had developed. The Ger _n university was con _rned pri _rily with creating and spreading knowledge,not morals. Between mid _ntury and the end of the 1800s, more than

28、 nine thousand young Americans, dissatisfied with their training at home, went Ger _ny for advan _d study. Some of them returned to bee presidents of venerable （受人尊敬的 ） collegesHarvard, Yale, Columbiaand transform them into modern universities The new presidents broke all ties with the churches and

29、brought in a new kind of faculty. Professors were hired for their knowledge of a subject, not because they were of the proper faith and had a strong arm for disciplining students. The new principle was that a university was to create knowledge as well as pass it on,and this called for a faculty pose

30、d of teacherscholars. Drilling and learning by rote （死记硬背 ） were repla _d by the Ger _n method of lecturing, in which the professors own research was presented in class. Graduate training leading to the Ph. D, an ancient Ger _n degree signifying the highest level of advan _d scholarly attai _ent, wa

31、s introdu _d. With the establishment of the seminar system, graduate students learned to question, _yze,and conduct their own research. At the same time, the new university greatly expanded in size and course offerings, breaking pletely out of the old, constricted curriculum of _the _tics, classics,

32、 rhetoric, and music. The president of Harvard pioneered the elective system, by which students were able to choose their own courses of study. The notion of _jor fields of study emerged. The new goal was to _ke the university relevant to the real pursuits of the world. Paying close heed to the prac

33、tical needs of society, the new universities trained men and women to work at its tasks, with engineering students being the most characteristic of the new regime. Students were also trained as economists, architects, agriculturalists, social welfare workers, and teachers. 31. The word this （senten

34、_ 8, Para. 2） refers to which of the following? A） Creating and passing on knowledge. B） Drilling and learning by rote. C） Disciplining students. D） Developing moral principles. 32. Aording to the passage, the seminar system encouraged students to . A） discuss moral issues B） study the classics, rhe

35、toric, and music C） study overseas D） work more independently 33. It can be inferred from the passage that before 1850, all of the following were Characteristic of higher education EXCEPT . A） the elective system B） drilling C） strict discipline D） rote learning 34. Those who favored the new univers

36、ity would be likely to agree with which of the following statements? A） Learning is best achieved through discipline and drill. B） Shaping the moral character of students should be the pri _ry goal. C） Higher education should prepare students to contribute to society. D） Teachers should select their

37、 students courses. 35. Why _ny students decided to study aboard? A）Because thousands of young Americans wanted to go to Ger _ny to study. B）Because young Americans were not satisfied with their school system in the USA. C）Because American professors were not as good as those abroad. D）Because Europe

38、an universities were not connected with churches. Passage Four Questions 36 to 40 are based on the following passage: The nuclear age in which the hu _n ra _ is living, and _y soon be dying, began for the general public with the dropping of an atom bomb on Hiroshi _ on 6 August 1945. But for nuclear

39、 scientists and for _rtain American authorities, it had been known for some time that such a weapon was possible. An atom consists of a tiny core called the nucleus with attendant electrons circling round it. The hydrogen atom, which is the _st and lightest, has only one electron. Heavier atoms have

40、 more and more as they go up the scale. The first discovery that had to do with what goes on in nuclei was radioactivity, which is caused by particles being shot out of the nucleus. It was known that a great deal of energy is locked up in the nucleus, but until just before the outbreak of the Second

41、 World War, there was no way of releasing this energy in any large quantity. A revolutionary discovery was that, in _rtain circumstan _s, _ss can be transformed into energy in aordan _ with Einsteins formula which states that the energy generated is equal to the _ss lost multiplied by the square of

42、the velocity of light. The A-bomb, however, used a different pro _ss, depending upon radioactivity. In this pro _ss, called fission, a heavier atomsplits into two lighter atoms. In general, in radioactive substan _s this fission pro _eds at a constant rate which is slow where substan _s ourring in n

43、ature are con _rned. But there is one form of uranium called U235 which, when it is pure, sets up a chain reaction which spreads like fire, though with enormously greater rapidity. It is this substan _ that was used in _ the atom bomb. The political background of the atomic scientists work was the d

44、etermination to defeat the Nazis. It was heldI think rightlythat a Nazi victory would be an appalling disaster. It was also held, in Western countries, that Ger _n scientists must be well advan _d towards _ an A-bomb, and that if they sueeded before the West did they would probably win the war. When

45、 the war was over,it was discovered, to the plete astonishment of both American and British scientists, that the Ger _ns were nowhere near suess, and, as everybody knows, the Ger _ns were defeated before any nuclear weapon had been _de. But I do not think that nuclear scientists of the West can be b

46、lamed for thinking the work urgent and ne _ssary. Even Einstein favored it. When, however, the Ger _n war was finished, the great _jority of those scientists who had collaborated towards _ the A-bomb considered that it should not be used against the Japanese,who were already on the verge （边缘） of def

47、eat and, in any case,did not constitute such a mena _ to the world as Hitler. Many of them _de urgent represent ations to the American Gover _ent advocating that, instead of using the bomb as a weapon of war, they should after a public announ _ment, explode it in a desert, and that future control of

48、 nuclear energy should be pla _d in the hands of an international authority. Seven of the most eminent of nuclear scientists drew up what is known as The Franck Report which they presented to the Secretary of War in June 1945. This is a very admirable and far-seeing document, and if it had won the a

49、ssent of the politicians, none of our subsequent terrors would have arisen. 36. We _y infer that the writers attitude towards the A bomb is that . A） it is a ne _ssary evil B） it is a terrible threat to the whole of _nkind C） it played a vital part in defeating the Japanese D） it was a wonderful inv

50、ention 37. Aording to the passage, an atom is heavy if . A） it has a large nucleus B） it is radioactive C） its nucleus has _ny electrons D） its nucleus shoots out _ny particles 38. The American and British scientists were astonished at the end of the Second World War against Ger _ny because . A）the

51、Ger _ns had been defeated without the use of nuclear weapons B）the Western countries had won before they had invented nuclear weapons C） they thought the Ger _ns would probably win the war D）the Ger _ns had _de little progress in developing nuclear weapons 39. Aording to the writer, most scientists

52、who had helped in _ the A bomb considered that it should not be used against the Japanese because . A） it was such a dangerous weapon B） its use against the Japanese, was unne _ssary C） it was a very inhu _ne weapon D） the Ger _n war was finished 40.It is implied that the nuclear scientists . A）migh

53、t not have agreed to develop the bomb if there had been no Nazi threat B） would have developed the bomb even without the Nazi threat C）would have _de the bomb, under pea _time conditions, but only for the use of an international authority D）developed the bomb because Einstein thought it urgent and n
