In your essay, you should first describe the drawing, then interpret its meaning, and give your comment

13、on it. You should write neatly on ANSWER SHEET 2. (20 points)* （分数：1.00）_三、Section Reading(总题数：4，分数：4.00)Rumor has it that more than 20 books on creationism/evolution are in the publishers pipelines. A few have already appeared. The goal of all will be to try to explain to a confused and often unenl

14、ightened citizenry that there are not two equally valid scientific theories for the origin and evolution of universe and life. Cosmology, geology and biology have provided a consistent, unified, and constantly improving account of what happened. “Scientific“ creationism, which is being pushed by som

15、e for “equal time“ in the classrooms whenever the scientific accounts of evolution are given, is based on religion, not science. Virtually all scientists and the majority of nonfundamentalist religious leaders have come to regard “scientific“ creationism as bad science and bad religion. The first fo

16、ur chapters of Kitcher s book give a very brief introduction to evolution. At appropriate places, he introduces the criticisms of the creationists and provides answers. In the last three chapters, he takes off his gloves and gives the creationists a good beating. He describes their programmes and ta

17、ctics, and, for those unfamiliar with the ways of creationists, the extent of their deception and distortion may come as an unpleasant surprise. When their basic motivation is religious, one might have expected more Christian behavior. Kitcher is a philosopher, and this may account, in part, for the

18、 charity and effectiveness of his arguments. The nonspecialist will be able to obtain at least a notion of the sorts of data and argument that support evolutionary theory. The final chapters on the creationists will be extremely clear to all. On the dust jacket of this fine book, Stephen Jay Gould s

19、ays:“ This book stands for reason itself.“ And so it doesand all would be well were reason the only judge in the creationism/evolution debate. （分数：1.00）(1).“Creationism“ in the passage refers to_.（分数：0.25）A.evolution in its true sense as to the origin of the universeB.a notion of the creation of rel

20、igionC.the scientific explanation of the earth formationD.the deceptive theory about the origin of the universe(2).Kitcherss book is intended to_.（分数：0.25）A.recommend the views of the evolutionistsB.expose the true features of creationistsC.curse bitterly at his opponentsD.launch a surprise attack o

21、n creationists(3). From the passage we can infer that_.（分数：0.25）A.reasoning has played a decisive role in the debateB.creationists do not base their argument on reasoningC.evolutionary theory is too difficult for non-specialistsD.creationism is supported by scientific findings(4).This passage appear

22、s to be a digest of_.（分数：0.25）A.a book reviewB.a scientific paperC.a magazine featureD.a newspaper editorialIn spite of rising concern in the Northeast and Canada, Administration spokesmen have repeatedly insisted that nothing could really be done about acid rain and the industry-produced sulfur emi

23、ssions until all the scientific facts were in. Suddenly last week, however, facts came raining down, in effect making further scientific debate on what mainly causes the problem all but irrelevant. What brought about the downpour was a study commissioned by Presidential Science Adviser. The spokesme

24、n plainly called for remedial action even if some technical questions about acid rain were still unanswered. “If we take the conservative point of view that we must wait until the scientific knowledge is definitive,“ said the spokesman, “the accumulated deposition and damaged environment may reach t

25、he point of irreversibility.“ When it rains, it pours. Next came a study from the National Research Council. Its definitive conclusion: reducing emissions of sulfur dioxide from coal-burning power plants and factories, such as these in the Midwest, would in fact significantly reduce the acidity in r

26、ain, snow and other precipitation(降水) that is widely believed to be worsening the life from fresh-water lakes and forests in the Northeast and Canada. The spokesman did not recommend any specific action. A pair of remedial measures are already taken before Congress. A Senate committee recently appro

27、ved a bill that would require reduction over the next decade of sulfur-dioxide emissions by 10 million tons in the States bordering on the east of the Mississippi. A tougher measure was introduced in the House ordering the 50 largest sulfur polluters in the U. S. to cut emissions substantially. To e

28、ase the Eastern coal mining industry, which fears a switch to low-sulfur Western coal, the bill requires the installation of expensive “scrubbers“, devices for removing sulfur from the smoke, rather than an order that forbids high-sulfur fuel. Still, the legislation is being vigorously opposed by th

29、e coal industry and utilities, especially in the Mid-west, where heavy industries are battling to survive. In a survey also released last week, the Edison Electric Institute , an industry group, gravely predicted that electricity rates could rise as much as 50% if the emission-control legislation pa

30、ssed. Government studies dispute these figures, but Congress has been suspended on acid-rain measures. Now, as a result of the academy study, supporters of the bills are more optimistic. Nevertheless, a major political battle is shaping up. （分数：1.00）(1).The first paragraph shows that（分数：0.20）A.the A

31、dministration has ignored the public anxiety about acid rain.B.the industrial sulfur emissions need further scientific verificationC.the spokesmen have denied the presence of proofs of acid rain.D.scientific evidence has made the cause of acid rain undebatable.(2). The word “downpour“ in the second

32、paragraph most likely refers to（分数：0.20）A.a heavy fall of acid rain.B.a sudden thunderstorm.C.a series of criticism.D.a succession of evidence.(3).This article most probably appeared in（分数：0.20）A.a government document.B.a news magazine.C.a scientific research paper.D.a textbook of environmental scie

33、nce.(4). The two studies mentioned in the text clearly stated that（分数：0.20）A.there is no time to lose in pollution control.B.the scientific explanation of acid rain remains unclear.C.environmental restoration defies scientific endeavors.D.factories should be banned from burning coal.(5).From the des

34、cription of the efforts in the House, we can see that（分数：0.20）A.the members of the House really speak for the general public.B.the Congressmen are tough to the sulfur polluters in the U. S.C.the statesmen try to please the public without enraging the bosses.D.the politicians worry about the effect o

35、f emission-control legislation.While disease is present prior to social organization, communal life creates special hazards. While the organization of society can reduce the dangers of disease, trade and urbanization, with their consequent problems of sanitation and pollution, can also aggravate suc

36、h dangers. Even in the mid-twentieth century, during the brief calm between the polio and AIDS epidemics, epidemic health risks associated with carcinogens (cancer-producing substances ) from polluted air threatened the industrialized world. To the economist, efforts to combat these risks are at lea

37、st partially public goods. The benefits from public goods are indivisible among beneficiaries. A sole private purchaser of health care would give others in society a “free ride“ with respect to the benefits obtained. To market theorists, such goods are lawful objects of governmental intervention in

38、the market. While the theory of public goods helps explain aspects of public health law and assists in fitting it into modern economic theory, it omits a critical point. Ill health is not a mere byproduct of economic activity, but an inevitable occurrence of human existence. As a result, wherever th

39、ere is human society, there will be public health. Every society has to face the risks of disease. And because it must, every society searches to make disease comprehensible within the context of the societys own particular culture, religion, or science. In this sense, health care is public not only

40、 because its benefits are indivisible and threats to it arise from factors outside of the individual but also because communal life gives individuals the cultural context in which to understand it. Governments typically have assumed an active role with respect to health care, acting as if their role

41、 were obligatory. How governments have fulfilled that duty has varied throughout time and across societies, according not only to the wealth and scientific sophistication of the culture but also to its fundamental values-because health is defined in part by a communitys belief system, public health

42、measures will necessarily reflect cultural norms and values. Those who criticize the United States government today for not providing health care to all citizens equate the provision of health care with insurance coverage for the costs of medical expenses. By this standard, seventeenth and eighteent

43、h-century America lacked any significant conception of public health law. However, despite the general paucity (scarcity) of bureaucratic organization in pre-industrial America, the vast extent of health regulation and provision stands out as remarkable. Of course, the public role in the protection

44、and regulation of eighteenth-century health was carried out in ways quite different from those today. Organizations responsible for health regulation were less stable than modern bureaucracies ,tending to appear in crises and fade away in periods of calm. The focus was on epidemics which were seen a

45、s unnatural and warranting a response ,not to the many prevalent and chronic conditions which were accepted as part and parcel of daily life. Additionally ,and not surprisingly ,religious influence was significant ,especially in the seventeenth century. Finally, in an era which lacked sharp division

46、s between private and governmental bodies, many public responsibilities were carried out by what we would now consider private associations. Nevertheless, the extent of public health regulation long before the dawn of the welfare state is remarkable and suggests that the founding generations assumpt

47、ions about the relationship between government and health were more complex than commonly assumed. （分数：1.00）(1).The authors primary purpose is to（分数：0.20）A.comment on the government role in health-care provision.B.argue about the social organizations tasks concerning health care.C.trace the historical development of the national health-care system.D.discuss the societal duty to make provision agai
