21、tion of our natural resources and contamination of our food supply continue to occur, largely because of the extreme difficulty in affixing legal responsibility on those who continue to treat our environment with reckless abandon. Attempts to prevent pollution by legislation, economic incentives and

22、 friendly persuasion have been met by lawsuits, personal and industrial denial and long delays-not only in accepting responsibility, but more importantly, in doing something about it.It seems that only when government decides it can afford tax incentives or production sacrifices is there any initiat

23、ive for change. Where is industry s and our recognition that protecting mankind s great treasure is the single most important responsibility? If ever there will be time for environmental health professionals to come to the frontlines and provide leadership to solve environmental problems, that time

24、is now.We are being asked, and, in fact, the public is demanding that we take positive action. It is our responsibility as professionals in environmental health to make the difference. Yes, the ecologists, the environmental activists and the conservationists serve to communicate, stimulate thinking

25、and promote behavioral change. However, it is those of us who are paid to make the decisions to develop, improve and enforce environmental standards, I submit, who must lead the charge.We must recognize that environmental health issues do not stop at city limits, county lines, state or even federal

26、boundaries. We can no longer afford to be tunnel-visioned in our approach. We must visualize issues from every perspective to make the objective decisions. We must express our views clearly to prevent media distortion and public confusion.I believe we have a three-part mission for the present. First

27、, we must continue to press for improvements in the quality of life that people can make for themselves. Second, we must investigate and understand the link between environment and health. Third, we must be able to communicate technical information in a form that citizens can understand. If we can a

28、ccomplish these three goals in this decade, maybe we can finally stop environmental degradation, and not merely hold it back. We will then be able to spend pollution dollars truly on prevention rather than on bandages.（分数：5.00）(1).We can infer from the first two paragraphs that the industrialists di

29、sregard environmental protection chiefly because _ .（分数：1.00）A.they are unaware of the consequences of what they are doingB.they are reluctant to sacrifice their own economic interestsC.time has not yet come for them to put due emphasis on itD.it is difficult for them to take effective measures(2).T

30、he main task now facing ecologists, environmental activists and conservationists is _ .（分数：1.00）A.to prevent pollution by legislation, economic incentives and persuasionB.to arouse public awareness of the importance of environmental protectionC.to take radical measures to control environmental pollu

31、tionD.to improve the quality of life by enforcing environmental standards(3).The word “tunnel-visioned“ (Line 2, Para. 4) most probably means “ _ “.（分数：1.00）A.narrow-mindedB.short-sightedC.blind to the factsD.able to see only one aspect(4).Which of the following, according to the author, should play

32、 the leading role in the solution of environmental problems?（分数：1.00）A.Legislation and government intervention.B.The industry s understanding and support.C.The efforts of environmental health professionals.D.The cooperation of ecologists, environmental activists and conservationists.(5).Which of the

33、 following is true according to the last paragraph?（分数：1.00）A.Efforts should be exerted on pollution prevention instead of on remedial measures.B.More money should be spent in order to stop pollution.C.Ordinary citizens have no access to technical information on pollution.D.Environmental degradation

34、 will be stopped by the end of this decade.BPassage 2/BIn the atmosphere, carbon dioxide acts rather like a one-mirror-the glass in the roof of a green-house which allows the sun s rays to enter but prevents the heat from escaping.According to a weather expert s prediction, the atmosphere will be wa

35、rmer in the year 2050 than it is today, if man continues to burn fuels at the present rate. If this warming up took place, the ice caps in the poles would begin to melt, thus raising sea level several meters and severely flooding coastal cities. Also, the increase in atmospheric temperature would le

36、ad to great changes in the climate of the northern hemisphere, possibly resulting in an alteration of the earth s chief food-growing zones.In the past, concern about a man-made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet.

37、But the weather experts are now paying more attention to West Antarctic, which may be affected by only a few degrees of warming: in other words, by a warming on the scale that will possibly take place in the next fifty years from the burning of fuels.Satellite pictures show that large areas of Antar

38、ctic ice are already disappearing. The evidence available suggests that a warming has taken place. This fits the theory that carbon dioxide warm the earth.However, most of the fuel is burnt in the northern hemisphere, where temperatures seem to falling. Scientists conclude, therefore, that up to now

39、 natural influences on the weather have exceeded those caused by man. The question is: Which natural cause has most effect on the weather?One possibility is the variable behavior of the sun. Astronomers at one research station have studied the hot spots and “cold“ spots (that is, the relatively less

40、 hot spots) on the sun. As the sun rotated, every 27.5 days, it presents hotter of “colder“ faces to the earth, and different aspects to different parts of the earth. This seems to have a considerable effect on the distribution of the earth s atmospheric pressure, and consequently on wind circulatio

41、n. The sun is also variable over a long term: its heat output goes up and down in cycles, the latest trend being downward.Scientists are now finding mutual relations between models of solar-weather interactions and the actual climate over many thousands of years, including the last Ice Age. The prob

42、lem is that the models are predicting that the world should be entering a new Ice Age and it is not. One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inertia of the earth s climate. If this is right, the warming effect of

43、carbon dioxide might thus be serving as a useful counter-balance to the suns diminishing heat.（分数：5.00）(1).It can be concluded that a concentration of carbon dioxide in the atmosphere would _ .（分数：1.00）A.prevent the sun s rays from reaching the earth s surfaceB.mean a warming up in the ArcticC.accou

44、nt for great changes in the climate in the northern hemisphereD.raise the temperature of the earth s surface(2).The article was written to explain _ .（分数：1.00）A.the greenhouse effectB.the solar effects on the earthC.the models of solar-weather interactionsD.the causes affecting weather(3).Although t

45、he fuel consumption is greater in the northern hemisphere, temperatures there seem to be falling. This is _ .（分数：1.00）A.mainly because the levels of carbon dioxide are risingB.possibly because the ice caps in the poles are meltingC.exclusively due to the effect of the internal of the earth s climate

46、D.partly due to variations in the output of solar energy(4).On the basis of their models, scientists are of the opinion that _ .（分数：1.00）A.the climate of the world should be becoming coolerB.it will take thousands of years for the inertia of the earth s climate to take effectC.the man-made warming e

47、ffect helps to increase the solar effectsD.the new Ice Age will be delayed by the greenhouse effect(5).If the assumption about the delay of a new Ice Age is correct, _ .（分数：1.00）A.the best way to overcome the cooling effect would be to burn more fuelsB.ice would soon cover the northern hemisphereC.t

48、he increased levels of carbon dioxide in the atmosphere could warm up the earth even more quicklyD.the greenhouse effect could work to the advantage of the earthBPassage 3/BSmog is something combined by smoke and fog. London is always known for its “black fogs“. In the winter of 1952, a milky white fog rolled into the city. It soon turned into black smog as the smoke of the city
