Question

It is often said that man has become the enemy of our planet. This is no exaggeration(夸张), for reports show that man’s greed has done much to destroy the earth. Man, in his greedy desire for financial growth, has polluted the air, land and water, and has robbed our valuable natural resources. Man’s industrial plants pour out poisonous waste that pollutes the sea and puts life in the sea under the threat of dying out; at the same time, they release alarming amounts of carbon dioxide, chlorofluorocarbons (CFCs) and other pollutants. Small wonder that the air now is much warmer and more impure than ever before.
Of course, this is not just because of man’s greed—it is man’s pressing need as well. For instance, in developing countries, huge financial foreign debts have forced governments to approve the cutting of forests for agriculture or ranching. As a result, forests are cut down just to meet man’s immediate needs.
Perhaps unknowingly，man has changed the make-up of the earth's atmosphere. Scientific studies have shown that CFCs used in refrigerators and industrial cleaners are fast destroying the ozone layer—a protective layer in the atmosphere that protects us against the harmful effects of the sun’s ultraviolet (紫外线)rays. In fact, documented reports have shown a terrible fact that there are “holes” in the ozone layer over the Antarctic. And they appear to be expanding.
Faced with these environmental problems, world leaders have shown deep concern. The UN Environmental Programme (UNEP) has arranged international agreements like the Vienna convention of 1985 and the Montreal Protocol of 1989 to preserve the ozone layer by controlling the production, use and trade of destructive chemicals.
There may be some doubt as to how effectual these agreements may be, given that some countries still maintain an “I-don’t-care” attitude. Their attitude is probably due to their failure to grasp the importance of the problem. Then, there is no doubt that environmental education on an international scale（规模）is greatly needed, so that all countries, great and small—the “haves” and the “have nots”—may realize their responsibilities for our planet.
In the meantime, the UNEP seems to have taken steps in the right direction, and it is hoped that in the not so distant future, all nations of the world will join hands in saving mother earth.

解析试题分析：文章大意：人类的贪婪已使得人类成为地球最大的敌人。
【小题1】B 细节理解题。根据文章第二段in developing countries, huge financial foreign debts have forced governments to approve the cutting of forests for agriculture or ranching.可知人们伐木造田。故C正确。
【小题2】D细节理解题。根据文章第三段Scientific studies have shown that CFCs used in refrigerators and industrial cleaners are fast destroying the ozone layer可知臭氧层洞扩大是由于冰箱的氟利昂和工业污染。故C正确。
【小题3】C推理题。根据文章倒数第二节Their attitude is probably due to their failure to grasp the importance of the problem.可以推断出一些国家不关心环境问题是因为他们还没有认识到问题的重要性。 故B正确。
【小题4】A 推理题。根据文章最后一段and it is hoped that in the not so distant future, all nations of the world will join hands in saving mother earth.可以推断出作者对未来环境的态度是怀有希望的。故A正确。
