In his 1979 book, The Sinking Ark, biologist Norman Myers estimated that (1)_____ of more than 100 human-caused extinctions occur each day, and that one million species (2)_____ by the century"s end. Yet there is little evidence of (3)_____ that number of extinctions. For example, only seven species on the (4)_____ species list have become extinct (5)_____ the list was created in 1973. Bio (6)_____ is an important value, according to many scientists. Nevertheless, the supposed mass extinction rates bandied about are (7)_____ by multiplying (8)_____ by improbables to get imponderables. Many estimates, for instance, rely a great deal on a "species-area (9)_____", which predicts that twice as many species will be found on 100 square miles (10)_____ on ten square miles. The problem is that species am not distributed (11)_____, so how much of a forest am destroyed may be as important as (12)_____.

The following paragraphs are given in a wrong order. For Questions 41-45, you are required to reorganize these paragraphs into a coherent article by choosing from the list A-G. Some of the paragraphs have been placed for you. (10 points)A. A machine has been developed that pulps paper and then processes it into packaging, e.g. egg-boxes and cartons. This could be easily adapted for local authorities use. It would mean that people would have to separate their refuse into paper and non-paper, with a different dustbin for each. Paper is, in fact, probably the material that can be most easily recycled; and now, with massive increases in paper prices, the time has come at which collection by local authorities could be profitable.B. Recycling of this kind is already happening with milk bottles, which are returned to the dairies, washed out, and refilled. But both glass and paper are being threatened by the growing use of plastic. More and more dairies are experimenting with plastic bottles, and it has been estimated that if all the milk bottles necessary were made of plastic, then British dairies would be producing the equivalent of enough plastic tubing to encircle the earth every five or six days!C. The package itself is of no interest to the shopper, who usually throws it away immediately. Useless wrapping accounts for much of the refuse put out by the average London household each week. So why is it done Some of it, like the cellophane on meat, is necessary, but most of the rest is simply competitive selling. This is absurd. Packaging is using up scarce energy and resources and messing up the environment.D. The trouble with plastic is that it does not rot. Some environmentalists argue that the only solution to the problem of ever growing mounds of plastic containers is to do away with plastic altogether in the shops, a suggestion unacceptable to many manufacturers who say there is no alternative to their handy plastic packs.E. Little research, however, is being carried out on the costs of alternative types of packaging. Just how possible is it, for instance, for local authorities to salvage paper, pulp it and recycle it as egg-boxes Would it be cheaper to plant another forest Paper is the material most used for packaging—20 million paper bags are apparently used in Great Britain each day—but very little is salvaged.F. It is evident that more research is needed into the recovery and re-use of various materials and into the cost of collecting and recycling containers as opposed to producing new ones. Unnecessary packaging, intended to be used just once, and making things look better so that more people will buy them, is clearly becoming increasingly absurd. But it is not so much a question of doing away with packaging as using it sensibly. What is needed now is a more sophisticated approach to using scarce resources for what is, after all, a relatively unimportant function.G. To get a chocolate out of a box requires a considerable amount of unpacking: the box has to be taken out of the paper bag in which it arrived; the cellophane wrapper has to be torn off, the lid opened and the paper removed; the chocolate itself then has to be unwrapped from its own piece of paper. But this insane amount of wrapping is not confined to luxuries. It is now becoming increasingly difficult to buy anything that is not done up in cellophane, polythene or paper.Notes:cellophane (包装用的)玻璃纸 do up 打包,装饰 polythene 聚乙烯refuse n.废料,废物 mess up 弄脏,弄乱 salvage 回收利用pulp 使…成为浆状 carton 纸板盒 encircle 环绕mound 小丘,小堆 do away with 处理掉 as opposed to 与…对照not so much...as 与其…倒不如…"Order: G is the first paragraph and F is the last one.

In most people"s mind, growth is associated with prosperity. We judge how well the economy is doing by the size of the Gross National Product (GNP), a measure, supposedly, of growth. Equally axiomatic, however, is the notion that increased pressure on declining natural resources must inevitably lead to a decline in prosperity, especially when accompanied by a growth in population. So, which is correct What growth advocates mean, primarily, when they say growth is necessary for prosperity is that growth is necessary for the smooth functioning of the economic system. In one field the argument in favor of growth is particularly compelling and that is with regard to the Third World. To argue against growth in light of Third World poverty and degradation seems unsympathetic. But is it Could it be that growth, especially the growth of the wealthier countries, has contributed to the impoverishment, not the advancement, of Third World countries If not, how do we account for the desperate straits these countries find themselves in today after a century of dedication to growth To see how this might be the case we must look at the impact of growth on Third World countries—the reality, not the abstract stages-of-economic-growth theory advocated through rose-colored glasses by academicians of the developed world. What good is growth to the people of the Third World if it means the conversion of peasant farms into mechanized agri-businesses producing commodities not for local consumption but for export, if it means the stripping of their land of its mineral and other natural treasures to the benefit of foreign investors and a handful of their local collaborators, if it means the assumption of a crushing foreign indebtedness Admittedly, this is an oversimplification. But the point, I believe, remains valid: that growth in underdeveloped countries cannot simply be judged in the abstract; it must be judged based on the true nature of growth in these societies, on who benefits and who is harmed, on where growth is leading these people and where it has left them. When considered in this way, it just might be that in the pre sent context growth is more detrimental to the well-being of the wretched of the earth than beneficial. So, do we need growth for prosperity Only the adoption of zero growth can provide the answer. But that is a test not easily undertaken. Modern economies are incredibly complex phenomena, a tribute to man"s ability to organize and a challenge to his ability to understand. Anything that affects their functioning, such as a policy of zero growth, should not be proposed without a wary carefulness and self-doubting humility. But if the prospect of leaping into the economic unknown is fear-inspiring, equally so is the prospect of letting that fear prevent us from acting when the failure to act could mean untold misery for future generations and perhaps environmental disaster which threaten our very existence. We can learn from the last paragraph, zero growth

A. will be attained through dramatic social changes
B. is the best policy in the long rum
C. is worth trying though perhaps not safe.
D. needs further consideration to determine its feasibility.
