问题     The following paragraphs are given in a wrong order. You are required to reorganize these paragraphs into a coherent article by choosing from the list A—G. The first and the last paragraphs have been placed for you.

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.

Order: G is the first paragraph and F is the last.
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 型脏，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…。

选项
答案E
解析 C最后一句写道："包装正在用尽短缺的能源和资源，弄脏了环境"。E表示转折："然而，对于各种可以替代的包装的成本研究几乎没有进行"。接着，通过for instance具体说明哪些问题没有研究。可见，E中的第1句起到了承上启下的作用。解题技巧：瞻前顾后。
