Many American families pride themselves () their cooking, and have deep freezers, () they store foodthey grow in their gardens or buy in the supermarket. Supermarkets are large self service stores () every kind of food--fresh, canned or frozen. So, () the fast-food restaurant, their produce is less expensive andeasier () .

be taken out of its paper bag; the plastic wrapper has to be torn off, the lid opened and the packing paper inside removed; the chocolate itself then has to be unwrapped from its own piece of paper. Similarly a pot of face cream comes surrounded by layers of paper, waged inside a cardboard box, and the whole thing wrapped tightly in plastic.

It is not only luxuries which are wrapped in this way, With so many goods now produced centrally and sold in supermarkets it is becoming increasingly difficult to buy anything from nails to potatoes that is not already done up in plastic or paper.

The wrapper itself is of no interest to the shopper, who usually throws it away immediately. Useless wrapping accounts for much o the 31 pounds in weight of rubbish put out by the average London household each week. So why is it done？ Some of it, like the wrapping on meat, is necessary, but most of the rest is simply competitive selling. This is stupid. Packaging is using up scarce energy and raw materials and ruining all the time. One big firm reports that its glass, cans and paper have all gone up by 30 per cent in the last couple of months, while plastic has increased by 50 percent and all these prices are still rising. This seems as yet to have had surprisingly little effect on the packaging practice of manufacturers.

Little research is being carried out on the costs in energy and materials of other possible types of packaging. Just how practical is it, for instance, for local authorities to save waste paper and re-manufacture it as egg-boxes？ Would it be cheaper to plant another forest to produce new paper？

One reason for the unorganized behavior. of everyone concerned is probably the varied nature of the packaging industry. So many people, with so many different interests of their own, are affected that it is extremely hard to reach any agreement on what should be done. Also, packagers say that preserving forests and preventing waste is not their concerns.

The shopper gets rid of the wrapper immediately because______.

A．he is careless.

B．it adds to the weight.

C．it is difficult for him to handle.

D．it has no importance for him.

Prehistoric men and women enjoyed a more varied diet(饮食)than people do now, since they ate species(种类)of plant and several hundred thousand types of living things. But only a tiny percentage of these were ever domesticated(驯化). Modern shops have hastened a trend towards specialization which began in the earliest days of agriculture. The food of rich countries has become cheaper relative to wages. It is speedily distributed in supermarkets, but the choice annually becomes less and less great. Even individual foods themselves become more standardized. We live in the world of the carrot specially blunted in order to avoid making a hole in the bag, and the tomato grown to meet a demand for a standard weight of eighteen tomatoes to a kilo. Siri von Reis Altschul asks: "Only the tree major cereals(谷物)and perhaps ten other widely cultivated species stand between famine and survival for the world's human population and a handful of drug plants has served Western civilization for several thousand years. A rather obvious question arises: are we missing something？" After all, there are 800,000 species of plant on earth.
