The shopper gets rid of the wrapper immediately because ______.

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.

When most people sign on to their computers, they are greeted with a flood of get-rich-quick schemes, invitations to pornographic Web sites, and ads for a variety of unwanted products. The third and best category of e-mail is genuine personal e-mail from genuine personal friends. E-mail users quickly become good at hitting the “delete” button to get rid of this garbage. The second category that clogs most people’s electronic mailbox is forwarded mail, most of which also gets deleted without being read. Getting such real, thoughtful e-mail can almost make up for the irritation of the other two categories. As more and more people take advantage of e-mailing, three categories of e-mail have emerged. One category of e-mail is junk mail.

water depends on where they live. Water gets into a fish's body through osmosis. Take a cell as an example, if there is more water outside of a cell than inside, water will try to flow into the cell until there is the same concentration of water on either side of the cell's membrane. The body of a fish acts the same way, (33) either absorbing or losing water depending on its surroundings.

Whether a fish absorbs or loses water is based on the fact that all fish must maintain a certain amount of salt in their bodies to stay healthy. (34) Fish that live in fresh water have a higher concentration of salt in their bodies than the surrounding water. Consequently, water continuously flows into the fish's body to attempt to dilute the amount of salt in the fish until it is equal to the amount of salt in the surrounding water.

Ocean fish have the opposite problem. Surrounded by salt water, their bodies contain a relatively lower concentration of salt than the ocean water. In this case osmosis causes the fish to constantly lose water in order to equalize salt concentration inside and outside the fish. To partially compensate for the water loss, ocean fish actually drink water through their mouths. And (35) to get rid of the excess salt they take in by drinking seawater, they excrete some salt through cells in their gills.

(30)

A．Water absorbing ability.

B．The cell's membrane.

C．Its surroundings.

D．The ability to maintain salt.
