单选题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 overuse of wrapping is not confined to luxuries. It is now becoming increasingly difficult to buy anything that is not done up in beautiful wrapping. 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. Recycling 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 dairies are experimenting with plastic bottles. The trouble with plastic is that it does not rot. Some environmentalists argue that the only solution to the problem of ever increasing 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. It is evident that more research is needed into the recovery and reuse 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 make things look better so 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 advanced approach to using scarce resources for what is, after all, a relatively unimportant function.

单选题Smokers who want to kick the habit might soon get help from a product that's being tested at the University at Buffalo School of Dental Medicine: a mouth wash that makes cigarettes taste bad. It could be on the market within a year. The anti-smoking rinse itself tastes rather pleasant. But if you light up within 6 to 8 hours of smoking it, your cigarette will taste like burnt rubber and you won't smoke past the first puff, explains Dr. Sebastian Ciancio, director of the Center for Dental Studies at the University of Buffalo. Ciancio is heading up a pilot study in which 10 smokers, each of whom normally smoke at least a pack of cigarettes a day, are rinsing their mouths three times daily with the anti-smoking solution. Another 10 are getting a placebo. Prior to this study, only the inventor had tested the anti-smoking rinse—a chemist who does not wish to be identified—and a few of his friends, who say it enabled them to quit smoking. And Ciancio has no shortage of volunteers: The waiting list to participate in the study is already full. "People arc desperate," he says. If the pilot study is successful, it will be expanded. Not only might the patented formulation deter smoking, Ciancio adds, but it also appears to reduce plaque, gingivitis, and halitosis. Manufacturing the rinse, he estimates, would cost approximately the same as conventional mouthwashes.

单选题{{B}}Text 3{{/B}} Blocks of "high-rise" flats have been built in large numbers in London and in many other big cities. Just after the Second World War these big, twenty-to-thirty storey buildings, hundreds of feet in height, were thought to be the ideal solution to the housing problem. For on the one hand, there was severe housing shortage, but on the other hand, there was lack of space to build houses in urban areas. Blocks of "high-rise" flats seemed at first to be able to solve the problem, since they can offer more families to live in on less land. The beautiful, modem apartments in the high-rises were much sought after by people who lived downtown. Hundreds of the vast blocks had been built before anyone began to doubt about whether they were good solutions or not. Are they suitable places for people, children especially, to live in? A well-known British architect, who personally designed many of these buildings, now believes that the high-rises may well make those people who have been housed in them suffer a great deal. Evidence has been collected by social workers, which suggests that people do suffer. They complain about severe loneliness and deep depression living within these great towers. People also talk about lack of communication with others, no easy access to a playground for children, no chances for adults to get familiarized with each other. Many people say that they have lived next door to each other for years in the same building, but they never know who their neighbors are. Some experts say that a large number of people living in the high-rises suffer from mental disorder and even developed criminal tendencies. As a result of these new discoveries, plans for new high-rise blocks are being reconsidered. We Chinese are now building up many high-rises in big cities such as Beijing, Shanghai and Guangzhou. Perhaps we should also reconsider the idea too.
