单选题{{B}}Text 2{{/B}} 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{{B}}Text 2{{/B}} Botany, the study of plants, occupies a peculiar position in the history of human knowledge. For many thousands of years it was the one field of awareness about which humans had anything more than the vaguest of insight. It is impossible to know today just what our Stone Age ancestors knew about plants, but from what we can observe of preindustrial societies that still exist, a detailed learning of plants and their properties must be extremely ancient. This is logical. Plants are the basis of the food pyramid for all living things, even for other plants. The have always been enormously important to the welfare of people, not only for food, but also for clothing, weapons, tools, dyes, medicines, shelter, and a great many other purposes. Tribes living today in the jungles of the Amazon recognized literally hundreds of plants and know many properties of each. To them botany, as such, has no name and is probably not even recongnized as a special branch of knowledge at all. Unfortunately, the more industrialized we become the farther away we move from direct contact with plants, and the less distinct our knowledge of botany grows. Yet everyone comes unconsciously on an amazing amount of botanical knowledge, and few people will fail to recognize a rose, an apple, or an orchid. When our Neolithic ancestors, living in the Middle East about 10,000 years ago, discovered that certain grasses could be harvested and their seeds planted for richer yields the next season, the first great step in a new association of plants and humans was taken. Grains were discovered and from the flowed the marvel of agriculture-. cultivated crops. From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varieties that grew wild—and the accumulated knowledge of tens of thousands of years of experience and intimacy with plants in the wild would begin fade away.

单选题A few weeks ago, we decided to paint (油漆) the outside of our house. To save money, we decided to do it ourselves. On Saturday morning, we went to the shops and bought some paint and a number of brushes. We already had a ladder (梯子), so we were then ready to start. We began that afternoon with the back of the house. The next Saturday I went to a football match while my wife painted the front of the house. On Sunday we found that we could not open any of the front windows. We got them all open in the end but I broke three and they were very expensive to repair. Next time when we try to save money, I shall certainly pay someone to do the work.

单选题Questions 11-14 are based on the following dialogue:

单选题With only about 1,000 pandas left in the world, China is desperately trying to clone the animal and save the endangered species. That's a move similar to what a Texas A&M University researcher has been undertaking for the past five years in a project called "Noah's Ark." Dr. Duane Kraemer, a professor in Texas A&M's College of Veterinary Medicine and a pioneer in embryo(胚胎) transfer work and related procedures, says he salutes the Chinese effort and "I wish them all the best success possible. It's a worthwhile project, certainly not an easy one, and it's very much like what we're attempting here at Texas A&M--to save animals from extinction." Noah's Ark is aimed at collecting eggs, embryos, semen (精子) and DNA of endangered animals and storing them in liquid nitrogen. If certain species should be come extinct, Kraemer says there would be enough of the basic building blocks to reintroduce the species in the future. It is estimated that as many as 2,000 species of mammals, birds and reptiles w ill become extinct over the next 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years. This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal. The entire procedure could take from three to five years to complete. "The nuclear transfer of one species to another is not easy, and the lack of available panda eggs could be a major problem," Kraemer believes. "They will probably have to do several hundred transfers to result in one pregnancy. It takes a long time and it's difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort, "adds Kraemer, who is one of the leaders of the Missy plicity Project at Texas A&M, the first ever attempt at cloning a dog.
