问答题In this section, there is one passage followed by a summary. Read the passage carefully, and then complete the summary below by choosing a maximum of three words from the passage to fill in each of the blanks. Remember to write the answers on the answer sheet. Questions 1 to 5 are based on the following passage. Everyone knows about pollution in the environment. Water, air, and land are all polluted. This means that pollution is everywhere. Now, scientists are looking inside our bodies to find out about internal pollution. In 2003, the Environmental Working Group studied nine people to measure the chemicals in their bodies. These nine people had an average of 53 cancer-causing chemicals in their bodies. They also had an average of 62 chemicals that can damage the brain, and 55 that can harm babies in pregnant women. Even though a lot of chemicals were found in human bodies, the chemicals were found in small amounts. The amounts were small enough that they were probably not hurting the people. However, scientists are worried because most of these chemicals were created by humans. Most of these chemicals did not exist 75 years ago. This proves that we have not only polluted the world—we have polluted our own bodies! How does this pollution get into our bodies? We come into contact with many chemicals every day. For example, everyone uses soap, skin lotion, and shampoo. However, few people know that these products contain harmful chemicals, some of which may cause memory loss. Chemicals known as DEA (diethanolamine) and TEA (triethanolamine) may seep into the skin and stop us from absorbing a helpful nutrient called “choline”. Choline is a nutrient that plays a crucial role in the memory cell making process in the developing brain. Some people worry that every time we wash our hair, we are decreasing our memories. Everyone knows they should brush their teeth regularly, but recent research has shown that some toothpastes can cause cancer. Fluoride is a key ingredient in many toothpastes. However, studies show that fluoride does not really protect our teeth. In fact, fluoride has been connected with bone cancer and other diseases. While we are trying to save our smiles, we could be damaging our health. Women are probably exposed to more chemicals than men because they use more beauty products. Recently, harmful chemicals have been found in nail polish, hair spray, deodorant, and perfume. The chemicals are called “phthalates”. Studies on animals have shown that phthalates can damage the liver, the kidneys, and the lungs. Cosmetic companies say the amounts of phthalates in their products are safe, but consumer protection groups disagree. They say some women use so many products that the levels are actually high. So, the more women try to look beautiful, the more they could be harming their health. In a futuristic story by Ray Bradbury, a man found a pristine stream on a new planet. When he drank from the stream, he died! Why? His body was so polluted that pure water was a poison to him! Perhaps that is only science fiction, but it reminds us to take care of our bodies. We must find ways to reduce the pollution we absorb. Summary: Like our polluted environment, our bodies are no longer pollution-free. Scientists now know that there is pollution in our bodies. On 1 , we have 53 cancer-causing chemicals in our bodies. Even fluoride 2 with bone cancer and other diseases. Some common cosmetics contain small amounts of chemicals, which seep into our 3 when we use these products. They prevent us from absorbing the 4 our bodies need. So, it is 5 that we find ways to reduce the amount of chemicals in our bodies. We should remind our friends and families to take care of their bodies.

问答题For all the talk of his sustained adolescence, no performer made a more compelling entrance into manhood than Michael Jackson did with the release of his 1979 album, “Off the Wall” just a couple of weeks before his 21st （1）____（day）. It was all the more stunning because we had watched him during his （2） child____ and adolescence. He wasn’t an apparition rising out of obscurity, like Elvis Presley. To become who he was in “Off the Wall,” he had to annul—if not destroy—the performer he had been in the Jackson 5. However, the change was （3）____（organ） as well as deliberate. Michael Jackson grew into his body, and out of that new body emerged wholly new ideas of what pop music, and the （4） move ____ it generates, were. It can be hard to remember now, 30 years later, just how ubiquitous the hits from that album, especially “Rock with You,” really were. In soul, in rock ‘n’ roll, and in pop, there is a long tradition of men singing in high voices, the height of the voice suggesting the pitch of the singer’s fervour. Michael Jackson made the sweetness of that high voice guttural and （5）____（demand）. He showed that it was rooted in his feet and hips and hands. He re-sexualized it in a way that you could never really mistake—then—as androgynous. Very few artists—certainly very few child stars—have ever redefined themselves as thoroughly or as （6）____（success） as Michael Jackson did. His second act was better than any number of first acts put together. The uncanny thing wasn’t just his physical transformation, or his hypnotic new ability to move. It was the certainty of “Off the Wall” and its sequel “Thriller” that this was the music we wanted to hear. He knew, too, that this was a music we wanted to （7）____（visual）, to see formalised and set loose in dance. In a sense, he was loosing his transformation upon the rest of us, expecting us to be caught up in the （8） excite____ the music caused in him, and we were. Michael jackson came to be synonymous with transformation—ultimately, with an eerie stasis that comes from seeking transformation all the time. The alchemy of change worked longer and（9）____（well） for him—through the ’80s and into the early ’90s—than it has for almost any other artist. Yet somehow all the changes always take us （10）____ to the album in which Michael Jackson grew up.

问答题Within a very short time of coming back into power the present government had taken steps to stabilize the position. First of all, we applied ourselves to identifying the root causes of our national ailments, examining contemporary evidence and refusing to be slaves to outmoded doctrinaire beliefs. Secondly we embarked on a reasoned policy to ensure steady economic growth, the modernization of industry, and a proper balance between public and private expenditure. Thirdly by refusing to take refuge—as the previous Government had continually done in the preceding years—in panic-stricken stop-gap measures, we stimulated the return of international confidence. As a result of those immediate measures, and aided by the tremendous effort which they evoked front our people who responded as so often before to a firm hand al the helm, we weathered the storm and moved on into calmer waters and a period of economic expansion and social reorganization.
问答题Since a particular bookstore happens to resemble a supermarket anyway, the inescapable, though perhaps unintended, message is that books are consumable items, meant to be devoured and forgotten, like potatoes or pizza. The implied inclusion of books among the world’s perishable goods is hardly made more agreeable by the reflection that increasing numbers of books these days do seem to be written with just such consumption in mind, and that most bookstores have become little more than news stands for hard cover publications of this sort, which are merchandised for a few weeks—sometimes only as long as they remain on the best-seller lists—and are then retired to discount store (those jumbled graveyards of books, so saddening to the hearts of authors)shortly before dropping out of print altogether. Books that are planned for rapid oblivion probably make some kind of economic sense to publishing houses, but as contribution to literature they amount to a contradiction in terms.

The average American changes his or her job nine or ten times during his or her working life.
