单选题The following questions present a sentence, part of which or all of which is underlined. Beneath the sentence, you will find five ways of phrasing the underlined part. The first of these repeats the original; the other four are different. If you think the original is best, choose the first answer; otherwise choose one of the others.

单选题1 Can animals have a sense of humor? Sally Blanchard, publisher of a newsletter called the Pet Bird Report, thinks a pet parrot may have pulled her leg. That's one explanation for the time her African gray parrot, named Bongo Marie, seemed to feign distress at the possible death of an Amazon parrot named Paco. It happened one day when Blanchard was making Cornish game hen for dinner. As Blanchard lifted her knife, the African gray threw back its head and said, "Oh, no! Paco!" Trying not to laugh, Blanchard said, "That's not Paco," and showed Bongo Ma rie that the Amazon was alive and well. Mimicking a disappointed tone, Bongo Marie said, "Oh, no," and launched into a hoarse laugh. Was the parrot joking when it seemed to believe the other bird was a goner? Did Bongo Marie comprehend Blanchard's response? Studies of African grays have shown that they can understand the meaning of words—for example, that red refers to a color, not just a particular red object. Parrots also enjoy getting a reaction out of humans, and so, whether or not Bongo Marie's crocodile tears were intentional, the episode was thoroughly satisfy ing from the parrot's point of view.

单选题W: You look like you are freezing to death. Why don"t you put this on? M: Thank you. It was so warm at noon, I didn"t expect the weather to change so quickly. Question: What do we learn from the conversation?

单选题In 1993, New York State ordered stores to charge a deposit on beverage (饮料) containers. Within a year, consumers had returned millions of aluminum cans and glass and plastic bottles. Plenty of companies were eager to accept the aluminum and glass as raw materials for new products, but because few could figure out what to do with the plastic, much of it wound up buried in landfills (垃圾填埋场). The problem was not limited to New York. Unfortunately, there were too few uses for second-hand plastic. Today, one out of five plastic soda bottles is recycled (回收利用) in the United States. The reason for the change is that now there are dozens of companies across the country buying discarded plastic soda bottles and turning them into fence posts, paint brushes, etc. As the New York experience shows, recycling involves more than simply separating valuable materials from the rest of the rubbish. A discard remains a discard until somebody figures out how to give it a second life—and until economic arrangements exist to give that second life value. Without adequate markets to absorb materials collected for recycling, throwaways actually depress prices for used materials. Shrinking landfill space, and rising costs for burying and burning rubbish are forcing local governments to look more closely at recycling. In many areas, the East Coast especially, recycling is already the least expensive waste-management option. For every ton of waste recycled, a city avoids paying for its disposal, which, in parts of New York, amounts to savings of more than $100 per ton. Recycling also stimulates the local economy by creating jobs and trims the pollution control and energy costs of industries that make recycled products by giving them a more refined raw material.
