单选题 The mass (大规模) production of cars was developed by Henry Ford in the 1920s and 1930s. At that time, Ford wanted to know how to build cars as quickly and cheaply as possible. It is only recently that people have begun to think about what happens to cars when we no longer use them. People have become slaves (奴隶) to the car over the last 60 years. As more new cars are built, the old ones are thrown away to become piles of waste. At the time when people are becoming more "green", that is, paying more attention to the environment, the problem of used cars is now more of an environmental nightmare (噩梦) than ever. The materials used to build cars—mainly steel, plastic, and rubber-are all long-lasting (持久的) and it takes hundreds of years for them to disappear naturally. For example, rubber tires have always been a big environmental problem, and it takes quite a lot of money to make an old rubber tire useful again.

单选题 In the United States, 30 percent of adult population has a "weight problem". Because they eat too much. Going back to America of 1910, we find that people were leaner (较瘦) than today, yet they ate more food. In those days people worked harder physically (体力上), walked more, used machine much less, and they didn't watch television. Several modern studies, moreover, have shown that fatter people do not eat more on average (平均) than thinner people. A 1979 study of 3, 545 London office workers showed that fat people ate less than slim (苗条) people. Studies also show that slim people are more active and have more physical activities than fat people. A study by a research group at Stanford University found the following interesting fact: The more the man ran, the greater loss (损耗) of body fat. The more the man ran, the greater more food he needed. So those who ran the most ate the most, yet lost greater amount (数量) of body fat.
