单选题After the violent earthquake that shook Los Angeles in 1994, earthquake scientists had good news to report. The damage and death toll could have been much worse. More than 60 people died in this earthquake. By comparison, an earthquake of similar. intensity that shook America in 1988 claimed 25,000 victims. Injuries and deaths were relatively less in Los Angeles because the quake occurred at 4:31 a. m. on a holiday, when traffic was light on the city's highways. In addition, changes made to the construction codes in Los Angeles during the last 20 years have strengthened the city's buildings and highways, making them more resistant to quakes. Despite the good news, civil engineers aren't resting on their successes. Pinned to their drawing boards are blueprints for improved quake-resistant buildings. The new designs should offer even greater security to cities where earthquakes often take place. In the past, making structures quake-resistant meant firm yet flexible materials, such as steel and wood, that bend without breaking. Later, people tried to lift a building off its foundation, and insert rubber and steel between the building and its foundation to reduce the impact of ground vibrations. The most recent designs give buildings brains as well as concrete and steel supports, called smart buildings, the structures respond like living organisms to an earthquake's vibrations. When the ground shakes and the building tips forward, the computer would force the building to shift in the opposite direction. The new smart structures could be very expensive to build. However, they would save many lives and would be less likely to be damaged during earthquakes.

单选题Which of the following did the author provide a guardedly optimistic view?

单选题Language learning begins with listening. Individual children vary greatly in the amount of listening they do before they start speaking, and late starters are often long listeners. Most children will "obey" spoken instructions some time before they Can speak, though the word "obey" is hardly accurate as a description of the eager and delighted cooperation usually shown by the child. Before they can speak, many children will also ask questions by gestures and by making questioning noises. Any attempt to trace the development from the noises babies make to their first spoken words leads to considerable difficulties. It is agreed that they enjoy making noises, and that during the first few months one or two noises sort themselves out as particularly indicative of delight, distress, sociability, and so on. But since these cannot be said to show the baby's intention to communicate, they can hardly be regarded as early forms of language. It is agreed, too, that from about three months they play with sounds for enjoyment, and that by six months they are able to add new sounds to their store. This self-imitation leads on to deliberate imitation of sounds made or words spoken to them by other people. The problem then arisen so to the point at which one can say that these imitations can be considered as speech. It is a problem we need not get our teeth into. The meaning of a word depends on what a particular person means by it in a particular ,situation and it is clear that what a child means by a word will change as he gains more experience of the world. Thus the use,at say seven months, of "mama" as a greeting for his mother cannot be dismissed as a meaningless sound simply because he also uses it at other times for his father, his dog, or anything else he likes. Playful and apparently meaningless imitation of what other people say continues after the child has begun to speak for himself. I doubt, however; whether anything is gained when parents cash in on this ability in an attempt to teach new sounds. (370w)

单选题 The process of gaining or losing weight can be explained by comparing your body to your car. Both run {{U}}(56) {{/U}} fuel, food for your body and gasoline for your car. Both {{U}}(57) {{/U}} that fuel, first into heat, then energy, some of {{U}}(58) {{/U}} is used to do work, and some emitted as waste. And {{U}}(59) {{/U}} your car uses more energy when the engine is racing than when it is idling, {{U}}(60) {{/U}} does your body use more energy when you are working hard than {{U}}(61) {{/U}} you are resting. For the purpose of this comparison, {{U}}(62) {{/U}}, there is one significant difference between them. Your car cannot store fuel by turning it into {{U}}(63) {{/U}} else; all gasoline not {{U}}(64) {{/U}} remains as gasoline. But your body stores {{U}}(65) {{/U}} energy as fat. When the gas tank is {{U}}(66) {{/U}} empty, the car won't run; but your body can burn fat to provide more energy. Therefore, if you want to gain weight, you must do {{U}}(67) {{/U}} of two things: eat more calories (units of heat, therefore energy), or use less through {{U}}(68) {{/U}}. If you want to lose weight, you do the {{U}}(69) {{/U}}, decrease your intake of calories or increase the amount of energy you spend. There is {{U}}(70) {{/U}} way. Gaining or losing weight is always a relation between intake and output of potential energy.

单选题{{B}}Passage Three{{/B}} In 1998, consumers could purchase virtually anything over the Internet. Books, compact discs, and even stocks were available from World Wide Web sites that seemed to spring up almost daily. A few years earlier, some people had predicted that consumers accustomed to shopping in stores would be reluctant to buy things that they could not see or touch in person. For a growing number of time-starved consumers, however, shopping from their home computer was proved to be a convenient alternative to driving to the store. A research estimated that in 1998 US consumers would purchase $ 7.3 billion of goods over the Internet, double the 1997 total. Finding a bargain was getting easier owing to the rise of online auctions and Web sites that did comparison shopping on the Internet for the best deal. For all the consumer interest, retailing in cyberspace was still a largely unprofitable business, however. Internet pioneer Amazon.com, which began selling books in 1995 and later branched into recorded music and videos, posted revenue of $ 153.7 million in the third quarter, up from $ 37.9 million in the same period of 1997. overall, however, the company's loss widened to $ 45.2 million from $ 9.6 million, and analysis did not expect the company to turn a profit until 2001. Despite the great loss, Amazon.com had a stock market value of many billions, reflecting investors' optimism about the future of the industry. Internet retailing appealed to investors because it provided an efficient means for reaching millions of consumers without having the cost of operating conventional stores with their armies of salespeople. Selling online carried its own risks, however. With so many companies competing for consumers' attention, price competition was intense and profit margins thin or nonexistent. One video retailer sold the hit movie Titanic for $ 9.99, undercutting (削价) the $ 19.99 suggested retail price and losing about $ 6 on each copy sold. With Internet retailing still in its initial stage, companies seemed willing to absorb such losses in an attempt to establish a dominant market position.
