单选题When people search online, they leave a trail that remains stored on the central computers of firms such as Google, Yahoo and Microsoft. Analyzing what we're looking for on the Web can offer a remarkable (51) into our anxieties and enthusiasms, UK writer and Internet expert John Battelle wrote on his blog, "This can tell us (52) things about who we are and what we want as a (53) ." Google's experimental service Google Trends, for example, compares the numbers of people searching for different words and phrases from 2004 to the present.

Other results are strikingly seasonal: people go shopping online for coats in winter and short pants in summer. The most fascinating possibility is that search data might help (56) people's behavior. When we search online for a certain brand of stereo system, we are surely indicating we're more (57) to buy that brand. Perhaps we search for a political candidate's name when we are thinking about (58) him or her. Maybe we even search for "stock market crash" or "recession" just before we start (59) our investments. This information could clearly be useful to a smart marketer--it's already how Google decides which (60) to show on its search results pages--or to a political campaign manager.

单选题There is much discussion today about whether economic growth is desirable. At an earlier period, our desire for material wealth may have been justified. Now, however, this desire for more than we need is causing serious problems. Even though we have good intentions, we may be producing too much, too fast. Those who criticize economic growth argue that we must slow down. They believe the society is approaching certain limits on growth. These include the fixed supply of natural resources, the possible negative effects of industry on the natural environment and the continuing increase in the world"s population. As society reaches these limits, economic growth can no longer continue, and the quality of life will decrease. People who want more economic growth, on the other hand, argue that even at the present growth rate there are still many poor people in the world. These proponents of economic growth believe that only more growth can create the capital needed to improve the quality of life in the world. Furthermore, they argue that only continued growth can provide the financial resources required to protect our natural surroundings from industrialization. This debate over the desirability of continued economic growth is of vital importance to business and industry. If those who argue against economic growth are correct, the problems they mention cannot be ignored. To find a solution, economists and the business community must pay attention to these problems and continue discussing them with one another.

单选题(78)Professor Martin's report says that children who attend a number of different schools, because their parents have to move around the country, probably make slow progress in their studies. There are also signs, says Professor Martin, that an unusually large number of such children are mentally (精神上) affected. The professor says, "It's true. My personal feeling is that children should stay in one school. However, our findings are based on research and not on any personal feelings that I or my assistants may have on the subject." Captain Thomas James, an Army lecturer for the past 20 years and himself a father of two, said, "I've never heard such rubbish. Taking me for example, no harm is done to the education of my children who change schools regularly---if they keep to the same system(系统) ,as in our Army schools. In my experience Army children--and I've known quite a few of them--are as well - adjusted(善于适应的)as any others, if not more so. What the Professor doesn't appear to appreciate is the fact that in such situations children will adapt(适应)much better than grown - ups." When this was put to Professor Martin, he said that at no time had his team suggested that all such children were backward or mentally affected in some way, but simply that in their experience there was a clear tendency (趋向). "Our findings show that while the very bright child can deal with regular changes without harming his or her general progress in studies, the majority of children suffer from constantly having to enter a new learning situation./
