rebound phenomenon

正确答案：D
在文章的第二段中，作者的两个反问句都是针对笑及笑时的表情的，其目的在于强调笑这种现象究竟是什么。所以本题的正确答案应当为D。

正确答案：B
47. [B] 意为：与商人的预想不符。或：不像商人预想的那样好。
第二段指出，官方的统计数字也并不怎么乐观，如果将制造业和服务业算在一起(lump... together)，1989年以来生产率平均增长了 1.2％，比前十年的平均指数略有增长；1991年后，生产率每年增长约 2％，是1978年至 1987年这十年平均指数的一倍多。然而问题是：最近显示出的增长部分是由商业领域里此时出现的正常的反弹造成的，因此，不能将它看作是更深层的（当指生产率）振兴的证据。正如财政部长鲁宾所说的那样，一方面，大量的商业神话似乎表明生产率的激增(leap)，另一方面，（官方的）统计数字又是另一番景象，二者之间存在着一个“差距”(disjunction)。定位到第二段的这几句：There is, as Robert Rubin, the treasury secretary, says, a "disjunction" between the mass of business anecdote that points to a leap in productivity and the picture reflected by the statistics.其意思是：正如财政部长罗伯特?鲁宾所说的，生产力发生飞跃的商业传奇与统计数字所反映的情况之间存在着一种“脱节”。商业传奇即是说大量的商业神话似乎表明生产率的激增(leap)。因此，可以得出结论，经济发展的实际情况和商人们所塑造的神话有脱节，即联系到了B 选项。
   A意为：排除了商业领域里出现的正常的反弹。此选项定位到了原文第二段中的 The trouble is that part of the recent acceleration is due to the usual rebound that occurs at this point in a business cycle，意思是：近年发生的生产力快速增长部分是由于商业周期通常到了这时候就会出现的反弹造成的。但是官方统计时并未排除此反弹，在原文中没有根据。原文只是说这个反弹是个 trouble，但是并未说找个 trouble被排除了。
   C意为：与商人预想的一致。这个与B 选项正好矛盾，参考B 选项的解释。
   D 意为：没有准确地反映经济的状况。该选项的说法太笼统了，虽然由原文得出了“脱节”的结论，但是请注意，是生产力发生飞跃的商业传奇与统计数字所反映的情况之间存在着一种“脱节”，而不是该官方统计与经济情况存在脱节。至少，原文并未说该统计不准确，而只是说该统计与商人们预料的不符。

二、      参考范文

Nowadays, more and more people, especially in big cities, become interested in buying lottery tickets. According to chart 1, averagely 70 percent of those polled in the survey, held in three big cities, claimed to have dreamed of winning the big prize of five-million yuan. 85 percent of those polled in Guangzhou had had such a dream, compared with 65 percent and 60 percent, respectively, in Beijing and Shanghai.

The attraction of buying lottery tickets is obvious. The winner can get the biggest profit for the future with only a small investment. It realizes the beautiful dream of every participant-to be richer and to improve living standards. As is shown in Chart 2, should they win a big lottery, 81.3% of people would buy a new house, 61.9% would buy a car, and 61.7% would save the money for the education of themselves or their kids. And a great proportion of people say they would put the money in the bank or use it for investment or touring. Despite all the attractions brought by the lottery buying, it has also come under criticism. Some regard it as a kind of gambling, which is a potentially addictive behaviour.

In my opinion, buying lottery tickets is not so bad as some people think. Instead, it is good for society by creating new jobs and representing an important source of income for charity and sports causes. Of course, it is not a means of making money for individuals we should encourage, because the result is hardly predictable. Therefore, we should take a positive but cautious attitude towards lottery buying behavior.
