Question

Putting in water fountains (飲水器) at schools, and teaching children about the health benefits of water, could reduce their risk of getting extra pounds, reports a new study that is published in the latest issue of the journal Pediatrics.
The findings are based on a survey in 32 elementary schools of two German cities, Dortmund and Essen. The researchers, led by Rebecca Muckelbauer, a nutritionist(營(yíng)養(yǎng)學(xué)家) at the Research Institute of Child Nutrition Dortmund, weighed about 3,000 children, and asked them about their beverage consumption(飲料消費(fèi)量).
At the beginning of the school year, the experts had water fountains added to 17 of the schools. The scientists also worked with teachers to carry out educational programs that promote the benefits of drinking water. In contrast to schools in the United States, there are very few schools in Germany that have water fountains.
At the beginning of the study, there were no big differences in the number of overweight children in the different groups. But by the end of the school year, children in the schools with water fountains were 31 per cent less likely to gain extra pounds, compared to kids who went to other schools, where water drinking was not encouraged.
Children in the schools with fountains increased their water consumption from about 3 up to 4 glasses a day, while those in the other schools continued to drink an average of 3 glasses. Over the research, the number of overweight kids upped from 384 to 385 out of 1,641 at the schools with water fountains. In comparison, the number of overweight kids at the other schools increased from 339 to 364 out of 1,309, Dr. Muckelbauer said.
The experts cannot make any final conclusions and explain why the students who were encouraged to drink water were less likely to gain extra weight. Dr. Muckelbauer noted that according to a few other studies, drinking of water increases the rate at which calories are burned, while some other research suggested that water may temporarily decrease appetite (食欲).

解析試題分析：本文主要通過在德國(guó)進(jìn)行的一個(gè)實(shí)驗(yàn)來告訴我們多飲水可以讓學(xué)生保持苗條身材。講述了這個(gè)研究的細(xì)節(jié)和最后的結(jié)論。
【小題1】D 推理題。根據(jù)文章第4段At the beginning of the study, there were no big differences in the number of overweight children in the different groups. But by the end of the school year, children in the schools with water fountains were 31 per cent less likely to gain extra pounds, compared to kids who went to other schools, where water drinking was not encouraged.作者把學(xué)期開始的數(shù)據(jù)和學(xué)期結(jié)束的數(shù)據(jù)進(jìn)行了比較，說明這個(gè)研究持續(xù)了一個(gè)學(xué)年。故D正確。
【小題2】B 推理題。根據(jù)文章最后一段1，2行The experts cannot make any final conclusions and explain why the students who were encouraged to drink water were less likely to gain extra weight.可知現(xiàn)在專家們無法得出一個(gè)最后的結(jié)論，也就是說要做更多的研究的調(diào)查。故B正確。
【小題3】C 主旨大意題。根據(jù)文章主題段第一段Putting in water fountains (飲水器) at schools, and teaching children about the health benefits of water, could reduce their risk of getting extra pounds,可知本文主要講述的是多飲水可以減少學(xué)生肥胖，可以讓學(xué)生保持苗條。故C正確。
