Question

【題目】Let's face it. No one drinks diet sodas for the taste. People drink diet sodas in the hope that it will help them lose weight or at least keep them from gaining it. Yet it seems to have exactly the opposite effect, according to a new study.

Researchers from the University of Texas said those who drank two or more diet sodas a day had waist size increases that were six times greater than those who didn't drink diet sodas. “What we saw was that the more diet sodas a person drank, the more weight they were likely to gain,” said Sharon Fowler.

The study was based on data from 474 participants in a large, ongoing research project, where the participants were followed for nearly 10 years.

While the findings are surprising，they also offer some explanations.

Nutrition expert, Melanie Rogers, who works with overweight patients in New York, has found that when patients are switched from regular to diet sodas, they don't lose weight at all. “We weren't seeing weight loss necessarily, and that was confusing to us,” said Rogers.

So why would diet soda cause weight gain? No one knows for sure yet，but it could be that people think they can eat more if they drink diet sodas, and so over－compensate(彌補) for the missing calories.

A related study found some sweeteners (甜味劑) raised blood sugar levels in some mice. “Data from this and other potential studies suggest that the promotion of diet sodas and artificial sweeteners may be risky,” said Helen P. Hazuda, professor at School of Medicine of the University of Texas. “They may be free of calories, but not of consequences.”

Answer 1

【答案】

【1】C

【2】B

【3】B

【解析】

試題分析：人們喝低糖飲料主要是為了減肥，或者至少是為了保持體重不再增加。但事實似乎是恰恰相反。有研究表明，喝低糖飲料的人往往會吃更多的東西。

【1】C細節(jié)理解題。根據(jù)“People drink diet sodas in the hope that it will help them lose weight or at least keep them from gaining it.”可知，人們喝低糖飲料是希望能夠幫助他們減肥，故選C。

【2】B推理判斷題。根據(jù)第二段“What we saw was that the more diet sodas a person drank, the more weight they were likely to gain”排除A；根據(jù)倒數(shù)第二段“people think they can eat more if they drink diet sodas, and so over－compensate(彌補) for the missing calories”可知B項正確，故選B。

【3】B猜測詞義題。根據(jù)“the promotion of diet sodas and artificial sweeteners may be risky”可知，低糖飲料和人工甜味劑可能是有害的，由此可知，They may be free of calories, but not of consequences.的意思是“低糖飲料和人工甜味劑可能不含卡路里，但是會帶來嚴(yán)重后果”，由此可知，劃線的they指代“低糖飲料和人工甜味劑”，故選B。
