Question

【题目】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(弥补) for the missing calories.

A related study found some sweeteners (甜味剂) 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】

试题分析：人们喝低糖饮料主要是为了减肥，或者至少是为了保持体重不再增加。但事实似乎是恰恰相反。有研究表明，喝低糖饮料的人往往会吃更多的东西。

【1】C细节理解题。根据“People drink diet sodas in the hope that it will help them lose weight or at least keep them from gaining it.”可知，人们喝低糖饮料是希望能够帮助他们减肥，故选C。

【2】B推理判断题。根据第二段“What we saw was that the more diet sodas a person drank, the more weight they were likely to gain”排除A；根据倒数第二段“people think they can eat more if they drink diet sodas, and so over－compensate(弥补) for the missing calories”可知B项正确，故选B。

【3】B猜测词义题。根据“the promotion of diet sodas and artificial sweeteners may be risky”可知，低糖饮料和人工甜味剂可能是有害的，由此可知，They may be free of calories, but not of consequences.的意思是“低糖饮料和人工甜味剂可能不含卡路里，但是会带来严重后果”，由此可知，划线的they指代“低糖饮料和人工甜味剂”，故选B。
