Question

17．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．"

分析 文章讲述了喝苏打水不能让人减肥，反而可能让人更胖，并分析了原因．

解答 33．C 细节理解题．根据第一段People drink diet soda in the hope that it will help them lose weight or at least keep them from gaining it．人们喝低糖汽水，希望能帮助他们减肥，或者至少让他们不喝减肥药．可见目的是为了减肥，所以答案选C．
34．B 细节理解题．根据文章倒数第二段it could be that people think they can eat more if they drink diet soda，and so over-compensate for the missing calories．人们可能会认为，如果他们喝低糖汽水，他们可以吃得更多，从而弥补了卡路里的不足．所以答案 选B．
35．C 猜测词义题．根据文章最后一段可知They 指代前面的提及的diet sodas and artificial sweeteners．减肥苏打和人造甜味剂may be free of calories，but not of consequences．"可能没有卡路里，但没有效果．所以答案选C．
