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（彌補(bǔ)） 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

分析 文章講述了喝蘇打水不能讓人減肥，反而可能讓人更胖，并分析了原因．

解答 33．C 細(xì)節(jié)理解題．根據(jù)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．人們喝低糖汽水，希望能幫助他們減肥，或者至少讓他們不喝減肥藥．可見目的是為了減肥，所以答案選C．
34．B 細(xì)節(jié)理解題．根據(jù)文章倒數(shù)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．人們可能會(huì)認(rèn)為，如果他們喝低糖汽水，他們可以吃得更多，從而彌補(bǔ)了卡路里的不足．所以答案 選B．
35．C 猜測(cè)詞義題．根據(jù)文章最后一段可知They 指代前面的提及的diet sodas and artificial sweeteners．減肥蘇打和人造甜味劑may be free of calories，but not of consequences．"可能沒有卡路里，但沒有效果．所以答案選C．

點(diǎn)評(píng) 本文考查細(xì)節(jié)題為主，細(xì)節(jié)題可以在文章中直接找到與答案有關(guān)的信息？或是其變體．搜查信息在閱讀中非常重要它包括理解作者在敘述某事時(shí)使用的具體事實(shí)、數(shù)據(jù)、圖表等細(xì)節(jié)信息．在一篇短文里大部分篇幅都屬于這類圍繞主體展開的細(xì)節(jié)．做這類題一般采用尋讀法？即先讀題，然后帶著問題快速閱讀短文，找出與問題有關(guān)的詞語(yǔ)或句子，再對(duì)相關(guān)部分進(jìn)行分析對(duì)比，找出答案．
