新GRE阅读逻辑题目翻译以及各个选项的解释.我选了E.正确答案是D
A researcher found that,in proportion to their body weights, children eat more carbohydrates than adults do. Children also exercise more than adults do. The researcher hypothesized that carbohydrate consumption varies in direct proportion to the calorie demands associated with different levels of exercise.

Which of the following, if true, most seriously undermines the researcher's hypothesis?

（A） More carbohydrates are eaten per capita in nations where the government spends more per capita on public exercise programs.

（B） Children who do not participate in organized sports tend to eat fewer carbohydrates than children who participate in organized sports.

（C） Consumption of increased amounts of carbohydrates is a popular tactic of runners preparing for long-distance races.

（E） Though carbohydrates are necessary for the maintenance of good health, people who consume more carbohydrates are not necessarily healthier.

一位研究员发现,与他们的体重成比例,儿童要比成人吃更多的碳水化合物.儿童同时也比成人运动得多.这位研究人员推断碳水化合物消耗与不同程度运动所需的热量成正比.
下面哪个陈述最严肃地削弱了这位研究人员的推论?
A.\x09政府按人头对公共锻炼计划进行投资,那里的人均碳水化合物消耗最大
B.\x09不参加组织的体育活动儿童比加组织的体育活动的儿童要少吃碳水化合物
C.\x09碳水化合物的消耗量增加是准备参加长跑爱好者普遍的策略
D.\x09长身体发育阶段比其他人更需要相对高的碳水化合物的消耗
E.\x09虽然为了维持良好的身体,碳水化合物是必需的,但是并非消耗了更多的碳水化合物的人就更健康.
显而易见,答案是D
