5月6日后GMAT换库后，小编为大家收集整理5月份的GMAT逻辑机经，这篇是关于运动员喝营养剂的文章，分享给大家，希望对大家有所帮助，仅供参考。

　　【本月原始】

　　一名教练说，服用营养补充剂的运动员在比赛中获胜的概率较大，因此推断营养补充剂对运动员很有效。

　　问weaken这个推理的选项。

　　其中一个选项是：喜欢服用营养补充剂的这些运动员本身就是比较强、比较有希望获胜的。我选了这个

　　Dennis：因簡單的倒因為果說是喝營養劑讓勝率大其實是勝率大都愛喝營養劑

　　【考古题干】

　　【V1】一名教练的调查发现使用营养品的运动员更容易产生好成绩，结论营养品是有效的。削弱。

　　楼主答案：此调查没有考虑到那些即使不用营养品就能去的好成绩的运动员往往更倾向于使用营养品。(740狗主确认此答案)

　　【猜想逻辑链】-zkybq

　　前提：用营养品导致有好成绩

　　结论：营养品有效

　　预测答案：此调查没有考虑到那些即使不用营养品就能去的好成绩的运动员往往更倾向于使用营养品。(削弱前提)

　　【附类似推理一道题】(GWD-26-Q31):-zkybq

　　Which of the following most logically completes the argument??

　　When people engage in activities that help others ,their brain releases endorphins,

　　the brain’s natural opiates, which induce in people a feeling of well-being. It has

　　been suggested that regular release of endorphins increases people’s longevity.

　　And a statistic on adults who regularly engage in volunteer work helping others

　　shows that they live longer, on average, than adults who do not volunteer. How-

　　ever, that statistic would be what we would expect even if volunteering does not

　　boost longevity, because .

　　A. in the communities studied, women were much more likely to do regular

　　volunteer work than men were, and womentend to live longer than men do.

　　B. the number of young adults who do regular volunteer work is on the increase

　　C. the feelings of well-being induced by endorphins can, at least for a time, mask

　　the symptoms of various conditions and diseases, provided the symptoms are

　　mild.

　　D. it is rare for a person to keep up a regular schedule of volunteer work through-

　　out his or her life.

　　E. Some people find that keeping a commitment to do regular volunteer work

　　becomes a source of stress in their lives.

　　以上就是关于运动员喝营养剂的GMAT逻辑机经的全部内容，考生朋友可以有选择的看看，最后需要提醒各位的是，机经虽然会对我们解题有所帮助，但是在考场中即使题目很像也要避免秒选，最后祝大家都能考出好成绩。
