GWD26-31汗。。。答案？？？

Q31（问问问）

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 women tend 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.

Answer:。。。

反正我觉得是a.答案是c。。。

这题有争议

lawyer认为是A

（认为statistic的结果是一个事实的反应）

理由如下：女人自然就比男人活的长，只不过他们更加投入于帮助别人，所以即使帮助别人不会助人活的长，结果也是一样，女人，那些更多的帮助别人的女人，活的就是长。从而推出更多帮助别人的人活的就是长。

=========================================

个人与lawyer有分歧

（认为statistic的结果是一个假象的反应）

理由如下：确实，帮助别人不会使人长寿，但是如果病症比较温和，帮助别人会掩盖一些疾病，得出帮助别人的人活的长的假象。

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

应该选A，男人和女人不都是成年人啊？如果女人（长寿的人）占支援者多的话，不就是支援者比不支援的人长寿吗?

而C答案，并没有说出为什么结论不成立，还能继续保持原来的现象（支援者中长寿的人更多）

at least for a time只能掩盖一时，难道长寿是一时就能看出来的吗，长寿是事实，并不是觉得。

疾病并不是死亡，比如一个人认为他的邻居（其实已经得了糖尿病）没有病，于是得出了结论他的邻居活的长？

他也不能保证他的结论正确把？长寿是科学家在这些观察对象死了之后得出的结论，并不是臆测

恩，再细细看来

如果选C，原文应该是live better 而不是live longer

这样A就没问题了

谢谢qianrene

我还是觉的A不对哦，

A女人比男人更爱帮助人，她们寿命一般也比男人长

这里不能排除“爱帮助人=》寿命更长”的可能性吧

如果加上前提“女人本来活得就比男人长”那么A就应该对了

请指正！

A说了两个东西

这两个东西排除两者之间的关系，也能得到统计的结果。

even if volunteering does not boost longevity, because
