31. GWD26-Q31此题要小心，不能一下子排除A,有时候靠感觉是不对的，而且关键要有理才行。

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. However, 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 throughout 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.

支持A

理解原文最后一句话最关键:即使volunteering不能增加人的寿命,那组统计数据也一样,没有变化,都是volunterring比没有voluntering的人长寿.说明这组人比较特殊.这些人寿命本来就长,不作voluntering寿命也长. A的意思是那组数据统计的是妇女,而他们通常比较长寿.所以拿这些人去统计,结果会是比平均成年人长命,即使扣除他们做的volunteering使他们长寿的因素. lawyer


尽管看了解析，但是脑子还是转不过来。。。求教！！！我觉得，最后一句话的意思是即使不考虑VOLUNTEER的因素，得到的结果也是应该一样的，但是A选项中还是涉及了VOLUNTEER呀？。。。。
领路angle。。。求NN！

Just break downthe information you have.
Help people→endorphins→longevity increased

Statistics：adults whoregularly engage in volunteer work helping others shows that they live longer,on average, than adults who do not volunteer
According the diagram above，it seems logically to infer volunteer can boost longevity

But the stimulus then stated！
statistic would be what we would expecteven if volunteering does not boost longevity
Then the seemingly right answer may indicatethere is something wrong with the statistics
（May be the longevity is causedby other factors just like A）

B：Atbest ,it seems to indicate that volunteering is beneficial，indicated by the increase.
 At worst, the rising number has no bearing on the argument.
C: stated a fact that already present bythe passage
D: obviously irrelevant
E：itpoint out a drawback of regular volunteering，but it doesnot account for why volunteering cannot improver longevity…（stress reduce lifespan？？？limited informationthat we cannot speculate）

不好意思，还是没有明白过来。。。能说的明白点吗？

哪里不明白？？、

简单来说...题目是想说volunteering应该是可以造成长寿的（就根据调查的那份资料来说）...但是得出来的结论却大相径庭，就是因为是其他原因造成了长寿（调查资料的有效性受到了质疑）所以攻击资料的有效性就能得出volunteering这个调查无效，自然而然就可以得出结论了，LZ好好理解它推理的逻辑链

是不是这个意思，A中的woman即使不做VOLUNTEER工作，她们也比男人长寿，因而她们的长寿不一定是VOLUNTEER造成而且是其他原因？A中的AND应该是表示并列的吧，而非women were much more likely to do regular volunteer work than men were所造成的
