Q31

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.

谁能解释一下为什么是A么？

我选了C

谢谢

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.

即使志愿行为不能增长寿命，调查结果也会是我们期待的那样，因为——

A中说：女人这一群体天生就比男人这一群体长寿，而女性这一群体比男性群体天生更喜欢做志愿者。

我觉得这题因该是A。因为原文讨论的是志愿能不能使人寿命变长。

C说的是大脑里分泌这种东西会使人感到症状减轻。

所以A更加直接。C则需要添加减轻症状后会怎么样怎么样最终延长寿命。所以选A

vote for  A
