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 the feelings of well-being induced by endorphins can, at least for a time, mask C) the symptoms of various conditions and diseases, provided the symptoms are mild.
注意这里一个however,也就是说后面的内容和前面是不一样的,就是说试验结果不能证明help others导致长寿。而A答案却在进一步加强however前面的结论。所以A不对。
但是however后面说了,虽然不能证明能够导致长寿,但是还是可以得到the result we expect,也就是说help others (做志愿者)还是有好处的.C就是说了好处就是生病症状也mild一些,虽然不能证明长寿。
我支持C |
