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___________ Which of the following most logically completes the argument? 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 错选了C，答案给的A。A说女士比男士更可能做志愿活动，女士比男士活得长。这不是支持原文了么？可以题目不是应该驳斥吗？

求解

请问这道题为什么选B呀？

请问余数可以不是整数嘛？这道题怎么解释？

老师这个问题还没有解答 As引导的句子问题： 第一个句子as...as...是表示链接的内容程度一样吗，翻译起来感觉不太顺。the circumstances翻译成了这些规律和原则，哪些规律和原则？指代的是什么？此外with引导的是伴随状语？那as...as...作什么成分呢 第二个句子insofar查了是adv.在这个范围；到这个程度的意思。insofar as引导的是什么？insofar as the literature analysis is concerned怎么理解呢 第三个句子，四个as...第一个as意思是作为,第二个as意思也是作为？generally accepted as a race in any given region of ethnic competition怎么理解？第三和第四个as,表示和。。。一样，并列的是哪两个部分，什么和什么一样呢，后面the Chinese in California and the Jew in medieval Europe省略了什么

画线部分不理解。more...than..more后面的of the preindustrial European population比the 2 or 3 percent多？the preindustrial European population是不是应该放在investigate后面比较好

所以这一题c选择creating之所以修饰individual是因为这不是一个svo，+doing的形式所以采取的是就近修饰原则吗？

想问一下金老师，这道题c选择og解释里面说的是修饰individual不是reactions呀，您为啥说是修饰reactions呢

请问怎么从第二段看出来作者的观点是enable to enforce property right不是因为arbitrary 而是因为earlier parents often violated copyright law

我画粉色的这个是一个svo+doing形式吗 还是说它跟在that之后就不算一个完整句

请问什么情况下可以跳着修饰呀？
