背景:help others---->releases endorphins regular release of endorphins---->longevity 推理链:adults who regularly engage in volunteer work---->live longer than non volunteer
关键Focus on the conclusion.结论说,就算志愿工作不能使人长命,数据的结果都是志愿者比非志愿者长命,问为什么?
这里,实际上要解释“不是volunteer work导致adults长寿”。 调整一下原文语序: However, even if volunteering does not boost longevity, that statistic would be what we would expect, because---. Women本身就更多地做志愿者,同时,women天生比men长寿, 由此,不是志愿工作让一部分人更长寿,而是,women与men天生的差别所致。
passage 说的是help others can release endorphins, and then increase longevity. Statistic 说的是volunteer 更长寿。 结论要是我们证明的是,即使volunteer不会令人长寿,volunteer还是比非volunteer更长寿的。A就完全说明了这一点啦~~就是volunteer比非volunteer长寿而且与endorphins无关(因为A没提到en吖~~)
正是因为最后一句话 even if volunteering does not boost longevity 才选的 A 题目说讨论的是 志愿工作会否令人长寿,并提出了统计数据说是。但作者其实是反对统计数据这个论据的,However, that statistic would be what we would expect even if volunteering does not boost longevity, 其实就是作者的目的——否定以上统计数据的有效性。 因为作者提出做志愿工作的女生比男生多,而女生本来就比男生长寿,所以统计数据的长寿可能与志愿工作根本无关。—— A 题目的关键是掌握作者的立场,作者是认为统计数据是无效的
