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____________.

真题, 有争议。。。

此题大家选什么? 我选A,但另有版本答案是C


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 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.



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.

我的想法:


当人们从事帮助他人的活动时,他们的大脑会分泌一种叫endorphins的物质,它是一种天然吗啡,可以在人体内产生一种“欣快感”。已有意见称定期分泌的endorphins可以延长人的寿命。而且一项统计称定期从事志愿工作去帮助他人的那些人活得更长一些。但是,即使那些志愿者的寿命不因此延长,我们也仍然会预期那此统计的结果出现。因为:



A 说:社区调研显示,女人比男人更愿意去做志愿者(也就是说志愿者中,女人比男人多,女人的状况更有代表性),而女人本来就比男人的寿命要常(所以即使不是由于Endorphins 的作用,以女人为代表的志愿者人群的寿命也会比较长。)


选A

我也来讨论一下


文章要求就“对志愿者的统计数字并不说明他们长寿”做出解释


A虽然说了女人和男人的比较,但是并不能引申到做志愿者也不一定长寿


反而说女人愿意做志愿者,而且女人做志愿者比例大,这样的话,总体人群的长寿可能性不是更大吗?


而C意思说在不同条件,疾病下,这个因为做志愿者而让人长寿的物质就比较mild了。


罗门弄技了

弄一下小斧头。


题中的2个现象。题目要求对这两种略微矛盾的现象给出解释。


1。 经常帮助别人的比不经常的活的长。


2。虽然长乐,但这种寿命的延长并没有显著的增加。


A是仅对1进行了论述,可以看成是对一的一个弱的加强,但它没有解释2。而且,A比较more likely to volunter和 less likely to,和原文的regularly和nor regularly好像不太一样,至少我感觉不是很爽 。


B我读不懂,既然5个选项中没有无关选项,基于ETS对无关选项的热爱,我暂且认为它是无关。


C,一看就爽,他因导致。虽然句子语法好像不太通,但是ETS更爱它。


D,题目是regularly 和长寿的联系,既然D说的是rare regular, 它是out of scope.


E,惋惜呀,本来挺好一个答案,可是那个some。。。。。而且,E是indirect,原文没有提及under stress和寿命的关系。


open for discussion!

以下是引用sensornet在2005-6-13 0:57:00的发言:

弄一下小斧头。


看2楼的帖子,有两个感觉,一对题意的理解好像不是很全,二可能掺进了个人的主观联想。题中提到现象的区别在于,live longer和boost longevity.我对你说的女人比男人的寿命就长感到很大困惑,不但没在原题中找到类似信息,而且个人感情受到了很大刺激因为我是男性。


二楼所说的女人寿命比男人长是从选项A里面说的。

呵呵。谢谢楼上,以改过。你说ETS咋那样,干啥说人家短寿呢

但问题中说的是


that statistic would be what we expect 就算他们没有真的长寿


而不是说that result之类的


所以我的理解是: 因为本来就是女比男长寿,又因为女的志愿者比男志愿者多,所以不管做好事有没有使人长寿,那个“志愿者平均寿命比非志愿者平均寿命长的数据”would be what we would expect.


more discuz plz..
