诚问:OG12th--119

题目如下
119. It is true of both men and women that those who
marry as young adults live longer than those who
never marry. This does not show that marriage causes
people to live longer, since, as compared with other
people of the same age, young adults who are about
to get married have fewer of the unhealthy habits that
can cause a person to have a shorter life, most
notably smoking and immoderate drinking of alcohol.
Which of the following, if true, most strengthens the
argument above?
(A) Marriage tends to cause people to engage less
regularly in sports that involve risk of bodily
harm.
(B) A married person who has an unhealthy habit is
more likely to give up that habit than a person
with the same habit who is unmarried.
(C) A person who smokes is much more likely than a
nonsmoker to marry a person who smokes at
the time of marriage, and the same is true for
people who drink alcohol immoderately.
(D) Among people who marry as young adults, most
of those who give up an unhealthy habit after
marriage do not resume the habit later in life.
(E) Among people who as young adults neither drink
alcohol immoderately nor smoke, those who
never marry live as long as those who marry.

答案选E
OG的解释 by showing that a person who gets married young tends to live about
as long as one who had been living an equally healthy lifestyle as a young adult but who
never got married, the argument is greatly strengthened.看不懂……
对于A-E的选项解释如下,可是还看不懂……
A To the extent that risk of bodily harm decreases longevity, this weakens rather than strengthens
the argument.
B Th is option, too, weakens the argument rather than strengthens it, since it suggests that marriage
does indeed enhance one’s longevity.
C Even if a person with unhealthy habits who marries is more likely to wind up with a spouse with
unhealthy habits than is a person with healthy habits who marries, that tells us nothing about
whether the average person who gets married gets a boost in longevity.
D Th is option does not tell us whether it is also true of those who never marry that most of them
who give up an unhealthy habit as a young adult ever resume that habit later in life. Th us, by
itself, this option has no bearing on the strength of the argument.
E Correct. Th is strengthens the argument against the causal connection between marriage and
longevity by showing that the longevity diff erence disappears when the longevity of those who
marry young is compared with young adults with similar health habits who will never marry.
大家鄙视我的智商吧,真的不明白这道题了,望NN解答!多谢!

不知道楼主究竟哪里不太明白,就贴个题干解释吧

题干:因为准备结婚的人们不良生活习惯少,所以结婚了的人寿命长。问加强

A结婚让人们更加没有规律地参加对身体有危害的运动。
OG解释:这个选项削弱。因为结婚让人们更加没有规律地参加运动,说明运动的不是多了,而是少了,说明结婚了会导致身体不健康。有一点 注意:所有运动都有可能对身体造成伤害,但大部分都是好的,毕竟是sports。

B有不良生活习惯的结了婚的比不结婚的有不良习惯的更容易戒掉。
OG:削弱了。我感觉这里说的不太对,应该是弱加强,但是和题干结论不一样, 是要结婚的年轻人,而这里说结了婚blabla。

C抽烟的娶抽烟的,酗酒的娶酗酒的。
OG:选项没有说明是否结了婚的人普遍都有寿命增长。

D:在结了婚的年轻人中,大部分戒了坏习惯都不再犯了。
OG:这个选项没有说明从没有结婚的大部分年轻人戒掉了坏习惯后来又犯是否是真的。

E:不抽烟不酗酒的年轻人中不结婚也活的和结了婚的一样长。
OG:正确。通过说明当不结婚且没有坏习惯的人与结婚的年轻人的寿命区别消失了的时事反对了结婚和长寿之间的因果联系。

这题主要看题干的本质:寿命长于结婚没关系,关键是倾向于结婚的人都有好习惯。
还有一道说取消监狱课程的题,也有类似的理由,上课的犯人出来犯罪少,并不是因为上课的原因,而是倾向于上课的人不大会犯罪。

关于B项OG的解释还请NN指点~~

我对B选项的理解一部分和你是相同的。
另一个B错的原因是因为题目中强调的是“结婚对于长寿没有影响”,而这个选项说的是“结婚对于长寿有影响”。

TOP

关于B的解释,赞同楼上的大侠,B说结婚对寿命有影响,所以削弱
