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！作者: cckjenius 时间: 2011-5-11 21:04
请教一下。A项有点想不明白。
他说结婚的人参加对身体有害的运动，那么会decrease longevity，这个选项是怎么削弱的啊？
是说明了结婚对longevity有影响而削弱吗？
可是题目是说结婚cause to live longer，而不是结婚对longevity有影响啊？按照这个思路，应该要说结婚是人live longer才是削弱啊。。
求牛人帮忙解释下，这里实在想不通og 的解释。~~~作者: mop000 时间: 2011-5-15 07:41
我是这样理解的，这道题的argument主要是“this does not show that marriage caused people to live longer."
所以A选项说的是结婚导致人不运动，也就是marriage cause people NOT to live longer，那么就说明了结婚与长寿是有关系的，所以对其进行了削弱
因为B项，OG给的解释同样是削弱了结论，而B的确是结了婚的人比没结婚的更容易改掉坏习惯，这个是说的marriage cause people to live longer
所以不难看出，本题的削弱点是”结婚与长寿是有关系的“作者: yayajiaojef 时间: 2011-5-16 06:35
