OG-173-->携隐修改标题（OG逻辑173，请教一下）

173. Researchers have found that when very overweight people, who tend to have relatively low metabolic rates,
lose weight primarily through dieting, their metabolisms generally remain unchanged. They will thus burn
significantly fewer calories at the new weight than do people whose weight is normally at that level. Such
newly thin persons will, therefore, ultimately regain weight until their body size again matches their metabolic
rate.
The conclusion of the argument above depends on which of the following assumptions?
(A) Relatively few very overweight people who have dieted down to a new weight tend to continue to consume
substantially fewer calories than do people whose normal weight is at that level.
(B) The metabolisms of people who are usually not overweight are much more able to vary than the metabolisms of
people who have been very overweight.
(C) The amount of calories that a person usually burns in a day is determined more by the amount that is
consumed that day than by the current weight of the individual.
(D) Researchers have not yet determined whether the metabolic rates of formerly very overweight individuals can be
accelerated by means of chemical agents.
(E) Because of the constancy of their metabolic rates, people who are at their usual weight normally have as much
difficulty gaining weight as they do losing it.

答案A，一直想不通

原文说了这莫基建事情::一种人减不减肥, M那个东西变不变,烧不烧C

A说一些人烧不烧C有关先留下

B说M这个东西变化,有关,那也留下

C说C的数量受什莫因素决定,原文没说,无关选项

D说M能不能被加速,原文没说,无关选项

E说仁减肥容不容易,,原文没说,无关选项

a 和B 逻辑求非就能得出答案.

不止讲得是否清楚,如果不明白,请告诉我

173题新问：

题干：新陈代谢率不变 =〉因节食体重减轻者会恢复体重

我知道A是对，即因节食体重减轻者，肯定不能保持，会继续吃。

但是，我不明白C为什么错。（OG说，数量无关）

C: 消耗量由摄入量决定，而非体重。那不就等于说新陈代谢率（消耗量/摄入量）不变吗？反之，如果随体重变化，则新陈代谢率变了，题干前提被否定，命题不成立。

请赐教！

A读完后，一取非，就能推出原文的结论。

然后扫一下期于选项，就用无关和有关排除就可以了。C是无关的，对结论没有任何作用。

不知道说清楚了没。

A得取非我还是不是很理解，能不能请楼主再帮我解释一下

A的意思：

几乎没有减肥瘦下来的人可以吃得比原来就在这个比较瘦的水平上的人更少。

由于他们的代谢水平比正常人低，所以吃一样多的东西会长胖。

这道题我选的D

主要是因为掐时间做题的关系

A一眼看去没看懂，觉得太费解，跳过

B讲的是瘦子可以改变新陈代谢，无关，排除

C讲的是燃烧的能量取决于摄入的能量，错，排除

D讲的是如果没有加速新陈代谢的方法，这个选项我认为是对的，因为如果有了加速新陈代谢的方法，胖子们就可以燃烧更多的能量，减肥后就不会反弹，只有在没有这种方法的前提下，胖子们减肥后才会反弹，题干中的结论才能成立，因此我选择它

E项就不看了

看了答案选A之后，我又认真读了A项，发觉A也是对的——胖子在减肥后如果不继续控制能量的摄入量，就会反弹，只有在A项的前提下，才不会反弹。

句子确实较难读懂，如果掐时间做题的话，我最怕遇上这种选项，一遇上这道题基本就死了一半了。

比较A和D，我觉得还是应该选A，因为毕竟D是引入了一个题干中没有提到的东西。

各位NN以为然否？
