Researchers havefound that when very overweight people, who tend to have relatively lowmetabolic rates, lose weight primarily through dieting, their metabolismsgenerally remain unchanged. They willthus burn significantly fewer calories at the new weight than do people whoseweight is normally at that level. Such newly thin persons will, therefore, ultimatelyregain weight until their body size again matches their metabolic rate.
The conclusion of theargument 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 fewercalories than do people whose normal weight is at that level.
(B) The metabolisms of people who are usually notoverweight are much more able to vary than the metabolisms of people who havebeen very overweight.
(C) The amount ofcalories that a person usually burns in a day is determined more by the amountthat is consumed that day than by the current weight of the individual.
(D) Researchers havenot yet determined whether the metabolic rates of formerly very overweightindividuals 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 gainingweight as they do losing it.
正确答案 a
但是我觉得A是削弱
我理解的题干是:因为胖子的新陈代谢率比常人低,所以即使胖子通过节食瘦到一个新体重他的新陈代谢率还是原来的。所以最终还是会胖回去。
A选项说Relatively few是说相当少的通过节食瘦下来的胖子会低正常人消耗更少的卡路里,意思就是大部分新瘦下来的胖子不会比正常人消耗更少的卡路里。
这样不是正好相反吗 展开

研究者发现超重的人通常有比较低的M rate,他们减重主要通过节食,但是他们的M rate不会改变。他们因此燃烧更少的卡路里在他们新的体重,比那些正常体重的人。这种重新瘦下来的人,因此,最终增加他们的重量,直到他们的体型重新接近他们的M rate。
题目读成这样应该是没有问题的。题目大概就是说尽管胖子节食瘦下来了,但是M rate不会变,因此这帮悲催的家伙最后还是会胖回去。
题目问假设,也就是最后一句话(结论)是建立在以下哪个假设之上的。取非削弱结论即是正确答案。
A选项说,胖子们瘦下来后仍然节食。(胖子节食瘦下来后坚持食用相当低卡路里的食物,比那些体重正常的家伙)
此选项取非显然削弱题目结论。(取非为:胖子节食瘦下来后胡吃海喝 ----> 【就算不去考虑那个M rate】他们自然又胖回去)
也就是说,尽管胖子(通过调整饮食结构)瘦下来后,【且继续食用低卡路里的食物 --> 此为A选项的假设】(但是由于M rate不会改变),仍然会变胖。
这里可以看到,A选项完美的防止了补刀情况的发生,简直NICE。
PS:看了下你的问题,貌似你对A选项的理解有误=。= 这是要加强英文能力的节奏。

relatively few people tend to consume fewer calories 是表达的继续节食的意思吗
追答
我SX了,my fault,sorry!
A选项应该是几乎没有胖子在瘦下来后仍然会比体重相当的人消耗更少的热量,即几乎全部胖子瘦下来后,这帮人消耗的热量大于等于那些跟他们体重相当的人消耗的热量。好比说,胖子瘦下来后,为了保持身材,每天做1000个仰卧起坐,而隔壁邻居老王有人鱼线,每天却只做800个。
那么问题来了,既然胖子们没有消耗了比人家少的热量,为何还会悲催的胖回去?
