※ 引述《sherry8701 (***)》之铭言： : 42. (32943-!-item-!-188;#058&007554) : 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 我写E 可以指点我的错误吗 谢谢! 原题因果：metabolism remain unchanged, burn fewer calories ---> ultimately regain weight (A) 取非後否定果，因为过重的人减轻体重後，能持续摄取少量的卡路里，则regain weight这个状况不会发生 (B)及(C)是与原题因果无关的比较；(D)及(E)是与原题因果无关的补充资讯 -- 讲到卡路里与减重的问题，fitness版的置底文真的是让人大推特推 --
