到麻烦。句中you表示泛指。

2.【答案】C"希望“邻近的脂肪消耗掉，在此符合语境；understand,know不

合逻辑，因为，即已”明白“，就不会不符合事实真相；believe表示的是人

的得一种看法，而看法有对有错。

脂肪消耗的情形。余者不合文意。

5.【答案】D余者不能概全

6.【答案】A根据常识可知，”不锻炼的肌肉会很快丧失力量。

7.【答案】D根据前一句“要重新获得力量需要48到72个小时可知，每隔

一天锻炼一次可保持正常水平的体力。”

8.【答案】A本句意思是为了一一体重，人们应该通过锻炼来出汗”。空格

处显然应该是“减少”。而不是“增加”或"“保持”，更不可能是“燃烧”。

10.【答案】B根据topreventoverheating可知，sweating的作用是降低

“不只是”，不合文意。本题应选nothingbut,全句的意思为“这（即sweating）

只是人体内水分的消耗”。

12.【答案】B意思是“一旦”，引起时间状语从句，余者不合文意。

13.【答案】A由Toloseweightyoushould…可推知,余者不在本节论及范

围之内。

14.【答案】Cthroughoutthebody遍及全身。余者不合文意。

15.【答案】Ahaveeffecton”对..产生影响”，合乎文意，合乎搭配。

16.【答案】C本节主要讲的是锻炼形式之----散步。另从最后一节中也能得

到暗示。

17.【答案】B根据常识和语境可知，“每天”（而不是某一天）至少得散步20分

钟。另everyday是形容词，不能作状语。

18.【答案】A与上一句中minimumamount形成木■比，if引导条件句。

19.【答案】C本节是上一节内容的继续，论述的仍是“锻炼"owalking不能

概括全面，应舍去。

20.【答案】C指出原因---“（运动）过量"。enough,much表意不清，muchtoo
