Cloze Test 28
1.【答案】D
【解析】因为大部分人不知道如何正确锻炼，所以，人们在训炼时常会遇到麻烦。句中you表示泛指。
2.【答案】C
【解析】“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。
3.【答案】B
【解析】下一句中再现了burn这一词。
4.【答案】C
【解析】truth本意为“真理”，此处引申为“事实”——指实际锻炼时脂肪消耗的情形。余者不合文意。
5.【答案】D
【解析】余者不能概全
6.【答案】A
【解析】根据常识可知，“不锻炼的肌肉会很快丧失力量。
7.【答案】D
【解析】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
【解析】本句意思是“为了——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”。
9.【答案】B
【解析】表示对该节首句看法的否定。首句看法的错误性可从下文推知。
10.【答案】B
【解析】根据to prevent over heating可知，sweating的作用是降低体温。
11.【答案】C
【解析】loss是名词，故前面不能填连接副词how和why；more than“不只是”，不合文意。本题应选nothing but，全句的意思为“这(即sweating)只是人体内水分的消耗”。
12.【答案】B
【解析】意思是“一旦”，引起时间状语从句，余者不合文意。
13.【答案】A
【解析】由To lose weight you should…可推知，余者不在本节论及范围之内。
14.【答案】C
【解析】throughout the body遍及全身。余者不合文意。
15.【答案】A
【解析】have effect on“对……产生影响”，合乎文意，合乎搭配。
16.【答案】C
【解析】本节主要讲的是锻炼形式之一——散步。另从最后一节中也能得到暗示。
17.【答案】B
【解析】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
【解析】与上一句中minimum amount形成对比，if引导条件句。
19.【答案】C
【解析】本节是上一节内容的继续，论述的仍是“锻炼”。walking不能概括全面，应舍去。
20.【答案】C
【解析】指出原因——“(运动)过量”。enough，much表意不清，much too后应接其它词。
