Answer 1

分析 本文主要讲述如何正确锻炼及一些错误的观念．比如，散步是最好的也是容易做的锻炼，流汗只是身体里水份的流失等．

解答 61．how 考查特殊疑问词+动词不定式． exercise是不及物动词，"特殊疑问词+动词不定式"作about的介词宾语．
62．may/can/will 考查情态动词．情态动词may/can/will表示可能性．
63．that 考查连词．表语从句exercise burns fat from all over the body是完整的，要用连接词that．
64．needs 考查主谓一致．主语To regain it是动词不定式短语，作主语时谓语动词用单数形式．
65．exercising 考查现在分词．在时间状语从句中，当从句的主语与主句的主语相同时，且含有be动词时，可将从句中的主语和be动词一起省略．when exercising相当于when you are exercising．
66．but 考查固定搭配．nothing but意为"只有，只不过"，是固定搭配．
67．It 考查代词．it指代上文中的walking．
68．on 考查介词．have an effect on意为"对…有影响；对…起作用"，是固定搭配．
69．a/per 考查冠词．此处的不定冠词a意为"每一"，与per同义．
70．after 考查连词．根据句意：如果你在锻炼后在几分钟内呼吸不能回到正常，你就锻炼过度了．用连词if．
