Answer 1

分析 本文主要講述如何正確鍛煉及一些錯誤的觀念．比如，散步是最好的也是容易做的鍛煉，流汗只是身體里水份的流失等．

解答 61．how 考查特殊疑問詞+動詞不定式． exercise是不及物動詞，"特殊疑問詞+動詞不定式"作about的介詞賓語．
62．may/can/will 考查情態(tài)動詞．情態(tài)動詞may/can/will表示可能性．
63．that 考查連詞．表語從句exercise burns fat from all over the body是完整的，要用連接詞that．
64．needs 考查主謂一致．主語To regain it是動詞不定式短語，作主語時謂語動詞用單數(shù)形式．
65．exercising 考查現(xiàn)在分詞．在時間狀語從句中，當(dāng)從句的主語與主句的主語相同時，且含有be動詞時，可將從句中的主語和be動詞一起省略．when exercising相當(dāng)于when you are exercising．
66．but 考查固定搭配．nothing but意為"只有，只不過"，是固定搭配．
67．It 考查代詞．it指代上文中的walking．
68．on 考查介詞．have an effect on意為"對…有影響；對…起作用"，是固定搭配．
69．a(chǎn)/per 考查冠詞．此處的不定冠詞a意為"每一"，與per同義．
70．a(chǎn)fter 考查連詞．根據(jù)句意：如果你在鍛煉后在幾分鐘內(nèi)呼吸不能回到正常，你就鍛煉過度了．用連詞if．

點評 在一篇200詞左右的語篇（短文或?qū)υ挘┲辛舫?0處空白，部分空白的后面給出單詞的基本形式，要求考生根據(jù)上下文填寫空白處所需的內(nèi)容或所提供單詞的正確形式，所填寫詞語不得多于3個單詞．要做好語法填空題，理解短文是解題的前提，扎實的詞匯、句型和語法知識是基礎(chǔ)，英語國家的背景知識是必要的補(bǔ)充．考生須靈活運(yùn)用語法知識，如單詞詞性、單詞時態(tài)、名詞單復(fù)數(shù)、連接詞、代詞、冠詞等判斷各空白處應(yīng)填寫的內(nèi)容．答完后，還要通讀全文，核對所填單詞形式是否正確，是否符合語境．
