【解析】
【分析】
本文是說明文。介紹了體育鍛煉的種種好處，建議學生們積極參加鍛鍊。
86．考查形容詞。surprised用來修飾人；surprising用來修飾物，這裏修飾指物的benefits指“令人吃驚的好處”，故應該把surprised改爲surprising。
87．考查冠詞。way是可數名詞單數，an important way一種重要的方式，故important前加an。
88．考查連詞。句意：它不僅可以幫助你實現有益的減肥，而且每次你鍛鍊，它還有助於更有效地降低患病風險。此處是固定句型：not (also)...不僅……而且……。故and改爲but。
89．考查副詞。此處應用副詞修飾現在分詞exercising，故regular改爲regularly。
90．考查主謂一致。本句是定語從句，which是關係代詞，代指前面一句話的內容，故謂語動詞應用單數，故把have改爲has。
91．考查代詞。句意：它也教會你如何與他人共事。故us改爲you。
92．考查動詞的時態。用於情態動詞can後，和answer , think並列，故developed改爲develop。
93．考查非謂語動詞。此處爲動名詞做主語，動詞原形不能做主語，故Have改爲Having。
94．考查句子結構。句意：有一個健康的大腦很有用。後面沒有賓語，此處for多餘，故for去掉。
95．考查名詞的複數形式。take exercise進行鍛鍊，exercise意爲“鍛鍊”時是不可數名詞，故exercises改爲exercise。
