【解析】

本文是一篇說明文。文章介紹了幾項定期鍛煉的好處，這是堅持鍛煉的新理由。

【1】上文提示“這是一個殘酷的現(xiàn)實，鍛煉并不是減肥和保持體重的可靠方法。”下文提示“下面是定期鍛煉的好處。”承接上下文，F項But that doesn’t mean you should give up the effort.（但這并不意味著你應(yīng)該放棄努力。）切題。該項和上句是一種轉(zhuǎn)折關(guān)系，由but連接；下文解釋“為什么不應(yīng)該放棄努力”，與該項銜接緊密。故選F。

【2】此空是小標(biāo)題。根據(jù)下面的小標(biāo)題，可知應(yīng)該在A/B中選。再根據(jù)本段第一句A new study had found that just a short period of exercise can help improve the ability to remember things in the hours that follow.（一項新的研究發(fā)現(xiàn)，僅僅一小段時間的鍛煉可以幫助提高在接下來的幾個小時里記住事情的能力。）由此推知，A項It improves memory.（它提高記憶）符合本段內(nèi)容。故選A。

【3】根據(jù)本段小標(biāo)題It may keep off depression.（它可以防止抑郁。），再根據(jù)空格下文提示Researchers found that women who exercised regularly reported about 50% fewer depressive signs than women who didn’t exercise as much.（研究人員發(fā)現(xiàn)，經(jīng)常鍛煉的女性比不運動的女性少了50%的抑郁癥狀。）承接標(biāo)題和下文，E項Working out regularly might prevent depression.（經(jīng)常鍛煉可以預(yù)防抑郁癥。）符合上下文語境。故選E。此處關(guān)鍵詞depression。

【4】根據(jù)本段小標(biāo)題It can control appetite(食欲). （它控制食欲。），再根據(jù)下文提示“我不需要用食物填飽肚子�！�承接下文，C項Here is the energy source I need.（這是我需要的能量來源。）符合上下文語境。故選C。

【5】根據(jù)本段小標(biāo)題It increases energy.（它增加能量。），再根據(jù)空格上文提示“在最近的一份報告中，騎自行車20分鐘的男性自我報告的能量水平增加了166%，而他們坐著的時候增加了15%，并且在同樣的時間內(nèi)沒有做任何事情。”承接上文，G項If you need a reason to work out, energy increase is a worthwhile one.（如果你需要一個理由去鍛煉，那么能量的增加是值得的。）切題。故選G。

在做七選五時一定要注意and/but/so/besides/however/furthermore/moreover/in addition/what’s more等詞匯、固定結(jié)構(gòu)的運用。它們連接了上下文，起著承上起下的作用。像but（但是）、however（然而），表示轉(zhuǎn)折，這說明前后的內(nèi)容相反或相對。把握住這一點，做起題來就會得心應(yīng)手。本題第1小題，上文提示“這是一個殘酷的現(xiàn)實，鍛煉并不是減肥和保持體重的可靠方法。”而后文也就是這篇文章主要講述的是“定期鍛煉的好處”，所以與上文that所指內(nèi)容構(gòu)成相反，故這是一種轉(zhuǎn)折關(guān)系。而F項But that doesn’t mean you should give up the effort.（但這并不意味著你應(yīng)該放棄努力。）由but連接，前后是一種轉(zhuǎn)折關(guān)系。此處that指的就是“鍛煉并不是減肥和保持體重的可靠方法”。
