【解析】

本文是一篇说明文。文章介绍了几项定期锻炼的好处，这是坚持锻炼的新理由。

【1】上文提示“这是一个残酷的现实，锻炼并不是减肥和保持体重的可靠方法。”下文提示“下面是定期锻炼的好处。”承接上下文，F项But that doesn’t mean you should give up the effort.（但这并不意味着你应该放弃努力。）切题。该项和上句是一种转折关系，由but连接；下文解释“为什么不应该放弃努力”，与该项衔接紧密。故选F。

【2】此空是小标题。根据下面的小标题，可知应该在A/B中选。再根据本段第一句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.（一项新的研究发现，仅仅一小段时间的锻炼可以帮助提高在接下来的几个小时里记住事情的能力。）由此推知，A项It improves memory.（它提高记忆）符合本段内容。故选A。

【3】根据本段小标题It may keep off depression.（它可以防止抑郁。），再根据空格下文提示Researchers found that women who exercised regularly reported about 50% fewer depressive signs than women who didn’t exercise as much.（研究人员发现，经常锻炼的女性比不运动的女性少了50%的抑郁症状。）承接标题和下文，E项Working out regularly might prevent depression.（经常锻炼可以预防抑郁症。）符合上下文语境。故选E。此处关键词depression。

【4】根据本段小标题It can control appetite(食欲). （它控制食欲。），再根据下文提示“我不需要用食物填饱肚子。”承接下文，C项Here is the energy source I need.（这是我需要的能量来源。）符合上下文语境。故选C。

【5】根据本段小标题It increases energy.（它增加能量。），再根据空格上文提示“在最近的一份报告中，骑自行车20分钟的男性自我报告的能量水平增加了166%，而他们坐着的时候增加了15%，并且在同样的时间内没有做任何事情。”承接上文，G项If you need a reason to work out, energy increase is a worthwhile one.（如果你需要一个理由去锻炼，那么能量的增加是值得的。）切题。故选G。

在做七选五时一定要注意and/but/so/besides/however/furthermore/moreover/in addition/what’s more等词汇、固定结构的运用。它们连接了上下文，起着承上起下的作用。像but（但是）、however（然而），表示转折，这说明前后的内容相反或相对。把握住这一点，做起题来就会得心应手。本题第1小题，上文提示“这是一个残酷的现实，锻炼并不是减肥和保持体重的可靠方法。”而后文也就是这篇文章主要讲述的是“定期锻炼的好处”，所以与上文that所指内容构成相反，故这是一种转折关系。而F项But that doesn’t mean you should give up the effort.（但这并不意味着你应该放弃努力。）由but连接，前后是一种转折关系。此处that指的就是“锻炼并不是减肥和保持体重的可靠方法”。
