问题补充：
Are you sometimes a little tired in the early afternoon? 【小题1】. They may think it’s because we eat too much. Or, in summer, they may think it is too hot. 【小题2】 . About eight hours after you wake up, your body temperature goes down.
In many parts of the world, people take naps(打盹) in the middle of the day. This is really true when it’s warmer, and the hot weather makes work difficult in the early afternoon. Now researchers are saying that naps are good for everyone at any time. 【小题3】If people often take naps, there are often few problems with their hearts.
【小题4】Though doctors may ask them to take naps, however, bosses don’t let them do it! If you do have the chance, remember that the best time to take a nap is about eight hours after you get up. A short sleep too late in the day may only make you feel more tired and sleepy. This can also happen if you sleep for too long. 【小题5】, try a short nap – even ten minutes of sleep can be helpful.
方框所给的选项中选出能填入空白处的最佳选项，补全短文。其中一项为多余选项。（10分）C
答案：
(答案→)C
解析：这篇短文中作者主要介绍了午间小睡的重要性，也是人们最容易忽视的问题，即使没有充足的时间，一二十分钟的小睡也是很有帮助的。
【小题1】开头一句Are you sometimes a little tired in the early afternoon?提出问题，第三句是部分人推测的原因，所以C项属于承上启下的一句；故选C。
【小题2】前面两句是人们推测的两种原因，后面介绍的是体温的变化，所以在此通过however引出真正的原因是什么；故选E。
【小题3】前面提到Now researchers are saying that naps are good for everyone at any time.后面又说如果人们经常小睡，那么心脏的问题会相应减少；由此可知D项We can take naps everywhere.符合前后相衔接的句子；故选D。
【小题4】后面的一句Though doctors may ask them to take naps, however, bosses don’t let them do it! 点明了问题的核心所在，许多人没有时间及机会小睡，所以FBut many working people have no time to take naps.引出问题；故选F。
【小题5】最后的句子try a short nap – even ten minutes of sleep can be helpful.是有条件的策略，即B项If you do not have enough time,如果没有充足的时间，那么休息十多分钟也是很有帮助的；故选Ｂ。
