　　Taking a Nap During the Day

　　Medical experts say most Americans do not get 51 sleep. They say more Americans need to rest for a short period in the middle of the day. They are advising people to sleep lightly before 52 with other activities.

　　One study earlier this year found that persons who sleep for a few minutes during the day were less 53to die of heart disease. The study followed more than 2,300 Greek adults 54 about six years. Adults who rested for half an hour 55 three times a week had a 37 present lower risk of dying from heart disease than those who did not nap.

　　Study organizers said the strongest evidence was in working men. They said naps might improve 56 by mitigating tension caused by work.

　　Some European and Latin American businesses have supported the 57 of napping for many years. They urge people to 58 work, go home and have a nap before returning. In the United States, some companies let workers rest briefly in their offices. They believe this reduces 59 and accidents, and 60 increases the amount of work a person can do.

　　Sleep experts say it is likely that people make more mistakes at work than at other times. They say people should not carry out important duties when they feel 61 And they say the best thing to do is to take a nap. About twenty minutes of rest is 62 you need. Experts say this provides extra energy and can increase your effectiveness 63 the end of the day. But experts warn that a nap 64 last no more than twenty to thirty minutes. A longer nap will put the body into deep sleep and waking up will be 65

　　答案与解析

　　51　D本段第二句说“more Americans need to rest for a short period in the middle of the day”，引导我们选择(not)enough。因为睡眠不够，才要中午“打个盹”。选项A：文不对题。选项B：bad(sleep)与上下文不符，因为通篇文章没有提到过，中午打盹的原因上晚上没有睡好。选项C：明显不合乎逻辑。“由于没有睡不好(即：晚上睡好了)，白天还要补睡一会儿”，于理说不通。所以，惟一合理的选择是D。

　　52　C空格52所在句子的意思是：医学专家建议人们在进行其它活动之前，最好小睡一会。四个选项中，只有continuing(选项C)最接近上述的理解。

　　53　B空格53所在的句子说的是“心脏病致死”的问题，lovely，fondly和finely分别表达“可爱”、“喜欢”和“美好”的意思，明显不对。less likely是“可能性较低一些”的意思，选择likely符合上下文的意思。本段最后一句说，成年人白天打盹半小时，一周三次，其心脏病致死的概率比不打盹的人要低37%。这更证实了选likely是正确的。

　　54　A本句的意思是，调查进行了六年。about six years之前要用表达一段时间的介词for。介词at和with明显与about six years不搭配，而选项in(about six years)表达的是未来的时间，如：He will come to Beijing in one day or tw0.(他一、两天之内会到北京。)

　　55　A at first和at last明显与本句的意思不符。若选at most(最多)，本句的意思成了“成年人白天打盹半小时，一周不得超过三次，其心及脏病致死的概率比不打盹的人要低37%”，意思有点令人费解。改说成，“一周至少三次”才说得通。所以at least是答案。

　　56　B篇文章在阐述白天打盹有益于健康，选项B是答案。

　　57　C空格57所在的句子的意思是：多年来，欧洲和拉丁美洲的一些公司支持白天打盹的?(空格中填哪一个词?)。很明显，空格中填入experiment(试验)或reform(改革)则离题太远，而way(方式)肯定没有idea(想法)好。C是答案。

　　58　D从上下文判断，空格58的词应该与“中止(work)”有关。四个选项中，只有leave合乎这一条件。而其它三个选项repeat(重复)、improve(改进)和change(改变)与后半旬的go home and have a nap搭不上。

　　59　B前面一句说，美国有些公司让职员在办公室打个盹，这样可以减少些事故等。填入空格59的词应该与accidents(事故)一样，是一个负面意思的词。mistakes(选项B)符合这个条件，是答案。reduce work/energy time都不合理。

　　60　D打个盹有两个好处：1)可以减少错误和事故;2)可以增加工作效率。从上下文判断，选also。too从词义上说也可以，但用法上有问题，因为“…this…too increases the amount…”把too置于动词increases之前很少见。never和seldom的意思与上下文不匹配。

　　61　C前半句说，“people should not carry out important duties…”，后半句自然会想到“when they feel sleepy”。而when they feel ready good happy都说不通。

　　62　A本句的意思是：大约20分钟的打盹是你所需要的。所以，About twenty minutes of rest is few/any/nothing you need与上述意思不符，只有until(the end of the day)才说得通。

　　63　C前半句说，“(指打盹)”后面接不搭配，只有C才是答案。

　　64　D本句的意思是：专家警告说：打盹不能(或不应该)超过30分钟。这题选should最合适。

　　65　B本句表达的意思应该是上一句“A longer nap will put the body into deep sleep”引出的结果。打盹时间长了，就会进入深睡状态，很难醒过来。选difficult是合适的，其它三个选项的意思脱离了上下文，不会是答案。
