2013年6月英语四级答案(大家版卷一)

　　Whether you think you need daytime rest or not, picking up a nap habit—or continuing to make time for one—is a smart, healthy move. Consider the evidence: The Mayo Clinic says naps promote relaxation, reduced fatigue, better mood and alertness, and a sharper-working mind. A 2008 British study found that compared to getting more nighttime sleep or guzzling caffeine, a mid-day nap was the best way to cope with the mid-afternoon slump.

　　According to the Harvard Health Letter, several studies have shown that people remember new information better when they take a nap shortly after learning it. And, most incredibly, a 2007 study of nearly 24,000 Greek adults in the Archives of Internal Medicine found that people who napped regularly had a 37 percent reduced risk of dying from heart disease compared to people who didn’t nap.

　　Of course, napping isn’t right for everyone. If you’re prone to insomnia, naps that are too long or taken too late in the day can interfere with your ability to fall or stay asleep at night. Also, people with certain sleep disorders, like sleep apnea or narcolepsy, may feel more tired if they take a nap than if they don’t.

　　But for most, naps can make you feel sharper and happier. Naps provide different benefits depending on how long they are, says MentalFloss.com. A 20-minute nap will boost alertness and concentration; a 90-minute snooze can enhance creativity.

　　According to Prevention.com, you experience a natural dip in body temperature between 1 p.m. and 3 p.m. A power nap at this time can boost alertness for several hours and, for most people, shouldn’t affect being able to fall asleep at night.

　　Pick a dark, cozy place that’s not too warm or too chilly. Prevention.com recommends napping on the couch instead of in bed, so you’re less tempted to snooze for too long.

　　Surprisingly, the best place to crash may be a hammock if you have one. A Swiss study published last year found that people fell asleep faster and had deeper sleep when they napped in a hammock than in a bed. That same rocking motion that lulls babies to sleep works wonders for grown-ups too.

　　点评：本篇完形填空摘自Read’s Digest， 再次体现了四六级考试频繁使用外刊素材的特点。

　　本篇文章主要讲述了睡午觉的好处。不管你是否觉得有睡午觉的必要，养成这样的习惯可以让你有效对抗下午的困顿。但是，睡午觉也未必适合每个人。如果你本身已经有失眠的问题，睡午觉会让你晚上更难入睡。

　　除了通过上下文理解才能得出答案的题目之外，仍然考察了一些语法点。比如第69题，A 2008 British study found that compared to getting more nighttime sleep, a mid-day nap was the best way to cope __69___ the mid-afternoon sleepiness. 这里明显考察的就是词组cope with.表示处理、应对。

　　再比如第73题，And most incredibly, a 2007 study of nearly 24,000 Greek adults in the Archives of Internal Medicine found that people who napped regularly had a 37% reduced risk of dying __73__ heart disease ……这里也非常明显的考察了词组die from

　　同时也考察了对动词词义的辨析。例如第77题，A 20-minute nap will boost alertness and concentration; a 90-minute snooze will __77___creativity.

　　选项包括了enlarge, engage, enhance 和enlighten. 根据前半句话的含义可知，20分钟午睡可以提高专注度，那么90分钟的午睡就更应该对创造力有益了。通过对4个选项的分析，只有enhance能够表达这个意思。此处除了要搞清楚4个选项本身的含义外，还要注意运用上下文来进行最终判断。

　　总体来说，整篇文章难度并不大，也没有出现过于生僻的表述方式。只要能够清楚辨析选项，熟悉搭配，并且充分理解上下文，就能够顺利完成本篇完形填空。
