问题共用题干 More Than 8 Hours Sleep Too Much of a Good Thing

Although the dangers of too little sleep are widely known,new research suggests that people who sleep too much may also suffer the consequences.
Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep,as well as a number of other sleep problems,than people who sleep 8 hours a night. People who slept only 7 hours each night also said they had more trouble falling asleep and feeling refreshed after a night's sleep than 8-hour sleepers.
These findings,which DL Daniel Kripke reported in the journal Psychosomatic Medicine, demonstrate that people who want to get a good night's rest may not need to set aside more than 8 hours a night. He added that it might be a good idea for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed,but cautioned that more research is needed to confirm this.
Previous studies have shown the potential dangers of chronic shortages of sleep,for instance, one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more.
For the current report,Kripke reviewed the responses of 1,004 adults to sleep questionnaires,in which participants indicated how much they slept during the week and whether they experienced any sleep problems.Sleep problems included waking in the middle of the night,arising early in the morning and being unable to fall back to sleep,and having fatigue interfere with day-to-day functioning.
Kripke found that people who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours.In an interview,Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evidence,he added that one way to help insomnia is to spend less time in bed."It stands to reason that if a person spends too long a time in bed,then they'll spend a higher percentage of time awake,"he said.

选项 One survey showed that people who habitually______each night have a higher risk of dying. A:fall asleep again B:become more energetic the following day C:sleep less than 7 hours D:confirm those serious consequences E:suffer sleep problems F: sleep more than 8 hours

答案 C

解析 Investigators … found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling , than…该句回应了文章的主题―睡眠时间太长不是好事。对应被选项发现只有E和F与这个内容有关系，但段落最后一句中又提到了睡眠不足的人的问题，因此判断E（睡眠时间长和睡眠时间短的人所面临的睡眠问题）是答案。
第四段只有一句话：Previous studies have shown the potential dangers of chronic shortages of sleep , for instance…这句话表明了该段的中心是“长期睡眠不足的潜在危险“。因此选B。
第五段一开始就提到了Kripke的研究，但后来也说到Sleep problems included … A和F容易相互成为干扰项，具有一定的迷惑性。但由于段落中提到的“睡眠问题”属于Kripke的问卷上要回答的内容，和Kripke的研究有关，所以判断A是答案。
第六段中出现的Kripke found , Kripke noted和he added表明Kripke的观点和态度应该是该段的中心，对比被选项，排除C（段落中没有出现批评的话语）和F(段落中没有具体提到睡眠问题的表现形式），而该段倒数第二句中one way to help insomnia is to spend less time in bed(克服失眠的方法之一是少花时间在床上）与D呼应。
根据搭配结构need to do sth．判断所有选项都在语法上合适。因此要借助句意来判断，答案是F。
借助句意“根据报道，睡眠时间长的人更有可能……”，并结合文章主题（睡眠时间长不是好事情）判断E合适。也可借助文章中的相关内容（利用题干中的Long sleepers和 more likely作为答案线索）: Kripke found that people who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours.
句意为“其中的一个睡眠问题是在半夜醒来，不能……”文章第五段倒数第一句话提到午夜醒来很难再次入睡，直接判断A合适。
句意：“一项调查显示那些习惯性每晚……的人有更高的死亡风险。”在第四段找到相关信息：people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more．判断C是答案。
