More Than 8 Hours Sleep Too Much of a Good Thing
1 .Although the dangers of too little sleep are widely known,new research suggests that people who sleep too much may also suffer the consequences.
2 .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.
3 .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.
4 .Previous studies have shown the potential dangers of chronic shortages of sleep一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.
5 .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.
6 .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.

B:Dangers of Habitual Shortages of Sleep
C:Criticism on Kripke's Report
D:A way of Overcoming Insomnia

参考答案和解析

答案：A

解析：

该段中只包含两个句子，而每个句子中提到了have trouble falling asleep“很难入睡”，这表明该段主题应与睡眠问题相关。选项E和选项F都直接提到了sleep problems “睡眠问题”，因此推测答案可能来自这两个选项之中。选项E意为“睡眠时间长的人和睡眠时间短的人遇到的睡眠问题”，选项F意为“睡眠问题的分类”。结合段落内容来看，第一句主要提到people who clock up 9 or 10 hours each weeknight“每晚睡9-10个小时的人”，即睡眠时间长的人的情况，段落第二句主要提到People who slept only 7 hours each night“每晚只睡 7个小时的人”，即睡眠时间短的人的情况，因此E是答案。
整个段落只包含一个句子，该句主要提到了以前的研究发现揭示了慢性睡眠不足的潜在危险。这与选项B“习惯性睡眠不足的危险”呼应一致，因此答案为B。
对于该段主题的判断具有一定的迷惑性，A和F容易相互成为干扰项，但由于段落中提到的“睡眠问题”是属于问卷上要回答的内容，是和Kripke的直接研究有关，所以判断“Kripke的研究”是段落的主题，因此A是答案。
剩下的三个选项中，选项F作为第1小题的干扰项成为该小题答案的可能性很小，选项C意为“对Kripke报告的批评”，整个段落主要提到了Kripke的研究发现和他的看法：Kripke found...(Kripke发现）；Kripke noted...(Kripke指出……）；he added...（他补充说……），根本没有涉及到对Kripke的批评，因此C是干扰项，答案应该为D。该段首先分析了睡眠时间长的人出现睡眠问题的原因，然后指出减少失眠（睡眠问题的具体表现）的一种方法。
利用题干中的名词短语a good night's rest和名词people作为定位线索，在文章中找到相关句These findings, which DL Daniel Kripke reported in the journal Psycho-somatic 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.依据该句可直接判断F“睡眠超过8小时”是答案。
利用题干中的名词短语long sleepers作为定位线索，同时关注题干中的其他用词，这样在文章中找到相关句Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight（与long sleepers呼应）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。依据该句可直接判断E“出现睡眠问题”是答案。
利用题干中的名词短语one of the sleep problems, the middle of the night 作为定位线索，在文章中找到相关句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.fall asleep again“再次入睡”是fall back to sleep的近义结构，因此答案为A。
利用题干中的名词结构one survey, higher risk of dying作为定位线索，在文章中找到相关句 one report（与survey呼应）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，依据该句可直接判断C“睡眠不足7个小时”是答案。
