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 questionaires,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 Kridke found that people who slept between 9 and 10 hours each night were more like-ly 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.

To get a good night's rest,people may not need to______.
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: sleen more than 8 houlrs

答案：F
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。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，段落第一句主要提到people who clock up 9 or 10 hours each weeknight“每晚睡9一10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”呼应，因此E是答案。
整个段落只包含一个句子，该句主要以前的研究揭示了慢性睡眠不足的潜在危险。这与B项“习惯性睡眠不足的危险”呼应一致。所以答案为B。
A和F容易相互成为干扰项，这对于该段主题的判断具有一定的迷惑性，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3个选项中，选项F作为第1小题的干扰项成为本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： Kridke found ... (Kridke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，然后指出克服失眠（睡眠问题的具体表现）的一种方法。
利用题干中的名词短语。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项“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项“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. A项fall asleep again“再次入睡”是fall back to sleep的 近义结构，所以答案为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 peo-ple who sleep more．依据该句可直接判断C项“睡眠不足7个小时”是答案。

第3题：

Which of the following is true according to the passage?

A. People will all become short-sighted after they begin to go to school.

B. Playing outdoors for 2 or 3 hours every day can help protect your eyesight.

C. Children in Australia are more likely to get short-sighted than those in Singapore.

D. If you spend two or three hours playing outside each day, you won’t get short- sighted.

One of the sleep problems is waking in the middle of the night,unable to______.
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：A

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。
