綜合類：概括大意More Than 8 Hours Sleep
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 nights 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 nights rest may not need to set aside.more than 8 hours a night.He added that“it might be a good ideafor 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.
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.
KriDke 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 theyll spend a higher percentage of time awake.”he said.

解析：
1. E： Investigators ……found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling， than……該句回應了文章的主題—睡眠時間太長不是好事；對應被選項發現只有E和F與這個內容有關系，但段落最后一句中又提到了睡眠不足的人的問題，因此判斷E是答案（睡眠長和睡眠短的人所面臨的睡眠問題）。
2.B.分析：段落的結構—— Previous studies have shown the potential dangers of chronic shortages of sleep一for instance……表明了該段的中心是講述“長期睡眠不足的潛在危險”。
3. A. 分析：對于該段落答案的選擇具有一定的迷惑性，A和F容易相互成為干擾項，但由于段落中提到的“睡眠問題”是屬于問卷上要回答的內容，是和Keprike的直接研究有關，所以判斷A是答案。同時猜測F可能是出題者設置的干擾項。
4. D： 段落中出現的Kripke found， Kripke noted和he added表明“Kripke的觀點和態度應該是該段的中心”，對比被選項排除C（段落中沒有出現批評的話語）和F（段落中沒有具體提到睡眠問題的表現形式），而段落最后第2句提到了克服失眠的方法—少花時間在床上，與D呼應。
