1、第三部分 概括大意與完成句子第一篇 More Than 8 Hours Sleep Too Much of a Good Thing1 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 Sandiego found that people who clock

3、ep than 8-hour sleepers.23 These findings, which Dr.Daniel Kripke reported in the journal Psychosomatic Medicine3, demonstrate that people who want to get a good nights rest may not need to set aside4 more than 8 hours a night. He added that “it might be a good idea” for people who sleep more than 8
