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.

[单项选择]Passage Four
Unless you have visited the southern United States, you probably have never heard of kudzu. Kudzu, as any southern farmer will sadly tell you, is a super-powered weed. It is a strong climbing vine. Once it gets started, kudzu is almost impossible to stop. It climbs to the tops of the tallest trees. It can cover large buildings. Whole barns and farm houses have been known to disappear from view. It has even been said to engulf small, slow-moving children, but that is probably an exaggeration. Still, wherever it grows, its thick, twisting vines are hard to remove.
Kudzu was once thought to be a helpful plant. Originally found in Asia, it was brought to America to help fight erosion. It was planted where its tough roots, which grow up to five feet long, could help hold back the soil. But the plant soon spread to places where it wasn’t wanted. Farmers now have to fight to keep it from eating up all the nutrients in the soil and killing other plants.
A. erosion becomes a problem
B. farmers attack the kudzu
C. employment is bound to improve
D. kudzu soon grows over them
