3、s 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 stayingasleep ，a

4、s well as a number of other sleep problems， than people who sleep 8 hours a night.People who slept only 7hours each night also said they had more trouble fallingasleep and feeling refreshed after a nights sleep than 8- hour sleepers.These findings, which DL Daniel Kripke reported in the journal Psyc

5、hosomatic Medicine, demonstrate that people whowant to get a good nights rest may not need to set aside。more than 8 hours a night.He addedthat “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

6、 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.F

7、or 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 whetherthey experienced any sleep problems.Sleep problems included waking in the middle of the night，arising early in the morning and

8、 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

9、 may struggle to get rest at nightsimply because they spend too much time in bed.As evidence，he added that one way to help insomnia is to spend less timein bed.“It stands to reason that if a person spends too longa time in bed, then theyll spend a higher percentage of time awake. ” he said.23.

The center, which will start out with about US$1

13、4million,will help the country develop its chip industry without always depending on imported technology.The center will make use of its research skills and facilities to develop new technology for domestic chip plants. The advent of the center will possibly free the country from the situation that

14、it is always buying almost-outdatedtechnologies from other countries, said the countrysflagship chipmaker. Currently, chip plants in this countryare in a passive situation because many foreign governments don t allow them to import the most advanced technologies, fearing they will be used for milita

15、ry purposes. Moreover,the high licensing fees they have to pay to technology provider are also an important reason for their decision of self-reliance.As mainstream chip production technology shifts from one generation to the next every three to five years, plants with new technology can make more p

16、owerful chips at lower costs, while plants with out-dated equipment, which often costbillions of dollars to build, will be marginalized by the maker.More than 10 chip plants are being built, each costing millions of U.S. dollars. the majority of that money goes to overseas equipment vendors and tech

17、nology owners mainly from Japan and Singapore.Should the new center play a major role in improving the situation in industry, the country admits the US$14million in vestment is still rather small. This country is developing comprehensive technologies. Most of the investment will be spent on setting

22、 the study also found that when 1ess-educated people did suffer stress it was more severe and had a larger impact on their health.From this, researchers have concluded that the day-to-day factors that cause stress are not random.r11ere you are in society determines the kinds of problems that you hav

23、e eachday, and how well you will cope with them.The research team interviewed a national sample of 1.03 1 adults daily for eight days about their stress level and health.People without a high school diploma reported stresson 30 percent of the study days， people with a high schooldegree reported stre

24、ss 38 percent of the time，and people with college degrees reported stress 44 percent of the time.Less advantaged people are less healthy on a daily basis and are more likely to have downward turns in theirhealth 。” lead researcher Dr.Joseph Grzywacz， of WakeForest University Baptist Medical Center,

25、said in a prepared statement.“The downward turns in health were connected with daily stressors.and the effect of daily stressors on theirhealth is much more devastating for the less advantaged.”Grzywacz suggested follow-up research to determine why less-educated people report fewer days of stress wh

26、en it is known their stress is more acute and chronic.“If something happens every day, maybe itsnot seen as a stressor”Grzywacz says. “Maybe it is just 1ife.”词汇：stressful adj.紧张的; 压力重的diploma n.毕业文凭，毕业证书stressor n.紧张刺激物devastating adj.毁灭性的follow-up n.(对病人的 ) 随访31.
