共用题干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 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.Paragraph 6______A: Kripke's ResearchB: Dangers of Habitual Shortages of SleepC: Criticism on Kripke's ReportD: A way of Overcoming InsomniaE: Sleep Problems of Long and Short SleepersF: Classification of Sleep Problems
共用题干第二篇Sleep Necessary for MemoriesBurning the midnight oil before an exam or interview does harm to the performance according to a recent research which found that sleep is necessary for memories to be taken back into the brain.A good night's sleep within 30 hours of trying to remember a new task is a required condition of having good recall in the weeks ahead,scientists have found.The research,published in the December issue of Nature Neuroscience,showed that it was the act of sleep,rather than the simple passage of time,that was critical for long-term memory formation."We think that getting that first night's sleep starts the process of memory consolidation （巩固）,"said Robert Stickgold , a sleep researcher at Harvard Medical School who conducted the latest study."It seems that memories normally wash out of the brain unless some process nails them down.My suspicion is that sleep is one of those things that does the nailing down," Professor Stickgold said.With about one in five people claiming that they are so chronically short of sleep that it affects their daily activities,the latest work emphasizes the less well-understood side effect-serious memory impairment（损害）.Volunteers in an experiment found it easier to remember a memory task if they were allowed to sleep that night.But for those kept awake,no amount of subsequent sleep made up for the initial loss.Professor Stickgold's team trained 24 people to identify the direction of three diagonal （斜线形的）bars flashed for a sixtieth of a second on a computer screen full of horizontal （水平的）stripes.Half of the subjects were kept awake that night,while the others slept.Both groups were allowed to sleep for the second and third nights to make up for any differences in tiredness between the volunteers.Those who slept the first night were significantly and consistently better at remembering the task while the second group showed no improvement despite enjoying two nights of catch-up sleep. In Stickgold's experiment,those who were kept awake on the first nightA:could very well remember the direction of the diagonal bars.B:didn't do any better after two nights' sleep.C:were as tired as those who were not.D:could recall the direction of more bars than those who were not.

共用题干第三篇Judging from recent surveys,most experts in sleep behavior agree that it is virtually an epidemic of sleepiness in the nation."I can't think of a single study that hasn't found Americans getting less sleep than they ought to,"says Dr. David.Even people who think they are sleeping enough would probably be better off with more rest.The beginning of our sleep-deficit crisis can be traced to the invention of the light bulb a century ago.From diary entries and other personal accounts from the 18th and 19th centuries,sleep scientists have reached the conclusion that the average person used to sleep about 9.5 hours a night. "The best sleep habits once were forced on us,when we had nothing to do in the evening down on the farm,and it was dark." By the 1950s and 1960s,that sleep schedule had been reduced dramatically,to between 7.5 and 8 hours,and most people had to wake to an alarm clock."People cheat on their sleep,and they don't even realize they're doing it,"says Dr. David."They think they're okay because they can get by on 6.5 hours,when they really need 7.5,8 or even more to feel ideally vigorous.""Perhaps the most merciless robber of sleep,"researchers say,"is the complexity of the day." Whenever pressures from work,family,friends and community mount,many people consider sleep the least expensive item on his program."In our society,you're considered dynamic if you say you only need 5.5 hours' sleep.If you've got to get 8.5 hours,people think you lack drive and ambition."To determine the consequences of sleep deficit,researchers have put subjects through a set of psychological and performance tests requiring them,for instance,to add columns of numbers or recall a page read to them only minutes earlier."We've found that if you're in sleep deficit,performance suffers,"says Dr. David."Short-term memory is weakened,as are abilities to make decision and to concentrate."Many Americans believe that__________.A:sleep is the first thing that can be sacrificed when one is busyB:they need more sleep to cope with the complexities of everyday lifeC:to sleep is something one can do at any time of the dayD:enough sleep promotes people's drive and ambition

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.Long sleepers are reported to be more likely to______.A:fall asleep againB:become more energetic the following dayC:sleep less than 7 hoursD:confirm those serious consequencesE:suffer sleep problemsF: sleep more than 8 hours
问答题Practice 1 Are you a real grump (脾气坏的人) in the mornings? Do you wake up every day feeling tired, angry and upset, and all too ready to flit the snooze (瞌睡) button? If so, then a new alarm clock could be just for you. The clock, called SleepSmart, measures your sleep cycle, and waits for you to be in your lightest phase of sleep before waking you up, Its makers say that should ensure you wake up feeling refreshed (恢复精力) every morning. As you sleep you pass through a sequence of sleep states—light sleep, deep sleep and REM sleep (快速眼动睡眼)—that repeats approximately every 90 minutes. The points in that cycle at which you wake can affect how you feel later, and may even have a greater impact than how long or little you have slept. Being wakened during a light phase means you are more likely to wake up cheerful and full of life and interest. SleepSmart records the distinct pattern of brain waves produced during each phase of sleep, via a headband equipped with electrodes (电极) and a microprocessor. This measures electric activity of the wearer’s brain, and communicates wirelessly with a clock unit near the bed. You program the clock with the latest time at which you want to be wakened, and it then at the proper time wakes you during the last light sleep phase before that. The concept was invented by a group of students at Brown University in Rhode Island after a friend complained of waking up tired and performing poorly on a test. “As sleep-deprived (剥夺) people ourselves, we started thinking of what to do about it,” says Eric Shashoua, a recent college graduate and now chief executive officer of Axon Sleep Research Laboratories, a company created by the students to develop their idea. They have almost finished a prototype and plan to market the product by next year.
