During sleep, the fatigue (疲劳) of the body disappears and recuperation ( 恢复) begins. The tired mind gathers new energy. Once awake, the memory improves, and annoyance and problems are seen in a better perspective.Some adults require little sleep; others need eight to ten hours in every twenty-four. Infants sleep sixteen to eighteen hours daily and, as they grow older, the amount gradually diminishes. Young students may need twelve hours; university students may need ten. A worker with a physically demanding job may also need ten, whereas an executive worker under great pressure may manage on six to eight. Many famous people are reputed to have required little sleep. Napoleon, Thomas Edison and Charles Darwin apparently averaged only four to six hours a night.Whatever your individual need, you can be sure that by the age of thirty you will have slept for a total of more than twelve years. By that age you will also have developed a sleep routine: a favorite hour, a favorite bed, a favorite position, and a formula you need to follow in order to rest comfortably. Investigators have tried to find out how long a person can go without sleep. Several people have reached more than 115 hours ?nearly five days, whereas animals kept awake for from five to eight days have died of exhaustion. The limit for human beings is probably about a week.1、The writer implies that _________A、sleep is important for good mental and physical healthB、a light sleep is as restful as a deep sleepC、memory is improved during sleepD、sleep is relatively unimportant for human beings2、From the amount of sleep Napoleon, Edison and Darwin required, we can infer that_______.A、they were famous great menB、 they were executive workersC、 they were intelligent peopleD、 they were involved in mentally demanding work3、The amount of sleep required ________.A、varies greatly from individual to individualB、 depends on an individual''s ageC、 relates to an individual''s occupationD、 all of the above.4、According to the passage, the sleeping routine will be built at the age of _________.A、10B、20C、30D、405、From animal experiments, we can conclude that the final result of the lack of sleep is probably _________A、mental illnessB、mental breakdownC、susceptibility to illnessD、death

共用题干第二篇Sleep DeficitJudging from recent surveys,most experts in sleep behavior agree that there is virtually an epidemic(流 行病)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 (睡眠不足)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 scien- tists 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 up 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,eight 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 programme.In our society,you're considered dynamic if you say you only need 5.5hours' sleep.If you'ye 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 psycho- logical and performance tests requiring them,for instance,to add columns of numbers or recall a passage read to them only minutes earlier."We'ye found that if you're in sleep deficit,performance suffers,"says Dr. David."Short-term memory is weakened,as are abilities to make decisions 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 drives and ambition

根据下面资料,回答题 I′ve often wondered how exactly sleep, or lack of it, can have such an awful effect on our bodies and, guess what, how much we sleep switches good genes on and bad genes off. In the first half of 2013, the Sleep Research Centre at the University of Surrey found a direct link between hours spent sleeping and genes. Every cell in our bodies carries genetic instructions in our DNA that act as a kind of operating handbook. However, each cell only "reads" the part of this handbook it needs at any given moment. Can sleep affect how a gene reads instructions It′s a question asked by Professor Derk-Jan Dijk at the University of Surrey. He set up an experiment and asked his volunteers to spend a week sleeping around seven and a half hours to eight hours a night and the next sleeping six and a half to seven hours. Blood samples were taken each week to compare which genes in blood cells were being used during the long and short nights. The results were rather surprising. Several hundred genes changed in the amount they were being used, including some that are linked to heart disease, cancer, and Type 2 diabetes. Genes to do with cell repair and replacement were used much less. Sleep restriction (six and a half to seven hours a night) changed 380 genes. Of these,220 genes were down regulated (their power was reduced), while 160 were up regulated (their power was increased). Those affected included body-clock genes which are linked to diabetes. One of the most downgraded genes is that which has a role in controlling insulin and is linked to diabetes and insomnia. The most upgraded gene is linked to heart disease. So changing sleep by tiny amounts can upgrade or downgrade genes that can influence our health and the diseases we suffer from when we sleep too little. The important message is that getting close to eight hours of sleep a night can make a dramatic difference to our health in just a few days through the way it looks after our genes. Which of the following can be inferred from the findings of the sleep research 查看材料A.When there is a sleep restriction, genes to do with cell repair and replacement function less.B.In a sleep, several hundred genes change in the amount. The more changes, the worse results.C.When genes are up regulated, they do good to health; when genes arc down regulated, they do harm to health.D.Eight hours of sleep a day can be beneficial to our health in that it looks after our genes.

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.To get a good night's rest,people may not need to______.A: fall asleep againB: become more energetic the following dayC: sleep less than 7 hoursD: confirm those serious consequencesE: suffer sleep problemsF: sleen more than 8 houlrs

共用题干More Than 8 Hours Sleep Too Much of a Good ThingAlthough 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.Paragraph 6______A:Keprike's Research ToolB:Dangers of Habitual Shortages of Sleep C:Criticism on Kripke's ReportD:A Way of Overcoming InsomniaE:Sleep Problems of Long and Short Sleepers F: Classification of Sleep Problems
