A good（）of sleep every night is also important your health.

drive to sleep after 15 minutes of inactivity.

In 99 cases out of 100, insomnia(失眠) is caused by a disturbance of the natural sleep rhythm. The reasons why the rhythm has been disturbed are many and they range from drugs that are being taken to treat a separate medical condition to anxiety. A sudden change in lifestyle. or climate could do it, or just that you’ve fallen into the habit of dozing off(打瞌睡) in front of the television.

Certainly the body must have enough sleep. Tests that deprived people of sleep have proved lack of it can cause fairly rapid physical and mental deterioration(恶化). But on the other hand, it doesn’t need too much. So if you’re sleeping in front of the TV, you won’t sleep soundly at night. Similarly, if you’re holidaying in Spain, and spending your days sleeping on the beach, chances are that you’ll be wide awake at bedtime.

Of course, the problem for my summer insomniacs is that, despite an almost overwhelming urge to put their heads down on their desks in the afternoons, they aren’t getting any extra sleep to compensate for their wakeful nights. For the worst sufferers I sometimes prescribe(开药方) a mild sleeping pill which, after a few nights, reestablishes the body’s natural sleep rhythm, conditioning it to accept the heat.

From the passage, insomnia results from ______.

A.the interrupting of the ordinary sleep pattern

B.being unable to sleep

C.keeping awake at night

D.drugs to treat a special disease

Lack of sleep will lead to ______.A.a sudden change in lifestyle

B.a good condition in body

C.the habit of being sleep in front of the television

D.a quick drop in both body and mind condition

The problem for the author’s insomniacs is that they ______.A.can’t make up for the sleepless nights

B.sleep in the afternoon

C.can have extra sleep at night

D.can never sleep well

A mild sleeping pill can help a person well ______.A.spend time sleeping

B.recover their normal sleep

C.keep awake at night

D.compensate for their missing sleep

Council. It has been known for some time that the amount of sleep people get has,【C1】______declined over the years. But【C2】______the average amount of sleep we are getting has fallen, rates of obesity and diabetes have soared. Could the two be connected？ We wanted to see what the【C3】______would be of increasing average sleep by just one hour. So we asked seven volunteers, who【C4】______sleep anywhere between six and nine hours, to be【C5】______at the University of Surreys Sleep Research Centre. The volunteers were randomly【C6】______to two groups. One group was asked to sleep for six-and-a-half hours a night, the other got seven-and-a-half hours. After a week the researchers took blood tests and the volunteers were asked to switch sleep【C7】______. The group that had been sleeping six-and-a-half hours got an【C8】______hour, the other group slept an hour less. Computer tests designed to measure brain wave activity【C9】______that most of them struggled with mental agility tasks when they had less sleep, but the most interesting results came from the blood tests that were【C10】______. Dr Simon Archer and his team at Surrey University were【C11】______interested in looking at the genes that were switched on or off in our volunteers【C12】______changes in the amount that we had made them sleep. "We found that【C13】______there were around 500 genes that were affected," Archer【C14】______. "Some which were going up, and some which were going down." What they discovered is that when the volunteers【C15】______back from seven-and-a-half to six-and-a-half hours sleep a night, genes that are【C16】______with processes like immune response and response to stress became more【C17】______The team also saw increase in the activity of genes related to diabetes and risk of cancer. The【C18】______happened when the volunteers added an hour of sleep. So the clear【C19】______from this experiment was that if you are getting less than seven hours sleep a night and can alter your sleep habits, even one hour more, it could make you【C20】______.

【C1】

A．by chance

B．on average

C．at length

D．for good

Of all the components of a good night’s sleep, dreams seem to be least within our control. In dreams, a window opens into a world where logic is suspended and dead people speak. A century ago, Freud formulated his revolutionary theory that dreams were the disguised shadows of our unconscious desires and fears; by the late 1970s, neurologists had switched to thinking of them as just “mental noise” -- the random byproducts of the neural-repair work that goes on during sleep. Now researchers suspect that dreams are part of the mind’s emotional thermostat, regulating moods while the brain is “off-line.” And one leading authority says that these intensely powerful mental events can be not only harnessed but actually brought under conscious control, to help us sleep and feel better, “It’s your dream,” says Rosalind Cartwright, chair of psychology at Chicago’s Medical Center. “If you don’t like it, change it.”

Evidence from brain imaging supports this view. The brain is as active during REM (rapid eye movement) sleep -- when most vivid dreams occur -- as it is when fully awake, says Dr, Eric Nofzinger at the University of Pittsburgh. But not all parts of the brain are equally involved; the limbic system (the “emotional brain”) is especially active, while the prefrontal cortex (the center of intellect and reasoning) is relatively quiet. “We wake up from dreams happy or depressed, and those feelings can stay with us all day.” says Stanford sleep researcher Dr. William Dement.

The link between dreams and emotions show up among the patients in Cartwright’s clinic. Most people seem to have more bad dreams early in the night, progressing toward happier ones before awakening, suggesting that they are working through negative feelings generated during the day. Because our conscious mind is occupied with daily life we don’t always think about the emotional significance of the day’s events -- until, it appears, we begin to dream.

And this process need not be left to the unconscious. Cartwright believes one can exercise conscious control over recurring bad dreams. As soon as you awaken, identify what is upsetting about the dream. Visualize how you would like it to end instead; the next time is occurs, try to wake up just enough to control its course. With much practice people can learn to, literally, do it in their sleep.

At the end of the day, there’s probably little reason to pay attention to our dreams at all unless they keep us from sleeping or “we waken up in a panic,” Cartwright says. Terrorism, economic uncertainties and general feelings of insecurity have increased people’s anxiety. Those suffering from persistent nightmares should seek help from a therapist. For the rest of us, the brain has its ways of working through bad feelings. Sleep -- or rather dream -- on it and you’ll feel better in the morning.

31. Researchers have come to believe that dreams ________.

[A] can be modified in their courses

[B] are susceptible to emotional changes

[C] reflect our innermost desires and fears

[D] are a random outcome of neural repairs

y found that if people have the ability to work from home and to compress work weeks, they are more likely to make healthier lifestyle. choices, to exercise more and to sleep better.

While the primary driver behind the flexibility movement was to help people, especially women, combine work and family, evidence suggests this is clearly not only a women's issue, Grzywacz, who reported the findings in the Journal of Occupational and Environmental Medicine, said.

The researchers looked at Health Risk Appraisals from employees in jobs ranging from warehouse and production workers to executives at a large multinational pharmaceutical company.

The firm used for the study is consistently recognized by Working Mother magazine as among the most family-friendly employers in the United States.

He said the research shows public health departments and organizations that they could get something out of giving their employees more flexibility.

Sleepy Students Perform. Worse

A Staying up an hour or two past bedtime makes it far harder for kids to learn, say scientists who deprived youngsters of sleep and tested whether their teachers could tell the difference. They could. If parents want their children to thrive academically, "Getting them to sleep on time is as important as getting them to school on time," said psychologist Gahan Fallone, who conducted the research at Brown Medical School.

B The study, unveiled Thursday at an American Medical Association science writers meeting, was conducted on healthy children who had no evidence of sleep--or learning-related disorders. Difficulty paying attention was among the problems the sleepy youngsters faced—raising the question of whether sleep deprivation could prove even worse for people with attention deficit hyperactivity disorder, or ADHD. Fallone now is studying that question, and suspects that sleep problems "could hit children with ADHD as a double whammy."

C Sleep experts have long warned that Americans of all ages don't get enough shuteye. Sleep is important for health, bringing a range of benefits that, as Shakespeare put it, "knits up the raveled sleave of care." Not getting enough is linked to a host of problems, from car crashes as drivers doze off to crippled memory and inhibited creativity. Exactly how much sleep correlates with school performance is hard to prove. So Brown researchers set out to test whether teachers could detect problems with attention and learning when children stayed up late—even if the teachers had no idea how much sleep their students actually got.

D They recruited seventy-four 6- to 12-year-olds from Rhode Island and southern Massachusetts for the three-week study. For one week, the youngsters went to bed and woke up at their usual times. They already were fairly good sleepers, getting nine to 9.5 hours of sleep a night. Another week, they were assigned to spend no fewer than ten hours in bed a night. The other week, they were kept up later than usual: First- and second-graders were in bed no more than eight hours and the older children no more than 6. 5 hours. In addition to parents' reports, the youngsters wore motion-detecting wrist monitors to ensure compliance.

E Teachers weren't told how much the children slept or which week they stayed up late, but rated the students on a variety of performance measures each week. The teachers reported significantly more academic problems during the week of sleep deprivation, the study, which will be published in the journal Sleep in December, concluded. Students who got eight hours of sleep or less a night were more forgetful, had the most trouble learning new lessons, and had the most problems paying attention, reported Fallone, now at the Forest Institute of Professional Psychology.

F Sleep has long been a concern of educators. Potter-Burns Elementary School sends notes to parents reminding them to make sure students get enough sleep prior to the school's yearly achievement testing. Another school considers it important enough to include in the school's monthly newsletters. Definitely there is an impact on students' performance if they come to school tired. However, the findings may change physician practice, said Dr. Regina Benjamin, a family physician in Bayou La Batre, who reviewed the data at the Thursday's AMA meeting. "I don't ask about sleep" when evaluating academically struggling students, she noted. "I'm going to start."

G So how much sleep do kids need？ Recommended amounts range from about ten to eleven hours a night for young elementary students to 8.5 hours for teens. Fallone insists that his own second-grader get ten hours a night, even when it meant dropping soccer the season that practice didn't start until 7:30—too late for her to fit in dinner and time to wind down before she needed to be snoozing. "It's tough," he acknowledged, but "parents must believe in the importa

听力原文： Rhythm in literature is a more or less regular occurrence of certain elements of writing: a word, a phrase, an idea, a pause, a sound, or a grammatical construction. We are also accustomed to this recurrence in the alternate heavy and light beats in music. Our love for rhythm seems to be innate; witness the response of a small child to a lively music. Children love to beat on toy drums or empty boxes. They stamp their feet and chant nursery rhythms or nonsense syllables, just like primitive dancers. As children grow older, they are taught to restrain their responses to rhythm, but our love of rhythm remains. We live in rhythms; in fact we are governed by rhythms.

Physiologically, we are rhythmical. We must eat, sleep, breathe, and play regularly to maintain good health. Emotionally, we are rhythmical, too, for psychologists say that all of us feel alternate periods of being in high spirits or concentration. It usually follows that rhythm, a fundamental aspect of our lives, must be a part of any good literature works, whether poetry or prose.

Q. 15. What is rhythm in literature according to the passage？

Q. 16.What is the difference between a child's response to music and an adult's response to music？

A．A special use of words.

B．The arrangement of ideas.

M: Hi, Sally, this is Phil.

W: Great to hear from you Phil! How have you been doing？

M: To tell you the truth, I'm very worried about our final examinations next month. For one thing, I can't sleep.

W: I sympathize! I went through the same thing last year.

M: That's exactly why I'm calling you. Do you have any suggestions for coping with anxiety？ You know how I hate exams!

W: Well, last year the university offered a stress-management course at about this time. Have you been in contact with the student health services？

M: No, I haven't had time!

W: Funny, isn't it？ Just when students need help most, we can't afford the time to get it!

M: Well, perhaps I should find out more about this stress-management course. Things have got to get better!

W: I suggest you call the health services tomorrow. They open at nine a. m.

M: Thanks, ally. I'll let you know how it goes.

W: Best of luck! And have a good night's sleep!
