A full night's sleep'/Not everyone needs it. The truism that all adults need at least eight hours of sleep a night for good health should be put to rest by mounting evidence that less may be better.①
People who sleep about seven hours a night live the longest, three huge studies have found, the newest out in the February issue of the journal Sleep. Still, many sleep experts say lots of adults get too little rest, and that can lead to dangerous health problems.
In the latest report from Japanese researchers, 104,010 adults were followed for about 10 years. At the start the participants answered questionnaires about their sleep patterns and about their health mental health and lifestyle. habits, which also can affect survival. After accounting for all of these factors, adults getting all average of seven hours had the lowest death rates. Surprisingly, less sleep ,even as little as four hours a night, didn't significantly increase deaths for men and only lowered survival for women if they averagde less than four hours② But adults who slept longer than seven hours, particulary women, were more likely to die during the 10 years.
Two other major published studies and a dozen smaller ones came to similar conclusions, says psychiatrist Daniel Kripke, a sleep researcher at the University of California-San Diego School of Medicine. Doctors shouldn't tell all of their patients to get at least eight hours of sleep, he says in an editorial in the journal. Hormonal changes triggered by darkness or other unknown biological effects from long sleep could be affecting survival,③ Kripke，says.
But short sleepers may suffer other bad effects. In his brief studies, those sleeping four to five and a half hours did poorly on tests that measure memory, clear thinking and the ability to pay attention, "and they did progressively worse as the week went on," says David Dinges of the University of Pennsylvania School of Medicine. Adults who slept about seven hours performed best, he says. Other small studies have found adults who sleep less than six hours may be at higher risk for some diseases like diabetes and overweight. And sleep deprivation also causes car crashes, Dinges says. "People should get as many hours sleep, p as they need to feel rested," Kripke says, adding that there's no proof that shortening sleep will lengthen life. s1eep need is partly genetic and may be determined by other factors that also influence life span, he says.

B．Going to bed and getting up early improve health.

A good night's sleep may help your brain permanently file away lessons learned during the day. But, according to a new study, the brain begins processing and storing those memories long before it's time for bed-and continues to do so even while you're thinking about and doing other things.
Recent studies have shown that the parts of the brain that we use to learn a task become active again during sleep. This activity, scientists suggest, could be the brain transferring memories from short-term to long-term storage.
But the brain doesn't necessarily wait until the lights are out to begin processing those memories.
To find out how the brain handles memories during waking hours, scientists gave 15 volunteers two tasks, each requiring different parts of the brain to learn. In one task, the subjects learned how to navigate a virtual town and then searched the town for an object. In the second task, they learned to predict where a sequence of dots would appear on a screen.
Using a special machine, the researchers scanned the volunteers' brains right before and right after the tasks. They compared the two images to see whether the regions of the brain involved in learning the task were still active even after the task was completed.
After a break, the scientists took a third image of each participant's brain. They wanted to determine whether these regions in the brain continued to be active after snore time had passed.
They discovered that, for at least an hour after learning a task, the brain stays active. It appears to continue processing the new information.
Furthermore, the images showed that distracting the subjects doesn't affect their ability to store memories. The processing continues even when they're thinking about or doing other things.
Some scientists say this could mean that sleep isn't essential for storing memories. Others disagree. Until that's settled, it's probably still better to be on the safe side, getting plenty of sleep.
According to the passage, ______.
A．a good night's sleep helps your brain permanently file away lessons learned during the day.
B．the brain has to wait until the lights are out to begin processing those memories
C．perhaps it's safe for anyone to get plenty of sleep when it has not been proved unnecessary for memory
D．attracting the subjects doesn't affect their ability to store memories.

听力原文： Each night we alternate between two kinds of sleep: active sleep and passive sleep. The passive sleep gives our body the rest that is needed, and prepares us for active sleep, in which dreaming takes place. And we arc beginning to understand the importance of the dream period in our sleep cycles.
In passive sleep the body is at rest. We move very little. And the brain becomes very inactive, ff a person continues to sleep, she or he enters anew period, a more active period. The body goes through several changes: the brain temperature rises, blood in the brain increases, the body becomes very still and the brain goes into active state. And as the brain goes active, the eyes begin to move rapidly. And that is the sign of another change---the person is dreaming. Throughout the night, people alternate between passive and active sleep. Doctors have studied the sleep cycle and have found that everyone dreams---in fact, that everyone needs to dream in order to stay healthy. It appears we need both kind of sleep. We need passive sleep in order to rest our bodies. We need active sleep in order to dream. And dreaming helps us to rest our minds,
What does not happen in the brain in the active sleep？
A．The brain becomes very active.
B．The brain becomes very inactive.
C．The brain temperature rises.
D．The brain blood rises.
