It doesn't matter when or how long a person sleeps, but everyone needs some rest to stay alive. That's what all doctors' thought, until they heard about Jercy Page. Jercy Page, it was said, never slept. Could this be true.'? The doctors decided to see this strange man by themselves.
Jercy Page was ninety years old when the doctors came to his home in New Jersey. They thought for sure that he got some sleep of some kind. So they stayed with him and watched every movement he made. But they were surprised. Though they watched him hour after hour and day after day, they never saw Jercy Page sleeping. Actually, he did not even own a bed. He never needed one.
The only rest that Jercy Page got was sitting in a comfortable chair and reading newspapers. The doctors were puzzled by this strange continuous sleeplessness. They asked him many questions, hoping to find an answer. They found only one answer that might explain his condition. Page remembered some talk about his mother having been injured several days before he was born. But that was all. Was this the real reason? No one could be sure.
The main idea of this passage is that ______.
A.large numbers of people do not need sleep
B.a person was found who actually didn't need any sleep
C.everyone needs some sleep to stay alive
D.people can live longer by trying not to sleep

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.
What can we learn from the passage?
A.Sleep hours is the most important factor affecting survival.
B.Going to bed and getting up early improve health.
C.Less sleep is more harmful than over sufficient sleep to people.
D.People have different demands of sleep hours.

<span style="margin: 0px; padding: 0px; font-family: &39;times new roman&39;, serif;">Artis considered by many people to be little more than a decorative means ofgiving pleasure. This is not always the case, however, at times, art may beseen to have purely functional side as well. Such could be said of the sandpaintings of the Navaho Indians of the American Southwest; these have amedicinal as well as an artistic purpose.</span>
<span style="margin: 0px; padding: 0px; font-family: &39;times new roman&39;, serif;">According to Navaho traditions, one who suffers from either a mental orphysical illness has in some way disturbed or come in contact with thesupernatural—perhaps a certain animal, a ghost, or the dead. To counteract thisevil contact, the sick person or one of his relatives will attract a powerfulsupernatural being. During the ceremony, which may last from 2to 9days, the“singer” will produce a sand painting on the floor of the Navaho house. On thelast day of the ceremony, the patient will sit on this sand painting and the“singer” will rub the sick parts of the patient’s body with sand from aspecific figure in the sand painting. In this way the patient absorbs the powerof that particular supernatural being and becomes strong like it. After theceremony, the sand painting is then destroyed and disposed of so its power willnot harm anyone.</span>
<span style="margin: 0px; padding: 0px; font-family: &39;times new roman&39;, serif;">Theart of sand painting is handed down from old “singers” to their students. Thematerials used are easily found in the areas the Navaho inhabit: brown, red,yellow, and white sandstone, which is ground into powder by being crushedbetween two stones much as corn is ground into flour. The “singer” holds asmall amount of this sand in his hand and lets it flow between his thumb andforefinger onto a clean, flat surface on the floor. With a steady hand andgreat patience, he is thus able to create designs of people, snakes and othercreatures that have power in the Navaho belief system.</span>
