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.

I was standing on the corner of the street with a cigar that I wanted to light. I had no match. I waited till a decent, ordinary man came along. Then I said: "Excuse me, sir, but could you oblige me with the loan of a match？" "A match？" he said, "why, certainly." Then he unbuttoned his overcoat and put his hand in the pocket of his waistcoat. "I know I have one," he went on, "and I'd almost swear it's in the bottom pocket — or, hold on, though, I guess it may be in the top — just wait till I put these parcels down on the sidewalk." "Oh, don't trouble," I said. "It's really of no consequence." "Oh, it's no trouble, I'll have it in a minute; I know there must be one in here somewhere"—he was digging his fingers into his pockets as he spoke — "but you see this isn't the waistcoat that I generally…" I saw that the man was getting excited about it. "Well, never mind," I protested; "if that isn't the waistcoat that you generally — why, it doesn't matter." "Hold on, now, hold on!" the man said. "I've got one of the cursed things in here somewhere. I guess it must be in with my watch. No, it's not there either. Wait till I try my coat. If that damned tailor only knew enough to make a pocket so that a man could get at it!" He was getting pretty well worked up now. He had thrown down his walking-stick and was searching his pockets with his teeth set. "It's that cursed young boy of mine," he exasperated; "this comes of his fooling in my pockets. By God! perhaps I won't warm him up when I get home. Say, I'll bet that it's in my hippocket. You just hold up the tail of my overcoat a second till I…" "No, no," I protested again,"please don't take all this trouble, it really doesn't matter. I'm sure you needn't take off your overcoat, and oh, pray don't throw away your letters and things in the snow like that, and tear out your pockets by the roots! Please, please don't trample over your overcoat and put your feet through the parcels. I do hate to hear you swearing at your little boy, with that peculiar grumble in your voice. Don't — please don't tear your clothes so savagely." Suddenly the man gave a grunt of joy, and drew his hand up from inside the lining of his coat. "I've got it," he cried. "Here you are!" Then he brought it out under the light. It was a toothpick. Yielding to the impulse of the moment I pushed him under the wheels of a trolley-car and ran.
