Colleges are starting to wake up to how sleep deprivation(剥夺) cuts into the academic and athletic performance of their students. All-nighters have become a habit in higher education, but a handful of small new studies help document the consequences.
A study at St. Lawrence University in Canton, N.Y., showed what may seem obvious to most: All-nighters are not an effective way to succeed in school.
“You can’t do your best work when you’re sleep-deprived,” says psychology professor Pamela Thacher, who wrote the study. Thacher, studied the sleeping patterns and grades of 111 students to see the relationship between sleep and their GPAs.
Two-thirds of the students reported that they had pulled at least one all-nighter during a semester. Many students believe that it’s a “rite of passage”(标志) to stay up all night during college and that “it’s kind of fun,” Thacher says.
But “if you use all-nighters, your GPA is slightly lower on average,” Thacher says. “Pulling all-nighters gives in your (overall) sleep” and makes it difficult to reach full academic potential.
Short-term side effects of sleep deprivation include delayed reactions and tendencies to make mistakes.
A Stanford University study may help persuade at least student athletes to make more time for bed. Cheri Mah, a graduate researcher at Stanford, worked with six basketball players, who all ran faster and made more shots over a period in which they slept at least 10 hours a night.
“Athletes who get an extra amount of sleep are more likely to improve their performance in a game,” says Mah, who released results from an ongoing study in June. “It’s not common knowledge, because if people understood how much of a difference (getting more sleep could make athletically,” they’d apply it more to their lives and not focus solely on nutrition and exercise.
66．According to the study at St. Lawrence University, ___________.
A．one can reach his potential by staying up late
B．it takes one all night to recite a passage
C．the less one sleeps, the more effective his work is
D．all-nighters affect one’s academic performance

68．Which of the following statements is true?
A．All-nighters are a short-cut to success in school.
B．All-nighters can make one’s GPAs much higher.
C．Staying up late tends to react slowly and make mistakes.
D．The study may help persuade all students to sleep well.
69．According to Cheri Mah, _______.
A．athletes improve their performance only by means of nutrition and exercise
B．it is known to all that those who get extra sleep perform better
C．people don’t understand getting more sleep can make a difference
D．athletes should sleep as much as possible to run faster
70．What is this passage mainly concerned about?

B．College students’ performance suffering from lack of sleep.
C．Short-term side effects of sleep deprivation.
D．A Stanford University study on athletes’ sleep
查看习题详情和答案>>Some people seem easy to understand：their character appears obvious on first meeting. Appearances, however, can be deceptive. For thirty years now I have been studying my fellowmen. I don’t know very much about them. I shrug my shoulders when people tell me that their first impressions of a person are always right. I think they must have small insight or great vanity. For my own part I find that the longer I know people, the more they puzzle me.
I read in this morning's paper that Edward Hyde Burton had died. He was a merchant and he had been in business in Japan for many years.Once he gave me a great surprise. Unless I had heard the story from his own lips, I’d never have velieved that he was capable of such an action. He was always neatly and quietly dressed in accordance with his age and position. He didn’t talk much, but what he said was sensible. Tou couldn’;t imagine he’d possible raise his voice in anger. Here was a man who attracted you because you felt in him a real love for his fellows. He’d tell with point a good and spicy story, and in his youth he’d been something of an athete. He was a rich man and he’d made every penny himself. I suppose one thing that made you like him was that he was so weak; he arounsed your instinets（本能）of protection. TYou felt he couldn’t bear to hurt a fly.
One afternoon Burton told me a “funny” story in a quiet, dry humour:
“There was a namesake（同名人）of mine, who was the best bridge player I ever met. He seemed to have a fantastic instinct about the cards. I used to play with him a lot.”
“He was handsome in a way with curly hair and pink-and- white cleeks. Women thought a lot of him. There was no harm in him, he was only wild. Pf course he drank too much. He won a good deal of my money by card-playing.”
“One day he came to me when he went broke. He came to see me in my office and asked me for a job. I asked him how old he was.
“’Thirty-five’, he said.”
"'And what have you been doing hitherto?' I asked him.
"'Well, nothing very much,' he said.
"'I'm afraid I can't do anything for you just yet,' I said. 'Come back and see me in another thirty-five years, and I'll see what I can do.'
"He didn't move. He went rather pale. He hesitated for a moment and then he told me that he had had bad luck at cards for some time. He hadn't been willing to stick to bridge, he'd been playing poker, and he'd got trimmed. He hadn't a penny. He'd pawned everything he had. He couldn't pay his hotel bill and they wouldn't give him any more credit. He was down and out. If he couldn't get something to do he'd have to commit suicide.
"I looked at him for a bit. I could see now that he was all to pieces. He'd been drinking more than usual and he looked fifty. The girls wouldn't have thought so much of him if they'd seen him then.
"I got some glimmering of what he was driving at. I've known too many men who were little tin gods at their university.
“Suddenly I had an idea.” Pausing in his story, Burton turned to me. “When I was young I swam over three miles round the beacon（灯塔）and landed at the river of Tarumi. It’s rather difficult on account of the currents round the beacon. Well, I told my young fellow about it and I said that if he’d do it I’d give him a job.
“I could see he was rather taken aback. He was not in good condition for sports. He looked at me for a moment and then he nodded.”
“I told him I’d drive round to the river at half past twelve and meet him.
"Done,"he said.
“I wished him good luck and he left me.I had a lot of work to do that morning and I only just managed to the creek at Tarumi at half past twelve.But I needn't have hurried;he never turned up
“Did he funk it at the last moment?” I asked.
“No,he didn't funk it. He started all right. But of course he'd ruined his constitution by drink. The currents round the beacon were more than he could manage. We didn't get the body for about three days
I didn't say anything for a moment or two.I was a trifle shocked.Then I asked.
“When you made him that offer of a job, did you know he'd be drowned?'
He looked at me with his kind blue eyes, smiling. "Well,I hadn't got a vacancy in my office at the moment.'
