Unexpected connection between sleep and academic performance has been recently discovered.
Researchers have found that insufficient sleep and tiredness increase a person's risk of developing severe medical conditions, such as obesity (肥胖症),high blood sugar levels, and heart disease. Now, a new study has found that getting sufficient sleep is also the key to improving academic performance.
Jeffrey Gross, the university science professor who led the research, was not trying to find the relationship between sleep and grades when he handed out smartwatches to the 100 students in his chemistry class. Instead, the professor hoped the wrist-worn devices, which track a personas physical activity, would show a connection between exercise and academic achievements.
While Grosses data showed no relationship between these two factors, the study found something surprising. As the researchers were analyzing their data, they noticed that there was a linear (线性的)relationship between the average amount of sleep the students got and their results in the course's 11 quizzes, three midterm tests, and the final exam.
Even more interesting, it was not sufficient for students to just head to bed early the night before a test Instead, it's the sleep you get during the days when learning is happening that matters most.
When students went to bed each night was similarly important. Those who went to bed in the early hours of the morning performed poorly, even if the total sleep time was the same as a higher-performing student. "When you go to bed matters," Gross says. “If you go to bed at 10, or 12, or 1 at night, and sleep for seven hours, your performance is the same. But if you go to bed after 2, your performance starts to go down even if you get the same seven hours' sleep. So, quantity isn't everything."
Perhaps the most interesting was the huge impact that small differences in sleep patterns had on the students' grades. The overall course grades of students averaging six and a half hours of sleep each night were 25% lower than students who averaged just one hour more sleep. Similarly, students who varied their bedtime by even one hour each night had grades that dropped 45% below those with more regular bedtime.
Who knew getting straight AM just required some extra sleep?
1.Based on his original objective, which best describes Professor Gross's research findings?
A.Convincing. B.Complete.
C.Accidental. D.Doubtful.
2.Who were the people taking part in the study?
A.Middle school chemistry students.
B.Volunteers from different universities.
C.University student athletes.
D.Professor Gross's own students.
3.How did Professor Gross's team measure students' academic performance?
A.Making the students wear special watches.
B.Using the students' normal test and quiz grades.
C.Giving the students regular quizzes after class.
D.Using students' university entrance test results.
4.Based on the study's fin dings, who is likely to perform best academically?
A.A student who has a good night's sleep the night before an important test.
B.A student who sleeps from 11 pm to 6 a.m. each day.
C.A student whose normal bedtime varies between 9 p.m. and 12 p.m.
D.A student who sleeps for a total of 7 hours each night.

The justification for a university is that it preserves the connection between knowledge and the zest of life, by uniting the young and the old in the imaginative consideration of learning. The university imparts information, but it imparts it imaginatively. At least, this is the function which it should perform for society. A university which fails in this respect has no reason for existence. This atmosphere of excitement, arising from imaginative consideration, transforms knowledge. A fact is no longer a burden on the memory, it is energizing as the poet of our dreams and as the architect of our purposes.
Imagination is not to be divorced from the facts: it is a way of illuminating the facts. It works by eliciting the general principles which apply to the facts, as they exist, and then by an intellectual survey of alternative possibilities which are consistent with those principles. It enables men to construct an intellectual vision of a new world, and it preserves the zest of life by the suggestion of satisfying purposes.
Youth is imaginative, and if the imagination be strengthened by discipline, this energy of imagination can in great measure be preserved through life. The tragedy of the world is that those who are imaginative have but slight experience, and those who are experienced have feeble imagination. Fools act on imagination without knowledge; pedants(学究)act on knowledge without imagination. The task of university is to weld together imagination and experience.
1. The main theme of the passage is ____.
A. the access to knowledge in university B. the function of universities
C. the role of imagination in our lives
D. the relationship between imagination and experience
2. According to the passage, the justification for a university is that ____.
A. it presents facts and experience to young and old
B. it imparts knowledge to imaginative people
C. it combines imagination with knowledge and experience
D. it enables men to construct an intellectual vision of the world
3. The word “eliciting” in paragraph 2 probably means ____.
A. applying B. challenging C. drawing forth D. preserving
4. Which of the following is NOT discussed as one of the things imagination can do?
A. It makes our life exciting and worthwhile. B. It helps us to understand the world.
C. It helps us to formulate Laws about the facts. D. It provides inspiration to the artists.
5. According to the author, the tragedy of the world is that ____.
A. our energy of imagination cannot be preserved B. our imagination is seldom disciplined
C. we grow old inevitably D. too many people are either fools or pedants

We walk, talk and sleep with our phones. But are we more — or less-connected? Just as remarkable as the power of mobility, over everything from love to global development, is how fast it all happened. It is hard to think of any tool, any instrument, any object in history with which so many developed so close a relationship so quickly as we have with our phones. Not the knife or match, the pen or page. Only money comes close—always at hand, don't leave home without it. But most of us don't take a wallet to bed with us. don't reach for it and check it every few minutes, and however useful money is in pursuit of fame, romance, revolution, it is inert compared with a smart phone — which can replace your wallet now anyway.
So how do we feel about this? To better understand attitudes about mass mobility, Time, in cooperation with Qualcomm, started the Time Mobility Poll, a survey of close to 5,000 people of all age groups and income levels in eight countries. Even the best survey can be only a snapshot in time, but this is revealing a lot about both where we are now and where the mobile wave is taking us next.
Not for a day — in most cases not even for an hour. In Time's Poll, 1 in 4 people check it every 30 minutes, 1 in 5 every 10 minutes. A third of respondents admitted that being without their mobile for even short periods leaves them feeling anxious. It is a form of sustenance, that constant feed of news and notes and nonsense, to be the point that twice as many people would pick their phones over their lunch if forced to choose. Three-quarters of 25-to 29-year-olds sleep with their phones.
Americans are grateful for the connection and convenience their phones provide, helping them search for a lower price, navigate a strange city, expand a customer base or track their health and finances, their family and friends. But in some ways Americans are still ambivalent (矛盾的); more than 9 in 10 Brazilians and Indians agreed that being constantly connected is mostly a good thing. America's 76% was actually the lowest score.
1.What can have a comparison with phones?
A.A pen. B.A knife.
C.A match. D.Money.
2.It can be inferred that a smart phone can also have the function of ______
A.paying bills. B.helping sleep.
C.pursuit money. D.cutting things.
3.Why did Time start the Time Mobility Poll?
A.Because it wanted to cooperate with Qualcomm.
B.Because it wanted to know where the mobile wave was taking us.
C.Because it wanted to learn people's attitudes to mass mobility
D.Because it wanted to know how well the mobile wave went.
4.What does Paragraph 3 mainly tell us?
A.Mobile phones have become a tool to sleep with.
B.Mobile phones have become a way to get news.
C.Mobile phones have become a tool to order food.
D.Mobile phones have become a must in daily life.
5.According to the passage. Americans are less ______.
A.likely to show appreciation to their phones.
B.constantly connected than Indians.
C.likely to search for a lower price.
D.likely to find ways in a strange city.

Reducing the amount of sleep affects students’ performance at school. An American study asked schoolteachers to look at the effects of sleep restriction(限制) on children between six and twelve years of age. The teachers found that children who stayed up late had trouble thinking clearly and had more learning problems.
1. Doctor Fallone now works at the Forest Institute of Professional Psychology in Springfield, Missouri. He presented the results last month at a science reporter conference in Washington, D. C.. The publication Sleep also reported the findings.
The teachers were asked to complete weekly performance reports on seventy-four schoolchildren. The study lasted three weeks. During that period, Doctor Fallone and his team controlled the amount of sleep the children received.
2. During another week, every child was kept awake later than normal. Each night, the youngest boys and girls had less than eight hours of sleep. The older ones were limited to six and a half hours. During the final week of the study, each child received no less than ten hours of sleep a night.
The teachers were not told about how much sleep the students received. The study found that students who received eight hours or less had the most difficult remembering old information. 3.
