Let's do some sleep math. You lost two hours of sleep every night last week because of a big project due on Friday. On Saturday and Sunday, you slept in, getting four extra hours. On Monday morning, you were feeling so bright-eyed, and you only had one cup of coffee, instead of your usual two. But don't be cheated by your energy: You're still carrying around a heavy load of sleepiness, or what experts call " sleep debt "win this case something like six hours, almost a full night's sleep.
Sleep debt is the difference between the amount of sleep you should be getting and the amount you actually get. It's a deficit (赤字)that grows every time we skim some extra minutes off our nightly sleep. "People accumulate sleep debt gradually without being noticed," says psychiatrist William C. Dement, founder of the Stanford University Sleep Research Centre. Studies show that such short-term lack of sleep
leads to a foggy brain, worsened vision, and trouble remembering. Long-term effects include obesity, insulin(胰岛素) resistance, and heart disease. A survey by the National Sleep Foundation reports that we're losing one hour of sleep each night —more than two full weeks of sleep each year.
The good news is that, like all debt, with some work, sleep debt can be repaid. Adding an extra hour or two of sleep a night is the way to catch up. For the long-term lack of sleep, take it easy for a few months to get back into a natural sleep pattern. Go to bed when you are tired, and allow your body to wake you in the morning (no alarm clock allowed). You may find yourself catatonic (有紧张感的)in the beginning of the recovery cycle: Expect to have ten hours' shut-eye per night. As the days pass, however, the amount of sleeping time will gradually decrease.
So earn back that lost sleep —and follow the orders of your inner sleep needs, and you'll feel better. "When you put away sleep debt, you become superman." Says Stanford's Dement, talking about the improved mental and physical capabilities that come with being well rested.

Dear College Dean
It is my understanding that this college has received a large donation to be used to improve the quality of life for students: expand the bookstore or add computers to the computer lad. It is the tradition of his school to promote education and to be the pioneer of new technology. That is why I strongly argue in favor of the addition of more computers to the computer lab.
Although expanding the campus bookstore to include CDs, gif
ts, and a snack bar will give a nicer look to the college, we have to think about a greater goal and a more practical way to enhance the quality of life for students. What do we want for our students and our college? Do we want our college to be known as a place with a great bookstore where you can find CDs and gifts, or as a place where the students can explore and research in their field using the best tools provided by technology? In addition, there are already several snack bars on campus, and there are music stores nearby, so students do not depend on the college bookstore for these things.
We live in a highly technological world and computers play an increasingly important role in how we live. As a learning institution, this college has the responsibility to offer its students the best technology to help them prepare for their future. Many students will be expected to be familiar with the latest software and other tools when they go on to work or to graduate school.
While they are in college, students find they are expected to use computers. Many professors expect students to use computers to do homework or to complete projects. Students are asked to create PowerPoint presentations and use spreadsheets and database programs, as well as to research many topics on the Internet. Since students are competing for good grades, those who have limited access to computers are at a great disadvantage. Furthermore, being able to do projects using the computer enhances the process of learning, giving students the opportunity to find information that without a computer would be much more difficult to find.
If there are more computers, students will also be able to complete their work more efficiently. No more will they have to wait in line, paper and disk in hand, while scanning the room for an empty chair and computer. No longer will they have to sit and wait while an outdated computer struggles to follow their commands. Having more new and faster computers available will enable students to finish their work more quickly.
The more computers are used in society the more colleges will depend on them as a tool of teaching and learning. Making computers more available to students facilitates their learning process by making the process easier, more interesting, more engaging, and in the process enhancing their quality of lifeThe purpose of the author in writing the passage is .
| A．to describe the problems caused by lack of computers |
| B．to explain why students are in great need of computers |
| C．to tell us what benefits students can gain from computers |
| D．to persuade the Dean to purchase more advanced computers |
From the passage we can infer that .
| A．present computers in the college cannot meet the demands of the students |
| B．computers in the college will be updated to meet the student's demands soon |
C．the college has  the responsibility to help the students to prepare for their future |
| D．it is also necessary to expand the college bookstore by using part of the donation |
In paragraph 4, the author mainly wants to tell us that.
| A．computers are beneficial to students' academic success |
| B．computers are helpful to student's competition for success |
| C．students find it convenient to do assignments by using computers |
| D．students wish to use the money to buy more advanced computers |
Which of the following shows the organization of the passage?
Most people feel lonely sometimes, but it usually only lasts a few minutes or a few hours. This kind of loneliness is not serious. In fact, it is quite normal. For some people, though, loneliness can last for years. Now researchers say there are three different types of loneliness.
The first kind of loneliness is temporary. This is the most common type. It usually disappears quickly and does not require any special attention. The second kind, situational loneliness, is a natural result of a particular situation－for example, the death of a loved one, or moving to a new place. Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually does not last for more than a year. Situational loneliness Is easy to understand and to predict.
The third kind of loneliness is the most severe. Unlike the second type, chronic loneliness usually lasts more than two years and has no specific cause. People who experience habitual loneliness have problem socializing and becoming close to others unfortunately, many chronically lonely people think there is little or nothing they can do to improve their condition.
Many researchers agree that the loneliest people are between the ages 18 and 25, so a group of psychologists decided to study a group of college students. They found that more than 50% of the students were situationally lonely at the beginning of the term as a result of their new circumstances, but had adjusted after a few months, 13% were still lonely after seven months due to shyness and fear. They felt very uncomfortable meeting strangers, even though they understood that their fear was not reasonable. The situationally lonely students overcame their loneliness by making new friends, but the chronically lonely remained unhappy because they were afraid to do so.
Psychologists are trying to find ways to help habitually lonely people for two reasons: First of all, they are unhappy and unable to socialize and there is a connection between chronic loneliness and serious illness such as heart disease. While temporary and situational loneliness can be a normal, healthy part of life, chronic loneliness can be a very sad, and sometimes dangerous condition. The passage mainly talks about .

A round of applause, please, for the Indian man who recently sang for 80 hours straight, setting a new Guinness world record. It’s an impressive feat, to be sure, but let’s just hope he still has a voice. According to Indian newspapers, Rajesh Burbure has been told to keep silent for several days so his vocal cords (声带) can heal.
It was reported that Burbure and his family are in a celebratory mood. “It’s a proud moment for all of us,” his wife told DNAIndia.com.
I, on the other hand, am unable to share their ent
husiasm. Don’t get me wrong: I hope the 35-year-old Burbure lives forever, sells a million records and becomes an international celebrity. But his record–singing for 80 hours straight–is about as meaningful as most of the other curious but crazy feats listed in the Guinness Book of World Records.
Granted , I’m not qualified to speak on the subject. I’ve got no world records to my name– and I never expect to have any. Then again, maybe I am qualified to speak for those of us who have better things to do than train for years to sing an 80-hour medley (混合曲) of pop songs.
But let’s not just pick on poor Burbure. He’s not the only person chasing meaningless accolades. The Guinness Book of World Records is full of the names of people who at one time grew the longest hair, or built the biggest bicycle, or baked the largest cheesecake.
To all of these enterprising (有进取心的) souls I ask, simply, “What was it all for?”
Congratulations! For all of your painstaking effort, you becam
e a footnote in a thick book that no one reads, except for you and the person who will eventually surpass you–with one more hour of singing, a few more centimeters of steel or a few more pounds of cheese.
After all, records are made to be broken.From the text, we can learn that the author .
A．has no Guinness records, so he admires Burbures’ fea t |
| B．feels it is a pity he was not invited to share the happiness with the Burbures |
| C．thinks singing for 80 hours straight is completely meaningless |
| D．is quite worried about Burbure’s vocal cords |
Before someone wins a Guinness record, he or she has to .
| A．become an international celebrity |
| B．know all about Guinness record |
| C．practice a great deal |
| D．bear great stress for fear of injury |
We can infer from the article that .
| A．after the 80 hours of singing, Burbure could no longer speak |
| B．Burbure’ wife didn’t support his attempt to make a Guinness record |
| C．many have criticized Burbure for his stupid behavior |
| D．challenging a Guinness record may be harmful to the health |
The author’s attitude to the Guinness world records mentioned in the passage is .
| A．positive | B．impressed |
| C．negative | D．touched |
What is the best title for the passage?
| A．What Was the Point? |
| B．Records Are Made to be Broken |
| C．A New Indian Guinness Record |
| D．The Guinness Book Is Boring |
