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" -- in 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(积累)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 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 debts, with some work, sleep debt can be repaid. Adding an extra hour or two of sleep a night is the way to catch up on sleep debt. 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 abilities that come with being well rested.
1.The example of sleep math is used to show .
A. in what case you build up a sleep debt
B. why you need six hours' sleep every night
C. why you are full of energy even when lacking sleep
D. in what case you should drink coffee to keep energetic
2.The author begins Paragraph 2 with .
A. an example B. a definition(定义) C. an argument D. a discussion
3.By saying the underlined sentence in the last paragraph, Dement means .
A. you can get enough sleep with the superman’s help
B. you can achieve your goals with a sleep debt
C. you will be in a good state with enough sleep
D. you will be clever if you accumulate sleep debt

Every day, life is made and lost. Every day, life goes on. Every day we experience some of the most important parts of life and may not even realize it: love, generosity, and perseverance. These values aren’t just important to us; they make the world what it is.
Scientists say that gravitaional(重力的)force makes the world turn, but some people say that love makes it go round. Love can be found anywhere: in families, friends, even complete strangers. Even if you can’t see it, you know it’s there.
Love may connect people all over the world, but what would the world be without generosity? Whether after a national disaster, or a school fund-raiser, one thing is certain----it is better to give than to receive. Generosity is found everywhere and whether it’s a large or small act, it makes a difference. Sometimes, though, it takes effort to be generous, which leads us to perseverance.
Founding a country, riding a bike, or finishing an essay, these are all finished with perseverance. Perseverance is the one thing that can help us achieve whatever we want. It is what helps scientists to discover cures for diseases, and athletes to become champions.
There is an infinite(无穷的) number of things we value, but without love, generosity and perseverance, we just don’t think that our life or the world would be the way it is.
1. The underlined word “it” in the second paragraph refers to “________”.
A. the world B. gravitational force
C. value D. experience
2. To be generous, the author thinks________.
A. you needn’t make efforts B. you should be qualified
C. you should give all you have D. you will find it good to give
3. Which of the following statements is TRUE according to the passage?
A. Perseverance is the only thing that can halp us to achieve success.
B. People don’t understand the life they are experiencing at all.
C. We can find love in complete strangers sometimes.
D. What the world is like depends on gravity and love.
4. What would be the best title for the passage?
A. Success and Failure B. Three Values
C. Endless Love D. Life Full of Hope

Hundreds of children are being treated for sleep problems in Wales every year. In some cases, babies, infants and teenagers have been admitted to hospital while in north Wales alone.
The Children’s Sleep Charity said many children were suffering from lack of sleep mainly because of technology use. Public Health Wales said sleep was as important to a child’s health as healthy eating and exercise, and children with poor sleep patterns were more likely to be fat.
Statistics obtained under the Freedom of Information Act by BBC Wales found at least 408 children have been admitted to hospitals across Wales suffering from sleep disorders since March 2013.
Children aged between 0 and4 made up the highest number of inpatients (住院病人), with some newborns being treated for sleep-related problems from the day of birth.
Vicki Dawson, who set up the Children’s Sleep Charity (CSC), said sleepless nights were putting both children and parents in anxiety. “Their weight and growth may also be affected as well as their mental health,” she said.
Teachers said children showing signs of sleep shortage and tiredness in class were a concern as they couldn’t concentrate for long periods.
Psychologist Amy McClelland, of Sleep Wales, said a common problem was children being “over excited” and “not having the chance to relax property” before bed and families should get back to basics. “Think 1950s family home. Dinner as a family, read, chat, a film maybe, lights off and then bed.” She added.
1.What’s the main reason why children are short of sleep?
A. Less exercise. B. Eating habits.
C. Sleep patterns. D. Technology use.
2.Who are the majority of the inpatients with sleep-related disorders?
A. Teenagers. B. Infants.
C. Teachers. D. Parents.
3.What can we infer from what Amy McClelland said?
A. Relaxation has a bad effect on children.
B. Chatting and films make children sleep more.
C. Being too excited is good for sleep habits.
D. It is difficult for children to read before bed.
4.What is the best title for the text?
A. Ways to Treat Sleep Problems B. Sleep Habits of Welsh Children
C. Sleep Problems of Welsh Children D. The Problems of Welsh Children
