Most teens need about 8 to more than 9 hours of sleep each night.The right amount of sleep is necessary for anyone who wants to do well in a test or play sports without tripping over their feet. Unfortunately,though,many teens don’t get enough sleep.
_______________? Early starting time in some schools may play a role in this sleep deficit (不足).Teens who fall asleep after midnight may still have to get up early for school,meaning that they may only shorten into 6 or 7 hours of sleep a night.A couple of hours of missed sleep a night may not seem like a big deal,but can create a noticeable sleep deficit over time.
Why is sleep important? Sleep deficit affects everything from a person’s ability to pay attention in class to his or her mood.Research shows that more than 20% of high school students fall asleep in class,and experts have been able to tie lost sleep to poorer grades.Lack of sleep also damages teens’ ability to do their best in sports.Slowed responses and less concentration(专注)caused by sleep deficit don’t just affect school or sports performance,though.Lack of sleep slows reaction time,which can be life threatening for people who drive.The National Highway Safety Traffic Administration reports that 1,500 people are killed every year in crashes caused by drivers between the ages of 15 and 24 who are simply tired.Lack of sleep has also been linked to emotional troubles, such as feelings of sadness and depression.Sleep helps keep us physically healthy,too,by slowing our body’s systems enough to re-energize us after everyday activities.
How do I know if I’m getting enough sleep? Even if you think you’re getting enough sleep, you may not be.Here are some of the signs that you may need more sleep: (1) difficulty in waking up in the morning;(2) inability to focus;(3) falling asleep during classes; (4) feelings of anxiety and even depression(忧郁).Recently,some researchers,parents,and teachers have suggested that middle and high school classes begin later in the morning to meet teens’ need for more sleep.Some schools have already tried later starting time.You and your friends,parents,and teachers can call up for later start time at your school,but in the meantime you’ll have to make changes on your own first.
1.Which is the best choice for the blank in Paragraph 2?
A.What does sleep deficit mean
B.How many hours do teens sleep a night

D.Why do teens now need to sleep more
2.What can we learn from the passage?
A.1500 drivers between ages of 15 and 24 in America are killed a year.
B.Lack of sleep has bad influence on both life and school performance.
C.Sleep helps to keep us healthy by energizing our everyday activities.
D.Poor performance in study and sports has little relation with lost sleep.
3.What is the writer’s main purpose in writing this passage?
A.To explain the reason why teens are lack of sleep.
B.To draw people’s attention to teens’ sleeping problem.
C.To introduce that we have the problem of sleep shortage.

阅读短文,并根据短文内容判断短文后面句子的正误。正确为T错误为F。
Fire can help people in many ways. But it can be very dangerous. Fire can heat water, warm houses, give light and cook. But fire can burn things, too. It can burn trees, houses, animals or people. Sometimes a big fire can burn forests.
Nobody knows for sure how people began to use fire. But there are many interesting stories about the first time a man or a woman started a fire. One story from Australia tells about a man very, very long time ago. He went up to the sun by a rope(绳子)and brought fire down.
Today people know how to make a fire with matches. Children sometimes like to play with them. But matches can be very dangerous. One match can burn a piece of paper, and then it might burn a house. A small fire can become a big fire very fast. Fire kills many people every year. So you must be careful with matches. You should also learn to put out fire. Fire needs oxygen(氧气).Without oxygen it will die. Cover fire with water, sand or sometimes with your coat. This keeps the air away from fire and kills it. Be careful with fire, and it will help you.
Be careless with fire, and it will burn you.
1.We are not sure how people began to use fire.
2.Children mustn't play with matches because they can be dangerous.
3.If there is no oxygen, fire will die.
4.small fire is not dangerous at all.
5.You don't need to know how to put out a fire.
