Have you ever heard the saying "If you want a friend, be one"? If you want to make friends with others, you should be friendly to them first.

      Here is how one new teacher made friends with the students in her class on the first day of school. As the bell rang, the teacher smiled （微笑） at each student. Then she said in a quiet voice,"Good morning. How nice it is to have all of you in my class this year. I'd like to know each of you. I am sure we will enjoy working together." Her voice was sweet（甜美的） and her look was friendly, so everyone felt happy.

      She told the students her name and wrote it on the blackboard. Then she told them some of the things she liked to do and she hoped to do with them during the year. Then she said to the boys and girls, "Now you know my name and the things I like and I want to know your names and the things you like."

      Could you make friends by doing the same as this teacher did?

      One way of getting to know girls and boys in your class is to find out more about them. People often make friends with those who are the same as them. You play the same games and go on vacations together. It is a good way to make friends.

In China , more and more middle school students are getting shorter sleeping time than before. Most students sleep less than nine hours every night, because they have much homework to do. Some homework is given by their teachers, and some by their parents. Also, some students don't know how to save time. They are not careful enough while they do their homework, so it takes them a lot of time. Some students spend too much time watching TV or playing computer games. They stay up (熬夜) very late. Some students have to get up early every morning on weekdays to get to school n time by bus or by bike. It can be a long way from home to school.

　　Schools and parents should cut down some of the homework so that our children can enjoy more than nine hours of sleep every night for their health. For children, we should make best use of our time. When we have enough time for sleeping, we will find it much better for both our study and health.

A Brown University sleep researcher has some advice for people who run high schools: Don’t start classes so early in the morning. It may not be that the students who nod off at their desks are lazy. And it may not be that their parents have failed to enforce(确保) bedtime. Instead, it may be that biologically(生物学上)these sleepyhead(贪睡者)students aren’t used to the early hour.
　　“Maybe these kids are being asked to rise at the wrong time for their bodies,” says Mary Carskadon, a professor looking at problem of adolescent (青春期的)sleep at Brown’s School of Medicine.
　　Carskadon is trying to understand more about the effects of early school time in adolescents. And, at a more basic level, she and her team are trying to learn more about how the biological changes of adolescence affect sleep needs and patterns(方式).
　　Carskadon says her work suggests that adolescents may need more sleep than they did at childhood, no less, as commonly thought.
　　Sleep patterns change during adolescence, as any parent of an adolescent can prove. Most adolescents prefer to stay up later at night and sleep later in the morning. But it’s not just a matter of choice---their bodies are going through a change of sleep patterns.
　　All of this makes the transfer(迁移)from middle school to high school---which may start one hour earlier in the morning----all the more difficult, Carskadon says. With their increased need for sleep and their biological clocks set on the “sleep late, rise late” pattern, adolescents are up against difficulties when they try to be up by 5 or 6 a.m. for a 7:30 a.m. first bell. A short sleep on a desktop may be their body’s way of saying. “I need a timeout.”
