Satellites are an important part of our ordinary lives．For example, the information for weather forecasts is sent by satellite．Some satellites have cameras which take photographs of the Earth to show how clouds are moving．Satellites are also used to connect our international phone calls．

Computer connections of the World Wide Web and Internet also use satellites. Many of our TV programs come to US through satellites．Airplane pilots also sometimes use a satellite to help them find their exact location．

We use satellites to send television pictures from one part of the world to another．They are usually 35，880 kilometers above the equator．Sometimes we can see a satellite in the sky and it seems to stay in the same place．This is because it is moving around the world at 11，000 kilometers an hour—exactly the same speed that the earth rotates．A satellite must orbit the Earth with its antennae(天线)facing the earth．Sometimes, it moves away from its orbit(轨道)，So there are little rockets on it which are used to put the satellite back in the right position．This usually happens about every five or six days．

Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth．A satellite usually works for about 10-12 years．Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to Earth to be repaired．Often，very old or broken satellites are left in space to orbit the Earth for a very long time．This is very serious because some satellites use nuclear（核） power and they can crash into each other．

1.Which of the following is NOT done by satellites according to the passage?

A．Sending information for weather forecast．

B．Taking photographs of the Earth．

C．Sending TV pictures．

D．Providing food for airplane pilots．

A．35,880 kilometers per hour．

B．335,880 kilometers per hour．

C．11,000 kilometers per hour．

D．110,000 kilometers per hour

3.Why does the satellite move around the world at the same speed as the Earth rotates?

A．In order to take photographs．

B．In order to stay in a certain position in the orbit．

C．In order to move away from its orbit．

D．In order to send television pictures．

4.What does the underlined word “This” in the 3rd paragraph refer to?

A．A satellite．

B．A little rocket．

C．A satellite seems to stay in the same place in the sky．

D．The satellite puts the rockets in the right position．

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(瞌睡虫)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.”

_______.

A. it is really tough for parents to enforce bedtime

B. it is biologically difficult for students to rise early

C. students work so late at night that they can’t get up early

D. students are so lazy that they don’t like to go to school early

2.The underlined phrase nod off most probably means _______.

A. turn aroundB. agree with othersC. fall asleepD. refuse to work

3.What might be a reason for the hard transfer from middle school to high school?

A. Adolescents depend more on their parents.

B. Adolescents have to choose their sleep patterns.

C. Adolescents sleep better than they did at childhood.

D. Adolescents need more sleep than they used to.

4.What is the passage mainly about?

A. Adolescent health care.

B. Problems in adolescent learning.

C. Adolescent sleep difficulties.

D. Changes in adolescent sleep needs and patterns.
