Can you imagine astronauts' everyday life in space? They also need to eat,  sleep, exercise and relax. They do the same things as us, but they do them differently.

On Earth, we put food on a plate. Gravity holds the food down and keeps it on a place. But there is almost no gravity in space, so food can float （漂浮）away, and astronauts must eat carefully.

Sleeping is very different in space. Some astronauts like to float in the air, but most like to be in a sleeping bag. They tie the bag to a wall so that they won't float away at night.

Exercise is very important in space. On Earth,  your legs carry your body,  but in space, astronauts float, so they do not use their legs often. This is very bad for their legs, so they must exercise for thirty minutes every day.

After a day's work, astronauts relax. They may listen to music, read, watch films, play games, or talk to their friends and families on the radio. Sometimes they just enjoy floating in the air.

3.What's the main idea of the passage?

Jess really felt very happy. When he arrived at his seat in the classroom that morning, he found an invitation（请柬）on his desk. It was from some of his classmates asking him to join their camping trip. This was the first time he was asked to join in an out-of-school activity. Why were they asking him now? Nobody seemed（似乎）to like him. In fact, he had been so lonely (孤独) that he ate a lot to make himself feel less lonely. As a result, he had put on a lot of weight, and this gave the children something more to make fun of him.

Cindy, who was standing near Jess when he read the invitation, went out quickly to tell the others that the trick had worked. Everyone was happy that Jess thought that was true. But there was no camping trip. The whole thing was made up.

At first, Cindy thought it was fun. But later, when Jess told her that he was going to buy a sleeping bag with his pocket money, Cindy had a second idea. She knew that Jess’s family had little money, and she hated to see him spend his pocket money on something he would never use. Cindy also hated to tell Jess the truth (真相). Her close friends would be unhappy with her.

What could she do now?

1.What would happen if Cindy told Jess the truth?

4.Which is the best title for this passage?

Everyone has got two personalities（性格）the one that is shown to the world and the other that is secret and real. You don’t show your secret personality when you’re awake because you can control your behavior, but when you’re asleep, your sleeping position shows the real you. In a normal night, of course, people frequently change their positions. The important position is the one that you go to sleep in.

If you go to sleep on your back, you’re a very open person. You normally trust people and you are easily influenced by fashion or new ideas. You don’t like to displease people. So you never express your real feelings. You’re quite shy and you aren’t quite sure of yourself.

If you sleep on your stomach, you are a rather secretive person. You worry a lot and you’re always easily upset. You always stick to your own opinions or judgment, but you don’t raise your hopes too much. You usually live for today not tomorrow. This means that you enjoy having a good time.

If you sleep curled up（蜷缩）, you are probably a very nervous person. You have a low opinion of yourself and so you’re often defensive. You’re shy and you don’t normally like meeting people. You prefer to be on your own. You’re easily hurt.

If you sleep on your side, you have usually got a well—balanced personality. You know your strengths and weakness. You’re usually careful. You believe in yourself. You sometimes feel anxious, but you don’t often get sad. You always say what you think even if it makes people rather angry
