Astronauts, people who fly into space, need special training. First they go to Houston, Texas. That is the home of the Johnson Space Centre. There they are tested to see how strong and smart they are.
One of the first tests is for the heart. The people walk or run, then the space doctors see how fast their hearts are beating.
Another important test is performed. In this test the person must curl（蜷曲）his body up in a ball. When he is in that position, he is put into a round cloth bag. The doctors give him no idea how long he will have to stay in the bag. If a spaceship broke down in space, the astronauts would get into bags like this. Then they would have to wait and curl up in darkness, until help could arrive. You can see that an astronaut must not be afraid of tight space or darkness.
After the tests, only the best people are chosen to start astronaut training in a training centre. The astronauts in training learn many other things. They learn how to jump out of a moving airplane. They learn to how to blow up a lifeboat and get into it while they are in the ocean. The astronauts also have to learn how to get lifted out of the ocean by helicopter（直升机）. That may look fun, but it can be dangerous.
After they finish training, the astronauts continue to work. They stay in good shape by running and doing exercise. They read about their special jobs. In that way they can learn new facts about space travel.
Then the big day comes. The astronaut is told to go to work on a flight into space. The crew members（全体船员）get to know each other first. Then they can learn which job each will do.

A
Sam and Joe were astronauts. There was once a very dangerous trip and the more experienced astronauts knew there was only a small chance of coming back alive. Sam and Joe, however, thought it would be exciting though a little dangerous. “We’re the best men for the job,” they said to the boss. “There may be problems, but we can find the answers.” “They’re the last people I’d trust,” thought the boss. “But all the other astronauts have refused to go.”
Once they were in space, Joe had to go outside to make some repairs. When the repairs were done, he tried to get back inside the spaceship. But the door was locked. He knocked but there was no answer. He knocked again, louder this time, and again no answer came. Then he hit the door as hard as he could and finally a voice said, “Who’s there?” “It’s me! Who else could it be?” shouted Joe. Sam let him in all right but you can imagine that Joe never asked to go on a trip with Sam again!
