Astronauts need special training. First they go to Houston，Texas，the home of the Johnson Space Center. There they 1       to see how strong and smart they are.

One of the first tests is for the heart. The people walk or run. Next the space doctors see how fast their hearts 2       Then another important test is ready. In this test the person must curl(蟲(chóng)卷曲)his body up in a ball. When he is in that position, he 3       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 4       bags like these. Then they would have to wait，curled up in darkness， 5      help could arrive.

6       the tests，only the best people are chosen to start astronaut training in the training center. There they learn many other things. They learn 7       to jump out of a moving airplane. They learn to blow up a lifeboat and get into it while they are in the ocean. The astronauts also learn how to get lifted (得救)out of the ocean by a helicopter (直升機(jī)).That may look like fun, hut it can be8      

After they finish 9       ，  the astronauts continue to work. They stay in good shape 10      running and doing exercise. They read about their special jobs. 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 (機(jī)組人員)members get to know each other first. Then they learn which jobs each will do.
