  It is interesting how NASA chose their astronauts for landing them on the moon.They chose me¡¡1¡¡the age of twenty and thirtyª²five. There were about fifty of them.Many were¡¡2¡¡air pilots.¡¡3¡¡were scientists with two or three deGREes.NASA telephoned each man they were going to choose,told him the plans and the¡¡4¡¡they might get in.They then asked him if he was willing to be trained as an astronaut.¡°How could any man¡¡5¡¡such an exciting job? one of them said.¡±Dangerous? Of course.It's dangerous¡¡6¡¡most exciting,¡°

     The health and physical condition of¡¡7¡¡was,of course,very necessary.¡¡8¡¡those in very good health and physical condition were chosen.

     While being trained to be astronauts,they went through many ¡¡9¡¡.They studied the stars and the moon,and they also studied geology,the science of rocks.This was necessary¡¡10  ¡¡astronauts would have to look for rocks on the moon.They would try to find rocks which might help to tell the¡¡11¡¡of the moon.They were all¡¡12¡¡to fly in helicopters. These helicopters landed¡¡13¡¡down to give them some experience of the way the spaceship would¡¡14¡¡land on the moon.They were also taught the¡¡15¡¡facts about the conditions in space.They learnt all the technical details of the spaceships and rockets.They visited the scientists and engineers who¡¡16¡¡them. They visited the factories where they were¡¡17¡¡.They learnt how every
¡¡18¡¡of a spaceship and its instruments work.They also learnt every detail of a groundª²control ¡¡19¡¡.

     In a word,to be chosen as an astronaut,one must be in good health,¡¡20¡¡in science and good at piloting.
