It is interesting how NASA(美国航天航空管理局) chose their astronauts for landing them on the moon. They chose men  36   the ages of twenty and thirty-five. There were about fifty of them. Many were  37   air pilots.  38   were scientists with two or three degrees. NASA telephoned each man they were going to choose, told him the plans and the  39   they might get in. They then asked him if he was willing to be trained as an astronaut, “How could any man  40   such an exciting job?” One of them said, “Dangerous? Of course. It’s dangerous  41   most exciting.”

The health and physical condition of  42   was, of course, very necessary.  43   those in very good health and physical condition were chosen.

While being trained to be astronauts, they went through many  44  . They studied the star and the moon, and they also studied geology, the science of rocks. This was necessary  45   astronauts would have to look for rocks on the moon. They would try to find rocks which might help to tell the  46   of the moon. They were all  47   to fly in helicopters. There helicopters landed straight down to give them some  48   of the way the spaceship would  49   land on the moon. They were also taught the  50   facts about the conditions in space. They learnt about all the scientists and engineers who  51   them. They visited the factories where they were  52  . They learnt how every  53   of a spaceship and its instruments work. They also learnt every detail of ground-control  54  .

In a word, to be chosen as astronaut, one must be in good  55  , well-informed in science and good at piloting.
