It is interesting how NASA(美国航天航空局) 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. Some were
37 air pilots, and
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 into. 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 the people was,
42 , very necessary. Only those in very good health and physical condition were
43 .
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 actually land on the
49 . They were also taught the known facts about the
50 in space. They learnt about all the scientists and engineers who
51 spaceships. They visited the
52 where spaceships were repaired. 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.
