It is interesting how NASA(美国航空航天管理局)chose their astronauts for landing them on the moon. They chose men
26 the age of twenty and thirty-five. There were about fifty of them, Many were
27 air pilots.
28 were scientists with two or three degrees. NASA telephoned each man they were going to choose; told him the plans and the
29 they might get in. They then asked him if he was willing to be trained as an astronaut. “How could any man
30 such an exciting job?” One of them said, “Dangerous? Of course. It’s dangerous
31 most exciting”
The health and physical condition of
32 was, of course, very necessary.
33 those in very good health and physical condition were chosen.
While being trained to be astronauts. They went through many
34 . They studied the star and the moon, and they also studied geology, the science of rocks. This was necessary
35 astronauts would have to look for rocks on the moon. They would try to find rocks which might help to tell the
36 of the moon. They were all
37 to fly in helicopters （直升飞机）。These helicopters landed
38 down to give them some experience of the way the spaceship would
39 land on the moon , They were also taught the
40 facts about the conditions in space. They learnt all the technical details of the spaceships and rockets. They visited the scientists and engineers who
41 them. They visited the factories where they were
42. They learnt how every
43 of a space-ship and its instruments work. They also learnt every detail of ground-control
44 .In a word, to be chosen as an astronaut. One must be in good health,
45 in science and good at piloting.| 小题2: | | A．experienced | B．old | C．trained | D．young |
