    外研版高中英语选修8 Module 5《The Conquest of the Universe》ppt课件
    It is interesting how NASA chose their astronauts for landing on the moon.They chose men between the age of twenty and thirty-five.There were about fifty of them.Many were experienced air pilots.Others were scientists with two or three degrees.NASA telephoned each man they were going to choose and told him the dangers he might get in.They then asked him if he was willing to be trained as an astronaut.“How could any man refuse such an exciting job?” The health and physical conditions of pilots were,of course,very necessary.Only those in very good health and physical condition were chosen. While being trained to be astronauts,they went through many courses.They studied the star and the moon,and they also studied geology,the science of rocks.This was necessary because astronauts would have to look for rocks on the moon.They would try to find rocks which might help to tell the age of the moon.They were all trained to fly in helicopters.These helicopters landed directly down to give them some experience of the way the spaceship would really land on the moon. They were also taught the unknown facts about the conditions in space.They learnt all the technical details of the spaceships and rockets.They visited the scientists and engineers who designed the spaceships and rockets.They visited the factories where the spaceships and rockets were built.They learnt how every part of a spaceship and its instruments work.They also learnt every detail of the ground-control system. 7C中小学课件http://cai.jmverville.com 课堂讲练互动 The Conquest of the Universe Module 5 背 景 e 站 链 接 In a word,to be chosen as an astronaut,one must be in good health,well-informed in science and good at piloting.
