当宇航员的困难英语作文

I believe that many little boys have a dream when they were

young, that is to be an astronaut, but we also know that being

an astronaut is a very difficult thing. Being an astronaut is

one of the most challenging jobs in the world because of the

unique working environment, the complexity of the job skills

and the enormity of the mission.

In the past, NASA, which is considered the most

authoritative agency in the world, has had its share of tragic

space tragedies. In 1986, a fuel leak on the space shuttle

Challenger killed seven astronauts when it exploded 73 seconds

after liftoff. So, to be an astronaut, you have to be prepared

to die at any time.

Chinese astronauts are also required to have a degree in

science and engineering, with candidates also required to have

more than 1,500 hours of jet flight experience and complete a

rigorous medical examination. These are just the first steps

in selecting a resume, followed by qualification screening,

clinical medical examination, physiological function

selection, psychological function selection, and special work

environment tolerance selection.

Those who pass these tests are only qualified to become astronauts. After becoming a preliminary astronaut, they have

to train for about four years as a professional astronaut. In

this process, once fail, will be eliminated at any time.

Astronaut is indeed the most challenging career in the

world, in addition to very good congenital conditions, to

complete a training, but also in every space mission can not

return to the earth, it can be said that each time when the

liftoff, the astronauts to the earth look back, hidden a special

farewell.
