If you are dreaming of becoming an astronaut after you grow up, get started now! An astronaut needs a 1 body and mind. Astronauts are able to live upside-down (倒立). They do this not just during sleep, but also when eating and going to the toilet. Before they live in space, they have lots of 2 . Each upside-down training time 3 for 20 days.
Chinese astronauts aren't just spaceship drivers but also machine 4 and scientists. They have to know every 5 of the spaceship and how it works. If something goes wrong, they've got to know 6 to repair it. Also they do scientific experiments in space.
Astronauts took a knife, a gun and some dye (染色水) with them into space to keep safe when returning to the earth. If they land in 7 , the knife and the gun can protect them from wild animals. If they fall into the sea, the dye can color the seawater around them yellow. This can drive 8 sea animals away.
Astronauts must be in good health. They can't get a hurt or be 9 because they have to 10 many things. They've got no time for sickness.
