Do you want to be an astronaut in the future? Every year on April 24, it's Space Day of China. It's a day to celebrate China's \underline{36} in space exploration(探索). Ever since Yang Liwei made \underline{37} to space in 2003, about 20 Chinese astronauts have been to space.
In space, astronauts face many problems. There is \underline{38} gravity(重力). For example, the gravity on the moon is only $\frac{1}{6}$ of that on the earth. So their bodies become much lighter in space. \underline{39}, being away from family and friends for a long time can make them feel \underline{40}. What's more, if something goes wrong \underline{41}, they have to work fast and try to fix it by themselves. That's \underline{42} astronauts have to be smart, strong, and ready for any \underline{43} before they can go to space.
To make sure that Chinese astronauts finish their work and \underline{44} to Earth safely, eight kinds of training are set. Apart from(除了) physical training, astronauts also \underline{45} science knowledge and mock(模拟) training. Before they can go to space, they \underline{46} like this for at least three and a half years.
Among the training subjects, the \underline{47} part is the underwater training. It's difficult but helps astronauts \underline{48} the weightless environment in space. Astronauts need to wear diving suits(潜水服) that weigh more than 100 kilos and stay underwater for six hours at a time. Moving around in the water with such a \underline{49} suit is really tiring. One astronaut, Nie Haisheng, even lost 2 kilos \underline{50} one underwater training exercise.
