When astronauts are in space, they eat, sleep, wash, work and play. 3 They do the same things as us, but they do them differently. 

On Earth, we put food on a plate and water in a glass. Gravity (引力) holds the food down and keeps the water in the glass. But in space, there is almost no gravity. So food can float(漂浮) away, and astronauts must eat and drink carefully.

Sleeping is very difficult in space. Some astronauts like to float in the air, but most like to be in a sleeping bag. They tie（拴）the flag to a wall so that they don’t float away in the night.

Washing is difficult. There is no shower or bath, so astronauts must use a sponge(海绵), They brush their teeth normally: they don’t want wet toothpaste to float around the spacecraft! 

Exercise is very important in space. On Earth, your legs carry your body, but in space, astronauts float, so they do not use their legs. 4 This is very bad for their legs, so they must exercise for thirty minutes every day. They often use an exercise bicycle for this.

After a day’s work, astronauts relax. They may listen to music, read, watch films, play games, or talk to their friends and families by radio. On the International Space Station, astronauts sometimes race from one end of the station to the other. The most popular pastime is looking out of the window, looking at the space and watching the Earth.
