Every morning you get up，wash your face，brush your teeth，eat breakfast and get ready for your day.The daily actions are so common that you don't think about them much.But what if you were in space？
    When astronauts are in space，they eat，sleep，wash，work and play.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 moves slowly in the air，and astronauts must eat and drink carefully.They have special plates so that their food doesn't float away.They use special bags for drinks so that the drink stays inside.
    Sleeping is very difficult in space.Some astronauts like to move in the air，but most like to be in a sleeping bag.They tie the bags to a wall so that they don't fly in the air at night. The sun rises and sets so often that the astronauts use a clock or music to wake them up.
    Exercise is very important in space.On Earth，your legs carry your body，but in space，astronauts fly in the air，so they do not use their legs.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 on radio.The most popular pastime is looking out of the window，looking at the space and watching the earth.
