Can you imagine astronauts' everyday life in space? They also need to eat, sleep, exercise and relax. They do the same things as us, but they do them differently.
On Earth, we put food on a plate. Gravity holds the food down and keeps it on a place. But there is almost no gravity in space, so food can float （漂浮）away, and astronauts must eat carefully.
Sleeping is very different in space. Some astronauts like to float in the air, but most like to be in a sleeping bag. They tie the bag to a wall so that they won't float away at night.
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 often. This is very bad for their legs, so they must exercise for thirty minutes every day.
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 the radio. Sometimes they just enjoy floating in the air.
【小題1】What does the underlined word "gravity" mean in Chinese?
| A．平衡 | B．引力 | C．磁性 | D．重力 |
| A．Because in that way they won't float away. |
| B．Because that makes them sleep well. |
| C．Because they can't get to sleep if they don't do that. |
| D．Because the sleeping bag is not safe enough. |
| A．It is about the importance of gravity. |
| B．It is about astronauts' everyday life in space. |
| C．It is about the differences between space and Earth. |
| D．It is about how to avoid （避免） floating away while sleeping. |
