Living on a space station is a lot like living on the Earth; astronauts eat, sleep, work, exercise, and play. Don't get too excited,
astronauts also attend meetings and do chores (杂务)！ Astronauts must do everything according to a strict schedule.
1. What do astronauts eat in space？
In the past, space food was freeze-dried (冷冻干燥), powdered (粉末状的), and very small in size. Today's astronauts eat the same food people eat on the Earth. Now scientists have developed special
packaging (包装). With it, food can be kept for as long as a year and still taste good!But the favorite space food among American astronauts is still shrimp cocktail (冷盘虾).
2. How do astronauts eat in space？
Astronauts use foot and leg holds (固定物) to eat at tables. They also use magnets (磁铁) to hold knives, forks, spoons, and scissors to food trays (托盘). When they want a drink, they use special straws (吸管) so that liquid will not come out and fly everywhere around.
3. How do astronauts wash and keep clean？
Each astronaut has a personal hygiene kit (个人卫生箱). He can stick it to a wall. Besides brushing their teeth, astronauts seldom use water for personal hygiene. For example,
they wash their hair with a rinse-free (免冲洗的) shampoo. Plus, the toilets don't use water to remove waste — it's all done with air！
4. How do astronauts sleep？
Astronauts sleep inside sleeping bags in bunk beds (双层床), but they have to use seat belts! There are only four bunk beds in the space shuttle (航天飞机), so some of them have to sleep in their seats. Each morning a different astronaut chooses a different song for playing
to wake up the other astronauts.
