Eating in space is different from
eating on the earth. The food that astronauts (宇航员) carry with them does not
look like the food we eat. Some food is carried in closed bags.
It is cooked and frozen (使结冰,冻结) before the astronauts get it. All the water is
removed (去掉) from the food. In the space capsule (座舱), the astronaut puts the
water back. He "shoots" hot or cold (寒冷的,伤风) water into the food bag with a
special gun (枪,炮). He eats the food through a small hole in the bag.
Other foods come in bite (咬,刺骨) sizes. The astronaut puts a whole (全部,完整的)
piece in his month at once. There can be no crumbs (碎屑). Crumbs would float
