问题 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 (飘浮,浮游物) around the capsule (胶囊,小盒) and get in the way. Meat, cake, and cereal (谷类食物) often come in bite-sized pieces.
Astronauts cannot drink water from open cups. The water would float in drops in the air. The water is put in the special gun. The astronaut shoots the water into his mouth.
Eating in space is not easy.  Astronauts must learn to eat this way.
选项 A、The water would float in drops in the air.
B、The water would be frozen in open cups.
C、Crumbs and cereal would float in the cups.
答案A
解析 答案就在最后一段第二句。
