Question

【题目】Another thing an astronaut has to learn about is eating in space．Food is weightless, just as men are.

Food for space has to be packed in special ways．Some of it goes into tubes that a man can squeeze into his mouth．Bite-sized cookies are packed in plastic.

There is a good reason for covering each bite．The plastic keeps pieces of food from traveling in the spaceship．On the earth very small pieces of food would simply fall to the floor．But gravity doesn’t pull them to the floor when they are out of the plastic in a spaceship．They move here and there and can get into a man’s eyes or into the spaceship’s instruments．If any of the instruments is blocked, the astronauts may have trouble getting safely home.

As astronauts travel on longer space trips, they must take time to sleep．An astronaut can fit himself to his seat with a kind of seat belt. Or, if he wants to, he can sleep in a sleeping bag which is fixed in place under his seat．But be careful he must put his hands under the belt when he goes to sleep．This is because he is really afraid that he might touch one of controls that isn’t supposed to be touched until later.

【1】Why would astronauts cover each bite of food in space?

A. Because small pieces of food would fall down to the floor.

B. Because weightless pieces of food might make trouble when they travel around．

【2】In a spaceship, astronauts can ________.

A. walk just as they do on the earth

B. not eat anything because it’s dangerous

C. control the spaceship when they are sleeping

D. not litter small things or it will make trouble

【3】Why does an astronaut put his hand under his belt when he sleeps?

A. Because he thinks it is comfortable to sleep in that way in space.

B. Because he doesn’t want to touch any controls when he sleeps.

C. Because the instruments of the spaceship are easily broken.

D. Because he is afraid that the seat will move.

【解析】文章介绍在太空失重的情况下宇航员怎么吃东西及睡觉，也解释了这样做的原因。

【1】B 细节理解题。根据第三段中But gravity doesn’t pull them to the floor when they are out of the plastic in a spaceship．They move here and there and can get into a man’s eyes or into the spaceship’s instruments．可知，食物的碎片可能在他们飞行的时候带来麻烦，故选B。

【2】D 细节理解题。根据第三段中If any of the instruments is blocked, the astronauts may have trouble getting safely home.可知，在飞行中，宇航员不能扔垃圾，否则会有麻烦。故选D。

【3】B 细节理解题。根据最后一段中But be careful he must put his hands under the belt when he goes to sleep．This is because he is really afraid that he might touch one of controls that isn’t supposed to be touched until later．可知，宇航员要把手放在安全带的下面，防止它碰到设备。故选B。

【4】A 主旨大意题。文章前面三段讲的是宇航员在太空的饮食问题，第四段讲的是宇航员怎么睡觉。故选A。
