河北2017.11成人学位英语考试通关试题及答案二
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 travelling 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 instru-ments is blocked, the astronauts may have trouble getting safely home.
As astronauts travel on longer space trips, he 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.
16.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.
C.Because they haven' t enough food for longer trips.
D.Because astronauts don' t want to waste food.
答案：B
解析：事实细节题。文章第二段主要是解释食物要用塑料包起来的原因。在太空中由于不存在重力，食物就会到处移动，可能飞到人眼睛里或宇宙飞船的仪器中，引起麻烦。
17.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
答案：D
解析：推理判断题。可以用排除法。在宇宙中，由于失重，宇航员不可能像在地球上一样行走，所以A不对。因为食物也像宇航员一样失重，吃东西就会变得非常困难，而不存在危险，所以B也不对。为了防止在睡眠中不小心触摸控制键，宇航员要将双手放在安全带下，因此他睡着的时候是不能控制宇宙飞船的，这样C也排除了。为了防止小东西由于失重飞到人眼睛里或机械中，宇航员是不能到处乱扔东西的，所以只有D是正确的。
18.In what way is food for space packed?
A.Very small pieces of food are put on the floor.
B.Some of it is put into tubes.
C.Small-sized cookies are packed in plastic.
D.Both B and C.
答案：D
解析：事实细节题。段的后两句指出，一些食物被放在管子里，小饼干则被用塑料包装起来。
19.Why does an astronaut put his hand under his belt when he ~leeps?
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.
答案：B
解析：事实细节题。文章后两句提到，为了防止在睡眠中不小心触摸控制键，宇航员要将双手放在安全带下。
20.The best title of this article is
A.Eating and Sleeping in Space
B.How Astronauts Eat in Space
C.Food for Space
D.How Astronauts Sleep in Space
答案：A
解析：归纳概括题。文章前两段讲的是太空中“吃”的问题，后一段讲的是太空中“睡”的问题，所以本篇文章的题目应是A“太空中的吃和睡”。B、C、D都只谈了一个方面，都是片面的。
