Ⅴ. 阅读理解(10分)
Can you imagine astronauts’ everyday life in space? They also need to eat, sleep, exercise and relax. They do the same things as us, but they do them differently.
On the Earth, we put food on a plate. Gravity holds the food down and keeps it on a place. But there is almost no gravity in space, so food can float(飘; 飘浮)away, and astronauts must eat carefully.
　　Sleeping is very different in space. Some astronauts like to float in the air, but most like to be in a sleeping bag. They tie(系; 系住)the bag to a wall so that they won’t float away at night.
Exercise is very important in space. On the Earth, your legs carry your body, but in space, astronauts float, so they do not use their legs often. This is very bad for their legs, so they must exercise for thirty minutes every day.
After a day’s work, astronauts relax. They may listen to music, read, watch films, play games, or talk to their friends and families on the radio. Sometimes they just enjoy floating in the air.
1. Astronauts tie the sleeping bag to a wall because________.
A. in that way they won’t float away
B. that makes them sleep well
C. they can’t get to sleep if they don’t do that
D. the sleeping bag is not safe enough
【解析】选A。细节理解题。由第三段第三句话“They tie the bag to a wall so that they won’t float away at night. ”可知, 宇航员把睡袋系在墙上, 这样晚上就不会飘走。故选A。
2. Astronauts must exercise________every day when they are in space.
A. more than an hour　　　 B. half an hour
C. 13 minutes　　　　　　 D. nearly an hour
【解析】选B。细节理解题。由第四段第三句话“. . . so they must exercise for thirty minutes every day. ”可知, 宇航员在太空中必须每天锻炼30分钟, 即半小时。故选B。
3. Astronauts can’t________in space according to the passage.
A. listen to music　
B. talk to their friends and families
C. play games　
D. run as they are on the earth
【解析】选D。推理判断题。由第四段第二句可知, 在太空中, 宇航员不能像我们一样行动, 所以他们不会像在地球上一样奔跑。故选D。
4. The main idea of the passage is about________.
A. the importance of gravity
B. astronauts’ everyday life in space
C. the differences between space and Earth
D. how to avoid(避免)floating away while sleeping
【解析】选B。主旨大意题。本文从吃饭、睡眠、锻炼和休闲四方面介绍了宇航员在太空中的生活。故选B。
