　　The oddness of life in space never quite goes away. Here are some examples.

　　First consider something as simple as sleep. Its position presents its own challenges. The main question is whether you want your arms inside or outside the sleeping bag. If you leave your arms out, they float free in zero gravity, often giving a sleeping astronaut the look of a funny balled(芭蕾)dancer. “I'm an inside guy，” Mike Hopkins says, who returned from a six-month tour on the International Space Station. “I like to be wrapped up.”

　　On the station, the ordinary becomes strange. The exercise bike for the American astronauts has no handlebars. It also has no seat. With no gravity, it's just as easy to pedal violently. You can watch a movie while you pedal by floating a microcomputer anywhere you want. But station residents have to be careful about staying in one place too long. Without gravity to help circulate air, the carbon dioxide you exhale(呼气) has a tendency to form an invisible(隐形的)cloud around you head. You can end up with what astronauts call a carbon-dioxide headache.

　　Leroy Chiao, 54, an American retired astronaut after four flights, describes what happens even before you float out of your seat，“Your inner ear thinks you're falling. Meanwhile your eyes are telling you you're standing straight. That can be annoying—that's why some people feel sick.” Within a couple days—truly terrible days for some—astronauts' brains learn to ignore the panicky signals from the inner ear, and space sickness disappears.

　　Space travel can be so delightful but at the same time invisibly dangerous. For instance, astronauts lose bone mass. That's why exercise is considered so vital that National Aeronautics and Space Administration(NASA) puts it right on the workday schedule. The focus on fitness is as much about science and the future as it is about keeping any individual astronauts return home, and, more importantly, how to maintain strength and fitness for the two and a half years or more that it would take to make a round-trip to Mars.

　　【语篇解读】　这是一篇说明文。本文通过举例说明了太空生活的奇妙：在太空睡觉时，对宇航员来说主要的挑战在于恰当的睡眠姿势，最后告诉我们美国国家宇航局对宇航员主要的担心是宇航员回家后的修养期和如何在太空长久地保持健康。

　　4.What is the major challenge to astronauts when they sleep in space?

　　A. Deciding on a proper sleep position

　　B. Choosing a comfortable sleeping bag

　　C. Seeking a way to fall asleep quickly

　　D. Finding a right time to go to sleep.

　　答案与解析：A　细节理解题。根据第二段第一、二句“First consider something as simple as sleep. Its position presents its own challenges.”可知在太空睡觉时，对宇航员来说主要的挑战在于恰当的睡眠姿势。故选A项。

　　5.The astronauts will suffer from a carbon­dioxide headache when ________.

　　A. they circle around on their bikes

　　B. they use microcomputers without a stop

　　C. they exercise in one place for a long time

　　D. they watch a movie while pedaling

　　答案与解析：C　细节理解题。根据第三段中“But station residents have to be careful about staying in one place too long. ...You can end up with what astronauts call a carbon­dioxide headache”可知宇航员在一个地方运动久了会出现碳毒性头痛。故选C项。

　　6.Some astronauts feel sick on the station during the first few days because ________.

　　A. their senses stop working

　　B. they have to stand up straight

　　C. they float out of their seats unexpectedly

　　D. whether they are able to go back to the station

　　答案与解析：D　细节理解题。根据第四段中“Your inner ear thinks you're failing. Meanwhile your eyes are telling you you're standing straight. That can be annoying—that's why some people feel sick.”可知宇航员在大脑接收到矛盾的信息时会感到恶心。故选D项。

　　7.One of the NASA's major concerns about astronauts is ________.

　　A. how much exercise they do on the station

　　B. how they can remain healthy for long in space

　　C. whether they can recover after returning home

　　D. whether they are able to go back to the station

　　答案与解析：B　细节理解题。根据最后一段倒数第一、二句“The focus on fitness is as much about science and the future as it is about keeping any individual astronaut healthy...NASA is worried about two things：...and, more importantly, how to maintain strength and fitness...”可知美国国家宇航局对宇航员主要的担心之一是如何在太空长久地保持健康。故选B项。

　　Ⅵ.短文改错

　　Recently I do a survey among the Senior 1 student in our school on sports training after school.

　　The survey shows that only 35% of the students do sports in their spare times. There are many reasons for this. Half of the students say they have too many homework and have not enough time to taking exercise. 30% of them complain that they have no places what they can relax themselves and that there are not enough training facilities. 10% of their feel that they live too far away from the places, that makes it difficult for them take exercise, and some even don't know how to take exercise.

　　Many students are in a poor health because they don't take enough exercise. We should realise the importance of taking exercise and do something to improve the present situation.
