【解析】

本文是一篇说明文，主要介绍了宇航员在失重情况下的睡觉，锻炼和休闲方式信息。

1.句意：他们也需要吃饭，睡觉，锻炼和休息。

study学习；sleep睡觉；work工作；play玩。根据下文“Sleeping is very different in space.”太空睡觉是困难的。可知，是睡觉的意思。故选B。

2.句意：他们和我们做一样的事，但是他们和我们做的方式不同。

differently不同地；lovely可爱的；lonely孤独的；hardly几乎不。根据下文“On the earth, we put food on a plate and put ____3____ in a glass. Gravity (重力) holds the food down and keeps the water in the glass.”因为太空里没有重力。可知是不同地意思。故选A。

3.句意：在地球上，我们把食物放在盘子里，把水放在杯子里。

air空气；cloud云；water水；wind风。根据句意可知是把水放在杯子里。故选C。

4.句意：所以宇航员必须很小心地吃和喝。

because因为；but但是；so所以；if如果。根据上文“There is almost no gravity in space and food can fly away,”因为太空里没有重力，可知是表示所以的意思。故选C。

5.句意：但是大部分的人说喜欢在睡袋里。

when在……时候；if如果，是否；that那；why为什么。宾语从句中从句意思和成分完整，所以引导词用that。故选C。

6.句意：但是在太空，宇航员会漂浮。

but但是；so所以；or或者；because因为。根据上文“On the earth, your legs carry your body” 地球上，你的腿支撑着你的身体，但是在太空里不是。可知是转折关系。故选A。

7.句意：所以他们经常不用他们的腿。

they他们，主格；theirs他们的，名词性物主代词；them他们，宾格；their他们的，形容词性物主代词。后跟名词leg所以要用形容词性物主代词。故选D。

8.句意：这对他们的腿是很有害的。

of的；to到；for为了；with和，带。固定搭配be bad for对……有害。故选C。

9.句意：一天的工作之后，宇航员迫不及待要去休息了。

to relax休息；relaxing休息；to laugh笑；laughing笑。根据句意表示一天的工作之后，宇航员迫不及待要去休息了；固定搭配can’t wait to do sth.。故选A。

10.句意：他们可能听音乐，阅读，看电影，玩游戏，或花几分钟和朋友和家人在广播上交谈。

pay付钱；spend花费；take花费；cost花费。句子中they他们，人做主语，动词用了ing形式，所以要选择spend。固定搭配sb. spend some time doing sth.某人花时间做……。故选B。
