Lesson Eighteen

Fun Things about Living in Space

1.Do you know how astronauts live in space?

2.It's actually quite fun!

3.In a spacecraft, standing is as comfortable as lying down.

4.However, to sleep well, astronauts must get into sleeping bags attached to the walls.

5.Otherwise, they might drift somewhere else.

6.Moving around in a spacecraft also requires skills.

7.Unlike walking on the ground with legs and feet, in the cabin astronauts move mainly by using their arms.

8. In order to facilitate astronauts’ movement in the cabin, many special handrails are installed on the walls.

9.Normally, astronauts rely on these handrails or other equipment to balance their bodies.

10.In the spacecraft, astronauts cannot drink water with usual cups.

11.Because the water is in a weightless state, even if the cup is turned upside down, the water will not flow downward.

12.If the astronauts wants to drink water, they must use a drinking bag with a straw and squeeze the water directly into their mouths.

13.Bathing in space is not an easy task.

14.The water coming out of the shower head will always float in the air. In order to fix this problem, researchers conducted an experiment.

15.They designed a sealed bath tub and installed a straw suction tube underneath, which allowed the water coming out of the shower head to be sucked in one direction. 

16.But after a shower, the astronauts had to spend a long time cleaning up the water on their bodies and in the tub, which was too troublesome.

17.So now astronauts usually clean their bodies with disposable wipes only, which is much simpler and efficient.

18.See? Isn't it fun to live in space?

太空生活趣事多

1.你知道航天员在太空中怎样生活吗?

2.说起来还挺有趣呢!

3.在宇宙飞船里，站着睡觉和躺着睡觉一样舒服。

4.不过，要想睡个安稳觉，航天员必须钻入固定在舱壁上的睡袋里。

5.不然，一不小心就会飘到别处去。

6.在宇宙飞船里活动也需要技巧。

7.跟在地面上用腿脚行走不同，航天员在舱体里移动主要靠手臂。

8.为了方便航天员在舱体中活动，舱壁上安装了很多特制的扶手。

9.平时，航天员会依靠这些扶手或其他设施稳定自己的身体。

10.在宇宙飞船里，是没有办法用普通的杯子喝水的。

11.因为水处于失重状态，即使把杯子倒过来，水也不会往下流。

12.航天员要想喝到水，得使用一种带吸管的饮水袋，直接把水挤到嘴里。

13.航天员在太空中洗澡可不是一件容易的事。

14.从喷头喷出的水总是飘浮在空中，为了解决这个问题，科研人员做了一个试验。

15.他们设计了一个密封浴桶，在下边安装吸管，它可以把喷头喷出来的水朝一个方向吸。

16.但洗完澡以后，航天员还要花很长时间清理身体上和浴桶里的水，实在太麻烦了。

17.所以，现在航天员通常只用免洗湿巾擦拭身体，这就简单省事多了。

18.你看，在太空中生活，是不是很有趣?
