资源描述

1有趣的太空生活在无边无际的太空里,几乎没有空气。人在那里无法呼吸,就好像沉到水里一样。所以,宇航员要穿上宇航服,用来保护自己。一件宇航服有 50 多千克重,里外有十多层,装着控制氧气、水、温度和压力的自动设备。宇航服虽然很笨重,但这点分量在太空中实在算不了什么。宇航员在宇宙飞船中可以不穿宇航服,但他们走路、睡觉、吃饭、洗澡以及大小便等都和我们在地面上的方式是不一样的。在太空中,宇航员几乎没有重量,只要轻轻一蹬脚,就能从这边“飞”到那边。字航员吃的东西像糨糊一样,装在像牙膏管子的容器里,挤进嘴里去吃,不让食物到处乱飞。洗澡要在密封的棚里,因为水不会往下流动,要用真空泵把脏水排掉。大小便时要把脚和腰绑住,否则人会飞起来。为了防止泡沫乱飞,宇航员用可以吃下去的牙膏刷牙。太空生活是多么的奇妙、有趣啊!快点学习科学知识吧,长大也当一名宇航员,驾着飞船去探索宇宙的奥秘!【导读】你想过上太空去生活吗?宇航员穿着宇航服在太空中过着像飞一样的生活。文章向我们介绍了宇航员走路、吃饭、洗澡以及大小便与在地球上是截然不同的。这一切多么奇妙有趣呀!课文太空生活趣事多 ,从内容上与本文相似,本文又补充了课文以外的有关太空中宇航员生活的情况,你感兴趣吗?2
