答案： 1.B [解析]由设空后的 astronauts wouldn't be able to leave their spaceship可知，没有宇航服，宇航员将不能离开宇宙飞船。由此可推知，宇航服是特别的。故选B。
2.B
3.D [解析]由下文“Firstly，there is no air to breathe. Secondly... Thirdly...”可知，本段讲述了太空的三个危险因素，因此对于人类来说太空是危险的地方。dangerous意为“危险的”，符合语境。故选D。
4.A [解析]由上文 space also has high levels of radiation可知，太空存在很强的辐射，可推断这种辐射会让人生病。sick意为“生病的”，符合语境。故选A。
5.D
6.C [解析]句意：因此，如果宇航员不穿宇航服到宇宙飞船外面，他们就可能在几秒内死亡。step意为“迈步”，符合句意。故选C。
7.A
8.C [解析]由设空后的 harmful radiation and fast - moving space dust可知，此处用protect（保护）。故选C。
9.B [解析]above意为“在……之上”；under意为“在……之下”；behind意为“在……之后”；between意为“在……之间”。根据文章可知宇航服不只一层；根据逻辑推断像睡衣的一层应该在下面。故选B。
10.C [解析]由设空后的 because wearing spacesuits can make astronauts very hot可知，穿宇航服会让宇航员很热，由此可推知，水流经这些管子能让宇航员感到凉快。cool off意为“冷却”，符合语境。故选C。
