　　小题1:B小题1:D小题1:A小题1:A小题1:C 　　【主旨大意】文章介绍了宇航员们在太空当中也会面临着许多危险，其中主要是辐射和太空垃圾的威胁；辐射对宇航员们的伤害可能会在他们的第二代甚至第三代身上表现出来；太空垃圾中有一些是人造垃圾。太空垃圾对人们探测宇宙有很大的。小题1:B推理判断题由第三段中的句子“It’sreportedthattherewere9,000man-madethingsflyinginspace.About30%ofthesearesatellites,10%arespaceships,andtherestarespacerubbish.”可推断出选项B是正确答案；小题1:D细节理解题根据第二段的句子“Scientistshavefoundoutthattheradiation（辐射）isthegreatestdangertospacemeninspace.”可知道辐射是有害的，故选D；小题1:A词意猜测题根据下文中的smallpiece等可以看出该词意为“碎片”，故答案选A；小题1:A总结归纳题文章中共提到了两种太空威胁：一种是辐射；另一种是太空垃圾，故正确答案选A。小题1:C 推理判断题根据文中第一段中的句子“Theharmoftheradiationwon’tbefounduntiltheirchildrenevengrandchildrenareborn.”可得到正确答案为C。
