8、uits or the walls of their spacecraft(他们的宇航服和宇宙飞船的外壳)，宾语是a lot of radiation damage(许多辐射危害)，二者之间的逻辑关系应该是“宇航服或宇宙飞船的外壳可以防止辐射危害”，因此E为正确答案。5.答案: B。解析 此处应填名词。所填词作介词in的宾语。根据前半句话的意思可以判断，B选项符合句意。in space意为“在太空中”。6.答案: F。解析 此处应填名词。该句意为辐射的量是以“雷姆”为单位计量的，因此F为正确答案。7.答案: K。解析 此处应填副词。根据该句破折号后的内容“一个人可能感觉一点问题没有，但他/她的
