Space is a dangerous place, not only because of meteors(流星)but also because of rays from the sun and other stars. The atmosphere again【C1】______ our protective blanket on earth. Light gets through, and this is【C2】______ for plants to make the food we eat. Heat, too, makes our environment【C3】______. Various kinds of rays come through the air from outer space, but enormous quantities of radiation from the sun are screened off. As soon as men leave the atmosphere they are【C4】______ to this radiation but their spacesuits or the walls of their spacecraft, if they are inside, do prevent a lot of radiation damage.
Radiation is the greatest known【C5】______ to explorers in space. The unit of radiation is called "rem (雷姆)".

选项
答案
C
解析
根据下文“但如果他们穿着宇航服或待在太空船里,就能避免大量辐射造成的损伤”可知,前面说的是离开大气层就会受到辐射。备选项中exposed可与介词to搭配,构成be exposed to“暴露于”,符合语意。attributed虽然也可与to搭配,但填入句中语义不通,故不选。
