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 acts 【C1】_____ our protective blanket on earth. Light gets through, and this is 【C2】_____ for plants to make the food 【C3】_____ we eat. Heat, too, makes our environment endurable. Various kinds of rays 【C4】_____ the air from outer space, 【C5】_____ enormous quantities of radiation from the sun are 【C6】_____ off. As soon as men leave the atmosphere they are 【C7】_____to this radiation but their spacesuits or the walls of their spacecraft, 【C8】_____ they are inside, do prevent a lot of radiation damage.
Radiation is the greatest known 【C9】_____ to explorers in space. The unit of radiation is called "rem (雷姆)". Scientists have reason to think that a man can 【C10】_____ far more radiation 【C11】_____ 0.1 rem without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extremely 【C12】_____ to be sure about radiation damage—a person may feel perfectly well, but the 【C13】_____ of his or her sex organs may be damaged, and this will not be discovered 【C14】_____ the birth of deformed children or even grandchildren.

We simply do not know yet how men are going to get on when they 【C17】_____ weeks and months outside the 【C18】_____ of the atmosphere, working in a space laboratory.

选项
A、exploited
B、exhibited
C、exposed
D、employed
答案
C
解析
考查形近动词辨析及上下文语义逻辑。be exposed to意为“暴露于”,填入空中指人离开大气层以后就暴露于各种辐射中,符合语境,故选C。exploit“开采;剥削”,exhibit“陈列;展示”,employ“雇佣;使用”,均不符合此处语境。
