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)". Scientists have reason to think that a man can put up with far more radiation than 0.1 rem without being damaged. The trouble is that it is【C6】______ difficult to be sure about radiation damage—a person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will not be discovered【C7】______ the birth of deformed children or even grandchildren.
We simply do not know yet how men are going to get on when they spend weeks and months outside the【C8】______ of the atmosphere, working in a space laboratory. Drugs might help to【C9】______ the damage done by radiation, but no really【C10】______ ones have been found so far.
【C5】
选项
答案
L
解析
定冠词the提示此处填入名词。大多数辐射对人是有害的,由此可首先锁定disaster、danger;再联系下文的“……人可以忍受远大于0.1雷姆的辐射而不受到损伤(damaged)”,由此说明“辐射”是一种“可能造成损伤的事物”而非灾难性的事物,danger符合句意。
