Light gets Light, and this is essential for plants to make the food which we eat. Heat ,too, makes our environment【S2】______. Various kinds of rays come through the air from outer space ,but enormous【S3】______of radiation from the sun are【S4】______off. As soon as men leave the atmosphere they are【S5】______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 danger to explorers in space. The unit of radiation is called "rem". Scientists have reason to think that a man can【S6】______up with far more radiation than 0.1 rem without being damaged; the figure of 60 rems has been【S7】______on. The trouble is that it is extremely difficult to be sure about radiation damage -- a person may feel perfectly well ,hut the cells of his or her sex organs may he damaged, and this will not be discovered until the birth of【S8】______children or even grandchildren.【S9】______of the Apollo flights have had to cross belts of high amount of rems. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to【S10】______the damage done by radiation, but no really effective ones have been found so far.

选项
答案
H
解析
) deform 意为“扭曲,变形”,deformed指“不成形的,丑陋的,残废的”。在原文中的语境是:一个人是否受到辐射的伤害是很难判断的,只有受害者生了畸形婴儿或孙儿有残疾时才能证明这一点。deformed一词常用来修饰人,表示身体不健全。
