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.

选项
答案
M
解析
空格处填入ones的限定语,可为形容词或分词。句中ones指代前面出现的drugs,空格所在句说的是治疗辐射造成的损伤的药物还没有找到,备选项中curable“能治愈的”修饰的对象是疾病而不是药物,故排除。effective“有效的”,通常指能取得预期或先见效果的,符合句意。
