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.

选项
答案

解析
