This mission marked another step for China’s pursuit of moon exploration. In fact, people all over the world have been and are【C2】______developing technologies for the exploration of deep space and the peaceful use of outer space, as space is actually a dangerous place, not only because of meteors (流 星) but also because of rays from the sun and other stars.

选项
A、earth
B、atmosphere
C、space
D、environment
答案
C
解析
句意理解。本句意为射线是探险者在太空遇见的已知的最大危险。由句中核心词汇radiation和explorers可推测,该空应填space。其他选项从搭配和语意上来说都不符合要求。
