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、across
B、to
C、from
D、through
答案
D
解析
词汇辨析。本句意思是说各类来自外部空间的宇宙射线穿透大气层,故选介词through符合该句要求。这里的come through相当于penetrate(穿透)。come across意为“偶遇”,come to意为“来到”,come from意为“来自”,均不符合语意逻辑关系。
