2016考研英语作文必背高分句：宇宙云

The existence of the giant clouds was virtuallyrequired for the Big Bang, first put forward in the1920s, to maintain its reign as the dominantexplanation of the cosmos.

译文：

巨大的宇宙云的存在，实际上是使20世纪20年代首次提出的大爆炸论得以保持其宇宙起源论的主导地位所不可缺少的。

点睛：

该句的主干是The existence...was...required...。first put forward in the 1920s是插入语，用于修饰限定之前的the Big Bang，其中put forward和the Big Bang之间是被动关系。介词短语as...是reign的补足语。
