Question

一道奇怪的英语题.
The fact that ____ was discovered in 1923 by the astronomer Edwin Hubble.
A) the expansion of the universe
B) the universe is expanding
C) the universe,which is expanding
D) when the universe expands
真是不可思议啊!答案竟然是B.THAT后面引导的那个从句不是已经有了个WAS了吗?如果选B,那岂不是又做个谓语动词IS?同一个句子怎么可能出现两个谓语BE动词
哪个专家告诉我到底是怎么回事?顺便说说这是一个什么从句?

Answer 1

选B没错.that引导同位语从句,修饰先行词fact.先把同位语放在一边不看,整个句子就是the fact was discovered in 1923 by the astronomer Edwin Hubble. 那么,是什么样的事实呢?就是the universe is expanding 这个事实.
