Question

It was _____ back home after the experiment.

It was _____ back home after the experiment.
A. not until midnight did he go
B. until midnight that he didn't go
C. not until mid night that he went
D. until midnight when he didn't go
A or C? Why?
为什么答案是C?是强调句不用倒装？

Answer 1

选C。
这是强调句型，基本结构是“It is/was......that......”。 本句被强调的部分是not until midnight，其后应该用that。
如果不用强调结构，本句可表达为：
Not until midnight did he go back home after the experiment.
希望能帮到您。

Answer 2

看错,是C。是滴，强调句不用倒装。
It was not until mid night that he went back home after the experiment.
Not until midnight did he go back home after the experiment.

He did not realize his fault until he failed
It was not until he failed that he realized his fault
Not until he failed, did he realize his fault.
