Question

It was not until yesterday ___me the truth为什么用A. did Janet tell。不用 B。Janet told

it was已经是强调啦 为什么还要用did,...为什么用told不行

Answer 1

not until 有三种用法结构，除了最基本的大家都会的基本结构，还有的就是强调结构和倒装结构
这道题考的就是强调B与倒装A
A选项是倒装即It was not until yesterday did Janet tell me the truth。
什么时候选B——中间加that构成it was not until + 从句+that+ 主句，即
It was not until yesterday that Janet told me the truth。

Answer 2

填that Janet told
