Question

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 midnight that he went
D. until midnight when he didn’t go

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

答案C
此题考查的是not…until句型的强调结构，其最根本结构是：He did not go back home after the experiment.①,把①转变为Not until midnight did he go back home after the experiment.②,注意②中的倒装结构，把②中划线部分放在强调结构It be 被强调部分that…中进行强调，但注意that从句后面不用倒装形式。
