关于not until的倒装和强调

D not until midnight that he went

It was not until midnight that he went back home after the experiment.

强调句式（It is/was that/who）

强调句式　的特点是

去掉It was …… that句子仍然成立

He went back home after the experiment not until midnight .

这句话强调的是时间状语，所以用强调句式，后面的句子顺序不变。

D not until midnight that he went

强调句型：It was/is 被强调部分 + who/that+....

对于not until 的强调句，要把not until中的 until后面的部分直接拿过来。

后面的句子不用倒装了。

如果是倒装句，那么后面用采用部分倒装了

Not until midnight did he go back home after the experiment.
