重点短语精学：

not... until

这个句型从形式上看是否定句，但并非否定意思。until也可单独使用，表示“直到……为止”。

医生直到房间里的灯足够亮了，才开始做手术。

Not until I began to work did I realize how much time I had wasted.
直到我开始工作，我才认识到了我已蹉跎了几多岁月。

当主句是否定句时，它引出的意思是"直到（某时）（某动作）才（发生）" ，这时候常会出现"not until …"的结构，如果将 "not until …"的结构放在句首，那么主句要写成倒装句。例如：

They didn't realize their fault utill we pointed it out to them.

直到我们向他们指出了他们的错误，他们才意识到。

Not until we pointed out their fault to them did they realize it.

直到我们向他们指出了他们的错误，他们才意识到。
