请详细分析一下这句话的句型?

Not until the child fell asleep did the mother leave the room.

你好。这属于not until 倒装句型的用法
意思翻译为:直到孩子睡了,妈妈才离开房间。
不会的,再看看下面的例子。希望对你有用。
1.当Not until位于句首时,句子要倒装.其结构为:Not until+从句/表时间的词+助动词+(主句)主语+谓语+.如:
①Not until the teacher came in did the students stop talking.直到老师进来学生们才停止讲话.
②Not until next week will the sports meet be held.直到下周才开运动会.
2.表强调:It is / was not until+从句/表时间的词+that+内容
③It was not until the teacher came in that the students stopped talking.
④It is not until next week that the sports meet will be held.
意思和上面的一样,我就打字了。

未倒装前的句子是:
The mother leave the room until the child fell asleep.
这是not until引导的倒装从句,主句用倒装语句,until引导的从句不倒装。
1.主句倒装时,如谓语是be动词,则把be动词提到主语前;
2.主句倒装时,如谓语是实意动词,则根据时态把do/have正确形式提到主语前;
3.主句倒装时如谓语动词是情态动词,则把情态动词提到主语前。追答
