倒装句式

部分倒装句式，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。 not until we finished our work did he come not until midnight did he return 2. not until的强调结构为:It is / was not until+从句/表时间的词+that+...。上面两句改为强调句为: 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.
