Notuntil开头,倒装句的用法

Question

Not until 开头,倒装句的用法

Answer 1

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.
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.
因此呢,现在的用法属于not until 的强调结构.这种用法很常见哦!
