A It was,that B Not until,did
C It was,before D Until,did

答案是B 请问这种题目怎么看？
那用A 强调句为什么不可以呢？

若选A:整句应为过去时态,而谓语动词为原形,不对;
若选C:首先还是时态问题,若句中用"became",也不对,应去掉"after";
若选D:不是倒装,选B才是谓语动词倒装.

not until的倒装与强调结构

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. 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！
