题目内容：

Was it not until you began to work -------how much time you had wasted?
A did you realize
B that you realized
C did you not realize
D that you didn't realize
我选了A错了,not until的句子不倒装吗?

优质解答

这个句子改成肯定就是：
It was not until...that...
是一个强调句.
而如果Not until放在句首,那么就要倒装.
即Not until you began to work did you realize ...
