not…until三种句型
not…until有三种句型,即:正常语序、倒装语序和强调句型。
(1)正常语序

I didn’t know the truth of it until the next day.
(2)倒装语序
Not until the child fell asleep did the mother leave the room.
Not until the next day did I know the truth of it.
(3)强调句型

It was not until the next day that I knew the truth of it.
(4)注意事项
①在not…until句型中,主句中的动词均为短暂性动词,如leave,start等。而在until的肯定句型中,主句的谓语动词一定要用延续性动词,因为until作为连词和介词意为up to the time when; up to“直到……时”。如:
②until只连接表示时间的短语和从句,不能用于地点和数量。如:
We walked until the edge of the forest.(误)
Our classroom can hold until fifty students.(误)
