| 标题 | 2013高考英语备考：not…until 用法说明 | |||||||||||||||
| 内容 |
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 The mother didn’t leave the room until the child fell asleep. 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 child fell asleep the mother left the room. 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)
