not_until用法总结PPT课件
not-until的倒装结构讲解学习
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 comenot 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！我在看关于部分倒装的教程时看到：“当not until引出主从复合句，主句倒装，从句不倒装。
”不太理解，可以造个句子给我讲解下吗。
Not until I saw the score did I realize I hadn't work hard.直到我看到分数,我才意识到自己没有努力学习I realized I hadn't work hard是主句,倒装就成了did I realize ...Not until I saw the score 是状语从句,不用倒装典型例题1) Why can't I smoke here?At no time___ in the meeting-roomA. is smoking permittedB. smoking is permittedC. smoking is it permittedD. does smoking permit答案A. 这是一个倒装问题。

not until 句型用法
not ... until 意为“直到……才”，表示主句谓语的动作直到until状语的时间才发生，主句的谓语动词表示的是动作的开始。
until引导从句时，如果主句中的谓语动词是延续性动作，则主句用肯定式；如果主句中的谓语动词是短暂性动词，则用否定形式。
until可用作介词或连词，意为“到……时候为止”、“到……时候才”或“在……时候以前不”。
什么情况下表达什么意思，关键要看（主）句中的谓语动词是终止性动词还是延续性动词。
1. 如果（主）句中的谓语动词是终止性动词，应采用“... not ... until ...”结构，意为“……到……时候才……”。
例如：You mustn’t eat anything until you see the doctor.看过医生之后，你才能吃东西。
Don’t get off the bus until it has stopped.车停稳了以后再下车。
2. 如果（主）句中的谓语动词是延续性动词，那么谓语动词用肯定式或否定式，它们所表达的意思有所不同。
1）如果谓语动词为肯定式，则until译为“到……时候为止”。
例如：I watched TV until she came back.我看电视一直看到她回来。
2）如果谓语动词为否定式，则until应译为“到……时候才”，即“在……以前不”。
例如：I did not watch TV until she came back. （= I began to watch TV when/after she came back.）直到她回来我才开始看电视。
3. 用终止性动词作谓语时，until既可以和not连用，又可以和never，nobody，nothing，few，little，seldom，hardly等含否定意义的词连用。
例如：I had not seen him until 1990. （= I had never seen him until 1990.）1990年以前我从未见过他。
