not until的用法？

Question

如题所述

Answer 1

回答如下：
英语句型 "...not ...until / till..." 的意思是“直到……才……”。该句型表达此意时，主句动词通常是非延续性动词。例如：
1. He didn't leave until I came. 直到我来了他才离开。
2. They went upstairs and didn't reappear until morning. 他们上楼了，直到早上才再次出现。
本句型还可以转换成倒装句型：Not until ... + 倒装句。例如：
3. Not until I came did he go to bed. 直到我来了他才去睡觉。
4. Not until six o'clock did I saw her. 直到六点钟我才见到她。
本句型还可以转换成强调句型：It is not until ... that ...。例如：
5. It was not until yesterday that he came. 直到昨天他才来。
6. It was not until the sun went down that they went home. 直到太阳落山了他们才回家。
如果句型" ... not until ..."中的主句谓语动词是延续性动词，其意思是“没有一直到……”。例如：
7. He didn't work until eight o'clock. 他没有工作到八点钟。
8. We didn't wait until he came home. 我们没有等到他回家。
