问题：until与not...until用法上有什么不同？补充：是不是 
补充：是不是有哪个分用瞬间动词与连续性动词？
回答：until / not...until之间的区别：until“直到”,表示某一种行为一直持续到某一时间。用在肯定句中，句子的谓语动词必须是可延续性的。 not...until“直到...才”表示直到某一时间,某一行为才发生,之前该行为并没有发生. 用在否定句中，主句中的谓语可以是延续性的也可以是短暂性动词。1. I studi Englis until 9 o'clock last night.我咋晚学英语一直学到9点钟.(表示9点前一直在学)2. I did not study Englis until 9 o'clock last night.我咋晚直到9点钟才学英语.(表示9点才开始学)3. I waited for five hours until it was dark. I had to give it up.4. I didn't go to sleep until 11 o'clocknot until 还可以用于强调句中，也可以放在句首，句子要采用部分倒装5. It was not until he came back that I went to sleep6. Not until he came back did I go to sleep.
