大家好，小好來為大家解答以上問題。notuntil的用法口訣，notuntil的用法很多人還不知道，現(xiàn)在讓我們一起來看看吧！

1、until 是直到.如:You have to stand on it until you can go against it .not until 是在...之前 如:You can not go against it until you can earn your life .until一般不放在句首,后面跟時(shí)間詞連用 如：He came back until midnight.not until:可放句首,但主句要用倒裝． Not until midnight did he came back home.還有一種用法與until相似． He did not come back home until midnight.until prep.(=to the time of)直到...時(shí),到...為止 [常用在否定句中](=before)在...以前; 直到...才; 不到...(不) until his death 直到他死 until four o'clock 直到四點(diǎn)鐘 He did not go until night.他直到夜里才走.It was not until yesterday that I noticed it.直到昨天我才注意到這件事.兩個(gè)不能說區(qū)別,因?yàn)閚ot until本來就是until的否定,表示直到.才。

本文到此結(jié)束，希望對大家有所幫助。
