not until 和until的区别

not until 和until的区别

UNTIL 一定要与延续性动词连用NOT UNTIL 可与短暂性动词连用I don\'t sleep until my mother came back.======以下答案可供参考======供参考答案1:not until意思是直到什么时候才会去做某事，否则不去做until一直到某个时候一直做某事供参考答案2: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 .供参考答案3:untilprep.(=to the time of)直到...时, 到...为止[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直到四点钟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这件事。两个不能说区别，因为not until本来就是until的否定，表示直到。。才供参考答案4:until一般不放在句首，后面跟时间词连用 如：He came back until midnight.not until:可放句首，但主句要用倒装． Not until midnight did he came back home. 还有一种用法与until相似． He did not come back home until midnight.供参考答案5:NOT UNTIL在强调句中要倒装

就是这个解释
