Question

until和not until有什么区别

Answer 1

until 与not until的用法区别！

Answer 2

until 往往跟not连用。如：
He didn't get up until 9:00.他起到九点钟才起床。
She didn't finish her homework until the teacher came in.起到老师进来，她才做完家庭作业
如果要强调until引导的时间状语，则可以将 not 和until提前。这时句子要半倒装。如：
Not until 9:00 did he get up.
Not until the teacher came in did she finish her homework.

until的用法与汉语不同。如第一例，汉语是说九点以后的事，他九点钟以后才起床。而英语是说九点钟以前的事，他九点钟以前一直不起床，这种状态一直持续到九点钟才得以改变。

until有时也可以不跟not 连用。请看下例：
He lay in bed until 9:00.他在床上一直躺到九点钟。
