until (直到··开始·做·)
not until(不做··直到··时候)
He came back until midnight.
他直到夜里才回来。
He did not go until night.

He came back until midnight.
他直到夜里才回来。
He did not go until night.
他直到夜里才走。 (到夜里之前没有走)
用法上:
until表示的意思是"做某事直至某时",动词必须是延续性的。
not until表达的意思是"直至某时才做某事"。动词为延续性或非延续性都可以。
另外:
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.
until
prep.
(=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
It was not until yesterday that I noticed it.
直到昨天我才注意到这件事。

楼上说的很详细 我来加点
not until的倒装与强调结构
1.当Not until位于句首时,句子要倒装。其结构为:Not until+从句/表时间的词+助动词+(主句)主语+谓语+...。如:
①Not until the teacher came in did the students stop talking.直到老师进来学生们才停止讲话。

②Not until next week will the sports meet be held.直到下周才开运动会。
2. not until的强调结构为:It is / was not until+从句/表时间的词+that+...。上面两句改为强调句为:
③It was not until the teacher came in that the students stopped talking.
④It is not until next week that the sports meet will be held.
因此呢,现在的用法属于not until 的强调结构。这种用法很常见哦!

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,No until放在句首的时候要倒装,并且,是『前不倒后倒』。前不倒后倒啥意思??...

这个意思:Not until I got home, did I found......
这个要区别于:『前倒后不倒』的几个特殊例子:
not only but also
no sooner than,hardly when.....就这三个特殊
1. I studied 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
