英语中not ...until的用法用什么?

三种
1普通
sb.+助动词/情态动词/be动词+not+.+until+.
We could not go out until our teacher came back.
2倒装（部分倒装）
Not+助动词/情态动词/be动词+.+until+.
Not could we go out until our teacher came back.
3强调
It be动词 not until +.+that+...
It was not until our teacher came back that we could go out.

not ... until，意思是直到...才....。比如we can't leave until 12:00 P.M.。我们直到半夜十二点才能离开。

not until:可放句首，但主句要用倒装．后面这个词组，我没看出与前面的有英语水平有限，自己判断为准。 1, 是dispute吧？争辩，争论的意思，
