it was not until和 it was until的区别

题目

it was not until和 it was until的区别
it was not until 的意思是直到.才.可是后面的 it was until 是啥意思,按照意思来翻译难道不也是 --直到.才.
2者有区别吗?还是一个意思来着?

答案

it was not until ,it was until 都用于强调句结构,如
1 He didn't come until 8:00---------------It was not until 8:00 that he came(他直到八点才来)
2 He waited until / till 8:00 un the evening.----------It was till / until 8:00 that he waited（他一直等到八点）
