为什么是that 而不是when 或/
是强调句,意思是直到12点我才完成了我的作业.
而把until去掉,再把that换成when的话意思是当我做完作业时是12点,而这个句子不是定语从句,不能用/
因为it is....that是一个强调句的句型
如果没有until的话
用when也可以
因为when指的是一个瞬间的状态
强调句固定形式it is ...that
It is ...that ...是固定用法，表强调.
其次when 是引导时间状语，按照句子的翻译，是说直到十二点我才做完作业，不十要强调我完成作业了在十二点。那样的话就用when .定语从句了。
It isn't until 12o'clock that he do sth ,为什么不用it is until?
it is not until的用法

带it is that强调格式的not until用法
It is not until that.....(强调句)中not until算在句首吗,主句倒装吗?
