not 和until 所修饰的时态的关系,麻烦写下几个例句给讲解一下.
那My dad had not come until I went to bed.和We will not leave until he comes .这两句对不对?
不太明白...

not后面一般现在时 until后任何时态都可以
其它情况保持一致

这个得靠理解来记忆~

not...until... 句式与高考   not...until...是英语中的常见句式,该句式具有灵活多变的特点,常以不同形式的句式出现,是英语学习中的重点和难点。

not放在be动词 助动词 情态动词后面 行为动词前面until一般放在时间状语从句前,意思直到 才
例如He did not tell me anything before he left here因为已经发生 所以用一般过去时
补充 not until等于not before等于after
not before的用法一样

1.I didn't go to bed until the TV play was over.
2.We waited at this bus stop until the NO.5 bus came.
3.The boys and girls didn't stop making noise until the teacher entered the classroom.
4.I kept silent until the teacher asked me.
5.I didn't know anything about it until he told me
