为什么did better后面加not而不加的do not

你可能是写错了吧，是不是想问had better 后面加not的原因啊因为had better 是动词词组表达否定式时，就直接加not，而加入do not，就会出现两个动词（动词词组在句中就是动词的作用和性质，只是以词组的形式出现而已和动词do连用）连用的不合理现象。其实有时动词也可以来能用那都是一些特例，比如表示强调时do可以用在动词前面。

did better 过去时态，做得好 i did better last year
had better （not)do sth 最好（不）做某事
you had better work hard. 你最好努力学习
