当He had better do it now.变否定句时加not，not应加在better前还是better后，为什么？请说的详细一些。
谢谢！！！谢谢！！！谢谢！！！谢谢！！！谢谢！！！谢谢！！！谢谢！！！
少说废话，谢谢！

加在better后面。。。

具体为什么。我也不知道。。我是这样理解的：这是个固定的语法搭配，had better必定是在一起的，相当于一个情态动词，所以not 应该该加在better后面。

我不一定是对的。。但是希望对你有启发！

I don't known

had better do sth是什么意思 had better do （do是否受人称变化） Ithink he could have played better than he (do). YOU’D BETTER DO IT NOW better had had better do sth可以默认为一般过去式吗 The moment he had said this,he regretted it. It's better to do A than do B He will do better in Enghish. 中文什么意思 I drove quickly just now. He tell to me"You'd better not do it."中的not可以用don't替换吗？
