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！！！

had better其实就是'd better
You'd better go home ealy.=You had better go home ealy.
同理
You'd better not go there yourself.=You had better not go there yourself.

better 后

固定用法sb had better do sth简写为sb'd better(not) do sth

had better 合起来相当于一个情态动词，所以否定式为 had better not

had better 否定是直接在后面加not

放在better后面，是固定用法

had better 否定是直接在后面加not

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？
