404　had better, would like和should like

1　had better 可缩写成'd better ，意为“最好”，应看作情态动词，通用于所有人称，had不可改为have或has。had better 后跟动词原形，不可跟不定式。had better 的否定式为had better not ，不是had not better。

You have better start right now. （误）

You had better start right now. （正）你最好马上动身 。

You had better don't go there. （误）

You hadn't better go there. （误）

You had better not go there. （正）你最好不要去那里 。

2　would like 可缩写成'd like。would like 用于礼貌地向对方提出请求或邀请，也表示说话者本人喜不喜欢做某事，后跟名词或不定式。

Would you like some coffee? 喝点咖啡好吗？

I'd like some tea. 我想要茶。

Would you like to have another try? 你想再试一下吗？

提示

would like用于疑问句表示请求或邀请时，肯定回答通常用“Yes， I'd love to.”，否定回答用“I'd love to， but...”。

3　should like 通常只用于陈述句，不用于疑问句，表示说话者本人愿意做什么或想做什么，后跟不定式，也可表示想要什么，后跟名词。
