有一读者问：我只知道 had better 的否定结构是 had better not,但不知它有没有疑问结构？
had better 用于疑问结构时，一般常用于一般否定疑问句，如：
(1)Hadn't we better go now?
肯定答语是：
(2)（Yes,）we'd better.
否定答语是：
(3)（No,）we'd better not.
had better 亦可用于反意疑问句，如：
(4)We'd better go, hadn't we?
用 had better 时，有以下几点值得注意：
1. had better 一般不用于一般肯定疑问句和特殊疑问句。
2. had better 往往并无比较之意，几乎等于汉语的“应该”。
3. You'd better...常有威逼的含义。
4. 对长辈不可用 You had better...结构。
