you'd better反意疑问句到底用wouldyou 还是had you?

Answer 1

had better通常不以普通疑问句的形式出现.但有时用于否定疑问句,常用Hadn't+主语+better...结构,作为一种劝告形式,比肯定形式的语气更婉转一些.如：
Hadn't you better take an umbrella?你不认为该带一把伞吗?
Hadn't you better ask him first?你不认为该先问问他吗?
.had better在反意疑问句中：
在反意疑问句中,疑问部分一般用"had+主语?",但有时可用"will you?"表示一种请求或建议.如：
You'd better not go out today,had you?今天你最好不要外出,好吗?
I must stay at home this afternoon.You had better come to my house,will you?今天下午我必须留在家里,你最好来我家,好吗?
