You had better....

昨天有學生問，如果要對人說「你最好聽我講」，英文是不是 "you better listen to me"？

正確的講法應該是： 

You had better listen to me.
You'd better listen to me.

日常對話中，我們通常會把 "you had better" 簡化為 "you'd better"。（注意：不是 "you better")

留意 "had better" 之後的動詞是原形動詞 (bare infinitive)。

It's very late now; we'd better go home.
(= 現在很晚了，我們是時候回家。） 

You had better start preparing for the HKDSE English exam!
(= 你最好現在就為香港中學文憑英文試作準備！）
