1）had better表示“最好做某事”，had雖然是過去式，但不表征過去，better后面接動詞原形。

He had better eat more.

他最好多吃點

You'd better finish it right now.

你最好馬上把它做完

2）would rather表示“寧愿、寧可、最好、還是……為好”，語感上比“had better”要輕更委婉，后面接動詞原形。

You would rather deal with it now.

你還是現(xiàn)在把它處理掉為好

3）否定形式分別為：

had better not+動詞原形

would rather not+動詞原形

He had better not eat more.

他最好別再吃了

You would rather not deal with it now.

你最好現(xiàn)在別處理那件事
