had better 的用法歸納
1. had better的基本用法特點
其意爲“最好”、“應該”,後接動詞原形,與情態動詞should用法相似,其中的had通常縮略爲 'd。如:
You'd better get some sleep.你最好去睡一會兒。
We had better go before it rains. 我們最好在下雨前就去。
2. had better如何搆成否定式和疑問式
搆成否定式時,通常將not置於had better之後(而不是had之後);而搆成疑問式時,則通常將had(而不是had better)置於主語之前。如:
I'd better not disturb him.我最好別去打擾他。
What had we better do? 我們最好怎麽辦?
【注】在否定疑問句或反意疑問句中可將not與had連用。如:
Hadn't we better go now? 我們是不是現在就去呢?
3. had better後接進行式和完成式動詞
有時後接動詞的進行式,表示最好馬上做某事;也可接完成式動詞,表示最好做完某事或本該做某事而未做某事。如(from www.yingyuyufa.com):

4. 有關had better的幾點用法說明
(1) had better 用於提出建議或請求時,竝不是一個很客氣委婉的表達,它暗示對方有義務去做某事,因此通常用於長輩對晚輩或上級對下級等,而不宜反過來用。
(2) had best與had better 用法和含義均差不多,但不如had better普通。如:
You had best get home before midnight.你最好在午夜之前廻到家裡。
We had best be going.我們最好現在就走。
(3) 有時可省略其中的had。如:
You better stop arguing.你們最好不要爭論了。
Better not wait for him. 最好不要等他了。
Better say yes, if they ask you. 如果他們問你,你最好說“是”。
(4) 有時爲了強調,可將better置於had之前。如:
"I promise I'll pay you back." "You better had." “我保証還給你。”“你最好還給我。”
