词义辨析:should、ought、had better
1、should和ought to均用以表示应该做某事,不过should常用得多:

你应该把这婴儿带去看看医生。
2、在疑问句中,通常用should而不是ought to:
Should we call the doctor?
我们叫医生来好吗?
3、had better亦可用以表示在目前状况下最好做某事:
We’d better hurry or we’ll miss the train.
我们最好快点,否则就赶不上火车了。
4、过去时用should have或ought to have构成:

5、should not或shouldn't(以及在北美英语中很少见,在英国英语中为正式用法的ought not to或oughtn't to)表示不应该:
You shouldn’t drive so fast.
你不应该把车开得这么快。
6、should not have或shouldn't have以及很少用的ought not to have或oughtn't to have均用于指过去:

对不起,我不该发脾气。
had better do sth. 最好做某事
had better后面接不带to不定式,格式是:had better do sth,译为“最好做某事”,它所表达的语气很强。如果我们觉得有人不按要求或建议做会有负面结果,那么就用had better,例如:
It’s five o’clock. I’d better go now before the traffic gets too bad.
现在是五点钟。我最好在交通不太拥挤之前走。
You had better listen to what I'm saying before you get yourself into more trouble.
你最好先听听我说的话,免得惹麻烦。
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,作为一种劝告形式,比肯定形式的语气更委婉一点例如:
1、在一般疑问句,把had提到主语前,译为”…最好…?“,例如:
Had I better speak to Joan first before I send this form off? What do you think?
在我寄出这张表格之前,我最好先和琼谈谈吗?你觉得呢?
Had we better leave a note for the delivery guy to take the parcel next door?
我们最好留张纸条让送货员取隔壁的包裹?
2、在否定疑问句,把hadn't提到主语前面,译为”…是不是最好…?“,例如:
Hadn’t we better ring the school and tell them Liam is sick?
我们是不是最好给学校打个电话告诉他们利亚姆病了?
Hadn’t you better switch your computer off? It might overheat if you leave it on.
你是不是最好把电脑关掉?如果你开着它,它可能会过热。

例句

语法要点
1. had better 的基本用法特点
其意为“最好”、“应该”,后接动词原形,与情态动词should用法相似,其中的had通常缩略为 ‘d:
You’d better get some sleep.你最好去睡一会儿。
We had better go before it rains. 我们最好在下雨前就去。
2. had better 如何构成否定式和疑问式
构成否定式时,通常将not置于had better之后(而不是had之后);而构成疑问式时,则通常将had(而不是had better)置于主语之前:
I’d better not disturb him.我最好别去打扰他。
What had we better do? 我们最好怎么办?
【注】在否定疑问句或反意疑问句中可将not与had连用:
Hadn’t we better go now? 我们是不是现在就去呢?
3. had better 后接进行式和完成式动词
有时后接动词的进行式,表示最好马上做某事;也可接完成式动词,表示最好做完某事或本该做某事而未做某事:
I think I’d better be going.我想我最好还是马上走。
You’d better be getting your clothes ready. 你最好马上把衣服准备好。
You had better have done that. 你最好把那事做完。
You had better have stayed here. 你本来应该呆在这儿的。
4. had better的几点用法说明
(1) had better 用于提出建议或请求时,并不是一个很客气委婉的表达,它暗示对方有义务去做某事,因此通常用于长辈对晚辈或上级对下级等,而不宜反过来用。
(2) had best与had better用法和含义均差不多,但不如had better普通:
You had best get home before midnight.你最好在午夜之前回到家里。
We had best be going.我们最好现在就走。
(3) 有时可省略其中的had:
You better stop arguing.你们最好不要争论了。
Better not wait for him. 最好不要等他了。
Better say yes, if they ask you. 如果他们问你,你最好说“是”。
(4) 有时为了强调,可将better置于had之前:
"I promise I’ll pay you back." "You better had." “我保证还给你。”“你最好还给我。”
