should / ought / had better
Should and ought to are both used to say that something is the best thing or the right thing to do, but should is much more common: You should take the baby to the doctor's. + I ought to give up smoking. In questions, should is usually used instead of ought to:
Should we call the doctor?

Had better can also be used to say what is the best thing to do in a situation that is happening now: We'd better hurry or we'll miss the train.
You form the past by using should have or ought to have: She should have asked for some help. + You ought to have been more careful.
The forms should not or shouldn't (and ought not to or oughtn't to, which are rare in AmE and formal in BrE) are used to say that something is a bad idea or the wrong thing to do: You shouldn't drive so fast.
The forms should not have or shouldn't have and, much less frequently, ought not to have or oughtn't to have are used to talk about the past: I'm sorry, I shouldn't have lost my temper.
should / would
In modern English, the traditional difference between should and would in reported sentences, conditions, requests, etc. has disappeared and should is not used very much at all. In spoken English the short form 'd is usually used: I said I'd (I would) be late. + He'd (he would) have liked to have been an actor. + I'd (I would) really prefer tea.
The main use of should now is to tell somebody what they ought to do, to give advice, or to add emphasis: We should really go and visit them soon. + You should have seen it!
