•We use should when we talk about what we think is right,best or correct.

•We use have to to talk about what is necessary or compulsory.

•We also use must to talk about what is necessary or compulsory,especially when the subject of the verb is not a person or when the main verb is passive.

•We use must to talk about what we are sure is true.The opposite is can’t.
