must, ought to and should do not have Past Simple forms
Modal verbs can, must and should are also called modal auxiliaries. Like the related verbs have to, ought to and be able to they are used for rules, responsibilities and ability.
To form sentences with these verbs:
don’t add third person s except with have/has to and am/are/is able to.
use have to instead of must and should instead of ought to for questions.
don’t use the auxiliary do -in questions, negatives or short answers, except with have to.
We use must for
written rules: All students must show their ID cards.
things which we think are important to do: I must do some revision this weekend.
strong advice: You must stop drinking cola.
We use mustn’t when something is
forbidden by law/rule: You mustn’t use a mobile phone in the hospital.
an obligation: We mustn’t forget to buy Jim a birthday card.
We use have to for
rules: If you lose a library book, you have to buy a new one.
laws: You have to get a visa to travel to the USA.
external obligation: He has to do his homework first.
We use dontaskt have to
when something isn’t necessary: You don’t have to buy me a birthday present — a card is enough.
We use should/shouldntaskt and ought/ought not to to
give advice: You shouldn’t get married after only two weeks together! You ought to wait at least a year.
explain a duty or responsibility: If you saw the accident, you ought to phone the police.
make suggestions: You shouldn’t spend so much money./You ought to see a doctor.
We use can/can’t (present) and could/couldn’t (past) for
ability: I could understand the joke, but I didntaskt think it was funny.
possibility: You can go there by train, coach or plane.
permission: You can go when the light is green.
laws: People couldn’t vote at eighteen when I was young.
rules: You can’t make noise in my house.
We use the correct form of be able to for ability, in tenses where there is no appropriate form of can:
Itaskll be able to paint your kitchen next weekend./They won’t be able to come to your party.
