MODAL VERBS

Modal verbs do not use the s in the 3rdperson singular and are followed by a verb without to, with the

exception of have to.

CAN CANT:We use can + verb to express ability, possibility and permission. We also use cant when we

believe that something is not possible.

I can swim fast

You can use my umbrella

Can I go out?

It cant be possible are you joking?

COULD COULDNT:We use could + verb to express ability and possibility in the past.

I could swim fast when I was three years old

She could pass her exams

BE ABLE TO: We use be able to with the same meaning as CAN. The difference is that BE ABLE TO can be

used in more verb forms than CAN & COULD (present/past).

I havent been able to sleep recently.

WOULD WOULDNT:We use this modal when we think of something that is not real, we just imagine

that.It would be nice to buy a new car but I cant afford it.

HAVE TO:We use have to + verb to talk about obligation.

You have to be here at one oclock

DONT HAVE TO:We use dont have to + verb to express lack of obligation.

You dont have to get up early.

SHOULDSHOULDNT:We use should + verb to give suggestions and advice.

We should make the party here

You should go by taxi

We shouldnt go to the party tonight because tomorrow we have an exam.

MUST:We use must + verb to express obligation.

You must have a license to drive

MUSTNT:We use mustnt + verb to express prohibition.

MAY:We use may to express possibility and permission.

You may pass your exam if you study harder.

You may go to the trip with your classmates.

MIGHT:

We use might to talk about probability, which is less possible than may.

It might rain tomorrow.

NEEDNT:We use neednt when wetalk about something which is not necessary to be done.

You can come with me if you like but you neednt come if you dont want to.

MODAL PERFECTS

The modal perfects work in a different way than the usual modal verbs. The difference is in the verb that

follows them. That is to say that the verb we use after the modal perfects has to be in the past participle

form.

COULD HAVE:We use could have when we talk about a possibility in the past which didnt happen. In

other word something that could happen but didnt happen.

I could have wait for you if I had known that you were coming.

WOULD HAVE: We use would have when we imagine situation or actions in the past, but things thatdidnt happen.

They helped us a lot. I dont know what we would have done without their help.

SHOULD HAVE:We use this modal when we express something we expect to happen in the past. In other

words, something that it wasnt made but it would have been the right thing to do. If we use SHOULDNT

HAVE we want to express just the opposite idea.

You missed a great party last night. You should have come why didnt you?

MUST HAVE:We use must have to express a supposition or certainty that something is true.

Theres nobody at home. They must have gone out.

MAY HAVE MIGHT HAVE:We use these two modal perfects to talk about a possibility of something in

the past.

They may have been asleep.

She might not have known about the accident.
