GRAMMAR SECTION: MODALS 2

(OBLIGATION, PROBABILITY, POSSIBILITY)

 

Review the modal verbs

 

We use modal verbs when we want to express obligation, probability and possibility.

 

1.- Obligation

 

We use must/mustn’t, have to and need to to express present or future obligation.

-Everyone must turn their mobile phones to silent when they are in the library.

 

We use don’t have to, don’t need to and needn’t when we talk about something we weren’t obliged to do in the present or future.

-You don’t have to/don’t need to/needn’t eat something you don’t like.

 

We use had to when we talk about obligations in the past.

-Last year, I had to take the metro to work every day.

 

We use didn’t have to and didn’t need to when we talk about something that we weren’t obliged to do in the past.

-I learnt a little Spanish before travelling to Spain, but I didn’t have to/didn’t need to use it because everyone spoke some English.

 

It’s important to know that in spoken English we use have to more often than must. It’s more common to see must in formal written notices.

 

It’s also important to note the difference between mustn’t and don’t have to.

-You mustn’t go there! (You can’t go there.)

-You don’t have to go there. (You can go there if you want to, but it’s not necessary.)

 

 

2.- Probability

 

We use must/ can’t/couldn’t to express a strong probability that something will or won’t happen in the present.

-Someone is knocking on the door – it must be Andrew.

-This present can’t/couldn’t be from Christy because she’s out of town.

 

We use should/ought to when talking about probability that something will or won’t happen in the present or the future.

-They should/ought to take a holiday soon.

 

 

3.- Possibility

 

We use could/may/might when we talk about possibility in the present and future.

 

I’m not sure who is calling – it could/may/might be Mike.

I’m not sure what language that is written in – it could/may/might be Cambodian.
