Unit 8. Modals: can, could and (be) able to, may, might
MODAL VERBS are a small group of verbs that are used with other verbs to change their meaning in the sentence in various ways.
MODAL VERBS are used with other verbs (in front of a verb) to express the speaker’s opinion at the time of speaking. They express the speaker’s attitude towards an event, a situation or the person they are speaking to.
We use MODAL VERBS, not for situations / things that have definitely happened, BUT to talk about things we expect, which are possible, which we think are necessary, which we are not sure about, etc…
Differences from other English verbs:
They have no infinitive form or participles.
They do not need auxiliary DO = questions and negatives are made without do, does, did:
Question - Can we go now?
Negative - I can’t ride a bike.
They have no - s in the 3rd person singular:
Mary can swim very well and Mary should learn it before her trip to Brazil.
They do not normally stand alone. They are nearly always used in front of a verb. The main verb is always an Infinitive without to:
Jane might arrive before dinner, but I doubt it.
A few modals are followed by to:
Perhaps you ought to see a doctor.
Can
He can swim. He can’t swim.
1. Can is used to express the ability to do something.
I can swim very well.
Can he speak English fluently? - No, he can't.
We cannot sing at all!
2. It expresses the possibility to do something.
We can go to the seaside at last. Our holidays start next week.
3. We use it to say that something is probable.
It can be John. He has blond hair and he is wearing glasses.
4. It expresses the permission to do something.
Why not? You can marry her. She is a nice girl.
We use can + infinitive (can do/can see etc.):
We can see the lake from our bedroom window.
Can you speak any foreign languages?
I can come and see you tomorrow if you like.
The negative is can't (= cannot):
I'm afraid I can't come to the party on Friday.
(Be) able to ... is possible instead of can, but can is more usual:
Are you able to speak any foreign languages?
But can has only two forms, can (present) and could (past). So sometimes it is necessary to use (be) able to...
Compare:
I can't sleep.
BUT: I haven't been able to sleep recently. (can has no present perfect)
Tom can come tomorrow.
BUT: Tom might be able to come tomorrow. (can has no infinitive)
Could and was able to...
Sometimes could is the past of can. We use could especially with:
see hear smell taste feel remember understand
When we went into the house, we could smell burning.
She spoke in a very low voice, but I could understand what she said.
We also use could to say that somebody had the general ability or permission to do something:
My grandfather could speak five languages.
We were completely free. We could do what we wanted. (= we were allowed to do ...)
We use could for general ability. But if we are talking about what happened in a particular situation, we use was/were able to... or managed to... (not could):
The fire spread through the building quickly but everybody was able to escape.
or ... everybody managed to escape. (but not 'could escape').
Compare:
Jack was an excellent tennis player. He could beat anybody. (he had the general ability to beat anybody)
BUT:
Jack and Alf had a game of tennis yesterday. Alf played very well but in the end Jack managed to beat him. or ... was able to beat him. (= he managed to beat him in this particular game)
The negative couldn't (could not) is possible in all situations:
My grandfather couldn't (could not) is possible in all situations
We tried hard but we couldn't persuade them to come with us.
Alf played well but he couldn't beat Jack.
Could is also used in the future (especially to make a suggestion):
Can is also possible in these sentences ('We can go for a walk,' etc.). Could is less sure than can. You must use could (not 'can') when you don't really mean what you say:
I'm so angry with him. I could kill him! (not 'I can kill him').
We also use could to say that something is possible now or in the future:
The phone is ringing. It could be Tim.
I don't know when they'll be here. They could arrive at any time.
Can is not possible in these examples (not 'It can be Tim').
Sometimes could means 'would be able to...':
We could go away if we had enough money. (= we would be able to go away)
I don't know how you work so hard. I couldn't do it.
May and might
1. May is used for permissions.
You may borrow my car. I won't need it.
May I smoke here? – No, you can't, I'm sorry.
2. May is used to express probability or prediction.
They may call tomorrow. I hope so.
The main difference between may and can is in style. May is more formal than can. Can is typical of spoken English.
3. The opposite of may is must not or may not.
May I smoke here?
- You mustn't smoke here. (strong prohibition)
- You may not smoke here. (more polite, very formal)
- You can't smoke here. (informal spoken English)
Study this example situation:
You are looking for Bob. Nobody is sure where he is but you get some suggestions.
You: Where's Bob?
He may be in his office. (= perhaps he is in the house)
He might be playing in the yard. (= perhaps he is playing in the yard)
Ask Ann. She might know. (= perhaps she knows)
We use may or might to say that something is a possibility. Usually you can use may or might you can say:
It may be true. or It might be true. (= perhaps it is true)
She mightn’t know. or She may not know.
Sometimes could has a similar meaning to may and might:
The phone's ringing. It could be Tim. (= it may/might be Tim).
You could have left your bag in the shop. (= you may/might have left it...).
But couldn't (negative) is different from may not and might not.
Compare:
She was too far away, so she couldn't have seen you. (= it is not possible that she saw you).
A: I wonder why she didn't say hello.
B: She might not have seen you. (= perhaps she didn't see you; perhaps she did).
We use may and might to talk about possible actions or happenings in the future:
I haven't decided yet where to spend my holidays. I may go to Ireland. (= perhaps I will go to Ireland)
Take an umbrella with you when you go out. It might rain later. (= perhaps it will rain)
Usually it doesn't matter whether you use may or might. So you can say:
I may go to Ireland. or I might go to Ireland.
But we use only might (not may) when the situation is not real:
If I knew them better, I might invite them to dinner. (The situation here is not real because I don't know them very well, so I'm not going to invite them. 'May' is not possible in this example.)
