4TH ESO MODAL VERBS REVISION.
Modals of Ability: Can, Could, Be able to, May, Might
Introduction
These five verbs are examples of modal verbs.





can
could
be able to
may
might
Modal verbs are helping/auxiliary verbs that express ideas like ability, permission, possibility, and
necessity. Many modal verbs have more than one meaning. They are always followed by the simple form
of a verb. For example,
Alan can swim well.
This shows that Alan has the ability to swim.
1. Modals for Ability
Let’s start with expressing ability! We use can, be able to and could to show that someone has (or
doesn’t have) an ability to do something.
Look at these examples:
Present/Future
Ability
Negative
Past Ability
Negative
Alan can swim well.
Jackie cannot play
piano.
Paul could speak Chinese
when he was a child.
Mary couldn’t finish
her homework last
night.
I can meet you after
school.
We can’t visit
Vancouver this
weekend.
Last night, there were no
clouds in the sky and they
could see all the stars.
You couldn’t find
the website this
morning, could you?
I am able to speak
two languages.
I am not able to
speak Arabic.
When I was a young
child, I wasn’t able to tie
my shoes.
I wasn’t able to
finish my test
yesterday.
Brenda is able to run
quickly.
Stacey isn’t able to
finish a marathon.
Shaun was able to
complete the assignment.
Paula wasn’t able to
pass the class.
You are able to
program a computer.
We aren’t able to
make a reservation
They were able to catch
six fish on their trip.
You weren’t able to
understand the
tonight.
answer, were you?
Did you notice that the verbs after “can/could/be able to” are always in the simple form? For example:
Alan can swim well.
(subject + auxiliary verb + simple verb + ...)
Do NOT change the modal auxiliary OR the main verb for he/she/it subjects. In addition, do not add
“ing” or “ed”.
Alan can swims well.
Wrong!
Alan can to swim well.
Alan can swimming well.
Alan could swam well.
Wrong!
Wrong!
Wrong!
How can we make questions about ability? It’s easy!
Modal auxiliary + subject + main verb + ... ?
Can she play guitar?
Could you speak English when you were a child?
BE + subject + able to + main verb + ... ?
Are you able to understand the homework?
Were you able to finish the test?
Was he able to pass the exam?
Notice that we do not need the verbs “do/does/did” when we make questions!
The modal verb “be able to” includes the word “to”; the “to” is not an infinitive.
2. Modals for Possibility
Let’s learn about expressing possibility now.
The verbs may, might and could show possibility now and in the future. In this case, they have the same
meaning.
Look at this conversation:
A: My mother said that it may snow tomorrow.
B: Really? It might snow?! That’s great! I could make a snowman or go for a “snow” walk.
A: Don’t get too excited. If the temperature is high, it may not snow. It may rain.
B: Well, I guess I could still go for a walk in the rain.
Be careful with may + “be” and “maybe”. Compare these sentences. Both are correct.
Ann is not here today. She may be sick.
Ann is not here today. Maybe she is sick.
3. Modals for Permission
“may be” is a modal.
“Maybe” is an adverb.
Finally, let’s look at ways to ask for and give permission. We use may, could and can to do this.
Formality
Example
most formal/polite
May I go to the washroom?
*only used with “I” and “we”
medium formal
Could I borrow your dictionary?
Could he pay you tomorrow?
casual
Can I call you back later?
Can she have a cookie?
Now, look at the (main) verbs that come after the subject. They are always in the simple form, just as
with other modal verbs.
Again, the most polite/formal way to answer these questions is with “may.”
Examples:
May I go to the washroom?
Yes, you may (go to the washroom).
Yes, you can.
No, you may not.
No, you cannot.
Can she have a cookie?
Yes, she can.
No, she can’t.
Notice that we do not “contract” may + not = mayn’t.
Wrong!
Can’t and couldn’t are common contractions, however.
When you are sure that you understand the lesson, you can continue with the exercises.

Modals of Advice: Should, Ought to, Had better
Introduction
These three verbs are modal verbs.



should
ought to
had better
Modal verbs are helping/auxiliary verbs that express ideas like ability, advice, and obligation. Many
modal verbs have more than one meaning. They are always followed by the simple form of a verb. For
example:
Amanda should go to the doctor.
This shows that we think it is a good idea for Amanda to visit the doctor.
Modals for Advice
Let's learn how to give advice!
English speakers use the modal verbs “should,” “ought to” and “had better” to express that they think
something is a good (or a bad) idea. “Should” is the most common way to give advice.
Look at these examples:
Affirmative
Negative
Question
A: I failed my test.
B: Really? You should
study harder.
Young children shouldn't watch
violent TV shows.
I have a problem. Should
I call my parents or my
friend?
A: It's really cold outside.
B: You ought to wear a
warm jacket.
(“ought to” is not usually used in the
negative form)
(“ought to” is not common
in question form)
A: You had better slow
down. You are driving too
fast!
You had better not forget to pay
your tuition. If you do, the university
will kick you out!
(“had better” is not
usually used in question
form)
These examples have the same basic advice message, but “had better” is a bit stronger. It includes the
idea of a warning: something bad will happen if you do not follow my advice. For example:
You had better not forget to pay your tuition. If you forget, the university will kick you out
You had better do your homework. If you do not do your homework, the teacher will give you a low
mark.
Note: “You had better...” can be contracted to become “You'd better....” This is correct grammar, and
very common in speaking. Some native speakers say, “You better ...,” but this is incorrect. The “had” is
necessary in good grammar.
In the above examples, you can see that the modals are followed by the simple form of a verb in these
patterns.
Subject + modal + basic verb + ...
You should to study harder.
You had better slowing down.
She ought to to drink more water.
You should study harder.
Wrong!
Wrong!
Wrong!
Remember that “ought to” is a modal verb and is followed by a simple verb. The “to” is not an infinitive
“to.”
Modal + subject + basic verb + ...??
Should I call my parents or my friend?
WH- (information) questions can also be formed by putting the WH- question word immediately before
the modal.
For example:
What should I do about my problem?
Where should we have dinner tonight?
Why should you believe them?
When should they call their boss?
When you are sure that you understand the lesson, you can continue with the exercises.

Modals of Polite Request: Would you, Could you, Will you, Can you
Introduction
These four questions are made with modal verbs:




Would you... ?
Could you... ?
Will you... ?
Can you... ?
Modal verbs are helping/auxiliary verbs that express ideas like ability, permission, and asking for
assistance. Many modal verbs have more than one meaning. They are always followed by the simple
form of a verb.
For example:
Could you help me for a minute, please?
This shows that the speaker is asking for help politely.
To ask questions in a very polite way, use: Would you/ Could you (please) + simple verb + ...?
For example:
Would you please email that document to me? I need it ASAP*.
Could you explain that again, please? I didn’t understand.
*ASAP = as soon as possible
To ask questions in a polite but more casual way, say: Will you/ Can you (please) + simple verb + ...?
For example:
Will you please answer the phone? I’m working.
Can you hold my books for me? My hands are full.
We do not use the word “may” in a polite question when “you” is the subject.
For example:
May you please close the door?
Could you please close the door?
Wrong!
Right!
The word “please” makes the request more polite and less direct. Canadians use “please” often and
visitors are expected to ask for help politely, using “please.”
Possible positive answers to the questions above:
Yes.
Yes certainly.
Certainly.
Informally, we can say:
Yes, of course.
Of course.
I’d be happy to.
I’d be glad to.
My pleasure.
Sure.
Okay.
Uh-huh. (means yes)
To answer negatively, we say:
No.
Sorry.
No, I’m sorry. I can’t.
Sorry, I can’t. I’m busy right now.
I’d like to, but I can’t.
I’d love to, but I’m busy right now.
When you are sure that you understand the lesson, you can continue with the exercise.
