Modals (sometimes called modal auxiliaries) can be used in several
different ways, but they are always followed by the bare infinitive.
For instance, I just mentioned can be; not *can am, *can is, or *can are.
The box that follows contains a list of modal auxiliaries.
can, could, may, might, should, shall, will, would, must, ought to, have to
As I mentioned, there are many faces (that is, uses) of modals.
Let’s look at the following examples to figure out just how to use them.
Can and could are used to indicate…
1. Kyosuke
can throw a football almost perfectly.
2. Len
can play American football, but he
cannot play soccer.
3. Paolo
could never dunk a basketball.
Can and may are used to indicate…
1.
Can/May I smoke near the building?
2.
Can/May I go to the restroom?
Can and may are used to indicate…
1. Anybody
can make a mistake.
2. The road
can be blocked.
3. It
may rain.
4. The road
may be blocked.
In the cases directly above, the modals can and may are used differently.
Can you figure out the difference between sentence number 2 and sentence number 4?
In sentence number 2, The road can be blocked, we mean “It is possible
to block the road (that is, it is theoretically possible). However, in sentence
number 4, there is factual possibility, not just theoretical possibility.
In other words, in the latter sentence, there is the possibility that the road
is actually blocked.
The modal could is used to indicate present or future permission,
present possibility, and contingent possibility or ability in unreal
conditions. Note the examples below:
1. Yukie,
could I have another donut? They’re delicious.
2. The road
could be blocked.
3. If Marco had more money, he
could buy his girlfriend a Ferrari.
May is used to indicate…
1. Florencia, you
may borrow Marco’s car if you like.
2. You
may not eat in the computer classroom.
Might is used to indicate…
1. What Lea is saying
might be true.
2. Saray
might have a glass of beer tonight.
Note: Might is also used to make suggestions.
Shall is used to indicate…
1. You
shall do as I say, and nothing else.
Should has a number of different uses. Refer to the table below.
Obligation, necessity | You should do as he says. |
Contingent use (1st person only) | We should/would love
to extend at our school (if we had the money). |
Formal real conditions | If you should change your mind,
please let us know. |
Will and would also have several different uses. Refer to the table below.
Willingness. Polite requests. | He’ll help you if you ask him.
Will you have another cup of coffee? |
Intention | I’ll write as soon as I can. |
Insistence | He will do it. |
Prediction | The game will be finished by now. |
Note how would is used. Refer to the table below.
Willingness. | Would you excuse me? |
Characteristic activity in the past | Every morning,
he would go for a long walk.. |
Contingent use in a conditional sentence | He would
smoke too much if I didn’t stop him. |
Probability | That would be his mother. |
The modal must is probably one that you recognize. It is used to express
obligation in the present time. For example, Cinderella, you must be
back by midnight.
Must is also used to express logical necessity. For example, Officer,
there must be some mistake; I was only going 40 miles per hour, not 60.
