INTRODUCTION
The modal auxiliaries in English
are : can, could, had better, may, might, must, ought to, shall, should, will,
would
Modal auxiliaries generally
express a speaker’s attitudes,or
“moods".For example, modals can express that speaker fells
something is necessary,advisable,permissible,possible, or probable; and,in
addition,they can convey the strength of these attitudes.
Each modal has more than one
meaning or use. ( see chart 2-23 )

Modals do

INCORRECT : He
cans do it.
Modals are
followed immediately by the simple form of a verb.
CORRECT : He

INCORRECT :
He can to do it./He can does it./He can did it.
The only
exception is Ought, which is followed by an infinitive ( to + the simple
form of a verb ).
CORRECT :
She ought
to go to the meeting.
In (b) is a
list of some common expressions whose meaning are similar to those of some of
the modal auxiliaries.For example, be able to is similar to can;
be going to is similar to will.
An
infinitive ( to + the simple form of a verb ) is used in these similar
expressions.
POLITE
REQUEST WITH “I” AS THE SUBJECT
MAY I
>
(a) May I (please) borrow your pen?
COULD I > (b) Could I borrow
your pen (please)?
CAN I > (c) Can I borrow you pen?
May I
and Could
I are used to request Permission.They are equally polite.* Note in (b):
In a polite request, could has a present or future
meaning, not a past meaning.
Can I
is used informally to request permission,especially if the speaker is talking
to someone s/he knows fairly well.Can I is ussualy not considered as
polite as may I or Could I.
Often the response to a polite
request consist of an action, a nod or shake of the head, or a simple “uh’huh”.
Typical responses: certainly.Yes, certainly.Of course.Yes, Of course.Sure.(Informal)
POLITE
REQUEST WITH “YOU” AS THE SUBJECT

WILL
YOU >
(b) Will you (please) pass the salt?
COULD YOU >
(c) Could you pass the salt?
CAN YOU >
(d) Can you pass the salt?
The meaning of would
you and will you in a polite request is the same.Would you is more common
and is often considered more polite.The degree of politeness,however,is often
determined by the speaker’s tone of voice.
Basically, could you and would
you have the same meaning.The difference is slight:
Would you = Do you want to do this please?
Could you = Do you want to do this please, and is it
possible for you to do this?
Could you and would you are equally polite.
Can you
is often used informally.It usually sounds less polite than could
you or would you.
A person usually responds in the
affirmative to a polite request.If a negative response is necessary, a person
might begin by saying, “ I’d like to, but …” (e.g., “ I’d like to pass the
salt, but I can’t reach it.I’ll ask Tom to pass it to you.”).
