 1.    In a statement, we use can, could, may or might in this way:

Subject + can, could, may or might + base form of main verb / the verb ‘to be’

Example:             You may take a week’s leave.

                             Hoe Boon might be the next head prefect.

2.    In a question, we use can, could, may or might at the beginning in this way:

Can, could, May or might + Subject + base form of main verb / the verb ‘to be’

Example:             Can animals think?

                             Could you be more patient with him?

3.    We use could and might to express the possibility of an action in the past in this way:

Subject + could / might + have + past participle form of main verb / the verb ‘to be’

Example:

Can / could you pass me the salt and pepper?

Example:

Example:

(Definite Possibility)

We may hold a farewell party for her this Saturday.

(Slight Possibility)

Could is used instead of can to that the speaker is more hesitant or unsure.

Might is used instead of May to indicate a less likely possibility.

 

Example:

Nowadays, many young children can use computer.

Could is used as the past tense of can to refer to the ability to do something in the past.
