1. Using “can”/ “could” to talk about ability.
We use “can” to talk about present ability.
We use “could” to talk about ability in the past.e.g.
I can (cannot /can’t ) swim.
He could (could not /couldn’t ) dance in the past. Grammar 2.Using ‘can’、‘could’ and ‘may’ to talk about permission1）can 与 could
can 常用于口语中，表示非正式的请求,请求对象一般是家人或朋友。e.g.
— Can I borrow your bike, Millie?
— Of course.
— Can I have some milk, Mum?
— Yes, you can.
could是can的过去式。在口语中，could常用来代替can向对方更委婉地提出请求，用法上比can正式，可以用于向老师或长辈提出请求，这时could不表示过去，回答一般还是用can。e.g.
— Could I use your computer, please?
— Yes, you can.
— Could I hand in our homework later, Mr Wang?
— No, you can’t.
2)may
may也可以用来征求对方意见，意为“可以”，相当于could，用法也比can更正式，更礼貌，一般用于向陌生人或所尊敬的人请求许可。e.g.
— May I ask you a question?
— Yes, please.
— May I come in, Miss Li?
— No, you may not.
