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 /can not) swim. He could (couldn’t /could not) dance in the past. can/could区别?Using ‘can’, ‘could’, ‘may’ and to talk about permission(许可)1. 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, Simon?
西蒙, 我可以借一下你的自行车吗?
— Of course.
当然可以。在口语中,could常用来代替can向对方更委婉、有礼貌地提出请求,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,但是否定回答只能用can’t,不能用couldn’t。e.g.
— Could I use your computer, please?
请问,我可以用一下你的电脑吗?
— Yes, you can/could. 可以。

— No, you can’t. 不,不行。2. may
may也可以用来征求对方意见,意为“可以”,用法比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.
