Using “can”/ “culd” t talk abut ability.1. We use “can” t talk abut present ability. We use “culd” t talk abut ability in the past.
e.g. I can (cannt /can’t /can nt) swim. What abut yu? He culd (culdn’t /culd nt) dance in the past. What abut yu?
— Can I brrw yur bike, Millie?— Yes, yu can. Here yu are.— Culd I smke here?— Srry, I’m afraid yu can’t.— May I use yur mbile phne?— Of curse yu may.
Using ‘can’, ‘culd’, ‘may’ and t talk abut permissin
1. can 与 culd 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 brrw yur bike, Simn? 西蒙, 我可以借一下你的自行车吗？ — Of curse. 当然可以。
— Can I have sme milk, Mum? 妈妈，我可以喝点牛奶吗？ — Yes, yu can. 好的。
culd是can的过去式。在口语中，culd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culd不表示过去，回答一般还是用can。
e.g.— Culd I use yur cmputer, please? 请问，我可以用一下你的电脑吗？ — Yes, yu can. 可以。— Culd I hand in ur hmewrk later, Mr Lin? 林老师，我可以稍后交作业吗？ — N, yu can’t. 不，不行。
2. may may也可以用来征求对方意见，意为“可以”，相当于culd，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 yu a questin? 我可以问你一个问题吗？ — Yes, please. 可以，请问。— May I cme in, Mr Wu? 吴老师，我可以进来吗？ — N, yu may nt. 不行。
(1) can用于同学，同辈之间请求

(2)culd用于向长辈，老师，陌生人有礼貌的请求
(3)may在正式场合，很有礼貌
