aboutpermission

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。

—CanIborrowyourbike,Millie?

—Ofcourse.

—CanIhavesomemilk,Mum?

—Yes,youcan.

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。

—CouldIuseyourcomputer,please?

—Yes,youcan.

—CouldIhandinourhomeworklater,MrWang?—No,youcant.

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。

—MayIaskyouaquestion?

—Yes,please.

—MayIcomein,MissLi?

—No,youmaynot.
