How can you talk to your mother like that? 这里为什么要用can?

can在英语中是情态动词
,后跟动词原形.有三种用法：

can
swim.我会游泳.The
question
is
easy,Ican
answer
it
easily.这个问题简单,我能容易的答出来
.
2.表示请求、允许：Can
I
help
you?有时可以与may
互换.例如：Can/May
I
sit
here?我可以坐这吗?但can多用于口语,而may较正式.
3.表推测.The
book
can

Li's.这本书可能是李的.表推测时与must(一定）相比语气要弱些.例如：The
book

,上面有她的名字.另外,还有固定搭配：can't
help
doing
禁不住做某事
