情态动词can和could均可以用来提出要求，但could语气较为委婉，客气。
could与can的区别
could与can都是情态动词，could是can的过去式。二者都可用于
表示请求。但是用法稍有不同。
can表示一般性的请求，语气随便，常用于熟人之间或长辈对辈，上级对下级的场合；
Can
you
tell
us
your
story
,
Tony
?
could表示有礼貌的请求，语气委婉，常用于非熟人之间或晚辈对长辈，下级对上级的场合。

you
tell
us
if
it
snows
in
winter
in
Australia
?
Sure
.
Could
you
please
sweep
the
floor?
你能扫一下地吗？
Could
you
please后加
.表示委婉的请求。
