情态动词里的will、would、could都可以表达礼貌地提出问题，它们之间有什么区别吗

【1】used for asking sb to do sth （烦劳别人做事时用）

Will you send this letter for me, please?

请你替我把这封信寄出去行吗？

【2】used in polite offers or invitations （客气地建议或邀请）

Would you like a sandwich?您来一个三明治好吗？

Would you have dinner with me on Friday?请你星期五和我一起用餐好吗？

备注：would 语气比will更加客气委婉。

【3】can:You use can in questions in order to make polite requests.

Can I have a look at that?我能不能看一眼那个?

Can you please help?.请你帮个忙好吗?

【4】Could used to politely ask sb to do sth for you （礼貌地请求别人做事）能，可以

Could you babysit for us on Friday?你星期五帮我们看一下孩子好吗？

备注：could 语气比can更加客气委婉。
