表示请求帮助或请求允许的疑问句中，常用could代替can，表示礼貌、委婉或不确定，而can则不具备这些语气。这时不能把could看作can的过去式。以上两句型中用could是为了表示礼貌的请求CouldI/youplease…？表示一种有礼貌的请求或提议，其后连接原形动词，比Canyou/I…？语气更委婉。类似句型有：Wouldyoulike+sth./todosth.?MayI+dosth.?Wouldyoumind+sth./doingsth.?

What/Howabout+sth./doingsth.?

肯定回答有Sure./Ofcourse./Certainly./OK./Great./Well./Goodidea./Iagree.等。否定回答有Sorry…/No,youcan’t.
