4、ight.2.Couldyoupleasedothedishes?Sorry,Ican’t.Ihavetodomyhomework.在表示请求帮助或请求允许的疑问句中,常用could代替can,以表示礼貌,委婉或不确定的语气,而can则不具备这些语气。这种情况下不能把could看作can的过去式。以上两句中用could是为了表示礼貌的请求。表示请求帮助或请求允许时,除了can,could之外,还可以用may,句子的表达方式也各有不同,可以用不同的方式来表示同一个概念。例:①Could/Can/MayIuseyourcarforaday?②IwonderifIcoulduseyourc

7、I/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.?Shallwe+dosth.?Wouldyoumind+sth./doingsth.?What/Howabout+sth./doingsth.?肯定回答有Sure./Ofcourse./Certainly./OK./Great./Well./Goodidea./I
