4、—Peter,couldyoupleasetakeoutthetrash?—Sure,Mom.一Couldyoupleasedothedishes?一Sorry,Ican'1.1havetodomyhomework.(1)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：Could/Can/
5、MayIuseyourcarforaday?对于该句型的回答：如同意可以说Yes或Sure或Certainly还可说Yes,(do)please.或0fcourse,(youmay/can).或Goahead,please.或That'sOK/allright.如果不同意，可以说I'msorryyoucanzt.或I'mreallysorry,butIhavetouseittoday.要避免说No,youcan't.这样显得很不礼貌。否定回答通常用委婉语气。DoyoumindifIuseyourcarforaday?对于该句型的回答：所作回答可以说Nevermind./Notat
6、all.表不介意。不能用Yes./Sure./Ofcourse./Certainly.等。无论肯走还是否定应答中，要避免使用could,要用can或mayo因为应答须用确定的语气。而could在表请求的问句中是为了表示礼貌或委婉语气,用在应答中则成了不确定语气，与情理不符。所以应答中不说Yes,youcould.或No,youcouldn't.而要说Yes,youcan.或Sorry./No,youcan't.高频考点【实战模拟】单词拼写1.一Couldyoupleasesthefloor?一Yes,sure.2.—Couldyoupleasedothed?一Sorry,1can
