10、m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?②IwonderifIcoulduseyourcarforaday?对于①、②句所作允答可以各种各样,如同意可以说Yes或Sure或Certain
11、ly,还可说Yes,(do)please.或Ofcourse.(youmay/can).或Goahead,please.或That’sOK/allright;如果不同意,可以说I’msorryyoucan’t.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。③DoyoumindifIuseyourcarforaday?对于句③所作回答可以说Nevermind./Notatall.表“不介意”。不能用Yes./Sure./Ofcourse./Certainly.
12、等。无论肯定还是否定应答中,要避免使用could,要用can或may。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.—CouldIpleaseuseyourcomputer?—Sorry,I’mgoingtoworkonitnow.—Well,couldIwatchTV?—Yes,youcan.CouldI/youplease…?表示一种有礼貌的请求
