7、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 则不具备这些功能。这种情况下不能把 could 看作 can 的过去式。以上两句中用 could 都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。 (1)could/can/may i use your car for a day?(2)i wonder if i could use your car for a day.对于(1)、(2)句的答语,同意可以说“yes.”/“sure.”/“c

8、ertainly.”/“yes, (do) please.”/“of course (youcan).”/“go ahead, please.”; 如果不同意,可以说“im sorry you can t.”/“im really sorry, but ihave to use it today.”,要避免说“no, you cant.”,这样显得很不礼貌。否定回答通常用委婉的语 气。(3)do you mind if i use your car for a day?对于句 (3) 的答语 , 可以说 “of course not./not at all.” 表示 “ 不介意 ” 。不能用
