12、ldyoupleasetakeoutthetrash?Sure,Mom.Couldyoupleasedothedishes?Sorry,Icant.Ihavetodomyhomework.(1)在表示請求幫助或請求允許的疑問句中，常用could代替can，以表示禮貌，委婉或不確定的語氣，而can則不具備這些語氣。這種情況下不能把could看作can的過去式。以上兩句中用could是為了表示禮貌的請求。表示請求幫助或請求允許時，除了can,could之外，還可以用may，句子的表達方式也各有不同，可以用不同的方式來表示同一個概念。例:Could/Can/MayIuseyourcarforaday

13、?對于該句型的回答：如同意可以說Yes，或Sure或Certainly，還可說Yes,(do)please.或Ofcourse.(youmay/can).或Goahead,please.或ThatsOK/allright.如果不同意，可以說Imsorryyoucant.或Imreallysorry,butIhavetouseittoday.要避免說No,youcant.這樣顯得很不禮貌。否定回答通常用委婉語氣。DoyoumindifIuseyourcarforaday?對于該句型的回答：所作回答可以說Nevermind./Notatall.表不介意。不能用Yes./Sure./Ofcourse

14、./Certainly.等。無論肯定還是否定應答中，要避免使用could，要用can或may。因為應答須用確定的語氣。而could在表請求的問句中是為了表示禮貌或委婉語氣，用在應答中則成了不確定語氣，與情理不符。所以應答中不說Yes,youcould.或No,youcouldnt.而要說Yes,youcan.或Sorry./No,youcant.單元課堂練習：一、根據(jù)句意及首字母提示完成單詞。1.Myfriendoftenb_mypen.Butheneverreturns(歸還)it.2.TomorrowImgoingtohaveaparty.Idliketoi_myfriendstoit.3
