的答语一般都用can，而不用could。②情态动词can和could除了表示提出请求和征求许可之外，还

可以表示能力，意为“能；会”，此时could是can的过去式，

只用于一般过去时。妙指津（3）其他用法GrammarFocus③在提出礼貌的请求时，可以在主语后加please，显得更加礼貌和

客气。please还可以放在句尾，其前用逗号与前面的内容隔开。④其他常见的表示委婉请求或征求许可的句型：Will/Wouldyoupleasedo...?请你做……好吗？Wouldyoumind(not)doing...?你介意（不）做……吗？MayI…?我可以……吗？妙指津—Couldyoupleasesweepthefloor,Daming?—________I’mbusycooking.A.Yes,sure. B.Sorry,Ican’t. C.Yes,please.B

典例yes,

典例can可以；must必须；should应该。根据答语“Ofcourseyoucan.”可知，此处应用情态动词can表示征求许可，故选A。点拨—________Itakephotoshere？—Sorry,youcan’t.It’snotallowed(允许)inthemuseum.A.Must B.Need C.Can 句意：——我可以在这里拍照吗？——对不起，你不能。博物馆内不允许拍照。根据答语中的“Sorry,youcan’t.”可知，问句应用can表示征求许可。故选C。C点拨

典例Couldyoupleasedothedishes?(做否定回答)____________,I’mafraidI________.对于“Couldyouplease...?”这种表示请求的句型，否定回答通常用“Sorry”或“No”，然后加上“I’mafraidIcan’t”，表示“我恐怕不能”。所以答案是No/Sorry,I’mafraidIcan’t。No/Sorry点拨
