Couldyou(please)dosth?

1).Couldyoupleasecleanyourroom?

A肯定回答：Yes,Ican.

同义回答Yes,sure./Yes,ofcourse./noproblem

B否定回答：

Sorry,Ican’t.

Ihavetodomyhomework.

2.表示委婉地请求别人允许自己做某事:

CouldIdosth.?1).CouldIgotothemovies?

肯定回答：Yes,youcan./yes,please.Yes,sure.否定回答：No,youcan't./sorry,youcan't/I'mafraidyoucan't.

语法点小结：A:—Couldyouplease+v/notv(动词原形)…?

Yes,Ican.Allright.B：YesSure.No

problem.Certainly.

No,Ican’t…

Ihaveto…B：“No”Sorry,Ican’t…

Ihaveto…3.Could与can的区别Could与can都是情态动词，could是can的过去式。二者都可用于表示请求，但是用法稍有不同:在表示请求帮助或请求允许的疑问句中，我们常用could代替can，以表示礼貌、委婉或不确定的语气，而can则不具有这些语气。这样用时，不能把could看作为can的过去式。A.can表示一般性的请求，语气随便，常用于熟人之间或长辈对辈、上级对下级的场合；

1).Canyou

tellusyourstory,Tony?

B.Could表示有礼貌的请求，语气委婉，常用于非熟人之间或晚辈对长辈、下级对上级的场合
