Unit 3
Could you please clean your room?
Could you please后加动词原形表示委婉的请求。
肯定回答常用Sure/Certainly/Of course.
否定回答常用Sorry, I can’t.
一般不用No回答,用No显得态度生硬,不礼貌。
注:could是情态动词can的过去式,但在本句中Could you do…?不表示过去,而是用以表示礼貌、委婉或不确定的语气。
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。
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。
e.g. —Could you tell us if it snows in winter in Australia?
—Sure.
can表示一般性的请求,语气随便,常用于熟人之间或长辈对晚辈,上级对下级的场合;
e.g. Can you tell us your story, Tony?
Tony, could you please help out with a few things?
e.g. I sometimes help out in the kitchen.
