1. Could you please clean your room? 

Yes, sure. / Sorry, I can’t. I have to do my homework first. 2. Could I please use the car? 

Sure. / Certainly. / Of course.  /  No, you can’t. I have to go out.

在表示请求帮助或请求允许的疑问句中,常用could代替can,以表示礼貌,委婉或不确定的语气,而can则不具备这些语气。这种情况下不能把could看作can的过去式。以上两句中用could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。例:

  Could/Can/May I use your car for a day?

  作允答可以各种各样,

如同意可以说Yes,或Sure或Certainly,还可说Yes, (do) please. 或Of course. (you may/can). 或That’s OK/all right.

如果不同意,可以说I’m sorry you can’t. 或I’m really sorry, but I have to use it today. 要避免说No, you can’t. 这样显得很不礼貌。否定回答通常用委婉语气。

could在表请求的问句中是为了表示礼貌或委婉语气,用在应答中则成了不确定语气,与情理不符。所以应答中不说Yes, you could. 或No, you couldn’t. 而要说Yes, you can. 或Sorry. /No, you can
