    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. . 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 【查看更多】
