Could you please_____ _____ ?Could I _____ ? speak slowerhave a sandwich阅读下列句子，观察问句的用法及回答。 Could you（please）+ V-原形？ 表示委婉地提出请求1. Could you please clean your room? Yes, sure./ Of course./ Certainly./All right. 2. Could you please do the dishes? Sorry, I can’t. I have to do my homework. Could I/ we + V-原形？ 表示向别人征询许可—Could I go out tonight, Mom? —Yes, you can. / No, you can’t. 表示请求帮助或请求允许的疑问句中，常用could代替can，表示礼貌，委婉或不确定，而can则不具备这些语气。这时不能把could看作can的过去式。以上两句型中用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，句子的表达方式也有不同，可以用不同的方式来表示同一个概念。例如： ① Could/Can/May I use your car for a day? ② I wonder if I could use your car for a day? 同意可说Yes或Sure或Certainly，还可说Yes, (do) please. 或Of course. (you may/can). 或Go ahead, please. 或That’s OK/all right; 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. 这样不礼貌。否定回答通常用委婉语气。③ Do you mind if I use your car for a day? 作回答可以说Never mind. /Not at all. 表“不介意”。不能用Yes. /Sure. /Of course. /Certainly.等。无论肯定还是否定应答中，要避免使用could，要用can或may。因为应答须用确定的语气。而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’t. —Could I please use your computer? —Sorry, I’m going to work on it now. —Well, could I watch TV? —Yes, you can.Could I/you please …？表示一种有礼貌的请求或提议，其后连接原形动词，比Can you /I…？语气更委婉。类似句型有：Would you like + sth. / to do sth.? May I + do sth.? Shall we + do sth.? Would you mind + sth. /doing sth.? What / How about + sth. /doing sth.? 肯定回答有Sure. /Of course. / Certainly. /OK. /Great. / Well. / Good idea. / I agree. 等。否定回答有Sorry… / No, you can’t. 等。 Make up dialogues using the sentences in Grammar Focus with your partner.A: Could you ple ... ...
