Make conversation about the chores in 1a.2.Could you please ？用法提示检测Step6 点拨提升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? I wonder if I could use your car for a day? Do you mind if I use your car for a day?对于、句所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Thats OK/all right. 如果不同意，可以说Im sorry you cant. 或Im really sorry, but I have to use it today. 要避免说No, you cant. 这样显得很不礼貌。否定回答通常用委婉语气。对于句（3）所作回答可以说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 couldnt. 而要说Yes, you can. 或Sorry. /No, you cant.Step7达标检测1、 根据句意、汉语意思和首字母提示完成句子。1.
