教学过程
Step 1 Revision

Step 2 Presentation
阅读下列句子,观察问句的用法及回答。
---Could I go out for dinner with my friends?
---Sure, that should be OK.
---Could we get something to drink after the movie?
---No, you can’t. You have a basketball game tomorrow.
---Could you please take the dog for a walk?
---OK, but I want to watch one show first.
---Could you please take out the rubbish?
---Yes, sure.
Step 3 Grammar
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.
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,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.(不够委婉,很少用)等。
