举例
Unit 3 Could you please clean your room?
Section A 3 (Grammar focus-4c)
Step 1 Revision
根据所学内容，写出下列短语。
fold one’s clothes, do the dishes, use one’s computer, take out the rubbish
make the bed, sweep the floor, stay out late, be angry with sb., take sb. for a walk
clean the living room, work on, come over, do the housework, get a ride
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，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：
① Could/Can/May I use your car for a day?
② I wonder if I could use your car for a day?
对于①、②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Go ahead, please. 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。
③ Do you mind if I use your car for a day?
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 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。
Step 4 Practice
Make up dialogues using the sentences in Grammar Focus with your partner.
A: Could you please take the dog for a walk?
B: OK, but I want to watch one show first.
4a Write R for requests and P for permission. Then match each one with the correct response.
1. ___ Could I hang out with my friends after the movies?
出去玩
2. ___ Could you please pass me the salt?
3. ___ Could I borrow that book?
4. ___ Could you help me do the dishes?
5. ___ Could you lend me some money?
a. Yes, here you are.
b. Hmm. How much do you need?
c. Yes, sure. No problem. I finished reading it last night.
d. Yes, but don’t come back too late.
e. No, I can’t. I cut my finger and I'm trying not to get it wet.
Note：
borrow和lend
borrow和lend都有“借”的意思，但它们的含义和用法有所不同。
★ borrow表示“借入”，即把本来不属于自己的东西借来暂时使用，常与介词from连用。如：
You can borrow a book from the library.
★ lend表示“借出”，即把属于自己的东西借给别人暂时使用，常与介词to连用，也可以跟双宾语。如：
He’s going to lend his bike to Tom.
You mustn’t lend others my pen.
4b Fill in the blanks in the conversation.
A: I hate to ____ chores.
B: Well, I hate some chores too, but I like other chores.
A: Really? Great! _____ I ask you to ____ me with some chores then?
B: What do you need help with?
A: ______ you please _____ my clothes for me?
B: I don’t want to do that! It’s boring!
A: OK. Then ______ you ______ do the dishes for me?
B: Sure, no problem. But _____ we go to the movies after that?
A: Sure. I’ll finish my homework while you help me with the dishes. Then we can go to the movies.

If we are having a camping trip, what should we do before the trip?
