Section A 3 (Grammar focus-4c)Step 1 Revision根據(jù)所學(xué)內(nèi)容，寫出下列短語。fold ones clothes, do the dishes, use ones computer, take out the rubbishmake the bed, sweep the floor, stay out late, be angry with sb., take sb. for a walkclean the living room, work on, come over, do the housework, get a rideStep 2 Presentation 閱讀下列句子，觀察問句的用法及回答。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 cant. 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 GrammarCould you（please）+ V-原形？表示委婉地提出請求1. Could you please clean your room? Yes, sure. / Of course./ Certainly./All right.2. Could you please do the dishes? Sorry, I cant. I have to do my homework.在表示請求幫助或請求允許的疑問句中，常用could代替can，以表示禮貌，委婉或不確定的語氣，而can則不具備這些語氣。這種情況下不能把could看作can的過去式。以上兩句中用could是為了表示禮貌的請求。表示請求幫助或請求允許時，除了can, could之外，還可以用may，句子的表達(dá)方式也各有不同，可以用不同的方式來表示同一個概念。例： Could/Can/May I use your car for a day? I wonder if I could use your car for a day? 對于、句所作允答可以各種各樣，如同意可以說Yes或Sure或Certainly，還可說Yes, (do) please. 或Of course. (you may/can). 或Go ahead, please. 或Thats OK/all right; 如果不同意，可以說Im sorry you cant. 或Im really sorry, but I have to use it today. 要避免說No, you cant. 這樣顯得很不禮貌。否定回答通常用委婉語氣。 Do you mind if I use your car for a day? 對于句所作回答可以說Never mind. /Not at all. 表“不介意”。不能用Yes. /Sure. /Of course. /Certainly.等。無論肯定還是否定應(yīng)答中，要避免使用could，要用can或may。因為應(yīng)答須用確定的語氣。而could在表請求的問句中是為了表示禮貌或委婉語氣，用在應(yīng)答中則成了不確定語氣，與情理不符。所以應(yīng)答中不說Yes, you could. 或No, you couldnt. 而要說Yes, you can. 或Sorry. /No, you cant. Could I please use your computer? Sorry, Im going to work on it now. Well, could I watch TV? Yes, you can. Could I/you please ？表示一種有禮貌的請求或提議，其后連接原形動詞，比Can you /I？語氣更委婉。類似句型有： 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 cant. 等。 Step 4 PracticeMake 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.

I cut my finger and Im trying not to get it wet.Note：borrow和lendborrow和lend都有“借”的意思，但它們的含義和用法有所不同。 borrow表示“借入”，即把本來不屬于自己的東西借來暫時使用，常與介詞from連用。如：You can borrow a book from the library. lend表示“借出”，即把屬于自己的東西借給別人暫時使用，常與介詞to連用，也可以跟雙賓語。如：Hes going to lend his bike to Tom. You mustnt 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?
