1、Unit 3,Unit 3 Could you please clean your room?,Section A 3 Grammar focus-4c,Revision,根據(jù)所學(xué)內(nèi)容，寫出下列短語(yǔ)。,疊衣服 做菜 用某人的電腦 扔垃圾 鋪床 掃地 熬夜 生某人的氣 帶出去散步,fold ones clothes do the dishes use ones computer take out the rubbish make the bed sweep the floor stay out late be angry with sb. take sb. for a walk,打掃客廳 在上工

2、作 過(guò)來(lái) 做家務(wù) 搭車,clean the living room work on come over do the housework get a ride,閱讀下列句子，觀察問(wèn)句的用法及回答。,Key sentence structures,Could you（please）+ V-原形？ 表示委婉地提出請(qǐng)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

3、 do my homework.,Peter, could you please take out the trash? Sure, Mom. Could you please do the dishes? Sorry, I cant. I have to do my homework.,重難點(diǎn)點(diǎn)評(píng),在表示請(qǐng)求幫助或請(qǐng)求允許的疑問(wèn)句中，常用could代替can，以表示禮貌，委婉或不確定的語(yǔ)氣，而can則不具備這些語(yǔ)氣。這種情況下不能把could看作can的過(guò)去式。以上兩句中用could是為了表示禮貌的請(qǐng)求。表示請(qǐng)求幫助或請(qǐng)求允許時(shí)，除了can, could之外，還可以用may，句子的表達(dá)方式也

4、各有不同，可以用不同的方式來(lái)表示同一個(gè)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(duì)于、句所作允答可以各種各樣，如同意可以說(shuō)Yes或Sure或Certainly，還可說(shuō)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(shuō)Im sorry you cant. 或Im really sorry, but I have to us

5、e it today. 要避免說(shuō)No, you cant. 這樣顯得很不禮貌。否定回答通常用委婉語(yǔ)氣。, Do you mind if I use your car for a day? 對(duì)于句所作回答可以說(shuō)Never mind. /Not at all. 表“不介意”。不能用Yes. /Sure. /Of course. /Certainly.等。無(wú)論肯定還是否定應(yīng)答中，要避免使用could，要用can或may。因?yàn)閼?yīng)答須用確定的語(yǔ)氣。而could在表請(qǐng)求的問(wèn)句中是為了表示禮貌或委婉語(yǔ)氣，用在應(yīng)答中則成了不確定語(yǔ)氣，與情理不符。所以應(yīng)答中不說(shuō)Yes, you could. 或No, you

6、couldnt. 而要說(shuō)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(qǐng)求或提議，其后連接原形動(dòng)詞，比Can you /I？語(yǔ)氣更委婉。類似句型有：,Would you like + sth. / to do sth.? May I + do sth.? Shall we + do sth.? Wou

7、ld 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。,Make up dialogues using the sentences in Grammar Focus with your partner.,A: Could you please take the dog for a walk?

10、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(lái)不屬于自己的東西借來(lái)暫時(shí)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(shí)使用，常與介詞to連用，也可以跟雙賓語(yǔ)。如： Hes going to lend his bike to Tom.
