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.StepStep 3 3 GrammarGrammarCould 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 cant. 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 则不具备这复习前面所学动词短语和句型。为语法总结做准备 朗读，寻找语法要点总结语法规4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? 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 Go ahead, please. 或 Thats OK/all right; 如果不同意，可以说 Im so rry 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。 Do you mind if I use your car for a day? 对于句所作回答可以说 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. 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：则5Would 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。 StepStep 4 4 PracticePracticeMake 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 I'm trying not to get it wet.6Note：borrow 和 lendborrow 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：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?
