(you may/can). 或go ahead, please. 或thats ok/all right; 如果不同意，可以说im sorry 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： 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. 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 dont come back too late.e. no, i cant. 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? 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 dont want to do that! its boring!a: ok. then _ you _ do the dishes for me?b: sure, no problem. but _ we go to the movies after that?a: sure. ill finish my homework while you help me with the dishes. then we can go to the movies. step 5 discussi
