2、oor, 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 根据所学过的课文从中找出对应的语法点并解析。 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

3、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

4、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 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

5、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.

6、 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. /doi

7、ng 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 Practice Make up dialogues using the sentences in Grammar Focus with your partner.

10、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.
