请你……好吗?这里的could 不是表示一般的过去式, 而是用来表示委婉地提出请求。 Could you please do sth?
1. could表示请求，语气委婉，显得有礼貌
Could you please clean your room?

肯定回答：Yes, I can.
是的，我可以。
Yes, sure. / Yes, of course.
否定回答：
Sorry, I can’t. I have to do my homework.
对不起，我不得不做作业。 2. could表示请求许可，希望得到允许。
Could I go to the movies?
我能去看电影吗？
肯定回答：Yes, you can.
Yes, sure.
当然可以。

不，不行。 Now make sentences using could and the following phrases.
（1）go to the movies 去看电影
（2）stay out late 在外面待得很晚
（3）use the car 使用汽车
（4）get a ride 去骑车
（5）use your computer 使用你的电脑

could与can都是情态动词，could是can的过去式。二者都可用于表示请求，但是用法稍有不同。
can表示一般性的请求，语气随便，常用于熟人之间或长辈对晚辈、上级对下级的场合；
Can you tell us your story, Tony ?
你能给我们讲讲你的故事吗，Tony？ could表示有礼貌的请求，语气委婉，常用于非熟人之间或晚辈对长辈、下级对上级的场合。

Australia?
请告诉我们，澳大利亚冬天下雪吗？
—Sure.
当然可以。—Excuse me, could you help me carry the heavy box?
— _______.
A. Yes, I could B. With pleasure
C. It doesn’t matter D. Don’t mention it【点拨】选B。Could you ...? 表示客气地征求意见或请求许可的询问方式，不能用could 回答。with pleasure 表示同意，意为“乐意效劳；愿意帮助”。C、D是对感谢的回答，不符合语境。Could you please …? —Could you please …？ 4aWrite R for requests and P for permissions. Then match each one with the correct response.1. ___ Could I hang out with my friends after the movie?

?May I borrow your bike?
我可以借用你的自行车吗？
Could you _______ your dictionary to me?
A. borrow B. lend
C. keep D. use【点拨】选B。句意为：你能借给我你的字典吗？对主语“你”来说是借出，lend“借出”，lend sth. to sb. “把某物借给某人”, 其反义词是“borrow”。borrow和lend都可译为“借”，但用法不同。
（1）borrow “借，借入；借用”，从主语的角度讲，指“借入”或“借用他人的东西供自己使用”。常用结构为：borrow sth. from sb. 或borrow one’s sth. 意为“向某人借某物”。 borrow / lend（2）lend “借出；借给”，从主语的角度讲，表示把自己的东西“借出”给别人使用。常用结构为：lend sb. sth. 或lend sth. to sb. 意为“借给某人某物”。
（3）borrow和lend均为非延续性动词，若表达借某物多长时间时，不能用borrow 或lend, 而要用keep, 意为“保存；保留”。 用borrow或lend的正确形式填空：
1. He _________ a book from me, and never
returned it.
2. Can I _________ your bicycle?
3. Joe ________ this car to us for the weekend.
