Question：Can还可以用于请求吧？ Answer：是的。今天我们继续学习情态动词（II） 用于请求，提供和邀请的can,could, may, would Reading： In the library: Chen Ling: Can I have the books on history please? And could I sit inside the reading room to read them? Library assistant : Yes, of course. The books on the ninth shelf are the books on history. Chen Ling: May I have the list of the books? And would you introduce some new books to me? Library assistant: Certainly. You can get the list of the books on this computer. Here is the introduction of the new books on history. (More readers come into the library at the moment) But can you go inside the reading room to get the details? Chen Ling: Oh, yes. Thank you very much. But if I want to borrow some books home, how many at a time and how long may I keep them? Library assistant: Two a time, and two weeks. Chen Ling: Could you give me a little longer? Library assistant: I’m sorry. But if you want to keep them longer, you can come and renew them. I.用于请求的can, could, may, would （1） 用can, could和may可以表示要东西或请求允许： Can I have the books on history please? Could I sit inside the reading room to read them? May I have the list of books? Could 比can 稍微客气一些。 May 比could 更有礼貌也更正式， 但不如could 用得普遍。 注意：在表示请求时， 从不用Would …I/we? （不说Would I have the books on history?） 应该说：Can I/ Could I/May I have the books on history? （2） 用can, could 和would 可以表示请某人做某事： Can you go inside the reading room to get the details? Could you give me a bit longer? Would you introduce some new books to me? Could I/you比Can I/you稍微客气一些。 Would you 比 Could you 更有礼貌也更正式，Can you 则不太普遍。 II. 用can, could, may 表示要什么和请求允许。 In the reading room Chen Ling: Can I smoke? Reading room assistant: No, I’m afraid you can’t. This is a non-smoking section. Chen Ling: Could I sit in this seat, please? Reader A: I’m sorry, but this seat is taken. And you can sit over there. Chen Ling : Thank you. May I use your pen, please? Reader B: Certainly. Chen Ling:Thank you very much. Reader B: That’s all right. （1） 用can,could 或may 请求允许： Can I smoke? Could I sit here? May I sit I this seat? Could 比Can稍微礼貌一些，may 比could 稍微礼貌一些。 （2） 在应答表示允许时，用can, may也可以用，但是很正规，不常用，一般不用could: Can I smoke? No, I’m afraid you can’t. Could I sit here? Yes, you can. III. Can 和may 表示提供， would like 表示提供和邀请 During the time when Chen Ling is reading in the reading room, Reader B suddenly felt sick. Chen Ling: Can I help you? Reader B: Thank you. I just want to have a rest. Chen Ling: May I send for a doctor here? Reader B: Oh, no. I think I’ll be better after a little while. Chen Ling: Would you like some water? Reader B: Yes, please. Chen Ling: Would you like to sit outside the reading room? Would you like me to support you out? Reader B: Yes, that would be nice. Thank you. （1） 当表示提供做某事时用Can I/ May I…如： Can I help you?—May I send for a doctor here? Can I 不如May I 正规， 但更常用。 （2） 用would like 表示提供什么或提供做什么： Would you like more water? Would you like me to support you out? （3） 用 would like 来请某人做什么： Would you like to sit outside the reading room? 小练习： Fill in the blanks： A: 1_____ I help you? B: Thank you.
