【语法聚焦】
表示请求、允许、许可
表示允许时用can, could, may, might表达。它们没有时态上的差别，只是could比can, might比may语气上要客气。（用can或could表示“许可”，虽然很普通，但在正式、庄重的场合用may。）
例如：
●A: Could I borrow your dictionary? 劳驾，我可以借你的字典用用吗？
B: Yes, of course (you can). 当然可以。
●Can表示“允许、许可”时，和may的意思相近，即can=may.
此时的否定式是can’t (=must not)
●Could/Can you please tell me how to get to the post office?
劳驾，您能告诉我怎么去邮局吗？
●Mr Li asked me whether I could go with him.
李先生问我是否可以和他一起去。
(此句中的could不能用can代替。)
表示请求时还可以用句型：Will/Would you …? 请（为我）……好吗？
该句型用于请求对方做某事。 Would you…?比较客气。语气比Will you…?要委婉。
例如：
●Will you pass me the spoon? 请把勺子递给我好吗？
●Would you lend me your dictionary? 请借你的词典用一下好吗？
答句为：
Yes, I will. 是的，可以。
Sure. 当然了。
All right. 好啊。
Certainly. 当然可以。
Yes, please. 好的，可以。
No, I won’t. 不，不行。
I’m sorry. I can’t. 对不起， 不行。
No, thank you. 不了，谢谢。
●Shall I …? 我要…吗？
Shall we…? 我们一起 …好吗？
Shall we…? 与Let’s…. 意思上很相近。
Shall I carry it for you? 我来帮你搬它好吗？
Yes, please./ Yes, thank you. 好吧。/好吧，谢谢。
Shall we sing a song? 我们唱一支歌好吗？
No, let’s not. 不， 别唱了。
