3、e your bedinvite sb to a place take sb. for a walkplay with sb.give sb sth.=give sth to sbtake care of= look after 【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

4、, 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cant (=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

5、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 wont. 不，不行。Im sorry. I cant.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Lets. 意思上很相

6、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, lets not. 不， 别唱了。 【能力测试】 一. 选择填空1. A: Could you please sweep the floor? B: _.
