When are you starting?你什么时候动身? Don’t worry.The train is arriving here soon.别着急,火车马上就到了。表示将来的现在进行时除了用于位移动词外,亦可用于某些非位移动词。如:My uncle is meeting us tomorrow.我叔叔明天会见我们。She is buying a new bike soon.她不久将买一辆新自行车。四.交际用语: 谈论不同国家英语的不同点并了解交际中的身体语言 1.I can’t follow you.Can you speak more slowly, please? 2.Oh, it sounds interesting.3.If you want to succeed in making yourself understood, you need to know some of these differences 4.---What’s up?---The foreigner is asking for a ride.5.Generally speaking, American English is different from British English in pronunciation and spelling.Unit 3 Topic 3

Countable nouns and uncountable nous 六．其他 学习辅音音标 /h/ /r/ /w/ /j/ 七．金点剖析

1.Help yourselves！请随便（吃/喝）。help oneself to„.意为“请随便吃/喝„..”,是招待客人常用的交际用语。后可接可数名词复数，也可接不可数名词。当只有一位客人时，用yourself;当有多位客人时，用yourselves.如：Help yourself to some bananas.请吃些香蕉吧。Kids, help yourselves to some pizza.孩子们，请吃些比萨饼吧。【即时演练】1.Help____ to some fish, dear friends.2.Kate, help____to some cakes.2.I’d like some chicken.我想吃一些肉。I’d like 是I would like 的简写形式。Would like 意为“想要„..，愿意„.”,常用来表示婉转的请求以及征求对方的意见，相当于want,但比 want 语气委婉。（1）would like 后面跟名词或代词。如：I’d like some cakes=I want some cakes.我想要一些蛋糕。Would you like something to eat? 你想吃点东西吗？（2）would like 后跟动词时，用动词不定式形式（不定式由to+动词原形构成），即 would like to do sth, 意为“想要做某事”。如：I’d like to visit my grandparents after school.放学后我想去看望我的祖父母。

Would you like to come to my home for supper.? 你愿意到我家来吃晚饭吗？（3）would like sb to do sth 意为“想要某人做某事”。如：-What would you like me to do? 你想要我做什么？-I’d like you to help me with my English。我想要你帮我学英语。（4）Would you like +n? 的回答用Yes,please.或No, thanks.如：-Would you like some bread? 你想要点面包吗？-Yes,please./No,thanks.好的，请把。/不，谢谢。

3What about you, Jane? 简，你呢？（1）What about +sb?这一句型用来询问对方或第三者是否也具有上文提到过的情况、观点等。如：I want to drink milk.What about you? 我想喝牛奶，你呢？ I like English.What about Tom? 我喜欢英语，汤姆呢？（2）what about+ 名词、代词或动名词，表示说话人的建议或用来征询对方的意见。如：What about this English book?这本英语书怎么样？What about something to eat/drink? 要不要吃、喝些什么？ What about visiting the Great Wall? 去参观长城怎么样？【拓展】 What about „?相当于 How about„..?如：What about havig a cup of tea=How about having a cup of 1 tea? 4What do you usually have for breakfast，Michael? 迈克尔，你早餐通常吃什么？一般情况下，表示一日三餐的名词前不加冠词。For 在句子中作介词，表示“为了„.”, for+breakfast/lunch/supper 为固定搭配。如：I’d like some rice for breakfast.我早餐想吃点米饭。What would you like for lunch? 你午餐想吃点什么？

5May I take your order,sir? 先生，你可以点菜了吗？（1）这是餐馆服务员询问客人是否准备点菜的常用语。take one’s order 意为“记下顾客点的饭菜 ”。服务员问顾客想吃点什么，也可以说May/Can I help you ?或 What can I do for you?(2)意为“先生，阁下”，用于对顾客，上级或陌生男性的尊称。

6.-Would you like something to drink? 你想喝点东西吗？-Yes，a glass of apple juice,please.是的，请来一杯苹果汁。在英语中名词分为可数名词和不可数名词。可数名词有单数和复数形式，不可数名词没有单复数形式变化，如想表示复数含义，可在不可数名词前加some,any或表示数量的短语。如：some meat 一些肉 any milk 一些牛奶 a cup of tea 一杯茶 a bag of rice 一袋大米 a glass of water 一杯水 two bottles of orange juice 两瓶橙汁 three pieces of bread 三片面包 a piece of news 一则新闻 Wait a moment, lease.请稍等片刻。Moment n 片刻，瞬间。如：just a moment=wait a moment 稍等片刻【拓展】 at the moment 此刻 in a moment 立即，马上 for the moment 暂时，目前 Let me see.让我看看/想想。这是口语中常用的句型。Let sb do sth 意为“让某人做某事。”常用于提出建议。肯定回答一般用OK./All right.否定回答一般用 sorry,I„.。Let’s =Let us,是这一结构的特例。如：Let’s visit the Great Wall 让我们去参观长城吧。Let Tom help you.让汤姆帮助你。

9.Why not have some fish and eggs?为什么不来一些鱼肉和鸡蛋呢？Why not do sth?意为“为什么不„.?何不„?表示说话人的建议或劝说。其同义句型是Why don’t you/we do sth? 如：Why not give the letter to Maria?=Why don’t we give the letter to Maria? 为什么我们不把那封信给玛利亚呢？ Why not study English with us? =Why don’t you study English with us? 你为什么不跟我们一起学英语呢？

10.Here you are.给你 当别人向你要东西，你答应给别人并在递东西的同时说这句话。注意此句与 You are here.的区别。后面的意思是“你在这儿”。如：-Can I have your pen? 我可以用你的钢笔吗？-Here you are.给你。Kate，you’re here.凯特，你在这儿。11.They are all kind to me.他们都对我很友好。be kind to sb 意为“对某人很友善。”此时kind 与 friendly(友好的)可互换。如：Our English teacher is friendly to us.我们的英语老师对我们很友善。
