六、金点剖析
1． What can I do for you, Madam? 此句与May/Can I help you? 用法相同。使用范围较广，在不同的场合句意不同：在商店里售货员询问顾客“你要买什么东西？”；在饭店里，服务员询问顾客“你要点什么菜？”； 在图书馆里，图书管理员询问“你要借什么书刊？”。
如：—What can I do for youi? I like some chicken.-May/Can I help you?-I want to borrow an English book.2． I want to buy some clothes for my daughter.Buy sth for sb=buy sb sth 意为“给某人买某物”
如： My mom buys a school bag for me.=My mom buys me a schoolbag.3． How much is it/are they? 多少钱？
（1）how much 用来询问价钱，意为“多少钱”。句子里的be 动词取决于后面的主语（名词或代词），主语为单数时用is,为复数时用are.如：-How much are the books?-They are 29 yuan 【拓展】询问价钱还可用句型 What’s the price of„.? –What’s the price of the 1 jacket?-It’s 100 yuan.【即时演练】按要求改写句子。How much is the phone?(同义句转换)______ _____ ______ ______ the phone?(2)how much 还常用来提问不可数名词的数量。
如：-How much milk do you want?-I want a gla of milk.4.We’ll take it.这里的take 相当于buy, 意为“买下”。在口语中，当选定商品，决定购买时，常说“ I’ll take it.,而不说 I’ ll buy it.Take 原意为“拿走，运走。” take sb(sth)to„把某人（某物）带到某地。
如：I take my little brother to his school.5.Why not try on that pair? Try on ,试穿，试戴。on在此处为副词，故 try on 被称为副词短语，其短语后的宾语为人称代词it/them时，代词须放在动词和副词之间，如：try it/them on;但如果宾语为名词时，它可以放在短语之间，也可以放在短语之后。
如：These shoes are good.You can try them on.Try on these shoes.= Try these shoes on.试试这双鞋。【拓展】pair n 一对，一双，一条„„..如: a pair of pants in pairs 成双成对
如：Students work in pairs.学生们两人一起工作。【即时演练】
I like this red skirt and that pink dre.Can I ____? A try on it B try it on C try on them D try them on 6 Jane, what do you think of this green skirt? What do you think of „.? 相当于 How do you like„? 这个句型常用来询问别人对某人或某物的看法、喜好程度。
如：— What do you think of the movie?-I like it very much.我非常喜欢。
【即时演练】 How do you like the pants?(同义句转换)____ _____ you_____ ______ the pants? 7.Thank you all the same.这句话常常用来表示别人帮你做某事，但是由于某种原因没有做成，你同样要表示感谢。相当于Thank you anyway.如：-Do you know Tian’an Men Square? –Sorry, I don’t know.-Thank you all the same.8 – How many bottles? how many 常用来提问事物的数量，后面应接可数名词的复数形式。
如：-How many students can you see in the picture?-I can see only one.【链接】当提问事物的数量时,how much 接不可数名词，how many 接可数名词复数。

名词是表示人或物的名称的词。它分为可数名词和不可数名词两类。
（1）可数名词有单数和复数两种形式，前面可以用不定冠词a/an修饰。如：a bag 一个包an apple一个苹果 three boxes 三个盒子 some eggs 一些鸡蛋（2）不可数名词
1）不可数名词通常是一些物质类名词、抽象意义的名词及液体、气体、溶液类名词。
如：gla 玻璃 wood 木头 water 水
2）不可数名词一般没有单数和复数形式之分。不能直接用冠词和数次来修饰。3）不可数名词可用little, some, much, any, a lot 等词修饰。若要表示量的多 少时，则需要借助单位名词（即量词）+of来表达。如：two bags of salt two glaes of milk.（3）有些名词有时是可数，有时是不可数。
如：chicken小鸡（可数）鸡肉（不可数）gla 玻璃（不可数）玻璃杯（可数）
