Unit 7谈论物品的价格教学重、难点1、会用英语谈论物品颜色、价格及对服装的好恶。 2、掌握购物时的礼貌用语。1、 重点词汇:much,sock,T-shirt,shorts,sweater,trousers,shoe,skirt,dollar,big,small,short,long,woman,need,look,pair,take, ten-thirty, price, buy, sale, sell, clothes.2、 短语归纳:1. how much 多少钱 2. seven dollars 7美元 3. white bag 白色的包4. clothes store 服装店 5. at very good price 以很低的价格 6. for boys 对于男孩子7. shirts in red 红色的裙子 8. twenty-eight dollars 28美元 9. Big Sale!大降价10. twenty yuan 20元 11. a pair of black shoes 一双黑色的鞋子 3、How much is this T-shirt? how much 通常用来对价格进行提问,意为“多少钱”。常构成句式“How much is/are+物品?”,回答用“Its /Theyre+价格”。/ 直接用价格来回答。How much is your sweater? / How much are these trousers?Its 123 dollars./123 dollars. / Theyre 130 yuan.】对价格进行询问时,还可用:Whats the price of ?使用这一句型时,无论被询问的商品是单数还是复数,be动词都用is,不能用are;其答语为Its.价格是Whats the price of the book? Whats the price of these books?Its five yuan . Its ten yuan .】辨析how much和how many表示“多少”,都是对名词的数量进行提问,两者区别如下:how much后接不可数名词,用于提问不可数名词的数量或价格句式:How much + 不可数名词 + 一般疑问句?how many后接可数名词复数,用于提问可数名词的数量句式:How many + 可数名词复数 + 一般疑问句?4、像socks, shoes, trousers, glasses, shorts,等都是成双成对的物品,一般以复数的形式出现。1) 这类名词作主语时,谓语动词一般用复数形式。e.g. How much are these shorts? / How much are these socks? 这双短袜多少钱?2) 若表示“一双,一副,一条”时则要用a pair of,但谓语动词用单数形式。e.g. The pair of trousers is 98 yuan. a pair of / two pairs of socks/shorts (也可以用some, many, these, those等词修饰)5、dollar 可数名词,“美元”,其符号为$,其复数形式为dollars。中国的货币单位是元,其符号为¥,为不可数名词。1) 表价格时,用单词则放在数字之后,用符号则放在数字之前。e.g. 20 dollars =$20 .(货币符号没有复数形式)2) 所有的钱数同时间、距离一样,无论多少,在句中作主语时,谓语动词都用单数形式。e.g. 5,000 dollars is quite a lot of money for me.Five weeks is quite a long time.五周是相当长的一段时间。6、Can I help you? 我能帮您吗? =May I help you ? / What can I do for you? / Is there anything I can do for you?Thank you,I want / Yes,please. Id like / No, thanks. Im just looking around. / Just a look.这一句主要是英语国家里,服务员招呼客户的常用语,以表示客气和礼貌,而不说“What do you want?”。Can I help you?_.I want to buy some T-shorts for my children.A. Yes, please. B. No, thanks. C. It doesnt matter D. Of course I can 7、need “需要”1) 当实义动词时, need + n. / prep. /to do sth. 】构成否定句和疑问句时需借助助动词do/does.e.g. I need a hat./ Does your mother need any help? 2) 当情态动词时,need + v原。】变否定句时要在need 后加not,变疑问句时,要把need提到主语前。e.g. You neednt do it again. / Need he do his homework first?8、How about this one?one,代词,此处用于指代上文提到的sweaters中的一件。 e.g. I have some apples. Do you want one? 】one 和it 均指上文出现过的名词,但其用法不同。 one指代“同名异物”,即指代与前面事物同属一类的事物,并不是指同一个事物。如果指代同类事物中的一些,要用onesit指代“同名同物”,即指代上文出现过的同一事物 e.g. This apple is small. Please give me this one. 这个苹果小,请给我一个大的。 These books are mine. Those ones are lilys. 这些书是我的,那些(书)是莉莉的。 Wheres my pen ? I cant find it.9、look 1)系动词,“看上去,看起来”,+ adj.e.g. You look very healthy. / The teacher looks very happy.2)作不及物动词,“看”,加宾语时要与at连用,即 look at.e.g. Look! Here comes the bus. / Look at the picture, please.10、Ill take it. 我买了。 此句是选好的商品并决定购买时的常用语。如果选定的物品是单数时,说“Ill take it.”;如果选定的物品是复数时,应说“Ill take them.”。1) Ill = I will, will是助动词,表“将要”,用于表示将来发生的动作。2) Take “买”,相当于buy/get/have。在口语中,买东西常用take.e.g. The coat is very cheap. Ill take it.11、Here you are.给你 是把某物递给对方时的常说的一句话。当你购物或借东西时,也常用这句,表示“给你”。 不同情景意义不尽相同。当你乘车到站时,这句话意为“你到站了”。当寻物时,若是自己发现的常说“Here it is.”或“Here they are.”,意为“找到了”。 May I use your dictionary? Mine is at home. _.A. Thanks a lot. B. Id love to C. Youre welcome D. Sure. Here you are.12、clothes n.“衣服”,统指(身上的)各种服装,包括上衣,裤子等。1)它不能直接与数词连用,但可以用these, those,some等词来修饰。2)clothes 本身是复数形式,作主语时,谓语动词总用复数形式。但如果用量词suit来修饰,谓语动词应和suit在单复数形式上保持一致。e.g. This suit of clothes is Jims. / Those suits of clothes are on sale now.13、store 可数名词,“商店”,同义词为stop,store往往指百货商店。 还可做动词,“储存,储备“,e.g. You need to store food.14、buy 及物动词,“买”,反义词为sell(卖)buy sb. sth.=buy sth. for sb.给某人卖某物e.g. I want to buy my father some presents.=I want to buy some presents for my father.15、sell 及物动词,“出售,销售”,Sell sb. sth.=sell sth.to sb.卖某物给某人e.g. They will sell me their books.=They will sell their books to me .他们将要把他们的书卖给我。16、sale n.“出售,销售”,其动词形式sell e.g. The sale of his old house will make him sad.at great sale 在大减价期间 e.g. Come and buy your clothes at our great sale.on sale (正在)出售,减价销售=at a sale e.g.The books are on sale。for sale 待售, e.g. The house is for sale.on sale for 以.价格出售 e.g. The hat is on sale for 8 dollars.17、.at very good prices 以很低(合理)的价格出售。 1)at 以.的价格 price n. “价格、价钱“与介词of 常构成短语:the price of.“.的价格” 2)询问价格且句中有price时,疑问句通常用what ,不用how much; 3)表示价格“高低”时,常用high和low,不用expensive 或 cheap。 e.g. I buy it at a very good price,3 yuan .18、for only +具体价钱 表示某物卖多少钱e.g. These trousers are for seventy yuan . / for only 28 dallars19、in + 颜色 表“穿颜色的”e.g.
