Read the conversation first and complete the conversation.2. 指导：首先，快速阅读对话一遍，明确自己售货员的身份，可知第一句话应为“Can I help you?”。然后，读对话，通过对话中谈到的衣物的颜色或价格等信息来确定是何衣物；或通过所谈到的衣物来填写其颜色或价格。如在女孩购物的情境中，根据所谈到these red and purple one，再与。短文中的“We have skirt in red and purple”信息相对应，可知女孩是想买短裙，价格是$20。男孩谈到需要一双棕色的某物上学穿，再由下文知其仅是28美元，回顾短文可知所谈应是鞋子。男孩还谈到了要买短裤，对应短文内容可知短裤的价格是16美元。3. Ss read the conversation and the Mr. Cools ad and fill in the blanks. Check the answers.4. Work in a group of three students. Role-play the conversation. 5. Let some pairs come to the front and role-play the conversation. X. Language points1. 基数词表达1) one到twelve，拼写和读音无规律。2) thirteen到nineteen，“十几”，在个位数后加后缀-teen，注意thirteen, fifteen和eighteen。3) twenty到ninety，“几十”，以ty结尾，注意twenty, thirty, forty, fifty, eighty。 4) 2129直到9199，“几十几”, 用整十位数加个位表示, 中间用连字符“-” 把十位和个位连接起来。 5) one hundred “一百”，也可说 a hundred, 可加具体数字，如nine hundred (900)。2. 基数词用法 基数词只能修饰可数名词，要注意数词和名词在数上要保持一致。如： 一名学生；两名男孩；二十个苹果；三十三个鸡蛋 one student; two boys; twenty apples; thirty-three eggs3. Come and buy your clothes at our great sale! buy v. 买 buy sb. sth./ buy sth. for sb. 给某人买某物 e.g. 我们给妈妈买件新毛衣吧。 Lets buy mom a new sweater. = Lets buy a new sweater for mom.clothes指身上穿的各种服装，包括上衣，内衣，裤子等，是衣服的总称。不能直接与数词连用，但可与some, many, these或those等连用。e.g. 看！那边的衣服大减价了。 Look! Some clothes are on sale over there. sale是sell的名词，on sale “出售；廉价出售”，同义短语at a great sale。e.g. 今天这家商店的毛衣大减价了。 The sweaters in the store are on sale today. 4. We sell all our clothes at very good prices. all与定冠词、指示代词、形容词性物、主代词等限定词连用时，all应放于这些词之前。如： 所有这些学生；她所有的衣服；所有那些房间 all the students; all her clothes; all those roomsat very good prices 以
