Please pay attention to the long sentences:
(1)A girl comes up to Brian’s table.
(2)Do you have any other things for sale?
(3)What is it for?
(4)You can do your homework while you ride your bike.
(5)That’s a very low price for such a great product.

StepⅢ.Listening
T:Listen to the tape with your book closed and fill in the blanks.
1.You can use one dollar to buy 　　　　cookies.?
2.Danny’s invention costs 　　　　dollars.?
【Keys】　1.four　2.five
[设计意图]　加深同学们对细节的掌握,学生们在有了一定的信息输入之后,才能在这一部分写出所缺信息。
StepⅣ.Post-listening Activities
After listening to the tape,get the class to read them aloud.
Ss read aloud.Focus on the stressed words,pronunciation and intonation.
[设计意图]　学生在听了细节之后,朗读巩固,训练学生的语音语调,培养学生运用目标语言进行交际的能力。

(1)How many cookies does the girl buy?
(2)Does Brian sell anything else?
(3)What’s Danny’s invention?
2.Then ask some volunteers to read the passage.

【Keys】　1.(1)Four cookies. 　(2)No, he doesn’t.　(3)It’s a Danny Desk-Cycle.　3.(1)F　(2)T　(3)F　(4)T　(5)F
☆教材解读☆
1.A girl comes up to Brian’s table.?
come up to意思是“走到跟前;走近”。come up to中的to可以省略,单独使用come up 时,表示“走近,靠近”,尤其指靠近人,与人说话。
My teacher came up to her and asked her to do the homework.我的老师走向她,要求她去做作业。
【拓展】　come up to还可以表示“从……上到”,通常指从南到北,从小地方到大地方。
She came up to Beijing on vacation.
她上北京度假了。
2.Do you have any other things for sale??
句中for sale意思是“待售”。
This car is for sale.这辆车要出售。
【辨析】　for sale,on sale
(1)for sale意思是“待售”,指的是正要出售,还没有销售出去。
(2)on sale 意思是“出售”,指的是廉价出售,减价处理,含有打折之意。
Those bags are for sale,and they are on sale for 5 yuan.那些包准备出售,而且减价处理只要5元。
3.What is it for??
“What…for?” 是在不理解对方的动机或者询问对方的目的的常用语,相当于“Why?”。但是“What…for?”侧重于询问目的,回答时常用不定式或者目的短语;而“Why?”侧重于询问原因,一般用because引导的句子作答。
—What does he want a knife for?
他要小刀做什么?
—To cut the orange.切橙子。
—Why does she like swimming?
为什么她喜欢游泳?
—Because it can make her keep healthy.
因为游泳能使她保持健康。
4.You can do your homework while you ride your bike.?
句中 while 是引导词,在句中引导时间状语从句,意思是“当……时候;在……期间”,表示两个延续性动作同时进行。
While my mother is cooking,my father is reading a book.当我妈妈正在做饭的时候,爸爸正在看书。
　　【辨析】　while,when,as
(1)while 引导的时间状语一般是指一段时间,它引导的从句中的谓语动词必须是延续性动词。强调从句中的动作和主句中的动作同时发生,或者指主句中的动作发生在从句动作发生的过程中。
Someone knocked at the door,while I was washing clothes.当我正洗衣服的时候,有人敲门。
(2)when 引导的时间状语从句既可以指一段时间,也可以指某个时间点,从句的谓语动词既可以是延续性的,也可以是非延续性的,主句和从句中的动作可以是同时进行,也可以有先后。
She was doing her homework when it rained.下雨的时候,她正在写作业。
(3)as可以指的是不分先后、并列发生的情况,尤其指的是瞬间动作或者事件同时发生,也可以指同时发生变化的两种情况,从句中的谓语动词既可以是延续性动词,又可以是非延续性动词。
Lucy did the chores as she listened to the music.露西边听音乐边干家务活。
5.That’s a very low price for such a great product!?
句中price意思是“价格”,at a very low price意思是“以很低的价格”。表示价格的高低要用high 或者low,不能用cheap或者expensive,cheap或者expensive是表示物品自身的贵贱。
She bought a skirt at a very low price.
她以很低的价格买了一条裙子。
That skirt is very cheap.那条裙子很便宜。
【拓展】　at a price of表示“以……价格”。
She bought a new watch at a price of 1 000 yuan.她以一千元的价格买了一块新手表。
【注意】　询问价格用“What’s the price of…?”,相当于“How much is/are…?”。
[设计意图]　学生通过阅读课文,懂得重点内容,并且通过回答问题来巩固对课文的理解和掌握;朗读课文并完成练习题1,懂得课文重点内容。
StepⅥ.Complete Let’s Do It!
Ask the students to read the lesson and finish No.1,No.2 and No.3.Read for several times until the students can understand the lesson themselves.Ask the students to finish them in groups.
[设计意图]　Let’s Do It! 中的No.1、No.2和No.3 都是针对课文内容的。认真阅读课文,训练阅读能力。同时分组教学培养合作精神,训练阅读能力。
StepⅦ.Task
Ask students to come to the front of the classroom,and some start walking towards others as the teacher says “go”.They must stop as the teacher says “stop”.Then they can make a new dialogue to finish No.4.
[设计意图]　No.4的重点是训练本课内容的拓展延伸,训练关于购物和销售的用语,注意课文内容,考查学生的分析总结能力,尤其是口语表达,掌握运用英语。
