4.Let’s think.

Why can’t Sarah buy this skirt?

（1）在文中找出答案并画线：Because it’s too expensive/cheap.

（2）T: The skirt is $89.Do you know the Exchange rate of RMB and US dollar? 你们知道人民币和美元的汇率吗？Let’s go to Baidu and find out.（通过百度网页查询人民币汇率）

1 美元≈6.6995 人民币 89美元=596.2288 人民币

（5）T: So will you buy this umbrella? ...Why? ...Yes.It’s too expensive.（板书）

设计意图：创设批判性问题情境“Will you buy...?”，学生运用生活经验来分析判定该不该买，该买什么。在理解了expensive 和cheap 的基础上，学生通过分析判断，思维的深刻性、灵活性、批判性和创造性都得到锻炼和提升。

Ss: It doesn’t matter./You can choose another one./...I’m sorry.

Emotion: We should buy suitable things at a reasonable price.We buy things not because they’re cheap or they’re expensive，but because we need them and their price is reasonable.

设计意图：结合文本图片的情境和所学内容，引导学生体会文本主人公的思维。同时，学生通过思考，学会关心他人，并能提供适当的建议来开导、帮助他人，引导学生学会友善地“Care for others”。

6.Listen and imitate.

7.Practise the dialouge.

T: Now you know the text very well.Can you finish the dialogue in this way?

Step 5.Consolidation

1.Watch a new video,find out the answers and think.

T: Boys and girls,Sarah and her mum go to another shop.Let’s watch the video and find out if Sarah will buy something.How much is it?

T&S: What will Sarah buy?A dress.How much is it? It’s eighty-five yuan.Is it expensive?No...It’s cheap.Yes,it’s cheap.Is it pretty?...Yes.So Sarah takes the suitable dress at a reasonable price.Right? What do you think of Sarah?...She is happy / great!

设计意图：利用文本信息创造性地创设从不能买到能买的情境，引导学生再次学习和建构目标语言，为任务的完成打下基础，提升思维的深刻性、创造性和敏捷性。

2.Fulfill the task: Set up street stalls and buy something.

OK,boys and girls.Now let’s set out things on the street.We have our own street stalls.I need some vendors to sell things.And the others are customers.You can buy things with your coupons.Who wants to be the vendors? As rewards,you can get another coupon of 10 yuan...Thank you.

T: Boys and girls,today we’ve learned how to ask and describe something,and how to ask and answer the price.I’d like you to buy things you need with reasonable price.You can go to street stall and find what you need.OK?

设计意图：学生在交际情境中发现、感知、理解、体验语言，并吸收、内化和建构成自己的语言机制，充分发挥想象力，从而能够独立地、创造性地解决实际问题。设置情境去解决问题，完成任务也是发展创造性思维的重要途径。
