Step1、Class opening and review

[设计意图]师生对话，拉近师生距离，通过对话复习所学单词，相关句型，为新授知识做好准备。
Step 2、New Concepts
T:I like hamburgers. Do you like hamburgers?

T：Okay !let鈥檚 go to the FKC.(课件展示KFC)She is a waitress. Do you have any hamburgers?
W:Yes, lots of hamburgers.

How much are/is the___?(由价格引出expensive . on sale)
[设计意图]教师示范到KFC里买东西，先用How much for one ___? 来提问价格，然后再用新句型How much is the ____? 来提问价格。使同学们明白这两句话的意思相同,以旧带新，在情景中区别运用How much is the ___? 和How much are the ___?在对话中明白expensive, on sale的意思。此外，我将课本内容做了拓展，加入了dollars,让学生感触西方文化。
Step3、Practice
(1)Talk about the price.
(2)Show a short movie answer the question: How much are the bananas?
(3)Go shopping in groups
[设计意图]在情景中操练句型，集看、听、说多种感官为一体，充分调动学生的能动性。教育学生少吃垃圾食品，注意健康饮食的良好生活习惯。
