四、教学过程
Ⅰ.Revision

Ⅱ.Presentation.
1、出示两支不同价钱的钢笔， ask and answer:
T: How much is this pen? S: It’s five yuan. T: How much is that pen? S: It’s fifty yuan.
教师引出新知识点，连续说三次，提醒学生注意新单词： This pen is five yuan.
That’s cheap! That pen is fifty yuan. That’s expensive! 让个别优生模防着说，
注意纠正expensive的发音。 学习单词cheap和expensive，开火车的形式检查That’s cheap!和That’s expensive!
2、巩固操练，用课件出示各种不同价钱的物品，师生之间、小组之间、男女生之间、同桌之间进行多种形式的问答操练。

3、拿出刚才出示过的一支钢笔，学生之间问答A: How much is this pen?
B: It’s five yuan. 教师再拿出相同的另外一支，尽量让多位优生说问句，启发学生寻找错误，
得到正确的句子How much are these pens? 充分让学生思考答句，最后教师说出三个句子让学生选择It’s 10 yuan. These are 10 yuan. They are 10 yuan.
