三、教学步骤
Step One Lead in （6 min）
1. Tell us your shopping experience. （3 min）
Teacher asks, “Do you sometimes go to the supermarket with your mother? What do you 2 usually buy in the supermarket?”
Students may discuss the questions with partners, then three or more students tell others their
shopping experience.
Teacher says, ‘Happy Mall often provides goods on sale. Let’s have a look at the poster and
catch the right time to buy the goods at the lowest price.
（设计意图: 该步骤联系学生的生活经历，易于激发他们对阅读活动的兴趣。教师联系本地大型超市，引出Activity 12中的海报，并把海报中的超市名称改为本地的超市，为后面的阅读活动设置了真实的情境。）
Step Two Reading (Activity 12, 13, 19) (9 min)
1. Activity 19. Read and group. （3 min）
Teacher says, “There are many goods on sale in Happy Mall. Can we put the same kind of
goods in the following baskets? Please think about it with your partner, and find the right goods
for each basket.”
Then students check answers together.
(设计意图:该步骤能使学生熟悉海报上的所有商品，为后面寻找海报细节信息的活动做出铺垫。同时商品归类的活动有助于培养学生对词汇意义分类并记忆的词汇学习策略。)
2. Activity 12. Have you got a quick mind? (3 min)
Teacher asks, “Read the poster carefully and try to find out answers to the following
questions.”

3. Activity 13. Read and judge. (1 min)
