教学过程

Step 1.Warm-up and lead in.（略）

Step 2.New content.

T:Let’s buy some potatoes.带读句子。

T:Many foods are made from potatoes.

For example:French fries/potato chips.

设计意图：在教师和“售货员”表演的购物对话中呈现新单词，让学生感觉到英语学习与其生活密切相关，激发其求知欲。通过一个小魔术，将单词 tomato变成了potato,激发了学生的学习兴趣，学生更愿意参与到学习中来，也利于他们后期单词的背诵和记忆。

2.Let’s play.

教师在屏幕上出示图片，学生造句。

S2：This is a potato.These are potatoes.

S3：I like potato chips.

S4：...

3.Let’s chant.

PPT播放音乐节奏,师生拍手吟唱。

tomato,tomatoes,Let’s buy some tomatoes.

potato,potatoes,Let’sbuy some potatoes.

candy, candy, Let’s buy some candy.

设计意图：游戏和Chant不仅调动了学生的学习积极性，也活跃了课堂气氛，使学生在愉快的氛围中学习单词和句型，将学生带入英语学习的乐园。

Step 3.Practice.

T:Jenny,DannyandMrs.Smith are atthe supermarket,too.

1.Let’s listen.

S5:No.

T:Why?

S6:Candy isn’tgood for their teeth!

2.Let’s read.

（1）Read the text after the tape.

（2）Read the text in groups and try to retell.

Step 4.Consolidation and Extension.

（1）Make a shopping list.

T:There are many kinds of goods in the supermarket.What do I buy?I’d like to make a shopping list.

（2）Make dialogues according to the shopping list.

A：What do you want to buy?

B：I want to buy...How about you?

A：I want to buy...How about some...?

...

（3）Show to the class.

设计意图：通过让学生自编对话巩固和拓展所学内容，利用新句型 How about...?给出购买建议，引导学生动脑筋，发散思维，训练学生灵活运用所学语言的能力。

（4）Moral education.

T:Look! This is my cloth shopping bag.This is a plastic bag.

Which bag do you like?Why?
