Step 3 Cartoon time
1. Watch and choose
(呈现Bobby和Sam在商店的图片）
T: Who are they? Ss: Bobby and Sam.
T: Where are they? S1: In the shop.
T: How do you know?
S2: 通过Can I help you?这句话可以知道，因为店员一般开始都会说这句话。
T: You are so clever. But what would Bobby like? How many would Bobby like? Now, let’s watch the cartoon and choose.
What would Bobby like?
(rings图片、necklaces图片、bowknots图片、books图片）
How many would Bobby like?
(设计意图：呈现Bobby和Sam在商店的图片，教师引导学生一步一步思考，最后自己找出他们是在商店购物的线索。然后总体感知课文，回答两个宏观的问题。从义卖到商店购物，从杨玲、刘涛、迈克购物到Bobby和Sam购物，上下紧密联系。）
2. Read and find
T: Bobby is a boy, why does Bobby buy these bowknots? Please read the story silently and find the answer, please underline the sentence.
(学生先和同座位讨论交流答案，然后教师提问）
T: Who can tell me who are these bowknots for?
S1: They are for my sister Tina.
(老师带读They are for my sister Tina. 并翻译，此处要向学生说明for是“为了”的意思)
T: Why does Tina need ten bowknots?
S2: Her tail is long.
(教师结合图片教授her, tail和long, 多次带读Her tail is long.并翻译)
(设计意图：再次详读课文，让学生查找细节内容，帮助学生更好地理解故事大意，发现cartoon time的乐趣之处，激发学生的阅读兴趣。）
Let’ read
Read the story loudly after tape.
(播放录音，学生跟读，并提醒他们注意模仿语调和语气，特别是Sam奇怪的语气和Tina 高兴的语气)
Read after teacher.
Read by roles.
(学生四人一小组分角色朗读课文，然后全班一起分角色朗读，比比哪一小组读的最棒。）
Let’s act
(设计意图：有感情的朗读课文并表演有助于进一步巩固课堂所学，让学生在和谐愉快的氛围中学习英语。)
