T: I’m sorry. I can’t. I’m very busy.

Tom: What are you doing now?

T: I’m having my English lesson.

Tom: That’s great. Goodbye.

T: Bye-bye.

学生们扮演Tom与教师练习如上对话。

师生进行如下问答：

T: What are you doing?

S1: I’m having my English lesson.

T: Please practise in pairs.

学生两两操练。

[设计意图]

通过创设与Tom打电话这一情景，教学句型“What are you doing?”。在此过程中。学生不是简单机械的学习，而是在真实的语境中操练，巩固新句型。同时巧妙地利用师生正在上英语课展开问答，学生很自然的明白了“What are you doing?”的意思。

2. 教学词组 cleaning the room，writing an email，washing the clothes。

课件出示Harry打电话场景。

T: Look at the picture boys and girls, what is he doing?

Ss: He is calling someone. (课件出示句子 He is calling someone.)

T: Listen, what is he saying? (播放课件视频，学生模仿，出示单词busy的解释)

 [设计意图]

通过课件为学生展示原汁原味的英语打电话场景，并从句型“What are you doing?”向“What is he doing?”过渡。为接下来操练词组以及最后的创编新对话做好准备。

T: (课件出示句子 “Lily is busy. ”以及Lily打扫屋子图片) This is lily. Lily is busy. What is she doing? (课件出示句子“She’s cleaning the room.”)

Ss: She is cleaning the room.

师生展开如下对话：

T: Lily is busy. What is she doing?

S1: She’s cleaning the room.

T: Now you ask one of your classmates. (引导学生提问其他同学。)(教师板书“cleaning the room”。)

课件出示爸爸在电脑上写邮件图片。

T: Look at the picture. (课件出示“Dad is… What is he…?”)

Ss: Dad is busy. What is he doing?

T: He’s writing an email. （课件出示句子，教师领读，板书“writing an email”。）

学生两两操练以上对话。

课件出示妈妈洗衣服图片。

T: Mum is washing the clothes. (教师领读，板书“washing the clothes”。)

学生两两操练。

[设计意图] 

  借助课件图片学习词组简单明了，把所学词组放在句子中，逐步撤除语言脚手架，引导学生以填空的形式操练，实现语言的内化，尽量弱化教师的作用。学生通过与同伴合作完成词组的学习。

3．学习课文文本内容

T: Lily is calling. Whom is she calling? Let’s listen. (播放无字课文视频。学生回答问题。)

S1: She is calling her grandpa.

再次播放课文无字视频，学生回答问题。

T: What are they talking about? Listen again and answer my questions.

  a. What is Lily’s dad doing?

  b. What is Lily’s mum doing?

S1: Dad is writing an email on the computer.

S2: Mum is washing the clothes.

[设计意图]

 两次听录音回答问题的任务，引导学生听录音获取课文信息，问题难度逐渐增加，帮助学生深入理解对话。

T: Now, please listen and repeat. (课件出示带文字课文视频，引导学生逐句跟读并纠正学生的发音。)

  【练习】Step 3. Practice 操练巩固

1. 教师领读课文，学生跟读。

T: Boys and girls, please follow me to read the dialogue.

Ss: OK.

2. 学生小组操练课文，教师进组指导。

【练习】Step 4. Production 拓展延伸

根据图片创编新对话。课件出示六幅图片，学生两人一组，任选一幅，根据提示创编新对话。教师进组指导。学生前台进行表演。
