Teaching procedures 教学过程
Step 1 Free talk
T: Let’s talk about the changes. Here is the change. We can talk about it like this.
【设计意图：借助free talk活跃课前气氛，复习关于job的名词，引起学生兴趣，又以job为线索引入Sound time板块的学习。】
Step2 Sound time
1. Look and guess
T: In my family, not only me, look at this picture. She is my mother. What’s her job?
S: A teacher.
T: You’re right. How about this picture? He is my cousin. What’s his job?
S: A worker.
T: Well done!
（教师出示图片，学生根据图片信息猜测相关职业，以悬念的方式引入Sound time版块）
T: Let’s listen to the sound time and imitate. Pay attention to the intonation and pronunciation.
(学生听完录音后进行模仿；教师邀请学生朗读，看谁读得最好。)
2. Sound time
(学生注意单词中的字母组合er，发现其读音为/ɜ/；教师鼓励学生想出更多含有字母组合er并且发音为/ɜ/的单词)
er /ɜ/ driver, brother, father, farmer, waiter, water, paper
T: Can you make a sentence with any two of these words?
S: …
T: There are some other words. They have the same sound of “er”. Can you read these words?
S: …
T: How much do you know about “er”?
S: …
【设计意图：由job为线索，通过猜谜引出Sound time的内容，通过听读模仿和找规律，让学生自主找出er在这里的读音。并通过相关练习学以致用。】
Step3 Cartoon time
1. Look and say
T: My mother is a teacher. How about Miss Fox?
S: She is also a teacher.
T: What are they doing now?

(师生一起带着问题观看视频，对Cartoon time形成初步认知。在核对问题答案的过程中，教授新词汇。)
3. Read and answer
T: Yes, Miss Fox feels unhappy, because Bobby is looking out of the window. But later, Miss Fox gets angry, why? Let’s read the Cartoon time together, and try to find the answer.

4. Think and imagine
T: Miss Fox gets angry, because Bobby and Sam are talking. So, if you were Miss Fox, what would you do?

(教师进行示范，随后要求学生四人一组表演课文内容，并邀请两组或更多学生在全班同学前表演)
【设计意图：由teacher为线索，引出Cartoon time的内容，通过小组间的讨论、判断等方式让学生理解课文内容，并通过表演让学生感悟到学习内容的趣味性。】
