Teaching procedures 教學過程
Step 1 Free talk
T: Let’s talk about the changes. Here is the change. We can talk about it like this.
【設計意圖：借助free talk活躍課前氣氛，復習關于job的名詞，引起學生興趣，又以job為線索引入Sound time板塊的學習。】
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!
（教師出示圖片，學生根據圖片信息猜測相關職業，以懸念的方式引入Sound time版塊）
T: Let’s listen to the sound time and imitate. Pay attention to the intonation and pronunciation.
(學生聽完錄音后進行模仿；教師邀請學生朗讀，看誰讀得最好。)
2. Sound time
(學生注意單詞中的字母組合er，發現其讀音為/ɜ/；教師鼓勵學生想出更多含有字母組合er并且發音為/ɜ/的單詞)
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: …
【設計意圖：由job為線索，通過猜謎引出Sound time的內容，通過聽讀模仿和找規律，讓學生自主找出er在這里的讀音。并通過相關練習學以致用。】
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?
S: They are having an English class.
2. Watch and answer
T: Watch the cartoon, and try to answer this question: At the beginning, Miss Fox feels unhappy. Why?
S: …
(師生一起帶著問題觀看視頻，對Cartoon time形成初步認知。在核對問題答案的過程中，教授新詞匯。)
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.
S: …
(教師設置懸念，進一度激發學生的興趣，邀請學生一起閱讀Cartoon time，進一步加深對Cartoon time的認知。)
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?
S: …
(教師設置開放性問題，貼近真實的課堂環境，給學生更多的思考空間，鍛煉學生的發散性思維。)
5. Listen and repeat
T: Let’s listen to the Cartoon time together. Pay attention to the intonation and pronunciation carefully.
6. Let’s show
T: Now, we are familiar with the Cartoon time. Can you act it out?
S: Yes, we can.
T: Please prepare it in groups of four in one minute. Then, act it out in front of the class.
S: …
(教師進行示范，隨后要求學生四人一組表演課文內容，并邀請兩組或更多學生在全班同學前表演)
【設計意圖：由teacher為線索，引出Cartoon time的內容，通過小組間的討論、判斷等方式讓學生理解課文內容，并通過表演讓學生感悟到學習內容的趣味性。】
Step 4 Expansion
1. Discussion
T: Who do you like best in this story? Why?
S: …
2. Guess
