背景分析：要想使小組合作學習能順利進行并且充滿活力，采取適當的發展性評價方法與策略至關重要。評價是小組合作學習不可缺少的環節。

(一)教學目標與要求

1、知識目標：能夠聽、說、讀、寫動詞短語的ing形式。

2、能力目標：學生能用句型表述他人正在進行的動作。

3、情感目標：使學生學會與他人進行合作、交流。

(二)教學重點

重點掌握進行時的表達方式和四個短語動詞的ing 形式。

(三)教學難點:重讀閉音節動詞現在分詞形式的變化。

(四)教學設備

cia, tape recorder, pictures

(五)教學步驟及說明

step 1: warm up

1.let’s chant：

what are you doing? what are you doing?

i am sweeping the floor. what are you doing?

i am reading a book. what are you doing?

i am drawing pictures. what are you doing?

i am washing clothes. what are you doing?

i am cleaning the

2. sing a song: what are you doing?

(設計意圖：唱歌是學生喜聞樂見的教學形式之一，通過說唱、唱歌等形式，引入課堂,能夠調動學生的學習興趣。)

step 2: revision

1.show students some photos, ask and answer:

-----what are you doing?

----i’m drawing pictures, reading a book, washing clothes, cleaning the dolls.

2. students write down the phrases on the blackboard and read.

(設計意圖：讓學生進行兩兩合作，一個表演，一個運用句型復習四個已學過的動作，為下面的教學作好鋪墊，使學生能更好的掌握所學的句型。)

step 3. presentation

1. t: what do you usually do at the weekend?

s:i usually……(通過師生對話，直接引出詞組)

t: but i usually read books at home. i like reading books very much.

2. learn to say and spell “read books”.(學生跟讀詞組，并拼寫詞組)

3.show the photos, ask and answer: (從what are you doing句型引出what is he doing?句型)

-----what’s he doing?

-----he’s reading books.

4. learn to say the following three phrases and write down the phrases on the blackboard:(繼續引出其余三個詞組，并將詞組寫在黑板上，為學生以后的活動做準備)

watch tv —— watching tv

sleep —— sleeping

run —— running

step4. drill and practice:

1.look at the photos, ask and answer:

what is he/she doing?

he’s/she’s……

2.look and guess:

there are three actions in the pictures, guess:

what’s he/she doing?

(設計意圖：通過模糊畫面，讓學生猜一猜他們在干什么，鞏固詞組，每幅圖片上三個動作，看誰記得最快，讓小組合作進行說，看哪一組猜得多而準確。學生對猜一猜的興趣較濃，再用小組競爭的形式讓學生進行猜測，這既能調動學生的學習興趣，又能培養他們的團隊的合作精神。)

3.showing the pictures of page 48.practise the sentence patterns.(呈現書中d部分的圖片，操練句型)

4. do an action: students are divided into several groups. one acts teacher and says “everybody. do an action.”
