3B Unit 2 Yes or No 教案（第一課時）

t: what’s this?
ss: it’s a computer. (黑板上出示句子，學生朗讀)
ss: is that a tv?   no, it’s isn’t. it’s a computer.
4) t: (拿出一袋子) nancy brought us a bag. what’s in it? guess.
學生觀察形狀猜。
t: is this a rubber?   ss: no, it isn’t.   t: yes, it’s bigger.
t: is this a computer?    ss: no, it isn’t.   t: yes, it’s smaller than a computer.
t: you can guess. is this a …? (教師用動作提醒學生猜一些形狀相似的物品)
ss: is this a walkman/ pencil box/ book/ camera/ telephone…?
t: nice try! but it isn’t a …. (猜錯也給予一些小獎勵)
t（隔著袋子打開收音機）listen, what’s this?
ss: it’s a … 教師公布答案，教 radio, 指導發音，邊讓學生回答，邊讓他聽。
t: (to nancy) can i have a look?
n: sure. 拿出給學生看。 what a nice radio!
5) guessing game. what’s in my left hand?
教師將照相機和收音機分別拿在兩個手里，讓學生猜左手是什么？
s: is that a camera?    t: no, it isn’t. it’s a radio.  猜對的得獎。
(利用一些真實的物品，進行一些帶有游戲性質的操練，讓學生看到、摸到、聽到他們的學習對象，這些物品的英文他們很自然就記住了。而且，單詞始終放在句中練，句型也得到了鞏固。)
step 3 text teaching
1. t: listen, the telephone is ringing. (answer the telephone). oh, that’s gao shan. he asks us to visit him now. let’s go to his home. ok?
屏幕出現gao shan家的大門。
t(knock the door) what should we say?
ss: may i come in? (每個大組輪流說)
2. t: now nancy is visiting gao shan. listen to their conversation and think about these two questions.
a. is that a dog on the table/in the living room? 
b. is that a radio on the desk/ in the bedroom?
(show the picture and listen to the tape)
教師加一些敘述性的話
t: now, nancy is at the door. what’s she saying?... now, they are in the living room. nancy sees something between the sofas. what’s that?.... now, they are in gao shan’s bedroom. nancy sees something near the vase. what’s that?
(listen to the dialogue again.)
ss give the answers.
ans: no, it isn’t. it’s a telephone.
    no, it isn’t. it’s a camera.
(第四幅圖片本節課沒有重點講，教師稍做解釋，非本節課重點。)
3. t: let’s read after the tape. …read after me. … boys, you’re gao shan. girls, you’re nancy. ….exchange, that’s fun….practice pic 1 to 3 in pairs.
4. ask two or three pairs to act the dialogue in front.
(把課文放在情境中教，學生仿佛親身經歷了一番，印象深刻，表演時就更自然。)
