I’ll finish this lesson in five steps.
五、Teaching steps
Step1 Preparation
Now I have 4 gardens,they are for group 1,2,3,4.If you do well,you can get some flowers for your groups.(教師在黑板上畫個四個花園的形狀，分給四個小組，如果在課上他們表現(xiàn)的好就可以為他們組獲得花朵。既激發(fā)了同學(xué)們的竟?fàn)幰庾R，同時也為板書增色彩。)
1.Do as I do:walking, walking ,I’m walking./Running, running, I’m running./ Flying,flying,I’m flying./ Jumping ,jumping,I’m jumping./Swimming,swimming,I’m swimming./Climbing,climbing,I’m climbing./Cooking,cooking,I’m cooking dinner./Cleaning,cleaning,I’m cleaning the room…(通過課件出示這些動詞，讓學(xué)生跟我做，這個熱身活動既復(fù)習(xí)了現(xiàn)在進(jìn)行時，為新課做鋪墊，也為后面的擴(kuò)展活動做準(zhǔn)備。)
2.Play a game(啞劇猜謎)
每組派兩名同學(xué)上臺做一個剛才熱身時的動作，然后老師問：What is …doing?He’s /She’s ….(由I’m doing …過渡到She’s /He’s doing…層層遞進(jìn).)
3. We are ready to go for the field trip now.Let’s sing a new song of “Field Trips”.
老師領(lǐng)唱歌曲。(以教學(xué)主題歌曲創(chuàng)設(shè)活動情境，提示活動主題，貼切自然。)(
Step2 Presentation
1.Last weekend our class had a field trip,too.We took many pictures about the field trip.Now let’s look at the pictures.
a.taking pictures
Look at this picture.What is …doing?引導(dǎo)學(xué)生回答：He’s doing an experiment.
教師出示“doing an experiment”的卡片，讓生跟讀，鼓勵學(xué)生邊說邊做動作。接著板書單詞，讓學(xué)生一起書空,并配上相應(yīng)的簡筆畫。然后讓學(xué)生小組讀，個人讀。再拿出準(zhǔn)備好的試管，讓幾個學(xué)生做動作，師先問：What’s… doing?讓生回答：He’s doing an experiment.再讓生問生回答。(練習(xí)形式由單詞到句子，做到詞不離句，層層遞進(jìn)。)
b.Look at this picture.What’s he doing?師示范說：He’s watching insects.師在黑板上畫兩只螞蟻,并介紹“insects”.以同樣的方式練習(xí)“insects”,并讓一生拿著課前準(zhǔn)備的放大鏡上黑板做觀察螞蟻的動做,來練習(xí)What’s he doing? He’s watching insects.
因?yàn)?ldquo;experiment和insects”的發(fā)音是個難點(diǎn)，所以在這個地方設(shè)置了一個冷暖游戲來突破這兩個難點(diǎn)。(讓一生背對全體學(xué)生，把詞卡藏在另一生的書底下，讓這生找，全體學(xué)生一起喊“experiment”，或“insects”當(dāng)這個學(xué)生離詞卡越近時，學(xué)生聲音越大，離它遠(yuǎn)時，聲音漸小，讓生跟據(jù)聲音的大小來找尋詞卡。)
c. 以上述同樣的方法操練catching butterflies,picking up leaves,taking pictures.
2.Listen to the tape.
聽音正音部分我放了兩遍錄音，第一遍只讓學(xué)生邊聽邊指，指讀對學(xué)生來說是很有必要的，可有效改善學(xué)生的單詞認(rèn)讀能力差的情況。第二遍跟讀。
3.Read in groups.
單詞導(dǎo)呈和聽音正音結(jié)束后的合作交流，我認(rèn)為就是學(xué)生咀嚼、消化的過程，是學(xué)生查漏補(bǔ)缺的過程，是為后面的Practice環(huán)節(jié)作好知識上的鋪墊的過程。學(xué)生在活動前，教師一定要注意提出具體的學(xué)習(xí)要求，避免學(xué)生無目的的讀。我的合作要求是：Now read in groups. Pay attention to your pronunciation.You can help each other. Let’s see who reads best.
Step3 Practice
1.教師先用詞卡檢查學(xué)生的認(rèn)讀情況。
2.What’s missing? (說和認(rèn)讀的訓(xùn)練)
3.Guessing game:what’s he doing?
讓學(xué)生到講臺上看老師出示的單詞做動作，讓其他學(xué)生猜。師先問：What’s he/she doing?生答：He’s/She’s…然后生問生答。
4.Let’s chant:
Doing, doing,what’s he doing?
Watching,watching,he’s watching insects.
Taking,taking,he’s taking pictures.
Picking,picking,he’s picking up leaves.
Catching,catching,he’s catching butterflies.
Doing,doing,he’s doing an experiment.
(Chant既朗朗上口激發(fā)學(xué)生興趣，又富有實(shí)際意義，有利于學(xué)生理解與記憶。)
Step4 Production
1.課前準(zhǔn)備好四張大紙，每組一張，每張紙上都有個中心活動如： Group1 is doing housework. Group2 is having a field trip. Group3 is having a sports meeting. Group4 is staying in the classroom. 每張紙上的動詞都圍繞這個中心活動，配上如李麗在照相的圖與相應(yīng)的動詞，但是只給出動詞，讓學(xué)生完成填空，并在小組內(nèi)練習(xí)句型。比如 take___ pictures讓學(xué)生試著加上ing,并讀出。
2.小組內(nèi)練習(xí)，利用句型What is Li li/he/she/ doing? He’s/She’s _____ing.充分討論。
3.讓各組學(xué)生匯報結(jié)果。
適當(dāng)?shù)募由锨楦惺芙逃篖ove nature,love life.
(通過便設(shè)情境，訓(xùn)練學(xué)生的口語交際能力及實(shí)際運(yùn)用語言的能力。)
Step5 Production
1. Do Activity Book.
2. 總結(jié)評價哪個花園里的花最多，即哪個組是今天的獲勝者。
3. Homework: ⑴.Listen to the tape and remember the 5 verb phrases. ⑵ Write a passage about your field trip.(將英語學(xué)習(xí)延伸到課外，達(dá)到學(xué)以致用的目的。)
