學(xué)習(xí)目標(biāo)：
語言知識(shí)目標(biāo)：學(xué)習(xí)動(dòng)詞的-ing形式做狀語的語法知識(shí)，完成改寫句子、短文填空等練習(xí)
語言技能目標(biāo)：能進(jìn)一步強(qiáng)化語法的理解與運(yùn)用能力
能熟練掌握動(dòng)詞的-ing 形式在句中做狀語的運(yùn)用
教學(xué)方法：情景教學(xué)法
教學(xué)過程：
一、 導(dǎo)入：運(yùn)用單元相關(guān)的話題或熱點(diǎn)話題導(dǎo)入，注重引起學(xué)生興趣。
讓學(xué)生閱讀主課文The Cat That Vanished，找出含有動(dòng)詞的-ing形式作狀語的句子。
例如：
1. Will, still watching, saw the cat behave curiously.
2. --- he crossed the road, keeping his eyes on the spot where the cat had been investigating.
二、 呈現(xiàn)。將本課時(shí)要復(fù)習(xí)的目標(biāo)語法設(shè)計(jì)到不同形式的情境中。
任務(wù)一、老師出示兩組句子，學(xué)生觀察、思考這些句子，比較第二組句子和第一組有何不同：
1. Will put down his shopping bag and held out his hand.
2. Will watched and saw the cat behave curiously.
3. He kept his eyes on the spot where the cat been investigating and crossed the road.

3. Before ____ his kingdom, he calls his son to him.
4. After ______ about the situation, he decides to kill the witch himself.
5. While ____ by a pool, Ferdinand sees a frog.
三、 歸納。學(xué)生通過觀察豐富的語言材料，發(fā)現(xiàn)、回憶相關(guān)語法現(xiàn)象，并通過同伴合作活動(dòng)，討論語法規(guī)則并總結(jié)歸納語法規(guī)則。
1、出示問題，讓學(xué)生討論并回答后，總結(jié)語法規(guī)律。
�。�1） Which sentences describe two things that happen at the same time?
（2） Which sentence describe one thing happening immediately after another?
�。�3） Look at sentences (a) and (d ). Do the two parts of the sentences refer to the same person?
小組討論：動(dòng)詞的-ing形式充當(dāng)狀語，有什么特點(diǎn)？
動(dòng)詞的-ing形式在句中可以充當(dāng)什么狀語？
2、歸納規(guī)則：學(xué)生將已發(fā)現(xiàn)的規(guī)則及其特點(diǎn)，用自己認(rèn)為最好的方式進(jìn)行歸納總結(jié)。教師匯總各小組的討論情況后展示如下：
動(dòng)詞的-ing形式作狀語時(shí)，表示和謂語動(dòng)詞所指的動(dòng)作同時(shí)或幾乎同時(shí)發(fā)生；動(dòng)詞的-ing形式的邏輯主語和句子的主語一致。（學(xué)生在歸納時(shí)，教師可在旁協(xié)助，并補(bǔ)充完整。）
因?yàn)閯?dòng)詞的-ing形式具有副詞的功能，在句中可作時(shí)間狀語：
Walking in the street, I met a friend of mine.
作方式狀語：He sat at the table, reading a magazine.
作結(jié)果狀語：The boy fell of his bike, breaking his right arm.
作伴隨狀語：Laughing and talking, they went into the room.
作原因狀語：Being ill, I stayed at home.
作條件狀語：Working hard, you will succeed.
作補(bǔ)充說明：The plane leaves at six, arriving in Chicago at ten.
采用歸納教學(xué)法，學(xué)生進(jìn)行同伴合作，一起“觀察----發(fā)現(xiàn)----歸納”語法結(jié)構(gòu)和使用規(guī)則，學(xué)生主動(dòng)參與學(xué)習(xí)，有利于觀察、思維、分析、綜合能力的培養(yǎng)。根據(jù)學(xué)生總結(jié)歸納結(jié)果，教師要進(jìn)行必要的板書。
四、 運(yùn)用：根據(jù)話題一致的原則，設(shè)置不同情境，從句到篇，由易到難，訓(xùn)練學(xué)生在真實(shí)生動(dòng)的語境中達(dá)到活學(xué)活用目標(biāo)語法的目的.
任務(wù)一：讓學(xué)生把下列句子改寫成含有動(dòng)詞-ing 形式的句子
1. When he saw the witch, the boy ran away.
2. Before he starts the war, the king speaks to the prince.
3. While he was fighting in the war, the prince learnt many things.
4. After he had spoken to his son, the king went to war.
5. Because he doesn’t know what to do, Ferdinand follows the frog’s advice.
任務(wù)二：根據(jù)本課所復(fù)習(xí)的'語法，完成下面的短文。

But the witch sat alone, with a wicked smile on her face.
以語篇為單位訓(xùn)練學(xué)生的語法運(yùn)用能力，有助于學(xué)生理解語法學(xué)習(xí)詞不離句、句不離篇的特點(diǎn)，也有助于培養(yǎng)學(xué)生的篇章意識(shí)即有意識(shí)地把單句放在語篇或上下文來理解，有意識(shí)地根據(jù)具體語境選用正確的語法形式。
五、 能力的提升
