多形式開展質疑教學，讓英語課堂活起來

一、教師質疑

教學“Project English”九年級上冊Unit 1 Topic 2 la Read and Understand時，我設計了下面一組問題。

T： What was the worlds population in 2005？

Ss： It was about 6.5 billion.

T： Whats the population of China now？

S1： Its about 1.3 billion.

T：What problems do you think Chinas large population has caused？

S2：There is less living space for each family. And its difficult for lots of people to find jobs. We are short of energy and water. Most cities are more crowded than before， and the traffic is much heavier.

T：What has the government done to control the population？

S3：The government has carried out the one-child policy. And it has worked well.

T：Are you the only one child in your family？

S4：Yes， I am.

二、教師與學生互相質疑

教學直接引語與間接引語時，我向學生質疑：句子“The teacher told us that the sports meeting would be put off.”中，賓語從句的時態為什么用過去將來時？學生回答：如果主句是一般過去時，賓語從句部分需用過去時態。緊接著我拋出句子：The teacher told us the earth moves around the sun.這時，學生質疑：賓語從句部分為何不用過去時態，而是用一般現在時態？我解釋：當轉述客觀真理或是引述的狀態和情況到現在仍然是事實時，經常用一般現在時態。我又問：還能舉出例句嗎？有學生說：She said that light travels much faster than sound.

三、學生之間互相質疑

教學定語從句時，我讓學生小組合作，討論下面句子空格處應填入什么關系代詞或關系副詞。

1. I work for a company

sells cars.

2. Many people love the man

songs have great lyrics.

3. There is somebody wants to see you.

4. This is the place he would like to visit.

5. This is the place Deng Xiaoping once lived.

6. Ive never heard of the persons and things you talked about just now.

7. Everything happened at that moment seemed unreal.

8. He is the very man can help you.

通過巡查，我發現了學生的質疑之處，并幫助他們達成共識：“This is the place which/ that he would like to visit.”引導詞which或that在從句中作賓語，而where不能作賓語。“This is the place where Deng Xiaoping once lived.”where在從句中作地點狀語。“He is the very man that can help you.”引導詞用that，不能用who，因為當形容詞前有the only，the very，the last等詞修飾時，引導詞只能用that.

四、學生自我質疑

例如，預習“Project English”九年級Unit 1 Topic 3 Section B時，通過自學，學生可以發現新的知識點。其中難點集中在：decide on sth.與decide to do sth.有什么區別？so...that... 與...so that...有什么區別？短暫性動詞需要與since， for表示一段時間的時間狀語連用時，要如何轉化？帶著這些疑問，學生獨立思考，通過與已學的知識做比較或者查閱有關參考書，盡力解決疑難。這樣一來，既能培養學生發現問題的能力，又能培養學生解決問題的能力，在學習中就能切中要害，提高效果。
