Step 1. Lead in

T： Where do you live？

S： I live in….

T： How do you go to school？

S：By bus.（By bike. By car… ）

【設計意圖】在這一環節中，復習有關交通工具的詞匯，為下一步的學習做好充分的準備。

Step 2. Presentation

1.教學單詞airplane（plane），train， fast， slow。

T： （屏幕出示一幅圖片）Look， this is my friend Cathy. She wants to go on a trip to Canada. How can she go there？ By bus？

S： No.

T： Canada is far from China. A bus is slow. （板書并領讀）She can go there by airplane. （拿出飛機單詞卡片貼在黑板上，教學airplane（plane）， 向學生介紹飛機的兩種寫法）

An airplane is fast. （板書并領讀）

T： I want to go to Beijing on this Children’s Day. Can I go there by bus？

S： No.

T： How can I go there？

S： By car.

T： But I don’t have a car.

S： By airplane.

T： Oh. The airplane is fast， but I don’t have enough money. I think I can go there by train. The train is faster than the bus， and cheaper than the airplane. The train is just right for me.

2.教學句型__________ is faster than._______is slower than_________.

T： Which one is fast？ Which one is slow？ （CAI課件出示飛機和火車圖片）

Step 3. Practice

1.出示飛機、火車、公共汽車等有關交通工具的每對圖片，讓學生說出圖片要表達的內容。

Eg： A train is _________ than a bus but__________ than an airplane.

2.多媒體展示自行車和大卡車，出租車和飛機，小雞和兔子，劉翔和Miss Cui等等圖片，學生對比，運用句型_________is faster（slower） than___________.

Eg： A bicycle is slower than a truck. A truck is faster than a bicycle.

A cab is slower than an airplane. An airplane is faster than a cab.

The chicken is slower than the rabbit. The rabbit is faster than the chicken.

Liu Xiang is faster than Miss Cui. Miss Cui is slower than Liu Xiang.

【設計意圖】借助多媒體和圖片出示不同的交通工具，有趣的動物形象，卡通人物，鼓勵學生模仿說句子，激發學生敢于表達所學句型。

3.Student book：

T： We know Li Ming wants to go on a trip to Beijing. How do Li Ming and his mother go to Beijing？ Let’s listen to the audiotape and try to find the answers.

Step 4. Consolidation

Demonstrate a dialogue with a volunteer.

T： Boys and girls， Children’s Day is coming. Where do you want to go ？ How do you go there？ Talk about it with your friends. Here are some places and vehicles for you.

（黑板上為學生提供地點和各種交通工具的詞，幻燈片為學生呈現創編對話時所需要的句型）

Children’s Day is coming. I want to go on a trip. Let’s go to ________by_________. I want to take a__________.__________is faster than________._________is slower than_________.

【設計意圖】通過創設真實的語言情境來檢驗學生能否準確地運用本課所學句型。

Step 5. Class Closing

Homework：讓學生去調查身邊的人或事物，寫一寫________is faster /slower than_________.

教學反思：

本節課是一節典型的關于比較級的語法課。小學階段的語法教學應體現隱性語法教學原則，作為教師不應為學生直接講解語言中出現的語法概念，而是應通過創設的語言情境，讓學生在活動中去感悟、理解出現的語法現象，從而掌握所學的語法知識。本節課，通過創設真實的語言情景，為學生呈現公共汽車、飛機和火車的圖片，教學比較級句型__________is faster than_________.___________is slower than_______. 所以教師又充分利用了兒童節即將到來這一真實情景，為學生提供了學習英語和用英語交流的語言環境。通過本課的學習，學生可以較好地掌握所學單詞和句型，并能積極主動地加以運用，達到了預期的教學目標。
