　　  ：I usually come by bike / bus/ on foot.

　　T：（转向全班） How does he usually come to school？

　　  ：He usually comes to school by bike / bus/ on foot．

　　之后，请这位学生叫起另外一名学生，将这种对话进行下去。

　　Step 2. Read and act.

　　教师在给学生放录音之前，提出问题（Pre－listening question）

　　T: How does David’s father usually go to work？

　　教师放课文录音一遍，指导学生回答问题

　　S: David’s father usually go to work by car.

　　再放录音，学生跟读两遍，熟练听读。

　　T: Now please listen to the tape again. Please pay more attention to its intonation.

　　教师让学生两人一组练习对话。建议在练习中不必拘泥于课本上对话内容，可依据实际情况，有条件的班级可以让若干组学生演示对话。

　　T: Well, please practise your dialogue in the class with your partner.

　　Step 3. Read and make up dialogue.

　　教师让学生两人一组，先将本课第2部分对话阅读一遍，然后使用方框中的替换词，编练新的对话。教师请两组学生表演，并予以讲评。

　　T: Please read the dialogue first, and you will change the word  which is on the table in your own dialogue. Now practise your dialogue with your deskmate , after that I will let some boys and girls act out their dialogues.

　　Step 4. Practice

　　教师指导学生做练习册习题，要求学生用笔头形式完成。

　　T: Let’s do some exercises in text book.

　　Please turn to page…

　　Step 5. Consolidation

　　教师总结这一节课的语言点。

　　1. By air= by plane / by sea= by ship/ by train/by bus/ by taxi/ by bike/ by minibus

　　2. Walking is good for health. 走路对健康有益。

　　Walk是动词，不能做主语。若要用walk做主语，就需在Walk后加—ing，即用walking做主语。动名词是动词的另一种非限定形式。它在句中起名词的作用，可单独使用或引起短语，做句子的主语、表语、宾语或介词的宾语。如：

　　Reading in bed is bad for you eyes.主语

　　My favourite sport is swimming.表语

　　Lily likes dancing.宾语

　　Thank you very much for helping me.介宾短语

　　Be good for 意为“对….有益”，与be bad for（对……有害） 相对。如：

　　Doing morning exercises is good for health.

　　Eating too much is bad for health.

　　3．Take the bus

　　take在句中是“乘，搭”的意思，表示一种行为。而“by+ 交通工具名词”则表示一种方式。如：

　　You can take the No.5 bus.

　　My mother often comes back home by bike.

　　4．总结交通工具

　　1．运用这个功能项目的主要起因：询问去某地、某处所的方式：

　　How do you come to school／go to work／go home for your holiday？

　　2．一般的交通方式（运用何种交通工具），可能取决于路途的远近、地理环境、经济条件等因素。

　　l）长途：by air / plane, by sea / ship, by train, by bus, by taxi, by car等。

　　短途：on foot, by bike, by bus, by taxi, by car, by boat, by minibus等。

　　2）地理环境

　　海：by sea／ship，by boat

　　陆：on foot，by bike，by bus，by minibus，by car，by taxi，by train等。

　　空：by air/plane

　　3）经济条件：可以比较国内不同地区的差异，中国与欧美国家人旅行方式的差异。

　　3．各种交通工具特点的比较。

　　by air / plane 与 by train

　　by air / plane: quick, save time, expensive

　　by train: take much time, cheap, safe, can see a lot.

　　Step 6．Homework
