Unit 25 The accident,标签:八年级英语教案模板,http://www.89xue.com

  2. Some students are drawing pictures on the blackboard.

  3. The boys from Class 3 are playing basketball on the playground.

  4. A dog is running after a bus.

  5. A bird is flying high in the sky.

  让学生快速把以上句子改成否定句和一般疑问句,并作肯定和否定回答,说出其变换的规律。接着启发学生思考过去进行时应如何变换。根据学生回答的情况,老师进行具体指导。在这以后,老师请同桌的两人为一组,一个同学写一句过去进行时的肯定句,另一个紧接着写一句否定句。

  例如:

  1. I was doing my homework last night. I wasn’t watching TV.

  2. Li Ming was listening to English at eight o clock yesterday.

  3. He wasn’t writing a diary.

  4. My mother was doing some washing this time yesterday. She wasn’t doing some cooking.

  也可以一个先说否定句,另一个说肯定句。例如:

  1. My English teacher wasn’t writing a letter last night. He was looking over the student’s exercises.

  2. They weren't having classes this time yesterday. They were planting trees.

  3. I wasn’t doing the cleaning yesterday afternoon. I was doing some shopping.

  这样操练既加深了学生对过去进行时否定式的理解,同时也锻炼了他们的口语表达能力和快速思维能力。

  在讲解过去进行时的一般疑问句时,可采用A、B、C三人一组的方法,先设定一个表示过去特定时间的状语,at 9:00 yesterday morning。A在做坐自行车的动作,B问C:

  Was he(she)riding a bike at 9:00 wt morning?

  C回答:Yes,he was.

  接着B又问C:Was he mending a bike?

  C回答:No,he wasn’t.

  这样操练既形象,又生动,学生感兴趣。

  阅读训练

  本单元第98课安排了一篇阅读短文。短文叙述了一次交通事故及一群学生和他们的老师在交通事故中所表现出的那种助人为乐、认真负责的良好品德。文中出现的单词不多,估计学生阅读困难不大,在整个阅读过程中我们可以分三部分进行。

  1.阅读前的活动(Pre-reading)

  先让学生看课文中的插图,初步了解课文所叙述的主要内容。老师在黑板上写好阅读提纲。(1)At the school gate. (2) Hearing the sound of the motorbike. (3) At the gatekeeper's room. (4) At the library.

  2.阅读中的活动(While-reading)

  教师可以提出问题。如:

  1) What happened when the children were leaving school?

  2) What did the children do when they saw a bag fall off the truck?

  3) What happened to the man on a motorbike?

  让学生带着问题阅读课文,寻找答案。并鼓励学生提出课文中的疑难问题,老师答疑。这样做教师的讲解有的放矢,学生印象深刻,更重要的是启发学生思考,开发学生的思维能力。

  3.阅读后的活动(After-reading)

  阅读完了以后,听学生简要回答老师提出的问题,检查他们的阅读效果。接着放录音,让学生跟读、模仿,以改进语音语调。鼓励学生朗读时带有感情,朗读完后老师可以有重点的讲解一些重要词组和短语,如come round the comer,fall off,not…until,be badly hurt等,如果时间允许的话可以做练习册把课上练习1。

  能力训练建议

  1.本单元的语法重点是过去进行时的否定形式和疑问形式,学生不能死记硬背它的结构,而应与一般现在进行时进行比较,在比较中加以掌握和理解。

  2.本单元动词短语较多,可以把动词短语分类记忆,牢记核心点,结合语境记忆、掌握。例如可在对话中运用“You’d better ride a bike instead of a motorbike.”“You’d better pick up the waste paper around you.”“If you see someone have a little accident, don’t crowd round him.”
