学科 英语 年级/册 九年级Unit 6 教材版本 人教版
课题名称 一般过去时的被动语态
难点分析 从知识角度分析为什么难 the passive voice of the past tense是对句型结构知识的一个重点考察，尤其是对如何找谓语动词、分析句子时态及动词过去分词的熟练运用做了一个综合性的考察，需要在语言知识的运用上做一个综合考量。
从学生角度分析为什么难 the passive voice of the past tense是学生第一次接触，语文里的“被”字句学生会变形，但英语的“被”字句对于学生来说是难点，尤其在谓语动词如何添加变为“被”字句，是中考的必考题型之一，要给学生讲透，会做并且达到灵活运用是难中之难，需要在多练中找到方法，让学生学会自己总结，才能在实践中出真知。
难点教学方法 通过展示学生的已知的电话、电视、电脑、车的图片及例句，列出发明的年代，再到拉链以及茶的发明来展示the passive voice of the past tense的句型，在复习中找到被动语态的句型结构，并进行总结。 根据总结出的被动语态结构，进行任务型教学，通过习题对基础的句型进行训练和灵活运用能力的提升，进一步夯实基础。 在最后的小结过程中，复现已知知识，再次夯实基础。 通过课后作业的布置，让学生拓展课外与发明相关的知识，做好课外知识的拓展延伸，让学生能对英语学习的兴趣保持一个长期相对稳定状态，以良好的状态去学习和应试。

So the order is the telephone, the car, the TV and the computer. Step 2: Presentation Use pictures and examples to show the structure of the passive voice of the past tense.
