Unit 6 When was it invented?Section B 1a-2e教师寄语：Virtue never grows old. 美德永不老。学习目标：1、熟练掌握被动语态用法。2、学会用被动语态表达对创造和发明事物的认识和看法。教学重难点：主动语态被动语态1主动结构的宾语变为被动结构的主语；2主动结构的谓语动词由主动语态变为被动语态；3主动结构的主语变为介词by的宾语，组成介词短语，放在被动结构中谓语动词之后。在动作的执行者无须说明或不必强调时，by短语可以省略。4主动语态、被动语态两种时态要保持一致：We repaired the motor.The motor was repaired by us.教学过程：1.情境导入： Warm up:Ask the students to practice speaking.A: When was invented ?B: It was invented in A: Who was it invented by ?B: It was invented by A: What is it used for ?B: It is used for 2. 自主学习：Presentation.1) 教学helpful, annoyingAsk students to give some examples to show what each word means.

There are five people in the family .They are father, mother ,two daughters and a son . They have different ideas about which museum they want to go. At last, the clerk gives them some good advice.然后，我再让学生在播放听力前浏览第三个对话的句子，最后我才开始播放听力，这次学生们完成听力任务的效果
