Unit9 When was it invented? Section A主动语态与被动语态：英语动词有两种语态,即主动语态(The Active Voice)与被动语态（The Passive Voice)。
主动语态表示主语是动作的执行者/ 被动语态表示主语是动作的承受者e.g. 1. They make trains in Zhuzhou . 主动语态Trains are made in Zhuzhou. 被动语态2.The farmers grow cotton every year. 主动语态Cotton is grown by the farmers every year. 被动语态一：被动语态的构成:助动词be+ (及物动词的) 过去分词am (is, are) + done 一般现在时was (were) + done 一般过去时二: 主动语态变为被动语态的步骤:1.把原主动句中的宾语转换为被动语态的主语.2.把动词改为被动形式,即“be + 过去分词” . 注意 be动词要按新的主语的人称和数进行变化,时态要和原来的主动语态的时态保持一致.3. 原来主动语态句中的主语,如果需要,就放在by后面以它的宾格形式出现. 如果没有必要就可以省略.其他的成分 (定语,状语) 不变, 句式也不能变.主动语态变被动语态的结构图:Bell invented the telephone in 1876.主语谓语动词过去时宾语时间状语The telephone was invented by Bell in 1876主语谓语动词的过去分词宾语时间状语三：被动语态的特殊用法:（一）：双宾语 buy/make sb sth=buy/make sth for sbgive sb sth=give sth to sb1.My father bought me a computer.A computer was bought for me by my father.I was bought a computer by my father.2. He gives me a book. A book is given to me by him. I am given a book by him （二）、无to不定式变为被动时加上to一感feel 二听listen to.hear♣三让let.have.make四看watch. see. look at. notice♣eg. We often see him play basketball. He is often seen to play basketball by us. （三）、注意动词短语的完整性The baby is taken good care of by the nurse（四）、无被动语态的动词。

《Unit 9 When was it invented Revision》
一．学习目标：
1.复习单词及词组
2.巩固被mind-map of the information you find. Then give a report to the class.
重难点1. 掌握被动语态的各种时态
二. 知识链接
复习各种时态的被动语态。
并总结和归纳。
五. 合作探究
英语的语态分主动语态和被动语态两种。
主动语态的主语是动作的执行者；被动语态的主语是动作的承受者。
eg. We use a knife for cuttin g (主动句).
A knife is used for cutting (被动句)。
一、构成：be + 过去分词
eg. 1)The work is f inished by him.
2)Chinese is spoken by people in China.
二、被动语态的时态
1.一般现在时：am/ is/ are + 过去分词
eg. English is spoken by E nglishmen.
2.一般过去时：__________________
eg. The machines were made in China.
3.一般将来时: __________________________
eg. A sports meeting will be held in our sch o ol next week.
4.现在完成时：_______________________
eg. The work has been done by them.
5.现在进行时：________________________
eg. A new school is being built in our village.
6.过去进行时：_____________________
eg. My TV set was being mended at that time.
综上所述：被动语态的时态只涉及be动词的变化（即：be动词的各种时态）
另外注意几点：1.含情态动词的被动语态：
can / may / must / should + be + 过去分词
eg. He m ay be sent away from school.
2.带动词不定式的被动语态
eg. My bike needs to be mended.
3.在使用被动语态时，如需要指出动作执行者时，应用“by + 动作的执行者(宾格)”
2. Main phrases。
