詹大悲中学初三英语导学案: Unit 9 When was it invented?〔Section A

1.预习sectionA的主要知识点〔请学生务必根据自己的学习情况自由补充!!〕 被动语态小结:

1.被动语态的时态: 被动语态的时态通过be的变化来表达,它必须与主语的人称、数一致。以下是几种常用的被动语态:

(1)一般现在时的被动语态: am / is / are + 动词的过去分词。

EgThis book in two languages.这本书是用两种语言写的. (2)现在进行时的被动语态: am / is /are + being + 动词的过去分词。 Eg: A school is by the workers now.工人们正在建一所学校. (3) 一般将来时的被动语态: will / be going to + be + 动词的过去分词. Eg: The project will next month.这项工程下个月就完工. (4) 现在完成时的被动语态: have / has + been + 动词的过去分词. Eg: My homework .我的作业以完成了. (5) 一般过去时的被动语态: was / were + 动词的过去分词.

Eg: The classroom three days ago. 教室是三天前被清扫的. (6) 含有情态动词的被动语态: 情态动词 +be +动词的过去分词.

The classroom every day.教室应该每天都被清扫. 2.被动语态的否认句和疑问句:

1〕否认句的构成:必须在第一个助动词后加not

EgHis homework finished. 他的作业还没有完成。 2〕疑问句的构成:将第一个助动词置于主语之前。

EgWhen the bridge ?这座桥是何时建的? 3、主动语态变被动语态的方法:

1 把主动语态变的宾语作为被动语态的主语

2 主动语态的谓语改成be + 过去分词的形式,作为被动语态的谓语,be随着主语以及时态的变化而变化。

3 主动语态的主语变为by的宾语,有时可以省略。 Eg He often plays computer games Computer games are often played by him

4、被动语态的注意方法:

1 在主动句中动词makelethaveseehearfeelwatchfind notice等后接不定式作宾补时,动词不定式都要去掉to,但变被动语态时,后面的不定式须加to. make sb. do sth. sb. be made to do sth. eg: The man made the boy do his homework.. The boy was made to do his homework.

hear sb. do sth. sb. be heard to do sth. eg: I often hear him sing in the next room. He is often heard to sing in the next room.

(2) 主动语态中假设有双宾语,变为被动语态时,只将其中一个宾语变为被动句的主语,另一个宾语不.一般情况下,往往把表示人的宾语变为被动句的主语,而把直接宾语〔物〕留作被动句的宾语。如果把主动句的直接宾语变为被动句的主语,那么间接宾语常须有介词〔一般是forto eg My mother bought me a bike. 其被动句为:

I was bought a bike by my mother. = A bike was bought for me by my mother.

(3)有些词如系动词taste, feel, look, smell, sound ,以及 sell “销量(好坏)〞讲时常用主动语态表达被动的意思.

Eg: This song sounds gentle. 这首歌听起来轻柔.

Many kinds of books sell well. 许多种类的书销量不错.

(4)有些词,happen=take place “发生, belong to “属于,〞没有变动语态. Eg: The necklace belongs to me. 这个项链属于我.

2. 本单元要掌握的句型 见课本P69 中的Grammar Focus

give sth. to sb. 如:I gave a pen to him. 我给他一支笔。 give sb. sth. I gave him a pen. 我给他一支笔。 6. all day 整天

7. salty adj. 咸的 salt n. 8. by mistake 错误地 如:
