Unit 9 When was it invented？（Section A）一．语法：被动语态1.被动语态的时态: 被动语态的时态通过be的变化来体现，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。

Eg：This 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. 教室是三天前被打扫的.(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.教室应该每天都被打扫.2.被动语态的否定句和疑问句:（1）否定句的构成：必须在第一个助动词后加not。

Eg：His 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。

Eg：When 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。
