Book 2 unit 3 computers-- learning about language

导入：回顾旧知识

The classroom is cleaned by students everyday. My bike was stolen last night.

一．语态：语态时动词的一种形式，用来说明主语跟谓语动词的关系，

英语分为两种语态。

主动语态：

主动语态表示主语是动作的

_____。We planted the tree.

被动语态：被动语态表示主语是动作的

_______。The tree was planted by us.

一般说来，只有需要动作对象的及物动词才有被动语态。

二．被动语态构成：be +及物动词的过去分词（be+done)

三．被动动态的使用：

(1)不知道

或没必要说出

动作的执行者时，用被动语态。

The old bridge was built many years ago.这座古桥是很多年前建造的。

He was elected chairman. 他被选为主席。

(2)强调动作的承受者，此时动作的执行者由“by+动作的执行者”跟在be +done 后面，也可省略。

This good was asked by the monitor.

四．主动变被动的方法：

1.被动句的主语：将主动句的宾语变成被动句的主语

2.被动句的谓语：将主动句的谓语动词改为“be+done”

3.被动句的宾语：将主动句的主语前加by 放在谓语动词之后。

如：they held a meeting yesterday.

A

meeting was held (by them)yesterday.

主动语态变被动语态的注意事项：

1)在“主语+谓语(pass,lend,buy,write,bring, show,tell...)+间接宾语+直接宾语”句型中，最好把间接宾语变成被动句的主语；

若把直接宾语变成被动句的主语，则需在间宾前加to/for.

E.g.

She gave me a book.（直宾：_____;间宾：______;)

I was given a book by her.

A book was given to me by her.

.His mother told him a story.

He

____ ____

a story by his mother . 或

A story

___

___ ____him by

1

his mother. .He often lends me a pen.

I ___

often ____a pen by him.

或

A pen __ often ____

____ me by him.

2). 动词短语的被动：不能分割，必须将其看作一个整体，不可漏掉介词或副词。

如：They take good care of the baby.

The baby is taken good care of by them.

五：必修2中三种时态的被动语态

初中已学习过一般现在时、一般过去时、情态动词的被动语态,今天我们将接着学习一般见来时，现在完成时和现在进行时的被动语态

一般将来时

主动语态
