三、本节课的学习要点及考点

重点句型：

1.allow 允许,常用于下列结构中,allow sb .to do sth,允许某人做某事,allow doing sth 允许做某事,be allowed to do sth ,被允许做某事.如:she allowed me to go fishing 她允许我去钓鱼.

We don’t allow smoking in the reading room .我们不允许在阅览室吸烟.

2.show 给….看如:show your tickets please,请出示你的票.

3.be made of/from 由…制成.be made of (看得出原材料)be made from (看不出原材料)如:the desk is made of wood .桌子是由木材制成的.

4.be used for被用做…. 如:pens are used for writing.钢笔被用来写字.

5.本句表达康康的主观臆想,不一定能实现,所以用情态动词could 像这种表示主观愿望和假想虚拟的语气叫虚拟语气.,多用于非真实条件句中,be的过去 式一般用 were表将来情况时主句中第一人称should ,其他人称用,would而从句中所有人称都用would,如:If I were you ,I would go 如果我是你就会去.If you loved me ,you wouldn’t say that.如果你爱我,就不会说那种话. 

6.be developed in .某物在某地研制  在这句话里省略了in,因 为in 的宾语是where而where 是副词,所以in省略,试比较which place is it made in?它是哪里制造的?因为宾语which place是名词短语所以不可省略in类似的还有what ate you looking for?你正在找什么?where do you live?你住在哪儿?which place so you live in? 你住在哪儿?

（二）.课堂探究

一般过去时的被动语态.

一、语态概述

被动语态表示主语是动作的承受者，即行为动作的对象。例如：The room was cleaned by Kangkang主语room是动词cleaned的承受者。

二、被动语态的构成

被动语态由"助动词was/were＋及物动词的过去分词"构成。人称、数和时态的变

化是通过be的变化表现出来的。

一般过去时：was／were＋spoken

三、被动语态的用法

 (1)不知道或没有必要说明动作的执行者是谁。

例如：Some new computers were stolen last night.　一些新电脑在昨

晚被盗了。(不知道电脑是谁偷的)

This bridge was founded in 1981.这座桥竣工于1981年。

 (2)强调动作的承受者，而不强调动作的执行者。

  例如：The glass was broken by Mike.玻璃杯是迈克打破的。

  This book was written by him.这本书是他写的。

四、主动语态变被动语态的方法

 (1)把主动语态的宾语变为被动语态的主语。

 (2)把谓语变成被动结构(be＋过去分词) (根据被动语态句子里的主语的

人称和数，以及原来主动语态句子中动词的时态来决定be的形式)。

 (3)把主动语态中的主语放在介词by之后作宾语，将主格改为宾格。例如：

All the people laughed at him.

He was laughed at by all people.

He cut down a tree.

A tree was cut down by him.

（三） 提高 拓展的练习

1. It ______ (make) of wood.

2. The desk ______ (use) for putting a computer on.

3. Paper _______ (make) from wood.

4. The PRC ______( found) in 1949.

5. Her book _____ (not throw) away yesterday.

1. is made 2. is used 3. is made 4. was founded 5. wasn’t thrown
