学习目标：被动语态的构成，主动语态变被动语态转换

学习重难点：主动语态与被动语态的转换

一、1. 语态是动词的一种形式，表示主语和动词之间的关系。英语动词有两

种语态：主动语态和被动语态。主动语态动词的主语是动作的执行者，而被动语态动词的主语是动作的承受者。

2. 由助动词be + 及物动词的过去分词（V-ed）构成。

助动词be有人称、数和时态的变化。

二、 主变被解题步骤:

1. 找宾语 ----即动作的承受者

2. 判断宾语的单复数 ----即be动词的单复数.

3. 判断动词的时态 ----即be动词的时态.

4. 修改谓语的时态 ----即原句动词改为过去分词

5. 修改原句的主语 ----即by+ 主语/ 宾语.

Eg. They make shoes in that factory

Shoes are made in the factory by them.

一般现在时：am／is／are＋taught

一般过去时：was／were＋taught

一般将来时：will／shall (be going to) be＋taught

现在进行时：am／is／are being＋taught

过去进行时：was/were being＋taught

现在完成时：have／has been＋taught

含情态动词： can/ must/need/have to…+be taught

三、 语态转换(Give the students some minutes to discuss)

1. He teaches English in our school.

English is taught in our school by him.

总结：______________________________

2. She gave me a book.

I was given a book by her.

A book was given to me by her.

总结：_______________________________

3.He made me do the work

I was made to do the work by him.

总结：这些动词真奇怪，主动句中to 离开，被动句中to回 来。（feel,listen to,hear,let have,make,look at,see,watch…)

4.They take good care of the baby.

The baby is taken good care of by them.

注意：含动词词组的被动语态，须将其看作一个整体，不可把它们分隔开来。
