被动语态复习教学设计

1. 被动语态基本用法
当句子的主语是动作的执行者时，谓语的形式是主动语态。当句子的主语是动作的承受者时，谓语要用被动语态。被动语态由助动词be+过去分词构成，时态通过be表现出来。

6. (一)语态转换时要注意的问题
1. 把主动语态变为被动语态时，其谓语动词的时态要与原句时态保持一致，其谓语动词的数要与新主语保持一致。
We have bought a new computer.
A new computer has been bought. (正确)
A new computer have been bought. (错误)
2. 含有双宾语的主动句变被动句时，可分别将其中的一个宾语变为主语，另一个不动，一般变间接宾语为主语时比较多。
My uncle gave me a present on my birthday.
I was given a present on my birthday.
如果把直接宾语(指物)改为主语，则在间接宾语(指人)前加适当的介词，如上句还可以说： A present was given to me yesterday.
注意：一般在下列动词后，常在间接宾语前用介词 to，如：
tell , give, lend, offer, pass, show，promise, sell, , teach, bring等。
The cup with mixture was showed to the class.
My bike was lent to her.
一般在下列动词后，间接宾语前用介词 for, 如：
buy, ,make，cook, choose, fetch, get, order, 等。
Mother made me a new skirt. (A new skirt was made for me. )
The meat was cooked for us.
3. 感官动词和使役动词的被动语态
即feel , hear , listen , have , make , let , look , watch , see , notice ，这些词在主动句中，其后的动词不定式不加to，但变被动句时必须加to.
I saw him play basketball last Sunday.
We heard them sing in the classroom
4. 由动词+介词或副词构成的短语动词，变被动语态时，要把它们作为整体看，即把它们看成一个及物动词，介词或副词不可拆开或去掉。这类动词有laugh at,look at, look for,turn on(off), wait for, take care of等
eg: They laughed at her.
She was laugh at (by them).
5.不能用于被动语态的动词：如have, like , take place , belong to ，begin,sell,feel,smell,taste,feel…）
如：
I like these flowers. 我喜欢这些花。
I will have a meeting.
不说A meeting will be had. 应说A meeting will be held .
