（一）主语与动词的关系：主动语态主语是动作的执行者，被动语态主语是动作的承受者。

（二）被动语态的基本结构：be

+

done（动词的过去分词）

一般现在时态的被动结构：am

/is

/are

+

/were

+

be

+

done

情态动词的被动结构：情态动词+

be

+

done (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。

Your homework must be finished on time. 你们的家庭作业必须及时完成。

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. They make the bike s in the factory . The bikes are made by them in the factory. 五

、含有情态动词的被动语态

含有情态动词的主动句变成被动句时,由"情态动词+be+过去分词"构成,原来带to的情态动词变成被动语态后"to"仍要保留。

We can repair this watch in two days.[来源:Z.xx.k.Com] This watch can be repaired in two days. 六、特殊情况 (一)含有双宾语的动词的被动语态：含有双宾语的主动句改为被动句时,应将其中一个宾语改为被动结构的主语,另一个宾语仍保留在原处。一种情况是把间接宾语(指人)变为主语,直接宾语(指物)不变。另一种情况是把直接宾语(指物)变为主语,间接宾语(指人)不变,这时,间接宾语前通常加介词to,有时

加for。如:My father gave me a new book on my birthday.→

I was given a new book (by my father) on my birthday. (间接宾语作了主语) A new book was given to me (by my father) on my birthday. (直接宾语作了主语) （二）带有复合宾语的动词的被动语态：

带有复合宾语(宾语和宾语补足语)的主动语态变为被动语态时,只把宾语变为被动语态的主语,原来的宾语补足语不动。同时,如果宾语补足语是省略to的动词不定式,变为被动语态时,必须加上不定式符号to,这类动词有make, let, see, hear, watch等。

如:I often hear him sing i n his room.→He is often heard to sing in his room. （三）有的动词的主动形式可以表示被动意义,这类动词有: wash, sell, smell, taste, sound, feel等。

如:1）The books sell well. 2） The food tastes good. 课堂检测：（见导学案）
