语态也是动词的一种形式,表示主语与谓语之间的关系.英语有两种语态：主动语态和被动语态People .被动语态表示主语是谓语动作的承受者,.
(II)被动语态的构成
被动语态的形式是由“助动词be动词的过去分词”构成.助动词be随着主语的人称,数,时态和语气的不同而变化.各种时态的被动语态形式如下：
1.
注：Get＋过去分词也可以构成被动语态,用这种结构的句子侧重于动作的结果而不是动作本身.如：
the man got hurt on his way home. 那个男人在回家的路上受伤了.
)被动语态的几种句型
1.将主动语态中的宾语转换成被动语态的主语.
2.将主动语态中的动词改为“be+V(p.p)”
3.原来主动语态中的主语,如果需要,放在by后面以它的宾格形式出现,如没必要,可以省略.
4.主动语态中的其他句子成分不变.
由于主动语态结构的不同,因而转换成被动语态的方式也各有不同,现分类说明如下：
a.由及物动词形成的被动语态：
(1)S+V+O 主语+动词+宾语语法学习纲要由江苏省靖江高级中学外语组为英语猫网站编写
People grow rice in the south. Rice is grown in the south.
注：带有宾语从句的句子转换成被动语态时,需要将宾语从句变为主语从句,通常用形式主语来代替,而将主语从句后置.
They said that he would e back soon. It was said that he would e back soon.类似的还有：
It is reported / believed /hoped /supposed that ……
(2)S+V+O+C 主语+动词+宾语+宾补
We elected Li Ming monitor of our class. Li Ming was elected monitor of our class.
注：在主动结构中跟不带to的动词不定式作宾补变为被动结构时应加上to作主语补足语.
奴隶们被奴隶主强迫整日整夜工作.Slave-owners made slaves work all day and all night.
Slaves were made to work all day and all night by slave-owners.
(3)S+V+Oi+Od 主语+动词+间宾+直宾 语法学习纲要由江苏省靖江高级中学外语组为英语猫网站编写
昨天他给了我一件漂亮的生日卡.He gave me a beautiful birthday card yesterday. I was given a beautiful birthday card yesterday.
A beautiful birthday card was given to me yesterday.
注：用直接宾语作被动语态的主语时,通常要在间接宾语前加上适当的介词.如：to, for, of等,以加强间接宾语的语气.
b.由动词短语形成的被动语态：
一般情况下,只有及物动词才能跟宾语,而不及物动词不能跟宾语,所以只有及物动词才有被动语态,不及物动词则没有被动语态.但有些不及物动词后面跟上介词或副词后,变成一个动词短语,相当于一个及物动词,就可以形成被动语态.
约翰打开了收音机.John turned on the radio. The radio was turned on.
.
注：千万不要遗漏介词或副词.
c.祈使句的被动语态通常借助let句式
请把窗户关上.Please close the window. Let the window be closed.
(IV)被动语态的使用时机 语法学习纲要由江苏省中学外语组为英语猫网站编写
被动语态的使用往往不是任意的,而是按照表达思想,描述事物的需要,通常在下列情况下使用被动语态.
1.不知道或不必说出动作的执行者.
这本书已被翻译成许多种语言.This book has been translated into many languages.
2.动作的对象是谈话的中心.
我们家乡将建一条新铁路.A new railway will be built in our hometown.
3.修辞的需要,为了使句子更加简练匀称：
他出现在舞台上受到了观众的热烈欢迎.He appeared on the stage and was warmly applauded by the audience. 被动语态便于论述客观事实,故常用于科技文章,新闻报道,书刊介绍及景物描写.
【特别提醒】 有些动词后跟不带to的不定式作宾语补足语,但改为被动结构后要加上“to”.例如
We heard him sing in his room just now.
---He was heard to sing in his room just now.
刚才听到他在房间中唱歌.
