前面已经讲过五大基本句型，不同句型转换成被动语态的形式也不同，现分类说明如下：
一、由及物动词形成的被动语态：
(1)S+V+O 主语+动词+宾语
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it来代替，而将主语从句后置。
They said that he would come back soon. It was said that he would come 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：在主动句中使役动词接动词原形作宾补，变为被动时应加上to。
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+IO+DO 主语+动词+间宾+直宾
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。
二、由动词短语形成的被动语态：
除了及物动词后面跟宾语，还有一些不及物动词后面跟上介词或副词后，变成一个及物动词短语，就可以形成用被动语态。
约翰打开了收音机。John turned on the radio. The radio was turned on.
奶奶照看我姐姐。Grandma takes care of my sister. My sister is taken care of by Grandma.
注：千万不要遗漏介词或副词。
三、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
