七、被动语态的各种时态
被 动 语 态
一、概念:
语态是动词的一种形式,用于说明主语和谓语之间的关系。英语中的语态有两种:主动语态(Active Voice)和被动语态(Pasive Voice)。主动语态表示主语是动作的执行者;被动语态表示主语是动作的承受者。被动语态中的执行者可由介词by引出。
二、什么情况用被动语态:
1.动作谁做的不知道;没必要知道动作的执行者.
2.动作的承受者需强调.
3.当动作的执行者不是人而是无生命的事物时。如:
Many houses were destroyed by the flood.
三、构成:
被动语态由“助动词be+及物动词的过去分词”构成即be+done
其中的助动词be有人称、数和时态的变化。
一般现在时态的被动语态各种句式如下:
句 式 构 成 例 句
肯定句 主语+am/is/are+及物动词过去分词+其他。 English is widely used all over the world
否定句 主语+am/is/are+not+及物动词过去分词+其他。
一般疑问句 Am/Is/Are+主语+及物动词过去分词+其他
English is not widely used all over
the world.
Is English widely used all over
the world
Mary broke the cup.
The cup
如:
三步走
step1:
主动句中先找出主语、谓语动词、宾语;
把主动句的宾语变成被动句的主语;
step2:
把主动句的谓语变成“be+过去分词”,be时态与原句保持一致;
step3:
把主动句的主语变为by的宾语,放在被动句的谓语之后,by短语可以省略。

主语
谓语
宾语

by Mary.

四、主动语态变被动语态
宾变主,主by宾,谓语动词be+done.
①Mike returned the book to the library.
The book was returned to the library by Mike.
②My father bought me a watch yesterday.
A watch was bought for me by my father yesterday.
例题:
主语
谓语
宾语
buy sb. sth.
/buy sth. for sb.
给某人买某物


主动语态转换成被动语态
五、使用被动语态应注意的几个问题:
1.不及物动词(短语)没有被动语态如:happen,rise,appear,come out,take place等。
2.动词短语如talk about,pay attention to,look after,take
care of等在变被动语态时其中介词不能省略。
3.在主动语态的句子中,感官动词和使役动词后面接省掉to
的不定式做其宾补时,在变被动语态时要加上。如see,make等(共10个词)
4.有些动词表示主语(多为物)的某种性质而非人为的原因时
做不及物动词,无被动形式。如:sell,write,ride,draw
These books sell well.
5.连系动词如sell,taste,sound,look等用主动表被动。如:
The food smells good.
6.当含有双宾语的动词变被动语态时,若间接宾语人做主语时,一切照旧;
若直接宾语物做主语时,则需在间接宾语前加to或for。如give,buy等。
