被动语态讲解
语法点拨
一、被动语态概述
语态是动词的一种形式，用以说明主语与谓语动词之间的关系。英语的语态共有两种：主动语态和被动语态。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。被动语态是动词的一种特殊形式，一般说来，只有需要动作对象的及物动词才有被动语态。汉语往往用“被”、“受”、“给”等词来表示被动意义。如：
They didn’t offer Ann the job. （主动语态）
Ann wasn’t offered the job. （被动语态）
安没得到这份工作。
二、被动语态的构成
被动语态由“助动词be+及物动词的过去分词”构成。被动语态的时态变化只改变be的形式，过去分词部分不变。疑问式和否定式的变化也如此。
1、被动语态的时态较常见的八种形式
现以动词clean为例列表说明：
2、被动语态的句式变化：
以一般现在时和动词invite为例，列表说明被动语态的句式变化：
3、含有情态动词的被动语态
情态动词的被动语态结构为：情态动词+be+过去分词；其时态及句型的变化仅由情态动词完成，“be+过去分词”部分不变。如：
中共党史
Tables can be made of stone. 桌子可由石头制造。
Tables could be made of stone at that time. 那时桌子可由石头制造。（一般过去时）
Can tables be made of stone? 桌子能用石头制造吗？（疑问句）
三、被动语态的用法：
1、不知道或没有必要指出谁是动作的执行者。
The old bridge was built many years ago. 这座古桥是许多年前建造的。
He was elected chairman.他被选为主席。
2、强调动作的承受者。
动作的执行者由by引导置于谓语动词之后，也可省略。
Your plan is considered to be the best. 你的计划被认为是最好的。
3、动作的执行者是无生命的事物。
The window was blown by wind.窗户被风吹开了。
The whole village has been washed away by the flood.整个村庄都被洪水冲走了。
4. 避免更换主语，如：
Once a promi is made, it shouldn’t be broken. 诺言一旦许下，就不能违背。
Mothers love their children and children are sure to love their mothers.
母亲爱孩子，孩子当然也爱母亲了。
5. 使句子保持平衡，如：
The lecture will be made by Joe Smith, who is a young artist from the States.
乔史密斯将来做报告，他是一位年轻的美国艺术家。
（Joe Smith有一个非限定性定语从句，所以后置）
四、主动语态变为被动语态
转换图示：
1、主动语态变为被动语态的步骤：
（1）将主动句的宾语变为主语，如果主动句的宾语是代词，需变为主格。如：
（2）将动词改为“be+过去分词”，be与新主语的人称和数一致，时态不变。
（3）将主动语态的主语前加by放在谓语动词后，如果原主语是代词，要变为宾格。
They held a meeting yesterday. → A meeting was held（by them）yesterday.
他们昨天开会了。 昨天举行了一个会议。
They won’t forgive me. → I won’t be forgiven by them.
他们不会原谅我的。 我不会被他们原谅的。
2、主动语态变为被动语态的注意事项：
（1）主动句中的主语如果是people, we, you, they, somebody等含糊地表示“人们”、“大家”等，
变为被动句时，通常删去“by…”，除非强调原主语。如：
They t up this hospital in 1975. → This hospital was t up in 1975.
这所医院建于1975年。
Only he can finish the job. 只有他能完成这项工作。→
The job can be finished only by him.这项工作只能由他来完成。
（2）含有双宾语，即直接宾语和间接宾语的句子，每个宾语都可变为被动语态的主语，即其被动语态
有两种形式。但多以间接宾语作主语。
Jack told us the truth.杰克告诉了我们真相。
We were told the truth by Jack.
The truth was told (to) us by Jack.
（3）含有宾语+宾语补足语的句子，变成被动句后原来的宾语补足语就成了主语补足语了；
注意：不带to的不定式作宾语补足语时，变成被动时要加上to。
I heart Emily sing the song just now.
→ Emily was heard to sing the song just now.
我刚才听见艾米莉唱这首歌了。
（4）含有宾语从句的主动句变为被动句，通常用it作为被动结构的先行主语，把宾语从句后置。
We have determined that the plan should be carried out soon.
It has been determined that the plan should be carried out soon.
我们决定这项计划必须马上实施。
（5）双重被动结构：
当某人或物成为两次动作的承受者时，要用双重被动结构。如：
Parents often ask their children to do too much homework.
The children are often asked to do too much homework.
Too much homework is often asked to be done by the children.

六、高频考点：
1. 动词的主动形式表示被动之意
1）某些连系动词，如：look, feel, smell，sound, prove等。
一句心情签名
The flower smells sweet.这花闻起来很香。
Maria proves very patient and warm-hearted. 玛丽亚被证明很耐心、很热心。
2）表示主语内在“品质”或“性能”的某些动词，虽然可以是及物动词，但这时用作不及物动词，
如：lock, shut, clo, open, move, read, write, ll, wash, clean, draw, cut,
translate, burn, run, ride, begin, end, operate等。
The ntences translate hard. 这些句子很难译。
The door won’t shut. 这个门关不上。
3）某些动词用在句型“主+谓+主补”时，如wear，blow，prove等。
The door blew open. 门被吹开了。借来的幸福>宝宝书包
