被动语态
一、被动语态概述
语态是动词的一种形式,用来说明主语和谓语动词之间的关系。英语动词有两种语态: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。一般来说,只有及物动词才有被动语态。
二、各种时态的被动语态的构成
使用被动语态的句子,谓语动词的形式是“be+动词过去分词”。人称、数和时态的变化规则与系动词be相同。几种常用时态的被动语态构成如下:
一般现在时:am/is/are+动词过去分词
一般过去时:was/were+动词过去分词
一般将来时:will/shall be+动词过去分词或am/is/are going to be+动词过去分词
现在进行时:am/is/are being+动词过去分词
过去进行时:was/were being+动词过去分词
现在完成时:have/has been+动词过去分词
过去完成时:had been+动词过去分词
English is taught in most schools.
大多数学校都开设英语课。
Their wedding was held in their hometown.
他们的婚礼是在他们家乡举行的。
Do you think the book will be reprinted
你觉得这本书会重印吗
He knew he would be punished for it.
他知道自己会为此受到惩罚。
注意 含有情态动词的被动语态:情态动词+be+动词过去分词。
Such work can be done in an hour or so.
这样的工作可以在一个小时左右做完。
三、主动语态变为被动语态的方法
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,时态不变。
3.有时把主动语态中的主语放在介词by之后做宾语,原做主语的人称代词要用宾格。
A sudden loud noise from nowhere woke me up in the early morning.
→I was woken up by a sudden loud noise from nowhere in the early morning.
They were building the new bridge.
→The new bridge was being built (by them).
We haven’t told her about it yet.
→She hasn’t been told about it yet (by us).
四、使用被动语态的场合
1.当不知道或没有必要指出谁是动作的执行者时,多用被动语态。
The bridge was built last year.
这座桥是去年建造的。
2.当更加强调动作的承受者时,多用被动语态。动作的执行者由by引导置于谓语动词之后,不需要时可以省略。
The room hasn’t been cleaned yet.
房间还没有被打扫。
3.当动作的执行者不是人时,多用被动语态。
The whole village has been washed away by the flood.
整个村庄都被洪水冲走了。
五、主动形式表示被动意义的几种常见情况
1.某些连系动词,如look,sound,smell,feel,taste,prove要用主动形式表示被动意义。
The garden looks very beautiful.
这个花园看上去很美。
2.某些与can’t,won’t等连用的不及物动词,如move,lock,shut,open。
The door won’t shut.
这门关不上。
3.某些可和well,easily等副词连用的不及物动词,如read,wash,clean,cook。
The cloth washes well.
这种布料好洗。
