初中英语被动语态复习
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:
He opened the door.他打开了这扇门。(主动语态)
The door was opened.这扇门被打开了。(被动语态)
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,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:
 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)


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:
 注意:如果主动句的宾语是代词,需将其由宾格变为主格。如:
 Tom killed him. → He was killed by Tom.
 (2)将动词改为"be+过去分词"。
 注意:
 They held a meeting yesterday. → A meeting was held by them yesterday.
 他们昨天开会了。
 (3)将主动语态的主语改为be…放在谓语动词后。
 注意:如果原主语是代词,则应由主格变为宾格。
 He sang a song. → A song was sung by him.
2、主动语态变为被动语态的注意事项:
  含有双宾语,即直接宾语(常指事物)和间接宾语(常指人)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.
四、下列动词(词组)没有被动式:
1.、 系动词无被动语态:以主动形式表示被动之意

① be动词
