What is the Passive Voice?

英语动词有两种语态： 主动语态 (the Active Voice) 被动语态 (the Passive Voice) What is it? A. 主动语态表示主语是动作的执行者。 B. 被动语态表示主语是动作的承受者。 We planted the tree. The tree was planted by us.

We speak English. 主语谓语宾语 English is spoken by us. 主语谓语宾语 主动语态 被动语态

当主语是动作的执行者时，动词用主动语态 （ Active Voice ）；如果主语是动作的承受者， 动词便用被动语态（ Passive Voice ）。 We cleaned the classroom yesterday. 昨天我们打扫了教室。 The classroom was cleaned by us yesterday. 昨天教室被我们打扫了。 Many students study English.( 主动语态 ) English is studied by many students.( 被动语态 )

When to use it? 1. 当我们不知道谁是动作的执行者，或没有必 要指出谁是动作的执行者时。 2. 当我们需要强调动作承受者，而不是动作的 执行者。 这本词典被保存完好 ( 不需要说明是谁保存的 ) 。 这些书是在二十世纪二十年代发现的。 （强调书被发现而不是强调由谁发现） The dictionary is well kept. These book were found in the 1920s.

被动语态的用法 : A note was passed up to the speaker. 1. 强调动作的承受者 ; 如 :Table tennis is played all over China. English is spoken by many people. 2. 不需要指出动作的执行者或动作的执 行者难以说出或不必说出. 如 :Another bridge has been built across the Changjiang River. The Party was founded on July 6,1924.

在改写中应注意： 原宾语主语 ; 1. 把原来的宾语提到前面作被动语态的主语 ; be + 过去分词 2. 把动词变成 “be + 过去分词 ”; 主语 by 宾语。 3. 主动语态中的主语变为介词 by 的宾语。 典型题例 例 1 将下列句子改为被动语态。 We clean our classroom every day. Our classroom is cleaned (by us) every day.
