What is the Passive Voice?

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

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

Many students study English.(主动语态) 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。 The dictionary is well kept. 这本词典被保存完好(不需要说明是谁保存的) 。 2. 当我们需要强调动作承受者，而不是动作的执行者。 These book were found in the 1920s. 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）

被动语态的用法: 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. A note was passed up to the speaker.

The Structure is 助动词be+及物动词的过去分词 (be+P.P.)

被动语态的结构： 被动语态由“助动词be+及物动词的过去分词”构成，助动词be有人称、数的变化,其变化规则与be作为连系动词时一样。 如: The desk is made of wood. The desks are made of wood. He is asked a question by the teacher. I was given a nice present by my friend yesterday.
