被动语态详解与练习

1、被动语态详解与练习英语动词有两种语态：主动语态 (the Active Voice) 被动语态(the Passive Voice)A. 主动语态表示主语是动作的执行者。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.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 y

2、esterday. 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)（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） 助动词be+及物动词的过去分词一般现在

3、时： am / is / are done一般过去时： was / were done现在进行时： am / is / are being done过去进行时： was / were being done现在完成时： have / has been done过去完成时： had been done一般将来时： shall/will be done ; be going to be done当句中含有情态动词时，句子结构为 can / must / have tobe done2)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
