被动语态：主语是动作的承受者 被动语态的构成：be +动词过去分词 如果要特别强调动作或行为的执行者时句子后面需接by…，译为“被（由）……” 各个时态的被动语态被动语态的否定句和疑问句主动语态如何改成被动语态？小测试：请把下列句子转换成被动语态 1. Many people speak English. 2. He bought me a new bike yesterday. 3.

2. 主动语态的谓语动词改成被动语态的谓语动词 do→be done3. 注意保持时态和人称的一致4. 带双宾的谓语动词有两种改法当把直接宾语改成主语时，谓语动词后必须加适当的介词: to 或 for.如: give → be given to 此类动词还有: pass, show, send… 再如: buy → be bought for 此类动词还有: make, draw, cook, mend…5. 一些动词不定式在主动语态中省略to作宾语补足语, 改成被动语态时, to必须还原注意：1. 不及物动词（vi.) 不用被动语态如:happen、take place 、appear、disappear…例句：A traffic accident _________ (happen) just now.2. 连系动词(Link.v.)不用被动语态如: be、look、seem、feel、sound、smell、taste、get、turn、become… 例句： Peking Opera _________ (sound) beautiful.3. 当此动词表示事物的自然属性的时候，不用被动语态 。
例句： The pen _____ (write) very fast. This kind of sweater ____ (sell) well.被动语态的其他注意事项 ：1.适合被动语态的情况 不知道谁是动作的执行者，或由于某种原因没有必要指出谁是动作的执行者时 例句：This jacket is made of cotton. The book was written for children.需要突出或强调动作的承受者时 例句：Food is needed by every living thing.
