当我们不知道谁是动作的执行者, 或者没有必要指出谁是动作的执行者时, 或者只需强调动作的承受者时, 要用被动语态。 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

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. The boss made him do the heavy work in the old days.

4. Tom must hand in the composition after class. Conclusion: (二)

主动语态如何改成被动语态？

1. 主动语态的宾语改成被动语态的主语。

2. 主动语态的谓语动词改成被动语态的谓语动词。 do→be done 3. 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. English is widely used nowadays.
