16、nd passive：动作的接受者the office 成了句子的主语，就应该用被动语态。从上面的例句我们可以总结：一般现在时的被动语态为：主am / is / are （not）过去分词一般过去时的被动语态为：主was / were 过去分词如： butter is made from milk. this house was built 100 years ago. 以前我们学过的was / were born 生于，就是一个被动语态born 是个过去分词（bear）when were you born ? i was born in 1989. 如果要特别强调动作或行为的执行者，句子后面

17、需接by ，译为“被（由）”如： we were woken up by a loud noise . 我们被嘈杂的声音吵醒。（2）现在进行时被动语态的构成为主语 is / am / are + being 过去分词再如：my car is being repaired now. some new houses are being built near the park. 公园附近在建一些房子。（3）现在完成时被动语态的构成为主语 have / has been 过去分词如：my key has been stolen. my keys have been stolen. i am not g

18、oing to the party , i haven t been invited. 含有情态动词的被动语态情态动词 be过去分词a note had better be left to him. teenagers should be allowed to wear their own clothes 精品学习资料 可选择p d f - - - - - - - - - - - - - - 第 4 页，共 7 页 - - - - - - - - -精品学习资料 可选择p d f - - - - - - - - - - - - - - 第 4 页，共 7 页 - - - - - - - - -

19、这里我们列举了几个主要时态，那么其它时态呢？一般将来时主语 will be 过去分词过去将来时主语 would / should + be 过去分词过去进行时主语 was / were + being 过去分词过去完成时主语 had + been +过去分词被动语态的时态是由be 的时态决定的， be 是什么时态，全句就是什么时态，be动词后面的过去分词不变。归纳：肯定句：主语be + 过去分词（by ）否定句：主语be not 过去分词（by ）一般疑问句：be 主语过去分词（by ）? 特殊疑问句：疑问词be主语过去分词（by ）3. 被动语态的用法：（1）不知道或没有必要说明动作的执行者

20、是谁，不用by动作执行者短语such books are written for children. 这些书是为儿童写的。i havent been told about it . 没有人告诉我这件事（2）强调动作的承受者，这时应用by 短语。the cup was broken by david. （3）作客观说明时，常采用一种被动语态句型its / was said / believed / reported / + that its reported that about three hundred people were killed in this earthquake. 据报道，这

21、次地震中大约有三百人死亡。4. 主动语态变为被动语态把主动语态的句子变为被动语态的方法是：（1）把原句中的宾语变为主语（2）动词改为被动形式，即be+过去分词（3）原来的主语，如果需要的话，放在by 后面，如果没必要，可省略。注意事项：主动语态变成被动语态应注意事项从主动语态到被动语态的过程中主语、谓语动词、宾语都发生变化。注意主格与宾格的变化形式。注意主语的人称及数的变化对be 动词带来的影响。注意 be 动词的时态形式取决于原主动语态的动词时态形式。5. 被动语态的几种类型（1）有两个宾语的句子的被动语态（直接宾语，间接宾语）常见的接双宾语的动词有通常这种句子可以改为以“人”当主语；和以“

22、物”当作主语的两种被动语态。如： he gave me a book. 精品学习资料 可选择p d f - - - - - - - - - - - - - - 第 5 页，共 7 页 - - - - - - - - -精品学习资料 可选择p d f - - - - - - - - - - - - - - 第 5 页，共 7 页 - - - - - - - - -i was given a book by him. （以 i 做主语）a book was given to me by tom. （以物 book 作主语）he teaches us english. we are taught e

23、nglish by him. （以人当主语）english is taught us by him. （以物作主语）（2）含有宾语补足语的句子的被动语态keep, make 三类的动词常常有宾语补足语，在被动语态中，宾语补足语位置不变。we keep food fresh in the fridge. 主谓宾宾补food is kept fresh in the fridge. i saw him go into the office building. he was seen to go into the office building. 英语中有“十大动词”的说法，即feel , hear

24、 , listen , have , make , let , look , watch , see , notice ，这些词在主动句中，其后的动词不定式不加to，但变被动句时必须加to. （3）含有短语的主动语态变被动语态不及物动词没有宾语，因此没有被动语态。但有的不及物动词后面加上介词及其他一些词类构成短语动词之后，其作用相当于及物动词，可以接宾语，因而也可以变为被动语态。在变成被动语态时，不能去掉构成短语动词的介词或副词they take good care of my child. my child is taken good care of 他们把我的孩子照顾得很好。i turne

25、d off the radio. the radio was turned off （by me）附：动词短语的被动语态take care of be taken care of cut down be cut down laugh at be laughed at look after be looked after 下列这些短语本身即是被动语态的形式，不需再加by be covered with 用覆盖着be interested in 对感兴趣be surprised at 对感到惊奇be made of （from ）用制造的（4）由情态动词形成的被动语态含有情态动词的句子在变为被动语态时，在情态动词后面加上be 动词
