4、作的对象。巧记为：被动、被动、主被动。 例如：English is spoken by many people. 主语English是动词speak的承受者。,一般现在时被动语态的构成： 肯定：主语+is/am/are+过去分词+其它+（by+主动语态句子的主语） 否定：主语+is/am/are+not+过去分词+其它+（by+主动语态句子的主语）,(1)把主动语态的宾语变为被动语态的主语。,三、主动语态变被动语态的方法,We often use a recorder in our English class.,宾语,A recorder is often used in our Englis
5、h class （by us）.,主语,(2)把谓语变成被动结构(be过去分词) (根据被动语态句子里的主语的人称和数，以及原来主动语态句子中动词的时态来决定be的形式)。,We often use a recorder in our English class.,谓语,A recorder is often used in our English class （by us）.,一般现在时的被动语态,(3)把主动语态中的主语放在介词by之后作宾语，将主格改为宾格, 如主语是人称代词，一般省略。 They make the bikes in the factory.,The bikes are
6、made （by them ）in the factory.,4.在主动语态句中动词make、have、let、see、watch、hear、feel等后接动词不定式作宾语补足语，动词不定式不加to。但变成被动语态时后面的不定式都须加上to。 例如： (1)The boss makes them work ten hours a day. (2)Tom lets his little sister water flowers every day.,They are made to work ten hours a day.,His little sister is let to water f
7、lowers every day by Tom.,5.含有双宾语的句子，主动句中的间接宾语或者直接宾语都可变为被动语态中的一个主语，另一个保留不变。变为主语的若是主动句中的直接宾语在变为间接宾语前则需加介词to 或for。 常用双宾语的动词：show/give/offer/send /bring/ lend /teach/buy 例如： The teacher gives the pupils some advice.,The pupils are given some advice by the teacher.,直接宾语,间接宾语,Some advice is given to the p

10、情态动词变被动，情态加be加“过分”，原来带to要保留。 例如：,1.We can repair this watch in two days. 2.You ought to take it away. 3.They should do it at once.,This watch can be repaired in two days.,It ought to be taken away.,It should be done at once.,.选择填空: 1.
