We bought a book yesterday. The book was bought yesterday. 2)主语+谓语动词+间接宾语+直接宾语将主动语态中一个宾语变为被动语态的主语.多数情况下将间接宾语变为主语.如果直接宾语变为主语时.间接宾语前要加介词to / for. 多数情况下将间接宾语变为主语.如果直接宾语变为主语的化.间接宾语前要加介词to / for He showed me a book yesterday.

He was found a good pupil. 4)短语动词变为被动语态有些短语动词相当于一个及物动词.其后可以接宾语.因此它们也有被动语态.但短语动词是不可分割的整体.变为被动语态时不可去掉其后面的介词或副词. We should look after the patients very well. The patients should be looked after very well by us. 5)宾语从句变为被动语态若主动语态中是宾语从句.变为被动语态时常用it作形式主语.而把真正的主语放在后面. It’s said that he passed the exam. 被动语态应注意的几个特殊问题: (1)不及物动词带介词和介词宾语.在变为被动语态时.仍然要带上介词. The students in class listen to the teacher carefully. The teacher is listened to carefully by the students in class. (2)当动词带有复合宾语时.并且宾补是省去“to 的动词不定式时.在被动语态中应加上“to . They make do all the work.
