(1)把间接宾语改为被动语态的主语，直接宾语仍保留原位。如：[文章版权 禁止转载:考试与评价 http://www.trgroup.com.cn/te/ 4q .OuBi1G?AT:E%FroG]
He gave the boy an apple. → The boy was given an apple.[文章版权 禁止转载:考试与评价 http://www.trgroup.com.cn/te/ X?*F*SswAL 4NrfA=8FroG]
Her father bought her a present. →She was bought a present by her father.[文章版权 禁止转载:考试与评价 http://www.trgroup.com.cn/te/ W@F)y8'))26"rZS2/}xFroG]
(2)把直接宾语改为主动语态的主语，此时，间接宾语前要加介词to或for。如上两句可改为：[文章版权 禁止转载:考试与评价 http://www.trgroup.com.cn/te/ 4vc=+g/z�s?@ S2P9PRFroG]

3. 带复合宾语的动词在改为被动语态时，一般把主动语态的宾语改为主语，宾语补足语在被动语态中作主语补足语。如：[文章版权 禁止转载:考试与评价 http://www.trgroup.com.cn/te/ ?S3tc{ 5L^:&?U *[$LFroG]
We should keep our room clean and tidy. →Our room should be kept clean and tidy.[文章版权 禁止转载:考试与评价 http://www.trgroup.com.cn/te/ +[F@18,n,bxYhFroG]
提醒：不带to的动词不定式作宾语补足语的主动语态，改为被动语态时不定式前要加to。如：[文章版权 禁止转载:考试与评价 http://www.trgroup.com.cn/te/ ^/2{v8`Zr*~oFroG]
I heard the girl sing in the next room. →The girl was heard to sing in the next room.[文章版权 禁止转载:考试与评价 http://www.trgroup.com.cn/te/ �!+"tp[R?k7w_ewM;VFroG]
4. 动词短语的被动语态：动词短语在主动结构中是一个不可分割的词组，在被动语态结构中也是如此，不可丢掉后面的介词或副词。如：[文章版权 禁止转载:考试与评价 http://www.trgroup.com.cn/te/ 5tM toYXy^VnD!FroG]
The nurse takes good care of the child. →The child is taken good care of by the nurse.[文章版权 禁止转载:考试与评价 http://www.trgroup.com.cn/te/ D#?v 0q .Kd[fRbJFroG]
5. 含有宾语从句的被动语态：如果主动语态结构中，宾语是从句，变被动语态时，一般用it作形式主语，真正的主语放在后面。可以转换的动词有know， say， believe， find， think， report等。如：[文章版权 禁止转载:考试与评价 http://www.trgroup.com.cn/te/ ^:q&PqHL{3UM"ds} R?rFroG]
