(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/ g ;MH:Ss. `l{H*z.rFroG]
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/ YA 7o A~=Q|?Jg%& OFroG]

(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/ g$�jDa.pR+36O4-FroG]

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/ USH%D +]YFroG]
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/ iT]^#1FA:MvJw/ 0FroG]
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/ zyz3*\k O':A _XiFroG]
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/ Z;cb}~;1i}h-gS@ jFroG]
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/ _K?rO@E r72 o n*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/ ?PcgBu*[*smPzFroG]
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/ ^�E2l|6%~ s8 g BrFroG]
