如果主语是动作的承受者，或者是说动作不是由主语而是由其他人完成的，则用被动语态。主动语态→被动语态：
1、找到该句宾语（必须是在谓语动词后的），将它提到句子开头。
2、用被动语态结构be+Vt过去分词构成句子。
3、把原句的主语用by构成的介词短语带出，也可不加。
eg：I finished my homework yesterday.
→My homework was finished (by me) yesterday.
特殊形式：
1、部分Vi加上适当介词可当作Vt构成被动语态。
eg：Parents look after their children carefully.
→Children were looked after (by parents) carefully.
2、联系动词没有被动语态。eg：The water feels warm.
3、在主动语态中一些省略to的动词不定式改为被动语态时需加上to。
eg：Teachers often make him stand outside.
→He is often made to stand outside (by teachers).
4、have、let等动词无被动语态。
必要时，have可改为held，let sb to do sth可改为be allowed to do sth (被允许做某事
