将一个英语句子改为被动语态怎样改，有
语态→被动语态：1、找到该句宾语（是在谓语动词后的）,提子开头.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）.
如何把句子改成被动语态（英语）
their classroom are often cleaned by them after school.keys were often used by us for locking doors.主动句是指该句主语是谓语所表示的动作行为的发出者的句子。
被动句则是指该句主语是谓语所表示的动作行为的承受者的句子。
主动句和被动句互相转换的要点是主语和宾语的转换：主动句变被动句时，将主动句的宾语变为被动句的主语，主动句原来的主语与“被”构成介宾短语作被动句的状语；被动句变主动句则恰好相反。
? （四）主动句变被动句1.主动句变被动句第一步：要看时态，时态必须保持一致。
第二步：把主动句的宾语改为被动句的主语，谓语动词由主动形式改为被动形式，主动句的主语成为介词by的宾语，放在句尾。
For example:People keep sheep for producing wool.Sheep _______ ______ for producing wool _______ people.答案解析：在主动句中people 是主语，是动词keep动作的执行者，sheep就是keep的承受者。
在变被动语态时，把主动句中的宾语sheep变成被动句中的主语，主动句中的主语变被动句的宾语，其前加介词by。
谓语动词变过去分词。
故正确答案为：are，kept，by。
2．主动句改为被动句，要注意谓语动词由主动形式变为被动形式时的各种变化，具体有以下几种变化：一般现在时的被动语态：am\\\/is\\\/are + 过去分词一般过去时的被动语态：was\\\/were + 过去分词现在完成时的被动语态：have\\\/has +been + 过去分词情态动词的被动语态 ：can\\\/may\\\/must\\\/．．．+be + 过去分词一般将来时的被动语态：will\\\/shall +be + 过去分词现在进行时的被动语态：am\\\/is\\\/are +being + 过去分词过去进行时的被动语态：was\\\/were +being+ 过去分词 过去完成时的被动语态：had + been+ 过去分词接上面的：
