The classrm was cleaned yesterday. 教室昨天被打扫了。(被动语态，主语the classrm是clean这一动作的承受者)
Grammar

am / is / are + 动词的过去分词

Grammar
Alexander Graham Bell
the telephne
主动句变为被动句所遵循的4个步骤：1. 把原主动句中的宾语变为被 动句的主语。2. 把动词变为被动形式，即be+ 过去分词，并注意其人称和 数随主语的变化，而动词的 时态则保持不变。3. 原主动句的主语如需要则放 在by后面以它的宾格形式出 现（注意代词的宾格），如 不需要则可省略。4. 其它的成分（定语、状语） 不变。
口诀：主宾互换格要变 谓语变化时态定by加被动宾语前其他一律都不变
①含有双宾语的主动句变为被动语态时，通常把 指 “人”的间接宾语变为主语，而指“物” 的直接宾语则不变。►He gave me a bk yesterday.→I was given a bk (by him) yesterday.②如果要把指“物”的直接宾语变为主语，则在 间接宾语前加t或fr。►I brught him sme fd. →Sme fd was brught t him (by me).
③含有复合宾语的主动句变为被动语态时，要将 其中的宾语变成主语，宾语补足语不变。►Jim asked Tm t g fr a walk.→Tm was asked (by Jim) t g fr a walk.④如果宾语补足语是不带t的动词不定式，主 动语态变成被动语态时要加上不定式符号t。►We ften heard Kate sing in the rm. →Kate was ften heard t sing in the rm (by us).
