1927JohnBaird1.被动语态定义被动语态表示主语是动作的承受者。如：ThetelephonewasinventedbyBellin1876.2.被动语态的构成被动语态由“助动词be+及物动词的过去分词“构成。

助动词be有人称、数和时态的变化，其变化规则与be作为连系动词时完全一样。如：(1).Itwasinventedin1876.(2)Theyareusedforlisteningtomusic.3.被动语态的用法当我们不知道谁是动作的执行者或者没有必要指出谁是动作的执行者，或者只须强调动作的承受者时，要用被动语态，如：EnglishisspokeninCanada.Grammar:Thepassivevoice(被动语态）1.Myjacketismadeofcotton.一般现在时的被动语态的谓语结构：be（现在式）+动词过去分词一般过去时的被动语态的谓语结构：be（过去式）+动词过去分词2.Stampsareusedforsendingletters.3.Itwasbuiltin1380.4.Itwasmadeofstoneandmetal.5.Itwasusedfortravelling.Thepassivevoice.被动语态主动语态变为被动语态的步骤:把原主动句中的宾语转换为被动语态的主语.2.把动词改为被动形式,即“be+过去分词”.注意be动词要按新的主语的人称和数进行变
