111学习目标：扎实掌握被动语态的用法，提高具体语境中灵活运用的能力。学习难点：学习被动语态的用法。、概述1语态是动词的一种形式，用来说明主语和谓语的关系。英语的动词可分为主动语态(active voice)和被动语态(passive voice)。主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。主动语态和被动语态可以相互转化。She typed a letter. (主动，主语She是type动作的执行者)A letter was typed by her.（被动，主语A letter是typed动作的承受者）Granny takes care of the girl. (主动，主语Granny是take care of动作的执行者)The girl is taken care of by Granny. （被动，主语The girl是take care of动作的承受者）2被动语态的使用范围（1）不知道或没必要指出动作的执行者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时。这时不用by短语。This jacket is made of cotton. 这件上衣是棉料的。English is spoken in Canada. 加拿大讲英语。（2）为了强调动作的承受者时Visitors are requested not to touch the exhibits.要求参观者不可触摸展品。The store is run by the trade union. 这家店是工会办的。The song was composed by a student. 这首歌是一个学生谱写的。（3）出于策略、委婉、礼貌等不提出动作的执行者You are said to be active recently. 据说你最近很活跃。The plan was generally considered not practical. 普遍认为这个计划不实用。Its said that he would come back soon. 据说他很快就会来。常用于如下短语：Its not known that 不得而知 Its said that 据说Its reported that 据报道 Its not decided that尚未决定Its believed that 据认为 Its announced that据宣布 3、应用时态： 时态动词形式一般现在时一般过去时一般将来时现在进行时过去进行时现在完成时过去完成时过去将来时 4、注意事项：情态动词的被动形式 不定式的被动语态(有些情况则由主动表被动) 短语动词的被动语态 有的被动形式则表示状态而非被动之意 过去分词作状语时，及物动词表被动，（无需be动词）不及物动词表完成，动名词的被动语态。.
