主动语态与被动语.pptVIP

主动语态与被动语态英语中的语态有两种：主动语态（the active voice）和被动语态(the 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。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，或者只需强调动作的承受者时，要用被动语态。 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” 初中阶段主要掌握三种形式的被动语态：一般现在时态、一般过去时态、含有情态动词的被动语态。它们的结构分别是： 1.be(am,is,are)+过去分词 2.be(was,were)+过去分词 3.情态动词must/can/should/may+be+过去分词 主动语态变被动语态: 主动语态：主语 +谓语 +宾语+其他 被动语态：主语+be+过去分词+by+宾语+其他 被动语态专项练习 一、选择题 ( )1._____ a new library _____ in our school last year?
