文档介绍：Passive Voice 被动语态
中考说明:
★掌握一般现在时、一般过去时、一般将来时和带有can,may,must等情态动词的被动语态的构成和基本用法。
被动语态基本用法
当句子的主语是动作的执行者时,谓语的形式是主动语态。当句子的主语是动作的承受者时,谓语要用被动语态。被动语态由助动词be+过去分词构成,时态通过be表现出来。
巧记主动语态变被动语态顺口溜
主动变被动,划分句子成分主、谓、宾首先用,接着判断时态巧布控,主动谓语变被动,be+过分来使用。
宾语变主语,主语by宾语,谓语be+过分随时态记。
情态动词主动变被动,情态动词+be+过分一起用。
双宾物作主,指人宾语前要带for或to.
使役、感官动词后,宾补动词别忘加to用。
其余部分不变化,抄下完整句子好说话。
