初中英语被动语态讲义VIP免费

1 被动语态讲义（一）（二） 被动语态（一） 一、基本知识。 英语动词有两种语态： 主动语态 (the Active Voice) 被动语态 (the Passive Voice) A. 主动语态表示主语是动作的执行者。 We planted the tree. B. 被动语态表示主语是动作的承受者。 The tree was planted by us. 汉语中常用“被”、“给”、“由”、“受”等词用来表示被动，而英语用助动词 be + 及物动词的过去分词（+by）构成。 (一)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。 (二)被动语态的基本结构: 被动语态由助动词 be+过去分词+by构成，当不想强调动作执行者时，by可省略，时态通过 be 表现出来。 be + 过去分词 2 注：后面能接宾语的动词才有被动语态 不同时态的具体结构： 1. 一般现在时：is / am / are + 及物动词的过去分词 Now English ____ by more and more people all over the word.
