被动语态
The Passive Voice
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。被动语态由助动词be+过去分词构成,时态通过be表现出来。
二.被动语态的结构:
be + 过去分词 ( 及物动词 )
被动语态是英语动词的一种特殊形式 . 汉语中往往用 “ 被 ” “ 受 ” “ 给 ”等词来表示被动意义 .
三.主动语态变为被动语态的方法 :
1 . 主动句中的宾语变成被动句的主语 .
2 . 主动句中的谓语动词变成被动句的 be + 过去分词 .
3 . 主动句中的主语变成被动句 by 的宾语 , 放在谓语动词后面 . 如果不强调动作执行者时 , by 短语可省略 .
