study

English.(主动语态)English

isstudied

bymanystudents.(被动语态)语态被动语态的结构

助动词be+过去分词

(be+done)主动语态变被动语态的变法：口诀：宾变主，主变宾，谓变bedone,时不变，数格必须随被变。注：1.主动、被动的时态要一致。

2.主动、被动的句式要一致。

3.变成的被动语态的主语与谓语在单复数上保持一致。(四)主动语态变被动语态:(1)把主动语态的宾语变为被动语态的主语;(2)把主动语态的谓语动词变成被动语态的被动结构(be＋过去分词)(根据主动语态句子的时态，以及被动语态句子的主语来决定be动词的形式)。(3)把主动语态中的主语放在介词by之后作被动语态的宾语，将主格改为宾格。如：

They

make

thebikesinthefactory.

Thebikesinthefactory.aremadethemby主变被步骤:1.找宾语:即动作的承受者(改为主语)He

washed

hiscaryesterday.

Hiscar3.判断新主语的单复数:确定be动词的单复数.be4.判断动词的时态:即be动词的时态.2.修改谓语的语态:即be+原V.过去分词

washed5.修改原句的主语:即by+主语(变宾格).
