Let's review

1.英语动词有两种语态，主动语态和被动语态。一.主动语态表示: 主语是动作的执行者.二.被动语态表示: 主语是动作的承受者
He cleans the living rm every day.
动作的执行者+ 动作 +动作的承受者
_____________
The living rm is cleaned by him every day.
动作的承受者+ 动作 + 动作的发出者
____________
_____
2.被动语态的基本构成： be（am, is, are)+动词的过去分词 ---（be+dne)
过去分词的用法也有两个特点：一是表示完成.二是表示被动.规则动词的过去分词在动词原形后加“ｅｄ”构成
三.过去分词只强调被动意思，表明动作已经完成.
1.规则动词的过去分词：
1)一般情况在动词原形后加-ed
watch---watched
2)以不发音e结尾的加-d
practice---practiced
3)以辅音加y结尾的，去y变i加-ed
4)以重读闭音节结尾，末尾只有一个辅音字母， 先双写该辅音字母，再加-ed
2.不规则动词的过去分词：
如何判定句子是主动 r 被动？
看主语是否是动作承受者
主动语态变被动语态的方法
（主语） （宾语）主动语态：动作的执行者+谓语动词的主动形式+动作的承受者被动语态：动作的承受者+谓语动词的被动形式+动作的执行者 （主语） （宾语）
说明：（1）要将主动句里的宾语变为被动句中的主语，若主动句中的宾语为人称代词，要将宾格变成主格。（2）把主动句中的主语变为被动句中的宾语，主格变宾格，并由by引导。（3)谓语动词变成相应的被动形式。
