英语中有两种语态。即主动语态 (The Active Voice)与被动语态（The Passive Voice)。
主动语态表示主语是动作的执行者；被动语态表示主语是动作的承受者.
We speak English everyday.
English is spoken by us everyday.
主动语态: 表示主语是动作的执行者.
被动语态: 表示主语是动作的承受者.
Many people speak English.
主动句与被动句之间的转换:
English is spoken by many people.
主语 谓语动词主动语态 宾语
主语 谓语动词被动语态的过去分词 介词+ 宾语
被动语态的基本结构:be + done (p.p.)+ (by …)
be有各种时态的变化
其否定形式为 be+not+done（过去分词）
被动语态要说明动作的发出者就加上by+sb（被某人，由某人）
过去分词
后面能接宾语的动词才有被动语态
图解助记:
有关be made...的短语:
主动变被动的方法:
总结:
主动语态 被动语态
宾语 →
谓语 →
主语 →
其他 → 抄下来
主语
be+ P.P(过去分词)
by +宾语
1.They make shoes in that factory.
主语+及物动词+宾语

一般现在时的被动语态：

肯定式 否定式 疑问式
一般 现在时 I am asked … He / She is asked … We/You/They are asked … I am not asked… He / She is not asked… We/You/They are not asked … Am I asked …
Is he/she asked …
Are we/you /they asked …
被动语态的句式
动词过去分词的变化:
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
study---studied
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
stop---stopped
drop---dropped
英语重读闭音节就是闭音节中为重读音节的音节，重读闭音节中元音字母不是发它本身的字母音，而是发短元音。
2.不规则动词的过去分词：
如：am/is/are______ was/were_____
have/has_____ do_____
go_______ write______
eat____ leave_____
drink______ take_____
break______ speak______
steal______ see______

bring______ know______
had

taken
broken

given
gotten/got

规则动词的过去分词的构成规则与规则动词的过去式的构成规则相同。部分不规则动词的过去分词形式也和过去式一样。
