被动语态
英语动词有两种语态,即主动语态(Active Voice)和被动语态(Passive Voice)。当主语为动作的执行者时,谓语的形式为主动语态;当主语为动作的承受者时,谓语要用被动语态。
Many people speak English.
English is spoken by many people.
主动语态,主语people是动作speak的执行者
被动语态,主语English是动作speak的承受者
一、被动语态的构成
被动语态是由“be +动词的过去分词”构成的。
助动词be随着主语的人称、数和时态的不同而变化。
二、一般现在时的被动语态
时态 被动语态结构 例句
主动语态 被动语态
一般现在时 am/is/are + 动词过去分词 We clean the classroom every day. The classroom is cleaned by us every day.
三、主动语态变被动语态的方法
We make this kind of machine in China.
→ This kind of machine is made by us in China.
主动语态: 主语 + 动词 +宾语
被动语态:主语 + be + 动词的过去分词 + (by + 宾语)
1. 将主动语态的宾语变为被动语态的主语;
2. 将主动语态的谓语动词变为“be+动词过去分词”结构;
3. 将主动语态的主语变为介词by后的宾语,放在谓语动词后面(如果不强调动作的执行者, 此介词短语常可省略)
被动语态肯定句的构成 主语+be+动词的过去分词(+其它)
被动语态否定句的构成 主语+________+动词的过去分词 (+其它)
被动语态一般疑问句的构成 ________+主语+动词的过去分词 (+其它)
被动语态一般疑问句的回答 肯定回答:Yes, 主语+be.
否定回答:No, 主语+be not.
be not
be
被动语态
的句子类型
肯定句:My bedroom is cleaned by myself.
否定句:My bedroom is not cleaned by myself.
一般疑问句: Is your bedroom cleaned by yourself?
特殊疑问句: Where is cleaned by yourself?
变为否定句:
把not放在be动词之后
变为一般疑问句:
把be动词放在句首
变为特殊疑问句:
特殊疑问词+一般疑问句
四、使用被动语态的情况
1. 不知道动作的执行者,或者没有必要指出动作的执行者是谁。
2. 需要强调或突出动作的承受者时。
3. 句子的主语是动作的承受者。
e.g. The blouse is made of silk.
The zipper is often used in our daily lives.
Tea is picked by hand.
结构:主动语态:主语+谓语+宾语
被动语态:
主语
be +过去分词
by+宾语
即:、主变宾、宾变主,谓语动词变被动。”
(注:主变宾即主语变为介词by宾语)
1. They often clean their classroom after school. (改为被动语态)
