思考：
1) 被动语态结构有何规律？
2) 被动语态句中主语是动作的执行者还是承受者？
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
肯定句 主语+_____________+动词的过去分词(+其它).
否定句 主语+_____________+动词的过去分词 (+其它).
一般疑问句 __________+主语+动词的过去分词 (+其它)
一般疑问句的回答 肯定回答：Yes, 主语+am/is/are.
否定回答：No, 主语+am/is/are not.
am/is/are not
Am/Is/Are
一、被动语态的构成
被动语态是由“助动词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。
一般现在时被动语态结构如下：
am/is/are
二、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；(注意人称代词的主格、宾格变化)
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)。
三、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. 被动语态多用于正式文体中。
4. 有些表达习惯上常用被动语态。
e.g. It is reported that ... 据报道……
It is said that ... 据说……
It is well-known that ... 众所周知……
It is believed that ... 大家相信……
