一、概念
英语的语态是通过动词形式的变化表现出来的。英语中有两种语态：主动语态和被动语态。主动语态表示主语是动作的____________；被动语态表示主语是动作的____________，即行为动作的对象。
执行者
承受者
二、被动语态的构成
被动语态由“be动词＋及物动词的过去分词”构成。人称、数和________的变化是通过be动词的变化表现出来的。英语中最常用的被动语态有三种：
(1)一般现在时的被动语态：am/is/are＋done。如：
I am often praised by the teachers.
我经常受到老师们的表扬。
时态
(2)一般过去时的被动语态：was/were＋done。如：
I was asked to go to Harbin on business yesterday.
昨天我被派往哈尔滨出差了。
(3)一般将来时的被动语态：shall/will be＋done。如：
The sports meeting will be put off.
运动会将被推迟。
三、“一变二套三注意”。
(1)一变：
变主动为被动或变被动为主动时，把原句的________和________互换，注意被动语态的构成是“be＋动词的过去分词”。如：
We planted a tree yesterday. →A tree was planted yesterday by us. 昨天我们种了一棵树。
主语
宾语
(2)二套：
被动语态的构成为“be＋动词的过去分词”。在不同的时态中，过去分词保持不变，而be动词随着时态有不同的变化，如：am/is/are(一般现在时)＋done；was/were (一般过去时)＋done；shall/will be(一般将来时)＋done等。若含有情态动词，则用“情态动词＋be＋动词的过去分词”结构。如：
Homework must be finished first. 家庭作业必须先被完成。
(3)三注意：
1）句中含有双宾语，如give/buy sb. sth. 时，一般要把主动句中的间接宾语(sb.)变成被动句的主语，若将直接宾语(sth.)变成主语，则在间接宾语前加上介词to或for。常用介词to的动词有give, show, pass, hand, lend, send 等；常用介词for的动词有borrow, buy, make 等。如：
The eraser was passed to me at last.
最后，橡皮被传给了我。
2）主动句中若谓语含有介词或副词的动词短语，变为被动句，介词或副词不能________。常见的词组有listen to, take care of, pay attention to 等。如：
We often talk with the old politely.
→The old are often talked with politely by us.
我们经常有礼貌地和老人说话。
省略
3）主动句中作________________的可省略to的动词不定式变为被动形式时要加上to。常见的词组有hear/see sb. do sth., make sb. do sth.等。如：
We made the boy stand outside.
→The boy was made to stand outside by us.
我们让这个男孩在外面站着。
