The passive voice.被动语态
英语中动词有主动和被动两种语态，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， 在被动语态中动作的执行者有时用by短语表示出来。
被动语态的构成:
助动词be+ (及物动词的) 过去分词
am (is, are) + done
was (were) + done
一般现在时
一般过去时
The passive voice.被动语态
被动语态的用法: 不知动作执行者时,常用被动语态.
e.g.. My bike was stolen yesterday.
This car is made in America.
2. 不必要说出动作执行者时,常用.
e.g.. Rome was not built in a day.
3. 为了突出强调动作的承受者时,常用被动语态.
e.g. Thousands of beaches are polluted (污染).
The passive voice.被动语态
主动语态变为被动语态的步骤:
1.把原主动句中的宾语转换为被动语态的主语。
2.把动词改为被动形式，即 “be + 过去分词”。注意 be动词要按新的主语的人称和数进行变化，时态要和原来的主动语态的时态保持一致。
3. 原来主动语态句中的主语，如果需要，就放在by后面以它的宾格形式出现。如果没有必要就可以省略。其他的成分 (定语，状语) 不变，句式也不能变。
Bell invented the telephone in 1876.
The telephone was invented by Bell in 1876.
