在英语中，动词有两种语态，即主动语态和被动语态。
一、被动语态
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。
e.g. Many people speak English.
（主动语态, 句子的主语many people是
动作speak的执行者）
English is spoken by many people.
（被动语态, 句子的主语English是动作
speak的承受者）
被动语态由“助动词be+及物动词的过去分词”构成。与主动语态一样，被动语态也有时态、人称和数的变化, 其变化规则与be作为连系动词时完全一样。
二、被动语态的构成
3.主动语态变为被动语态的方法
第一步:主动语态的宾语—被动语态的主语；
第二步:将主动语态的谓语改为“be+及物动词的过去
分词”结构；
第三步:将主动语态的主语改为介词by的宾语，放在
谓语之后(有时可省略)。
如图示：
They (主语）grow (谓语）tea (宾语）in the south-east of China.
被动语态:
主动语态:
Tea (主语）is grown (谓语）by them in the south-east of China.
被动语态的几种句型
1. 肯定句 主语 + be + 过去分词 + (by…)
A sweet song is sung by her on the stage.
2. 否定句 主语 + be + not +过去分词 + (by…)
3. 一般疑问句 Be + 主语 +过去分词 + (by…)
A sweet song isn’t sung by her on the stage.
Is a sweet song sung by her on the stage
4. 特殊疑问句 疑问词 + be + 主语 +过去分词 + (by…)
