. Welcome ！ The Passive Voice made by Achilles（Mr. Peng） Grammar The Passive Voice 被动语态 主动语态与被动语态： 英语中有两种语态，即主动语态 (The Active Voice)与被动语态（The Passive Voice)。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。例如： They make trains in Zhuzhou. （主动语态） Trains are made in Zhuzhou. （被动语态） 一般现在时的被动语态构成： am / is / are + 动词的过去分词 主动语态变被动语态的步骤： 1. 主动语态的宾语变为被动语态的主语； 2. 主动句的谓语动词变为被动结构； 3. 主动句的主语变为被动句的宾语，由by引 出，当不强调动作的执行者时，常省略。 例如： Many people speak English. English is spoken by many people. 将下列的句子改为被动语态。 1. They speak English in Canada. 2. People use wood for making tables. 3. They make computers in the USA. 4. They grow rice in South China.
