被动语态(Passive Voice)
一、概述：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执行者。被动语态表示主语时动作的承受者。
口诀：主动、主动、主去动；被动、被动、主被动。
二、构成：被动语态由“助动词be+及物动词的过去分词”构成。人称、数和时态的变化通过be的变化来体现。
口诀：被动语态be字变，过去分词跟后面。
eg. Many people speak English.（主动语态）
→English is spoken by many people.（被动语态）
★一般过去时的被动语态：
结构：主语+was/were+动词的过去分词
e.g. The bridge was built in 1996 by them.
They were invented by Edison.
