语态是动词的一种形式，用来说明句中主语和谓语动词的关系。如果主语是动作的执行者，则使用主动语态；如果主语是动作的承受者，则使用被动语态。
被动语态有“be动词 + 过去分词”构成，如果要特别强调动作或行为的执行者时，句子后面需接by ...，译为“被/由”。其中be动词要根据人称、数和时态发生变化、be动词后面的过去分词不变。
被动语态的肯定句：主语 + be + 过去分词 + (by ...).
被动语态的否定句：主语 + be nt + 过去分词 + (by ...).
被动语态的一般疑问句：Be + 主语 + 过去分词 +（by ... ）?
被动语态的特殊疑问句：疑问词 + be + 主语 + 过去分词 +（by ... ）?
