Passive voice（被动语态） 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。 被动语态的句型 被动语态的肯定句 主语 + be + 过去分词 + (by ...). e.g. The child is well loved by people. 这个孩子很招人喜爱。 People in the world are influenced by Confucious’ thoughts. 世界上的人们受到孔子思想的影响。 被动语态的否定句 主语 + be not + 过去分词 + (by ...). e.g. Mark Twain isn’t known as a great thinker. 马克·吐温并不是作为伟大的思想家而闻名于世。 The battery wasn’t charged yesterday. 电池昨天没有充电。 被动语态的一般疑问句 Be + 主语 + 过去分词 +（by ... ）? eg.
