文档简介
1、英语动词有两种语态,即主动语态(the Active Voice)和被动语态(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。如:English is spoken by many people. 当我们不知道或没必要提到动作的执行者是谁或者强调突出动作的承受者时,常用被动语态。 (1)一般现在时的被动语态(2)一般过去时的被动语态(3)一般将来时的被动语态 (4)一般现在时带情态动词的被动语态考点一 被动语态的构成 被动语态由“助动词be +及物动词的过去分词”构成。助动词be 有人称、数和时态的变化,其变化规则与be作为连系动词时完全一
