定义：英语中有两种语态，主动语态和被动语态。主动语态句子的主语是谓语动词动作的发出者，被动语态句子的主语则是动作的承受者。这种语法结构相当于中文的“被”字句。
“把”字句 I eat apples every day. → “被”字句 Apples are eaten by me every day.“把”字句 Students lve this bk. → “被”字句 This bk is lved by students.通过观察发现，句子中原本的谓语动词“d”变成了“be dne”的形式。被动语态句子中，谓语部分的基本结构为 be + dne，其中be为助动词，dne是动词的过去分词，被动语态和主动语态一样，有人称和时态的变化。

二、一般过去时的被动语态

三、一般将来时的句式总结
