(被动语态) ? ? 英语句子有主动语态和被动语态两种。 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。 ? 被动语态的句子是由: “be +及物动词过去分词(done)” ? ? 所有被动语态的句子理论上都可以还原成一个“主谓宾”结构的句子。 ? 被动语态常用在以下三种情况： ?1). 不知道谁是动作执行者 ? eg: His bike has been stolen. ?2). 没必要指出谁是动作的执行者 ? eg: I was told you were late this morning. ?3). 需要强调突出动作的承受者时 ?eg: The final decision has been made. ? ? 被动语态可用于不同时态当中，只需变化”be”的形式（其规则和be一样），过去分词(done)部分不变。疑问和否定也与be一样。 一般现在时被动: I am (not) told … 一般过去时被动: I was (not) told… 一般将来时被动: I will(not) be told… 现在进行时被动: I am(not) being told... 过去进行时被动: I was(not) being told… 现在完成时被动: I have (not)been told… 过去完成时被动: I had(not)been told … ? ? 一般现在时被动: am/is/are +done 一般过去时被动: was/were+ done 一般将来时被动: shall/will+ be done 现在进行时被动: am/is/are+being done 过去进行时被动: was/were+being done 现在完成时被动: have/has+been done 过去完成时被动: had +been done l 情态动词+ be+ done ? 被动语态的常见考点和难点： 1. 被动语态与不同时态的结合 ? 2. 一些动词短语，固定搭配也可以别为被动句，其实质不变。 eg: The teacher was listened to carefully. ??
