2、n by many people. 主语 English 是动词 speak 的承担者;例如: He opened the door. 他开了门; 主动句 The door was opened. 门被开了; 被动句 二、被动语态的构成被动语态由“be及物动词的过去分词” 构成;不及物动词本身没有被动语态;及物动词 - 本身意义不完整,后必需带宾语,有些仍可以带双宾;不及物动词 - 本身意义完整,不需要带宾语,如带宾语必需通过介词;人称、数和时态的变化是通过be 的变化表现出来的;现以eat 为例说明被动语态在各种时态中的构成;一般现在时: amis are eaten 一般过去时: was
3、wereeaten 一般将来时: will/shall/be going to be eaten 过去将来时: would/should/be going to beeaten 现在进行时: amis are beingeaten 过去进行时: was were being eaten 现在完成时: havehas been eaten 过去完成时: had been eaten 歌诀是:被动语态 be 字变,过去分词跟后面;三、被动语态的用法 1 不知道或没有必要说明动作的执行者是谁;例如: some new computers were stolen last night. 一些新电脑在昨
