1、Unit 5 What are the shirts made of?,第三课时 (Grammar Focus4c)单元同步语法精讲精练,一般现在时的被动语态 语态的概念：在英语中有主动语态和被动语态两种语态。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。 eg：We speak English.我们讲英语。(主动语态) English is spoken by us.英语被我们讲。(被动语态) 一般现在时的被动语态：表示现在发生的动作或存在的状态，主语是动作的承受者。 结构： 肯定句：主语be(am/is/are)及物动词的过去分词其他 否定句：主语be(am/is/are
2、)not及物动词的过去分词其他 一般疑问句：Be(Am/Is/Are)主语及物动词的过去分词其他？ 特殊疑问句：特殊疑问词一般疑问句？ eg：The desk is made by him.这张桌子是他做的。 The desk isnt made by him.这张桌子不是他做的。 Is the desk made by him？这张桌子是他做的吗？ Where is the desk made by him？这张桌子是他在哪儿做的？,主动语态变为被动语态 主动语态的宾语变为被动语态的主语； 主动语态的谓语动词变为“be及物动词的过去分词”形式； 主动语态的主语变为by引导的短语放在主谓结构之
