初中英语被动语态讲解及练习(共22张PPT)

Passive Voice 被动语态 英语动词有两种语态：主动语态和被动语态。 1.当我们不知道谁是动作的执行者, 2. 或者只需强调动作的承受者时，要用被动语态。 被动语态结构： be + 过去分词(PP) + (by …) 表格：被动态基本结构 am/is/are done was/were done (shall/will/be going to) be done have/has been done 时态 被动语态结构 一般现在时 一般过去时 一般将来时 现在进行时 am/is/are being done 现在完成时 情态动词的被动语态 情态动词+ be + done must be done/mustn’t be done should be done/ shouldn’t be done can be done/ can’t be done may be done/ might be done 各种时态的被动语态构成 1）一般现在时：You are invited to do this. 2）一般过去时：The story was told by her. 3）一般将来时：The problem will be discussed tomorrow. 4)情态动词：The rubbish can be put into the dustbin over there. 在改写中应注意： 1.把原来的宾语提到前面作被动语态的主语; 2.把动词变成“be + 过去分词”; 3.主动语态中的主语变为介词by的宾语。 Many people speak Chinese.
