中考二轮专题复习课件 被动语态

课件33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 …)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。表格：被动态基本结构am/is/are donewas/were doneam/is/are being donewas/were being doneshall/will/be going to be donewould be donehave/has been donehad been doneSome people attacked the towers.
