The trees are watered by them every day. 主动语态 被动语态 执行者 承受者 承受者 执行者 Grammar 被动语态 Presentation: 被动语态的基本结构:be + done (p.p.)+ (by …) be有各种时态的变化 其否定形式为 be+not+done（过去分词） 被动语态要说明动作的发出者就加上by+sb（被某人，由某人） 过去分词 后面能接宾语的动词才有被动语态 Presentation: 动词过去分词的变化: 1.规则动词的过去分词： 1)一般情况在动词原形后加-ed watch---watched 2)以不发音e结尾的加-d practice---practiced 3)以辅音加y结尾的，变y为i加-ed 4)以重读闭音节结尾，末尾只有一个辅音字母，先双写该辅音字母，再加-ed stop---stopped drop---dropped 英语重读闭音节就是闭音节中为重读音节的音节，重读闭音节中元音字母不是发它本身的字母音，而是发短元音。 study---studied Presentation: 如何将主动语态换为被动语态 步骤1：把主动语态中的宾语转换为被动语态的主语 步骤2：把主动语态的谓语动词改为被动形式 （be＋过去分词) 注意：（1）人称和数要随着新的主语而变 （2）时态保持不变 步骤3：主动语态的主语，变为被动语态的宾语，改为“by+宾格”形式 步骤4：其他成分（定语、状语）保持不变 Presentation: Make sentences with the passive voice after the example.
