10、物动词的过去分词+其他. 例句：The telephone was invented by Bell.否定句：主语+ was/were not+及物动词的过去分词+其他.例句：We are not allowed to be late for class.一般疑问句：Was/Were +主语 +及物动词的过去分词+其他?例句：Were the T-shirts designed by the man?被动语态的用法：1. 不知道谁是动作的执行者，或没有必要指出谁是动作的执行者。 例如：English is spoken all over the world. 全世界都在说英语。2. 需要突出或

11、强调动作的承受者。 例如：This dictionary is used by most students.这本字典是大多数学生在用的。主动语态变为被动语态的注意事项：1.含有双宾语的主动句变为被动句时，通常把指“人”的间接宾语变为主语，指“物”的直接宾语保留不变；如果把指“物”的直接宾语变为主语，则在间接语前加to或for。例如：He sent me a photo of lucky.变为被动语态：I was sent a photo of lucky. A photo of lucky was sent to me.2.主动句中感官动词see / hear / watch / feel等和

12、使役动词make / let / have等后跟省略to的动词不定式，变为被动语态时应加上不定式符号to。Our teacher made us stand there.改为被动语态We were made to stand there by our teacher.3.系动词、不及物动词或某些短语动词（happen, take place, come true, fall asleep）没有被动语态。例如：What happened to Mr. Brown? 布朗先生发生了什么事？4a Rewrite the sentences using the passive voice.1.
