初中英语语法：被动语态.ppt

语态 voice 是个语法范畴 它是一种动词形式 表示动词的主语与该动词所表示的动作之间的主动和被动关系 当主语是动作的执行者时 动词用主动语态 ActiveVoice 如果主语是动作的承受者 动词便用被动语态 PassiveVoice Wecleanedtheclassroomyesterday 昨天我们打扫了教室 Theclassroomwascleanedbyusyesterday 昨天教室被我们打扫了 动词的被动语态由 助动词be 及物动词的过去分词 构成 当主动句变为被动句时 原来的宾语变成了主语 原来的主语变成了介词by的宾语 主动句与被动句的结构虽然不同 但动作的执行者和承受者的关系并没有改变 一般现在时 am is aredone一般过去时 was weredone现在进行时 am is arebeingdone过去进行时 was werebeingdone现在完成时 have hasbeendone过去完成时 hadbeendone一般将来时 shall willbedone begoingtobedone当句中含有情态动词时 句子结构为can must haveto bedone Heisregardedasabrilliant 他被认为很有才气 Thisbookwaswrittenin1969 这本书是1969年写成的 Thebrokenbikeisbeingrepairednow 那辆坏了的自行车正在被修理 Hetoldusthecatwasbeingwashedwhenwecalledhim 他告诉我们打电话时他正在给猫洗澡 Thepenhasbeenusedforseveralyears 这支钢笔已经用了几年 Hesaidthefactoryhadbeenopened 他说这家工厂已经开张 Theworkwillbefinishedinthreehours 工作将于三小时后完成 Thebabymustbelookedafterwell 这孩子必须被好好照顾 在被动句中有时用by 词组 有时不用 一般来说 当动作的执行者为谁不甚清楚 不甚重要或难以说出时 通常不用by 但有时为了强调动作执行者或者由于上下和结构上的需要则必须使用by词组 例如 一 主动句与被动句的转换 1 含有单宾语的主动句的转换 HamletwaswrittenbyShakespeare 哈姆雷特 是莎士比亚写的 PeoplespeakEnglishalmostallovertheworld 世界各地都有人讲英语 当主动句的宾语是that引导的宾语从句 可转换为两种形式的被动句 1 用先行的it作形式主语 把宾语从句变成后置的主语从句 2 把宾语从句里的主语变成被动句的主语 同时把宾语从句中的谓语变成不定式短语 Englishisspokenalmostallovertheworld Peoplebelievethatheisanhonestboy 大家认为他是个诚实的孩子 2 含有双宾语的主动句的转换 IgavethebooktoMr Smithyesterday 昨天我给了史密斯先生一本书 Itisbelievedthatheisanhonestboy
