被动语态(单元重点,必考易错点)1. 定义被动语态(Passive Voice)是英语中一种特殊的句子结构,用来强调动作的承受者而不是动作的执行者。什么时候用被动语态呢?当我们更关心'什么东西被做了',而不是'谁做了这件事'的时候。举个例子,'电话被贝尔发明了'——你更想强调的是电话这个发明,而不是贝尔这个人,这时候就该用被动语态。2. 详细用法(1)基本结构★ be动词 + 及物动词的过去分词(+ by 动作执行者)被动语态的核心结构很简单:be动词加上过去分词。by后面跟的是动作的执行者,也就是'谁做了这件事',但by短语可以省略——因为用被动语态本来就是为了弱化执行者嘛。要注意,be动词会随着时态和主语变化,但过去分词始终不变。(2)三种时态的被动语态★ 一般现在时被动语态:am/is/are + done当我们要描述一个现在的客观事实或经常性的动作时,用一般现在时的被动语态。比如,'纸被用于书写和印刷',这是一个一般性的陈述,所以用is used。常用场景:描述发明的用途、客观事实A mini-camera _______________ to the front of the glasses.(一个微型相机连接在眼镜前面。)The oil and salt ____ also _____ by the machine itself.(油和盐也是由机器自动添加的。)Paper is used for writing and printing.(纸被用于书写和印刷。)★ 一般过去时被动语态:was/were + done当我们讲述过去发生的事情,特别是描述历史发明的过程时,用一般过去时的被动语态。本单元造纸术的整个制作过程,全部都用的是was/were + done。为什么?因为蔡伦造纸是过去的事,而且我们更关注'材料被怎么处理',而不是'谁处理的'——所以被动语态在这里是最自然的选择。常用场景:描述历史发明、过去的事件A radio message _______________ across the Atlantic Ocean in 1901.(1901年,无线电报首次被发送跨越大西洋。)The telephone _______________ by Alexander Bell in 1876.(电话是亚历山大·贝尔在1876年发明的。)All the ingredients _______________ and _______________ in water.(所有原料被混合并在水中煮沸。)★ 含情态动词的被动语态:can/must/should + be + done情态动词后面跟被动语态的时候,结构是'情态动词 + be + 过去分词'。这里有一个特别容易出错的地方——很多同学会忘记be,直接写can made。记住:情态动词后面一定要加be,然后再加过去分词!因为can后面必须接动词原形,而被动语态的'原形'就是be done。常用场景:描述可能性、必要性、建议Toys, chairs, tables, and even houses ___ all _______________ by the 3D printer.(玩具、椅子、桌子,甚至房子都可以由3D打印机制造。)More astronauts will _______________ to the space station.(更多的宇航员将被送往空间站。)The invention _______________ easy to operate.(这项发明应该易于操作。)3. 主动语态 → 被动语态转换这是考试中最常考的题型之一。转换的时候,牢记四步走:① 找宾语:找出主动句中的__________,它就是被动句的___________。② 宾语变主语:把宾语放到__________,变成被动句的____________。③ 动词变被动:把主动动词变成'_______________',注意时态要保持一致!原来是一般过去时,被动句也要用_______________。④ 主语变by短语:原来的主语放到_____后面,如果不需要强调执行者,by短语可以省略。示例:Alexander Bell invented the telephone in 1876.→ ① 找宾语:the telephone ② 宾语变主语 ③ 动词变被动:was invented ④ 主语变by短语:by Alexander Bell→ The telephone _______________ by Alexander Bell in 1876.(电话是亚历山大·贝尔在1876年发明的。)4. 被动语态的使用场景那么,什么时候该用被动语态呢?主要有以下四种情况:① 不知道执行者:我们不知道是谁做的。比如'The old buildings were destroyed in the earthquake.'——我们知道楼塌了,但不需要说是谁弄的,因为地震本身就是原因。② 不需要说明执行者:执行者是谁并不重要。比如'Paper is used for writing.'——大家都知道纸是用来写字的,没必要强调是谁在用。③ 强调承受者:我们想突出的是动作的承受者。比如'The telephone was invented in 1876.'——这里我们强调的是电话这个发明,而不是发明家。④ 科技/新闻报道:正式文体中常用被动语态,显得更客观。比如'New technology will soon be developed.'——新闻报道往往用被动语态来保持客观的语气。5. 易错点总结(必记)(易错点1):情态动词后漏掉be,直接写过去分词。 Toys can made by the 3D printer. ______________________________(易错点2):be动词与主语不一致,忘记主语是单数还是复数。 The oil and salt is added by the machine. ______________________________(易错点3):过去分词写错,不规则动词的过去分词没有记住。 The material was beated and cut up. ______________________________(易错点4):不及物动词误用被动语态。 The accident was happened in 1903. ______________________________(易错点5):be made of / be made from / be made in 混淆。The desk is _________ wood.(可见原材料——你能看到木头)Paper is _________ wood.(不可见原材料——木头经过化学变化变成了纸)This phone is _________ China.(产地——在中国制造)记忆口诀:of看得出,from看不出,in看产地。6. 语法练习A. 单项选择1.

Voice)是英语中一种特殊的句子结构,用来强调动作的承受者而不是动作的执行者。什么时候用被动语态呢?当我们更关心'什么东西被做了',而不是'谁做了这件事'的时候。举个例子,'电话被贝尔发明了'——你更想强调的是电话这个发明,而不是贝尔这个人,这时候就该用被动语态。2. 详细用法(1)基本结构★ be动词 + 及物动词的过去分词(+ by 动作执行者)被动语态的核心结构很简单:be动词加上过去分词。by后面跟的是动作的执行者,也就是'谁做了这件事',但by短语可以省略——因为用被动语态本来就是为了弱化执行者嘛。要注意,be动词会随着时态和主语变化,但过去分词始终不变。(2)三种时态的被动语态★ 一般现在时被动语态:am/is/are + done当我们要描述一个现在的客观事实或经常性的动作时,用一般现在时的被动语态。比如,'纸被用于书写和印刷',这是一个一般性的陈述,所以用is used。常用场景:描述发明的用途、客观事实A mini-camera is connected to the front of the glasses.(一个微型相机连接在眼镜前面。)The oil and salt are also added by the machine itself.(油和盐也是由机器自动添加的。)Paper is used for writing and printing.(纸被用于书写和印刷。)★ 一般过去时被动语态:was/were + done当我们讲述过去发生的事情,特别是描述历史发明的过程时,用一般过去时的被动语态。本单元造纸术的整个制作过程,全部都用的是was/were + done。为什么?因为蔡伦造纸是过去的事,而且我们更关注'材料被怎么处理',而不是'谁处理的'——所以被动语态在这里是最自然的选择。常用场景:描述历史发明、过去的事件A radio message was sent across the Atlantic Ocean in 1901.(1901年,无线电报首次被发送跨越大西洋。)The telephone was invented by Alexander Bell in 1876.(电话是亚历山大·贝尔在1876年发明的。)All the ingredients were mixed and boiled in water.(所有原料被混合并在水中煮沸。)★ 含情态动词的被动语态:can/must/should + be + done情态动词后面跟被动语态的时候,结构是'情态动词 + be + 过去分词'。这里有一个特别容易出错的地方——很多同学会忘记be,直接写can made。记住:情态动词后面一定要加be,然后再加过去分词!因为can后面必须接动词原形,而被动语态的'原形'就是be done。常用场景:描述可能性、必要性、建议Toys, chairs, tables, and even houses can all be made by the 3D printer.(玩具、椅子、桌子,甚至房子都可以由3D打印机制造。)More astronauts will be sent to the space station.(更多的宇航员将被送往空间站。)The invention should be easy to operate.(这项发明应该易于操作。)3. 主动语态 → 被动语态转换这是考试中最常考的题型之一。转换的时候,牢记四步走:① 找宾语:找出主动句中的宾语,它就是被动句的新主语。② 宾语变主语:把宾语放到句首,变成被动句的主语。③ 动词变被动:把主动动词变成'be + 过去分词',注意时态要保持一致!原来是一般过去时,被动句也要用was/were。④ 主语变by短语:原来的主语放到by后面,如果不需要强调执行者,by短语可以省略。示例:Alexander Bell invented the telephone in 1876.→ ① 找宾语:the telephone ② 宾语变主语 ③ 动词变被动:was invented ④ 主语变by短语:by Alexander Bell→ The telephone was invented by Alexander Bell in 1876.(电话是亚历山大·贝尔在1876年发明的。)4. 被动语态的使用场景那么,什么时候该用被动语态呢?主要有以下四种情况:① 不知道执行者:我们不知道是谁做的。比如'The old buildings were destroyed in the earthquake.'——我们知道楼塌了,但不需要说是谁弄的,因为地震本身就是原因。② 不需要说明执行者:执行者是谁并不重要。比如'Paper is used for writing.'——大家都知道纸是用来写字的,没必要强调是谁在用。③ 强调承受者:我们想突出的是动作的承受者。比如'The telephone was invented in 1876.'——这里我们强调的是电话这个发明,而不是发明家。④ 科技/新闻报道:正式文体中常用被动语态,显得更客观。比如'New technology will soon be developed.'——新闻报道往往用被动语态来保持客观的语气。5. 易错点总结(必记)(易错点1):情态动词后漏掉be,直接写过去分词。 Toys can made by the 3D printer. Toys can be made by the 3D printer.解析:can后面必须接动词原形,被动语态的'原形结构'就是be done,所以can后面要有be。(易错点2):be动词与主语不一致,忘记主语是单数还是复数。 The oil and salt is added by the machine. The oil and salt are added by the machine.解析:The oil and salt是两个东西,是复数,所以be动词要用are。做被动语态题时,第一步永远是先看主语是单数还是复数!(易错点3):过去分词写错,不规则动词的过去分词没有记住。 The material was beated and cut up. The material was beaten and cut up.解析:beat的过去分词是beaten,不是beated!不规则动词的过去分词必须单独记忆,不能简单加-ed。本单元需要特别注意的不规则过去分词:beat→beaten, spread→spread, cut→cut。(易错点4):不及物动词误用被动语态。 The accident was happened in 1903. The accident happened in 1903.解析:happen是不及物动词,没有被动语态!常见的不及物动词还有take place(发生)、appear(出现)、disappear(消失)等。判断方法很简单:不及物动词后面不能直接接宾语,所以不可能有被动语态。(易错点5):be made of / be made from / be made in 混淆。The desk is made of wood.(可见原材料——你能看到木头)Paper is made from wood.(不可见原材料——木头经过化学变化变成了纸)This phone is made in China.(产地——在中国制造)记忆口诀:of看得出,from看不出,in看产地。6. 语法练习A. 单项选择1.
