第7章动词的过去分词形式 动词的-ed形式也是非谓语动词的一种,它具有动词的一些特点,同时也具有形容词、副词的句法功能,在句中可用作表语、定语、状语和宾语补足语等。 一、动词的-ed形式的特征 A.动词的-ed形式是由动词的过去分词构成 动词的-ed形式只有一种形式,即传统语法中的过去分词。绝大部分的动词的-ed形式由动词原形加-ed构成,也有一些动词的-ed形式是不规则的。 1.规则动词的-ed形式 limit→limited(限制) pretend→pretended(假装) escape→escaped(逃脱) provide→provided(提供) refer→referred(提交) drag→dragged(拖) pray→prayed(祈祷) supply→supplied(供应) 2.不规则动词的-ed形式 cast→cast(投掷) spread→spread(传播) bite→bitten(咬) forgive→forgiven(原谅) spit→spat(吐) wear→worn(穿) fight→fought(搏斗) lose→lost(丢失) 3.少数动词的-ed形式作定语时,读音与一般过去分词不同 learned a learned professor 一位知识渊博的教授 aged an aged man 老人 beloved his beloved computer 他心爱的计算机 B.动词的-ed形式的否定形式 动词的-ed形式的否定形式是由not或never加动词的-ed形式构成。 Not allowed to go in, he had to wait outside. 不允许他进去,他只好在外面等着。 Never invited to his party, she got angry with him. 从未被邀请过去他的聚会,她很生气。 C.动词的-ed形式的特征 动词的-ed形式有被动的意思,有时也可表示完成的动作。 1.动词的-ed形式表示已完成的动作。 除了作形容词用的-ed形式外,动词的-ed形式可带有完成的意义,有的同时也带有被动的意义。

英语语法归纳之非谓语动词(动名词) 敬告: 以下内容,不参加高考等有语法题(语法单选、语法填空、短文改错等)考试的应用类学员无须深究,知道该语法结构的存在,及其充当的句子成分和功能即可,应多花时间练习听说读写,否则就背离了语言学习真正目的。应试类学员有时间可以比较分析,基本搞懂。 过去分词长什么样?规则的情况下与动词过去式相同,当然有不规则的情况;过去分词可以充当定语、状语、补语、定语,不可能充当主语、宾语; 过去分词不像现在分词有多种体现时态和语态的形式,只有一种形式done表示。 1、过去分词可以充当主谓宾补句型中的宾语补语;它与宾语是被动关系,或者说它与宾语是动宾关系。 (1) We found the fish eaten by our cat. (2) I can’t make myself understood because of my poor English. 2、过去分词可以充当定语;充当定语当然是修饰主语、宾语等名性的结构;表达过去分词的动作是被动的或完成,或即被动又完成的。 (1) The party had last night (which was had last night) was very cheerful. (2) USA is a developed country (a country which has been developed). (3) A great number of students questioned (who had been questioned) said they were forced to practice the piano. 3、过分词可以充当状语,它与主句主语是被动关系,或者说它与主句的主语是动宾关系; 过去分词一般只强调被动动作而不强调时间,多用于条件和原因状语;(1) Taken in time, the medicine will turn out to be very effective. If the medicine is taken in time, it will turn out to be very effective. (2) Offered an important role in a new movie, Andy has a chance to become famous.

过去分词教案 一.教学目的 1.要求学生理解过去分词 2.基本掌握二.教学难点过去分词的用法三.教学过程 1.过去分词作定语 (1)过去分词用作定语,总的来说,充当前置修饰语的过去分词通常来自及物动词,带有被动意义和完成意义,如: a broken cup 一只打破的杯子(被动)the risen sun 已升起的太阳(完成)the fallen leaves 落叶(在地上)spoken English 口语 (2)有些过去分词不能单独作前置修饰语,但可以借助某些前缀或副词来作前置定语。例如:uninvited guests 没有被邀请的客人 unheard- of stories没有听说过的故事 an unexpected happening 意想不到的事 badly-built house 建得很差的房子newly-born baby 新出生的婴儿 highly-developed industry 高速发展的工业 (3)一般来说,不及物动词的过去分词很少单独作前置修饰语,能这样用的仅限于少数几个词,他们作前置定语时仅指完成意义,而不指被动。如: a retired worker (a worker who has retired )一个退休工人 an escaped prisoner (a prisoner who has escaped)一个逃犯 fallen leaves (leaves that have fallen)落叶 the risen sun (the sun that has just risen)升起了的太阳 a returned student (a student who has returned)回归的学生 a grown man (a person who has grown to a man's size )一个成年人 (4)某些不及物动词的过去分词,单独不可以作前置定语,但可以与某些副词构成复合形容词作前置定语,如: well-behaved children 表现好的孩子 a widely-travelled business man 游历广泛的商人newly-arrived visitors 刚来的参观者

He is a leader________ (respect) by the people. 3 及物动词的过去分词(done)与现在分词的被动式 (being done)都可以表示“被动”,但前者多表示一个 完成了的动作,而后者则表示一个正在进行的动作. the problem discussed yesterday The problem being discussed 1. We lived in the house __built by my uncles ________________ (我舅舅们修建的). 2. Any medicine ___taken_____(服用) without the advice of a doctor can cause trouble. 3.

不定式、动名词、过去分词 作定语的用法

不定式作定语的用法 不定式及其短语作定语,与其他短语作定语一样,一般都放在被修饰的词之后,通常表示一个将来的动作,有时也可以表示某一过去的特定动作。 一些名词后常用不定式作定语,如:chance(机会),way(方法),time(时间)等;另外,the first,the second,the last,the only等作名词或者它们作形容词用来修饰代词,它们或它们所修饰的代词后,也常用不定式作定语。 不定式作定语时,不定式与被修饰词之间存在的关系复杂,有的是主谓关系;有的是动宾关系;有的是动状关系,还有的不存在主谓、动宾、动状关系。 1、主谓关系的 (1)We must find a person to do the work. (2) There is no one to take care of her. (3) In my family, my mother is always the first one to get up. (4) He is always the first to come and the last to leave. (5) We need someone to go and get a doctor. 2、动宾关系的 如果不定式与被修饰的词在逻辑上存在动宾关系,不定式里的动词必须是及物动词。注意:是及物动词的,后面不要再加宾语,因为前面的被修饰词是它的宾语;是不及物动词的,要加上适当的介词或副词让它变成及物动词,只有这样,它才能带上前面的宾语。 (1) He has a lot of books to read. (2) I would like a magazine to look at. (3) Here is some advice for you to follow. (4) Do you have anything else to say? (5) There is no one to take care of. (6) She has nothing to worry about.

过去分词作定语用法.

过去分词作定语用法 (Past Participles Used as Attributes) 过去分词作定语,在语态上,表被动;在时间上,表示动作已经发生或完成,与它所修饰的名词有逻辑(意义)上的动宾关系。过去分词作定语时,所修饰的名词在逻辑上相当于被动句中的主语,过去分词相当于谓语。 过去分词作定语表示动作在谓语动作之前发生,已经完成并具有被动意义。有时也不表示时间性。作定语的过去分词一般由及物动词变来,因为只有及物动词才有被动意义。例如:He is a teacher loved by his students. 他是个很受学生爱戴的老师。 也有用不及物动词的过去分词作定语的情况,一般作前置定语,它不表示被动意义,只表示主动意义,强调动作完成。不能像及物动词的过去分词那样放在名词后面作定语。例如:fallen leaves 落叶 retired workers 退休工人 the risen sun 升起的太阳 注意下面过去分词作定语的几种情况: 1. 单个的过去分词作定语一般放在被修饰的名词之前。例如: We needed much more qualified workers. 我们需要更多的合格的工人。 My friend is a returned student. 我的朋友是个归国的留学生。 单个分词也可以作后置定语,用以强调动作。例如: They decided to change the material used. 他们决定更换使用的材料。 2. 过去分词短语作定语要放在被修饰的名词后面,作后置定语,其作用相当于一个定语从句。例如: The student dressed in white is my daughter. =The student who is dressed in white is my daughter.)穿白色衣服的学生是我的女儿。 3. 如果被修饰的词是由every/some/any/no + thing/body/one所构成的复合代词或指示代词those等时,即使一个单一的分词作形容词用,也要放在被修饰词的后面。例如: Is there anything unsolved? 还有没解决的问题吗? There is noting changed here since I left this town.自从我离开这个城镇以来,几乎没有什么变化。 4. 单个过去分词前加一名词或副词,常用连字符将它们连接起来构成一个复合形容词,放在其修饰的名词前,作前置定语。分词前加的名词表示分词的动作或行为主体,所加的副词表示方式、时间、程度、性质等意义。例如: This is a state-owned factory. 这是一家国营工厂。 This is our school-run factory. 这是我们的校办工厂。 5. 作前置定语的某些动词的过去分词的形式与作谓语或表语的过去分词的形式往往不一样。例如: 原形用作定语的过去分词用作表语或谓语的过去分词 drink drunken drunk

get+过去分词用法详解

“be +过去分词”能构成被动结构,其实在现代英语口语或非正式文体中还常用另一种被动结构“get + 过去分词”。和“be + 过去分词”一样,“get + 过去分词”也能用于被动结构和系表结构,用于被动结构时,它强调动作的发生;用于系表结构时,它强调状态的变化。其用法及两者的区别从以下两个方面分述如下: 一、get被用来代替助动词be和过去分词连用,构成被动结构,表示某一事件或事故的发生,着重强调动作。 1.常见于以下两种情况: ①谈论某人或某物的客观遭遇,往往表示一种突然的、未曾料到的偶发事件或事故,如:Some glasses got broken when we were moving. 我们搬家的时候有些玻璃杯被打碎了。He got killed when he was crossing the road. 过马路时他被车撞死了。 ②谈论设法做到自己称心的事。当主语是人时,常可在get和过去分词之间插入一个反身代词,表示主语对动作的结果负有一定的责任,此时既含有被动意义,同时又含有主动意义,如: Our car gets cleaned about once every two months. 我们的车每两个月大约清洗一次。She got (herself) paid before she went on a holiday. 她在休假前(设法)领到了工资。 2.“get + 过去分词”与“be + 过去分词”在构成被动结构时的区别: ①前者多用于口语和非正式文体,而后者则可用于更多的场合。 ②前者侧重表示动作,而后者既可表动作又可表状态,有时有歧义,如: The chair got broken yesterday. 昨天这把椅子被弄坏了。(表动作) The chair was broken yesterday. 昨天这把椅子被弄坏了。(表动作)或??昨天这把椅子是坏的。(表状态) ③前者偶尔带表示动作执行者的by短语,而后者则有时带有时不带,如: My brother got hit by a stone. 我哥哥被一块石头击中了。 She got caught by the police. 她让警察给抓住了。 ④前者在表示强调,否定和疑问时需借助助动词do/does/did,而后者则不需,如: He didn’t get beaten yesterday evening. 他昨天晚上没挨打。 Did your letter get answered ? 你收到回信了吗? ⑤前者有时既可表示被动意义,又可表示主动意义;后者则只表示单纯的被动意义,如: I got (myself) invited to lots of parties last holidays. 上次休假期间,我(设法)让人邀请参加了许多社交聚会。 I was invited to lots of parties last holidays. 上次休假期间,我应邀参加了许多社交聚会。 ⑥与助动词be相比,和get连用的过去分词仅限于少数,其中多数含有“不顺利;不愉快”之意,如: He got taught a lesson. 他被教训了一顿。 I got rained on as I was coming to work. 我来上班时遭到淋雨。 二、get作始动性连系动词,与多数都已形容词化了的过去分词连用,构成系表结构,表示状 的变化(即动作的结果),其中get表示一种状态向另一种状态过渡、变化的动作,其含义等于become; begin to be或come to be,如 1.常见于以下五种情况: ①表示使自己进入或变为某种状态,如: We don’t want any of you to get lost. 我们不想你们当中任何人迷路。

过去分词作定语

过去分词作定语,状语以及表语用法 过去分词是非谓语动词的一种形式,表示完成和被动的动作。它在句子中可以充当状语、定语等成分。过去分词与现在分词作状语 过去分词表完成、被动, 与主句主语之间是被动关系; 现在分词表进行, 主动, 与主句主语之间是主动关系。 如果一个被动的动作发生在谓语动词之前, 则可使用现在分词的完成被动式或过去分词。 过去分词表完成、被动, 作状语时, 其逻辑主语是主句的主语, 且与主语之间存在着被动关系。过去分词作状语可表时间, 原因, 让步, 结果, 方式, 条件等。 观察下列的句子: Once published, his works (=Once his works was published, ) became famous for the absence of rhyme at the end of each line. PP作时间状语, 相当于一个时间状语从句有时过去分词前可加连词when或while来强调时间概念。过去分词作时间状语 相当于时间状语从句,有时为了突出时间,可在分词前加when或while。 1. When it is heated, ice will be changed into water. When heated, ice will be changed into water. 2. When it is seen under a microscope, a fresh snowflake has a delicate six-pointed. Seen under a microscope, a fresh snowflake has a delicate six-pointed shape. 过去分词作原因状语 相当于表示原因的状语从句。 1. Since/ As she was given advice by the famous detective, the young lady was no longer afraid. Given advice by the famous detective, the young lady was no longer afraid. 2. Because it was done in a hurry, his homework was full of mistakes. Done in a hurry, his homework was full of mistakes. 过去分词作条件或者假设状语 前面可带if,unless等从属连词,相当于条件状语从句。 1.If they had been given more attention, the cabbages could have grown better. Given more attention, the cabbages could have grown better. 2. If I am compared with you, we still have a long way to go. Compared with you, we still have a long way to go. 作方式或伴随情况状语 没有相当的状语从句可以代替。 1.The hunter left his house, followed by his dog. The hunter left his house, and he was followed by his dog. 2. She sat by the window, lost in thought. She sat by the window, and she was lost in thought. lost 表示一种迷失心理状态 Summary 1) 过去分词在句子中可以作时间状语、原因状语、伴随状语、条件状语和让步状语等。 2) 过去分词作状语时,过去分词的逻辑主语与句子主语一致。 过去分词作状语:过去分词有两大特点: 1. 表示被动的动作; 2. 表示已经完成的动作, 因此, 当过去分词作状语的时候一定要搞清楚分词与主语的逻辑关系--

过去分词用法详解

过去分词的用法 一、构成:规则动词的过去分词是有动词原形+ed构成的,不规则动词则有各自构成。 二、基本特点:过去分词在句子中的基本用法有两点:1.与逻辑主语之间是被动关系 2.表示完成的动作 三、过去分词的用法: 1.作表语:过去分词作表语时,一般同时具备被动与完成的含义 例如:(1)The cup is broken.(2)He is retired. (3)After running,he is tired. 【注意】过去分词作表语时,已经变成形容词性质,主要表示主语的状态(被动完成),而被动语态则表示动作. 例如:(1) The cup was broken by my little sister yesterday. 茶杯是昨天我小妹打碎的.(是被动语态,表示动作) (2)The cup is now broken. 茶杯碎了.(过去分词作表语,表示状态) 【注意】有些动词如interest, bore, worry, surprise, frighten 等通常用其过去分词形式来修饰人,表示“感到……” 用-ing 形式来修饰物,表示“令人……” 例如:The book is interesting and I'm interested in it. 这本书很有趣,我对它很感兴趣. 2.做定语 作定语用的过去分词其逻辑主语就是它所修饰的名词.及物动词的过去分词作定语,既表被动又表完成;不及物动词的过去分词作定语,只表完成. 1)单一过去分词作定语,常置于其所修饰的名词之前,称作前置定语。 例如:We must adapt our thinking to the changed conditions. 我们必须使我们的思想适应改变了的情况. 2)过去分词短语用作定语时,一般置于其所修饰的名词之后,相当于一个定语从句,称作后置定语。 例如:The concert given by their friends was a success.他们朋友举行的音乐会大为成功. 3)过去分词短语有时也可用作非限制性定语,前后常有逗号. 例如:The meeting, attended by over five thousand people, welcomed the great hero. 4)用来修饰人的过去分词有时可以修饰与人有关的表情,面貌,举止行为以及感觉等,这时不能用v-ing形式例如:The boy looked up with a pleased expression. His satisfied look showed that he had passed this exam. 3.作状语 作状语的过去分词在句子中多表示被动和完成两重含义。 1)时间状语:A.当和谓语动词动作同时发生时,一般仅表示被动,可以用when从句代替。 例如:Faced with difficulties,we shouldn’t withdraw for any excuse. B.当表示动作发生在谓语动词之前时,通常既表被动又表完成,可用after从句代替,也可用现在分词的被动完成形式代替。 例如:Caught by the police,the thief lay on the ground,crying and shouting. 2)原因状语:过去分词所表示的动作多有被动和完成两重含义。 例如:Written in a hurry, this article was not so good! 因为写得匆忙,这篇文章不是很好. Welcomed by all the students,we expressed own true thanks to them.被全体同学欢迎,我们表达真挚的感激【注意】有些过去分词因来源于系表结构,作状语时不表被动而表主动.这样的过去分词及短语常见的有: lost (迷路); seated (坐); hidden (躲); stationed (驻扎); lost / absorbed in (沉溺于); born (出身于); dressed in (穿着); tired of (厌烦). 等,这种结构可以改写成一个because引导的主系表结构句子。 例如:Lost / Absorbed in deep thought, he didn't hear the sound.因为沉溺于思考之中,所以他没听到那个声音. Tired of the noise,he decided to move to the country.因厌倦了噪音,他决定搬到农村去。 Dressed in an orange dress,she looked more beautiful than before.穿上橘红色连衣裙,她看起来比以前更美3)条件状语:作条件状语时,一般只表被动含义。相当于if引导的条件状语从句。 例如:Grown in rich soil, these seeds can grow fast. 如果种在肥沃的土壤里,这些种子能长得很快. 4)伴随情况:表示伴随谓语动词发生的另外动作,位于主语之后,用逗号隔开,可以同时表示被动与完成, 例如:The mother ran across the street,followed by her little son. 5)结果状语:表示发生在谓语动词后的动作,位于主句后用都逗号分开,也可以同时表示被动与完成。 例如:He listened to the hero’s story,moved to tears. 【注意】状语从句改成过去分词作状语时有时还可保留连词,构成"连词+过去分词"结构作状语. 例如:When given a medical examination, you should keep calm. 当你做体格检查时要保持镇定.
