过去分词作定语和状语

概念引入 在前两个单元我们已经学过过去分词作定语和表语,及过去分词作宾语补足语,在本单元中我们先复习一下过去分词作定语,然后学习过去分词作状语。 看下面句子: 1. Worried about the journey, I was unsettled for the first few days. 2. Well-known for their expertise, his parents’ company, called “Future Tours”, transported me safely into the future in a time capsule. 3. Hit by a lack of fresh air, my head ached. 4. Exhausted, I slid into bed and fell fast asleep. 5. Described as an enormous round plate, it spins slowly in space to imitate the pull of the earth’s gravity. 这些句子中斜体词部分都是过去分词,在句中作状语。那么过去分词作状语,有什么需要注意呢? ?过去分词作定语 ?过去分词作状语----入门篇 ?过去分词作状语----用法小结篇 ?分词作状语的区别 ?作插入语的分词 用法讲解 过去分词作定语 在第一单元,我们已经学过了过去分词作定语的用法,这里做一简单复习。 1. 过去分词作定语与定语从句: 过去分词作定语,具有形容词或副词的作用,该分词及其修饰成分相当于定语从句。如果把分词短语转变成定语从句时,这个定语从句应具备两个特征: 1)从句的主语和所修饰的先行词一致;如2)的例句1中定语从句的主语就是所修饰词a teacher。 2)从句的谓语动词为被动语态形式。

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

现在分词做定语及状语

现在分词(V-ing)作定语和状语 课前预习案 学习建议:根据所列例句,理解并尝试总结现在分词在句子中的用法。 动词--ing形式作定语和状语 I.ing 形式作定语 1. 现在分词作前置定语时,在逻辑上与所修饰的名词之间为主谓关系,也可改成定语从句;如果与所修饰的名词之间没有主谓关系,定语相当于一个介词for 引导的短语。现在分词位于所修饰的名词之后做后置定语,与所修饰的名词之间呈逻辑上的主谓关系,相当于一个定语从句。如:a listening child= a child who is listening, a walking stick= a stick for walking. 2. 现在分词作定语往往表示“令人……”,主动的或正在进行的动作。如:a moving film, a developing country. II. ing 形式作状语 动词-ing形式在句子中做状语,表示的动作是主语动作的一部分,与谓语动词表示的动作或状态是同时或者几乎同时发生的,经常可以做时间、原因、方式、条件、结果、目的、让步状语从句。句子的主语必须是状语的逻辑主语;而且主语与作状语的分词之间呈逻辑上的主谓关系。 1.原因状语,相当于原因状语从句。 1).Being ill, she didn’t go to school today. 因为生病,她今天没上学去。 2). Seeing no one at home, I decided to come again. 看见没有人在家,我决定再来一趟。 2. 时间状语,相当于when, while等引导的从句。 1).Hearing the good news, he jumped with joy. 当听到这个好消息时,他高兴地跳了起来。 2).Walking in the street, I saw a friend of mine.

高考英语语法详解:现在分词作状语和过去分词作状语的区别

高考英语语法详解:现在分词作状语和过去分词作状语的区别 非谓语动词主要包括不定式、动名词和现在分词。为了区分这三种不同的非谓语动词的用法和含义,我们将分别从三种非谓语动词在句子中做主语、宾语、宾语补足语、定语、状语、表语以及一些特殊结构句型等角度来区分其用法和细微含义。 1.不定式和动名词作主语的区别 (1)动名词作主语通常表示抽象动作;而不定式作主语表示具体动作。 Smoking is prohibited(禁止)here.这里禁止抽烟。(抽象) It is not very good for you to smoke so much.你抽这么多烟对你身体很不好。(具体) (2)动名词作主语时,通常用以表示一件已知的事或经验。 不定式短语通常用来表示一件未完成的事或目的。 Climbing mountains is interesting.爬山很有趣。(经验) Driving a car during the rush hour is tiring.在高峰时刻开车令人厌烦。(经验) (3)不定式做主语,一般用it当形式主语,把作主语的不定式短语后置。 It took me only five minutes to finish the job. 2.不定式、动名词和分词作表语的区别 (1)不定式作表语 1)不定式作表语一般表示具体动作,特别是表示将来的动作。 To do two things at a time is to do neither.--次做两件事等于未做。 What I would suggest is to start work at once.我的建议是立刻开始干。 2)如果主语是不定式(表示条件),表语也是不定式(表示结果)。 To see is to believe.百闻不如一见。 To work means to earn a living.工作就是为了生活。 3)如果主语是以aim,duty,hope,idea,happiness,job,plan,problem,purpose,thing,wish等为中心的名词,或以what引导的名词性从句,不定式作表语是对主语起补充说明作用。 His wish is to buy a luxurious car in the near future.他的希望是在不远的将来买一辆豪华轿车。 The function of Louis Sullivan's architecture was to provide large uninterrupted floor areas and to allow ample light into the interior. The most important thing is to negotiate with them about the future of the plant. (2)动名词作表语:动名词作表语,表示抽象的一般性的行为。 Our work is serving the people.我们的工作是为人民服务。 His hobby is collecting stamps.他的爱好是集邮。 (注)动名词作表语时与进行时态中的现在分词形式相同,但其所属结构迥异,进行时态说明动作是由主语完成的。动名词做表语,说明主语的性质或情况。 People cannot but feel puzzled,for they simply cannot understand how he could have made such a stupid mistake. His victory in the final was no more convincing than I had expected.

过去分词作状语

过去分词作状语 【观察】观察下列句子中过去分词的用法,然后加以总结。 1. Discussed many times, the problems were settled at last. 2. Looked at from a distance, the painting seems much more beautiful. 3. Caught in the rain on my way home, I had a bad cold. 4. Built thirty years ago the house still looks very beautiful. 5. The professor, followed by his assistants, walked out of the hall. 6. She sat by the window alone, lost in thought. 7. Satisfied with what he did, the teacher praised him in class. 8. Water can be changed into vapor when heated. 9. There is no point arguing about it; just do as told. 10. He rushed into the room, his face covered with sweat. [总结] 过去分词可作定语、状语、表语和宾语补足语。过去分词作状语应注意以下几点: 一、过去分词作状语表示的意义 ●表示时间(如例句1)、条件(如例句2)、原因(如例句3)、让步(如例句4) 的分词短语相当于相对应的状语从句。 After they had been discussed many times, the problems were settled at last. If it is looked at from a distance, the painting seems much more beautiful. Because I was caught in the rain on my way home, I had a bad cold. Although it was built thirty years ago, the house still looks very beautiful. ●作方式状语或表示伴随情况,说明动作发生的背景或情况。一般情况下,分词所表示的动作和谓语动词所表示的动作同时发生。可转化成并列句。(如例句5-6) The professor walked out of the hall and he was followed by his assistants. She sat by the window alone, and she was lost in thought. 二、过去分词与句子主语之间的关系 ●过去分词作状语表示被动或完成的动作。其逻辑主语一般应与句子的主语一致。过去分词与句子主语之间通常存在逻辑上的动宾关系。(如例句1-5) 【难点点拨】分词作状语时,用现在分词还是过去分词,取决于分词与句子主语之间的关系。主动关系用现在分词,被动关系用过去分词。比较: Seeing from the top floor, we can find the garden more beautiful. Seen from the top floor, the garden looks more beautiful. ●有些过去分词或短语来源于系表结构,或某些动词后面加-ed转化来的形容词,作状语时不表被动而表主语的状态。常见的有lost(如例句6), seated, hidden, lost in, dressed in, faced with, absorbed in, surprised, disappointed, exhausted, frightened, satisfied(如例句7), tired等。 三、“连词+过去分词”结构作状语 过去分词作状语时,可在分词之前加某些连词,以表示强调。常用的有if, unless, when(如例句8), once, until, though/ although, even if/ even though, as(如例句9), as if等。 【难点点拨】此结构实际是状语从句的省略形式。当状语从句的主语与主句的主语一致,且状语从句的谓语动词是被动式时,省略从句的主语和动词be即是。 Water can be changed into vapor when (it is) heated. There is no point arguing about it, just do as (you are) told. 四、过去分词的独立主格结构作状语 如果过去分词的逻辑主语与句子的主语不一致,这种带逻辑主语的过去分词结构属于独立主格结构,作状语,表示时间、原因、条件、方式、伴随等(如例句10)。

过去分词做状语和定语时的区别

过去分词做状语和定语时的区别 一、过去分词(短语)做状语 1、与句子主语的关系 当过去分词(短语)做状语时,要与句子的主语有关系,而且一般是被动关系。在读下面所有的例句时,请注意过去分词短语与句子主语的关系。 先分析例句:Frightened by Santa Claus …words,Scrooge woke up. 句子的主语是Scrooge,状语部分为Frightened by Santa Claus?words,可以看出Scrooge是“被”Santa Claus的话“惊吓”(Frightened)。 2、在句子中的位置 过去分词做状语,修饰的是句子中的位于,多放在句首,也可以放在后面,后者插在句子的中间。Seen from the hill,the city looks magnificent.从山上看这座城市非常壮观。 They came in,followed by their wives.他们进来了,妻子们跟随在后。 Tom,horrified at what he had done,could at first say nothing. Tom对他做的事感到恐惧,一时说不出话来。 3、所表示的状语种类 过去分词做状语可以表示伴随情况(即主句的谓语动作与状语同时发生)、表示原因、表示条件、也可以表示时间。 He entered,accompanied by his secretary.(伴随情况)他由秘书陪着走了进来。 Moved by his speech,many people volunteered to help in the work.(原因)由于受他讲话的感动,许多人自愿参加这项活动。 Taken in time,the medicine will be quite effective.(条件)如果及时服用,这种药是相当有效的。Heated,water changes into steam.(时间)当被加热的时候,水可以变成蒸汽。 4、所需注意的问题 1)过去分词有时可以和连词一起使用。(实际上就是我们上一期讲到的状语从句的省略现象) He will come if asked.(if后面省略了heis)若受到邀请,他会来得。 Whenever asked about it,he could hardly hold back his feelings.(Whenever后面省略了hewas) 每当有人问及此事,他就难以控制自己的感情。 2)在分析“与句子主语的关系”的关系时,提到“当过去分词(短语)做状语时,要与句子的主语有关系,而且一般是被动关系。”但是,在语言的发展过程中,有一些过去分词短语在使用的过程中成为了固定结构,当使用这些固定结构时不需要分析它们与主语的关系,就直接使用。常见的有以下几种:judged by…由….判断、断定,provided:conj.(=on the condition that)假如,如果,倘若...,在...条件下,后面常加that引导的从句,that可以省略。 (providing也可以有这种用法,也就是说provided与providing做连词使用,用法及含义是一样的。)given…倘若...[假定...]
