过去分词构成形式: 1.规则动词:规则动词的过去分词的构成规则与规则动词的过去式的构成规则相同。四点变化规则: (1)、一般动词,在词尾直接加“ ed ”。(然而要注意的是,过去分词并不是过去式) work---worked---worked , visit---visited---visited (2)、以不发音的“ e ” 结尾的动词,只在词尾加“ d ”。 live---lived---lived (3)、以“辅音字母 + y ”结尾的动词,将 "y" 变为 "i" ,再加“ ed ”。 study---studied---studied,cry---cried---cried,try---tried---tried,fry---fried---fried.[1] (4)、重读闭音节结尾,末尾只有一个辅音字母,先双写该辅音字母,再加“ ed ”。 stop---stopped---stopped , drop---dropped--dropped (5)、以ic结尾的动词,要把ic变成ick再加ed, picnic→picnicked ,traffic→trafficked 2 、不规则动词:见不规则动词表
分词用法: 1、分词作状语 分词在句子中作状语,可以表示时间、条件、原因、结果、让步、伴随等。 分词(短语)作状语时,其逻辑主语应与句中主语相一致。 当现在分词表示的动作发 生在谓语动词之前时, 则用现在分词的完成式,且所表示动作与谓语动作同时发生, 则用现在分词的一般式。 完成或被动关系用过去分词。 ①现在分词: The students went out of the classroom, laughing and talking. ②过去分词: Accompanied by his friend, he went to the railway station. Given better attention, the plants could grow better.
2、“while ( when, once, until, if , though等连词)+分词”结构 现在分词或过去分词作状语时,有时可以在分词前加while,when, once, although, until, if等连词。 ①现在分词: When leaving the airport, she waved again and again to us. While waiting for the train, I had a long talk with my sister about her work…… ②过去分词: Once recovered, he threw himself into his work and made every effort to do it well. Although working very hard, he failed to pass the final exam. If translated word by word, the passage will be difficult to understand.
3、分词作定语 分词作定语时,单个的分词通常放在被修饰的名词之前,分词短语一般置于所修饰的中心词后面。 现在分词修饰的是发出该动作的名词(即与名词有主谓关系),过去分词修饰承受该动作的名词(即与名词是动宾关系)。 We will go on with our experiment as soon as we get the added fund. This is really an exhausting day to all of us! We can see the part of the moon lighted by sunlight. After a night spent in excitement and sleeplessness, I forced myself to take a long walk along the beach the next day. More and more developing countries established strategic partnership with developed countries
4、分词作宾语补足语 现在分词在see, watch, hear, observe, notice, feel, find, glimpse, glance等感官动词和look at, listen to等短语动词以及 have, keep, get, catch, leave, set, start, send等使役动词后面与名词或代词构成复合宾语,作宾语补语的成分。 例:I see him passing my house every day. I caught him stealing things in that shop. I smelt something burning.
5、分词作表语 分词作表语通常看作形容词来用。 过去分词表示主语的感受或状态,主语多为人。现在分词表示主语的性质,而且主语多为物; ①过去分词: We were so bored that we couldn’t help yawning. She felt confused, and even frightened. ②现在分词: He was very amusing. That book was rather boring. 很多动词的现在分词都可以作表语: exciting, interesting, encouraging, disappointing, confusing, touching, puzzling.
动名词的结构和形式: 动名词的否定结构: 动名词的否定结构由not 动名词组成。如: Trying without success is better than not trying at all. 实验没有成功也比不实验好。 He hated himself for not having work hard. 他悔恨自己没有用功。 I’m sorry for not having telephoned you before. 很抱歉,没有早给你打电话。 He felt sorry for not having done the work well. 他为没有把工作做好感到难过。 I fancy it has done you a lot of good not going. 我看不去对你倒好了。 (not going 是动名词一般式的否定形式) There is no denying the fact that he si diligent. (no denying 也是动名词一般式的否定)
动名词复合结构: 通常情况下,动名词的逻辑主语为谓语动词的主语。如果动名词动作的发出者不失谓语动的主语时,则需要有自己的逻辑主语物主代词或名词所有格加动名词就构成了动名词的复合结构,这种结构在句中可以作主语,宾语等。 (1)逻辑主语是有生命的名词作主语时,必须用名词或代词所有格,作宾语时(尤其在口语中),也可用名词普通个或人称代词宾格。如: Do you think my going there will be of any help? 你看我去会有什么帮助吗?(宾语) The student’s knowing English well helps him in learning French. 这位学生通晓英语对他学法语很有帮助。(主语) Do you mind my(me) smoking ? 你介意我抽烟吗?(宾语) They insist on Mary’s (Mary) going with them there. 他们坚持要玛丽跟他们一起去那儿。(介词宾语) (2)逻辑主语是无生命名词是,通常只用名词普通格。如: Do you hear the rain pattering on the roof? 你听见雨点打在屋顶上了吗? Is there any hope of our team winning the match ? 我们对赢得比赛有希望吗? (3) 逻辑主语是指示代词或不定代词this that , somebody , someone , nobody, none, anybody, anyone 时,只用普通格。如: She was woken up by somebody shouting outside. 她被外面喊叫的人吵醒了。
动名词的形式(一般式,完成式和被动式): (1) 动名词的一般式所表示的动作与谓语动词所表示的动作同时发生,或在谓语动词表示的动作之后。如: We are very interested in collecting stamps. 我们对集邮很感兴趣。 His coming will be of great help to us . 他来对我们大有帮助。 但是有些明确表示时间的动词和介词 after, on,upon, 或for之后,常用一般式代替完成式,表示动作发生在谓语动作之前。如: I shall never forget seeing the Great Wall for the first time.我永远不会忘记第一次看到长城的情景。 On hearing that bad news , the mother couldn’t help crying. 一听到这个糟糕的消息,母亲就禁不住哭了起来。 Excuse me for coming late. 我来晚了,请原谅。 Thank you for giving us so much help. 谢谢你给了我们这么多帮助。 (2) 动名词的完成式所表示的动作或状态在谓语动词之前完成或结束。 He regrets not having taken part in the work. 他后悔没有参加这项工作。 We were praised for having finished the work ahead of time. 我们因提前完成了这项工作而受到了表扬。 (3)动名词的被动式:当动名词的逻辑主语是行为承受者时,用被动语态。如: I like being given harder work. 我喜欢接受难点的工作。 She is proud of being admitted into the university. 她为被大学录取而感到自豪。 The meeting was put off without his having been consulted. 会议延期并未和他商量。 He doesn’t mind having been criticized. 他不介意过去受到的批评。
动名词与现在分词的关系: 动名词它在形式上与现在分词相同,都是在动词原形的词末加-ing。在现代语法中,这两种形式同视为"-ing形式"。 这两种形式的另一个相同之处是: 它们都是由动词变化而成的,它们都保留了动词的某些特征,它们都能带自己的宾语、状语,而构成动名词短语或是现在分词短语去担当句子成分。 例如: Speaking in the public,he will surely be very cheerful . (现在分词短语,作状语)他在公众场所讲话时总是兴高采烈的。 She hates speaking in the public. (动名词短语,作宾语)她不喜欢在公众场所讲话。
动名词和现在分词都可以用于系动词之后作表语,区别方法是: ①作表语的动名词与主语指的是同一件事,此时系动词相当于“是”,通常把主语和表语的位置互换,语法和意思不变,例如: My hobby is swimming.可改为Swimming is my hobby.(可将原句中的主语与表语位置互换) ②现在分词作表语主要用以说明主语的性质,不能与主语互换位置,例如: The story is interesting .不可改为:Interesting is the story. 2.动名词和现在分词都可以用作定语来修饰名词,两者的区别在于: 动名词修饰名词时主要表示该名词的用途,而现在分词修饰名词时性质、状态或动作等。试比较: ①a swimming boy和a swimming suit 前者的意思是“一个正在游泳的男孩”,即a boy who is swimming,现在分词swimming 表示被修饰名词boy的动作; 而后者的意思是“游泳衣”,即a suit for swimming,动名词swimming表示suit 的用途。 ②a sleeping child 和 a sleeping car 前者的意思是“一个正在睡觉的孩子”,即a child who is sleeping,现在分词sleeping 表示被修饰名词 child 正处于的状态; 而后者的意思是“卧车(被用来睡觉的车厢)”,即 a car which is used for sleeping,动名词 sleeping 表示car 的用途。
动名词的用法: 一、动名词作主语 1. 直接位于句首做主语。例如: Swimming is a good sport in summer. 2. 用 it 作形式主语,把动名词(真实主语)置于句尾作后置主语。 动名词做主语时,不太常用 it 作先行主语,多见于某些形容词及名词之后。例如: It is no use telling him not to worry. 常见的能用于这种结构的形容词还有:better,wonderful,enjoyable,interesting,foolish,difficult,useless,senseless,worthwhile,等。 注意:important,essential,necessary 等形容词不能用于上述结构。 3. 用于“There be”结构中。例如: There is no saying when he'll come.很难说他何时回来。 4. 用于布告形式的省略结构中。例如: No smoking ( =No smoking is allowed (here) ). (禁止吸烟) No parking. (禁止停车) 5. 动名词的复合结构作主语 当动名词有自己的逻辑主语时,常可以在前面加上一个名词或代词的所有格,构成动名词的复合结构 (这时,名词或代词的所有格做动名词的逻辑主语)。 动名词的复合结构也可以在句中作主语。例如: Their coming to help was a great encouragement to us.
二、动名词作宾语 1.作动词的宾语 某些动词后出现非限定性动词时只能用动名词作宾语,不能用不定式。常见的此类动词有: admit, appreciate, excuse, stand, advise, allow, permit, avoid, consider, enjoy, finish They went on walking and never stopped talking.他们继续走,说个不停。 I found it pleasant walking along the seashore.在海滩上走真是乐事。 Mark often attempts to escape being fined whenever he breaks traffic regulations. 每当马克违反交通规则时,他常常企图逃避罚款的处分。 2.作介词的宾语 We are thinking of making a new plan for the next term. 我们正考虑为下学期制定新的计划。 Shall we have a rest or get down to doing our work? 我们休息呢还是开始干活? 3.作形容词的宾语 The music is well worth listening to more than once. 这种曲子很值得多听几遍。 We are busy preparing for the coming sports meet. 我们正为马上到来的运动会忙着做准备。
三、动名词作表语 动名词作表语时句子主语常是表示无生命的事物的名词或what引导的名词性从句。 表语、动名词与主语通常是对等的关系,表示主语的内容,主语、表语可互换位置。 Your task is cleaning the windows. 你的任务就是擦窗户。 (Cleaning the windows is your task.) What I hate most is being laughed at. 我最痛恨的就是被别人嘲笑。 (Being laughed at is what I hate most.)
四、动名词作定语 动名词作定语往往表示被修饰词的某种用途。如: a walking stick =a stick for walking=a stick which is used for walking a washing machine=a machine for washing=a machine which is used for washing a reading room=a room for reading=a room which is used for reading a measuring tape=a tape for measuring=a tape which is used for measuring sleeping pills=pills for sleeping=pills which is used for sleeping
