现在分词(Present Participle),又称-ing形式,现在进行式,动名词 1.作主语:通常被看作是单数不可数名词,所以谓语动词用第三人称单数形式. Driving fast is very dangerous. Swimming is my favourite sport. Painting is an art. Hearing the bad news made him cry. 注意:现在分词作主语时,和动词不定式一样,当它是较长的短语时,常常用it作形式主语,而把现在分词放到句末. 如:It's nice spending the holiday at the beach. It's tiring working late. 现在分词作主语时的常用句型: a waste of time no good/no use It +be+ little/hardly any use + V-ing分词 not/hardly worth worth/worthwhile 如:It's no use complaining. It's no good smoking a lot. It's a waste of time doing such a thing. no no sense in(没有道理) There +be+ no point in(毫无意义) +V-ing分词 no use in Nothing worse than(没有比...更糟糕的) 如:There was no knowing what he was doing. There is no point (in) doing so.这么做,毫无意义. 经常跟在it +be后面的形容词,然后接动名词作实际主语的形容词还有: Odd古怪的\x09Crazy疯狂的\x09Hopeless无望的\x09Nice Funny好笑的\x09Foolish愚蠢的\x09interesting\x09Tiring累人的 better\x09terrible\x09Enjoyable愉快的\x09Pointless无意义的 2作表语:-ing分词作表语多和系动词be连用.注意:如果主语用了不定式,表语也要用不定式;同样地,如果主语用的是-ing分词,表语也应用-ing分词.即,作主语和表语的动词在形式上的一致. 如:Seeing is believing=To see is to believe. My favourite sport is swimming. Her only hobby(爱好) is collecting stamps. ☆注意:现在分词作表语和动词不定式作表语的区别在于:现在分词表示习惯性动作;而不定式表示一次性的具体动作. 如:My plan is to finish my homework before tomorrow. My favourite sport is swimming. 3. 作宾语 英语中,有相当一部分动词后,只能接-ing分词作宾语. 这类动词主要有: Admit承认\x09advise\x09Anticipate期望做.\x09Detest憎恨做. Defer推迟\x09suggest\x09Escape逃避做.\x09Quit停止做. Deny否认\x09Miss错过\x09Avoid避免做.\x09Tolerate忍受. Keep保持做.\x09Appreciate感谢.\x09Practise练习.\x09enjoy Mind介意\x09Consider考虑做\x09Risk冒险做.\x09Excuse原谅 如: Excuse me interrupting you. I enjoy reading newspapers. I suggest you should practise speaking English every morning. 注意:有一类动词后即可跟不定式作宾语,也可跟-ing分词作宾语.可以把这类动词分为三种类型:1)两种形式意义基本相同.2)两种形式略有差别.3)意义完全不同. A)两种形式意义基本相同的动词有:attempt, begin, cease(停止), continue, intend, start, commence(开始). 如:She started to cry/crying. What do you intend to do/doing next?你打算接下来做什么? He continued to work/working. B)两种形式意义略有差别的动词主要有:hate, like, dislike, love, prefer等. 如:I like playing basketball. I hate to trouble you. I prefer to go for a walk. I prefer singing songs. C)后跟不定式和-ing分词时,意义完全不同的动词有:remember, forget, regret., try, mean, chance(碰巧),cannot help...等.它们后面跟不定式表示动作还未发生,而跟现在分词表示动作已经发生. 如:I regret to do this thing. I regret doing such a thing. Mean to do 表示打算,意欲做某事:而mean doing表示“意味着,意思是” 如:I mean/plan to buy a house. Fighting means killing. Chance to do表示碰巧做某事;而chance doing表示冒险做某事、碰运气试着做某事 He chanced to meet his old friend in the street. He chanced taking part in that race. Cannot help to do表示不能帮忙做某事;Cannot help doing表示情不自禁,不由得做某事 如:I cannot help to do homework for you. I cannot help laughing. 4. 作介词宾语 除了我们已经谈到的“疑问词+不定式”可以作介词宾语外.通常情况下,只能用-ing分词作介词的宾语.但个别表示“除了.之外”的介词如“except, but, than”通常接不定式. 如:I can do nothing except/but wait. 后面跟-ing分词作介词宾语的短语结构主要有: A)“动词+介词+动名词” I am used to sleeping on the floor.(习惯于.) I am looking forward to meeting you. The rain stopped us from working. She objected to marrying him(反对) B)“形容词+介词+-ing分词” I am interested in playing basketball. Tom is responsible for breaking the glass. C)'名词+介词+动名词' There are many ways to do it/of doing it. He didn't go out for fear of raining. -ing分词的惯用搭配有: A)主语+have+fun/pleasure/a good time/trouble/difficulty+(in) doing sth 如:We had a lot of fun (in) playing basketball. I have trouble/difficulty(in) understanding him. B)“There is+difficulty/trouble/pleasure+(in) doing sth” 如:There is difficulty in passing the exam. There is trouble in learning a foreigh language. C)“be busy+(in) doing sth” I am busy in doing my homework. D) “What about/How about +-ing分词”(征求意见句型.怎么样) What/How about having a cup of tea? How about playing basketball with me? E)注意:有一类-ing分词和go搭配,表示“去(干.)”,这些分词大多与休闲娱乐的户外活动有关. 常用的有: boating\x09Camping野营\x09Climbing爬山 Driving驾车兜风\x09Dancing跳舞\x09Hiking徒步旅行 Hunting打猎\x09Fishing垂钓\x09running Jogging慢跑\x09Ridding骑马\x09Sailing航行 Shopping购物\x09Sightseeing观光\x09Skating滑冰 swimming\x09Walking散步\x09Window shopping逛街 如:We went boating yesterday. 5.作定语 单个分词作定语时放在所修饰名词前 a running boy the girl standing there (分词短语作定语,故置于所修饰名词之后) 并且一般都可以转化为一个进行时的定语从句 如: a boy who is running a girl who is standing there 注意:某些现在分词作定语时,已不再表示动作,已经从分词变为了形容词词性.如:an interesting story, an exciting match .这些也可以属于现在分词作定语,但是不能转化为相应的定语从句.但是可以有三级变化(原级、比较级、 最高级)和被某些副词如very修饰. 6.作宾语补语 只有两类动词可以加现在分词作宾补 1)感官动词或心理状态的动词:see,hear,watch,feel,notice,observe,find,listen to,look at 2)表示致使意义的动词:make, have,get,catch,leave,keep, let 注意:但是并不代表这些动词后的宾补形式都要用现在分词(有些后面可以加不带to的不定式作宾补) eg.I saw him singing now. 和 I saw him sing in the house. 注意 :宾语与作宾补的现在分词之间存在逻辑上的主谓关系,即宾语是现在分词动作的发出者. 7.作状语 分词作状语时的逻辑主语(即分词动作的发出者)一般要与句中主语保持一致.若逻辑主语和分词动作之间为主动,用主动.反之,用被动. A)作时间状语 如:.Walking in the street,I saw him.当我在街上走时,我看到他了 可以转化为一个时间状语从句:When/While I was walking in the street,I saw him. 注意:当我要强调正在进行的动作时 我们可以在分词前面加上when/while 那么上面的例句就可以改写为When/While walking in the street,I saw him.(其实这是省略了从句中的I was,因为从句的主语和主句一致). 如果句子为: When/While he was walking in the street,I saw him. 当他走在街上,我看到他了. 这里,由于从句主语和主句主语不一致,故不可省略. B)作条件状语 如: Working hard,you will succeed. (只要)努力工作,你就会成功. 可以转换为if引导的状语从句.即:If you work hard, you will succeed. C)作原因状语 如: Being ill,she stayed at home. (因为)生病,她留在家里 注意 being是常用来作原因状语的 这句可以转换为相应的原因状语从句:Because/As she was ill, she stayed at home. D)作让步状语 如. Having failed many times,he didn't lose heart. 有很多次失败,他没有灰心. =Although he had failed many times, he didn't lose heart. E)作结果状语 如: His friend died,leaving Tom a lot of money, 他的朋友死了,(所以)给汤姆留了很多钱. =His friend died, so he left Tom a lot of money. F)作方式状语 如:Please answer the question using another way. 请用另一种方式回答这个问题 G)作伴随状语,表示现在分词的动作正在进行中. 如: He sat on the chair, singing songs. They left the shop, satisfied. The worked for a whole day, exhausted. They watching TV in the living room, I was cooking in the kitchen. 8. 现在分词的独立主格 (1)独立主格,又叫独立结构,在句中作状语.它没有主语和谓语,只有逻辑上的主语,因此,它在句法上不是句子,而是一个独立于句子成分之外的独特结构形式. (2)独立主格结构可置于句首、句尾,用逗号与主句隔开. 独立主格结构可分为两部分,一部分是名词或代词(主格),起着逻辑主语的作用;另一部分由形容词、副词、名词、分词、不定式、介词短语等构成,表示前面名词或代词的状态、状况或动作. 如:He entered the room, his nose red with cold.(名词/代词+形容词) He lay on his back, his hands behind his head.(名词/代词+介词短语) He entered the classroom, a book in his hand. He lay on the bed, his eyes closed. A good student, he always studies very hard. Whatever the reason, Bob went aboard finally. (3)这和我们学过的”with的复合结构”是差不多的,只不过它要比独立主格多个with. (4)分词作状语时,其逻辑主语一般要与句中主语保持一致”不难发现我每次在叙述这句话时都加上”一般”二字 那也就是说也有特殊的时候 就是分词的逻辑主语不和句中主语保持一致 也就是拥有了自己的独自的逻辑主语 那么也就是该用独立主格的时候了. 如:Winter coming,it gets colder and colder.冬天来了 天变的越来越冷了 注意这句话,我们不难发现it在句中指代的是”天气” .那么当我把winter去掉的时候,那在形式上就是纯粹的分词作状语.那么我们也就是默认了coming的动作是由it(天气)发出来的.但是我们不妨翻译一下”当天气来的时候,天气变的越来越冷了.”显然句意不通.那么就是说coming的逻辑主语不是it(天气),也就是coming拥有自己的逻辑主语.那么也就是winter,因为coming的动作是由winter发出的. |
