英语分词使用方法分词也是一个限定动词，分为现在分词和过去分分词也是一个限定动词，分为现在分词和过去分词。它保留着动词若干特征，又含有形容词、副词。它保留着动词若干特征，又含有形容词、副词特征。分词有时态和语态改变，又带有宾语并词特征。分词有时态和语态改变，又带有宾语并能被状语修饰。分词在句中主要作定语、状语用，能被状语修饰。分词在句中主要作定语、状语用，作表语也十分普遍。作表语也十分普遍。一、分词形式一、分词形式主动语态主动语态普通式普通式doing,完成式完成式havingdone被被动语态动语态beingdone,havingbeendone其否定形其否定形式是在式是在doing之后加上之后加上not。第1页其否定形式是在doing之后加上not。二、分词作用二、分词作用分词在句中可作定语、表语、状语、补足语等。1、作定语分词作定语有两种形式。它能够放在被修饰名词之前，称为前置定语。有放在被修饰名词之后，称为后置定语。（1）前置定语He is a_(promise)young man.他是一个有前途年轻人。promisingMake less noise.Theres a _(sleep)child.不要出太大声音，有个孩子在睡觉。sleepingWe only sell _(use)books.我们只卖用过书。used（2）后置定语The young man_(sit)between John and Mary is the editor of the campus newspaper.坐在约翰和玛丽之间那个年轻小伙子是校园报编辑。sittingThe bridge _(build)last month needs repairing.上个月建造那座桥需要修理 built第2页（3）过去分词作定语有既可前置也可后置。如：All the _windows have been repaired.全部坏了窗户已经修理好了。(break)All the windows _ have been repaired.broken（4）分词短语作定语必须置于被修饰词之后，相当于一个定语从句。如：Those_(wish)to join this club should sign here.想加入本俱乐部人在这里署名。(=Those who wish to join the club should sign here.)wishingThe man,_(have disturbed)so badly,almost lost his memory.因为被严重困扰，这个人几乎失去了记忆。(The man,who had been disturbed so badly,almost lost his memory.)having been disturbed（4）完成体分词普通不作定语，若要表示完成意义最好用定语从句。如：我们普通不说：The girl having won the race is my deskmate.而常这么说：The girl who has won the race is my deskmate.第3页（5）非限定性完成体作定语或假如分词所修饰词是泛指则没有这个限制。如：Anyone _(have passed)the test has got a prize.任何经过考试人都能得到一份奖品。having passedCharlie,having lived in Paris for years,decided to return to London.在巴黎呆过多年，查理决定重返伦敦。（6）过去分词作定语在意义上有两种可能：表示被动和完成，只表完成。如：the question _(discuss)yesterday 昨天讨论问题 （既表示被动也表示完成）discussedthe _(fall)leaves 落下树叶 (只表示完成，不表示被动)fallen在英语中只表完成不表被动往往是一些不及物动词过去分词，常见有：the changed situation,a newly returned sudent等。第4页2、作表语分词作表语表示主语某种性质或状态。如：The shops have remained shut for a week.这家商店关门一周了。What you said is really inspiring.你所说真令从鼓舞。3、作宾语补足语I oftentimes hear a girl singing downstairs.我有时听到楼下有一个小姑娘在唱歌。I find some students in this school often punished by the teachers.我发觉这所学校学生经常被老师处罚。第5页4、作状语(注意主语和分词一致性)分词在句中作状语，能够表示各种不一样语义内容。它能够表示时间、原因、让步、结果、方式、条件等。如：（1）表示时间Arriving in Paris,I lost my way.到了巴黎，我迷了路。The hunter walked slowly in the forest,followed by his wolf-dog.猎人在森林里慢慢地走着，后面跟着一只狼狗。表示与主句中谓语动词同时性现在分词强调时间意义时，分词前能够加上while,when等隶属连接词，但as没有这种使用方法。如：Dont talk while having dinner.吃饭时不要说话。When crossing the street,do be careful.过马路时要小心。第6页（2）表示原因表示原因分词短语普通置于句首。Having lived in London for years,I almost know every place quite well.在伦敦住过多年，我几乎对每个地方都很熟悉。Seriously injured,he had to be taken to hospital.因为伤得严重，只好把他送往医院。（3）表示结果The fire lasted nearly a month,leaving nothing valuable.大火连续了近一个月，几乎没剩下什么有用东西。Football is played in more than 80 countries,making it a popular sport.80多个国家都踢足球，所以足球成了一个很流行运动。（4）表示方式I stood by the door,not daring to say a word.我站在门旁，不敢说一句话。第7页（5）表示条件United,we stand;divided,we fall.联合起来我们就能站立，分裂我们必定倒下。Being more careful,you can make fewer mistakes.假如你更细心，你会犯更少错误。强调条件时，能够在前面加上unless,once等。如：You shouldnt come in unless asked to.不让你进来你不准进来。Once losing this chance,you cant easily find it.一旦失去这次机会你就极难找回。第8页二、分词独立主格结构二、分词独立主格结构分词短语作状语时，其逻辑主语就是句子主语，不然，就必须在分词前另加上自己逻辑主语（名词或主格代词）这个结构叫独立主格结构或分词复合结构。1、独立主格结构常放在句首。表示时间、条件、原因时，其作用分别相当于个时间、条件、原因状语从名句。表示伴随方式时，相当于一个并列句。如：Supper finished(=After supper was finished),we started to discuss the picnic.吃完晚饭，我们开始讨论野餐事。All the tickets having been sold out(=As all the tickets having been sold out),we had to wait for the next weeks show.全部票都卖出去了，我们只好等着看下周演出。第9页2、表示独立主格结构中being常省略。如：The football match(being)over,crowds of people poured out into the steet.足球赛五结束，从群便涌到大街上。Nobody(being)in,I didnt enter the hall.里面没有些人，我没进大厅。3、表示伴随方式独立主格结构，有时可用“with宾语宾语补足语”结构来替换。如：He lay there thinking,his hands behind his head(with his hands behind his head).他双手放在头下，躺在那里思索着。The river looks more beautiful,flowers and grass growing on both sides(=with flowers and grass growing on both sides).这条河看上去愈加漂亮，因为两岸长满了鲜花和绿草。第10页with宾语宾语补足语结构是英语中常见惯用结构，其宾语补足语能够是现在分词、过去分词、不定式、形容词、副词、介词短语等，在句中可作定语，也可作状语，表示原因、方式等。如：The children looked at us,with their eyes opening wide.孩子们眼睛睁得大大地看着我。I would miss the train,with no one to wake me up.没人叫我，我会错过火车。The river with grass and flowers on both sides runs through our schoolyard.这条两河两岸长满鲜花和绿草正从我们校园穿过。With the examinations over,we had a long time to rest.考试结束了，我们有一段长长时间能够休息。第11页4、有些惯用分词短语在句里能够没有逻辑上主语而独立存在，它们往往作为句子独立成份来修饰全句。如：generally/strictly/roughly/broadly/narrowly speaking,judging from/by,considering,supposing,providing,provided等。如：Talking of the computer,I like it very much.谈到电脑，我非常喜欢。Considering the time,we have decided to start early tomorrow morning.考试到时间，我们已经决定明早一早出发。第12页Employ vt.使采、利用 ，雇用，使忙于,使从事于She employs her time
