英语分词用法,英语分词用法,分词也是一种限定动词，分为现在分词和过去分词。它保留着动词的若干特征，又具有形容词、副词的特征。分词有时态和语态变化，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，作表语也十分普遍。,一、分词的形式,语态 主动语态 现在分词被动语态 过去分词现在分词有以下这些形式 主动形式 被动形式一般式 doing being done 完成式 having done having been done,现在分词的完成式表示分词所表示的动作在句子的谓语动词之前发生。过去分词一般表示完成的和被动的动作，只有一种形式。,二、分词的作用,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。它可以放在被修饰的名词之前，称为前置定语。有的放在被修饰的名词之后，称为后置定语。,（1）前置定语,He is a promising young man.他是一个有前途的年轻人。Make less noise.Theres a sleeping child.不要出太大声音，有个孩子在睡觉。We only sell used books.我们只卖用过的书。,（2）后置定语,The young man sitting between John and Mary is the editor of the campus newspaper.坐在约翰和玛丽之间的那个年轻小伙子是校园报的编辑。The bridge built last month needs repairing.上个月建造的那座桥需要修理。,（3）过去分词作定语有的既可前置也可后置。,All the broken windows have been repaired.所有坏了的窗户已经修理好了。All the windows broken have been repaired.,（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,Those wishing to join this club should sign here.想加入本俱乐部的人在这里签名。(=Those who wish to join the club should sign here.)The man,having been disturbed so badly,almost lost his memory.由于被严重困扰，这个人几乎失去了记忆。(The man,who had been disturbed so badly,almost lost his memory.),（4）完成体的分词一般不作定语，若要表达完成意义最好用定语从句。,我们一般不说：The girl having won the race is my desk-mate.而常这样说：The girl who has won the race is my desk-mate.,（5）非限定性的完成体作定语或如果分词所修饰的词是泛指则没有这个限制。,Anyone having passed the test has got a prize.任何通过考试的人都能得到一份奖品。Charlie,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。,the question discussed yesterday 昨天讨论的问题（既表示被动也表示完成）the fallen leaves 落下的树叶(只表示完成，不表示被动)在英语中只表完成不表被动的往往是一些不及物动词的过去分词，常见的有：the changed situation,a newly returned student等。,2、作表语,分词作表语表示主语的某种性质或状态。如：The shops have remained shut for a week.这家商店关门一周了。What you said is really inspiring.你所说的真令从鼓舞。,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.我发现这所学校的学生经常被老师惩罚。,4、作状语,分词在句中作状语，可以表示各种不同的语义内容。它可以表示时间、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。Having finished his homework,he went to sleep.表示与主句中谓语动词同时性的现在分词强调时间意义时，分词前可以加上while,when等从属连接词，但as没有这种用法。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。,2）表示原因,表示原因的分词短语一般置于句首。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.由于伤得严重，只好把他送往医院。,3）表示结果,The fire lasted nearly a month,leaving nothing valuable.大火持续了近一个月，几乎没剩下什么有用的东西。Football is played in more than 80 countries,making it a popular sport.80多个国家都踢足球，因此足球成了一种很流行的运动。,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。,5）表示条件,United,we stand;divided,we fall.联合起来我们就能站立，分裂我们必然倒下。Being more careful,you can make fewer mistakes.如果你更细心，你会犯更少的错误。强调条件时，可以在前面加上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很难找回。,二、分词的独立主格结构,分词短语作状语时，其逻辑主语就是句子的主语，否则，就必须在分词前另加上自己的逻辑主语（名词或主格代词）的这个结构叫独立主格结构或分词的复合结构。,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。,Supper finished(=After supper was finished),we started to discuss the picnic.吃完晚饭，我们开始讨论野餐的事。All the tickets having been sold out(=As all the tickets having been sold out),we had to wait for the next weeks show.所有的票都卖出去了，我们只好等着看下周的演出。,2、表示独立主格结构中的being常省略,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.里面没有人，我没进大厅。,3、表示伴随方式的独立主格结构，有时可用“with宾语宾语补足语”的结构来替换。,He lay there thinking,his hands behind his head(with his hands behind his head).他双手放在头下，躺在那里思考着。The river looks more beautiful,flowers and grass growing on both sides(=with flowers and grass growing on both sides).这条河看上去更加漂亮，因为两岸长满了鲜花和绿草。,with宾语宾语补足语的结构是英语中常见常用的结构，其宾语补足语可以是现在分词、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。,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，我会错过火车的。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，我们有一段长长的时间可以休息。,4、有些惯用的分词短语在句里可以没有逻辑上的主语而独立存在，它们往往作为句子的独立成分来修饰全句,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.考虑到时间，我们已经决定明早一早出发。,Thank you,
