非谓语动词——分词

1、教学重点：掌握分词这一语法知识。了解这一语法知识在高考中的应用。命题趋势：分词的考点依次为作状语，作定语，做宾补及表语。一些固定的基本知识应记牢 知识点回顾：1. 分词的基本概念：分词也是非谓语动词之一。分词在形式上有两种形式：（1 ）现在分词，动词原形 + ing （同动名词形式）（2 ）过去分词，（规则动词）动词原形+ ed（不规则动词）构成没有什么规律2. 分词时态语态一览表非谓语动词形式时态/语态主动形式被动形式分词一般式doi ngBeing done完成式Having doneHaving bee n完成进行式Having bee n doing（基本不用）否定形式：not + 现

2、在分词3.分词在句中所能充当的成分主语宾语表语定语状语补语现在分词XX-VVVV过去分词XXVVVV4.分词的用法（1）分词做表语 跟在系动词之后等系分词做表语，一般跟在 be, get, become, look, sou nd, feel, keep, rema in, grow, seem, appear动词后面。现在分词做表语：一般表主动或主语的性质和特征。含有“令人.”的意思。主语多数为物。过去分词做表语：一般表示被动或主语所处的状态。含有“感到.”的意思。主语多数情况是人。例如：The n ews sou nds en courag ing.His father seems ple

3、ased with his results. 做表语的过去分词与被动语态中的过去分词的区别被动语态表示主语受到的动作表示主语的动作，而作表语的分词表示主语所处的状态。The blackboard was broke n by LiMing.The blackboard is broke n. 作表语的现在分词和进行时态的现在分词的区别作表语的现在分词表示主语的特征和性质。The situati on in our cou ntry is en couragi ng.进行时态中的分词表示主语正在进行的动作。The situati on in our cou ntry is en couragi

4、ng the people.be,但在进行结构中，则不可以。因为进行时的另外，在分词作表语的结构中，可以用其它系动词来代替 句型必须是 be + doing 。The news is surprising. = The news sounds surprising. 分词、动名词和不定式作表语的区别 分词作表语：主要是表示主语的特点和所处的状态 主语和表语的位置不可以互换。 动名词和不定式作表语：主要是表示主语的具体内容。主语和表语的位置常常可以互换。The film is disappointing. 这部电影令人失望。We are disappointed with the film. 我

5、们对这部电影感到失望。My job is teaching English. = Teaching English is my job.Our aim is to enter the universities. = To enter the universities is our aim.（2）分词作定语 一般来讲，和分词做表语一样，现在分词修饰事物，过去分词修饰人。cheered.When they heard the exciting news, they got excited. Then the excited people shouted and 当他们听到这一激动人心的消息时，他们

6、变得激动起来。然后这些激动的人们大声叫喊，欢呼 何时用现在分词的被动语态形式？ 如果一个及物动词作定语，既要表达进行意味，又要表达被动意味时，用此形式。The question being discussed is very important.= The question that is being discussed is very important.Do you know the boy being punished by our teacher?= Do you know the boy who is being punished by our teacher? 如果指的是将来的动作

7、就要用不定式的被动形式（或定语从句）来表示。 何时用过去分词作定语？ 过去分词包含完成和被动意味，一般表示的动作是在谓语动词所表示的动作之前发生。This is a picture painted by my father.= This is a picture that was painted by my father.（3）分词作宾语补足语I heard someone calling me.I had a decayed tooth pulled off. 我让大夫把我一颗蛀牙拔了。常用的动词有：感觉动词： hear, see, notice, watch, feel, find, le

8、ave 使役动词： make, let, have, get, keep 现在分词和过去分词做宾补的区别 现在分词：与句子的宾语是主动关系，它表示动作的进行。过去分词：与句子的宾语是被动关系，它表示动作的完成和结果。I heard someone calling me.（ someone calling me = someone is calling me.）I heard my name called.（ my name called = my name was called.）We found the snake eating the eggs.We found the eggs eate

9、n by the snake. 过去分词在动词have, get两词后面作宾语时，常常表示这个动作不是由主语完成的，而是由别人完成的，还有一种情况就是表示这是主语的经历。You' d better have （get） the dan gerous buildi ng pulled dow n.你最好叫人把这座危楼推倒了。How ofter do you have （get） your hair cut?你每隔多久理一次发？LiMi ng had his bike stole n.李明的自行车被偷了。(是主语的一种经历，遭遇) 重要的词组：make on eself donemake

10、on eself un derstood = to make one' s meaning clear to othersmake on eself heardI can ' t make myself understood because of my broken English.I didn ' t make myself heard because a lot of people cried in the hall. 现在分词、过去分词和不定式作宾补的区别形式语态内容被动语态现在分词v + ing与宾语是主动关系动作正在进行还没有 结束没有变化过去分词v + ed

11、与宾语是被动关系动作已经结束没有变化不定式不带to，动词原 形与宾语是主动关系动作发生了，全过程已结束to要还原例如：Do you hear some one calli ng you?(现在分词)(=Some one is calli ng you, do you hear?)Yes, I did. I heard him call me several times.(不定式)Oh, you mean you hear your n ame called several times.(过去分词)(=Your n ame was called several times, do you hea

12、r?)Whe n he was decorat ing his house, he got the bedroom pain ted first.(过去分词作宾补)当他装修他的房子时，他首先把卧室粉刷了。Whe n he was decorati ng his house, he had some workers paint his bedroom first.(不定式作宾补)当他装修他的房子时，他首先让工人把卧室粉刷一新。In order to finish it, he had the workers painting his bedroom all the day and night.为

13、了完成它，他让工人们从早一直干到晚。<1>由省去to的不定式构成的符合宾语在变为被动语态时，要把原来省去的小品词to还原，但let这个词例外，被动语态时，to可还原，也可省略。I watched the boy cross the street.The boy was watched to cross the street.The teacher let the students write the composition at class.t The students were let (to) write the composition at class.<2>ha

14、vedo这一句型不可以变为被动式，而makedo和letdo则可以。The boss had Tom clea n the room.t Tom was made to clea n the room.(V)Tom was had to clea n the room.(X)<3>fi nd的用法find +宾语+ doi ng（宾补）(V)find +宾语+ done（宾补）(V)find +宾语+不定式（V）He found a wallet lying on the ground.He found the city changed a lot.He found them ch

15、a nge the city.(x)<4>seat 和 sit 的用法Please be seated. = Please sit down.What surprised me most was to see some of the village people seated (sitting) on the benches at the end of room.最使我惊奇的是看见村民们坐在房后的长登上。(此句中的 seated 不能写成 seating ，但可以写成 sitting ) <5>如果有一系列动作作宾语时，一般用不定式，而不用现在分词。I saw her

16、enter the room, sit in a chair, open a book and begin to read. 我看见她走进房间，坐在一把椅子上打开一本书开始读起来了。( 4 )分词作状语 分词和分词短语可以在句子中作状语来修饰谓语动词或整个句子，表示动作发生的时间、原因、条件、结 果、让步或伴随等情况。但分词状语一般表示一个次要的动作。分词作状语时，一般都可以变为相应的状 语从句或并列句。分词作时间状语 <1>分词所表示的动作一发生，谓语动词表示的动作立即发生，可以用分词短语作状语。 分词位置：放在前面。可以译为：“当的时候”可以换成： on + 动名词结构。常用的

17、动词多是表示一个极短暂动作的动词，如 hear, see, return, look, open, close, arrive, leaveHearing the bad news, they couldn't help crying.= When they heard the bad news they couldn't help crying.= On hearing the bad news, they couldn't help crying.当听到这个不幸的消息时，他们情不自禁地哭了起来。<2>分词所表示的动作在进行过程中，谓语动作发生了，此时可以

18、用分词短语作状语，但一般在它的前面加 上 when 或 while 。分词位置：前后都可以。可以译为：“当时”While playing the piano, she got very excited.= While she was playing the piano, she got very excited. <3>分词所表示的动作完成了之后，谓语动词所表示的动作才发生，用分词的完成形式作状语。 分词位置：放在句子前面。可以译为：“在之后”。可以换成： after + 动名词这一结构。Having turned off the radio, he began to go ove

19、r his lessons.= After he had turned off the radio, he began to go over his lessons.= After turning off the radio, he began to go over his lessons.分词作原因状语 分词短语作原因状语时，相当于一个原因状语从句，同时也可以转变为一个原因状语从句，分词的完成形 式也经常用来作原因状语。<1>分词所表示的动作和谓语动词所表示的动作同时发生或几乎同时发生时，用分词的一般形式。 Forgetting his manners, he put his f

20、eet up on the desk.= As he forgot his manners, he put his feet up on the desk.忘掉了他的举止（要文明了）他把脚放在书桌上。Being so angry, he couldn' t go to sleep.= because he was so angry, he couldn' t go to sleep.因为太生气了，他不能入睡。<2>分词所表示的动作在谓语动词所表示的动作之前发生，用分词的完成式。Having been to the Great Wall many times, he

21、didn' t go last week.= Because （As） he had been to the Great Wall many times, he didn' t go last week.因为他已经去过长城许多次了，上周他就没去。 分词作条件状语 分词短语有时表示一种假设情况，相当于一个条件从句，这种情况下，有时在分词短语前加上 of, unless 是条件更明确。Given more attention, the trees could have grown better.= If they had been given more attention, the

22、 trees could have grown better. 如果对这些树再多注意些，它们可能长得更好。 分词作让步状语 分词短语作让步状语时，相当于一个让步状语从句，有时分词前可带连词 although, whether, even if, even though 。Although working from morning till night his father didn' t get enough food.= Although his father worked from morning till night he didn' t get enough food.

23、虽然他父亲从早到晚的拼命干，但是他还是挣不够吃的。 表示方式或伴随情况 分词短语表示方式或伴随情况是比较常用的，它用来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。他没有相应的状语从句可转换，但可以用并列句来转换。They came into the classroom, singing and laughing.= They sang and laughed and they came into the classroom. 他们又唱又笑地走进教室。 分词作结果状语分词短语作结果状语时，通常放在句末，中间有逗号，有时为了突出结果，分词前带有 thus

24、.The bus was helped up by the snowstorm, thus causing the delay. = The bus was helped up by the snowsorm, so it caused the delay. 分词作状语和不定式作状语的区别 分词和不定式虽然都可以当状语，但区别较大。 不定式作状语：主要是作目的状语和结果状语，还有一些作原因状语。 分词作状语：一般表示时间、原因、条件、让步、方式、伴随等情况（用作目的和结果状语的时候不多） I 'm sorry to hear that.The doctor, not wishing t

25、o make her nervous, didn ' t fully explain the seriousness of her condition. 分词作状语时需注意事项<1>分词短语作状语时，他的逻辑主语通常应是句子的主语，这一点需特别注意句子的主语是 the city ）（句子的主语是 you ）（X）认为按照Seen from the hill, the city is beautiful.
