1、英语语法大攻克非谓语动词全面 非谓语动词动词不定式、分词(现在分词，过去分词)和动名词统称为非谓语动词。现代英语将现在分词和动名词合为一大类叫作V + ing形式。这些动词的形式不能在句中单独作谓语用，因而没有语法主语。但可以有逻辑主语。由于没有语法主语，也就不受人称和数的限定，因为不是谓语，也就没有时态和语态，但这些词仍能表示动作和状态，所以仍有表示与其他动词相对时间关系的形式。由于与其它词有逻辑上的主谓关系，因此也有表示主、被动的形式，同时也有自己的宾语和状语，一起构成非谓语动词的短语(动词不定式短语，分词短语，动名词短语)。（一）动词不定式动词不定式由“to+ 动词原形”构成，如：to
2、study, to play，动词不定式虽然不能作谓语动词用，但仍留着动词的特征，它可以带有所需要的宾语或状语而构成动词不定式短语，如：to study hard, to play table tennis。 1、动词不定式的形式变化：动词不定式有下列时态和语态的形式变化。语态式一般式完成式进行式完成进行式主 动to buildto have builtto be buildingto have been building 被 动to be buildto have been build 2、动词不定式的基本用法：动词不定式能起名词、形容词和副词的作用，可在句中作主语、表语、宾语补足语、定语和
3、状语用，如： （1）作主语：To help each other is good.（动词不定式作主语时，一般可用it作形式主语，而将作主语的动词不定式置于句末，如：It is good to help each other. （2）作表语：My job is to drive them to the power station every day. 动词不定式在系动词be之后作表语，与表示将来时的be + 动词不定式结构有所区别，如：Our plan is to set up another middle school for the peasants children.我们的计划是给农民子弟
4、再成立一所中学。（句中的谓语动词为is，动词不定式to set up 为表语，主语为plan，但plan并不是动词不定式的逻辑主语，即动词不定式 to set up所表示的动作不是主语plan产生的。）We are to set up another middle school for the peasants children.我们将为农民的子弟再成立一所中学。（句中的are to set up整个结构为句中谓语，主语为we，同时也是动词不定式to set up所表示的动作的逻辑主语，即动词不定式to set up所表示的动作是由we产生的）。不定式作表语不定式作表语常表示将来的动作，主语常
5、常是表示意向、打算、计划的词，如wish, idea, task, purpose, duty, job等。【例如】The most important thing for ones health is to have plenty of exercise.My chief purpose has been to point out the difficulties of the matter.The purpose of the organization is to greet all new comers to the city and to provide them with any n
6、ecessary information.What I wanted was to get the work done as quickly as possible. （3）作宾语：作及物动词的宾语，如：She wishes to be a musician.；作某些形容词的宾语：可以有动词不定式为宾语的形容词一般有glad, sorry, afraid, pleased, determined, willing, eager, anxious, ready, sure等，如：I am determined to give up smoking.；动词不定式一般不作介词的宾语，但动词不定式之前
7、如有疑问词时，就可作介词的宾语，如：Can you give us some advice on what to do next? （接不定式作宾语的动词：want, wish, hope, decide, agree, plan, promise, refuse, afford, happen, would like.want、wish、hope、decide、happen、refuse.wouldlike.afford,agree,apply,arrange,ask,attempt,beg,begin,care,choose,claim,consent,demand,desire,dete

9、省去to的不定式）（4）作宾语补足语，如：Tell the children not to play on the street. 如果句中的谓语动词为see, hear, watch, notice, have, make, let等，作宾语补足语的动词不定式须将to省去，如：I saw a little girl run across the street. （5）动词不定式在句中作宾语，如带有宾语补足语时，须先用it作形式宾语，而将该动词不定式后置，如：I dont think it right to do it that way. （6）作定语：动词不定式作定语时，须位于被其修饰的名词
10、或代词之后，如：Is this the best way to help him? 和定语用的动词不定式如果是不及物动词，不定式后面就要用必要的介词，如：He is the man to depend on. 如果被不定式修饰的名词为place, time, way，不定式后面的介词，习惯上可以省去，如：The old man is looking for a quiet place to live. （7）作状语：动词不定式可以作下列的状语：目的状语： Every morning he gets up very early to read English. 为了强调不定式表示目的的作用，可在
11、不定式前加in order to或so as to（以便或为了），但应注意in order to位于句首或句中均可，而so as to不能位于句首，如：She reads China Daily every day in order to (so as to) improve her English. 将表示目的的不定式置于句首，也可强调目的的作用，如：To master a foreign language, one must work hard at it. 结果状语：They lived to see the liberation of their home town.他们活到亲眼见到了
12、他们家乡的解放。too + 形容词或副词 + 动词不定式，表示“足能”的结果，如：You are old enough to take care of yourself now.不定式常用来修饰形容词，构成下列词组：be able to, be afraid to, be apt to, be bound to, be certain to, be easy to,be eager to, be fit to, be likely to, be ready to, be sure to, be unable to, be unwilling to, be willing to等。3、疑问词 +
13、 动词不定式：疑问代词和疑问副词后可加动词不定式构成不定式短语，在句中可作主语、表语或宾语，如：How to prevent them from swimming in this river is a problem.4、复合结构不定式：由for + 名词（或代词宾格）+ 动词不定式即构成复合结构的动词不定式。其中for本身无意义。for后面的名词或代词是不定式的逻辑主语，这种不定式在句中可作主语、表语、宾语、定语或状语，如：It is very important for us to get everything ready for the harvest. 当作表语用的形容词表示不定式的逻
14、辑主语的性质或特征时，就用介词of而不用for引出不定式的逻辑主语，这些形容词一般有good, nice, kind, wise, silly, stupid, foolish, right, wrong, careless, impolite等，如：It is very kind of you to help him every day.5、动词不定式的否定式：动词不定式的否定式是由not + 动词不定式构成，如：Its wrong of you not to attend the meeting. 6、动词不定式的时态形式所表示的时间关系：（1）一般式：动词不定式一般式所表示的动作是和谓语
15、动词所表示的动作同时发生，但在多数情况下，是在谓语动词所表示的动作之后发生，如：We decided to plant more trees this spring.（其后），They often watch us play table tennis.（同时）；（2）完成式：动词不定式完成式所表示的动作发生在谓语动词所表示的动作之前，如：I am sorryto have kept you waiting.（3）进行式：动词不定式进行式所表示的动作正在进行中，而且与谓语动词所表示的动作同时发生，如：She happened to be writing a letter in the room
16、when I came in. 7、动词不定式的被动语态用法：如果动词不定式的逻辑主语为这个不定式所表示的动作的承受者时，不定式一般就用被动语态形式，如：What is to be done next hasnt been decided yet. 练习（一）1. - Can you ride a horse? - No, I never had the chance _.

21、he house. A. open the door and go into B. to open the door and to go into C. open the door and to go into D. open the door and went into（二）动名词动名词形式仍保留有动词的特征，可以带有其所需要的宾语或状语而构成-ing短语。 1、动名词的形式：现在以及物动词make 和不及物动词go为例，将其-ing各种形式列表如下：动词 语态形式及物动词make不及物动词go主动语态被动语态主动语态一般式makingbeing madegoing完成式having mad
22、ehaving been madehaving gone 2、动名词的基本用法。 （1）作主语：Seeing is believing.百闻不如一见。Talking is easier than doing. ing作主语时，如果其结构较长，可用it作形式主语，而将作主语的-ing后置。如：It isnt much good writing to them again. Its no use waiting here. （2）作表语：Her job is washing and cooking. My hobby is collecting stamps. （3）作宾语：作及物动词的宾语。Sh
23、e likes drawing very much.；作某些短语动词的宾语。 Mary is thinking of going back to New York.； do+限定词（my, some, any, the等）+ -ing，表示“做事”之意，如：We often do our cleaning on Saturday afternoon. Will you do any shopping on Saturday this afternoon? 作介词的宾语：Her sister is good at learning physics.；作形容词worth, busy等的宾语：Thi
24、s book is well worth reading. ing作宾语带有宾语补足语时，要用it作为形式宾语，而将作宾语的-ing后置，如：We found it no good talking like that. Do you think it necessary trying again? （接动名词作宾语的动词/短语：enjoy, practice, finish, mind, admit, allow, deny, avoid, keep, suggest, consider, advise, imagine, miss, be busy, be worth, feel like,
25、 cant/ couldnt help, look forward to, be used to等。介词后面一般要用动名词作宾语） （4）作定语：The sleeping child is only five years old. Do you know the man standing at the gate? 注：-ing形式作定语用时，如果-ing只是一个单词，就位于其修饰的名词之前，如果是-ing短语，就位于其修饰的名词之后，-ing作定语时，被-ing所修饰的名词就是该-ing的逻辑主语。另外，-ing作定语用时，其动作和句子谓语动词所表示的动作是同时进行的，如果不是同时进行的，就不
26、能用-ing作定语，要使用定语从句，如：The girl who wrote a letter there yesterday can speak English very well. （5）作宾语补足语：We can see steam rising from the wet clothes. 注：当-ing在复合宾语中作宾语补足语用时，句中宾语就是这个-ing的逻辑主语，可以带有这种复合宾语的动词有see, watch, hear, observe, feel, find, have, keep等。 （6）作状语：时间状语：Seeing Tom, I couldnt help thinki
27、ng of his brother. 分词在句中作时间状语时，其前一般可加when或while，如：When crossing street, you must be careful. 原因状语：Being ill, he didnt go to school yesterday. 方式或伴随状语：Mary stood at the school gate waiting for Betty. 3、主动语态-ing完成式的基本用法。主动语态-ing完成式所表示的动作发生在谓语动词所表示的动作之前，一般在句中作时间或原因状语用。句中的主语是它的逻辑主语，并且是它所表示的动作的执行者，如：Havi
28、ng answered the letter, she went on to read an English novel. 4、被动语态-ing一般式的基本用法。被动语态-ing一般式所表示的动作是一个正在进行中的被动动作，而且这个被动动作也是和句中谓语所表示的动作同时发生的。它一般在句中作定语或状语用。如：The truck being repaired there is ours. 5、被动语态-ing完成式的基本用法。被动语态-ing完成式所表示的动作发生在谓语动词所表示的动作之前，在句中一般作状语用。如：Having been shown the lab, we were taken
29、to see the library. 6、-ing形式的复合结构。在-ing前加物主代词或名词所有格即构成-ing的复合结构。其中的物主代词或名词所有格为-ing的逻辑主语。这种结构在句中可作主语、宾语或表语，如：Your smoking and drinking too much will do harm to your health. 但在口语中，这种结构如作宾语用，其中的物主代词常用人称代词的宾格，名词的所有格常用名词的普通格代替，如：She insisted on Peters (or Peter)going there first. 7、-ing形式与动词不定式在句中作主语、表语、
30、宾语时的区别。一般说来，表示一个比较抽象或泛指的动作时多用-ing形式。表示一个具体某一次的动作时，多用动词不定式，如：Our job is making steel. She likes playing the piano, but she doesnt want to play it today. 8、-ing形式与动词不定式在句中作定语的区别。-ing形式作定语用时，其动作一般与句中谓语动词所表示的动词同时发生，而动词不定式作定语时，其动作一般发生在句中谓语动词所表示的动作之后。如：The girl writing a letter there can speak English ver
31、y well./I have three letters to write. 9、-ing形式与动词不定式在作宾语补足语时的区别。（1）不定式作宾补时，其动作一般发生在谓语动词所表示的动作之后，如：I have told them to come again tomorrow.（2）在see, watch, hear, feel等之后，如果用-ing形式作宾补，表示其动作正在进行中，而用不带to的不定式作宾补时，不定式所表示的动作是一个动作的过程，如：I hear her singing in the room.我听见她正在屋里唱歌。 I hear her sing in the room.我
32、听见她在屋里唱过歌。 10、-ing形式与动词不定式在句中作状语的区别。-ing形式在句作状语表示时间、原因、方式或伴随情况，而动词不定式一般式在句中作状语时，一般是作目的或结果状语，如：Not receiving his letter, I wrote to him again./ I looked into the window to see what was going on inside.练习（二）1.
