1、1非谓语动词非谓语动词(一)动词不定式动词不定式、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)。动词不定式、过去分词及 v-ing 形式在句中均不能作谓语用
2、,所以叫做非谓语动词。( 一)动词不定式: 动词不定式由 “to+ 动词原形”构成,如:to 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。 不定式 一般式 完成式 进行式 完成进行式主动 to build to have built to be building to have been building被动 to be build to have been buil
3、d2、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
4、another middle school for the peasants children.我们的计划是给农民子弟再成立一所中学。 (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 t
5、o 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) 。 (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,但动词不定式之前如有疑问词时,就可作介词的宾语,如:Can you
6、 give us some advice on what to do next? (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
7、 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 e
8、arly to read English. 为了强调不定式表示目的的作用,可在不定式前加 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
9、see the liberation of their home town.他们活到亲眼见到了他们家乡的解放。 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. 3、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 for2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
10、 for the harvest. 当作表语用的形容词表示不定式的逻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. 4、疑问词 + 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 swimmin
11、g in this river is a problem. 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:
12、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 sorry to 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 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.非谓语动词(二) 动词-i
13、ng 形式(二)-ing 形式:动词的-ing 形式也是一种非谓语动词。-ing 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、-ing 的形式:-ing 有一般式和完成式。及物动词的-ing 还有主动语态和被动语态,而不及物动词的-ing则没有被动语态。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:及物动词 make 不及物动词 go动词-ing主动语态 被动语态 主动语态一般式 making being made going完成式 having made having been made having gone2、-
14、ing 形式的基本用法。 (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。She likes drawing very m
15、uch.;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:This book is well wor
16、th 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? (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
17、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, he
18、ar, observe, feel, find, 3have, keep 等。 (6)作状语:时间状语:Seeing Tom, I couldnt help thinking 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
19、式的基本用法。主动语态-ing 完成式所表示的动作发生在句中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:Having 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
20、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 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
21、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、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
22、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 very 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
23、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 goi
24、ng on inside. 非谓语动词(三)过去分词( 三)过去分词: 1、过去分词的基本用法:过去分词只有一种形式,也没有主动语态,它所表示的动作是一个被动的或是已完成的动作。过去分词在句中也可用作定语、表语、宾语或状语等成分。过去分词在句中作某种成分时,其逻辑主语一般为该分词所表示的动作的承受者,如: (1)作定语:过去分词作定语时,如果这个分词是一个单词,就位于其修饰的名词之前,如果是分词短语,就位于其修饰的名词之后。被过去分词所修饰的名词,就是该分词的逻辑主语,如:The stolen car was found by the police last week. (2)作表语:过去分词
25、作表语时,表示其逻辑主语所处的状态,其逻辑主语就是句中的主语,如:The glass is broken.这个玻璃杯是破的。 注:过去分词作表语时,和动词的被动语态结构相似,但两者表达的意义不同,如:The glass was broken by my little brother.这个玻璃杯是被我小弟弟打破的。作表语用的过去分词在许多词典中已列为形容词,如:crowded, devoted, discouraged, done, dressed, drunk, experienced, frightened, gone, hurt, interested, killed, known, le
26、arned, lost, pleased, satisfied, shut, surprised, tired, undressed, worried, astonished, broken, completed, covered 等。 (3)作宾语补足语:过去分词作宾语补足语时,句中的宾语就是其逻辑主语,如:When I opened the door, I found the ground covered by fallen leaves. 注:动词 have 后的复合宾语中,宾语补足语如为过去分词,常表示4该分词所表示的动作是由别人来执行的而不是句中主语自己来执行的,如:I had my
27、 bike repaired yesterday. 昨天我(找别人)把我的自行车给修了。 (4)作状语:过去分词作状语时,相当于一个状语从句,该结构的逻辑主语一般都是主句的主语,是过去分词所表示意义的逻辑宾语。为了使作状语的过去分词意义更加明确,常在分词前加 when, if, while, though, as 等连词,如:Seen from the hill/ When seen from the hill, our town looks beautiful.; Given more time/ If given more time, we could have done it bette
28、r.(we 是该结构的逻辑主语,是 give 的逻辑宾语。 ) 独立主格:上述-ing 和过去分词的用法中,-ing 和过去分词在句中均有逻辑主语,但有时它们也能有 自己的独立的主语,这种独立的主语,一般为名词或代词,位于其前之前,和-ing 或过去分词构成独立主格。独立主格在句中一般只作状语用,而-ing 和过去分词作用的形式,则要根据它们所表示的动作和句中谓语动词所表示的时间关系而定。至于独立主格中是使用-ing 或是过去分词,则要根据它们的主语和其所表示的动作的主动被动关系而定,如:The bell ringing, we all stopped talking. 注:The work
29、having been finished, she sat down to have a rest. 独立结构中的 being 或 having been 常可省去,如:The meeting (being) over, all left the room. 作伴随状语的独立结构常可用 with 短语来代替,如:She read the letter, tears rolling down her cheeks./ She read the letter with tears rolling down her cheeks. 2、-ing 形式与过去分词的区别: (1)语态不同:-ing 形式
30、表示主动概念,及物动词的过去分词表示被动概念。an inspiring speech 鼓舞人心的演说;the inspired audience 受鼓舞的听众。 (2)时间关系不同:现在分词所表示的动作一般是正在进行中的动作,而过去分词所表示的动作,往往是已经完成的动作,如:The changing world 正在发生的世界; the changed world 已经起了变化的世界。易错易混点 1疑问词 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
31、is a problem. 2动词不定式的否定式:由 not 动词不定式构成.3v.-ing 形式与动词不定式在句中作主语、表语、宾语时的区别。 v-ing 形式:表示抽象或泛指的动作。 不定式:表示具体某一次的动作。 She likes playing the piano, but she doesnt want to play it today. 4v.-ing 形式与动词不定式在句中作定语的区别。 v-ing 形式:动作与谓语动词所表示的动作同时发生。 不定式:动作发生在谓语动词所表示的动作之后。 eg. The girl writing a letter there can speak
32、 English very well. I have three letters to write. 5v.-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 v.-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
33、 hear her sing in the room. 我听见她在屋里唱过歌。6v.-ing 形式与动词不定式在句中作状语的区别。 v-ing 形式:表示时间、原因、方式或伴随情况。 不定式:作目的或结果状语。 7v.-ing 形式与过去分词的区别: (1)语态不同:v.-ing 形式表示主动概念,及物动词的过去分词表示被动概念。 an inspiring speech 鼓舞人心的演说; the inspired audience 受鼓舞的听众 (2)时间关系不同:现在分词所表示的动作一般是正在进行中的动作,而过去分词所表示 的动作,往往是5已经完成的动作,如: the changing wo
34、rld 正在变化的世界 the changed world 已经变化了的世界 8独立主格结构:有时 v.-ing 和过去分词在句中也有自己的独立的主语,这种独立的主语 一般为名词或代词,和 v.-ing 还有过去分词构成独立主格结构。该结构在句中一般只作状语。 独立主格中是使用 v.-ing 还是过去分词,则要根据它们的主语和其所表示的动作的主动或被 动关系来定,如:The bell ringing, we all stopped talking. 注意: 独立结构中的 being 或 having been 常可省去,如: The meeting_(being)_over, all left
35、 the room. 作伴随状语的独立结构常可用 with 短语来代替, 如: She read the letter, tears rolling down her cheeks. She read the letter with tears rolling down her cheeks.非 谓 语 的 解 题 步 骤 或 思 路(1) 先判断空格部分所需的是主句,从句还是非谓语动词。 独立的句子, 从句或非谓语 独立的句子 加句号,分号或破折号的话,后再加一个独立的句子。 独立的句子, (逗号) 有 and,but, so 等词 加独立的句子。 (2)再根据主句的主语,来判断主动或被动;

37、主语和主句主语不一致,还要 考虑独立主格结构,也就是把非谓语动词的自己的主语加上去: 例如: All flights having been cancelled , they decided to take the train. 其次,把非谓语动词和主句的动词比较,看是否同时发生还是有明显的先后。 (2) 跟在介词,动词或某些形容词的后面固定搭配 只接动词-ing 形式而不接不定式作宾语的动词有: admit 承认 appreciate 感激 avoid 避免 put off 推迟 keep 保持 consider 考虑 delay/ postpone 耽搁 dislike 嫌恶 resist
