1、,非谓语动词的用法区别,非谓语动词,动名词,分词,现在分词,过去分词,动词不定式,1.谓语动词：,概述：,2.非谓语动词：,在句子中担任谓语的动词,是动词的特殊形式，在句中可以作除谓语外的所有成分,一个句子当中，已经存在一个主句（谓语动词）,又没有连词的情况下,还有别的动词出现时。例如:,非谓语动词使用条件：,She got off the bus,leaving her handbag on her seat.（没有连词）She got off the bus,but left her handbag on her seat.（有连词）,非谓语动词的用法区别,动词不定式与动名词动词不定式与分

2、词动名词与现在分词现在分词与过去分词其它情况,一、动词不定式与动名词,从结构上看，两者不同之处有：动名词前可用介词，它还可以被名词所有格（或代词）修饰；不定式前通常不用介词，更不能被名词所有格（或代词）修饰。在实际应用中，下列各点值得注意：,1、作主语或表语时,一般说来，在表示比较抽象的一般行为时多用动名词；在表示具体的动作，特别是将来的动作时，多用不定式。,Smoking is not allowed here.(表习惯、爱好、或抽象的动作、经常做的事情。)To smoke so much is not good for you.(表具体的、一次性动作、要做的事情。)Their job is

3、 building houses.(抽象、经常的动作)Their work is to build another bridge across the river.(具体、将要做的动作),2、作宾语时,1)动名词可作动词和介词的宾语2)动词不定式一般作动词的宾语，疑问词to do 可作介词的宾语。,They preferred walking to school to cycling.They preferred to stay at home rather than go out in such hot weather.Our English teacher often gives us s

4、ome advice on how to learn English.,1、作动词宾语时，两种结构在意义上有时差别不大，这样的动词有：like,hate,prefer,begin,start,continue,intend,attempt,propose,deserve,need,cant bear,等。,Do you like playing(to play)chess?When did you begin learning(to learn)English?Your suit needs ironing(to be ironed).,动词不定式与动名词,注意,在like,hate,pref

5、er 等动词之后，如果表示一般性、习惯性的动作，多用动名词作宾语；如指特定的或某次行动，则用不定式更多一些。,I like reading books of this kind,but I dont like to read that book.She prefer walking to cycling.I prefer to stay at home today.,2、作动词宾语时，两种结构在意义上有时差别很大，这样的动词有：remember,forget,regret,stop,mean,try,等。remember/forget/regret+v-ing 表已经发生的动作，remembe

6、r/forget/regret+to+v-原形 表动作还没有发生。mean doing 意思是；意味着mean to do 意欲，打算要做stop to do 停下来去干另一件事请stop doing 停止正在做的动作try doing 试着做、尝试做try to do sth.试图做、努力做,动词不定式与动名词,regret doing sth.对做过的事表示遗憾、后悔regret to do sth.对要做某事表示遗憾,3、在动词want,require,need,等后动词不定式（短语）作宾语时，用人作主语；动名词作宾语时（=to be done)，用物作主语。,Someone needs

7、 to see you,sir.The wall needs repairing(=to be repaired).I want to go to the barbers because my hair wants cutting(=to be cut).,动词不定式与动名词,4、动名词作定语表示所修饰名词的用途，常常放在所修饰名词之前；而动词不定式作定语表未发生的动作，常常放在所修饰名词之后。,We have various kinds of clothes for you to choose from.His attempt to solve the difficult problem f

8、ailed again.These passages may be used as listening materials.Mr Wang suffers from insomnia,he has to take a sleeping tablets before going to bed.,动词不定式与动名词,二、动词不定式与分词,一般说来，动词不定式表主动、将来；现在分词表主动、进行；过去分词表被动、完成。,三、动名词与现在分词,动名词与现在分词同形（v-ing），但是，两者有各自的语法名称和作用：1）当v-ing形式在句中作主语、宾语、表语、定语时，被称为动名词。2）当v-ing形式在句

9、中作状语、宾语补足语、表语、定语时，被称为现在分词。,可见，二者都可以作表语和定语。,（一）作表语时的区别,1、现在分词作表语表示主语的特征或属性；2、动名词作表语表示主语的内容、功能等。,The news is exciting.(现在分词表特征）2.Her work is nursing children.（动名词表内容）3.Her favorite job is teaching English.（动名词表内容）4.The story sounds interesting.(现在分词表特征）,动名词与现在分词,（二）作定语时的区别,1、动名词作定语表示所修饰名词的作用、用途等，常常放在所

10、修饰名词之前；2、现在分词作定语表示它所修饰的名词的动作，被修饰名词与现在分词在逻辑上是主谓关系，说明所修饰的词、所代表的人或物所做的动作或特征；单个分词作定语，位于所修饰的名词之前，分词短语作定语放在所修饰的名词之后。,1.flying fish=fish which can fly 飞鱼（现在分词）2.flying suit=suit for flying 飞行衣（动名词）,动名词与现在分词,四、现在分词与过去分词,两者之间的区别主要体现在时态和语态上：（1）在时态上：现在分词表示正在进行，而过去分词表示已经完成。（2）在语态上：现在分词表示主动；而过去分词表示被动。总之，现在分词表主动、

11、进行；过去分词表被动、完成。在句法功能上它们都可以作定语、表语、状语和宾补，它们的具体区别如下：,The meeting held last week is very important.Tell the children playing there not to make so much noise.They lived in a room facing(=that faced)the south.I hate to see letters written in pencil.,1、现在分词作定语表示正在进行的动作，或表示经常性的动作,或现在(或当时)的状态；2、过去分词作定语时，过去分词所

12、表示的动作可以在谓语所表示的动作之前发生，也可以是没有一定的时间性。,1、作定语时,现在分词与过去分词,2、作表语时,现在分词多表示主语所具有的特征或属性；过去分词多表示主语所处的状态。现在分词表示“令人的”，过去分词表示“感到”.常见的分词有：amazed/amazing,excited/exciting,bored/boring,annoyed/annoying,interested/interesting,pleased/pleasing,tired/tiring,surprised/surprising,worried/worrying,satisfied/satisfying,amu

13、sed/amusing 例：,The news was exciting.He appeared satisfied with my answer.,现在分词与过去分词,3、作宾语补足语时,现在分词与句子的宾语是主动关系，它所表示的动作往往正在进行；过去分词与句子的宾语是被动关系，它所表示的动作往往已经完成。,I found them painting the windows.（现在分词表主动、进行）I found the windows painted.（过去分词表被动、完成）,现在分词与过去分词,其它注意事项,不定式动词在介词but，except，besides后面时，如果这些介词之前有行

14、为动词do的各种形式，那么，这些介词后的不定式不带to，否则要带to。,She could do nothing but cry,What do you like to do besides swim?,I have no choice but to go,作定语,不定式作定语时，通常放在被修饰的名词或代词之后。不定式常和它所修饰的词有动宾关系。如：,Ihavealotofworktodo.Herearesomebooksforyoutoread.Shewasthefirstpersontothinkoftheidea.,(1)作主语,不定式做主语时，可以直接放在谓语动词之前。,To see

15、is to believe,Not to get there in time is your fault.,注：常用it做形式主语，将to do放在位于之后，使句子保持平衡。,句型1：It+谓语+to do,It takes us an hour _ get there by bus.,句型2：Its+n.+to do,Its our duty _ help the poor.,It is a great enjoyment _ spend our holiday in the mountains,不定式其他用法,这个句型还要注意对称原则,句型3：It is adj.for/of sb.to

17、are very kind to give me some help.,you are impolite to speak to the teacher like that.,注意：1.如果不定式是不及物的，它后面就应有必要的介词。如：,He is looking for a room to live in,Please give me a knife to cut with,2.不定式作状语,表目的 不定式作目的状语时，其动作发生在谓语动词之后，一般放在句子后部。但如要表示强调，也可以位于句首，前面可加in order,其否定必须用in order not+不定式，或so as not 不定

18、式。in order to 引出的不定式可置于句首或句中，so as not不定式不能放在句首，只能放在句中。He stopped to have a rest.他停下来休息。（目的）To search for gold,many people went to California.为了寻找金子，许多人去了加利福尼亚。（目的）He is so careless as to forget his pen.她太粗心了，以至于把钢笔忘了带。,If time permit,lets finish the following exercises.,Exercises,exercises,Girls,do
