非限定动词英语中非限定动词有三种:动词不定式、分词和动名词。
非限定动词在句中能充当谓语的一部分,但不能单独充当谓语,故又称非谓语动词。
它们的形式不随主语的人称和数的变化而变化,但仍具有动词的一般特征,可以带宾语。
一、非谓语动词时态、语态变化形式及其用法当非谓语动词所表示动作发生在谓语动词表示动作之前时,非谓语动词用完成时形式。
例:1)Having finished my homework, I listened to music for relaxation.当非谓语动词所表示动作与谓语动词所表示动作同时发生时,非谓语动词用进行时或一般时形式。
例:2)He pretended to be working hard when his mother entered his room.当非谓语动词所表示动作发生在谓语动词所表示动作之后时,非谓语动词用一般时形式。
例:3)I expect you to write to me.二、非限定动词的句法功能比较动词不定式(或不定式短语)具有名词、形容词和副词的性质,在句中能充当主语、表语、宾语、定语、补语或状语。
动名词(或动名词短语)具有名词形质,在句中常作主语、表语、宾语或定语。
分词(或分词短语)具有形容词和副词的性质,在句中可作表语、定语、补语或状语。
非限定动词的句法功能列表如下:1.动词不定式(短语)、和动名词(短语)作主语的区别1)当主语和表语都是非限定动词形式时,主语和表语的非限定形式要求一致。
例:①To live is to struggle. [正]②To live is struggling. . [误]③Living is to struggle. . [误]④Living is struggling. . [正]2)当主语为非限定动词,而表语不是的时候,不定式和动名词作主语都可以,意义有区别,但区别很小,可忽略。
区别在于:不定式强调动作性,常表示一次性、短暂的动作;而动名词倾向于名词性,常指多次重复的动作。
高中非谓语的三种形式和用法(一)非谓语动词一、定义非谓语动词(Non-Finite Verbs)是指动词形态上不能用作谓语或表语的各种动词,它不能表示完成形式、时态和语态,它包括动名词、不定式、分词和现在分词。
它们都可以做主语、宾语或补足语。
二、分类(1)动名词动名词(Gerund)是动词词尾加 -ing 构成的名词,它是动词的名词化形式,一般能起主语、宾语及补语的作用,作主语时通常用来表示某种动作被一般进行着。
(2)不定式不定式(Infinitive)是由 to 加上动词原形构成,能作主语、宾语及补足语,表示某种未完成的动作或态度。
(3)分词分词(Participle)是现在分词(Present Participle)和过去分词(Past Participle)的统称,它的形态类似形容词,但可作简单句中的状语,也可作定语、表语和宾语补足语,有时也能作主语。
现在分词(Present Participle)的形式结尾常常是-ing,例如 working,它在现在完成时态中往往作定语,表示时间先后次序。
三、用法动名词可以作主语、宾语和补足语,在简单句中可以作主语,如:Studying other culture is quite interesting. 学习其他文化很有趣。
也可以作宾语,如:I like studying other culture. 我喜欢学习其他文化。
还可以作补足语,如:He was seen studying in the library. 他被看到在图书馆里学习。
不定式可以作宾语、宾语补足语及表语,但不能作状语,它可以用来表示时间、条件、原因、让步等,如:He agreed to help me. 他同意帮助我。
We came here to visitthe museum. 我们来这里参观博物馆。
分词可以用作定语、表语、状语、宾语补足语和宾语,用作定语时表示定语所修饰的名词发生的先后顺序,如:A broken cup was found on the ground. 地上发现了一个破杯子。

non-finite verbs 和finite verbs.的区别。
A : 概念上的不同根据动词在分句或句⼦中能否单独做谓语可判定non-finite verbs 和finite verbs.1. non-finite verbs 是动词的⾮谓语形式,不能单独做谓语。
1.1. 动名词eg. Seeing is believing.It is no use sading.1.2. 不定式eg. To see is to believe.Nice to meet you.1.3 现在分词eg. Putting my book on the table.1.4 过去分词eg. When we arrived, we were given printed in the strong wind.Excited by the sale figures, we dicided to go out and have a meal.2.finite verbs 在分句或句⼦中做谓语,它受主语的⼈称和时间的限定。
eg: I am a student. She often writes.You are a student.She is a student.B. non-finite verbs and finite verds 并不是两种不同的动词,⽽是同⼀动词的两种的不同形式。
每⼀个动词都有它⾃⼰的限定形式和⾮限定形式。
eg. I am a student. am是系动词,在句中做谓语。
I am studing grammer. am 是助动词,帮助构成进⾏时态。
I have three sisters. have 是实义动词,⽤做谓语。
I have studied English for 13 years. have 是助动词,帮助构成完成时态。
注意:non-finite verbs 虽然不能单独做谓语,但是在做谓语的限定动词短语中,却少不了non-finite verbs.除了现在⼀般时和过去⼀般时以外,其他时态和语态的谓语都是由限定动词短语担任的。
10.1.1 非限定动词的含义和种类1)非限定动词(non-finite verb)作为动词的非谓语形式,不受主语的人称和数的限制,不能在句中做谓语,这是非限定动词与限定动词(谓语动词)的主要区别。
2)非限定动词没有语法上的主语,但往往有逻辑上的主语。
例 1 Experts hope to find a solution to the problem.专家们希望能找到解决这一问题的方法。
(不定式to find…的逻辑主语是句子主语experts。
)例 2 It would be difficult for the youth to understand this.要让年轻人理解这一点是会很难的。
(不定式的逻辑主语是theyouth)3)非限定动词有三种,即不定式(infinitive),动名词(gerund)和分词(participle)。
分词又有现在分词(present participle)和过去分词(past participle)两种。
10.1.2 非限定动词的性质非限定动词具有双重性质,即动词性质和非动词性质。
1)限定动词的动词性质表现在:非限定动词有时态和语态变化,有肯定与否定形式,可被状语修饰,可带宾语等。
2)非限定动词的非动词性质表现在:不定式和动名词具有名词性质,而分词具有形容词性质。
10.1.3 非限定动词的语法作用由于不定式和动名词具有名词性质,因此可在句中做主语、表语、定语、宾语和补语;另外不定式和介词+ 动名词还可做状语。
而由于分词具有形容词性质,因此可在句中做表语、定语、状语和补语,但不能做主语和宾语。
10.1.4 非限定动词短语及其复合结构由于非限定动词具有动词性质,因此可与表语、宾语、状语等修饰语连用,构成非限定动词短语,即不定式短语,动名词短语和分词短语。
非限定动词短语的逻辑主语可以是句子中的某一成分(如主语或宾语等),如10.1.1中的例1;而其本身也可以带逻辑主语,构成非限定动词复合结构,如10.1.1中的例2。
非谓语动词1、定义:在句子中充当除谓语以外的各种句子成分的动词形式,叫做非谓语动词(the Non-Finite Verbs)。
非谓语动词也是动词的一种,他们有着动词的其他特点,可以充当主语、宾语、状语等。
非谓语动词与谓语动词是相对的概念。
形式功能:动词不定式动词不定式:(to)+ do,具有名词、形容词、副词的特征。
否定式:not + (to) do以do为例,动词不定式的构成如下:1.一般式:不定式的一般式所表示的动作与谓语动词动作同时发生或发生在谓语动词动作之后.例如:It's nice to meet you.很高兴见到你。
He seems to know a lot. 他看起来懂得很多。
We plan to pay a visit. 我们计划去参观。
He wants to be an artist. 他想成为一个艺术家。
The patient asked to be operated on at once. 病人要求马上手术。
The teacher ordered the work to be done. 老师要求完成工作。
2.进行式:不定式的进行式所表示的动作与谓语动词动作同时发生,例如:The boy pretended to be working hard. 男孩假装工作得很努力。
He seems to be reading in his room. 看起来他正在他的房间里面读书。
3.完成式:不定式的完成式表示的动作发生在谓语动词动作之前,例如:I regretted having told a lie. 我后悔我说谎了。
I happened to have seen the film. 我偶然看过这部电影。
He is pleased to have met his friend. 他很高兴能遇上他的朋友。
不定式的句法功能:(1)作主语:To finish the work in ten minutes is very hard. 十分钟之内完成这项工作是很难的。
在英语中,不做句子谓语,而具有谓语外其他语法功能的动词中,叫“非谓语动词”非谓语动词包括:动词不定式(the Infinitive)动名词(the Gerund)现在分词(the Present Participle)过去分词(the Past Participle)Ⅰ。
动词不定式:动词不定式有两种,带“to”和不带“to(动词原型)”,有人称之为“光秃不定式”,在大多数情况下不定式都带to,动词不定式由“to+动词原型”,这里的to是不定式标志,没有词义,不定式具有名词,形容词,或副词的某些语法功能,又有动词的时态和语态。
一:1。
不定式做主语:eg : To over come the problem is very difficult不定式做主语,往往用it做形式主语,真正的主语不定式放置句子后面:eg : It‟s so nice to hear your voice.但是,用不定式做主语的句子中还有一个不定式做表语时,不能用it‟s…to…的句型eg : To teach is to learn.比较“it‟s for sb和it‟s of sb1)for sb句型中的形容词一般为表示事物的特征特点,表示客观形式的形容词,如”easy, hard, difficult, impossible”等2)of sb句型中的形容词一般为表示性格,品德,心智能力,表示主观感情或态度的形容词,如”good, kind, nice, clever, foolish”等3)用介词for或者of后面的逻辑主语做句子的主格,用介词前边的形容词做表语,造这个句子,如果通顺用of,不通则用for2.不定式做表语:不定式可放在be动词后面,形成表语eg : My dream is to be a teacher.3.不定式做宾语1)有些及物动词用不定式做宾语,结构为“动词+不定式”P2892)有些动词除了可以用不定式做宾语,还用些不定式做补语,即“动词+宾语+不定式”结构eg : I like to keep everything tidy.I like you to keep everything tidy.3)有些动词或动词词组可以用“动词+疑问词+不定式”的结构:eg : I want to know how to solve the problem.4)如果不定式(宾语)后面有宾语补足语,则用“ it ”做形式宾语,真正的宾语(不定式)后置,放在宾语补足语4.不定式做补语1)有些动词+宾语+不定式P291eg : Father will not allow us to play on the street.2)有些动词+宾语+不定式的结构,不定式的动词往往是be,不定式一般可以省去eg : We believe him (to be) quilty (adj.)我们相信他是有罪的We know him to be fool. (n.) (to be不能省)3)有些动词可以跟”there + to be的结构eg : We didn‟t expect there to be so many people.You wouldn‟t want there to be another war. 你不至于想让另外一场战争发生吧?5.不定式做定语不定式做宾语,通常要放在被修饰的词后,往往表示未发生的动作。
