1、1专题 09 非谓语动词【2019 年高考考纲解读】近三年高考主要考查非谓语动词的作用和形式。在作用方面主要考查作宾语时用不定式还是动名词;作宾语、状语、补语时用不定式还是分词;它们作某一成分时的特殊情况及特殊结构。在形式方面主要考查用一般式还是完成式、主动式还是被动式、现在分词还是过去分词。【重点、难点剖析】一、非谓语动词作状语1不定式作状语不定式作状语通常表示:(1)原因(多用在某些表示喜、怒、哀、乐等的形容词后);(2)目的(可用 so as to/in order to 替换,但 so as to 一般不可置于句首);(3)结果(常表出乎意料的结果,常为 only to do)。We
2、were very excited to hear the news.(原因)To get there on time I got up very early.(目的)He rushed to school only to find there was nobody there.(结果)2现在分词与过去分词作状语的区别(1)现在分词作状语时,现在分词所表示的动作与句子主语之间构成逻辑上的主动关系。Not knowing what to do,he went to his parents for help.由于不知怎么办才好,他去找他父母帮忙。(2)过去分词作状语时,过去分词所表示的动作与句子主
3、语之间构成逻辑上的被动关系。Given more attention,the trees could have grown better.如果对这些树多关心一些,它们本来会长得更好。(3)部分过去分词来源于系表结构,作状语时不表示被动关系,其前不用 being。这样的过去分词及短语常见的有:seated(坐着的)、hidden(躲着)、stationed(驻扎 )、lost/absorbed in(沉溺于)、born in(出身于)、dressed in(穿着)、tired of(厌烦了)等。Lost/Absorbed in deep thought,he didnt hear the sou
4、nd.3独立主格结构作状语如果分词作状语的逻辑主语不是句子的主语,须在分词前面加上它自己的主语,这种结构叫独立主格结构,其作用相当于状语从句;有时也用 with 复合结构(with 宾语宾语补足语)作状语。(1)名词/主格代词现在分词2名词/主格代词与现在分词之间是主谓关系。The girl staring at him(As the girl stared at him),he didnt know what to say.女孩两眼望着他,他不知道说什么好。(2)名词/主格代词过去分词名词/主格代词与过去分词之间是动宾关系。The problems solved(As the problem
5、s were solved),the quality has been improved.随着问题的解决,质量已经提高了。(3)名词/主格代词不定式名词/主格代词与不定式之间是主谓关系,且强调的是一次具体性的动作。He is going to make a model plane,some old parts to help.借助于一些旧零件,他要做一个飞机模型。(4)with 复合结构(with宾语宾语补足语)作状语,是用现在分词、过去分词还是动词不定式作宾语补足语,关键是看宾语和宾语补足语之间的关系。With time passing by(time 和 pass 之间为主动关系),he
6、almost forgot everything in the past.随着时间的流逝,他几乎忘记了过去所有的事情。He sat on the chair,with his hands tied(hands 和 tie 之间为被动关系)behind his back.他坐在椅子上,双手在背后捆着。 二、非谓语动词作主语、表语、宾语1非谓语动词作主语(1)Laughing helps your body stay healthy and can even help you fight pain.(动名词作主语)(2)To see is to believe.(不定式作主语)(3)It is i
7、mportant to respect people.(不定式短语作主语,it 作形式主语)(4)It is no use crying over spilt milk.(动名词短语作主语,it 作形式主语)2非谓语动词作表语(1)动名词作表语时,说明主语的性质,回答 what 引导的问句。(2)不定式作表语时,说明主语尚未发生的动作或表示将来的动作。3非谓语动词作宾语非谓语动词作宾语的主要是不定式和动名词(1)afford,agree,choose,determine,expect,decide,learn ,offer,manage,hope,want,wish,pr3omise,refu
8、se,fail,pretend,happen 等动词后跟不定式作宾语。(2)appreciate,avoid,bear,consider,dislike,delay,enjoy ,escape,finish,hate,imagine,keep,mind,miss,practise,postpone,resist,risk,stand ,suggest 等动词后跟动名词作宾语。(3)以下动词后接不定式和动名词作宾语意义不同。动词 接动名词作宾语 接不定式作宾语remember 记得曾做过某事 记得要做某事forget 忘记曾做过某事 忘记要做某事try 尝试做某事 努力做某事regret 对做过
9、的事表示后悔 对要做的事表示遗憾mean 意味着做某事 企图(打算)做某事cant help 禁不住做某事 不能帮助做某事go on 继续做未完成的事做完一件事后,接着做另一件事stop 中断正在做的事中断正在做的事,去做别的事【特别提醒】1动名词作宾语时,可以带逻辑主语。此时,逻辑主语可以是物主代词、人称代词的宾格或所有格。Do you mind my/me reading your paper?你介意我看你的考卷吗?2作宾语的动名词和不定式除了一般式和主动式,还有完成式、被动式。 完成式表示该动作比谓语动作先发生。否定式在 doing/to do 前加 not。(1)I regret no
10、t having taken her advice.(not 须放在 having 前)我感到遗憾,没有听从她的建议。(2)They couldnt stand being treated like that.他们不能忍受被那样对待。(3)He decided to help me but I pretended to have finished my job.他决定帮我,但我假装已经完成工作了。4三、非谓语动词作定语1不定式作定语表未来的动作且后置,它与所修饰的名词或不定式代词存在主谓、动宾或同位关系。You are the third one to enter the room.(主谓关系
11、)I have something important to say.(动宾关系)He has no opportunity to go abroad.(同位关系)2动名词作定语多前置,表示所修饰的事物的性能和用途。a reading room( a room for reading)3现在分词作定语表主动和进行,可转换为定语从句。The question being discussed (which is being discussed) now is important.4过去分词作定语表被动和完成,也可转换为定语从句。The question discussed(which was di
12、scussed) yesterday is important.四、非谓语动词作宾语补足语1advise/allow/ask/beg/expect/encourage/force/get/invite/order/permit/persuade/tell/warn/wish 等动词后面常用不定式作补语。如:Tell the children not to play on the street.The police warned us not to go out at night.2make/let/have 等使役动词后面用不带 to 的不定式作补语,但在被动句中则使用带 to 的不定式。如:
13、They make the students do too much homework every day.The students are made to do too much homework every day.3感官动词后面可用不带 to 的不定式或分词作补语。从时间上看,不定式表示发生或完成;现在分词强调正在进行;过去分词表示完成。从逻辑关系上看,不定式和现在分词与宾语之间存在着主谓关系;过去分词与宾语之间存在着动宾关系。如:I saw him cross the street.我看到他穿过了大街。I saw him crossing the street.我看到他正在穿过大街。I
14、 saw him surrounded by a group of students.5我看到一群学生围着他。五、非谓语动词的否定式、进行式、完成式和被动式1非谓语动词的否定式均是在前面加 not。He pretended not to see me.I regret not following his advice.Not having tried his best,he failed in the exam.2不定式的进行式、完成式和被动式。当谓语动词表示的动作(情况)发生时,不定式动作正在进行,不定式要用进行式。The boy pretended to be working hard.当
15、不定式的动作在谓语动作发生时,不定式要用完成式。I happened to have seen the film.当不定式的逻辑主语为不定式动作的承受者时,不定式要用被动式。The patient asked to be operated on at once.3动名词的完成式、被动式、完成被动式和带有逻辑主语的复合结构。We remembered having seen the film.He came to the party without being invited.He forgot having been taken to Guangzhou when he was five ye
16、ars old.His not knowing English troubled him a lot.4现在分词的完成式和被动式。当现在分词的动作早于谓语动作发生时,现在分词要用完成式。Having done his homework,he played basketball.当现在分词的逻辑主语为其动作的承受者时,现在分词要用被动式。The problem being discussed is very important.Having been told many times,the naughty boy made the same mistake.【题型示例】题型一、辨别谓语与非谓语动

18、的家人对你的决定的看法。分析句子结构可知,before 引导的是时间状语从句,其后是主句,主句中没有出现主语,说明这是一个祈使句,应用动词原形 consider。【举一反三】Let those in need _(understand) that we will go all out to help them.【答案】understand 【变式探究】_ it with me should be a good choice.Trust me!

21、t and fat than they need in their diet.【解析】考查动词ing 作介词宾语。在介词 about,before,after,for,with,by 等之后作宾语应该用动词ing 形式,故用 eating。【答案】eating【变式探究】(2017全国卷)This included digging up the road, _(lay) the track and then building a strong roof over the top.【答案】laying【变式探究】(2016新课标,67)My ambassadorial duties will i

23、wo research findings will be one of the worst mistakes you make. 立意与点拨:设空处位于句首,考虑句中可能缺少主语或状语,再分析句子成分,句中已有谓语动词will be,句中缺少的是主语,再根据句意可知应用动名词形式。 答案:Ignoring 句意为:忽视这两种研究结果的差异将是你所犯的最严重错误之一。分析句子结构可知,句子的谓语部分是 will be,one of the worst mistakes 是表语,you make 是省略关系代词的定语从句,修饰 mistakes。很显然,_ the difference betwe
