1、Four short words sum up what has lifted most successful individuals above the crowd: a little bit more.-author-date非谓语动词口诀(速记重点)非谓语动词包括动词不定式,动词的过去分词和动词的-ing形式三种。这是高考中的热点,其考查量多、面广,几乎是必考的一个知识点。近六年高考复现率达百分之百。纵观试题,其考查重点为动词非谓语形式的作用及功能相同的非谓语动词之间的区别。学生对此知识也“知之半解”,深感头疼。请看下面的方法,将有助于记住不定式及动名词。非谓语动词包括动词不定式,动词的
2、过去分词和动词的-ing形式三种。这是高考中的热点,其考查量多、面广,几乎是必考的一个知识点。近六年高考复现率达百分之百。纵观试题,其考查重点为动词非谓语形式的作用及功能相同的非谓语动词之间的区别。学生对此知识也“知之半解”,深感头疼。请看下面的方法,将有助于记住不定式及动名词。1、动词的不定式不定式有标记,to与动词连一起。没有人称数变化,动词特点它具备。主宾定状表补语,唯独作谓不可以。not 加上不定式,否定结构要牢记。疑问词与不定式,构成短语有意义。仔细推敲多思考,准确判断有依据。 解析:“to+动词原形”是它的基本构成形式,即不定式的标记。它没有人称和数的变化,不管主语是任何人称,单数
3、还是复数,动词不定式都没有变化。但它仍保留动词的特点,可以有自己的宾语或状语。它具有名词、形容词和副词三大特点,所以,它在句中可以作主语、宾语、定语、表语、状语和宾补。“not +动词不定式”是它的否定形式,不要受其他否定式的影响,要记住规律。疑问代词what, who, whom, which和疑问副词where, when, why , how加上不定式在句中可以做主语,宾语、表语、状语。通过以上分析,只要仔细研究,把不定式的功能用法搞清楚,在应用时就能作出准确的判断。2、动名词:哪些动词后面只能接动名词,下面的顺口溜有助于记忆。喜欢、考虑不可免(enjoy, consider, esca
4、pe, avoid)停止,放弃太冒险(stop, give up , risk)反对想象莫推延(mine, imagine, delay, put off)要求完成是期望(require, finish, look forward to.)建议继续勤*练(suggest, go on, practise)不禁原谅要坚持(cant help, excuse , insist on)继续注意使成功(keep on, mind, succeed in)1. Everyone in our class was working hard and doing what we could _ a good
5、college.A. enterB. to enterC. enteringD. entered【陷阱】容易误选A。有的同学一看到空格前的情态动词 could 就断定此处应填动词原形 enter。【分析】其实正确答案应是B。此句为省略句,即在 could 后省略了动词 do,若把句子补完整应为Everyone in our class was working hard and doing what we could do to enter a good college。即句中的不定式短语(to enter a good college)是用作目的状语的,而不是与情态动词(could)一起构成谓
6、语。请再看类似例句:(1) They did what they could to comfort her. 他们尽量安慰她。(2) They did everything they could to save her life. 他们尽一切力量拯救她的性命。(3) He studies as hard as he could to catch up with his classmates. 他拼命学习以便赶上他的同学。值得指出的是,这也并不是说今后只要遇到类似结构的题就一定选带to不定式。请看以下试题:(4) He ran as fast as he could _ to catch the
7、 early bus.A. to hopeB. hopeC. hopingD. hoped此题的答案是 C不是A,其中的现在分词短语 hoping to catch the early bus 用作伴随状语。(5) He spent every minute he could _ spoken English.A. practiseB. to practiseC. practisingD. practised此题答案选 C,这与前面动词 spent 的搭配有关,即 spend . (in) doing sth。若将此句补充完整,即为 He spent every minute he could
8、 spend in practising spoken English.(6) Before going abroad he devoted all he could _ his oral English.A. improveB. to improveC. improvingD. to improving此题答案选D,注意两点:一是 devote . to . 是固定搭配,意为把.贡献给.;二是其中的 to 是介词,不是不定式符号,后接动词时要用动名词。2. He knows nothing about it, so he cant help _ any of your work.A. doi
9、ngB. to doC. being doingD. to be done【陷阱】容易误选A,根据 cant help doing sth 这一结构推出。【分析】其实答案应选B。比较以下结构:cant help to do sth = 不能帮助做某事cant help doing sth = 禁不住做某事,情不自禁地做某事又如下面一题,答案也是 B:She cant help _ the house because shes busy making a cake.A cleaningB. to cleanC. cleanedD. being cleaned再请看以下试题:While shopp
10、ing, people sometimes cant help _ into buying something they dont really need.A. to persuadeB. persuadingC. being persuadedD. be persuaded此题应选C,句中的 cant help 意为禁不住(注意根据句意用被动形式)。3. All her time _ experiments, she has no time for films.A. devoted to do B. devoted to doingC. devoting to doing D. is dev
11、oted to doing【陷阱】几个干扰项均有可能误选。【分析】此题最佳答案为B。现分析如下:(1) devote 意为致力于,献身于,主要用 devote.to.或be devoted to,其中的to 是介词,不是不定式符号,故后接动词时要用动名词,不用不定式。(2) 选A错误:若将 do 改为 doing 则可以。(3) 选B正确:all her time devoted to doing experiments为独立主格结构,用作状语。(4) 选C错误:因为all her time 与 devote 为被动关系,故应将devoting改为devoted。(5) 选D错误:若单独看 A
12、ll her time is devoted to doing experiments,此句并没有错,但问题是逗号前后两个简单句没有必要的连接方式,所以从整体上看仍不对,假若在后一句的句首加上and或so,则可选D,或将D将中的is 改为 being也可选它。请做以下类似题(答案均选A):(1) All the preparations for the project _, were ready to start.A. completed B. have been completedC. had been completed D. been completed(2) Such _ the ca
13、se, I couldnt help but_ him.A. being, support B. was, supportC. has been, supporting D. is, to support比较以下各题,答案选B,因为句中使用了并列连词and:(1) All the preparations for the project _, and were ready to start.A. completed B. have been completedC. had been completed D. been completed(2) Such _ the case, I couldn
14、t help but_ him.A. being, support B. was, supportC. has been, supporting D. is, to support4. The purpose of new technologies is to make life easier, _ it more difficult.A. not make B. not to makeC. not making D. do not make【陷阱】容易误选C,受题干中的逗号的影响,认为是现在分词表结果的用法。【分析】其实答案应选B,句中的逗号相当于连词 and 或 but,not to ma
15、ke it more difficult 是对逗号前的不定式 to make life easier 的补充说明。此句的意思是新技术的目的是为了使生活变得更容易,而不是使生活变得更困难。两个不定式同时用以说明句子主语 purpose 的内容。请做以下类似试题(答案选B):The purpose of the scheme is not to help the employers but _ work for young people.A. provide B. to provideC. providing D. provided5. The murderer was brought in, w
16、ith his hands _ behind his back.A. to be tied B. being tiedC. tied D. having tied【陷阱】容易误选B。【分析】最佳答案为C。从意义上看,hands 与 tie 的关系应属被动关系,故排除D。在A、B、C三个选项中,选项A比较容易排除,因为不定式表示将来意义,在此与语境不符。现将B和C作一比较:B为现在分词的被动式,它表示两层意义,一是表被动,二是表进行,也就是说 his hands being tied 的实际意思是他的手正在被捆住,这显然与语境不符。而C为过去分词,它也表示两层意义,一是表被动,二是表示动词的完成
17、或完成后的状态,此句中的 with his hands tied behind his back 可视为手被捆在背后的一种状态。由此可知最佳答案为C。请看下面一题:Anyone _ trying to take knives on heard flights would be caught by the police.A. finds B. foundC. being found D. will find答案选B而不选C,其中的过去分词表示被动和完成。比较下面两题,最佳答案是D不是A,现在分词的被动式表示被动和进行:(1) The court hears about 120 cases a y
18、ear; visitors are welcome to see a case _.A. argued B. to be arguedC. to be arguing D. being argued(2) The silence of the library was sometimes broken by an occasional cough or by the sound of pages _.A. turned B. having turnedC. to be turned D. being turned6. Remind me _ the medicine tomorrow.A. of
19、 taking B. takingC. to take D. take【陷阱】容易误选A。受 remind sb of (doing) sth 这一常用结构的影响。【分析】最佳答案为C。比较以下三个结构:remind sb of about sth = 使某人想起某事remind sb of doing sth = 提醒某人做过某事(暗示动作已发生)remind sb to do sth = 提醒某人去做某事(暗示动作尚未发生)请看两个例句:I reminded him of his promise. 我提醒他做过的诺言。My wife reminded me of seeing that f
20、ilm. 我妻子提醒我曾经看过那部电影。Can you remind me to phone her tomorrow? 你明天能否提醒我给她打电话?7. Once your business becomes international, _ constantly will be part of your life.A. you fly B. your flightC. flight D. flying【陷阱】几个干扰项均有可能误选。【分析】最佳答案为D。由于空格后出现了constantly这一副词,这就说明不能选B或C,因为B、C均为名词,不能受副词 constantly 的修饰。A和D均是
21、可能的,因为其中有动词 fly。但若选A,you fly 是一个主谓结构,与其后的谓语 will be 相冲突,所以只能选D,即动名词flying在此用作主语。8. Not only should you get used _ under difficult conditions but you also you pay more attention _ your work well.A. to work, to do B. to working, to doingC. to work, to doing D. to working, to do【陷阱】容易误选A,认为两个空白处均应填不定式。
22、【分析】正确答案为B,因为 get used to与pay attention to 这两个结构中的to均为介词,不是不定式符号,故后接动词时要用动名词,不能动词原形。类似地,以下各结构中的 to 也是介词,不是不定式符号,后接动词时也应用动名词,而不是动词原形:look forward to doing sth 盼望做某事be opposed to doing sth 反对做某事object to doing sth反对做某事stick to doing sth 坚持做某事get down to doing sth 开始做某事take to doing sth 喜欢上做某事admit to
