非谓语动词是高中英语教学的重点和难点，也是历届高考的重点项目。

命题热点多是借助于基本概念，在语境中考查常用动词的各种非谓语形式以及个性动词后的非谓语形式。

有时也涉及非谓语动词逻辑主语的一致性问题以及独立主格结构中非谓语的各种变化。

其考点主要包括：1．考查对谓语动词与非谓语动词的识别，要求明确句子的结构和意义，掌握非谓语动词的基本用法。

2．考查不定式和动名词作宾语的区别，要求掌握一些常见动词后面所接宾语的形式。

3．考查非谓语动词作定语、状语、补语时的区别，尤其是不定式、现在分词短语、过去分词短语所表示的不同时间、逻辑关系和意义。

现在分词和不定式作结果状语时的区别应引起足够重视。

4．考查非谓语动词的否定式、完成式、被动式及复合结构，要求掌握其构成形式、所表示的时间以及逻辑关系。

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)。

①We w ere very excited to hear the news.(原因)②To get there on time I got up very early.(目的)③He 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。

2019高考英语：二轮专项学案（02）（练习题配解析或解析）专题探究专题探究：专题详解：主要考查的知识点：时间、目的、条件、原因、地点和让步状语从句。

重点复习：时间状语从句，尤其是as，since，while，when，before。

until等连接词。

when，where引导的状语从句和定语从句的区别、让步状语从句的倒装与非谓语动词作状语的区别和转化。

考题(典型例题)Afterthewar,anewschoolbuildingwassetuptherehadoncebeenatheatre.A.thatB.whereC.whatD.who考题点拨：答案为B。

这是where引导的状语从句，不能将其视为定语从句，因为没有先行词，故答案为B。

考题类型回顾1测试考点7(典型例题分)ThechairmanthoughtnecessarytoinviteProfessorSmithtospeakatthemeeting.A.thatB.itC.thisD.him1、B点拨：it作形式宾语，真正的宾语是toinviteProfessorSmithtospeakatthemeeting。

回顾2测试专题探究(典型例题分)Don'tleavethesharpknifeourlittleSanecangetit.A.inwhichB.towhichC.thatD.where2、D点拨：这是where引导的状语从句，不能将其视为定语从句，因为、没有先行词。

回顾3测试专题探究(典型例题)Wewereswim-minginthelakesuddenlythestormstarted.A.whenB.whileC.untilD.before3、A点拨：when引导的状语从句，表示“就在这时或那时”。

强化训练[备考1]测试考点1Onlybyscienceandtechnologycanwemakeourcountrystronger.A.relyonB.relyingonC.dependonD.depending1、B点拨：by是介词，后接名词或动名词，可排除A、C项，D项搭配不对。

（英语）高考英语非谓语动词练习题及答案含解析一、单项选择非谓语动词1．(天津) __________ for two days, Steve managed to finish his report on schedule.A．To work B．WorkedC．To be working D．Having worked【答案】D【解析】试题分析：句意：工作了两天，Steve成功的按时完成了他的报告。

句中的逻辑主语为Steve，与work之间为主动关系，故用现在分词，这里用having worked，表示动作的先后性。

故选D。

【考点定位】考查非谓语动词。

2．（天津）I didn't mean ___________anything but the ice cream looked so good that I couldn’t help_______ it.A．to eat；to try B．eating；tryingC．eating；to try D．to eat； trying【答案】D【解析】考查短语固定搭配。

句意：我不打算吃任何东西，但冰淇淋看起来如此的好以至于我忍不住的要试一试。

固定短语短语mean to do（打算做），couldn’t help doing忍不住做。

故选D。

点睛：本题考查动词短语固定搭配。

同学在平时学习中要多把握动词不同搭配的不同含义，本题需要区分“mean to do打算做”与“mean doing意味着做”和“can’t help to do sth.不能帮助做”与“couldn’t help doing忍不住做”之间的含义。

3．Premier Li Keqiang delivered a speech at the conference, _________ university graduates to start their own business.A．encouraging B．to encourageC．having encouraged D．encouraged【答案】A【解析】非谓语动词结构作非限定的后置定语，修饰先行词演说（“a speech”）。

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)。

非谓语动词在英语语法中占有特殊且重要的位置。

非谓语动词形式多样，应用广泛，且在句中起着很活跃的作用，也是语法项目中的重点和难点，学好非谓语动词，才能正确进行口语和书面的交流。

动词不定式、过去分词及v-ing形式在句中均不能作谓语用，所以叫做非谓语动词。

二. 教学重难点掌握非谓语所能够充当的句子成分（一）非谓语的分类以及各自在句子中所能充当的成分。

非谓语分为不定式，动名词，现在分词和过去分词。

（动名词和现在分词形式相同）以下表格表示的是它们各自所能充当的成分：（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。

2、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：（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：（2）作表语：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 another middle school for the peasants’ c hildren.我们的计划是给农民子弟再成立一所中学。

高考英语非谓语动词试题( 有答案和分析 ) 含分析一、单项选择非谓语动词1．Today there are more airplanes____ more people than ever before in the skies.A． carry B．carryingC． carried D． to be carrying【答案】B【分析】试题剖析：观察此刻分词作定语。

句意：此刻比从前有有更多的飞机运送乘客。

此处airplane 和 carrying 之间是主动关系，故用此刻分词作定语。

应选B。

考点：观察此刻分词作定语【名师点睛】非谓语动词的做题步骤1、判断能否用非谓语形式。

方法：看看句子中能否已有了谓语动词了;2、找非谓语动词的逻辑主语。

方法：非谓语动词的逻辑主语一般是句子的主语。

3、判断主被动关系。

方法：非谓语动词与其逻辑主语的主动仍是被动关系。

4、判断时间关系。

方法：剖析句子，看看非谓语动词所表示的动作发生在谓语动作从前、以后仍是同时。

从前常用done;以后常用to do;同经常用doing. 从本题来看主句的主语airplanes与动词carry组成逻辑上的主动关系，所以用v.-ing 形式作定语。

2．______ to as much English as possible is a good way to learn English well.A． Exposed B． Being exposed C． Having exposed D． To expose 【答案】 B【分析】试题剖析：句意：尽可能多的接触英语是学好英语的很好的方法。

这里主语，应当用动名词，并且be exposed to 暴“露于，接触”，所以选考点：观察动名词做主语B。

is 是谓语，前方是3．John received an invitation to dinner, and with his work ______，he gladly accepted it. A． finished B．finishingC． having finished D． was finished【答案】 A【分析】试题剖析：句意John 接到一张宴会的邀请，他的工作已经达成，他快乐地接受了。

2019高考英语：（04）二轮语法学案（略）（练习题配解析或解析）省略本单元的语法重点是省略，在英语中，为了避免重复，句子中的某些部分经常省略，这样就给同学们理解增加了困难。

在近几年的高考中，省略现象十分常见，为帮助同学们更好地掌握这部分语言现象，现将省略现象归纳如下：1、并列句中某些相同成分的省略。

eg：2、在when，whilE、If,asIf，though(although)。

as、until、once，whether，unless，wherE、等连词连接的状语从句中，常省略跟主句相同的主语和be动词。

eg：When(wateris)pure，wateriscolorlessliquiD、水纯净时，是无色的液体。

When(Iam)introubleIalwaysturntoherforhelp、我有困难时总是找她帮忙。

Errors，ifany，shouldbecorrecteD、如果有什么错误，就应当改正。

(if后省略了thereare)Woodgivesmuchsmokewhile(woodis)burning、木头燃烧时,它冒出很多烟。

Theletteristobelefthereuntil(itis)calledfor、这封信留在这里待领。

Henrylookedaboutasif_(hewere)insearchofsomething、亨利环视四周，似乎在寻找什么。

Shestudiesveryhardthough(sheis)stillratherweak、她尽管体弱，但学习十分努力。

3、当见到“when(if，where，wherever，whenever，assoonas，asfastas，than等)+possi —ble/necessary等”时，可理解为电间省略了、itis(或itwas)。

eg：Answerthesequestions，if(itis)possiblewithoutreferringtothebook、如果有可能，请不看书回答这些问题。

【专题六】非谓语动词【考情分析】非谓语动词包括不定式、v-ing形式和过去分词，是高中英语学习的难点，也是高考考查的重点。

高中英语非谓语动词十个重要考点：1.考查不定式、现在分词与过去分词的基本区别2.考查非谓语动词的主动式与被动式3.考查非谓语动词完成式的用法4.考查非谓语动词用作伴随状语5.考查非谓语动词用作目的状语6.考查非谓语动词用作结果状语7.考查非谓语动词用作宾语补足语8.考查非谓语动词的逻辑主语问题9.考查非谓语动词用作主语的问题10.考查“(be+)过去分词+介词”结构【知识归纳】考点一：非谓语动词的基本用法1.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。

2.现在分词-ing形式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2、主动语态-ing完成式的基本用法。

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.3、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.4、被动语态-ing完成式的基本用法。

2019高考英语：（09）二轮语法学案（非谓语动词）（练习题配解析或解析）本单元的语法是复习非谓语动词，主要复习动词不定式和动名词的被动语态。

(一)动词不定式的被动语态1、当不定式所表示的动作与其逻辑上的主语(句子中的某一名词或代词)有动宾关系时，用被动式。

eg：ItisanhonourformetobeaskedtospeakherE、(“我”是“被邀请的”)承蒙邀请到此讲话，深感荣幸。

Thedateisexpectedtobeannouncedsoon、(“日期”“被宣布”)预计日期会很快被宣布。

但有时，不定式的逻辑主语在句子中不出现，只要在意义上是被动的，就用被动式。

eg：To。

beattackedbytheenemyisagoodthing，notabadthing、受到敌人的攻击是件好事、而不是坏事。

2、在有些情况下不定式的被动意义用主动形式表示。

(1)当不定式与其逻辑上的主语有动宾关系，而同时与另一名词(代词)又有逻辑上的主谓关系时。

eg：GivehimsomebookstoteaD、给他些书读。

(“read”与“books”为动宾关系，而与“him”为主谓关系)I’llshowyourightpathtotakE、(“take”与“path”为动宾关系，而与“you“为主谓关系)(2)但如果只存在动宾关系，而与其他名词(代词)无逻辑上的主谓关系时，就仍用被动式。

eg：AllthepeopleinthecitywerenoWtalkingaboutthewonderfulclothwhichtheEmperorhadorde redtobewovenforsomuchmoney、对于国王定制的漂亮衣服花了这么多钱，城市里的所有人正在议论纷纷。

“weave”与“which“即“cloth”为动宾关系，与句子中其他名(代)词不存在任何关系。

(3)在therebe句型中，不定式可用主动式，也可用被动式。
