高中英语语法要点易错点

1、(圆满word版)高中英语语法重点易错点(圆满word版)高中英语语法重点易错点16/16(圆满word版)高中英语语法重点易错点高考语法重点和易错点语法一=从句从句的做题思路=判断是什么从句一、对于定语从句（前提：懂得判断是哪一种从句）1修饰某一名词或代词的句子叫定语从句。2连结词that/which/who/whom/whose/when/where/why/asWhat/how既起连结作用/有充任句子成分3先行词n./pron被定语从句修饰的依照先行词选择连结词物：which/that/whose人：who/whom/that/whose时间：when/which/that地址：wher

2、e/which/thatReason:从句圆满why/forwhich；从句不圆满which/that/-Way:从句圆满inwhich/that/-;从句不圆满which/that/-Idontlikethewayyouspeaktoyourparents.Hefoundthewaywasreasonabletosolvetheproblem.答案：inwhich/that；which/that当先行词与连结词后边的名词n存在所属关系时（的）物：whose+n.=ofwhich+the+n.=the+n.+ofwhich人：whose+n.=ofwhom+the+n.=the+n.+ofwh

3、omTheroom,ofwhichthewindowfacessouthismine.Thegirl,whosefatherdiedisourmonitor.4只能用that不能够用which(重点前5种情况)1）当先行词是不定代词，如all，everything，anything，nothing，much，few，little，none，theone等。Allthatcanbedonehasbeendone.（2）先行词被all,few，little，no，every等词修饰时。Thereisnodifficultythatwecantovercome.（3）先行词被序数词或形容词的最高等修

4、饰时。ThisisthefirstletterthatIvewritteninJapanese.（4）先行词被theonly,thevery,thelast等修饰时ThisistheverybookthatIamlookingfor.（5）当先行词既有人又有物时。Theytalkedabouttheteachersandschoolsthattheyhadvisited.（6）当先行词是系动词be后边的表语或连结词自己是从句的表语时。Chinaisntthecountrythatsheusedtobe50yearsago.7）当主句是以who，which或what开头的特别疑问句时。Whois

5、themanthatiswaitingatthebusstop？5永远不用that=介词/逗号此后6当先行词是时间/地址时when/where/that/which/-When=介词+which=介词+时间Where=介词+which=介词+地址1Which/that=时间/地址当从句圆满时，用When/Where/介词+which当从句不圆满时，用which/that/-Thisisthefactoryinwhich/wherehisparentsusedtowork.1.Thelibrary_studentsoftenstudywasonfirelastnight.2.Thelibrary

6、,_wasbuiltinthe1930s,needsrepairing.3.Thelibrary_youvisitedyesterdaywasbuiltin1990.Illneverforgettheday_wefirstmetinthepark.Illneverforgetthetime_Ispentoncampus.Illevernforgetthetime_wasspentwithyou.答案：where/inwhich；which/that；which/that；when/onwhich；that/which；_that/which7.as与which的比较：1）在非限制性定语从句中，

7、均可取代整个主句.如从句在主句此后，两者皆可用；如从句在主句从前，用as。Theyfailedintheexam，as/whichisnatural.Asisknowntoall，theearthmovesaroundthesun.（2）as“正如，就像”Which“这一点/这个/这件事”Heiscareless,whichcausedtheaccident.Heislateagain,as/whichweexpected.8.当先行词被thesame，such，so修饰时，Thisisthesamebookasyouboughtyesterday.同一类.that同一个Thiswassodi

8、fficultaproblemaswecouldntworkout.（后边句子不圆满）Thiswassodifficultaproblemthatwecouldntworkitout.（后边句子圆满）Thiswassuchadifficultproblem9.其他，定语从句中谓语动词的数应与先行词的数相一致。如：Heisoneofthestudentswhowerepraisedbytheteacher.分析：在句中，先行词foreigner被only修饰，重申只有一个，因此从句中谓语动词用单数形式，而在句中，who引导的定语从句修饰先行词thestudents为复数，因此从句谓语动词应为复数

9、。感悟：学生之因此在这一点上经常出错，主若是对定语从句的理解不够深刻，分辨不出主句和从句，对句子成分的掌握也不到位，搞不清关系代词或关系副词在从句中充任何种句子成分。因此要做好这一类题，要第一弄清关系代词和关系副词的用法，而且应善于分辨和分析句子构造及其相应成分，这样才能因材施教，迅速正确地找到瓿之所在。二、名词性从句主语从句WhatIsayistrue宾语从句HewontbelievewhatIsay.表语从句ThatiswhatIsaid.同位语从句ItoldthemthenewsthatRocketswonthegametoday.差异什么从句应看主句，主句不圆满时从句必定是名词性从句。

10、主句圆满时，从句可能是定语从句，状语从句，或许同位语从句。Ihaveforgottenwherewewentyesterday.2Wherewewentyesterdayiscoveredwithallkindsofflowers.Oh!Thisiswherewecameyesterday.Thisistheplacewherewecameyesterday.Here,hemadethepromisethathewouldcomehere10yearslater.Iwillmakeamarkwherehemadethepromise.需要用什么引导词看从句。名词性从句中缺什么意思用什么意思的引

11、导词;缺名词性成份时，指人用who/whom，指物用what;不缺意思和成份时用that。That只有在宾语从句中能够省略。1._theOlympicGameswillbeheldinBeijingisknown.A.不填B.Whenever2.Thereisacommonbeliefamongthem_rubbishcanandshouldbeputtogooduse.A.whichB.ifC.whetherD.that3.Hesboughtacottageforheretires,withthemoneyhesaved.A.WhenB.whereC.whatD.which(哪一个、哪一些)

12、答案DDA-ItisknowntoallthatTaiwanbelongstoChina.-DoyouthinkitpossiblethatwetakeoverTaiwan?-Ofcourse.It经常在句中当形式主语、宾语，取代真实的主语、宾语，以防备有头无尾。Itisprettywellunderstood_controlstheflowofcarbondioxideinandoutoftheatmospheretoday.Whydontyoubring_tohisattentionthatyouaretoobusytodoit?答案CD表“可否”时只用whether不用if:1.Whet

13、herthepresidentwillcomeisnotknownyet.(主从)Theproblemiswhetherweneedit.（表从）3.Theproblemwhetherwewillbuildanotherschoolhasntbeensettled.（同位语从句）4.HewasworriedaboutwhetherhepassedtheEnglishexamination.（介词此后）5.Itdoesntmatterwhethershewillcomeornot.（whetheror/ornot）Idontknowwhethertogo.（动词不定式从前）差异：that引导的定

14、语从句与同位语从句定语从句与前面的的名词是修饰与被修饰的关系，“的名词”，而同位语从句是用来说明前面名词的内容。与that从句同位的名词必定是一些表示事实或见解的抽象名词，如fact,news,belief,truth,reply等。That在定语从句中必定作成分，可用which或who/whom取代，而that在同位语从句中不充任任何句子成分，只起连结作用。如：AlongwiththeletterwashispromisethathewouldvisitmethiscomingChristmas.3Doyoustillrememberthechickenfarmthatwevisitedth

15、reemonthsago.分析：在句中，that引导同位语从句讲解说明promise的内容，that不充任任何句子成分，只起连结作用，而在句中，that在其引导的定语从句中作动词visited的宾语，对先行词thechickenfarm起修饰作用。感悟：学生之因此在这一点上简单出错，主要仍是由于对定语从句的理解不够深刻，分辨不出that在从句中可否充任了句子成分，因此，还需在句子分析上下功夫，而且搞清何谓同位语从句。三、状语从句（主句圆满，从句和主句之间不存在修饰关系的，一般就是状从）对于when/while/as都有“当时”WhenIarrived,hehadalreadyleft.Mary

16、askedmetocareforherpetwhileshewasaway.（当时）Asthesunsetinthewest,itbecamedarkeranddarker.Astimegoesby/astheeconomydevelopsWhen(正在这时)Beabouttodo.WhenBedoingwhenHadjustdonewhenBeonthepointofdoingwhenwhileHelikespopmusicwhileIamfondofclassicalmusic.(而)Maryaskedmetocareforherpetwhileshewasaway.（当时）WhileIu

18、hina.Asanoldsayinggoes,itsnotuntiltheDragonBoatFestivalthatwecanputawaywarmclothes.2.对于since/before/untilItis/hasbeenseveralmonthssincewelastspenttheholidayinthecountrytogether.Itwastenyearssincewehadhadsuchawonderfultime.BeforeHeleftbeforeIcouldsay“thankyou”tohim.来不及ThreeyearspassedbeforeIknewit.才I

19、twontbelongbeforewehaveamonthlyexam.Itwillbetenyearsbeforewemeetagain.Itwastenyearsbeforetheymetagain.Until/till(主句谓语连续性)Notuntil(主句谓语短暂性)GeorgeworkedforIBMuntil/till2000.直到凑近，我才认出他。Untilhecameuptome,Irecognizedhim.（此句错误）=Ididntrecognizehimuntilhecameuptome.3.对于“一就”HardlywhenNosoonerthanAssoonasThem

20、oment/time/minute/second+句子Immediately/instantly/directly+句子Ondoing/名词Hardly(Nosooner)hadIgothomewhen(than)therainpoureddown.Themomentshesawtherobber,shescreamed.Instantlyhesawthedrowninggirl,hejumpedintotheriver.Uponarrival/Onarrival/Onarriving,Iwillpayavisittoyoufirst.4.Itis/was+时间点+when与重申句型的差异It

21、wasmidnightIfellasleep.Itwasatnoonwearrivedinthevillage.D.that答案AD5.Unless若是不（除非）/if若是_yougoallouttodothework,Idontthinkyoucanachieveyourgoalasplanned.D.TillHeneverspeaks_heisspokento,forheisnotmuchofaspeaker.5D.until答案ACasif(though)忧如/忧如/忧如+真实/虚假evenif/though即使8.incase/forfearthat以防/惟恐9.What/whatev

22、er/nomatterwhat;how/however/nomatterhowWhat(ever)+名词How(ever)+形容词/副词Whateverdifficultieswemeetwith,itisbesttofacethemandtrytosolvethem.Howeverlateitis,Illwaitforyou.Nomatterhowbusyheis,heisreadytohelpothers.Nomatter+疑问词=引导状从疑问词+ever=引导名从/状从Whateveryousay,Iwontbelieveyou.=Nomatterwhat（状语从句）Iwontbelie

23、vewhateveryousay.=anythingthat（宾语从句）Whoever/Nomatterwhocomes,dontlethimin.（状语从句）Whoever/Anyonewholeaveslastshouldturnoffthelights.（主语从句）Where+句子（特别是引导地址状从和定从的差异）Ihaveforgottenwherewewentyesterday.Wherewewentyesterdayiscoveredwithallkindsofflowers.Oh!Thisiswherewecameyesterday.Thisistheplacewhere/inw

24、hichwecameyesterday.Iwillmakeamarkwheretheteacheremphasizes.语法二=非谓语非谓语做题思路1判断主被动2判断时间（要发生/正在进行/已达成）非谓语与其逻辑主语（即动作的执行者或承受者）之间有三种关系，如为主谓关系，则用现在分词或不定式的主动式；如为被动关系则用过去分词、现在分词的被动（重申动作正在进行）或不定式的被动式（动作将进行）；如既无主动也无被动关系则只能用状语从句或独立主格构造（即非谓语加上自己的逻辑主语）。Judging/considering/genrallyspeaking/supposing指说话者的动作，故只用主动式。

25、如：Havingbeenillinbedfornearlyamonth,hehadahardtimepassingtheexam.分析：从这个句子能够看出，句词的逻辑主语与句子的主语he一致，而且是主谓关系，因此用了现在的分词作状语，同时，分词的动作明显地发生在句子的谓语动词动作从前，故采用了现代分词的达成式。InordertoimproveEnglish,_.A.Jennysfatherboughtheralotoftapes.B.Jennysfatherboughtalotoftapesforherself.6C.AlotoftapeswereboughtbyJenny.D.Alotoft

26、apeswereboughtbyJennyfather.分析：依照不定式短语我们能够推知，句子的逻辑主语应该是人而不是物，因此，应该除掉CD，再就是应该是Jenny提高自己的英语，而不是她爸爸，故答案先B.，wedecidedtogooutforawalk.分析：主句主语we与动词短语befine之间既无主动关系与无被动关系，因此要加上自己的逻辑主语It，由于不存在主、被动关系，故不能够选C项，而应入选D项。moreattention,thetreescouldhavegrownbetter.分析：give与主句的主语之间是被动关系，应选A.如为主动关系则选C.易出错的问题一般都是学生在学习中

27、对知识理解不深刻或能力短缺的地方，应实时纠错和成立“错题档案”，还应“小题大做”，存心地把一些易错题予以归类，找出错误根源，总结规律。非谓语=不能够做谓语的动词形式1Doing主动正在进行eg.Themanstandingthereismyteacher.2beingdone被动正在进行eg.Ithinkthebookbeingwrittenbyhimwillsellwell.3havingdone主动已经达成只能做状语eg.Havingfinishedhishomework,hewentouttoplay.4havingbeendone被动已经达成只能做状语egHavingbeentaken

28、careofwell,theoldmanrecoveredsoon.5done被动已经达成fallenleaves(这里表达成，不表被动)6（onlyjust）todo主动将来7tobedoing主动正在进行8tobedone被动将来9tohavedone主动达成10（tohavebeen）done被动达成非谓语Havingdone所表达的动作在谓语动作从前达成，一般放句首做状语。非谓语doing所表达的动作发生和谓语动作几乎同时进行。Havingworkedhardallday,Iwenttobedearly.HavingexperiencedquiteafewearthquakesinHa

29、waiialready,Ididnttakemuchnotice.Havingstudiedvolcanoesnowformanyyears,Iamstillamazedattheirbeautyaswellastheirpotentialtocausegreatdamage.Walkinginthewayofbackhome,suddenlyIsawastorecoveredwithsmoke.、不定式表猜想之外的结果，现在分词表自但是然的结果。Ihurriedhome,onlytofindnobodyin.Hisparentsdiedearly,leavinghimalone.*onlyt

30、odo与doing作结果状语的用法“onlytodo做结”果状语表猜想之外的结果，尤指不快乐的结果。“doing”做结果状语表示必定结果与主句之间含有逻辑上的因果关系。7语法三=虚假语气（一）if虚假从句主句与现在相反bewereWould/should/could/might+V原dodid与过去相反BehadbeenWould/should/could/might+havedone/beendohaddone1.Bewere;与将来相反dodidWould/should/could/might+V原2.wereto+V原3.shoulddo注：1、ifIwereyouWereIyouifI

33、用Itseemsasifitisgoingtorain.Itseemsasifitweretorain.注：mayyou+V原(三)动词：Insist/suggest/advise/recommend/propose/order/command/demand/require/request/desire+(should)do注：动词对应的名词和句型也用（should）do表虚假suggestion/order/adviceItssuggested/orderedthat+（四）Itsnecessary/important/vitalthat(should)do(五)Its(high/about

34、)timethatshoulddo/did8(六)wouldrather+句子1、对现在/将来虚假用did2、对过去虚假用haddone虚假语气在if引导的条件句中的易错点。ifmylawyerhadbeenherelastSaturday,hewouldhavepreventedmefromgoing.ifyouhadstudiedhardatschool,youwouldbeacollegestudentnow.句子都是虚假语气在条件句中的使用，从句中都是假定过去的情况，因此用过去达成时，但在主句中，句仍旧指代过去的情况，谓语动词是wouldhavedone，而中含有一个表示现在的时间状语

35、now,这样就必定将其理解为假定现在的情况，因此谓语动词必定为would/should/might+动词原形，学生在这一点上经常会忽略now的存在，进而按句的形式填写答案。语法四=神情动词表猜想must只用于必定句/表示很有掌握的猜想/翻译成“必定/必定”；can/could用于疑问句和否认句；may/might用于必定句/表示没有掌握的猜想/翻译成“可能或许”mustnthavedone绝对错/是无效选项must必定，“不用”用neednt/donthavetomustnt禁止/禁止一、神情动词+do/be表示对现在行为或动作进行猜想Youvebeenworkingallday.Youmus

36、tbeverytired.Someoneisknockingonthedoor.ItcantbeLucy.Shesstillinthelibraryatthistime.二、神情动词+havedone/havebeen表示对过去行为或动作进行猜想a.musthavedone表示对过去某事的必定猜想。其否认或疑问形式都用can(could)来表示.Sincetheroadiswet,itmusthaverainedlastnight.Hecanthavemissedtheway.Idrewhimamap.“Thedictionaryhasdisappeared.Whocould/canhavet

37、akenit?”b.may/mighthavedonemay/mighthavedone表示推断过去某事“或许”发生了.Icantfindmykeys.Imay/mighthaveleftthemattheschoolyesterday.c.couldhavedone在必定句型中,经常用作宛转的责怪.本能够做什么,而没做;有时也用作猜想.Youcouldhavedoneitbetter.Tomcouldhavetakenthedictionary.d.oughtto/shouldhavedone和oughtnotto/shouldnthavedone本该做而事实上没做本不该做而事实上做了nee

38、dnthavedone本不用做却做了Theusageof“shall”表征采(用在第一、三人称)Shallmydaughterdoyourshoppingforyou?9表许诺(用在第二、三人称)HerfatherpromisedthatheshallbuyheracomputerifshepassedtheNationalCollegeEntranceExam.表命令（正式文件/场合）Ithasbeenannouncedthatcandidatesshallremainintheirseatsuntilallthepapershavebeencollected.Ithasbeenannoun

39、cedthatallthestudentsshallputonmasksbeforegoingtoschoolincasetheyareinfectedwithSARSvirus.Youshallobeymyorders.Heshallleavethecountryatonce.Foreigncountriesshallnotinterfereinourinternalaffairs.Itshallsnowtonight.(表警示)语法五=动词的时态和语态一、英语动词谓语形式包括时态和语态状态过去现在将来时间一般一般过去一般现在一般将来进行过去进行现在进行将来进行达成过去达成现在达成将来达成达

40、成进行现在达成进行共16种时态，高中掌握11种。一般现在时do/does;am/is/are一般过去时did;was/were一般将来时willdo;am/is/aregoingtodo过去将来时woulddo;was/weregoingtodo现在进行时am/is/aredoing过去进行时was/weredoing将来进行时willbedoing现在达成时have/hasdone/been过去达成时haddone/been将来达成时willhavedone/been现在达成进行时Have/hasbeendoing过去达成进行时Hadbeendoing将来达成进行时Willhavebeend

41、oing二、解题技巧：1、找出题目中的有关动词，对它们的时态进行比较，注意各个动作发生的先后次序。2、记忆固定用法，比方：sofar,inthepastfewyear,for+时间段，UptonowBy+now=现在达成时By+过去时间=过去达成时By+将来时间=将来达成时Bytheendof+过去时间lastmonth=过去达成时Bytheendof+将来时间thismonth=将来达成时Bythetime(从句一般现在时)=主句将来达成时过去将来一般过去将来过去将来进行过去将来达成等用现在达成时。10Bythetime(从句一般过去时)=主句过去达成时Bythetimehearrives,

42、wewillalreadyhaveleftXiamen.Bythetimehearrived,wehadalreadyleftXiamen.3、固定用法其实不是绝对的，重点是看语境重申的重点是什么。Petersaid,“IwenttoXiamentwodaysago/yesterday.”PetersaidthathehadgonetoXiamentwodaysbefore/thedaybefore.4、熟记固定公式。This/Itisthefirsttime(that)Ihavecomehere.It/Thiswasthethirdtime(that)hehadmadethesamemist
