高考英语语法-难点易错点归纳解析一、定语从句引导定语从句的关系代词有that,which,who（宾格whom）,所有格whose）和关系副词wherewhenwhy等，关系代词或关系副词在定语从句中充当一个成分，关系代词that,which,who,whom等在从句中分别作主语或宾语，whose在从句中作定语，而关系副词when,where,why等在从句中作状语。如：Iwillneverforgetthedayswhen/inwhichweworkedtogether.解析：在句①中，表示时间的名词thedays在从句中充当的是状语，所以用关系副词when来代指，引导定语从句修饰先行词thedays；而在句②中，表示时间的名词thedays在从句中充当的是动词spent的宾语，所以用关系代词that或which来代指。同样，表示地点或原因的名词如果在从句中作状语，则用关系副词where或why来代指；如果在从句中作动词的宾语，则用which或that来代替。如：①Thisisthefactorywhere/inwhichIworked.（作状语）②Thisisthefactorythat/whichIvisitedyearsago.（作宾语）注：当先行词为time,reason,place时，引导词可以省略。如：Thiswasthefirst（when/what）Ihadserioustroublewithmyboss.Thatisthereason（why）Ididit.Thisistheplace（where）wemetyesterday.另外，定语从句中谓语动词的数应与先行词的数相一致。如：①Mr.Jacksonistheonlyforeignerthatispresentattheparty.②Heisoneofthestudentswhowerepraisedbytheteacher.解析：在句①中，先行词foreigner被only修饰，强调只有一个，所以从句中谓语动词用单数形式，而在句②中，who引导的定语从句修饰先行词thestudents,为复数，所以从句谓语动词应为复数。二名词性从句中的易错点（一）that引导的定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从句同位的名词必须是一些表示事实或概念的抽象名词，如：fact,news,belief,truth,reply等。That在定语从句中必须作成分，可用which或who/whom代替，而that在同位语从句中不充当任何句子成分，只起连接作用。如：AlongwiththeletterwashispromisethathewouldvisitmethiscomingChristmas.Doyoustillrememberthechickenfarmthatwevisitedthreemonthsago.解析：在句①中，that引导同位语从句解释说明promise的内容，that不充当任何句子成分，只起连接作用，而在句②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。（二）名词性从句中，关于it作形式主语和形式宾语的易错点1）名词性从句作主语或宾语时，为保持句子平衡，常用it作形式主语或形式宾语。如：It'sapitythathedon'tcometogiveaspeech.（形式主语）Wethinkitpossiblethatyoucanfinishthejobtoday.（形式宾语）2）谓语动词appreciate,dislike,hate,like,love,make等接由if或when引导的宾语从句时往往在从句前加上形式宾语it.例如:Iwouldappreciateitifyoucouldcometomybirthdayparty.3）动词hare,take,hide,punish,put等,后接由that引导的病因从句式，往往在从句前加形式宾语it.例如：ItakeitthatyouwillbeleavingShanghaisoon.wepunisheditthatwehadfinishedtheprojectaheadoftime.4）短语动词answerfor,countondependon,insiston,seeto等后接有that引导的宾语从句时，必须冠以形式宾语it.例如：①I'mcountingonitthatyouwillcome.②She’llseetoitthathegoesahead.注：作形式主语和形式宾语时只能用it.三、代词it、one、that的用法与区别One泛指，指代前面提到的那类人或物，用于指代可数名词，相当于a+名词单数，其复数形式ones前一般要有定语，否则就要用some.That（those复数）即可指代不可数名词，表特指，相当于the+名词，后面经常与介词修饰语连用。It指代上文出现的名词，表示同类同物，另外还可表示时间、距离、天气、还可指代人称代词，表示性别身份不明，可作形式主语，形式宾语，引导强调句式以及一些固定搭配，如：getit,catchit,makeit.例如：①Ihavelostmywatch.IthinkImustbuyone.我丢了只表，我想我必须再买一只。（代指上文指到的同类事物，但不指同一个）Whereismypen?Haveyouseenit?我的钢笔不知弄到哪去了，你见了吗？（代指上文提到的同一事物）ThelandofChinaislargerthanthatofAmerica.Tomehasaredpenandablueone（或twoblueones）Hehasnochild,andhewantstoadoptone（或some）四、虚拟语气I虚拟语气在if引导的条件句中的易错点。①ifmylawyerhadbeenherelastSaturday,hewouldhavepreventedmefromgoing.ifyouhadstudiedhardatschool,youwouldbeacollegestudentnow.句子①②都是虚拟语气在条件句中的使用，从句中都是假设过去的情况，所以用过去完成时，但在主句中，句①依然指代过去的情况，谓语动词是wouldhavedone，而②中含有一个表示现在的时间状语now,这样就必须将其理解为假设现在的情况，所以谓语动词必须为would/should/might+动词原形，学生在这一点上经常会忽略now的存在，从而按句①的形式填写答案。口虚拟语气在名词性从句中的用法.在itisimportant(strange,natural,necessary )+that句子或者Itisdecided(ordered,suggested,demanded,advised)+that句子中，主语从句中的谓语动词常用(should)+动词原形结构，表示某事“重要”、“必要”、“被决定”等例如：itisimportantthateveryone(should)obeytherulesalldayandallnight.itisdecidedthatthemeeting(should)beheldtomorrowafternoon..suggest,insist后面指宾语从句时需注意的地方1)①suggest当“建议”“提出”讲时，其后宾语从句的谓语动词常用“should+动词原形”例如：Hesuggestedthatthework(should)bestartedatonce他建议立即动工。类似的动词还有insist坚持，demand要求，desire要求、请求，request请求，require要求、需要，order命令，propose建议，command命令，ask要求，advise建议，prefer宁愿等。这些动词变被动语态(如：Itissuggested+that主语从句)形式后，主语从句谓语动词仍用“(should)+动词原形”这些动词变名词(如suggestion)后，其后的表语从句和同位语从句中的谓语部分仍用“(should)+动词原形”©suggest当“提出(某看法)，暗示，启发”讲时，其后宾语从句的动词不用虚拟语气。例如：Thepolicesuggestedthatthethiefmightbeoneofthefamilymember警察局提出窃贼可能是一名家庭成员。Heryawnssuggeststhatsheissleepy.她打哈欠表明她困了。Althoughhedidn’tsuggestthatwe__thedecisiontoswimacrosstheriver,buthislooksuggestedthatourdecision__wrong.虽然他没提出我们应该终止游过这条河的决定，但他的表情表明我们的决定是错误的。A：stop;wasB:shouldstop;beC:stopped;wasD:stopped;shouldbe在这个句子中，前一个suggest当“建议”“提出”讲，而后一个作“表明”讲，所以答案为“A”2）①insist作“坚决要求…该…；坚持认为…定要…”讲时，其后宾语从句的谓语动词用“（should）+动词原形”例如：Iinsistedthatyou（should）bethereontime.我坚持认为你应该准时到那里去②insist作“坚持（意见，看法）；坚持说，确信”讲时，其后从句不用虚拟语气。如：Hesuggested（that）heheardsomeoneinthenextroom.他坚持说他听到隔壁屋子里有人。五.反意疑问句中的易错点.在一般疑问句中，无论肯定的问或是否定的问，如果回答为肯定则用yes，反之则用no.特别注意如果出现省略则看下文所暗示的意义。①一Areyouanewcomer?—Yes,Icamehereonlyyesterday.②一Isn'tTomagoodstudent?-Yes,heisexcellent.③一Don'tyouthinkthecompositiongood?一No,Itcan'tbeanyworse.注意：在②③句中，当回答的意思与问句相一致时，则用No,译为“是的”，当回答的意思与问句相反时，则用Yes，译为“不”.情态动词mustImustleavenow,mustn'tI?Hemustbeintheclassroom,isn't?（表推测）Hemusthavefinishedhishomework,hasn'the?（表现在的结果）Hemusthavefinishedhishomeworkyesterdayafternoon,didn'the?（表过去）当句子中有表示猜测的情态动词时，其反意疑问句的构成不能再用原句中的情态动词，而应根据原句在去掉情态动词的情况下的主谓关系来确定其反问形式。六、非谓语动词中的易错点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（强调动作正在进行）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结构（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。如：Havingbeenillinbedfornearlyamonth,hehadahardtimepassingtheexam.解析：从这个句子可以看出，句词的逻辑主语与句子的主语he一致，并且是主谓关系，所以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之前，故采用了现代分词的完成式。InordertoimproveEnglish, .Jenny’sfatherboughtheralotoftapes.Jenny’sfatherboughtalotoftapesforherself.AlotoftapeswereboughtbyJenny.AlotoftapeswereboughtbyJennyfather.解析：根据不定式短语我们可以推知，句子的逻辑主语应该是人而不是物，所以，应该排除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.A.ItisfineB.ItfineC.BeingfineD.Itbeingfine解析：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，所以要加上自己的逻辑主语It，由于不存在主、被动关系，故不能选C项，而应该选D项。————moreattention,thetreescouldhavegrownbetter.A.GivenB.TogiveC.GivingD.Havinggiving解析：give与主句的主语之间是被动关系，故选A.如为主动关系则选C.附赠-100个中国成语的英文版爱屋及乌Loveme,lovemydog.百闻不如一见Onelookisworthathousandwords.比上不足，比下有余Tofallshortofthebest,butbebetterthantheworst.笨鸟先飞Aslowsparrowshouldmakeanearlystart.不遗余力Sparenoeffort;goallout;doone'sbest.不打不成交Nodiscord,noconcord.拆东墙补西墙RobPetertopayPaul.辞旧迎新Bidfarewelltotheoldandusherinthenew.大事化小，小事化了Tryfirsttomaketheirmistakesoundlessseriousandthentoreduceittonothingatall.大开眼界Broadenone'shorizon;beaneye-opener.国泰民安Thecountryflourishesandpeopleliveinpeace.过犹不及Goingbeyondthelimitisasbadasfallingshort;excessisjustasbadasdeficiency;toomuchisasbadastoolittle.好了伤疤忘了疼Onceonshore,onepraysnomore.好事不出门，坏事传千里Badnewstravelsfast.和气生财Harmonybringswealth;friendlinessisconducivetobusinesssuccess.活到老学到老Nevertoooldtolearn.既往不咎Letbygonesbebygones.金无足赤，人无完人Therearespotsevenonthesun.金玉满堂Treasuresfillthehome.脚踏实地Bedown-to-earth.脚踩两只船Sitonthefence;beafence-sitter;haveafootineithercamp.君子之交淡如水Ahedgebetweenkeepsfriendshipgreen.已成定局Cutanddried.礼尚往来Courtesycallsforreciprocity.留得青山在，不怕没柴烧Wherethereislife,thereishope.马到成功Achieveimmediatevictory;wininstantsuccess.名利双收Gainbothfameandwealth.茅塞顿开Besuddenlyenlightened.没有规矩，不成方圆Nothingcanbeaccomplishedwithoutnormsorstandards.每逢佳节倍思亲Onfestiveoccasionsmorethaneveronethinksofone'sdearonesfaraway.谋事在人，成事在天Manproposes;Goddisposes.弄巧成拙Makeafoolofoneselfintryingtobesmart.赔了夫人又折兵Sufferadoubleloss;losethebaitalongwiththefish.抛砖引玉Amodestspurtoinduceotherstocomeforwardwithvaluablecontributions;throwasprattocatchamackerel.破釜沉舟Cutoffallmeansofretreat;burnone'sownwayofretreatandbedeterminedtofighttotheend.抢得先机Takethepreemptiveopportunities.巧妇难为无米之炊Onecan'tmakebrickswithoutstraw.千里之行始于足下Athousand-lijourneybeginswiththefirststep--thehighesteminenceistobegainedstepbystep.前事不忘，后事之师Pastexperience,ifnotforgotten,isaguideforthefuture.前怕狼，后怕虎Fearwolvesaheadandtigersbehind;hesitateindoingsomething.强龙难压地头蛇Themightydragonisnomatchforthenativeserpent.瑞雪兆丰年Afallofseasonalsnowgivespromiseofafruitfulyear.人逢喜事精神爽Peopleareinhighspiritswheninvolvedinhappyevents.世上无难事，只怕有心人Wherethereisawill,thereisaway.世外桃源Aretreatawayfromtheturmoiloftheworld.人之初，性本善Humansareborngood.上有天堂，下有苏杭Justasthereisparadiseinheaven,thereareSuzhouandHangzhouonearth塞翁失马，焉知非福Ablessingindisguise;Everycloudhasasilverlining.三十而立Amanshouldbeindependentattheageofthirty./Atthirty,amanshouldbeabletothinkforhimself.水涨船高Ashipriseswiththetide时不我待Timeandtidewaitfornoman.杀鸡用牛刀Useasteam-hammertocracknuts.实事求是Seektruthfromfacts;bepracticalandrealistic;betruetofacts.说曹操，曹操到Speakofthedevil.实话实说Speaktheplaintruth;callaspadeaspade;tellitasitis.实践是检验真理的唯一标准Practiceisthesolecriterionfortestingtruth.韬光养晦Hideone'scapacitiesandbideone'stime.糖衣炮弹Sugar-coatedbullets.天有不测风云Anythingunexpectedmayhappen.aboltfromtheblue.团结就是力量Unityisstrength.跳进黄河洗不清EvenifonejumpedintotheYellowRiver,onecannotwashoneselfclean-there'snothingonecandotoclearone'sname歪风邪气Unhealthytrendsandvulgarpractices.物以类聚，人以群分Birdsofafeatherflocktogether.望子成龙Holdhighhopesforone'schild.唯利是图Seeknothingbutprofits;beblindtoallbutone'sowninterests.无中生有Asheerfabricationoutofnothing;fabricaterumorsoutofthinair.无风不起浪Therearenowaveswithoutwind.Nothingcomesofnothing.徇私枉法Twistthelawtosuitone'sownpurpose.新官上任三把火Anewbroomsweepsclean.蓄势待发Accumulatestrengthforatake-off.心想事成Mayallyourwishcometrue.心照不宣Haveatacitunderstanding;thoroughlyunderstandeachother,withouthavingexchangedawordofexplanation.先入为主Firstimpressionsarefirmlyentrenched.先下手为强Hewhostrikesfirstgainstheadvantage.Thebestdefenseisoffense.热锅上的蚂蚁Antsonahotpan现身说法Warnpeoplebytakingoneselfasanexample.息事宁人Pouroilontroubledwaters;patchupaquarrelandreconcilethepartiesconcerned.循序渐进Proceedina
