初中英语语法【名词】1.名词的可数与不可数可数名词指表示的人或事物可以用数来计量,它有单数与复数两种形式。不可数名词指所表示的事物不能用数来计量。物质名词与抽象名词一般无法用数目来统计,都是不可数名词。不可数名词前一般不能用冠词a、an来表示数量,没有复数形式。要表示“一个……”这一概念,就须加apieceof这一类短语。要注意许多名词在汉语里看来是可数名词,在英语里却不可数。如:chalk,paper,bread,rice,grass,news等。2.名词的复数(1)规则变化A.一般情况下加-s。B.以s,x,ch,sh,结尾的加-es。如:bus---buses,box---boxes,watch---watches,brush---brushesC.以辅音字母加y结尾的改y为i再加-es。如:city---cities,country---countriesD.以f,fe结尾的,去掉f或fe,变成v再加-es。(2)不规则变化A.元音发生变化。如:man---men,woman---women,foot---feet,tooth---teeth,mouse---miceB.词尾发生变化。如:child---childrenC.单、复数同形。如:fish---fish,Japanese---Japanese,Chinese---Chinese,sheep---sheep\n3.物质名词(不可数名词)量的表示方法(1)用much,alittle,alotof等表示(2)用容器表示abowlofrice,aglassofwater,acupoftea,apieceof,orange,twoglassesofmilk,twopiecesofpaper另外,大家应注意:单数集合名词作主语时谓语动词“数的”变化:单数集合名词如class,police,family,school,group,team等。尽管形式上是单数,意义上都是复数,因此,一般要与复数谓语动词连用,例如:ClassFivehaveaforeignfriend.五班有一位外国朋友。(这里的五班指五班的同学的。)Hisfamilyaregoodtome.他的家人对我很好。(很显然,这里的family指家庭成员。)当上述集合名词着重指“整体”时,意义上则是单数,因此,要与单数谓语动词连用。例如,Ourschoolteamoftenplayswellinourcity.我们的校队经常在我们市踢得很好。(这里的team指整个队,但意义上仍为单数,故谓语动词用plays.4.名词的所有格(1)名词所有格的构成法A.单数名词词尾加’s,复数名词词尾若没有s,也要加’s。theworker'sbike,theChildren’sballB.表示几个人共有一样东西,只需在最后一个人的名字后加’s若表示各自所有,则需在各个名字后’s。如:ThisisLucyandLicy’sroom.TheseareKate'sandjack’srooms.C.如果是通过在词尾加—s构成的复数形式的名词,只加’。如:thestudents’books,thegirls’blouses(2)名词+of+名词名词是有生命的,我们就用’\ns结构来表示所有关系。如果名词所表示的事物是无生命的,我们就要用名词+of+名词的结构来表示所有关系.如:thelegsofthedesk,thedooroftheroom但在表示名词所有格时,’s结构也常可转换成of结构。有些表示时间,距离、国家、城市等无生命的东西的名词,也可以加’s来构成所有格.如:tenminutes'walk,today'snewspaper例题:[例1](1)—Howfarisyourschoolfromhere?—Notveryfar.It'sabouttwenty______walk.A.minute'sB.minutes’C.minutesD.minute(2)Itisabout______fromtheschooltomyhome.A.tenminuteswalkB.tenminutes’walkC.tenminutes’swalkD.tenminute’swalk分析上述两题考查名词所有格的构成及用法。由句意可知空格处所填内容是表示距离的名词,选项中的名词minute和walk存在所有关系,因此必须用名词的所有格。名词所有格的’s也可以加在一个短语之后,若该短语最后一个名词的词尾是-s,则只加“’’。如:anhour’sride,twoweeks’time。因而(1)、(2)小题答案均为B。[例2]Haveyouseen______atthefootofthehill?A.anysheepB.somesheepsC.anysheepsD.somesheep分析此题考查名词复数的特殊例子。sheep的单复数同形;any一般用在疑问句和否定句里,some用在肯定句里。答案为A[例3]—Whoisthemaninthebluecar?—Heis______father.A.Kate'sandMary'sB.KateandMary'sC.KateandMaryD.ofKateandMary分析本题考查名词所有格的构成及方法。两个并列的所有格,只给第二个名词加“’s”。\n[例4](哈尔滨市,2003)---WhereisTom?---He’sleftasayingthathehassomethingimportanttodo.A.excuseB.messageC.exerciseD.news分析此题考查名词的用法,由a知道选项A、C、D不行,故选B。答案选B解后反思anexcuse(一个借口),anexercise(一个练习)……,news(新闻)是不可数名词。[例5](天津市,2003)HehadsomethingtowritedownandaskedmeforA.apaperB.somepapersC.somepiecesofpapersD.apieceofpaper分析此题考查不可数名词的用法。Paper作“纸”讲时是不可数名词,故A、B、C可排除。答案:选D解后反思paper当“试卷”、“文件”讲时是可数名词。类似的词还有:fish,chicken等。练习:1.June1stis___Day.A.Child’sB.Childs’C.Childrens’D.Children’s2.Ineed___paper,Mum.Iwanttowrite___lettertomyEnglishteacher.A.any,someB.some,aC.a,someD.some,any3.Therearetwo___andthree___onthetable.A.knifes,forksB.knifes,forkC.knives,forkesD.knives,forks4.Wehavegotalotof___today.A.newspapertoreadB.homeworktodoC.homeworkstodo\nD.booktoread5.Wecouldsee__childrenandhear___noiseinthepark.A.many,manyB.much,muchC.many,muchD.much,many6.Willyoupassme___?A.afewpiecesofchalkB.afewchalksC.afewofchalksD.somechalks7.___hasbeeninvitedtothedancingparty.A.AfriendofherB.AfriendofhersC.FriendsofhersD.Friendsofher8.September10this___Day.A.theTeacherB.Teachers’C.TeacherD.Teacher’s9---CanIhelpyou,sir?---I’dliketohave100___.Iwantthestudentstodrawpicturesonthem.A.pieceofpaperB.piecesofpaperC.papersD.paper10.---Wouldyoulike___milk,please?---No,thankyou.Istillhavesome.A.somemoreB.anC.alittleofD.all11.___theoldwomanisin!A.WhatgoodhealthB.HowagoodhealthC.WhatagoodhealthD.Howgoodhealth答案:D.B.D.B.C.A.B.B.B.A.A选择正确答案1.Thereareforty______inourschool.A.womenteachersB.teacherwomenC.womanteachersD.womenteacher2.Mr.Liisoneof______inthehospital.\nA.mostpopulardoctorsB.themostpopulardoctorsC.mostpopulardoctorD.themostpopulardoctor3.Thesign"NOPHOTOS"meansthatyoucan't______.A.takepicturesB.bringinpicturesC.buyanyphotosD.sellanyphotos4.Someoftheboysin______areafraidofmathsexams.A.ClassThreeB.theClassThreeC.ThreeClassD.theThreeClass5.Haveyougotany______forusthistime?A.piecesofmessageB.pieceofmessagesC.piecesofmessagesD.messages6.______,thosemountainswillbecoveredwithtrees.A.InafewyearstimeB.AfterafewyearstimeC.Inafewyears’timeD.Afterafewyearstime7.HongKongisanSARwhileMacaoisanother.Sothereare______inChina.A.bothSARB.bothSARSC.twoSARD.twoSARS8.Look!Thereare______starsupthereinthe______.A.thousandsof;skyB.thousandsof;airC.thousandof;skyD.thousandof;air9.Myfatherlivedin______forsometenyears.A.cityBeijingB.theBeijingcityC.BeijingofcityD.thecityofBeijing10.Justfromthe______Iknowit'sLiuMinjun.A.noiseB.voiceC.soundD.sing11.—Wherearetheothertwostudents?—They'rein______.A.teacher'sofficeB.teachers'office\nC.theteacherofficeD.theteachers'office12.—Howmany______haveyounextterm?—Letmesee.We'llhaveeight.A.lessonB.subjectsC.daysD.class13.Myuncle'sfullnameisDavidEdwardHartpode.Hisfamilynameis______.A.EdwardB.HartpodeC.DavidD.DavidHartpode14.Hewritesmorecarefullythan______inhisclass.A.anystude

with多指用工具,用身体的部位或器官;by表示使用的方法、手段;in指使用某种语言。如:Weseewithoureyes.Wegotherebybike.PleasesayitoutinEnglish.Hecutitopenwithaknife.介词的省略表示时间介词at,on,in的省略\n(1)在next,last,this,these,today,yesterday,tomorrow,one,every,each,all等词前,一般不用at,in,on.(2)在某些名词词组前,可以省略(也可不省)如:(on)thatday,(in)theyearbeforelast常见搭配:1.动词+介词,如:listento,laughat,writeto,hearfrom,getto,lookat,shoutat,shoutto,knockat,lookfor,lookat,askfor,waitfor,geton,getto,puton,turnon,operateon,takeoff,turnoff,learnfrom,worryabout...2.形容词+介词,如:afraidof,fullof,angrywith,strictwith,busywith,goodat,good/badfor,latefor,sorryfor,readyfor,famousfor,politeto,farfrom...3.名词+介词/介词+名词keyto,visitto,athome,insurprise,afterclass,forever,ontime,atlast,atfirst,forexample...[例1]用正确的介词填空。1)Thelittlegirlislooking________hermother.2)Thankyou________yourhelp.3)Don'tread________bed.4)Tomcomes________theUSA.第1小题要填for,因为lookfor是一个固定词组,表示寻找的行为。第2小题填for,既可说Thanksfor…也可以说Thankyoufor…,for后接名词。第3小题填in。表示“在床上”inbed,一般不说onbed。第4小题comefrom一个固定短语,意思相当于befrom,表示“来自…”。[例2]Chinalies_______theeastofAsiaand______theeastofJapan.A.in;onB.to;toC.to;inD.in;to解析表示方位的介词in,on,\nto意义各不相同。在范围内的地方用in。China属于Asia范围内,故先用in;不在范围内的地方用to,若两地相连,则要用介词on,China和Japan不属同一范围且有海相隔,故选择to。因此答案为D。用适当的介词填空1.You'dbetternotgo______theforest.It'sdangerous.2.Whichroomareyougoingtolive______?3.Thebuildingis______fire.There'resomepeople______thetopfloor.4.Before1990therewasnoairline______thetwocities.5.It'snotgoodtocomelate______school.6.What'swrong______yourbike?7.Thankyouverymuch______comingtoseeme.8.Icouldn'tfinishit______yourhelp.9.Don'tlaugh______others’mistakes.10.Dothetwinslook______theirfather?11.—Howdoyouusuallycometoschool,everyday?—Sometimes______bike,sometimes______foot.12.It'sverykind______youtohelpme______mymaths.13.Don'tread______thesun.It'sbad______youreyes.14.Theteachertoldusthemoontravels______theearth.15.Youmustlearnthesewords______heart,andanswermyquestion______English.16.Pleasemeetyouruncle______noon______Saturday.17.Thanks______yourhelp,Ifinishedtheworkbefore\ndark.18.It'scoldandthetemperatureis______zeroduringthenight.19.Theteacheriswriting______redink______apieceofpaper.20.Thechildrenarewaiting______thegate______theirmother.名词答案:1.A2.B3.A4.A5.D6.C7.D8.A9.D10.B11.B12.B13.B14.B15.A16.B17.A18.B19.C20.A代词答案:1.B2.B3.B4.C5.D6.D7.B8.B9.C10.D11.B12.D13.A14.D15.C16.B17.D18.A19.A20.A冠词答案:1.×;a2.an3.×4.×5.×6.a7.a;×8.×;×;×9.the10.×;×11.the;×;×12.×13.the14.×15.×16.the17.the;×18.the19.the20.The;the数词答案:1-5BADCC6-10BABAA形容词、副词答案:1.thestrongest;three2.better;than3.sodid4.enoughto5.somethingwrong6.snowedheavily7.doesn't;any8.more;else9.too;to10.Nobody;well介词答案:1.through2.in3.on,on4.between5.to6.with7.for8.without9.at10.like11.by;on12.of;with13.in;for14.around/round15.by;in16.at;on17.to18.below19.in;on20.at;for
