..名词复数名词在使用中的难点在于名词的数，即可数名词与不可数名词的实际应用。所以它具有单数形式和复数形式两种。可数名词复数形式的构成规律是：1.一般情况加s,如：pen—pens,doctor—doctors,boy—boys,其读音规则是在清辅音后读［s］，在元音和浊辅音后读［z］。如:map—map，boy—boys.2.在以s,sh,ch,x结尾的名词后面加es，如：bus—buses,class—classes,其读音为［iz］。3.以ce,se,ze,(d)ge结尾的名词加s，其读音为［iz］。4.以辅音字母加y结尾的名词，要将y变为i再加es，读作［z］，如：factory—factories,country—countries,family—families.但要注意的是以元音字母加y结尾的名词的复数形式只加s，如:boy—boys,day—days。5.以o结尾的名词的复数形式一般要加es，但如果o前面是元音字母或外来词，缩写词以o结尾的则只加s，有生命的要加es没有生命的加s如：tomato—tomatoes,hero—heroes;potato-potatoesnegro-negroesphoto—photos,radio—radios,piano—pianos6.以f或fe结尾的名词的复数形式要将f或fe变为v再加es，如：knife—knives,leaf—leaves,但有些例外的词如roof的复数形式..是roofs。7.不规则名词的复数形式是要单个记忆的，它没有规律可循，如:man—men,woman—women,child—children,foot—feet,tooth—teeth,mouse—mice8.单复同形的名词有：fish,sheep,deer…9.单数形式但其意为复数的名词有:people,police,family等。名词还有格的变化，其主格可作主语，宾格可作宾语。还有所有格，用来表示人或物的所有，以及领属关系。表示有生命的名词的所有格其单数形式是加's其复数形式是s'，如其结尾不是s的复数形式仍加's，如：astudent'sroom,students'rooms,Children'sDay.在表示时间、距离、世界、国家……名词的所有格要用's，如：atwentyminutes'walk.但无生命名词的所有格则必须用of结构，如：thecapitalofourcountry,thecolouroftheflowers英语名词变复数的练习题一、写出下列名词的复数形式1、orange2、class3、text4、monkey5、piano6、child7、shelf8、bed9、country10、family11、toy12、foot13、Japanese14、..radio15、photo16、army17、tomato18、fox19、woman20、knife22、sheep二、选择填空1、Thereonthewall.Theyareverybeautiful.A.arephotoesB.arephotosC.isaphotoD.isphotos2.ThiskindofcarmadeinShanghai.A.isB.areC.wereD.has3.Therearefourandtwointhegroup.A.Japanese,GermenBJapaneses,GermenC.Japanese,GermanD.Japanese,Germans4.That’sartbook.A.anB.aC.theDare5.Theboyshavegotalready（已经）.A.twobreadB.twobreadsC.twopiecesofbreadD.twopieceofbread6.Theoldmanwants.A.sixboxesofapplesB.sixboxesofapple..C.sixboxofapplesD.sixboxsofapples7.Theresomeintheriver.A.is,fishB.are,fishsC.is,fishsD.are,fish8.Theretwointhebox.A.iswatchB.arewatchesC.arewatchD.iswatches9.Weshouldcleantwiceaday.A.ourtoothB.ourtoothsC.teethD.ourteeth10.Theycomefromdifferent______A.countryB.countriesC.acountryD.countrys11.Howmany_____doyouseeinthepicture?A.tomatosB.tomatoesC.tomatoD.thetomato12.Theyare______.A.womanteachersB.womenteachersC.womenteacherD.womanteacher13.Wouldyoulike_______,please?A.twoglassofwaterB.twoglassesofwaterC.twoglassofwatersD.twoglassesofwaters..14.Mostof______livein_______.A.Germans,GermanB.German,GermenC.Germen,GermanyD.Germans,Germany15.Therearesome______inthese_______.A.knifes…pencil-boxesB.knives…pencils-boxC.knives…pencil-boxD.knives…pencils-boxes16.______like______byair.A.Greens,travellingB.TheGreen,travelingC.TheGreens,travelD.TheGreens,travelingA.thepeopleB.peopleC.peoplesD.thepeoples三）.填入所给名词的正确形式1.Ihavetwo_____(knife)2.Therearemany_____here.(box)3.Therearemany_____ontheroad.(bus)4.Afew_____aredrawingonthewall.(boy)5.The_______areplayingfootballnow.(child)..1.Hewaseagertomakesomeextramoney,sinceduringtheseyearshecouldhardlyliveonhis_______.a．littlewageb.fewwagec.waged.wages2.Mostofthehousesinthevillagewereburntto______duringthewar.a.anashb.theashc.ashd.ashes3.Thestudentsatcollegesoruniversitiesaremaking______forthecomingNewYear.a.manypreparationsb.muchpreparationc.preparationsd.preparation4.Paintingin_____isoneoftheirspare-timeactivities.a.oilb.anoilc.oilsd.theoil5.Intheviewoftheforeignexperts,therewasn’t____oilhere.a.muchb.lotsofc.agreatdealofd.many6.Thelargehousesarebeingpainted,but______.a.ofgreatexpenseb.atagreatexpensec.inalotofexpensesd.byhighexpense7.Theroomwassmallandcontainedfartoo______...a.muchnewfurniturec.muchnewfurnituresb.manynewfurnitured.manynewfurnitures8.Jimwaslatefortwoclassesthismorning.Hesaidthatheforgotbothofthe______.a.roomsnumberb.roomnumberc.room’snumbersd.roomnumbers9.Computerscando______workinashorttime,butamancannotdo______byhimself.agreatmany…manyc.much…agreatdealb.agreatdealof…muchd.many…agreatmany10.Shedidn’tknow_____hehadbeengiven.a.howmanyinformationc.howmanyinformationsb.thenumberofinformationd.howmuchinformation11.Heinvitedallofhis______tojoinhisweddingparty.a.comrade-in-armsc.comrades-in-armb.comrades-in-armsd.comrade-in-arm..12.Allthe______inthehospitalgotariselastmonth.a.womendoctorsc.womandoctorsb.womendoctord.womandoctor13.Aftertenyears,alltheseyoungstersbecame_____.a.growns-upsc.growns-upb.grown-upd.grown-ups14.Thepoliceinvestigatedthose_____abouttheaccident.a.stander-byc.standers-byb.stander-bysd.standers-bys15.TheNazikeptthose______intheirconcentrationcamp.a.prisoner-of-warsc.prisoners-of-warb.prisoners-of-warsd.prisoner-of-war16.Themanagerwasgreatlyappreciatethat_____madebyLindalately.a.newreelb.newsreelc.new-reelsd.newsreels17.Mary’sdressissimilarinappearancetoher______...a.eldersisterb.eldersister’sc.eldersistersd.eldersistersdress18.Allthepeopleattheconferenceare______.a.mathematicteachersc.mathematicsteacherb.mathematicsteachersd.mathematic’steachers19.ProfessorMackaytoldusthat______ofleadareitssoftnessanditsresistance.a.somepropertyc.propertiesb.somepropertiesd.property20.Physics_____withmatterandmotion.a.dealb.dealsc.dealingd.are21.Hehaswrittenseveralbooks,buthislastworks_____wellknownamonghisfriends.a.haveb.havebeenc.isd.are22.Afterhechec
