名词单数变复数口诀名词单数变复数口诀(一)规则改变名词单数变复数，直接加-s占多数；s,x,ch,sh来结尾，直接加上-es；词尾是f或fe，加-s之前先变ve；辅母+y在词尾，把y变i再加-es；词尾字母若是o，惯用三个已足够，要加-es请记好，hero,tomato,potato。第1页1.英语名词有单数和复数区分，单数表示“一”，复数表示“多于一。”名词由单数变复数，多数是规则变，直接加-s，比如：bookbooks,girlgirls。但以-s,-z,-x,-ch,-sh结尾名词，变成复数时加-es,比如：busbuses,buzzbuzzes,boxboxes,watchwatches,brushbrushes第2页2.-f(e)结尾名词单数变复数歌诀：树叶半数自已黄，妻子拿刀去割粮，架后窜出一只狼，就像强盗逃命忙。比如：leaf(树叶，叶子)，half(二分之一)，self(自已)，wife(妻子)，knife(刀子)，shelf(架子)，wolf(狼),thief(窃贼，强盗)和life(生命)，这些名词变成复数时，都要改-f(e)为v，再加-es。第3页4.辅音字母+y结尾名词，把y变i加-es。比如：babybabies,countrycountries,familyfamilies；而-y前是元音时，-y不变，直接加-s。比如：daydays,boyboys第4页5.以-o结尾名词变复数时，多数直接加-s。比如：radioradios,pianopianos,kangarookangaroos；有须加-es，中学书本中有几个这么单词，能够经过一句口诀来记忆：黑人英雄爱吃西红柿和土豆。即NegroNegroes,heroheroes,tomatotomatoes,potatopotatoes；第5页(二)不规则改变男人女人a变e，鹅足牙oo变ee；老鼠虱婆也好记，ous变ic；孩子加上ren，鱼鹿绵羊不用变。6.名词复数不规则改变需要尤其记忆。比如manmen,womanwomen,goosegeese,footfeet,toothteeth,mousemice,louse(虱子)lice,childchildren,fishfish,deer(鹿)deer,sheepsheep等。第6页初中书本中表示“某国人”名词复数形式改变可经过歌诀记忆：中日不变英法变，其余-s加后面。比如ChineseChinese,JapaneseJapanese；EnglishmanEnglishmen,EnglishwomanEnglishwomen,FrenchmanFrenchmen,FrenchwomanFrenchwomen；AmericanAmericans,RussianRussians,ArabArabs,GermanGermans等第7页写出以下名词复数形式1、orange2、class3、text4、monkey5、piano6、child7、shelf8、bed9、country10、family11、toy12、foot13、Japanese14、radio15、photo16、army17、tomato18、fox19、woman20、knife22、sheeporangesclassestextsmonkeyschildrenshelvesbedscountriesfamiliestoysJapaneseradiosphotostomatoesfoxespianosfeetwomenknivessheeparmies第8页二、用所给单词复数正确形式填空：1Therearesomany_(wolf)intheforest.2.Therearethree_(chair)intheclassroom.3.These_(tomato)arered.4._(hero)aregreat.5Mybrotherlooksaftertwo_(baby)6Therearesome_(deer)eatingthegrass.7Myfatherlikestoeat_(potato).8Chinese_(people)liketoeatnoodles.9Ihavealotof_(toy)inmybedroom.10Ihelpmymotherwash_(dish)inthekitchen.wolveschairstomatoesHeroesbabiesdeerpotatoespeopletoysdishes第9页11Ihavetwo_(pencil-box).12Therearesome_(bus)inthestreet.13Peterhaseight_(foot).14Lindahasthree_(tooth).15Therearesome_(child)inthegarden.16Michaellikesthe_(mouse).17Therearesome_(goose)intheriver.18Myuncleandfatherare_(man).19TomandKingare_(boy).20Lindahasthree_(tooth).pencil-boxesbusesfeetteethchildrenmicegeesemenboysteeth第10页1Icanseethree_inthezoo.AmonkeiesBmonkeysCmonkey2.Thepighasfour_.A.footB.feetC.foots3.Mytwobrothersareboth_.A.policemanB.policemansC.policemen4.Therearefour_intheclass.A.JapaneseB.JapanesesC.Japan5.Icanseeten_inthepicture.A.sheepB.dogC.pig6.The_hasthree_.A.boys,watchesB.boy,watchC.boy,watches7.Canyousee_ontheplate?A.breadB.breadsC.breadesABCBACA第11页8.Thegirloftenbrushesher_beforeshegoestobed.A.toothB.toothsC.teeth9.MrBlackoftendrinksome_.A.milkB.milksC.milkes10.Therearesome_onthefloor.A.childB.waterC.books11._willlearnEnglish.A.WomanB.WomenC.Man12.Lucywillshowussomenew_ofhers.A.photoB.photosC.photoes13.Idranktwo_.A.bottlesoforangeB.bottleoforangeC.bottlesoforanges14.Thecateatstwo_lastnight.A.mousesB.miceC.mouseABCCABB第12页1、Thereonthewall.Theyareverybeautiful.A.arephotoesB.arephotosC.isaphotoD.isphotos2.ThiskindofcarmadeinShanghai.A.isB.areC.wereD.has3.Therearefourandtwointhegroup.A.Japanese,GermenBJapaneses,GermenC.Japanese,GermanC.Japanese,Germans4.Thatsartbook.A.anB.aC.theDare5.Theboyshavegotalready.A.twobreadB.twobreadsC.twopiecesofbreadD.twopieceofbreadABDAC第13页6.Theoldmanwants.A.sixboxesofapplesB.sixboxesofappleC.sixboxofapplesD.sixboxsofapples7.Theresomeintheriver.A.is,fishB.are,fishsC.is,fishsD.are,fish8.Theretwointhebox.A.iswatchB.arewatchesC.arewatchD.iswatches9.Weshouldcleantwiceaday.A.ourtoothB.ourtoothsC.teethD.ourteeth10.The_meetingroomisnearthereadingroom.A.teacherB.teachersC.teachersD.teachers11.InBritain_areallpaintedred.A.letterboxesB.lettersboxesC.letterboxD.lettersboxABCDDA第14页2.找出以下句子中错误并更正：1)Thisisapairoftrouser.这是一条裤子。2)Hegavemesomeadvices.他给了我一些忠言。3)Shewenttothelibrarywithtwoladiesfriends.她和两位女伴一起去图书馆。4)Thepoliceislookingforhim.警察在找他。第15页
