名词变复数及练习题

名词单数变复数口诀(一)规则变化名词单数变复数，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，常用三个已足够，要加-es请记好，hero,tomato,potato。1.英语名词有单数和复数的区别，单数表示“一”，复数表示“多于一。”名词由单数变复数，多数是规则的变，直接加-s，例如：book→books,girl→girls。但以-s,-z,-x,-ch,-sh结尾的名词，变成复数时加-es,例如：bus→buses,buzz→buzzes,box→boxes,watch→watches,brush→brushes2.-f(e)结尾的名词单数变复数歌诀：①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。例如：leaf(树叶，叶子)，half(一半)，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。4.辅音字母+y结尾的名词，把y变i加-es。例如：baby→babies,country→countries,family→families；而-y前是元音时，-y不变，直接加-s。例如：day→days,boy→boys5.以-o结尾的名词变复数时，多数直接加-s。例如：radio→radios,piano→pianos,kangaroo→kangaroos；有的须加-es，中学课本中有几个这样的单词，可以通过一句口诀来记忆：黑人英雄爱吃西红柿和土豆。即Negro→Negroes,hero→heroes,tomato→tomatoes,potato→potatoes；(二)不规则变化男人女人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.名词复数的不规则变化需要特别记忆。例如man→men,woman→women,goose→geese,foot→feet,tooth→teeth,mouse→mice,louse(虱子)→lice,child→children,fish→fish,deer(鹿)→deer,sheep→sheep等。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、sheeporangesclassestextsmonkeyschildrenshelvesbedscountriesfamiliestoysJapaneseradiosphotostomatoesfoxespianosfeetwomenknivessheeparmies二、用所给的单词的复数的正确形式填空：1．Therearesomany________(wolf)intheforest.2.Therearethree______(chair)intheclassroom.3.These_______(tomato)arered.4.______(hero)aregreat.5．Mybrotherlooksaftertwo______(baby)6．Therearesome____(deer)eatingthegrass.7．Myfatherlikestoeat_______(potato).8Chinese______(people)liketoeatnoodles.9．Ihavealotof______(toy)inmybedroom.10．Ihelpmymotherwash______(dish)inthekitchen.wolveschairstomatoesHeroesbabiesdeerpotatoespeopletoysdishes11．Ihavetwo______(pencil-box).12．Therearesome______(bus)inthestreet.13．Peterhaseight_____(foot).14．Lindahasthree_______(tooth).15．Therearesome______(child)inthegarden.16．Michaellikesthe______(mouse).17．Therearesome______(goose)intheriver.18．Myuncleandfatherare_____(man).19．TomandKingare_____(boy).20．Lindahasthree______(tooth).pencil-boxesbusesfeetteethchildrenmicegeesemenboysteeth1．Icanseethree________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.breadesBCBC8.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.mouseABCCABB1、Thereonthewall.Theyareverybeautiful.A.arephotoesB.arephotosC.isaphotoD.isphotos2.ThiskindofcarmadeinShanghai.A.isB.areC.wereD.has3.Therearefourandtwointhegroup.A.Japanese,GermenBJapaneses,GermenC.Japanese,GermanC.Japanese,Germans4.That’sartbook.A.anB.aC.theDare5.Theboyshavegotalready.A.twobreadB.twobreadsC.twopiecesofbreadD.twopieceofbreadABDAC6.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.teacher’sC.teachers’D.teachers11.InBritain_____areallpaintedred.A.letterboxesB.lettersboxesC.letterboxD.lettersboxABCDDA2.找出下列句子中的错误并改正：1)Thisisapairoftrouser.这是一条裤子。2)Hegavemesomeadvices.他给了我一些忠告。3)Shewenttothelibrarywithtwoladiesfriends.她和两位女伴一起去图书馆。4)Thepoliceislookingforhim.警察在找他。单数句变复数句1Thisisanapple.(变复数句)2That’sabook.(变复数句)3ThoseareEnglishmaps.(变单数句)4It’sawatch.(变复数句)5Heisn’tmyfriend.(变复数句)6Theyaresomeboys.(变单数句)7Iamastudent.(变复数句)8Thisisn’thisdictionary.(变复数句)9Theseareorangetables.(变单数句)10Whereishisbox?(变复数句)11Whereareherwatches?(变单数句)12Thepenisintheroom.(变复数句)13Thosearen’tmyphotos.(变单数句)14Arethesepotatoes?(变单数句)单数句变复数句精炼一将下列单数句变为复数句1Thisisabook.2Isthatapen？3Sheisagirl.4Ilikeher.5Thebookismine.6Thisisherpen.7Iamateacher.8Heisaboystudent.9Sheisawomanworker.10Helikeshisbike.二将下列复数句变为单数句1Whatarethese？2Theyliketheirbikes.3Thesearemybooks.4Theseare（some）books.5Arethose（any）pens？6Theyaregirls.7Welikethem.8Theseare（some）books.9Arethose（any）pens？10Theylikemybikes.
