名词变复数及练习题08309.ppt

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：bookbooks,girlgirls。但以-s,-z,-x,-ch,-sh结尾的名词，变成复数时加-es,例如：busbuses,buzzbuzzes,boxboxes,watchwatches,brushbrushes,2.-f(e)结尾的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。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：babybabies,countrycountries,familyfamilies；而-y前是元音时，-y不变，直接加-s。例如：daydays,boyboys,5.以-o结尾的名词变复数时，多数直接加-s。例如：radioradios,pianopianos,kangarookangaroos；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NegroNegroes,heroheroes,tomatotomatoes,potatopotatoes；,(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manmen,womanwomen,goosegeese,footfeet,toothteeth,mousemice,louse(虱子)lice,childchildren,fishfish,deer(鹿)deer,sheepsheep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、sheep,oranges,classes,texts,monkeys,children,shelves,beds,countries,families,toys,Japanese,radios,photos,tomatoes,foxes,pianos,feet,women,knives,sheep,armies,二、用所给的单词的复数的正确形式填空：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.,wolves,chairs,tomatoes,Heroes,babies,deer,potatoes,people,toys,dishes,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-boxes,buses,feet,teeth,children,mice,geese,men,boys,teeth,1Icanseethree_inthezoo.AmonkeiesBmonkeysCmonkey2.Thepighasfour_.A.footB.feetC.foots3.Mytwobrothersareboth_.A.policemanB.policemansC.policemen4.Therearefour_intheclass.JapaneseB.JapanesesC.Japan5.Icanseeten_inthepicture.sheepB.dogC.pig6.The_hasthree_.boys,watchesB.boy,watchC.boy,watches7.Canyousee_ontheplate?A.breadB.breadsC.breades,A,B,C,B,A,C,A,8.Thegirloftenbrushesher_beforeshegoestobed.A.toothB.toothsC.teeth9.MrBlackoftendrinksome_.milkB.milksC.milkes10.Therearesome_onthefloor.childB.waterC.books11._willlearnEnglish.WomanB.WomenC.Man12.Lucywillshowussomenew_ofhers.photoB.photosC.photoes13.Idranktwo_.A.bottlesoforangeB.bottleoforangeC.bottlesoforanges14.Thecateatstwo_lastnight.A.mousesB.miceC.mouse,A,B,C,C,A,B,B,1、Thereonthewall.Theyareverybeautiful.A.arephotoesB.arephotosC.isaphotoD.isphotosThiskindofcarmadeinShanghai.A.isB.areC.wereD.has3.Therearefourandtwointhegroup.A.Japanese,GermenBJapaneses,GermenC.Japanese,GermanC.Japanese,Germans4.Thatsartbook.A.anB.aC.theDare5.Theboyshavegotalready.twobreadB.twobreadsC.twopiecesofbreadD.twopieceofbread,A,B,D,A,C,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.lettersbox,A,B,C,D,D,A,2.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)2Thatsabook.(变复数句)3ThoseareEnglishmaps.(变单数句)4Itsawatch.(变复数句)5Heisntmyfriend.(变复数句)6Theyaresomeboys.(变单数句)7Iamastudent.(变复数句),8Thisisnthisdictionary.(变复数句)9Theseareorangetables.(变单数句)10Whereishisbox?(变复数句)11Whereareherwatches?(变单数句)12Thepenisintheroom.(变复数句)13Thosearentmyphotos.(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.9Sheis
