名词单数变复数变化新版规则

名词单数变复数变化规则：一．可数名词1．普通名词复数是在名词背面加上“s”，如map→maps，bag→bags，book-books等；2．以s，x，sh，ch结尾词加“es”，如bus→buses，watch→watches，box-boxes等；3．以f或fe结尾名词变复数时,去掉f，fe加ves名词有：half→halvesknife→knivesleaf→leaveswolf→wolveswife→wiveslife→livesthief→thieves4．以o结尾名词变复数时：a）加s名词有（无生命）：photo→photos，piano→pianos，radio→radiosb）加es名词有（有生命）：potato→potatoestomato→tomatoes5．以辅音字母＋y结尾词，变y为i加es，如baby→babies，family-families，study-studies等；以元音字母＋y结尾名词变复数时，直接加s变复数，如monkey→monkeys，holiday→holidays，storey→storeys（楼层）；6.oo变ee单词：foot-feet，goose-geese，tooth-teeth；7.a变e单词：man-men，woman-women，policeman-policemen;8.复数与原形一致单词：fish-fish，sheep-sheep，deer-deer，Chinese-Chinese，Japanese-Japanese;注：1.fish指“鱼肉”时，是不可数名词；2.fish指“鱼多少”时，是可数名词，但单数和复数同行；Therearemanyfishintheriver。3.fish强调鱼“种类“时，复数是“fishes”。Therearemanykindsoffishesintheriver。9.有些名词以-s结尾，但表达是单数意义，例如：news，maths，politics，physics，theUnitedStates等。10.常以复数形式浮现名词，例如：glasses，trousers，shoes，gloves，socks等，要表达她们量时惯用pair，例如：apairofglasses/shoes；复数只需量词变复数，例如：twopairsofshoes11.名词作定语时，不用复数形式，如：ashoeshop。如果要表达复数，则去掉不定冠词，把名词词组中最后一种名词变成复数形式，如：anappletree---appletrees例外：man，woman作定语时，如果背面名词是复数，则man，woman也要跟着变复数。如：awomanteacher----threewomenteachers常用不可数名词：Food，meat，fish，chicken，beef，drink，milk，water，homework，news，information，fun，work，Chinese，English，music等二．名词所有格（一）表达有生命名词所有格1.在单数名词后加---’s，如：theteacher’soffice2.以-s结尾复数名词后加“’”如：theteachers’soffice3.不以-s结尾名词复数后加“’s”，如：theChildren’sPalace4.用and连接两个并列单数名词表达共有时，只需在后一种并列名词词尾加“’s”；如果不是，则需在各个并列名词后分别加“’s”。如：JohnandMary’shouse，John’sandMary’shouse（二）表达无生命名词所有格普通用“of+名词”表达，如：thecapitalofChina（三）双重所有格将’s与of结合一起使用构成双重所有格，例如：a friend of my father’s 我爸爸一位朋友aphotoofmine我一张照片名词单数变复数练习题一、写出下列名词复数形式　　1、orange__________2、class___________3、monkey__________4、piano___________5、child___________6、shelf____________7、bed____________8、country__________9、family___________10、toy__________11、foot__________12、radio__________13、photo__________14、tomato___________15、woman___________16、knife________17、sheep__________18、ship__________19、dish___________20、mouse___________二、用所给单词复数对的形式填空：　　1>Therearethree_____________(chair)intheclassroom.　　2>These_____________(tomato)arered.　　3>Mybrotherlooksaftertwo_____________(baby)　　4>Myfatherlikestoeat_____________(potato).　　5>Chinese_____________(people)liketoeatnoodles.　　6>Ihavealotof_____________(toy)inmybedroom.　　7>Mymotherwash_____________(dish)inthekitchen.　　8>Ihavetwo_____________(pencil-box).　　9>Therearesome_____________(bus)inthestreet.　　10>Monsterhaseight_____________(foot).　　三、选取填空　　()1．Icanseethree________inthezoo.A.monkeysB.monkeysC.monkey()2.Thepighasfour________.A.footB.feetC.foots　　()3.Mytwobrothersare________.A.policemanB.policemansC.policemen()4.Icanseeten_____inthepicture.A.sheepB.dogC.pig　　()5.The_____hasthree_____.A.boys，watchesB.boy，watchC.boy，watches　　()6.Canyousee_______ontheplate?A.breadB.breadsC.breades　　()7.Thegirloftenbrushesher_____beforeshegoestobed.A.toothB.toothsC.teeth　　()8.Mr.Blackoftendrinksome_________.A.milkB.milksC.milkes　　()9.Therearesome_____onthefloor.A.childB.manC.books　　()10.Lucywillhassome_______.A.photoB.photosC.photoes()11.Iamdrinkingtwo________.A.cupsofwaterB.cupofwaterC.cupsofwaters　　()12.Thecateatstwo_______onMonday.A.mousesB.miceC.mouse　　()13.Ineedapenandsome_____.A.booksB.deskC.chair()14.Thereare______intheroom.A.photosB.photoesC.photo　()15.Thereissome_____intheriver.A.fishB.fishesC.fishs　　()16.There___two___inthebox.A.iswatchB.arewatchesC.arewatch()17.Wehavetoclean___everyday.ourtoothB.ourtoothsC.ourteeth()18.My_____roomisnexttothereadingroom.A.teacherB.teacher’sC.teachers　　()19.TomandJimare______.A.friendsB.friendC.brother　()20.Howmany_____dotheyhave?A.pictureB.picturesC.apicture　四写出下列名词复数形式。1．bag_______     2．orange_______    3．family_______ 4．wish_______    5．shelf_______     6．knife_______ 7．key_______     8．baby_______     9．tooth_______ 10．foot_______   11．woman_______    12．sheep_______ 13．Japanese_______ 14．potato_______ 15．radio_______  16．child_______    17．fish_______ 18．photo_______ 19．Frenchman_______ 20．mandoctor_______ 21.watch_______ 22.bus_______ 23.sheep_______ 24.foot_______  五选取填空1.Theycomefromdifferent______A.countryB.countriesC.acountryD.countrys2.Howmany______doyouseeinthepicture?A.tomatosB.tomatoesC.tomatoD.thetomato3.Theyare______.A.womanteachersB.womenteachersC.womenteacherD.womanteacher4.Wouldyoulike_______,please?A.twoglassofwaterB.twoglassesofwaterC.twoglassofwatersD.twoglassesofwaters5.Mostof______livein_______.A.Germans，GermanB.German，GermenC.Germen，GermanyD.Germans，Germany6.Therearesome______inthese_______.A.knifes…pencil-boxesB.knives…pencils-boxC.knives…pencil-boxD.knives…pencils-boxes7.______like______byair.A.Greens，travellingB.TheGreen，travelingC.TheGreens，travelD.TheGreens，traveling8.Iwonderwhy______areinterestedinactionfilms(武打片).A.thepeopleB.peopleC.peoplesD.thepeoples9.Thereisno______intheplate.A.applesB.orangesC.riceD.eggs10._______ aregoodforourhealth.A.TomatosB.TomatoesC.Tomato11.______and______arenotfriends.A.Foxs…wolfsB.Foxes…wolfsC.Foxes…wolves12.Thesearethe______ofour
