七年级英语单数复数专项练习题合集

七年级英语单数复数专项练习题合集名词的单数与复数是英语语法的基础模块，也是七年级英语学习的重点之一。准确掌握名词复数的变化规则及用法，对于构建正确的句子、提升语言应用能力至关重要。以下这份专项练习题合集，旨在帮助同学们通过系统练习，巩固所学知识，熟练运用单复数形式。一、名词单复数规则回顾(BriefReview)在开始练习前，我们先来快速回顾一下名词复数的基本变化规则，这将有助于你更顺利地完成后续练习：1.一般情况：直接在名词词尾加-s。例如：book→books,cat→cats。2.以s,x,ch,sh结尾的名词：加-es。例如：bus→buses,box→boxes,watch→watches,dish→dishes。3.以"辅音字母+y"结尾的名词：变y为i，再加-es。例如：city→cities,baby→babies。（注意：以"元音字母+y"结尾的名词，直接加-s，如：boy→boys,toy→toys）。4.以f或fe结尾的名词：多数变f/fe为v，再加-es。例如：leaf→leaves,knife→knives。（部分特殊词直接加-s，如：roof→roofs,belief→beliefs，这类词需要特别记忆）。5.以o结尾的名词：*有生命的名词，通常加-es。例如：potato→potatoes,tomato→tomatoes。*无生命的名词，通常加-s。例如：photo→photos,radio→radios。（也有例外，需积累）。6.不规则变化：这类名词的复数形式没有固定规则，需要逐个记忆。例如：man→men,woman→women,child→children,foot→feet,tooth→teeth,mouse→mice,sheep→sheep,deer→deer,fish→fish(强调种类时可用fishes)。7.集合名词：有些集合名词本身即可表示复数意义，如：people(人们),police(警察)。二、专项练习题(Exercises)Exercise1:写出下列名词的复数形式(Writethepluralformsofthefollowingnouns)1.pen→______2.bag→______3.map→______4.girl→______5.boy→______6.class→______7.box→______8.brush→______9.watch→______10.dish→______11.family→______12.baby→______13.city→______14.country→______15.leaf→______16.knife→______17.wolf→______18.life→______19.potato→______20.tomato→______21.photo→______22.radio→______23.man→______24.woman→______25.child→______26.foot→______27.tooth→______28.mouse→______29.sheep→______30.fish→______Exercise2:用括号内所给名词的适当形式填空(Fillintheblankswiththecorrectformofthenounsinbrackets)1.Ihavetwo______(book)onmydesk.2.Therearemany______(child)playinginthepark.3.Mymotherboughtthree______(potato)andsome______(tomato)thismorning.4.Lookatthose______(sheep).Theyareeatinggrass.5.Hehasanew______(watch).Itlooksverynice.6.Howmany______(class)arethereinyourgrade?7.These______(woman)aredoctorsinthehospital.8.Ineedsome______(box)toputmybooks.9.The______(leaf)turnyellowinautumn.10.Myfatheroftenreads______(newspaper)afterdinner.Exercise3:选择填空(MultipleChoice)1.There______apenandtwopencilsonthedesk.A.isB.areC.amD.be2.Mybrotherhasthree______.A.toycarB.toyscarC.toycarsD.toyscars3.Howmany______doyouseeinthepicture?A.sheepB.sheepsC.sheepesD.asheep4.Thisismy______room.A.parentsB.parent'sC.parents'D.parents's5.Ilikeeating______.Theyaresweet.A.bananaB.bananasC.abananaD.bananos6.Therearefive______inourschool.A.manteacherB.menteacherC.manteachersD.menteachers7.Those______arered.A.appleB.anappleC.applesD.theapple8.Hebrusheshis______twiceaday.A.toothB.teethC.toothesD.tooths9.The______ofthehouseiswhite.A.roofB.roofsC.roovesD.roofes10.Therearemany______inthesky.A.cloudB.cloudsC.cloudesD.acloudExercise4:句型转换(SentenceTransformation)1.Thisisadog.(改为复数句)______are______.2.Thatisabox.(改为复数句)______are______.3.Heisachild.(改为复数句)______are______.4.Ihaveanewbook.(改为复数句)Wehave______new______.5.Thisisanapple.(改为复数句)______are______.6.Thesearebuses.(改为单数句)______isa______.7.Thosearewomen.(改为单数句)______isa______.8.Theyaremyfriends.(改为单数句)______ismy______.Exercise5:改错(ErrorCorrection)(找出句中名词单复数错误并改正)1.Therearetwobookonthetable.______→______2.Ihavethreechild.______→______3.Shelikestoeattomato.______→______4.Themanteachersareverykind.______→______5.Myfootsarebig.______→______6.Wehavemanynicetoy.______→______7.Thosesheepsareeatinggrass.______→______8.Hehasfiveboxs.______→______9.Thegirlisplayingwithtwobaby.______→______10.Thereissomeappleontheplate.______→______三、参考答案(ReferenceAnswers)Exercise1:1.pens2.bags3.maps4.girls5.boys6.classes7.boxes8.brushes9.watches10.dishes11.families12.babies13.cities14.countries15.leaves16.knives17.wolves18.lives19.potatoes20.tomatoes21.photos22.radios23.men24.women25.children26.feet27.teeth28.mice29.sheep30.fish/fishesExercise2:1.books2.children3.potatoes,tomatoes4.sheep5.watch6.classes7.women8.boxes9.leaves10.newspapersExercise3:1.A2.C3.A4.C5.B6.D7.C8.B9.A10.BExercise4:1.These,dogs2.Those,boxes3.They,children4.some/many,books5.These,apples6.This,bus7.That,woman8.He/She,friendExercise5:1.book→books2.child→children3.tomato→tomatoes4.man→men5.foots→feet6.toy
