Grammar1名词分类:2可数名词有单数和复数两种形式。指一个人或一件事物时,用单数形式;指两个或多个人或事物时用复数形式。可数名词复数的规则变化:1.一般的名词词尾直接加-s。如:book→booksroom→roomshouse→housesday→days2.以s,x,ch,sh结尾的名词,在词尾加-es。如:bus→busesbox→boxeswatch→watchesdish→dishes33.以辅音字母+y结尾的名词,要先将y改为i再加-es。如:city→citiesbody→bodiesfactory→factories4.以o结尾的名词,通常有生命的加es无生命的加s。如:Negroesandheroeslikeeatingtomatoesandpotatoes.黑人英雄爱吃土豆西红柿。(以“O”结尾表示有生命的名词)piano→pianosradio→radiosphotophotos(以“O”结尾无生命的名词)45.以f或fe结尾的名词,要将f或fe改为v再加-es。如:half→halvesleaf→leavesknife→kniveswife→wives6.可数名词复数的不规则变化:男人女人a变e,man→menwoman→women鹅足牙oo变ee,goose→geesefoot→feettooth→teeth老鼠虱子也好记,ous变ic,mouse→micelouse→lice孩子加上ren,鱼鹿绵羊不用变。child→childrenfish→fishdeer→deersheep→sheep5如果普通名词所表示的事物是不能按个数来计算的,这类名词就叫不可数名词。不可数名词分:1.为物质名词(表示无法分为个体的物质,如:meat,rice,water,milk,orange橘汁)2.抽象名词(表示动作、状态、情况、品质等抽象概念,如:work,homework,time,health,friendship)。61.不可数名词没有复数,当它作句子的主语时,谓语动词要用单数形式。如:Thefoodisveryfresh.食品很新鲜。2.有的不可数名词也可以作可数名词,有复数形式,但他们的意义往往发生变化。如:water(水)→waters(水域)orange(橘汁)→oranges(橘子)73.很多的不可数名词表示泛指时为不可数,表示种类时就可数,但意义大多不发生变化。如:fruit→fruits(果类食物)food→foods(食品)fish→fishes(鱼类)hair→hairs(体毛;几根头发)最常见的不可数名词有:baggage,change(零钱),furniture,hair,homework,information,knowledge,luggage,money,news,progress,traffic,beef,mutton,broccoli,orange(橘子,橘子汁,橙色)8特殊类型:1.有些名词既可作可数名词,又可作不可数名词如:advice劝告;消息、报告cake蛋糕chocolate巧克力fish鱼、鱼肉chicken鸡、鸡肉92.用在不可数名词前的量词词组的单复数变化如:abottleofink一瓶墨水twobottlesofink两瓶墨水3.用在不可数名词前的量词词组要按英语的习惯与不可数名词搭如:apieceofmeat一块肉apieceofpaper一张纸abarofchocolate一块巧克力1011一、写出下列名词的复数形式1.orange2.class3.monkey4.piano5.child6.shelf7.bed8.country9.family10.toy11.foot12.radio13.photo14.tomato15.woman16.knife17.sheep18.ship19.dish20.mouseorangesclassesmonkeyspianoschildrenshelvesbedscountriesfamiliestoysfeetradiosphotostomatoeswomenknivessheepshipsdishesmice122)选择填空1.Theycomefromdifferent______.A.countryB.countriesC.acountryD.Countrys2.Howmany______doyouseeinthepicture?A.tomatosB.tomatoesC.tomatoD.thetomato3.Therearesome______inthese_______.A.knifespencil-boxesB.knivespencils-boxC.knivespencil-boxD.knivespencils-boxes4.Thereisno______intheplate.A.applesB.orangesC.riceD.Eggs5._______aregoodforourhealth.A.TomatosB.TomatoesC.Tomato136.Iliketoeatcakewith______.A.cherriesB.cherryC.cherrys7.______and______arenotfriends.A.FoxswolfsB.FoxeswolfsC.Foxeswolves8.Doyouwanttodrinksome_____?A.amilkB.milkC.milks9.Thisis_____room.It’sverybig.A.LilyandLucy’sB.Lily’sandLucy’sC.Lily’sandLucy10.Inautumnyoucanseealotof____ontheground.A、leafB、leafsC、leaves14三.选择正确的词形1.Howmany(radioes,radios)canyousee?2.Thereare36(boys,boies)inmyclass.3.Lookatthose(sheeps,sheep).4.Idon’twant(a,an)oldcup.5.Givemethat(box,boxes),please.154)请用括号中名词的复数形式填空1.Lookatthose.(child)2.Icanseeastandingnearthedoor.(policeman)3.Doyouwantsomefordinner?(potato)4.Inautumn,youcanseealotofontheground.(leaf)5.Hehastwo.Oneisblue,theotherisyellow.(box)6.Twoliveinthisbuilding.(family)childrenpolicemanpotatoesleavesboxesfamilies1617
