s.词尾读音shopshops(商店)在清辅音后读[s]bagbags(书包)在浊辅音后读[z]windowwindows(窗户)在元音后读[z]2.以s,x,sh,ch结尾的单词在词尾加es。classclasses(班级)词尾读音[iz]boxboxes(盒子)matchmatches(比赛)brushbrushes(刷子)3.以“辅音字母+y”结尾的词，变y为i加es.storystories(故事)词尾读音[iz]4.以“元音字母+y”结尾的词，在词尾直接加skeykeys词尾读音[z]monkeymonkeys5.以“o”结尾的名词，复数一般在词尾加“s”,但个别加“es”tomatotomatoes(西红柿)词尾读音[z]potatopotatoes(土豆)zoozoos(动物园)photophotos(照片)*（以“o”结尾，复数加“es”）口诀：黑人(Negro)英雄(hero)，左手拿着西红柿(tomato)，右手拿着破土豆(potato)，头顶一个大芒果（mango）。6.以f或fe结尾的词，多数变f或fe为ves.leafleaves(树叶)词尾读音[vz]knifeknives(小刀)*（以f或fe结尾的单词，需把f或fe变ves的单词）口诀：妻子（wife）持刀（knife）去宰狼（wolf），小偷（thief）吓得发了慌，躲在架下（shelf）保己命，半(half)片树叶（leaf）遮目光。*（以f或fe结尾的单词，直接加“s”的单词）口诀：长颈鹿(giraffe)站在屋檐(roof)下，左手拿着手绢(handkerchief)，右手拿着高尔夫球(golf)。例：roofroofs(屋顶)7.不规则名词复数的变化manmen(男人)toothteeth(牙齿)childchildren(儿童)mousemice(老鼠)footfeet(脚)womanwomen(女人)8.名词单复数形式一样sheepsheep(绵羊)deerdeer（鹿）EnglishEnglish（英国人）ChineseChinese（中国人）*（不规则名词变复数）口诀：男人，女人a变e；鹅，足，牙齿oo变ee；其实老鼠也好记ous变ic；孩子加上ren，鱼鹿绵羊不用记。二、名词所有格的构成法1.主要是在词尾加’s构成。如:ThisisTom’sdesk.这是汤姆的书桌。ThatisMike’sbook.那是迈克的书。2.如果原名词已经有复数词尾s,则仅加一个’.如:theteachers’readingroom教师阅览室thepupils’pencil-boxes学生们的文具盒3.如果原词是复数形式，但不是以s结尾，变为所有格形式需在后面加上’s。如：thechildren’spalace少年宫men’sroom男厕所*名词所有格口诀：名词所有格，s前面加一撇’，复数s放在尾，后加一撇就完结，两人共有算一个，后面只加一个撇。名词练习题写出下列名词的复数形式_____________________________________________________________________________________________________________________________________________________________________________________________________________18.life______________19.story__________________________21.baby_______________________________________24.deer_______________________________________28.English____________30.man_____________二、汉译英1．Tom的足球_________________2.老师们的自行车_________________3．学生们的课桌_________________4.哥哥的文具盒_________________5．姑姑的卡片_________________6.猴子们的香蕉_________________7．蚂蚁们的早餐_________________8.妈妈的包_________________9．姐姐的连衣裙_________________10女孩们的苹果_________________三、把下列句子翻译成英文1．这些是Peter的篮球吗________________________________________2．这个是老师的钢笔吗___________________________________________3．有一些书在Sam的课桌上。________________________________________4．有一些孩子们在教室里。___________________________________________四、改错（圈出错处，在横线上改正过来）aresomebutterflysonthetable.________________________isAlicedress.______________________liketomatoverymuch.__________________五、将下列句子变成复数形式。1．Thisdogisbrown.___________________________________________________2.Thereisabookandapenonthetable.___________________________________________________womanisateacher.___________________________________________________能力测试卷（名词）将下列名词变成复数形式。treelessonmonthappleshirt2.boxbusbrushwatchclassfoxlifeleafWifethiefboymonkeybabycountrystoryradiopianotomatohero6.childtoothmanSheepEnglishChinese二、判断正误，并改正错句，正确的打“√”1．Thehouseismybrother.________________________2.Hehasvisitedmanycountry.______________________3.TheyareEnglishs.______________________________4.ThisisTomredbike.____________________________三、选择填空1．Therearetwo______intheroom.A.ChinesesB.Englishmanoldmanwillhave___________out.A.twotoothsB.twoteeth3.____________aresoldinthisbookstore.A.Children’sbooksB.Childrenbooks4.Somefriendsof_________willcomehere.A.John’sB.John5.Canyougiveme______________A.somepapersB.apieceofpaperare______________onthefloor.A.someboxB.someboxes四、将下列句子变成复数形式。1．Thissheepiswhite.___________________________________________________2.Thereisadeskandachairintheroom.___________________________________________________manisadoctor.___________________________________________________第二章代词一、人称代词1．人称代词即表示“你、我、他、你们、我们、他们”等的词，它的人称、数和格的变化见下表：数人称主格宾格单数第一人称Ime第二人称youyou第三人称hesheithimherit复数第一人称Weus第二人称youyou第三人称theythem主格与宾格：人称代词有主格和宾格两种形式。主格主要用来做句子的主语；宾格主要用作宾语。人称代词主格用在句首作主语。Sheissittinginabus.她正坐在公共汽车上。人称代词宾格在动词后作宾语。Thispeniscan’twritewithit.这支钢笔不好，我没法用它写字。2.人称代词的排列顺序人称代词并列使用时，通常以下列顺序出现，请熟悉并记忆。单数代词：youandI;youandhe;heandI;you,heandI复数代词：weandthey;weandyou;youandthey;we,youandthey第三人称单数代词：heandshe*人称代词排序口诀：人称代词并列观，注意顺序礼貌见；单数人称二、三、一，复数人称一、二、三；麻烦事情“我”站前，其他人称没意见；两性并用为三单，男先女后是习惯。二、物主代词物主代词是表示所有关系的代词，分为形容词性物主代词和名词性物主代词。人称类别第一人称第二人称第三人称单数复数单数复数单数复数形容词性myouryouryourhis,her,itstheir名词性mineouryoursyourshis,hers,itstheirs名词性物主代词=形容词性物主代词+名词例，Whosecoatisthis这是谁的上衣It’shers.是她的。hers=hercoat*关于物主代词的口诀：物主代词很重要，译成汉语都有“的”，后面必须加上物，否则就要犯错误，myyourhisheritsourtheir不放过。形容词性是基础，除了我的

“mine”外，其他词尾“s”性形物代能力差，出门常把名词加；名物代能力强，常来独去又独往。三、反身代词反身代词也叫“自身代词”，表示“**自己”。数人称第一人称第二人称第三人称单数myselfyourselfhimself,herself复数ourselvesyourselvesthemselvesIcandoitbymyself.我自己能做这件事。*反身代词的构成规律记忆口诀：反身代词有规律，第三人称宾格加，其余开头用物主，复数-ves替-f四、指示代词This(这个)these(这些)指近处的事物That(那个)these(那些)指远处的事物例，Thisisabook.这是本书。Thesearesomebooks.这些是书。Thatisacar.那是辆小汽车。Thosearesomecars.那些是小汽车.代词练习题根据题意，用所给词的适当形式填空。Maryisafriendof______________.(I)Thisis________(she)ruler.________(I)isinthebag.Herbrotheristooyoungtolookafter_________(he)Thisis_________(I)book.Thisbookis_________(I).Thesepensare_________(we).二、填写下列表格。人称代词我我们你，你们他她它他们主格宾格形容词性物主代词名词性物主代词反身代词三、改写下列句子Eg,Thisismybook.Thebookismine.Thatisherruler._________________________________Thesearetheirfootballs.__________________________________Thisismybackpack.____________________________________Thoseareyourboxes.____________________________________四、把下列句子改写成复数。1.Thisisabutterfly.____________________________________________2.Thatisabus.________________________________________________3.Itisamouse.________________________________________________五、改错。isminelamp.___________________________________________areours3.Thataretheirteacher.___________________________________________houseismybrother.________________________5.Hehasvisitedmanycountry.______________________6.TheyareChineses.______________________________7.ThisisTomredbike.____________________________能力测试卷（代词）帮下面的好朋友团圆（连线）I她its我们her他（她，它）们we我they你的their他（她，它）们your她的she它的二、填空1．She’sateacher.Thisis_________bag.2.He’sadriver.Thisis___________taxi.3.Iamaboy.__________nameisPeter.4.--What’s__________name--MynameisTony.5.It’smypuppy.______nameisMimi.三、选择()bookisnotsooldas_________.A.himB.heC.hisD.she()2._____bookisitIt’s________.A.Whose…herB.Whose…hersC.Who…hersD.Whom…her()3.Heisafriendof________.A.ourB.usC.myD.mine四、改错1.I,youandheareallteachers.______________________________________________________2.Thisismineteddybear.______________________________________________________3.Theseareoursbags.______________________________________________________4.Theseistheirteachers.______________________________________________________第三章数词和冠词一、数词表示数目和顺序的词叫数词。数词又分基数词和序数词，基数词表示数量，序数词表示顺序。最基本的基数词如下表所示：1~1011~1920~1001one11eleven2two12twelve20twenty3three13thirteen30thirty4four14fourteen40forty5five15fifteen50fifty6six16sixteen60sixty7seven17seventeen70seventy8eight18eighteen80eighty9nine19nineteen90ninety10ten100onehundred*基数词的写法：21~99的两位数，十位与个位之间用连字符“-”。例：21twenty-one32thirty-two99ninety–nine百位数：个位数基数词形式加“hundred”，表示几百，在几十几与百位间加上and。例：101ahundredandone.320threehundredandtwenty648sixhundredandforty-eight2．序数词的构成1）一般来说，是由相应的基数词加词尾th构成。例，four+thfourthsix+thsixthseven+thseventhten+thtenth2）下面这些基数词在变为序数词时，有特殊的变化。例，onefirsttwosecondthreethirdfivefiftheighteighthnineninthtwelvetwelfth3）十位整数序数词的构成方法是将基数词的词y变成i，然后在加eth.例，twentytwentieththirtythirtiethfortyfortiethninetyninetieth两位或两位以上的基数词变为序数词时，仅将个位数变成序数词。例，twenty–onetwenty-firstthirty-fivethirty-fifthahundredandfifty-threeahundredandfifty-third*基数词变序数词的口诀：基变序，有规律；词尾加上th（fourth,sixth）一、二、三，单独记；结尾字母t,d,d；（first，second，third）八去t,九去e,（eighth，ninth）；ve要用f替；（fifth，twelfth）整十基数变序数，ty将y变成i;th前面有个e；要是遇到几十几，前用基来后用序。二、冠词冠词分不定冠词和定冠词两种。a或an是不定冠词，the是定冠词。a用在辅音音素之前，如adesk,atree;an用在元音因素之前，如anapple,anhour,anEnglishbook.不定冠词（a,an）指人或事物的某一种类，表示“一个”，但不强调数量。Sheisateacher.That’sanorange.定冠词the，是特指某（些）人、某（些）物，或指说话人与听话人彼此知道的人或物，或者是在上文提到过的人和事。Thisisabus.Thebusisbig.不用冠词的情况：专有名词，物质名词，抽象名词前一般不用冠词。如，Chinese,English,Jim等。名词前已经有this,that,my,your等词时，就不再用冠词了。如，thatmouse(那只老鼠)3)一些固定词组前不用定冠词。如，athome在家gotoschool去上学*定冠词the的用法记忆口诀：特指、重提和唯一，岛屿、海峡和海湾；海洋、党派、最高级，沙漠、河流与群山；方位、顺序和乐器，年代、团体与机关；船名、建筑和组织，会议、条约与报刊；姓氏复数、国全名，记住定冠the加在前。*零冠词用法口诀：月份、星期、节假洲，呼语、头衔职务前；三餐、球类、惯用语，学科、棋类名词前。冠词和数词专项练习一、在空白处填上适当的冠词，不需要的填“/”。1)at____home2)goto_____bed3)goto_____school4)catch______badcold5)have_____goodtime6)______redapple7)_____Englishbook8)______spoon9)_____orange10)______melon11)_______eraser二、选择填空is_____“m”intheword“primary”anD./is____orangebike.D/alwaystakesushalf_____hourtohave____longwalkaftersupper.,aB,a,the,a,theis____usefullanguagein____world.,the,the,/D./,thearegoingto_____cinemathisevening.B./C/a’sstandingon_____othersideof_____river.,a,the,a,thepotatoisavegetable,not____fruit.,an,a,the,/was_____firsttocome.D./yousee____bookon_____table,a,an,an,the’s_____deskIt’sin____middleoftheroom.A./,/B./,a,/,theis_____friendofmine.B./is____universitynearthefarm.D./diedin____autumnof1989.A./have____book.It’s_____interestingone.Ilikereading____booksverymuch.,an,/,/,the,an,theD./,an,/is_____Children’sDay.D/is_____bag.Thatis____eraser.,a,an,aD.an,an四、用代词填空:,_____and____areallgoodfriends.,you,they,they,we,they,you,you,weclassroomisbig,but____ismuchbiggerthan_____.,they,us,their,our,theirs,ours,theirs,welost____pen.Willyoulendher____,yours,your,you,yourself4.“Whatareyoudoing”“Iamlookingat_____inthemirror”,____and_____allenjoymusic.,you,I,she,you,she,I,you,she能力测试卷（冠词和数词）写出相邻的数词1.twenty2.five3.twelve4.fifty-eight5.ninety6.seventy7.thirty-eight8.onehundred9.onethousand10.one二、选择正确答案areda
