初中数词专项练习题大全

初中数词专项练习题大全一、数词知识要点回顾在开始练习之前，我们先来简要回顾一下数词的核心知识点，这将有助于你更高效地完成后续练习。1.基数词(CardinalNumbers):表示数量的多少，如one,two,three...百(hundred),千(thousand),万(tenthousand),百万(million),十亿(billion)等。注意“百、千、百万”等词与具体数字连用时不加复数词尾“s”，如twohundred(而非twohundreds)；但若表示不确定的泛指数，则需加“s”并与“of”连用，如hundredsofpeople。2.序数词(OrdinalNumbers):表示顺序或等级，如first,second,third...通常由基数词加词尾“-th”构成，但也有特殊变化，如fifth,eighth,ninth,twelfth等。序数词前通常要加定冠词“the”。3.分数(Fractions):由基数词和序数词组合而成。分子用基数词，分母用序数词。分子大于一时，分母要用复数形式。如1/3(onethird),2/5(twofifths)。4.小数(Decimals):小数点读作“point”，小数点前后的数字分别读出。如3.14(threepointonefour)。5.百分数(Percentages):用“基数词+percent”表示，如50%(fiftypercent)。6.倍数(Multiples):常用“基数词+times”表示，如twice(两倍),threetimes(三倍)。7.概数(ApproximateNumbers):表示不确定的数量，如dozensof,scoresof,hundredsof,thousandsof等。二、专项练习题（一）基数词专项练习A.单项选择1.Thereare______daysinaweek.A.fiveB.sixC.sevenD.eight2.Myfatheris______yearsold.(假设一个合理的两位数，如四十多，这里用forty-five)A.fortyfiveB.forty-fiveC.fourty-fiveD.fourtyfive3.Thereareabout______studentsinourschool.(假设一个三位数，如五百多，这里用fivehundred)A.fivehundredsB.fivehundredC.fivehundredsofD.hundredof4.—Howmanybooksdoyouhave?—Ihave______.A.twodozensB.twodozenC.twodozenofD.dozens5.Thereare______peopleinthehall.It'sverycrowded.A.hundredofB.hundredsC.hundredsofD.hundredB.用括号内所给基数词的适当形式填空6.Thereare______(twelve)monthsinayear.7.MybrotherisinGrade______(three)thisyear.8.Thisbuildinghas______(twenty)floors.Iliveonthe______(five)floor.(此题兼考序数词，为后续练习铺垫)9.Thereare______(thirty)daysinApril.10.—What'sthreeandfive?—It's______(eight).（二）序数词专项练习A.单项选择1.Septemberisthe______monthoftheyear.A.nineB.ninthC.ninethD.thenine2.—Whichfloordoyouliveon?—Iliveonthe______floor.A.twelveB.twelvethC.twelfthD.thetwelfth3.Thisismy______timetovisitBeijing.A.oneB.firstC.thefirstD.once4.Children'sDayisonthe______ofJune.A.oneB.firstC.1thD.1st(注意缩写形式的正确写法)5.Hewasthe______tofinishtherace.A.threeB.thirdC.three-thD.thirdlyB.根据所给基数词写出相应的序数词及其缩写形式6.one→______(______)7.two→______(______)8.three→______(______)9.five→______(______)10.eight→______(______)11.nine→______(______)12.twelve→______(______)13.twenty→______(______)14.thirty-one→______(______)15.forty→______(______)（三）分数、小数与百分数专项练习A.用英语写出下列分数、小数或百分数1.1/2→______2.3/4→______3.2/5→______4.1/3→______5.0.5→______6.3.14→______7.2.5→______8.10%→______9.50%→______10.75.5%→______B.单项选择11.______ofthestudentsinourclassareboys.A.TwothirdB.TwothirdsC.SecondthirdD.Secondthirds12.Onethirdofthecake______eatenbyTom.A.wasB.wereC.isD.are13.Thepriceofthebookis______yuan.A.fifteenpointsixB.fifteenpointssixC.fifteenandsixD.fifteenpointsixth14.About______oftheearth'ssurfaceiscoveredwithwater.A.seventypercentsB.seventypercentC.seventiethpercentD.seventiethpercents（四）倍数与度量专项练习A.用括号内所给词的适当形式填空1.Thisroomis______(two)asbigasthatone.2.TheYangtzeRiverisoneofthe______(long)riversintheworld.(此句虽含序数词含义，但主要考形容词最高级，可调整或保留以综合考查)3.Thepopulationofthiscityis______(three)timeslargerthanthatofourtown.4.Thetreeisabout______(five)meterstall.5.Thisboxis______(twice)heavierthanthatone.B.单项选择6.Thenewbridgeis______theoldone.A.threetimeslongasB.threetimesaslongasC.asthreetimeslongasD.threetimeaslongas7.Myschoolbagis______yours.A.twiceheavythanB.twiceasheavierasC.twiceheavierthanD.astwiceheavyas8.Thestreetisabout______meterswide.A.fiftyB.fivetyC.fiftiethD.thefiftieth（五）概数表达专项练习A.单项选择A.hundredofB.hundredsC.hundredsofD.hundred2.Hehas______booksinhisstudy.A.twohundredofB.twohundredsC.twohundredD.hundredof3.______birdsareflyinginthesky.A.DozenofB.DozensC.DozensofD.Adozenof4.I'vetoldyou______timesnottodothat.A.scoreB.scoresC.scoreofD.scoresofB.用括号内所给词的适当形式填空6.Hebought______(dozen)ofeggsyesterday.7.Thereare______(hundred)ofstarsinthesky.（六）综合填空用适当的数词填空，使句子完整通顺。1.Mybirthdayisonthe______(8)ofMarch.2.Thereare______(7)continentsintheworld.4.—What'sthetime?—It's______(9:15).(aquarterpastnine/ninefifteen)5.About______(30)percentofthestudentslikeplayingbasketball.7.TheGreatWallismorethan______(6000)kilometerslong.(此处数字超过四位，仅为举例，实际练习可调整为threethousand)8.PleaseturntoPage______(25).9.Shegot______(90)pointsintheEnglishtest.10.______(2/3)oftheworkhasbeenfinished.三、参考答案（一）基数词专项练习A.单项选择1.C2.B3.B4.B5.CB.用括号内所给基数词的适当形式填空6.twelve7.Three8.twenty,fifth9.thirty10.eight（二）序数词专项练习A.单项选择1.B2.C3.B4.B5.BB.根据所给基数词写出相应的序数词及其缩写形式6.first(1st)7.second(2nd)8.third(3rd)9.fifth(5th)10.eighth(8th)11.ninth(9th)12.twelfth(12th)13.twentieth(20th)14.thirty-first(31st)15.fortieth(40th)（三）分数、小数与百分数专项练习A.用英语写出下列分数、小数或百分数1.onehalf/ahalf2.threequarters/threefourths3.twofifths4.onethird5.zeropointfive/pointfive6.threepointonefour7.twopointfive8.tenpercent9.fiftypercent10.seventy-fivepointfivepercentB.单项选择11.B12.A(
