模块八:数词(一)概说:英语的数词可分为基数词和序数词两大类。基数词表示的是人或事物的个数,而序数词表示的是这些数目的顺序。1.基数词:表示数目的词称为基数词,下面是最常用的基数词:1one11eleven2two12twelve20twenty3three13thirteen30thirty4four14fourteen40forty5five15fifteen50fifty6six16sixteen60sixty7seven17seventeen70seventy8eight18eighteen80eighty9nine19nineteen90ninety10ten100one(a)hundred百1000one(a)thousand千10000tenthousand万100000one(a)hundredthousand十万1000000one(a)million百万2.序数词:序数词表示事物的顺序,往往与定冠词the连用。常用的序数词如下:序数词缩写序数词缩写firstsecondthirdfourthfifthsixthseventheighthninthtentheleventhtwelfth1st2nd3rd4th5th6th7th8th9th10th11th12thtwentiethtwenty-firstthirtieththirty-fifthfortiethfiftiethsixtiethseventietheightiethninetiethhundredth20th21st30th35th40th50th60th70th80th90th100th基数词变序数词口诀:基变序很容易,结尾加上th,一二三特殊记,结尾各是t.dd,(firstsecondthird)八去t,九去e,f来把ve替,y改ie结尾仍有th,若是遇到几十几,只变个位就可以,(二)数词的某些用法:1、表示计量:表示事物的计量,即事物的长度、宽度、深度和高度,应采用基数词。如:Itis50metres/kilometers/mileslong(wide,deep,high).它有50米/千米/英里长(宽、深、高)。2、表示编号:编号的数字如果过小,可用序数词或基数词表示;如果数字较大,通常用基数词表示。如:Thetenthlesson=LessonTen 第10课Room405 第405号房 Page215 第215页No.14MiddleSchool 第14中学TelephoneNO.5855806 电话:5855806【重点】3、表示不确切的数字:基数词后面直接加上复数名词表示精确的数字,而基数词复数形式加上“of”表示不确切的数字。如:fivehundredstudents 500名学生twothousandpeople 2000人 5打铅笔hundredsofstudents 几百名学生millionsofworkers 成千上万的工人4、表示年龄和岁数1)表示年龄的主要句式如下:Heisaboyof10yeasold. 他是个10岁的男孩子。Heis10yeasold. 他10岁。Attheageoften,hebegantolearnEnglish. 他10岁开始学英语。Heis10(yearsofage). 他10岁。Heisaten-year-oldboy. 他是个10岁的男孩子。2)介词in+one’stwenties(thirties…)表示“在某人20多岁(30多岁……)”。如:Myfatherisinhisfifties. 我爸爸50多岁。Whenhewasinhisforties,hebegantolearnEnglish. 当他40多岁时,他开始学英语。【难点】5、表示年代:表示什么世纪,什么年代时,通常在数词后加s或’s,并在年代前加定冠词the,如1980’s(20世纪80年代),读作:nineteeneighties.如: Hisgrandfatherdiedinthe1970’s。 他爷爷死于20世纪70年代。【重点】6、表示分数:分数的表达方式是:分子用基数词,分母用序数词。分子是one时,分母不必加s;分子大于one时,分母要加s.如:a(=one)third 三分之一 onefifth 五分之一twothirds 三分之二 threefourths 四分之三Twothirdsofthetreeswerecutdowntheyearsago.10年前三分之二的树木被砍伐了。 7、表示百分数:百分数的表达方式是:基数词+percent(单数形式)+of+名词。如:Thirtypercentofthestudentsinmyclassarefromcities. 我班30%的学生来自城市。About61percentofthesurfaceiscoveredbywater. 大约61%的表面被水覆盖着。8.时间和钟点如:6:15读作:sixfifteen/aquarterpastsix4:30读作:fourthirty/halfpastsix6:35读作:sixthirty-five/twenty-fivetoseven9:10a.m读作:ninetena.m.9:数字运算表达【基础题】()1.Thereare______daysinayear.A.threehundredssixty-fiveB.threehundredsandsixty-fiveC.threehundredandsixty-fiveD.threehundredandsixtyfive()2.Thereare______studentsinthisschool.A.eighthundredsandforty-sixB.eighthundredandfortysixC.eighthundredandforty-sixD.eighthundredforty-six()3.______peoplevisitthismuseumeveryday.A.HundredB.HundredsC.HundredofD.Hundredsof()4.Therearetwo______peopleinthemeetingroom.A.hundredB.hundredsC.hundredsofD.hundredof()5.Everyyear______watchNBAonTV.A.millionpeopleB.millionsofpeopleC.millionspeopleD.millionofpeople()6.______treeshavebeenplantedinourschoolinthepast10years.A.ThousandsofB.TwothousandsC.ThousandofD.Twothousandof()7.Look!Thereare______inthesky.A.thousandstarsB.thousandofstarsC.thousandsofstarsD.thousandsofstar()8.Mybrotherisin______.A.ThreeClass,OneGradeB.ClassThree,GradeOneC.GradeOne,ClassThreeD.classthree,gradeone()9.Wearegoingtolearn______thisterm.A.booksixB.sixbookC.thebooksixD.BookSix()10.Pleaseturnto______.Let'sreadthetextaloud.A.PageTwoB.thepagetwoC.secondpageD.pagesecond【提高题】I.选择题1.Thereare_________daysinayear.A.threehundredandsixty-fiveB.threehundredsixtyfiveC.threehundredssixty-fiveD.threehundredsandsixty-five2.Oh,it's._________.Let'sgotoschooltogether.A.thequartertoeightB.aquartertoeightC.sevenforty-fiveminutesD.forty-fivepastseven3.Schoolusuallybeginson_________.A.thefirstofSeptemberB.thefirst,SeptemberC.SeptemberOneD.September,thefirst4.TheOlympicGameswillbeheldinAustraliain_________.A.2,000yearB.theyear2,000C.the2,000D.theyearof2,0005.I'mafraid_________ofthestoiyisnotsointeresting.A.theparttwoB.secondpartC.thesecondpartD.partsecond6.—Whichroomareyoustayingin?—_____.A.TheRoom301B.301RoomC.Room301stD.Room3017.—Howmanytypewritersdoyouneed?—Ineed________.A.threeonesB.threeC.thethreeD.themthree8.About_________saidthattheyenjoyedthosebooksverymuch.A.fourfifthsstudentsB.fourfifthofthestudentsC.fourfifthsofstudentsD.fourfifthsofthestudents9.—Howmuchdoestheparcelweigh?—Justaminute.I'llweighit.Itweighs________.A.oneandhalfakilogrammeB.oneandahalfkilogrammeC.onekilogrammeandhalfD.onekilogrammeandahalf10.—Howsoonwillyoufinishtypingtheletter?—______.A.oneortwominuteB.oneminuteortwoC.aminuteortwoD.aortwominutes11.We'llspendthesummerholidaysinthemountain_______milesaway.A.severalhundredsB.hundredsofC.severalhundredofD.hundredof12.—Hemustbe________.—Yes,he'sstillstronglikeayoungman.A.inhissixtiesB.inhissixtyC.oversixtiesD.sixty-year-old13.As_______customerofthesupermarket,MrLiwasgivenanicepresent.A.athousandB.thethousandthC.thethousandsD.thousandth14.Threestudentsofourclasshavebeenchosenthetopstudentsoftheyear.AndIamoneof.A.threeB.thethreeC.thirdD.thethird15.—Haveyoufoundthesixcoinsyoulostyesterday?—Ihavefound_______,butIcan'tfind____.A.five,thesixthB.five,sixC.fifths,sixD.fifth,sixth16.NextSundaywillbeJane's_______.birthday.A.thirty-ninthB.thirtieth-ninthC.thirtieth-nineD.thirty-nine17.We'llhavetoenterthestadiumat.___.A.theGateFourB.GateFourC.FourthGateD.GateFourth18.My_________daughterlikestoaskquestionsaboutanythingshesees.A.six-years-oldB.sixyearsoldC.six-year-oldD.six-yearold19.—What'son.............?—Sorry,Idon'tknow.WhynotlookitupinTVGuide?A.Channel20B.20ChannelC.Channel20thD.20thChannel20.TheYellowRiveris_longestriverinChina.A.twoB.thetwoC.thesecondD.second21.Wehavetwocomputerrooms.Stillwearegoingtobuild______one.A.thethirdB.athirdC.threeD.thethree22.AngelknowsalotaboutChinaasshehasbeentoChina.............A.forthefourthtimeB.fourtimesC.afourthtimeD.forfourtimes23.Inthepast..................,Shanghaihaschangedalot.A.threeyearsB.thirdyearC.three-yearD.third-year24.Acentisofadollar.A.thehundredthB.onehundredthC.ahundredD.thehundred25.Tomysurprise,themachinewasinventedbyahighschoolstudentof_______.A.fifteen-year-oldB.fifteenC.fifteen-yearageD.ageoffifteen26._________isnotalways________best.A.Fist,theB.Afirst,aC.Thefirst,theD.First,/27.Thestoresells_________dressesamonth.A.severalthousandB.severalthousandsC.severalofthousandD.severalthousand28.Over_________poundshavebeenraisedforthepoorchildrenthere.A.fourmillionB.fourmillionofC.fourmillionsD.fourmillionsof29.Whatworkareyougoingtogive_______?A.ustwoB.twousC.thetwousD.theustwo30.Shereceivedavideocameraforher_________birthday.A.fourteenB.thefourteenthC.fourteenthD.fourteen's31.Irememberthat_________ofthemonthwasaholidayandIdidn'tgotowork.A.thirdB.threeC.onethirdD.thethird32.I'veaskedhertwice.ShallIaskher_________?A.athirdtimeB.threetimesC.thirdtimeD.thethirdtime33._________ofthemachinesonshowarenewitems.A.TwofifthB.TwofifthsC.ThetwofifthD.Twofive34.Onlyfivestudentsclimbedtothetopofthehill.Iwas______.....A.afifthB.fifthC.thefiveD.thefifth35.Thebottlewasabout_________fullthen.A.three-quartersB.threequarterC.thirdquarterD.thirdquarters36.ChristmasDayison_________eachyear.A.December,25B.25thofDecemberC.theDecember25D.the25thofDecember37.Ithink_________istheworstpartofthepl
