数词数词分为基数词和序数词两种。表示数目或数量多少的词叫基数词；表示数目顺序的词叫序数词。一.基数词1.基数词就注意以下几点：（1）几十几的基数词的十位数与个位数之间要用连字符“-”连接。如：eighty-five85twenty-six26（2）三位数的基数词须在百位和十位（若无十位则和个位）之间用and连接。如：threehundredandsixty-five365twohundredandsix206（3）基数词的复数形式。当基数词hundred,thousand,million,billion等词前有具体数词或several修饰时，必须用单数。如：severalhundredyear’sago几百年前twothousandstudents两千个学生2.基数词的特殊用法：（1）表示“几十年代”或“几十岁”时，用逢十的基数词的复数形式。如：inthe1990’s20世纪90年代inone’stwenties在某人20多岁时（2）用在习语中。如：intwosandthrees三三两两地二.序数词序数词应注意的几点事项：1.多位数的基数词变成序数词时，只需将末位基数词变成序数词，前边的基数词不变。如：forty-two42forty-second第42nine-hundred900nine-hundredth第9002.当序数词用阿拉伯数字表示时，必须在数字后加上序数词的最后两个字母。如：21st第2132nd第323.序数词前一般要用定冠词the，如果序数词前用a或an时，则表示“又一；再一”（没有具体范围的限制）。如：Thoughhehadfailedtwice,hewantedtotryathirdtime.尽管他已失败了两次，他还想再试一次。Thelittlemonkeyhadhadthreeapples,andhewantedtoeatafourthone.那只小猴子已经吃了3个苹果，他还想再吃一个。三.分数和百分数1.分数（1）分数的分子用基数词，分母用序数词。如：onefifth五分之一onetenth十分之一（2）当分子大于1时，分母用序数词的复数。如：twothirds三分之二fiveeighths八分之五（3）当分子是1时，可以用one也可以用a。如：asecond=onesecondathird=onethird（4）当分母是2和4时，分别可以用half和quarter代替。如：1精品学习资料可选择pdf第1页，共6页-----------------------\nahalf二分之一threequarters四分之三2.百分数百分数用percent表示。如：fortypercent百分之四十threepercent百分之三3.分数、百分数与主谓一致分数、百分数的考查往往和主谓一致相联系。当分数、百分数修饰可数名词的复数时，谓语动词用复数形式；当分数、百分数修饰不可数名词时，谓语动词用单数形式。如：EightypercentofthestudentsinourschoolcomefromHenan.我们学校百分之八十的学生来自河南。ThreefourthsofthestudentsinmyclassareinterestedinEnglish.我们班四分之三的学生对英语感兴趣。Twothirdsofthewaterontheearthisseawater.地球上三分之二的水是海水。四.倍数的表示法1.表示“几倍大小（长短；数量）”，由“倍数+thesize（length,amount...）”结构组成。如：Theearthisforth-ninetimesthesizeofthemoon.2.表示“⋯⋯比⋯⋯大几倍”，由“倍数+形容词（副词）比较级+than+被比较部分”结构组成。如：Thisboxisthreetimesbiggerthanthatone.3.表示“⋯⋯是⋯⋯倍”，由“倍数+as+形容词+as+被比较部分”结构组成。如：Ourfactoryistwiceasbigastheirs.2精品学习资料可选择pdf第2页，共6页-----------------------\n数词()1.Lincolnwasbornon________.A.February12,1809B.1809,February12C.1809,12FebruaryD.February1809,12()2.A_______boycansingtheEnglishsongverywell.A.ten-year-oldB.tenyearsoldC.ten-year-oldD.fifthyearsold()3.Anhourlater,_____ministerwassenttoseethe“magiccloth”wovenbythosetwomen.A.twoB.thesecondC.thetwoD.second()4.AbrahamLincolnwas_______PresidentoftheUnitedStates.A.16B.the16C.16thD.the16th()5.Doyouthinkthereisanyroomforus________?A.twoB.thetwoC.secondD.thesecond()6.--Howmanystudentsarethereinyourclass?--________.A.TwentynineB.ThirtyandtwoC.Forty-fiveD.fifties()7.Whichnumberiswrong?_______.A.NinetyB.NinteenC.NinthD.Nineteenth()8.ThePeople'sLiberationArmywasfounded_______.A.onAugust1,1927B.in1927,1AugustC.onAugust1st,1927D.inAugust1,1927()9.Thenumber4,123isread_______.A.fourthousandonehundredandtwenty-threeB.fourthousandandonehundredtwenty-threeC.fourthousandandahundredandtwenty-threeD.fourthousandsahundredandtwenty-three()10.Theoldprofessorstillworkshardthoughheis_________.A.inhissixtyB.inhissixtiesC.insixtiesD.inthesixty()11.Thisclassroomis________ours.A.threetimesbigasB.asthreetimesbigasC.threetimesasbigasD.asbigthreetimesas()12.Thebasketballteamofourschoolranks________inthematch.A.threeB.thirdC.thethreeD.thethird()13.Whichisthecarthathedrives?It's________.A.fiftytwoB.thefifty-twocarsC.thecarfiftyfourD.thefifty-fourthcar()14.Whichofthefollowingiswrong?________.A.Heisafifteen-year-oldboy.B.Heisattheageof15.C.Heisaboyof15.D.Heisfifteenyearold.()15.Ourschoolisnotverybig.Thereareonly________students.A.ninehundredsofB.ninehundredC.ninehundredsD.ninehundredof()16.--Howmanynewwordsaretherein________lesson?--Thereareonly_________.3精品学习资料可选择pdf第3页，共6页-----------------------\nA.five;fifthB.fifth;fiveC.thefifth;thefiveD.thefifth;five()17.________,Coca-ColabegantoenterChina'smarket.A.In1970'sB.In1970sC.Inthe1970s'D.Inthe1970s()18.Therewasnobusinthatsmalltown.Wehada________.A.tenmileswalkB.ten-milewalkC.tenmile'swalkD.tenthmilewalk()19.Todayisthefirstdayand________.A.TuesdayisfourthB.ThursdayisthefourthC.secondisTuesdayD.asecondisThursday()20.Whichroomdoyoulivein?________.A.The201RoomB.Room201C.Room201stD.The201'sRoom()21.Howmanymagazinesdoyouhave?Ihave________.A.twoB.bothC.twiceD.thesecond()22.Threehundredthousandonehundredandseventymeans________.A.3,170B.3,117C.300,170D.30,170()23.OnMay________,________peopletraveledroundthecountry.A.thefirst,millionsB.thefirst,millionsofC.first,themillionthD.first,millions()24.________ofthemarediningatschool.A.TwelveB.TwelfthC.ThetwelveD.the12th()25.It's7:17isread________.A.sevenandseventeenB.sevensevenC.sevenonesevenD.sevenseventeen()26.Four________twoistwo.A.plusB.minusC.timesD.dividedby()27.Three________fiveiseight.A.plusB.minusC.timesD.dividedby()28.Three________sevenistwenty-one.A.plusB.minusC.timesD.dividedby()29.Forty-two________sevenissix.A.plusB.minusC.timesD.dividedby()30.Thereare________daysinayear.A.threehundredsixtyandfiveB.threehundredandsixty-fiveC.threehundredsandsixty-fiveD.threehundredsixty-five()31.Thereare________studentsinthatschool.A.twothousandeight-sixB.twothousandeighty-sixC.twothousandandeighty-sixD.twothousandsandeighty-six()32.Ittookme________togetthere.A.twohoursandahalfB.twohoursandhalfC.twohourandahalfD.twohourandhalf()33.Septemberis_________monthofthey
