（四）数词01命题趋势考标导向化数词是历年中考试题中的必考知识点之一，所占分值不多，一般在1～2分之间，题型有选择题、词形变换题等。从命题内容来看，对基数词和序数词的基本用法、hundred,thousand,million,billion后面加不加-s或of、特殊形式的序数词、分数表示法的考查是中考命题的热点。预计2022年考查的重点极有可能是基数词和序数词的用法、分数表示法及hundred，thousand，million的用法。02定义概念清晰化数词就是用于表示数目的多少或顺序的先后的词，分为基数词和序数词两种。表示数量的数词是基数词，如one,two,three等；表示顺序的数词是序数词，如first,second,third等。03知识归类知识网络化❶基数词的构成分类图解one1two2three3four4five5six6seven7eight8nine9ten10eleven11twelve12thirteen13fourteen14fifteen15sixteen16seventeen17eighteen18nineteen19twenty20twenty-one21twenty-two22thirty30forty40fifty50sixty60seventy70eighty80ninety90onehundred100onehundredandone101twohundred200特例清单1.1000以上的基数词的表示方法是：从右向左用分节号“，”分节，每三个数字为一个节，第一个分节号前用thousand，第二个分节号前用million，第三个分节号前用billion(美)或thousandmillion(英)。如：2，418，000，000twobillion,fourhundredandeighteenmillion或twothousand,fourhundredandeighteenmillion2.hundred,thousand,million,billion等用在具体的数字后面时不能加-s或of；hundred,thousand,million,billion等前面没有具体的数字时通常加-s或of。如：eightthousandpeople八千人fiftythousandtrees五万棵树thousandsof成千上万的millionsof数百万3.“基数词+单数名词”相当于复合形容词，作名词的定语，用于表示时间、距离等。如：the100-metrerace100米赛跑aten-minutewalk10分钟的路程4.常见的数字符号和等式的读法：=(等于号)读作equals，+(加号)读作plus或and，-(减号)读作minus，×(乘号)读作times或multipliedby，÷(除号)读作dividedby。如：3+2=5读作Threeplustwoequals(或is)five./Threeandtwois(或equals)five./Threeandtwomakesfive.5-3=2读作Fiveminusthreeequals(或is)two.8×7=56读作Eighttimessevenequals(或is)fifty-six./Eightmultipliedbysevenisfifty-six.10÷5=2读作Tendividedbyfiveequals(或is)two.5.“基数词+more”或“another+基数词”表示“在原来的基础上增加的数量”。如：MygrandmotherwillstayinShanghaifortwomoreweeks.=MygrandmotherwillstayinShanghaiforanothertwoweeks.我的奶奶将在上海再待两周。【题组训练】()1.(2022·东营)Whenhearrivedattheairport，LeeMinhofoundthat____fanswerewaitingforhimthere.A.hundredB.hundredsC.hundredofD.hundredsof5\n()2.(2022·山西)—Jack，Iwanttogoto____toseeadentist.Couldyoutellmetheaddress?—Noproblem.A.Room606B.No.2HospitalC.FifthAvenue()3.(2022·淮安)Sheenjoyscollecting.Shehascollectedoverthree________stamps.A.hundredB.hundredsC.hundredofD.hundredsof()4.(2022·兰州)PleaseturntoPage____andreadthe____story.A.Ten;twoB.Ten;secondC.Tenth;secondD.Tenth;two()5.(2022·南宁)Theyarethestudentsof_______.A.grade7B.Grade7C.7thgradeD.Grade7th❷序数词的构成分类图解first1st第1second2nd第2third3rd第3fourth4th第4fifth5th第5sixth6th第6seventh7th第7eighth8th第8ninth9th第9tenth10th第10eleventh11th第11twelfth12th第12twentieth20th第20twenty-first21st第21thirtieth30th第30thirty-ninth39th第39fortieth40th第40fiftieth50th第50sixtieth60th第60seventieth70th第70eightieth80th第80ninetieth90th第90hundredth100th第100onehundredandfirst101st第101特例清单1.序数词在使用时，通常前面要加定冠词the；但是如果序数词前出现不定冠词a或an时，则表示“再一”，“又一”。如：We’llgooveritasecondtime.我们得再念第二遍。We’vetrieditthreetimes.Mustwetryitafourthtime?我们已经试过三遍了，还必须试一次(第四次)吗？2.基数词也可以表示顺序。只需将基数词放在它所修饰的名词之后即可，不需要添加定冠词。如：thefirstlesson——LessonOnethefifthpage——Page5(Five)thetwenty-firstroom——Room21(Twenty-one)【题组训练】()6.(2022·孝感)—IhearyourpenpalisvisitingWuhanagain.Isitthe____timeforhim?—Yes，andhewillcomeforathirdtimenextspring.A.firstB.secondC.thirdD.fourth()7.(2022·孝感)Todayistheboy’s_____birthday.Heis12yearsold.A.twelveB.twelvthC.twelfthD.thetwelfth()8.(2022·天津)_____monthoftheyearisMay.A.TwoB.ThesecondC.FiveD.Thefifth()9.(2022·凉山)—HaveyouevercometoXichangbefore?—Yes.Thisismy______visittoXichang，Ihavecomeheretwicebefore.A.twoB.secondC.threeD.third()10.(2022·成都)—Whichmonthoftheyeardoyoulike?—July，the______monthbecausesummervacationbeginsinthismonth.A.secondB.seventhC.ninth❸数词的常见用法分类图解用法例子句法功能主语Itissaidthatthirteenisanunluckynumber.ThefirstdayofMayisInternationalLabourDay.宾语Itisworththreehundred.Hewasamongthefirsttoarrive.定语Thereareonlythreeboysintheclass.Mayisthefifthmonthofayear.表示事物编号No.TenMiddleSchool,LessonOne5\n表示年代inthe1890s表示年、月、日OnMay1st,2022表示分数分子是基数词，分母是序数词，当分子大于1时，分母用复数形式。如：onethird,fivesixths表示时间整点Tomoftengetsupatsixinthemorning.
