1、一、基数词下面把100以内的基数词分为四类。1、第一类：one一two二three三four四five五six六seven七eight八nine九ten十eleven十一twelve十二这一类共计十二个单词，在结构上与其他的基数词相比较是特殊的，就象不规则的动词一样，要求逐个的硬背下来，这对学好其他的基数词和序数词都是及其重要的。 2、第二类：thirteen十三fourteen十四fifteen十五sixteen十六seventeen十七eighteen十八nineteen十九这一类基数词共有七个。它们在结构上有两个特点：一是在发音方面都有两个重音；二是在拼法上都有后缀teen。除了thir

2、teen和fifteen之外，都是纯粹地在另一个基数词的后面加上后缀teen。但要注意eighteen的拼法，eight本身有t字母，因此只加een。3、第三类：twenty二十thirty三十forty四十fifty五十sixty六十seventy七十eighty八十ninety九十这类基数词共有八个。都是十位的整数，均以后缀ty结尾。其中sixty、seventy、eighty、ninety基本上是在相应的基数词后面加上后缀ty。但要注意eighty的拼法，eight本身有t字母，因此只加y。 4、第四类：这一类和很简单，可以看成是一种合成词。其结构方式是：用十位整数加上个位整数，其间用连

3、字符号“”连接，表示“几十几”。这类基数词的变化都是规则的。如：twenty-one二十一forty-six四十六seventy-eight七十八ninety-five九十五二、序数词下面把199的序数词也分为四个类。1、第一类first(1st)第一second(2nd)第二third(3rd)第三（在括号里的是缩写形式，均在阿拉伯数字后面加上相应序数词的最后两个字母构成，以下各类与此相同。）这类序数词只有三个，在整个序数词里面是特殊的，就和第一类基数词一样，需要逐个地硬记下来。2、第二类：fourth(4th)第四fifth(5th)第五sixth(6th)第六seventh(7th)第七

4、eighth(8th)第八ninth(9th)第九tenth(10th)第十eleventh(11th)第十一twelfth(12th)第十二thirteenth(13th)第十三fourteenth(14th)第十四fifteenth(15th)第十五sixteenth(16th)第十六seventeenth(17th)第十七eighteenth(18th)第十八nineteenth(19th)第十九这一类序数词共有十六个。均在相应的基数词后面加上后缀th构成。要注意其中fifth、eighth、ninth、twelth四个词的拼法。 3、第三类：twentieth(20th)第二十thir

5、tieth(30th)第三十fortieth(40th)第四十fiftieth(50th)第五十sixtieth(60th)第六十seventieth(70th)第七十eightieth(80th)第八十ninetieth(90th)第九十这一类全是十位整数的序数词，共八个。它们的构成方法是：先将相应的十位整数的基数词词尾ty中的y改成i，然后在加上后缀eth。 4、第四类：thirty-first(31th)第三十一sixty-second(62nd)第六十二eighty-seventh(87th)第八十七ninety-eighth(98th)第九十八这类表示“第几十几”的序数词，跟表示“几

6、十几”的基数词一样简单。在构成方法上均由基数词“几十几”变化而来，十位数不变，仅把个位上的基数词变成序数词就行了。基数词及序数词重要用法1. 基数词的用法基数词用于表示事物的数量，在表示基数词时，要特别注意hundred, thousand, million, billion等几个词的用法：若其前用了基数词，则不论其面是否有of，都必须用单数形式(此时若带of则通常表示特定范围中的一部分)；若泛指数百、数千、数百万等，则用 hundreds of, thousands of, millions of 等这样的结构。如：Two hundred of the students are needed

7、 to plant trees this morning. 今天中午需要200个学生去植树。Hundreds of people attended the famous directors farewell concert. 好几百人出席了这位著名指挥家的告别音乐会。Thousands upon thousands of English words come from foreign tongues. 成千上万英语单词来自外来语。2. 基数词的复数用法逢整“十”的基数词的复数形式可用于表示某人的大约年岁和世纪中的年代。如：The war broke out in the nineties. 这

8、次战争爆发于90年代。Karl Mark began to learn the Russian language in his fiftieth. 马克思五十多岁开始学俄语。3. 序数词的用法序数词用于表示事物的顺序，一般由与之相应的基数词加th构成(但有特殊形式需特别记忆)；序数词主要用作定语，前面一般要加定冠词(或物主代词)。如：Their second son is a doctor. 他们的二儿子是个博士。The hundredth cave that George has discovered in his lifetime is near the Alps. 乔治一生中找到的第一百

9、个山洞在阿尔卑斯山附近。注：序数词前有时可用不定冠词，表示“每一，又一”。如：Well have to do it a second time. 我们将再做一遍。词尾加上-ed(fourth,sixth) 一、二、三，特殊例， 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) ty将y改成i, th前面有个e。 若是碰到几十几，前用基来后用序。 或记忆为：一、二、三，特殊记，词尾字母t,d,d 八加h,九减e,逢十改y为ie f要把ve替，还有th莫忘记 【语言实践内容梳理】1. 数词分基数词

10、和序数词。基数词表示数目，序数词表示顺序。基数词(1)112为独立的单词，有其各自的形式。如one，two，three，twelve等。(2)1319都以teen结尾，单词中的两个音节都读重音。如thirteen，fourteennineteen等。(3)2090十位数的整数都以-ty结尾，单词中的第一个音节重读。如twenty，thirtyninety等。(4)hundred是“百”，thousand是“千”，ten thousand是“万”，one hundred thousand 是“十万”，million是“百万”，ten million 是“千万”。(5)在表示一个具体的数目时，hu

11、ndred，thousand，million 后面都不能加“s”。如:two thousand，seven million等。在表示一个不确定的数目时，hundred， thousand，million 后面要加“s”。如：“成千上万”thousands of，“数百万”millions of 等。(6)20以上的基数词的读法：a. 两位数的读法，在十位和个位之间加连字符(即“-”)如：22 twenty-two， 35 thirty-fiveb. 三位数的读法，在百位之后加“and”。如：136 one hundred and thirty-six， 498 four hundred and

12、 ninety-eightc. 四位及四位以上数的读法，只在百位之后加and，而千位、万位以上的数后面不加任何词，只按顺序读。如：1 234 one thousand two hundred and thirty-four，5 864 327 five million eight hundred and sixty-four thousand three hundred and twenty-seven2. 序数词(1)第一、第二、第三分别为first，second，third。(2)第四到第十九都由相应的基数词加th构成。如：fourth，seventh等。要注意fifth，eighth，n

13、inth和twelfth的拼写法和读法。(3)十位数的序数词由相应的基数词去掉词尾y加ieth构成。如：twentieth，fiftieth等。(4)第二十一到九十九等，前面的十位数用基数词，后面的个位数用序数词，中间用连字符“-”连接。如：twenty-first，twenty-ninth，seventy-eighth 等。(5)第一百、第一千、第一百万分别在相应的基数词后面加th。即:hundredth，thousandth，millionth。(6)序数词之前一般要加定冠词或代词。如：The second truck is carrying fewer baskets than the

14、first one. This is her first visit to China. 有时，序数词前用不定冠词，表示“再一、又一”的意思。如：He failed once. Then he tried a second time. 他曾经失败一次，然后他又试了一次。3. 年月日表达法(1)年份，每两位数读一个词。如：1949 nineteen forty-nine 1900 nineteen hundred(2)先月后日，日子要读成序数词。如：5月1日 May (the) first可写成 May 1 3月8日 March (the) eighth可写成March 8(3)先日后月，在月份

15、之前加of。如：5月1日 the first of May 3月8日 the eighth of March(4)年月日同时出现，把年代放在最后，年代前用逗号隔开。如1949年10月1日，可写成：the first of October，1949或October (the)first，1949。4. 时刻表达法(1)用基数词，按顺序读。如：7：30 seven thirty， 8：15 eight fifteen， 12：00 twelve (oclock)(2)用介词past，past之前为分钟数(须在半小时以内，包括半小时)，past之后为钟点数。如：6：11 eleven past si

16、x ，7：15 fifteen (a quarter) past seven9：30 thirty (half) past nine(3)用介词to，to前为分钟数(须在半小时以上，不包括半小时)，to之后为下一个钟点数，表示“差几分到几点”。如：6：58 two to seven，7：45 fifteen (a quarter) to eight 5. 编号表达法(1)用No. No. (读Number)后加数字，数字读基数词。如：No. 1 Number One， No. 3 bus Number Three bus(2)用序数词 词序为：the + 序数词+名词 如:the first

17、lesson，the Second World War(3)用基数词 词序为：名词(词首字母大写)基数词(如用英语拼写，词首字母也要大写)如：Lesson One，Class Four，World War Two。此种方法较常见，特别是当数字较长时。如：Room 306，No. 106 Middle School。6. 分数表达法分子用基数词，分母用序数词，若分子大于1时，分母要在序数词后加s。如：1/3，one third，2/5，two fifths等。7. 数学运算的表达法“加”用plus或and，“减”用minus，“乘”用times，“除”用divided by，动词多用单数。如：3

18、+5=8Three plus/and five is eight. 9-2=7Nine minus two is seven. 65=30Five times six is thirty. 82=4 Eight divided by two is four. 基数词序数词练习题I. Choose the best answer1. Please turn to _. A.
