14、、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thirteen和fifteen之外，都是纯粹地在另一

15、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，其间用连字符号“”连接，表示“几十几”。这类基数词的

16、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eighth(8th)第八ninth(9t

17、h)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thirtieth(30th)第三十fortiet

18、h(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。专心-专注-专业
