大数字的表达方法
数词
数词的概念：表示数目多少或者顺序先后的词叫数词。
它有两种形式：
1. 表示数目多少的叫基数词。如：one一，two二，three三，four四。
2. 表示顺序先后的词叫序数词。如：first第一，second第二，third第三，fourth第四，fifth第五。
数词：基数词
基数词的构成：
(1) 1－12的基数词是：one 1，two 2，three 3, four 4， five 5, six 6, seven 7, eight 8, nine 9, ten 10, eleven 11,twelve 12。
(2) 13－19的基数词：分别在3－9的基数词后加词缀－teen，但要注意几个特殊变化的基数词：13－thirteen，15－fifteen，18－eighteen。
(3) 20－90的逢十的基数词：分别在2－9的基数词后加－ty构成，即：20－twenty，30－thirty， 40－forty，50－fifty，60－sixty，70－seventy，80－eighty，90－ninety。（注意20，30，40，50，80拼写的特殊变化。）
数词：基数词
(4) 21－29的基数词：由十位数20的单词形式twenty加个位数1－9构成。中间用连字符。即：21－twenty-one
(5) 百位数是由1－9加hundred构成。例如：200－two hundred。有百位数、十位数和个位数的三位数，百位数和十位数之间用and连接。例如：127－one hundred and twenty-seven。
(6) 千位数是由1－9加thousand构成，后面的百位数、十位数和个位数与前面的构成方法一样。例如：3000－three thousand。
数词：序数词
序数词的构成：
(1) 1－19的序数词除了第一（first），第二（second）和第三（third）之外，其他的序数词是由基数词加后缀－th构成的。
如：第四－fourth，第六－sixth，第七－seventh等。
注意：
几个序数词的特殊变化：fifth 第五，eighth 第八，ninth 第九，twelfth 第十二。
数词：序数词
序数词的构成：
(2) 整十的序数词的构成方法是：先将“几十”的基数词的词尾-y变为-ie再加th。
如：第20－twentieth，第30－thirtieth，第40－fortieth。
(3) 两位数的序数词如果包含1－9的个位数，十位数用基数词，个位数用序数词。
如：第21（twenty-first），第34（thirty-fourth）等。
(4) 百、千、万的序数词有hundred－hundredth，thousand－thousandth等。
数词：分数
分数的构成：子基母序，当分子大于1时，分母+S
a half 1/2 one third 1/3 two thirds 2/3
a (one) quarter 或one fourth 1/4
