基数词（记数法）
从数字的右端向左端数起，每三位数加一个逗号“，”。从右开始，第一个“，”前的数字后添加 thousand（千），第二个“，”前面的数字后添加 million（百万），第三个“，”前的数字后添加 billion（十亿）。
注意：1.只在几十几与百位间加上and
2.基数词在表示确切的数字时，不能使用百、千、 百万、十亿的复数形式
3. 当基数词表示不确切数字，如成百、成千上万时，基数词则以复数形式出现 如：thousands of 成千上万的 hundreds of 成百上千的

hundredth（第一百）
（2） 表示整十的基数词， 变 y为ie， 再加 th;
如：twentieth 第二十 eightieth第八十

基数词变序数词规则：

基变序有规律，结尾字母是 th; 一、二、三，特殊记，结尾字母是 t, d, d；八去t, 九去e; f 要把ve替。ty 将 y 变成 i, th前面有个e；几十几，也好记，只变个位就可以。
