- 序数词
(1) 构成
基变序，有规律，词尾加上th。
一二三 特殊记(first，second，third),
八加h(eighth), 九减e(ninth)
ve要用f替(five-fifth；twelve-twelfth)
把y变为i和e，(twenty-twentieth，thirty-thirtieth) 最后加上-th，
若是第几十几，前为基，后为序。(twenty-one---twenty-first, twenty-four---twenty-fourth)
(2) 用法
①序数词前一般要加定冠词the表示顺序，但是当前面已经有形代等修饰时，则不能在加the；
②序数词常用缩写形式，“阿拉伯数字+个位序数词的后两个字母”: 1st,2nd,3rd,11th,12th,13th,21st,22nd,23rd,31st...
③序数词可表示日期“几月几日”中的“几日” October 1st
