序数词基数词变序数词顺口溜基变序，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,（fivefifth；twelvetwelfth）变y为ie,（twentytwentieth，thirtythirtieth）-th

最后加上去，若是第几十几,前为基,后为序。(twenty-onetwenty-first;twenty-fourtwenty-fourth)基数词变序数词表示顺序的数词叫序数词。基数词变序数词的规则是：（1）一般在基数词后加th

：

fourth（第四）thirteenth（第十三）hundredth（第一百）（2）以整十的基数词，变y为ie，再加th，如：

twentieth第二十eightieth第八十（3）特殊的序数词有：第一first，第二second，第三third，第五fifth，第八eighth，第九ninth，第十二twelfth

（4）要把一个“几十几”，“几百几”的基数词变成序数词，只需把个位数变成序数词。

32---thirty-second256---twohundredandfifty-sixth(5)在表达编号的东西时，可以用基数词表示，也可用序数词表thefirstlesson=LessonFirstthesixthgrade=GradeSix一.第1,第2,第3：
