记忆口诀
基变序,有规律,词尾加上“th”。
一,二,三(first、second、third)特殊记;
从4开始上th;5变ve改f(fifth),8去t(eighth),9减e(ninth);
几十尾巴ty变tie,后面跟上th(twentieth);
几十几,头不变,尾巴变,中间记得加个杠(twenty-fourth);
遇到特殊要除外(twenty-first)。

基数词和序数词的变化规则口诀
变化口诀1:
一、二、三,单独记;八去t,九除e,ve要用f替,整十基数变序数,先把ty变成tie;要是遇到两位数,十位基数个位序,th最后加上去。
变化口诀2:
基变序,容易记,加上th就可以;
一二三,特殊记,词尾字母tdd;
八减t,九减e,f来把ve替;
若是遇到整十数,ty变作tie;
若是遇到几十几,只变个位就可以。
解析:
1、one,two,three这三个变为序数词分别是first,second,third,这三个需单独记忆。
2、从第四开始,基数词变为序数词都要加th。
3、eight变为序数词的.'时候少个t不加只加h;nine变为序数词要去掉e再加th。
4、ve结尾的单词five和twelve变为序数词时要把ve改为f,再加th。
5、y结尾的单词即整十数的单词要把y变为ie,再加th。
6、如果把几十几的数变为序数词,只把个位上的数变为序数词就可以。
