one→first two→second three→third
five→fifth twelve→twelfth eight→eighth
nine→ninth
特殊情况：
1
特殊情况除外，4~19的序数词一般直接在词尾加th: four→fourth nineteen→nineteenth
2
以ty结尾的整十数的基数词要先变词尾的y为ie，再加th:
twenty→twentieth ninety→ninetieth
3
20以上非整十的两位数只将个位数变为序数词：
twenty-one→twenty-first
ninety-seven→ninety-seventh
4
序数词缩写=阿拉伯数字+序数词最后两个字母
基变序，有规律，词尾加上th，
一、二、三，单独记，词尾字母t、d、d，
八去t，九去e，f要把ve替，
整十变法也容易，ie要把y来替，
若是碰到几十几，只变个位就可以。
Listen, repeat and role-play.
