Can
you
find
out
the
rules
一般在基数词后直接加th。
e.g.
four-fourth,
eleven-eleventh
2.以ve结尾的变ve为f，再加th。
3.
以ty结尾的整十数，变y为ie，再加th。
4.第20以上的“第几十几”，十位不变，个位变为相应的序数词。
5.特殊的：
e.g.
five-fifth,
twelve-twelfth
e.g.
twenty-twentieth
thirty-thirtieth
e.g.
twenty-one
twenty-first
thirty-three
thirty-third
第一（first）、第二（second）、第三（third）
第八（eighth）、第九（ninth）。
基变序
有规律
one→first
two→second
three→third
一、二、三
特殊记
four→fourth
th要从四加起
eight→eighth
nine→ninth
八去t,九去e
five→fifth
twelve→twelfth
ve要用f替
twenty→twentieth
thirty→thirtieth
几十改y为ie
twenty-one→twenty-first
thirty-four→thirty-fourth
若遇几十几，只变个位就可以
