first,second,third,fourth,fifth,sixth,seventh,eighth,ninth,tenth,eleventh,twelfth,thirteenth,fourteenth,fifteenth,sixteenth,seventeenth,eighteen,nineteenth
20-90，把y變成ie就行
twentieth^thirtieth^fortieth^fiftieth^sixtieth^seventieth^eightieth^ninetieth
21-99之間的非整十數，前面幾十是基數，後面是1-9的序數，如
23：twenty-third
這樣應該就沒問題了~
