基变序，有规律，
词尾加上th
123，特殊记，first,second,third,
8加h，9去e，f来把ve替，
遇到整十莫着急，只需把y变ie，（十除外）
后加th莫忘记，（eighth、ninth、fifth、twelfth、twentieth）
若是遇到几十几，只变个位就可以（十几除外）
基数词（1~20）：one two three four five six seven eight nine ten eleven twelve thirteen fourteen fifteen sixteen seventeen eighteen nineteen twenty
序数词（1~20）：first second third fourth fifth sixth seventh eighth ninth tenth eleventh twelfth thirteenth fourteent fifteenth sixteenth seventeenth eighteenth nineteenth twentieth.
至于基数词，只要记住0到12都是不一样的，凡是涉及到13，3在十位上时three统统改成thir-，40的时候变化特别，Forty，去掉u，剩下整十的+ty（十，二十除外）。
也就是说变化上容易出错的只有9th（第九），40（基数词）。
望采纳
基数词：1到12要单个记：one/two/three/four/five/six/seven/eight/nine/ten/eleven/twelve;
13到19有规律：thirteen/fourteen/fifteen/sixteen/seventeen/eighteen/nineteen;teen结尾
整十有规律：twenty ty结尾。
序数词：基变序有规律，词尾加上th;fourth/sixth/seventh/tenth/elenventh /thirteenth
1，2，3，有规律，结尾字母t/d/d: first/second/third;
八去t，九去e，ve 要用f 替;eighth/ninth five-fifth/twelve-twelfth
ty将y 变i， th 前面有个 e。twenty-twentieth
one-first
two-second
three-third
four-forth
five-fifth
six-sixth
seven-seventh
