第十一 eleventh (11t h) 第十二 twelfth (12th) 第十三 thirteenth (13th) 第十四 fourteenth (14th) 第十五 fifteenth (15th)
sixteenth (16th) 第十六 seventeenth (17th) 第十七 eighteenth (18th) 第十八 nineteenth (19th) 第十九
3、第三类: 这一类全是十位整数的序数词,共八个。 它们的构成方法是:先将相应的十位整数的基数词 词尾-ty中的y改成i,然后在加上后缀-eth。
第二十 twentieth (20th) 第三十 thirtieth (30th) 第四十 fortieth (40th) 第五十 fiftieth (50th)
第六十 sixtieth (60th) 第七十 seventieth (70th) 第八十 eightieth (80th) 第九十 ninetieth (90th)
4、第四类: 这类表示“第几十几”的序数词,跟表示“几十几” 的基数词一样简单。在构成方法上均由基数词“几 十几”变化而来,十位数不变,仅把个位上的基数 词变成序数词就行了。
2、第二类:“13-19”的基数词以teen结尾,除了thirteen和fifteen特别 点之外,它们后面都只加teen就可以了。 但要注意eighteen的拼法,eight本身 有t字母,因此只加een。
