为序数词时，有特别之处。

1.one--- first, two --- second, three --- third, five --- fifth, nice --- ninth, twelve --- twelfth2. 以ty 结尾的单词，要先变y为I, 在加-eth. 例如：thirty ---thirtieth, fifty ---fiftieth3. 以one, two, three 等结尾的多位数词，要将各位数变成序数词。

例如：twenty-one --- twenty-first, one hundred and one --- one hundred and first注意：序数词前常用定冠词，有时还可以用不定冠词a/an 则表示"又一"的意思。
