基数词：指描述事物数量多少的词。
序数词：指表示顺序的数词。
1. (1-10)基数词）：one. two. three. four. five. six. seven. eight. nine. ten.
2. (1-10)序数词） ：first. second. third. fourth. fifth. sixth. seventh. eighth. ninth. tenth.
总结规则：基数词1-10变序数词的规则，直接在后面加th 。 但是第一first，第二second，第三third不一样。还要注意第五是把five后面的ve变成f再加th,第八因为尾部已经有一个t, 所以直接加上h 。第九把nine后面的e 去掉再加th。
3. （11-19)基数词）: eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen.
4. （11-19)序数词）: eleventh, twelfth, thirteenth, fourteenth, fifteenth, sixteenth, seventeenth, eighteenth, nineteenth.
