基数词 序数词
1. 不规则类:
one→first, two→second, three→third
2. 普通类：第四至第十九一般在基数词后加-th，但也有四个特殊的，需加强记忆。
◆fifth (第五) 和twelfth (第十二)是把基数词five和twelve后的词尾ve变成f再加-th构成。
◆eighth (第八)是在基数词eight的后面
直接加-h构成。
◆ninth (第九)是将基数词nine的词尾e
去掉，再加-th构成。
基数词变序数词的方法
3. “ty”类：以“-ty”结尾的整十的基数词
变序数词时，把基数词的词尾y变为ie，再加-th，如：
twenty -- twentieth eighty -- eightieth
4. 几十几类：表示“几十几”的基数词
变序数词时，只需将个位变为序数词即
可，如：
thirty-eight--thirty-eighth
twenty-one -- twenty-first
seventy-nine -- seventy-ninth
基数词变序数词顺口溜
基变序，有规律，词尾加上th。
一二三 特殊记(first，second，third),
八加h(eighth), 九减e(ninth)
ve要用f替，(five fifth；twelve twelfth)
变y为ie，(twenty twentieth，
thirty thirtieth)-th 最后加上去，
若是第几十几，前为基，后为序。
(twenty-one twenty-first;
twenty-four twenty-fourth)
