基数词和序数词的练习题

巧记英语序数词以及基数词和序数词的练习题英语中的数词分为基数词和序数词，而基数词和序数词的的变化学生常出现错误，在教学过程中我总结了以下口诀，学生们用起来就简单多了，并且还不会出错。

基变续，有规律，词尾加上th;
一二三，特殊记，词尾字母t,d,d(first,second,third);
八减t(eighth), 九去e(ninth)，f来把ve替(five---fifth,twelve---twelfth);
单词ty作结尾，ty变成tie(twenty-twentieth);
若是碰到几十几，只变个位就可以(twenty-one----twenty-first).
序数词表顺序，一般需用定冠词。
