1、巧记英语序数词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。基数词和序数词的练习题一、写出下列词的序
