小学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。
