英语学习中英语基数词变序数词口诀(1-100的基数词变为序数词)

英语基数词变序数词口诀及用法（1-100的基数词变为序数词）表示数目和顺序的词叫做数词，数词又分为基数词和序数词。

基数词就是表示数量的数词。

序数词是表示顺序的数词。

基数词变序数词，其实有规律可循的，只要掌握了规律，就方便记忆和使用了，下面一起看看！基变序，有规律，词尾加上-th。

一，二，三，特殊记，词尾字母t，d，d。

八去t，九除e，ve要用f替，ty将y变成i，th前面有个e。

若是碰到几十几，前用基来后用序。

整十基数变序数，先把ty变成tie，要是遇上两位数，十位基数，个位序，th最后加上去。

一,二,三变字体；th从4上起；8加h,9减e；用f代ve；ty变为tie。

解析口诀：one→first，two→second，three→third这三个词变化特殊，要单独记；eight→eighth，nine→ninth，八去t，九去e后再加-th；five→fifth，twelve→twelfth，五、十二把ve换成f再加-th；twenty→twentieth，thirty→thirtieth... 整十先把词尾y改为ie再加-th。

两位数时则十位数用基数词，个位数用序数词，如：twenty-first。

解析说明：1、one、two、three这三个变为序数词分别是first、second、third这三个需单独记忆。

2、从第四开始，基数词变为序数词都要加th。

3、eight变为序数词的时候少个t不加只加h；nine变为序数词要去掉e再加th。

4、ve结尾的单词five和twelve变为序数词时要把ve改为f，再加th。

5、y结尾的单词即整十数的单词要把y变为ie，再加th。

6、如果把几十几的数变为序数词，只把个位上的数变为序数词就可以。
