英语基数词变序数词规律（优秀范文五篇）

第一篇：英语基数词变序数词规律英语基数词变序数词规律英语中基数词变序数词一直是中考的重点，也是学生认为比较难掌握的知识点。在近几年的教学中，我不断摸索并借鉴其他教师总结了一首顺口溜帮助学生记忆基数词变序数词规律。实践证明，该方法是行之有效的，现整理出来和大家一起分享，如有不当之处，敬请批评指正。基数词变成序数词，加上th莫迟疑；八去t,九去e,y结尾变ie;five,twelve两兄弟，常用f替ve;若是遇到几十几，只变个位就可以；只有三个特殊记，一二三尾t,d,d.释义：基数词变成序数词，加上th莫迟疑基数词变序数词，一个大的原则就是在基数词词尾加上th,可以说绝大多数序数词都是以th结尾的。如：six-sixth,ten-tenth.八去t,九去e,y结尾变ie;八（eight）变序数词第八时，需要把词尾字母t去掉，然后再加th;九（nine）变序数词第九时，需要把词尾字母e去掉，然后再加th；英语中二十以上的整十都是以ty结尾的，对于这些基数词变序数词时需要把词尾的字母y变成ie,然后再加th.如：twenty-twentieth.five,twelve两兄弟，常用f替ve;five,twelve两个单词变序数词时，需要把词尾的字母ve换成f,然后再加th.若是遇到几十几，只变个位就可以；英语中表示几十几的基数词变序数词时，该单词的十位不用变，只需要把个位变成相应的序数词即可.如：twenty-four变成twenty-fourth.只有三个特殊记，一二三尾t,d,d.英语基数词变序数词中，只有三个需要特殊记忆，分别是第一(first),第二（second）,第三(third).第二篇：英语1-100基数词和序数词基数词one2two3three4four5five6six7seven8eight9nine10ten11eleven12twelve13thirteen14fourteen15fifteen16sixteen17seventeen18eighteen19nineteen20twenty21twenty-one22twenty-two23twenty-three24twenty-four25twenty-five26twenty-six27twenty-seven28twenty-eight29twenty-nine30thirty31thirty-one32thirty-two33thirty-threethirty-four35thirty-five36thirty-six37thirty-seven38thirty-eight39thirty-nine40forty41forty-one42forty-two43forty-three44forty-four45forty-five46forty-six47forty-seven48forty-eight49forty-nine50fifty51fifty-one52fifty-two53fifty-three54fifty-four55fifty-five56fifty-six57fifty-seven58fifty-eight59fifty-nine60sixty61sixty-one62sixty-two63sixty-three64sixty-four65sixty-five66sixty-six67sixty-sevensixty-eight69sixty-nine70seventy71seventy-one72seventy-two73seventy-three74seventy-four75seventy-five76seventy-six77seventy-seven78seventy-eight79seventy-nine80eighty81eighty-one82eighty-two83eighty-three84eighty-four85eighty-five86eighty-six87eighty-seven88eighty-eight89eighty-nine90ninety91ninety-one92ninety-two93ninety-three94ninety-four95ninety-five96ninety-six97ninety-seven98ninety-eight99ninety-nine100onehundred序数词第1first第2second第3third第4fourth第5fifth第6sixth第7seventh第8eighth第9ninth第10tenth第11eleventh第12twelfth第13thirteenth第14fourteenth第15fi
