1-100基数词和序数词怎么记?
一基数词记忆歌诀:
1至12单独记,13至19-teen结尾;
整十词尾是-ty,记清何时连字符;
百十之间用and。
*十五五十别多e,十九九十别少e 。
*二三四五八,个十首相差。
说明:① 十五、五十的正确写法分别是fifteen, fifty。最容易错写成fifeteen, fifety。 十九、九十的正确写法分别是nineteenth, ninety。最容易错写成nineeenth, ninty。要特别注意!
②“二三四五八,个十首相差”指的是“二三四五八”这几个数字做个位数和做十位数时,其英语单词开头写法是不同的。如:two—twelve—twenty,three—thirteen—thirty, four—fourteen—forty,five—fifteen—fifty。
二序数词记忆歌诀:
第1、2、3、12单独记;
第五第九均无e;
整十y变ie,然后再加-th ;
整十带个是“基 序”; 其余直接加-th。
说明:序数词有两种写法:
①用英语单词;
②用“阿拉伯数字 词尾-st/-nd/-r/-th”
first—1st eleventh—11th twenty-first—21st
second—2nd twelfth—12th twenty-second—22nd third—3rd
thirteenth—13th twenty-third—23rd
fourth4—4th fourteenth—14th twenty—fourth 24th
