作主语、宾语、定语或表语。基数词要变为序数词是有规律可循的，其方法及具体示例如下：一

、序数词2.构成：1.

定义：规律示例1~19,一般在基数词后加-thsix—sixthseventeen—seventeenth20~90之间的整十的序数词是把对应的基数词末尾的y变为ie,再加-thtwenty—twentieththirty—thirtieth20以后的非整十的两位或两位以上

的基数词变为序数词时，只将个位

数变为序数词twenty-two—twenty-secondone—first

two—second特殊变化的基数词1、2、3、5、8、9、12等需单独记忆three—third

five—fifth

eight—eighth

nine—ninth

twelve—twelfth1,2,3,特殊记；从第4,加

th;5和12,也好记，若要表示整十数，th接上莫迟疑，只变个位就可以。基变序，有规律。结尾时，t,d,d;8加h,

9去e;f来把

ve

替；词尾y,

变

ie;如要表示几十几，巧记歌诀序数词都有缩写形式：在阿拉伯数字后加该序数词的最后两个字母。示例如下：first

1stthird→

time!(1)序数词前一般要加定冠词the,尤其是单独使(2)序数词作名词的定语，一般前面要加the

用the

this

your

分子用基数词，分母用序数词。当分子大于1时，分母的序数词要用复数形式。one
