【同步精讲】
“基数词”如何变“序数词”
序数词是由基数词变化而来的,其基本规则为:
1. 第1-19的序数词
除one→first,two→secon ( http: / / www.21cnjy.com )d, three→third有特殊形式外,其余序数词均由对应的基数词加th构成,其中有几个序数词拼法不规则,分别是five→fifth, eight→eighth, nine→ninth, twelve→twelfth。21·cn·jy·com
【指点迷津】一、二、三要全变①, 八去t,九去e, ve要用f替②;
① one→first, two→seco ( http: / / www.21cnjy.com )nd, three→third,一、二和三变为序数词时要全变化,要单独记;② 八和九,五和十变为序数词要注意某些字母的变化,eight→eighth, nine→ninth, five→fifth, twelve→twelfth
2. 二十后的序数词
整十的序数词将相应的基数的词尾ty中的y变为ie,再加th, 如:thirty→thirtieth
当表达第几十几时,十位数用基数词,个位变成序数词。如:twenty-two→twenty-second
【指点迷津】整十先把词尾y改为ie,再加th③。21教育网
要想表示几十几,只变个位就可以④。③整十的 ( http: / / www.21cnjy.com )数要先把词尾y改为ie再加-th,如:twenty→twentieth, thirty→thirtieth;④当表示两位数时则十位数用基数词,个位数用序数词,如:twenty-first【来源:21·世纪·教育·网】
为了书写方便,序数词常使用 ( http: / / www.21cnjy.com )缩写形式,即“阿拉伯数字+序数词的最后两个字母”,如: eleventh→11th, twentieth→20th, thirty-first→31stwww-2-1-cnjy-com
【同步精练】
一、写出下列词的序数词形式。(可以使用简写形式)
1.two_____ 2. four______ 3.five_____ 21*cnjy*com
4.nine______ 5. twenty ______ 6.thirty-three_______
二、选择合适的数词填空。

3. Mother’s Day is on the _____( two / second) Sunday in May.www.21-cn-jy.com
