说明
1、许多序数词是由相应的基数词后加th构成的,如:four / fourth,six / sixth,ten / tenth,sixteen / sixteenth,但是nine变为序数词是ninth,而不是nineth。
2、twentieth, thirtieth, fortieth等表示整十的序数词,由相应的基数词将词尾y改为ie,再加th构成。
3、first, second, third通常可缩写为1st, 2nd, 3rd。凡是以th结尾的序数词可缩写为“基数词+th”:4th, 5th, 9th, 11th, 60th, 128th等。
4、非整十的多位数,将个位数变成序数词即可:twenty-first(第21),thirty-sixth(第36),ninety-ninth(第99),three hundred and sixty-fifth(第365)等。
