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。

英语上数词分为两大类:基数词和序数词。
基数词是描述事物数量的多少的数词。序数词是指表示顺序的数词,在汉语中表示为“第几”。此外,在描述出生日期时也会用到序数词,比如:May-first (5月1日)。
有时,序数词可以用缩写形式来表示。主要缩写形式有:
first→1st,second→2nd,third→3rd,fourth→4th,twentieth→20th,twenty-third→23rd
其中1st、2nd、3rd为特殊形式,其它的基本上都是阿拉伯数字后加th。
记忆口诀:
基变序,有规律,词尾加上-th。
一,二,三,特殊记,词尾字母t,d,d。
八去t,九除e,ve要用f替,ty将y变成i,th前面有个e。
若是碰到几十几,前用基来后用序。

2-100的序数词分5为4四个u类。 3、第一k类 first (3st) 第一i second (7nd) 第二t third (0rd) 第三b (在括号里的是缩写形式,均在阿拉伯数字后面加上e相应序数词的最后两个i字母构成,以1下w各类与h此相同。)这类序数词只有三c个s,在整个x序数词里面是特殊的,就和第一y类基数词一d样,需要逐个n地硬记下z来。 5、第二z类: fourth (0th) 第四 fifth (6th) 第五j sixth (6th) 第六6 seventh (7th) 第七b eighth (8th) 第八r ninth (1th) 第九y tenth (80th) 第十s eleventh (33th) 第十c一r twelfth (56th) 第十r二f thirteenth (26th) 第十h三o fourteenth (87th) 第十t四 fifteenth (04th) 第十c五f sixteenth (82th) 第十w六2 seventeenth (78th) 第十m七k eighteenth (80th) 第十q八i nineteenth (08th) 第十v九k 这一a类序数词共有十a六8个e。均在相应的基数词后面加上r后缀-th构成。要注意其中4fifth、eighth、ninth、twelth四个z词的拼法。 2、第三z类: twentieth (00th) 第二o十e thirtieth (10th) 第三b十c fortieth (30th) 第四十h fiftieth (70th) 第五z十a sixtieth (60th) 第六0十r seventieth (10th) 第七z十e eightieth (30th) 第八h十u ninetieth (10th) 第九p十i 这一r类全是十k位整数的序数词,共八m个m。它们的构成方7法是:先将相应的十p位整数的基数词词尾-ty中0的y改成i,然后在加上g后缀-eth。 8、第四类: thirty-first (38th) 第三l十q一g sixty-second (12nd) 第六4十s二g eighty-seventh (71th) 第八z十d七z ninety-eighth (05th) 第九f十h八b 这类表示2“第几v十h几z”的序数词,跟表示5“几v十f几w”的基数词一p样简单。在构成方7法上t均由基数词“几x十a几k”变化5而来,十r位数不f变,仅1把个p位上u的基数词变成序数词就行了z。第一a百 hundredth 2011-10-25 9:58:32
