1-100的序数词分为四个类。 1、第一类 first (1st) 第一 second (2nd) 第二 third (3rd) 第三 (在括号里的是缩写形式,均在阿拉伯数字后面加上相应序数词的最后两个字母构成,以下各类与此相同。)这类序数词只有三个,在整个序数词里面是特殊的,就和第一类基数词一样,需要逐个地硬记下来。 2、第二类: fourth (4th) 第四 fifth (5th) 第五 sixth (6th) 第六 seventh (7th) 第七 eighth (8th) 第八 ninth (9th) 第九 tenth (10th) 第十 eleventh (11th) 第十一 twelfth (12th) 第十二 thirteenth (13th) 第十三 fourteenth (14th) 第十四 fifteenth (15th) 第十五 sixteenth (16th) 第十六 seventeenth (17th) 第十七 eighteenth (18th) 第十八 nineteenth (19th) 第十九 这一类序数词共有十六个。均在相应的基数词后面加上后缀-th构成。要注意其中fifth、eighth、ninth、twelth四个词的拼法。 3、第三类: twentieth (20th) 第二十 thirtieth (30th) 第三十 fortieth (40th) 第四十 fiftieth (50th) 第五十 sixtieth (60th) 第六十 seventieth (70th) 第七十 eightieth (80th) 第八十 ninetieth (90th) 第九十 这一类全是十位整数的序数词,共八个。它们的构成方法是:先将相应的十位整数的基数词词尾-ty中的y改成i,然后在加上后缀-eth。 4、第四类: thirty-first (31th) 第三十一 sixty-second (62nd) 第六十二 eighty-seventh (87th) 第八十七 ninety-eighth (98th) 第九十八 这类表示“第几十几”的序数词,跟表示“几十几”的基数词一样简单。在构成方法上均由基数词“几十几”变化而来,十位数不变,仅把个位上的基数词变成序数词就行了。第一百 hundredth

扩展资料:
基数词1-10变序数词的规则,直接在后面加th 。 但是第一first,第二second,第三third不一样。还要注意第五是把five后面的ve变成f再加th,第八因为尾部已经有一个t, 所以直接加上h 。第九把nine后面的e去掉再加th。
基数词11-19变序数词,在此基础上加上th, 但是要注意的是第十二,是把十二twelve的ve变成f,再加th。
基数词二十几、十位上和个位数的数都是基数词。三十几,四十几...九十几亦是如此;基数词几十都是-ty结尾的,变序数词时把y 变ie ,再加-th.
序数词都是以th结尾的,除了first, second, third。
