英语中1-100的序数词
英语中1-100的序数词
精心整理各位家长：从本学期的第二单元起，孩子开始接触英语的序数词。
之前孩子接触的数词都是基数词，现阶段可能会有一些混淆与不熟练。
本学期必须掌握的序数词为【第1-第12】，其中【第1、2、3】尤其重要，必须会背会默。
不过在今后的各种练习题中，可能会出现12以外的序数词，为了方便孩子查阅使用，我整理了1-100的序数词，并列出对应基数词。
怕有误会，再说明一次：并不需要100个序数词全背出或默出，有要求的只有前12，其他的只要用时查看即可（但是对之后的构成规律必须有所了解）1-100序数词：第1first第2second第3third第4fourth第5fifth第6sixth第7seventh第8eighth第9ninth第10tenth第11eleventh第12twelfth第13thirteenth第14fourteenth第15fifteenth第16sixteenth第17seventeenth第18eighteenth第19nineteenth第20twentieth第21twenty-first第22twenty-second 第23twenty-third第24twenty-fourth 第25twenty-fifth第26twenty-sixth第27twenty-seventh 第28twenty-eighth 第29twenty-ninth第30thirtieth第31thirty-first第32thirty-second 第33thirty-third第34thirty-fourth第35thirty-fifth 1-100基数词：1one2two3three4four5five6six7seven8eight9nine10ten11eleven12twelve13thirteen14fourteen15fifteen16sixteen17seventeen 18eighteen19nineteen20twenty21twenty-one 22twenty-two 23twenty-three 24twenty-four 25twenty-five 26twenty-six27twenty-seven 28twenty-eight 29twenty-nine 30thirty31thirty-one32thirty-two33thirty-three 34thirty-four35thirty-five第36thirty-sixth第37thirty-seventh第38thirty-eighth第39thirty-ninth第40fortieth第41forty-first第42forty-second第43forty-third第44forty-fourth第45forty-fifth第46forty-sixth第47forty-seventh第48forty-eighth第49forty-ninth第50fiftieth第51fifty-first第52fifty-second第53fifty-third第54fifty-fourth第55fifty-fifth第56fifty-sixth第57fifty-seventh第58fifty-eighth第59fifty-ninth第60sixtieth第61sixty-first第62sixty-second第63sixty-third第64sixty-fourth第65sixty-fifth第66sixty-sixth第67sixty-seventh第68sixty-eighth第69sixty-ninth第70seventieth第71seventy-first第72seventy-second 第73seventy-third第74seventy-fourth 第75seventy-fifth第76seventy-sixth第77seventy-seventh 第78seventy-eighth 第79seventy-ninth第80eightieth第81eighty-first 36thirty-six37thirty-seven 38thirty-eight39thirty-nine40forty41forty-one42forty-two43forty-three44forty-four45forty-five46forty-six47forty-seven48forty-eight49forty-nine50fifty51fifty-one52fifty-two53fifty-three54fifty-four55fifty-five56fifty-six57fifty-seven58fifty-eight59fifty-nine60sixty61sixty-one62sixty-two63sixty-three64sixty-four65sixty-five66sixty-six67sixty-seven68sixty-eight69sixty-nine70seventy71seventy-one 72seventy-two 73seventy-three 74seventy-four 75seventy-five 76seventy-six77seventy-seven 78seventy-eight 79seventy-nine 80eighty81eighty-one第82eighty-second 第83eighty-third第84eighty-fourth 第85eighty-fifth第86eighty-sixth第87eighty-seventh 第88eighty-eighth 第89eighty-ninth第90ninetieth第91ninety-first第92ninety-second 第93ninety-third第94ninety-fourth 第95ninety-fifth第96ninety-sixth第97ninety-seventh 第98ninety-eighth 第99ninety-ninth第100onehundredth 82eighty-two 83eighty-three 84eighty-four 85eighty-five 86eighty-six87eighty-seven 88eighty-eight 89eighty-nine 90ninety91ninety-one 92ninety-two 93ninety-three 94ninety-four 95ninety-five 96ninety-six97ninety-seven 98ninety-eight 99ninety-nine 100onehundred1－100的序数词分为四个类。

各位家长：
从本学期的第二单元起，孩子开始接触英语的序数词。
之前孩子接触的数词都是基数词，现阶段可能会有一些混淆与不熟练。
本学期必须掌握的序数词为【第1-第12】，其中【第1、2、3】尤其重要，必须会背会默。
不过在今后的各种练习题中，可能会出现12以外的序数词，为了方便孩子查阅使用，我整理了1-100的序数词，并列出对应基数词。
怕有误会，再说明一次：并不需要100个序数词全背出或默出，有要求的只有前12，其他的只要用时查看即可（但是对之后的构成规律必须有所了解）
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。
