英语中1-100的序数词.doc

(完整版)英语中1-100的序数词各位家长: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1100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21twentyfirst第22twenty-second第23twentythird第24twenty-fourth第25twenty-fifth第26twenty-sixth第27twenty-seventh第28twenty-eighth第29twentyninth第30thirtieth第31thirty-first第32thirty-second第33thirty-third第34thirty-fourth第35thirty-fifth第36thirty-sixth第37thirtyseventh第38thirty-eighth第39thirtyninth第40fortieth第41fortyfirst第42forty-second第43fortythird第44fortyfourth第45fortyfifth第46fortysixth第47forty-seventh第48fortyeighth第49forty-ninth第50fiftieth第51fiftyfirst第52fiftysecond第53fiftythird第54fifty-fourth第55fifty-fifth第56fiftysixth第57fiftyseventh第58fifty-eighth第59fiftyninth第60sixtieth第61sixtyfirst第62sixtysecond第63sixty-third第64sixty-fourth第65sixtyfifth第66sixtysixth第67sixtyseventh第68sixty-eighth第69sixtyninth第70seventieth第71seventy-first第72seventy-second第73seventy-third第74seventyfourth第75seventyfifth第76seventysixth第77seventy-seventh第78seventyeighth第79seventy-ninth第80eightieth第81eightyfirst第82eighty-second第83eighty-third第84eighty-fourth第85eighty-fifth第86eighty-sixth第87eightyseventh第88eightyeighth第89eightyninth第90ninetieth第91ninetyfirst第92ninety-second第93ninety-third第94ninety-fourth第95ninety-fifth第96ninetysixth第97ninetyseventh第98ninetyeighth第99ninetyninth第100onehundredth1100基数词：1one2two3three4four5five6six7seven8eight9nine10ten11eleven12twelve13thirteen14fourteen15fifteen16sixteen17seventeen18eighteen19nineteen20twenty21twenty-one22twentytwo23twentythree24twentyfour25twenty-five26twenty-six27twentyseven28twentyeight29twenty-nine30thirty31thirtyone32thirtytwo33thirtythree34thirty-four35thirtyfive36thirtysix37thirtyseven38thirty-eight39thirtynine40forty41forty-one42forty-two43forty-three44forty-four45forty-five46fortysix47forty-seven48fortyeight49fortynine50fifty51fiftyone52fiftytwo53fifty-three54fiftyfour55fiftyfive56fiftysix57fiftyseven58fiftyeight59fifty-nine60sixty61sixtyone62sixty-two63sixtythree64sixtyfour65sixty-five66sixty-six67sixtyseven68sixtyeight69sixtynine70seventy71seventyone72seventytwo73seventy-three74seventyfour75seventyfive76seventysix77seventyseven78seventy-eight79seventynine80eighty81eighty-one82eightytwo83eightythree84eighty-four85eightyfive86eightysix87eighty-seven88eightyeight89eightynine90ninety91ninetyone92ninetytwo93ninety-three94ninetyfour95ninetyfive96ninety-six97ninetyseven98ninetyeight99ninety-nine100onehundred1100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eightyseventh(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。精心整理
