序数词表
序数词
表示人/事物先后顺序的数词叫序数词。它的作用相当于名词或形容词，可作主语、宾语、定语或表语。序数词往往与定冠词the连用。
语法概述
序数词的构成
1) 1-3的序数词first / second / third与基数词差别很大，应逐一记忆。
2) 4-19的序数词是在相应基数词后加上后缀-th。注意fifth，eighth，ninth，twelfth的特殊性。
3) 整十的序数词，通常是把相应的整十的基数词词尾的y变成ie，再加-th。
forty fortieth
fifty fiftieth
4) 表示“第几十几”，只需把个位数的基数词变为序数词，十位数不变。
twenty-one twenty-first
thirty-four thirty-fourth
5) 序数词的缩写形式是在阿拉伯数字后直接加上序数词的最后两个字母。
first = 1st
second = 2nd
third = 3rd
ninth = 9th
twentieth = 20th
基变序，有规律，多数词尾加-th。
一二三，特殊记，词尾字母t, d, d。
八加h，九减e，f 来把 ve替，然后再加-th。
遇到整十需注意，变 y为ie，然后再加-th。
若是遇到几十几，只变个位数字就可以；
中间连字符“-”，千万别忘记。
巧学妙记
序数词的用法
1) 序数词前一般要加定冠词the。
2) 序数词常用来修饰名词，但当名词前有形容词性物主代词名词所有格或指示代词等限定词时，序数词前不用定冠词。
I live on the second floor. 我住在二楼。
Today is my ninth birthday. 今天是我的九岁生日。
3) 表示分数时，分子用基数词，写在前面；分母用序数词，写在后面。当分子大于1的时候，表示分母的序数词要+s。
one fifth 五分之一
4) 序数词前有时也可加不定冠词a / an，这时表示的不再是具体范围内的“第几”，而是表示在原有基础上的“又一个，另一个”。
I think you must do it a second time.
我觉得你必须再做一次。
