“名词+’s ”所有格

“名词+'s”所有格主要用于有生命的名词的所有关系。意为“...的”
序数词：表示人或事物先后顺序的数词。
1-3的序数词first / second / third与基数词差别很大，应逐一记忆。
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。
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。
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。
注意：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。
序数词的用法：
序数词前一般要加定冠词the。
e.g.I live on the second floor. 我住在二楼。
序数词常用来修饰名词，但当名词前有形容词性物主代词等限定词时，序数词前不用定冠词。
e.g.Today is my thirtieth birthday. 今天是我的三十岁生日。
序数词前有时也可加不定冠词a / an，这时表示的是表示在原有基础上的“又一个，另一个”。
e.g. a second time 再来一次
