“名词+’s ” 所有格
形容词性物主代词
“名词+'s”所有格
1) 单数名词后加“ 's ”（以-s结尾的人名后加“ ' ”或“ 's ”）。
my sister's book 我姐姐的书
2) 以-s结尾的复数名词只加“ ' ”，不以-s结尾的复数名词通常加“ 's ”。
the three girls' father 这三个女孩的父亲
the three children's father 这三个孩子的父亲
“名词+'s”所有格主要用于有生命的名词的所有关系。
3) 表示几个人共有，仅在最后一个人的名字后加“'s”；表示各自所有时，应在各个名字后加“'s”。
Mary and Jane's car 玛丽和简的汽车
Mary's and Jane's cars 玛丽和简的汽车
（她们共有的汽车）
（她们各自的汽车）
of 所有格
1) of 所有格多用于表示无生命事物的名词的所有关系。

2) of 所有格也可用于表示人和其他有生命的名词的所有关系。
the name of her cat 她的猫的名字
the girl's new dress = the new dress of the girl 这个女孩的新连衣裙
3) 's所有格和of 所有格有时可以互相转换。
序数词
表示人或事物先后顺序的数词叫序数词。序数词大多数是由基数词变化而来的，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。
八去t，九去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
two thirds 三分之二
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。
