数字 序数词变化规则 例词
1、2、3 特殊记 one →first 第一 two → second 第二；Three →third 第三
4～19 基数词词尾加-th 特殊：five → fifth 第五； eight → eighth 第八； nine → ninth 第九twelve → twelfth 第十二
一般：four → fourth 第四
nineteen → nineteenth 第十九
20, 30,40, … 整十数的变化： -ty变为-tie再加th twenty → twentieth 第二十 thirty → thirtieth

探究三：序数词的构成和用法。
二、序数词的用法：
1. 序数词要加定冠词the。但当序数词前有物主代词(his, her…)、指示代词(this, that…)等修饰时，则不必再用the。如：
on the third floor 在三楼 on his twelfth birthday 在他十二岁生日这天
2. 序数词常用缩写形式，即“阿拉伯数字 + 个位序数词的后两个字母”。如：one → 1st; second→ 2nd; third → 3rd; twelfth → 12th; twenty-sixth → 26th
3. 序数词可表示日期“几月几日”中的“几日”。如: August 17th
8月17日 October 1st 10月1日
March is the third month of a year. 三月是一年中的第三个月份。

二、序数词的用法：
4. 序数词可以用来表示顺序、编号等，放在名词的前面
eg：the fifth lesson第五课
基数词也可以表示编号：Lesson Five; Class Eight; Class Seven
5. 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
6. 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。

名词所有格表示所属关系，’s所有格是其中的一种，意为“……的”。
名词所有格构成规则
单数名词 加’s
复数名词 不以-s结尾 加’s
以-s结尾 加’
表示两个人共同拥有某物时，只需在后一个名词用’s所有格；表示两个人各自拥有某物时，则两个名词都得用’s所有格。 Presentation

探究四：名词所有格的构成和用法。
1）单数名词后直接加’s
如：Jim’s coat 吉姆的外套 Jeff’s mother 杰夫的妈妈
2）以s结尾的复数名词，只加“’”
如：Teachers’ Day 教师节 the twins’ books 双胞胎的书
3）不以s结尾的不规则的名词复数，加“’s”
如：Children’s Day 儿童节 men’s shoes 男式鞋
4)表示两者共同拥有时，只在最后一个名词后加’s
表示两者各自拥有时，要在每个名词后加’s
比较：Lucy and Lily's mother 露茜和莉莉的妈妈
Lucy‘s and Kate’s rooms 露茜和凯特的房间
注：表示时间、距离、国家、城市等无生命的名词也可以使用名词+'s所有格。如：a few years’ time 几年的时间 New Year’s Day 元旦节

注：以-s结尾的人名的所有格的构成是在其后加 ’ 或 ’s。 如James’或James’s
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。
a map of China 一幅中国地图
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。
the name of her cat 她的猫的名字
2) of 所有格有时候也用于有生命事物的名词的所有关系。
3. 双重所有格
(1) “of＋名词所有格”中的名词必须表示人，不能表示事物。因此，我们可以说：
　a play of Shakespeare’s 沙士比亚的一个戏剧
a friend of my wife’s 我妻子的一个朋友
但不能说a funnel of the ship’s或 a leg of a table’s，而且该名词必须是特指的，不能是泛指的。
我们可以说：
a friend of the doctor’s 这位医生的一个朋友
a novel of the writer’s 那位作者的一部小说
而不能说：
a friend of a doctor’s或 a novel of a writer’s。
