一、名词词尾加 's 的所有格
1.一般情况在名词后加 's
例如：

2.在以 s 结尾的名词 ( 包括以 s 结尾的复数名词 ) 后面，只加 ' 。

如果复数名词不是以 s 结尾的，末尾也要加 's 。

例如：
Today is September 10th, Teachers' Day. 今天是九月十日，。

Children's Day is ing, I should buy something new for my
son.儿童节马上就要到了，我应该为我的儿子买一些新东西。

3.表示词组内的并列名词各自的所有关系时，须在各个名词后加's; 如果一个东西为两个人或者两个以上的人共同拥有，只在最后一个名词后面加 's 。

例如：
They are John's and Kate's rooms. Howbeautiful they are!这是约翰和凯特的房间。

它们( 指房间 ) 太漂亮了 !
He is Lily and Lucy's father.他是莉莉和露西的爸爸。

4.表示某人的家、店铺等的所有格，一般可以省略它后面所
修饰的名词。

例如： My father and I will have dinner at the Johnson's (home ) 。

我爸爸和我将要去约翰逊的家吃晚饭。

We will have our hair cut at the barber's(shop) tomorrow afternoon.明天下午我们要去理发店理发。

5.有些指时间、距离、国家、城镇等的名词，也可以加 's 构成所有格。

例如：
There is something important in today's newspaper.今天的报纸上有一些重要的东西。

It's about ten minutes' walk from school to our home every day.每天从学校到我们家步行大约需要十分钟。

6.英语名词所有格修饰的词，如果前面已经提到过，后面则可以省略，以防止重复。

例如：
This is not Dick's dictionary, but is Tom's.这不是迪克的字典，但是是汤姆的。
