一、名词所有格的构成
名词所有格“s”主要用来表示有生命的名词的所属关系。所以它常用在姓名、人称、不定代词、集体名词和高等动物等这样的名词后面。
1、单数名词
直接在词尾加“ ‘s ”。比如：
my sister’s boyfriend
the person’s choice
a woman’s intuition 女人的直觉
the actress’s boyfriend
2、复数名词
a）不以-s结尾的名词，直接在词尾加“ ‘s ”。例如：
the Children’s Day
the children’s books
women’s wear
b)以-s结尾的名词，在词尾加“ ‘ ”。例如：
her friends’ money
The stars’ concert was a sell-out。这些明星们的音乐会门票已经售完。
3、复合名词
在最后一个词的词尾加“ ‘s ”。例如：
my father-in-law’s company
everyone else’s viewpoints
Henry the Eighth’s wives 亨利八世的妻子们
the Prince of Charles’s car 查理王子的车
the President of America’s cecretary
My brother-in-law’s cousin is a singer 我姐夫的表弟是一位歌手
4、并列名词
对于and连接的并列名词，当表示“共有”时，只需在最后一个名词的词尾加“ ‘s ”；若表示“各自所有”，则须在每个名词的词尾加“ ‘s ”。
John and his wife’s bank savings 约翰和他妻子的共同存款
John’s and his wife’s bank savings 约翰和他妻子各自的存款
二、 ‘s所有格的逻辑关系
1、所属关系
my father-in-law’s company
2、主谓关系
How will Bhutto’s death affect the world? => Bhutto died
the visitor’s departure => the visitor departed
the teacher’s request => the teacher request
Britain’s decision => Britain decided
3、动宾关系
Bhutto’s assassination rocks Pakistan => assassinate Bhutto
the children’s education => educated the children
the boy’s punishment => punished the boy
4、同位关系
For Washington, Bhutto’s loss is incalculable. => the loss of Bhutto
5、表示时间或距离
tomorrow’s weather
a hard day’s work
a week’s holiday
a month’s salary
My birthday is in two weeks’ time.
6、表示重量或价值等度量
two pounds’ weight
two dollars’ worth of sugar
ten dollars’ worth of meat
三、名词所有格的省略
1、避免名词重复
The bike is mine, not Michael’s.(= Michael’s bike)
The room is my room and that is my sister’s. (=my sister’s room)
2、表示店铺或教堂
at the baker’s. (=baker’s shop)在面包店
at the butcher’s. (=butcher’s shop)在肉店
at the chemist’s. (=chemist’s shop)在药店
at the florist’s. (=florist’s shop)在花店
at the dentist’s. (=dentist’s clinic)在牙医诊所
at the doctor’s. (=doctor’s clinic)在医生的诊所
I’m going to the dentist’s tomorrow afternoon.
I want to pay a visit to the St. Paul’s(=St. Paul’s Cathedral).我想去拜访一下保罗大教堂
3、表示某人的住宅
人名后的所有格省去名词时，表示某人的住宅。比如：
go to my sister’s.
I called at my uncle’s yesterday.我昨天拜访了我叔叔家
