名词所有格的构成、用法及练习名词在句中表示所有关系、所属关系、动作执行者及动作承受者等意义时常需用所有格形式。
名词所有格也称为属格、主格，它主要包括's所有格、of所有格和双重所有格三种表现形式。
名词所有格的用法：1.0 名词+ ’s （主要用于有生命的事物或自然界独一无二的某些空间和时间名词的所有格）1.1 单数名词和不以-s结尾的复数名词在词尾加’s构成所有格，例如：e.g. Jimmy’s book（吉米的书）Jane’s schoolbag（简的书包）Mark’s room （马克的房间）Qi anqian’s mother （倩倩的妈妈）Children’s Day(儿童的节日、六一儿童节)M en’s R oom 男厕所Wuhan’s summer is very hot. (武汉的夏天非常热。
)Qianqian ’s math is very good.(倩倩的数学很好。
)1.2 复数名词以-s结尾的只需要加’ 构成所有格。
e.g. Twins’ father is Mr. Brown. (双胞胎的爸爸是布朗先生。
)Girls’ favorite food is ice-cream. (女孩们最喜欢的食物是冰激凌。
)the workers’ struggle工人的斗争2.0 名词+of +名词如果名词是无生命的，我们通常就要用名词+of +名词的结构来表示所有关系。
例如：e.g. A bag of mine= my bag (我的书包)The name of the girl =the girl’s name (女孩的名字)The window of the bedroom = the bedroom’s window(卧室的窗户)3.0 特殊所有格若一样东西为两人共有，则后一个人名用所有格；如果不是两人共有，而是各有各的，则两个名词都用所有格，且其后名词应为复数。
例如：e.g. This is Tom and Jim’s room. 这是汤姆和吉姆共有的房间。
These are Tom’s and Jim’s rooms. 这些是汤姆和杰森各自的房间。
an hour and a half’s walk （步行一个半小时的路程）4.0 's所有格所修饰的词的省略现象4.1 表示诊所、店铺或某人的家等地点名词，其名词所有格后的被修饰语常常省略。
例如：e.g. I met her at the doctor's（office）．我在诊所遇见了她。
He has gone to the tailor's（shop）．他到服装店去了。
She went to Mr．Black's（house）yesterday．她昨天到布莱克先生家去了。
4.2 名词所有格所修饰的词，如果前面已经提到过，往往可以省略，以免重复。
例如：e.g. Whose pen is this？It's Tom's．这是谁的钢笔？是汤姆的。
The bike is not mine，but Wang Pinpin's．这辆自行车不是我的，是王品品的。
4.3 在复合名词或短语中，’s 加在最后一个词的词尾。
e.g. a month or two’s absence4.4 作为一个整体的词组，一般在最后一个词的词尾加’s。
e.g. an hour and a half’s walk （步行一个半小时的路程）Carol and Charles’ boat （卡咯和查尔斯两人共有的船）4.5 不定代词后接else , 所有格放在else 上。
e.g. somebody else’s bag4.6. 下列情况可以将’s 所有格中的名词省略。
4.6.1 名词所有格所修饰的词, 如果前面已经提到，往往可以省略，以免重复。
e.g. This notebook is not mine, nor John’s, nor Peter’s.这个笔记本不是我的，也不是约翰和比特的。
The dictionary isn’t mine, but Jenny’s.这本词典不是我的，而是珍妮的。
4.6.2 名词所有格后面有指地点等的名词时, 有的在习惯上可以省略。
（同4.1）e.g. Before Christmas, there were lots of customers at the Richarsons’.the doctor’s（office）医生的诊所my uncle’s（house）我叔叔的家4.7 起修饰作用的名词，如不表示所有关系，通常不用’s。
e.g. room number tooth brush5.0 双重所有格及其用法's所有格和of所有格两种所有格形式结合在一起，构成"of＋所有格"形式，即双重的所有格。
它通常表示部分观念，即全体中的一部分，在意义上与"one of．．．"相似，它主要修饰of短语之前的那个名词。
此外，双重所有格与指示代词连用时，常带有感情色彩，如赞赏、不满、厌恶等。
它的主要形式如下：5.1 名词＋of＋名词性物主代词。
例如：e.g. a good friend of mine 我的一个好朋友an interesting story of his 他的有趣的经历5.2 名词＋of＋'s所有格。
e.g. He is a friend of my sister's．（＝one of my sister's friends）他是我姐姐的一个朋友Look at that long nose of Jack's．看杰克的那个长鼻子。
（感情色彩）试比较：a picture of Xiao Zhang 小张（本人）的照片a picture of Xiao Zhang's 小张（具有的照片中）的一张照片5.3 不定冠词、数词、某些不定代词（some，any，many，no，few等）以及which等限定词，一般不与形容词性物主代词或's所有格等一起放在名词前修饰名词，而采用of所有格或双重所有格形式。
例如：e.g. most of the students 学生中的大多数three of them 他们中的三个人I have read some books of his．我读过他的一些书Which book of Qiong Yao's have you read？你读过琼瑶的哪一本书？6.0 's所有格、of所有格和双重所有格三者之间的细微区别请仔细比较下面三句话：5.41 She is Mary's brother's friend．5.42 She is a friend of Mary's brother．5.43 She is a friend of Mary's brother's．5.41 句用的是's所有格，侧重说明她和Mary的哥哥是朋友关系，突出friend一词。
5.42 句用的是of所有格，侧重说明她和Mary的哥哥是朋友关系，强调突出了Mary's brother。
5.43 句用的是双重所有格，侧重说明Mary哥哥的朋友不止是一个，她只是其中的一个。
