名词所有格表示所属关系，即表示某物是“谁的”。名词所有格常见的结构有三种：一、’s所有格

表示有生命的人或动物的名词所有格，单数名词和不以s结尾的复数名词一般在词尾加“’s”，以s结尾的复数名词在词尾只加“’”。e.g.Kate’scat凯特的猫

无生命事物名词的所属关系,一般常用“of

＋名词”来表示，即of所有格。如：

amapofChina一幅中国地图，

thelegsofthetable桌子的腿

of所有格与’s所有格有时可以互换,不过要注意它们物主的位置不同。如：

猫的名字是咪咪。

ThenameofthecatisMimi．

(of结构,物主thecat在后)

Thecat’snameisMimi．

(’s结构,物主thecat在前)特殊所有格（to的所有格<一般有唯一性>）1．门的钥匙：
