   1、 名词所有格表示所属关系,相当于物主代词,在句中作定语、宾语或主语。其构成法如下:


  (1)表示人或其它有生命的东西的名词常在词尾加’s。如:Childern’s Day(儿童节), my sister’s book(我姐姐的书)
  (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:Teachers’ Day(教师节) .如果复数名词不是以s结尾的,末尾也要加's。例如 Children's Day:
  (3)有些表示时间、距离以及世界、国家、城镇等无生命的名词,也可在词尾加’s. 如:today’s newspaper(今天的报纸), ten minutes’ break(十分钟的课间休息)
  (4) 无生命的东西的名词,一般可用介词of短语来表示所有关系。如: A key 2 of the door
  2、[注解]:① ‘s还可以表示某人的家或者某个店铺,如:my aunt’s(我阿姨家), the doctor’s(诊所)
  ②  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:Lucy ‘s and Lily’s bedroom  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,如:Lucy and Lily’s bedroom(露西和丽丽合住的卧室).
  ③ “of+名词所有格/名词性物主代词”,称为双重所有格,如:a friend of my father’s(我父亲的一位朋友), a friend of mine(我的一位朋友)
