6、名词所有格名词所有格一般是在名词后面加上"'s",表示"某某人的……",称为所属关系。名词所有格都有哪些形式呢?是"'s","of"和"双重所有格"。名词所有格多用于表示有生命的名词的所属关系,此时要用"'s"表示。但其构成和用法又分为以下六种情形:①一般情况下,是在单数名词的词尾直接加"'s"。例如:Jim's football吉姆的足球Kate's cat凯特的猫②.以-s结尾的复数名词,只能在词尾加'。比如:the teachers'chairs老师们的椅子the students'books学生们的书③不以-s结尾的不规则复数名词,还得在词尾加's'。你看:Children's Day儿童节 Women's Day 妇女节men's shoes男鞋 Teachers' Day 教师节women's clothes女士服装④.若表示两人各自所有的两个东西,则应在两个名词后面都加上's',且后接复数名词;若表示两人共同所有的一个东西,则只能在后面那个名词后面加上's',且后接单数名词。请比较:Tom's and Mike's room s汤姆和迈克的房间(两人各有一间,共两间,不是共同拥有)
Tom and Mike's room汤姆和迈克的房间(两人共同拥有的一间房间)
表示无生命的所属关系时,要用介词"of"所构成的短语来表示。the legs of the tablethe hands of the clockthe name of the hilla map of Chinaa photo of my family Here are two photos of my family
