译林版七年级下册 Unit 4 名词所有格 & 形容词性/名词性物主代词知识点梳理+分层专项练习 一、知识点梳理 （一）名词所有格 作用：用来表示人、事物之间的所属拥有关系。 1. 普通单数名词（含人名）：词尾直接加 `’s` 例：the woman’s daughter 这位妇女的女儿；Tom’s sister 汤姆的姐姐 以`s`结尾的人名两种写法均可：Charles’s pen = Charles’ pen 查尔斯的钢笔 2. 以s结尾的复数名词：词尾只加撇号 `’` 例：the twins’ parents 双胞胎的父母；the students’ hometown 学生们的家乡 3. 不以s结尾的不规则复数名词：词尾加 `’s` 例：Children’s Day 儿童节；the People’s Republic of China 中华人民共和国 （二）形容词性物主代词、名词性物主代词 功能：表达所属关系 1. 基础用法示例 - This is my book. 这是我的书。（形容词性物主代词+名词） - This book is mine. 这本书是我的。（名词性物主代词，单独使用） - These are our books. 这些是我们的书。 - These books are ours. 这些书是我们的。 2. 两条核心规则 ① 形容词性物主代词后面必须搭配名词，不能单独使用； ② 名词性物主代词 = 对应的形容词性物主代词 + 名词，可独立充当句子成分； ③ 特殊说明：`its`既可以作形容词性物主代词，也可以作名词性物主代词。 物主代词对照表 分类 单数 复数 第一人称 第二人称 第三人称 第一人称 第二人称 第三人称 形容词性物主代词 my your his her its our your their 名词性物主代词 mine yours his hers — ours yours theirs > 备注：it 没有名词性物主代词形式，表格内对应位置标注“—”。 二、分层梯度练习题 基础夯实一：名词所有格变形填空 按照要求改写名词所有格形式 1. the girl ______ bag（这个女孩的书包） 2.
