Unit1 A New Start人称代词讲解与练习 一、核心语法精讲（主格、宾格、形容词性物主代词,名词性物主代词） 1. 人称代词表格（必背） 人称 主格（作主语，句首 / 动词前） 宾格（作宾语，动词 / 介词后） 形容词性物主代词（后接名词） 名词性物主代词（单独使用，相当于「形容词性物主代词 + 名词」） 第一人称单数 I 我 me 我 my 我的 mine 我的 第二人称单数 you 你 you 你 your 你的 yours 你的 第三人称单数 he /she/it 他/她/它 him /her/it 他/她/它 his /her/its 他的/她的/它的 his /hers/its 他的/她的/它的 第一人称复数 we 我们 us 我们 our 我们的 ours 我们的 第二人称复数 you 你们 you 你们 your 你们的 yours 你们的 第三人称复数 they 他们/ 她们/它们 them 他们/她们/它们 their 他们的/她们的/它们的 theirs 他们的/她们的/它们的 2. 三大用法核心规则（解题关键） ① 主格：作句子主语，放在句首、be动词/实义动词之前 例：She is a new student. 她是一名新学生。 They are my friends.他们是我的朋友。 ② 宾格：作宾语，放在动词、介词后面 例：Let me help you. 让我帮你。 / Look at them. 看他们。 The dog followed you. 狗狗跟着你。 ③ 形容词性物主代词：后面必须接名词，表“谁的” 例：This is my classroom. 这是我的教室。 These are his favorite toys.这些是他心爱的玩具。 ④ 名词性物主代词：可单独使用，后面不能加名词，本身等同于「形容词性物主代词 + 名词」，翻译仍为 “…… 的（东西）” 核心区分口诀：后有名词用形物代，无名词单独用名物代 例句对比（直观区分两类物主代词） *This is my classroom.（my形容词性物主代词，后接名词classroom） = This classroom is mine. （mine 名词性物主代词，单独使用，mine = my classroom） *These are his favorite toys.（his 形容词性物主代词,后接名词 toys） = These favorite toys are his.（his 名词性物主代词,单独使用,his = his toys） 经典例句 The blue pen is hers. 这支蓝色钢笔是她的。（hers = her pen） This big room is ours. 这间大教室是我们的。（ours = our room） That small ball is theirs. 那个小球是他们的。（theirs = their ball） 必考易错点 1.名词性物主代词本身已经包含 “XX 的某物” 含义，后面绝对不能再接名词； ❌ This book is mine book.（错误） ✅ This book is mine.（正确） 2.his /its 两种形式拼写完全一致，只能靠后面有无名词区分用法； 3.常放在句末作表语，也可放在句首作主语： Ours is a clean classroom. 我们的教室很干净。（Ours = Our classroom） 3. 高频易错点 1.形容词性物主代词不能单独使用，后必须加名词； 2.介词后一律用宾格（at/for/with/to/of +宾格）; 3.名词性物主代词后不能再加名词,名词性物主代词=形容词性物主代词+名词 【配套练习】 大题一：用所给词的正确形式填空 根据句意，用括号内人称代词的正确形式填空。 1. ________ (I) am a new student in this school. 2.
