He likes English.（He代替Tom作主语） 例：The book is interesting. It is my favourite.（It代替the book作主语） 人称代词主格有明确的人称和数的区分，需对应使用 人称代词（主格）-分类与例句 人称 主格形式 指代对象 例句 第一人称单数 I 说话人自己 I am a middle school student. 第一人称复数 We 说话人及同伴 We are in Class 1. 第二人称单/复数 You 听话人（单数/复数） You are my good friend. / You are all kind. 第三人称 He 男性 He is my brother. 第三人称单数 She 女性 She is a teacher. 第三人称单数 It 事物/动物/天气等 It is a dog. / It is sunny. 第三人称复数 They 复数的人/物 They are my classmates. 物主限定词-核心定义与功能 物主限定词（又称形容词性物主代词）表示所属关系 核心功能：修饰名词，说明名词的归属，回答“谁的”的问题 关键特征：后面必须接名词，不能单独使用 例：This is my book.（my修饰book，表“我的书”） 例：Her favourite subject is Maths.（her修饰favourite subject，表“她的最喜欢的科目”） 人称代词主格与物主限定词对应表 人称代词（主格） 物主限定词 例句 I my I am Lucy. My bag is red. We our We are students. Our classroom is big. You your You are nice. Is this your pen? 记忆技巧：主格表“谁”，物主限定词表“谁的”，一一对应不混淆 He his He is Tom. His bike is new. She her She is Lily. Her dress is beautiful. It its It is a cat. Its name is Mimi. They their They are friends. Their homes are near. 人称代词与物主限定词-用法对比 1. 功能不同：人称代词主格作主语，物主限定词修饰名词、表所属； 2. 能否单独使用：人称代词主格可以单独作主语，物主限定词必须接名词，不能单独使用； 错误示例1：My is a student.（正确：I am a student.，my不能单独作主语）； 错误示例2：She bag is blue.（正确：Her bag is blue.，she是主格，不能修饰名词）。 语法易错点提醒（人称代词与物主限定词） 1. 主格与物主限定词混用：He book is new.（正确：His book is new.）； 2. 物主限定词后漏接名词：This is my.（正确：This is my pen.）； 3. it的物主限定词错误：It's name is Lucky.（正确：Its name is Lucky.，its表所属，it's是it is缩写）； 4. 第三人称复数混淆：She are my friends.（正确：They are my friends.）； 5. your的单复数误用：You is my teacher.（正确：You are my teacher.，you单复数均用are）。 小练习（一）-人称代词主格填空 用适当的人称代词主格（I/we/you/he/she/it/they）填空 1. ___________ am a student. ___________ go to school by bike.； 2.
