2、t，us，you，them此外，还有所有格形式。属格：my，mine，your，yours，his，her，hers，its，our，ours，their，theirs 属格又可分为两类：一类是形容词性物主代词（my，your，his，her，its，our，their）即 “物主限定词”；另一类是名词性物主代词（mine，yours，his，hers，ours，theirs），即 “物主代词”。人称代词第一人称第二人称第三人称单数复数单数复数单数复数主格Iweyouyoushe he itthey宾格meusyouyouher him itthem物主代词形物代myouryouryourhe

3、r his itstheir名物代mineoursyoursyourshers/his/itstheirs人称代词用法：（1） 人称代词主格：做主语，表示谁怎么样了，干什么了。I am a teacher.You are student.He is a student , too.We/You/They are student.（2） 人称代词宾格：作宾语，表示动作行为的对象，一般放在动词的后面。Give it to me.Lets go.(lets=let is)（3） 形容词性物主代词（my/your/his/her/its/our/their）+名词。（4） 而名词性物主代词（mine/

4、yours/his/hers/its/ours/theirs）则相当于形容词性物主代词+名词，故其后不必加名词。如：-Is this your book?-No,it isnt,its hers(her book).its Jims,its Toms.名词性物主代词=形容词性物主代词+名词为避免重复使用名词，有时可用“名词性物主代词”来代替“形容词性物主代词+名词”的形式。例：My bag is yellow, her bag is red, his bag is blue and your bag is pink. 为避免重复使用bag，可写成My bag is yellow, hers i
