一、概述
代词是用来代替名词或名词词组的词，它的主要作用是为了避免重复。因此，在使用时必须在人称、数、性和格上与它们所替代的词保持一致。
Eg1. Mr. Wang is our English teacher. He is the most popular teacher in our school. His students admire him very much.
人称代词是指主要用来指代人或物的代词，表示“我”、“我们”、“你”、“你们”、“他”、“她”、“它”、“他们”、“她们”、“它们”等。人称代词有三个人称，每个人称又分为单数和复数、主格、宾格和所有格、以及反身代词等多种形式。
二、主格代词
主格代词在句中作主语。
Eg2. I am your English teacher. He is your Chinese teacher. She is your math teacher. We are all your teachers. You are our student. They are your classmates.
三、宾格代词
宾格代词在句中用作宾语，包括介词宾语。
Eg3. Please come to help us.
Eg4. Do not touch me.
Eg5. Don’t interrupt her.
Eg6. Please pass this cup of tea to him.
四、代词的所有格
所有格用来表示所用关系，说明物品的主人是谁。代词的所有格分为名词性物主代词和形容词性物主代词两种。
1．形容词性物主代词的用法
形容词性物主代词在句中作定语，其后必须跟名词才能在句中使用。形容词性物主代词在句中起相当于形容词的功能。
Eg7. My car is made in Germany.
Eg8. Is this your bag?
Eg9. His father is famous as a doctor.
Eg10. Their parents work in our country.
2．名词性物主代词的用法
名词性物主代词后不跟名词，可单独使用。它们在句中可做主语，宾语和表语。名词性物主代词在句中起相当于名词的功能。
Eg11. ---Whose computer is this? ---It is mine. (mine在句中作表语)
Eg12. ---Is this Lucy’s bike? ---No. Hers is smaller than this one. (Hers在句中作主语)
Eg13. ---Oh, my god! I forgot to take my English book. --- Use mine, Please. (mine在句中作宾语)
3．典型题典
1).用所给提示词的适当物主代词填空：
Eg14.This isn’t _______ (他)pen. It’s ______(我) pen. ______(我) is black. _______(他) is white.
2). 单项选择：下面这道题共有几项是错误的? 是哪几个选项？
Eg15. ________ car is the on the right of _______.
A. My … his B. His … mine C. Her … his D. Your … hers
E. their … yours F. Our … theirs G. Their … our F. His … hers
key: 一项， G
4．技巧：形容词性物主代词和名词性物主代词用法口诀：
形物代词后跟名，名物代词单独行。
五、人称代词并列使用时的排列顺序
1) 单数人称代词并列作主语时，其顺序为：二三一，即You, he\she and I (你他\她我)。
Eg16.You, he and I should return on time.
2) 复数人称代词作主语时，其顺序为：一二三，即We, you and they（我们、你们、他们）。
Eg17. We, you and they are brothers and sisters.
3) 注意：在下列情况中，第一人称放在前面。
在承认错误，承担责任时。
Eg18. It was I and John that made her angry. 是我和约翰惹她生气了。
4）即骄傲又谦虚的“我”：
“我”总是很骄傲，因为不管任何时候都要大写（I）；
同时“我”又总是很谦虚，因为当与其他人称并列使用时，“我”总是显示出很高的姿态，站在最后边。
