代词是代替名词的词类。

大多数代词具有名词和形容词的功能。

英语中的代词，按其意义、特征及在句中的作用分为：人称代词、物主代词、指示代词、反身代词、疑问代词、不定代词。

一．人称代词：代替具体人名的词叫人称代词。

它有一、二、三人称与单数、复数及性别之分，还有主格与宾格之分。

人称代词有人称、数和格的变化：（1）Who’s Kate? 凯特是谁？She’s my friend. 她是我的朋友。

注：she代替上文中的Kate，而不能再用Kate来重复回答：Kate is my friend. （2）Li Lei is a boy. He’s twelve. 雷是个男孩，他十二岁。

注：he代替前句中的雷。

（3）Look at that bird. It is Polly. 看那只鸟，它是波利。

注：it代替前句中的that bird。

（4）Who’s it?（门外有敲门声）谁呀？It’s me. 是我。

人称代词的用法★1）人称代词的主格在句子中作主语。

例如：He is student. 他是一个学生。

★2）人称代词的宾格在句子中作宾语或介词宾语，但在口语中也能作主语补语.) 例如： I saw her with them at least, I thought it was her.我看到她和他们在一起，至少我认为是她。

（her做宾语，them做介词宾语，her做主语补语）-- Who broke the vase? --谁打碎了花瓶？-- Me. --我。

（me做主语补语= It's me.）难点：主格和宾格的区别用法主格做句子主语，而宾格作为动词或者介词的宾语。

(动宾结构或者介宾结构)例如：Give it to me. （宾格）I love you. （主格）3). 并列人称代词的排列顺序①单数人称代词并列作主语时，其顺序为：第二人称－> 第三人称－> 第一人称，即you－> he/she; it -> I。

例如：You, he and I should return on time.②复数人称代词作主语时，其顺序为：第一人称－> 第二人称－> 第三人称，即we －>you－>they。

巩固练习：用适当的人称代词填空。

（前后两句人称与数保持一致）（1）My name is Amy. ________ am Amy.（2）Our names are Amy and Gina. ________ are Amy and Gina.（3）His name is Tim. _______ is Tim.（4）Her name is Alice. ______ is Alice.（5）Their names are Tim and Alice. ________ are Tim and Alice.（6）Your name is Li Peng. _______ are Li Peng.（7）Your names are Li Peng and Li Lei. _______ are Li Peng and Li Lei.（8）Its name is Mimi . _________ is Mimi.★代词it的用法①指代前面提到过的事物。

如： The book on the desk is not mine. It is Jim's.②指代指示代词this或that. 如： ---What's that? ---It is a pen.③指代婴儿或不明身份的人. 如：Someone is knocking at the door. Please go and see who it is .④指代时间或季节如：---What is the time now? ---It's ten o'clock.⑤指代天气如：---What's the weather like today? ---It's sunny.⑥指代距离如：How far is it from your school to your home?⑦用作形式主语，常用语下列句型中例句: It is easy for me to finish the homework.It is important for us to work hard.例句：It’s time for eating lunch.It's time to get up /for lunch/that we went home.二、物主代词表示所有关系的代词叫物主代词，可分为形容词性物主代词和名词性物主代词。

形容词性物主代词一般放在所修饰名词的前面，同时它们也有人称和数的变化。

形容词性物主代词的前后是不出现冠词的，这是在书写句子时最容易犯的错误。

如：my father, his desk, our room, their names, your aunt等。

用法形容词性物主代词起形容词作用，在句中只能作定语，也就是说它后面必须跟一个名词。

如：This is my bike. 这是我的自行车。

Miss Gao is our English teacher. 高小姐是我们的英语老师。

I don’t know her name. 我不知道她的名字。

即：形容词性物主代词＋名词【例】She is a student and name is Kate.A. sheB. herC. hersD. his名词性物主代词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 isn't, it's hers(her book).This book is mine.= This is my book.Jim's , Tom's, Maria's则是名词所有格。
