人称代词用来代替表示人或事物的名词，以便不再重复使用名词。

1）人称代词的主格在句子中作主语用法举例：1.My name is Millie. I live in Beijing. ( I代自己, Millie )2. Sandy, do you know where Mr Wu is? ( you代Sandy )3. Simon loves football. He is a member of the football team.4. Millie loves Eddie. She looks after him every day. (she 代Millie)5. This book is very interesting. It is about cartoons. (it 代this book)6. I am Daniel and this is Amy. We are in Class 1, Grade7. (we 代替Amy and I)2）人称代词的宾格在句子中作宾语(放在动词后面或者介词后面)1.Tell me the answer, please.(动词后面)2.Let’s go.(=let us go) (动词后面)3. Look at him. He is funny! (介词后面)物主代词的定义：物主代词实际上是人称代词的所有格形式。

物主代词可以分为形容词性和名词性两种。

形容词性物主代词一定要后接名词（如：This is my book. 这是我的书。

），名词性物主代词可以独立使用，无需后接名词（如：This book is mine. 这本书是我的。

）。

3) 形容词性物主代词一般位于名词前，用作定语，限定该名词的意义This is my book.4) 名词性物主代词的句法功能a. 作主语，例如：May I use your pen? Mine is broken.（mine=my pen）我可以用一用你的钢笔吗？我的坏了。

b. 作宾语，例如：There is something wrong with my bike. Can I use yours? (Yours=your bike) 我的自行车坏了，能用你的吗？人称代词和物主代词练习一、用适当的人称代词和物主代词填空1. ________（他）often helps ________（我们）with our lessons.2.
