一般过去时的几种句型

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, Grade

7. (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？
