物主代词
Grammar 1 物主代词
形容词性物主代词
名词性物主代词
（形物代）
（名物代）
物主代词：表示所有关系的代词
人称 第一人称 第二人称 第三人称 我的 我们的 你（们）的 他的 她的 它的 他们的/
她们的/
它们的
形物代 my our your his her its their
名物代 mine ours yours his hers its theirs
口诀：物主代词有两种， 添个s形变名，
his,its不用变，my变mine要记清。
1.形物代起形容词的作用，用在名词前，后面必须有名词；
e.g: This is my book.
2.名物代起名词作用，其作用相当于一个名词，只能单独使用，
不加名词； e.g: This book is mine.
3.名物代=形物代+名词
This is my book. That is yours.
4.名物代可放在句末，形物代不可放句末。
= your book.

顺口溜:用形或用名，全凭后决定；有名则用形，无名则用名。
物主代词：替换
some作形容词时，意为“一些；某些”；
作代词时，意为“有些(人或物)”。
some用于肯定句中，any用于否定句和疑问句中。如：
①I have some apples. 我有一些苹果。
②Do you have any apples？你有苹果吗？
③I don't have any erasers. 我没有橡皮。
但当希望对方给出肯定的回答时，疑问句中也用some。
如：
①Would you like some apples
你想要些苹果吗？
②Can I ask you some questions
我可以问你一些问题吗？
考点 1 some的用法
this是指示代词，它的意思是“这个”，this一般指时间和距离比较近的人或者事物。
可以指代单数可数名词和不可数名词。
例如：This is a big tree. 这是一棵大树。
This is a piece of glass. 这是一块玻璃。
this 修饰单数可数名词时，名词前面不可以再有形容词性物主代词、冠词、所有格等修饰。
例如：This book is not mine. 这本书不是我的。
This girl is my sister. 这个女孩儿是我姐姐。
this 的复数是these。
例如：This is a pen. 这是一支钢笔。
These are pens. 这些是钢笔。
拓展：this 与that
this指代离说话人较近的人、物、时间，也可以指说过或者做过的事。打电话时可以用来介绍自己是谁。
例如：This is a beautiful garden. 这是一个漂亮的花园。
Hello, this is Jim speaking. 你好，我是吉姆。
that 是远指，指离说话人较远的人、物、时间，也可以在打电话时用来询问对方是谁。
