物主代词
在本模块中，我们会学到名词性物主代词。物主代词分为形容词性物主代词和名词性物主代词。让我们一起来看看它们的区别吧。
1. 构成
形容词性物主代词 第一人称 my我的 our我们的
第二人称 your 你的/你们的
第三人称 his他的 her 她的 its它的 their他们的/她们的/它们的
名词性物主代词 第一人称 mine我的 ours我们的
第二人称 yours 你的/你们的
第三人称 his他的 hers 她的 its它的 theirs他们的/她们的/它们的
2. 用法
（1）形容词性物主代词起形容词的作用，用在名词之前。
This is my mother. 这位是我妈妈。
Are these your crayons 这些是你（们）的蜡笔吗
（2）名词性物主代词起名词的作用，相当于“形容词性物主代词 + 名词”。
