名词性物主代词
1. 名词性物主代词在句子中独立使用，相当于“形容词性物主
代词+名词”，其后不能接名词。
2. 在物体已经指出的情况下，用来代替已知物体的物主代词。
The book is mine. 这本书是我的。
There is something wrong with my computer. Could I use yours
我的电脑出问题了。我可以用你的吗？
3. 名词性物主代词在句中可作主语、宾语、表语等。作主语
时，谓语动词的单复数形式由名词性物主代词所指代的名
词的数来决定。
My tennis shoes are right here. His are over there.
我的网球鞋就在这里，他的在那边。
