6.【代词】形容词性物主代词&名词性物主代词
【原文链接】—Are they yours? 它们是你的吗？—No, they aren’t. 不，它们不是。
【总结】
表示所有关系的代词叫做物主代词，也可叫做代词所有格。物主代词分形容性物主代词和名词性物主代词
二种，物主代词也有人称和数的变化，见下表：
形容词性物主代词(my/your/his/her/its/our/their)+名词，表示是属于谁的东西。 如：I love my country
.
而名词性物主代词(mine/yours/his/hers/its/ours/theirs 则相单于对应的形容词性物主代词+名词,故其后不必加名词。
如： —Is this your book? 这是你的书吗？
—No, it isn’t , it’s hers . = it’s her book . 不。这是她的书。
注意：形容词性物主代词+名词= 名词性物主代词
This is her book. = This book is hers. 如： —Whose pen is it? 这是谁的钢笔？ —It ’s mine. 是我的
