知识梳理
1. 形容词性物主代词的用法
（1）形容词性物主代词具有形容词的特性，常放在名词前面作定语，表明
该名词所表示的人或物是“谁的”。如：
My friend, Toby, is an English boy. 我的朋友托比是个英国男孩。
（2）与形容词一起修饰名词时，形容词性物主代词要放在形容词的前面。如：
His old bike is lost. 他的旧自行车丢了。
注意：如果名词前已经用了形容词性物主代词，就不能再用冠词（a, an, the）
或指示代词（this, that, these, those）等修饰词。
2. 名词性物主代词的用法
（1）名词性物主代词在句子中可以作主语、宾语、表语等。
1）作主语。如：
May I borrow your bike Yours works better.
我可以借用你的自行车吗？你的比我的好骑。
2）作宾语。如：
I don’t like my camera. I like yours.
我不喜欢我的照相机，我喜欢你的。
3）作表语。如：
That computer isn’t mine, it’s yours.
那台电脑不是我的，是你的。
（2）名词性物主代词有时可以和of构成短语。如：
A friend of mine is a good tour guide.
我的一个朋友是一位很好的导游。
（3）名词性物主代词作主语时，谓语动词的单、复
数形式取决于它所替代的名词的数。如：
①My hair is long, hers is short.
我的头发长，她的头发短。
②Your mobile phones are new, ours are old.
你们的手机新，我们的旧。

单数 第一人称 I me my mine
第二人称 you you your yours
第三人称 he she it him her it his her its his

复数 第一人称 we us our ours
第二人称 you you your yours
第三人称 they them their theirs
物主代词两类型，形容词与名词性。
形容词性作定语，后面定把名词用。
名词性要独立用，主宾表语它都充。
助记：物主代词用法口诀
1. 大部分形容词性物主代词在后面加 “s”构成名词
性物主代词.有3个特殊情况:
my—mine, his— his, its—its。
2. 形容词性物主代词与名词性物主代词的区别：
前者有名词的含义，后面需跟名词；后者可单独使用，相当于对应的形容词性物主代词加名词。
3. 名词性物主代词作主语时，如果含义是单数，后面的be动词用is；如果含义是复数，那么be动词用are。
