形容词性物主代词起形容词的作用，用在名词前。
例：
1. This is my book. 这是我的书。
2. We love our motherland.
我们热爱我们的祖国。 形容词性物主代词
2. 名词性物主代词起名词的作用。
例：
Look at the two pencils. The red one is yours
and the blue one is mine.
看那两支铅笔，红的是你的，蓝的是我的。
2.Lucy’s hair is longer than Lily's.
露西的头发比莉莉的更长。
3. 注意：在使用名词性物主代词时，必须有特定的语言环境，也就是要省略的名词大家已经知道，已经提起过。
例： It's hers. 是她的。
单独使用大家不知是怎么回事，不可以这样用。
There is a book. It's hers. 这有本书。是她的（书）。
（这里的hers=her book）
只有上文提及了某个名词，才会知道名词性物主代词指代的事物。
4. 名词性物主代词=形容词性物主代词+名词 为避免重复使用名词，有时可用“名词性物主代词”来代替“形容词性物主代词+名词”的形式。
例：My bag is yellow, her bag is red, his bag is blue and your bag is pink.
为避免重复使用bag，可写成My bag（形容词性） is yellow, hers（名词性=her bag） is red, his（名词性=his bag） is blue and yours（名词性=your bag） is pink.Do exercisesI. 根据句意及首字母提示，补全句中所缺单词。
