3）简略回答用____代替this/that，用_____代替these/those。
4）形容词性物主代词与名词性物主代词的不同：形容词性物主代词后需带名词，名词性物主代词后不能再接名词。

【知识构建】
表示所有关系的代词叫做物主代词
(Possessive
Pronouns)
,
也叫人称代词的所有格。物主代词分为形容词性物主代词和名词性物主代词两种。物主代词有人称和数的变化。

【巧学妙记】
形容词性物主代词与名词性物主代词的区别
物主代词分两家,
形容词性名词性。
形容词性能力差,
自己不能来当家。
句子当中作定语,
身后定把名词加。
物主代词名词性,
相当名词可单用。
his,
its无变化,
my和mine要牢记。
其余变形规律化,
形性后加s尾巴。
