Its not mine.)这是你的尺子，它不是我的。Those arent his books. Theyre her books. (= Those books arent his. Theyre hers. ) 那些书不是他的。它们是她的。,18,名词性物主代词,mine (mine=my +名词)yours (yours=your+名词）his (his=his+名词)hers (hers=her+名词)名词性物主代词=形容词性物主代词+名词(为了避免重复) (后面就不再加东西了),19,Is this your pen?No, it isnt. Its her pen.(为了避免重复)No, it isnt. Its hers.(hers=her pen),20,Is this her pencil?No, it isnt. Its my pencil.(为了避免重复)No, it isnt. Its mine.(mine=my pencil),21,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：Its 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.
