名词性物主代词形容词性物主代词

名词性物主代词第一人称my（我的）mine（我的所有物）第二人称your（你的）yours（你的所有物）第三人称his（他的）his（他的所有物）her（她的）hers（她的所有物）its（它的）its（它的所有物）形容词性物主代词myyourhisher形容词性物主代词起形容词的作用，后面加名词Eg.mybookyourpencilhisschoolbag herruler名词性物主代词。mine，his,hers，yours

等是名词性物主代词，相当于一个名词，可以在句子中单独使用。它相当于“形容词物主代词+名词”。而形容词性物主代词只能和名词在一起使用。名词性物主代词mine(=my+名词)yours(=your+名词）his(=his+名词)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Isthisyourpen?No,itisn't.It'sherpen.(为了避免重复)No,itisn’t.It’shers.(hers=herpen)Isthisherpencil?No,itisn’t.It’smypencil.(为了避免重复)No,itisn’t.It’smine.(mine=mypencil)Isthishereaser?Yes,it’shereraser.(为了避免重复)Yes,it’shers.hers=hereraserIsthatyourschoolbag?No,itisn’t.It’shisschoolbag.(为了避免重复)No,itisn’t.It’shis.his=hisschoolbag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‘shers.是她的。

（单独使用大家不知是怎么回事，不可以这样用）

Thereisabook.It'shers.那有本书。是她的。（先提及，大家才明白）

Lost阅读指导：1.在2b中有四条信息，每条信息中都有一件物品。细读信息找到物品。2.在第一条信息中，开头是LinHai，结尾是Mike，由常识可知是Mike给LinHai的留言条，由关键句“Isityours?它是你的吗？”，可知是Mike拾到的该物。故此条是Found条。3.由第二条信息中的第一句话“Isthisyourwatch?”，可知是John捡到的手表。故此条也是Found条。4.第三条和第四信息中明确有Found和Lost的说明，故较容易确定。
