名詞性物主代詞形容詞性物主代詞

名詞性物主代詞第一人稱my（我的）mine（我的所有物）第二人稱your（你的）yours（你的所有物）第三人稱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）形容詞性物主代詞myyourhisher形容詞性物主代詞起形容詞的作用，后面加名詞Eg.mybookyourpencilhisschoolbag herruler名詞性物主代詞。mine，his,hers，yours

等是名詞性物主代詞，相當于一個名詞，可以在句子中單獨使用。它相當于“形容詞物主代詞+名詞”。而形容詞性物主代詞只能和名詞在一起使用。名詞性物主代詞mine(=my+名詞)yours(=your+名詞）his(=his+名詞)hers(=her+名詞)名詞性物主代詞=形容詞性物主代詞+名詞為了避免重復,后面就不再加東西了Isthisyourpen?No,itisn't.It'sherpen.(為了避免重復)No,itisn’t.It’shers.(hers=herpen)Isthisherpencil?No,itisn’t.It’smypencil.(為了避免重復)No,itisn’t.It’smine.(mine=mypencil)Isthishereaser?Yes,it’shereraser.(為了避免重復)Yes,it’shers.hers=hereraserIsthatyourschoolbag?No,itisn’t.It’shisschoolbag.(為了避免重復)No,itisn’t.It’shis.his=hisschoolbag注意：在使用名詞性物主代詞時，必須有特定的語言環(huán)境，也就是要省略的名詞大家已經(jīng)知道，已經(jīng)提起過。例：It‘shers.是她的。

（單獨使用大家不知是怎么回事，不可以這樣用）

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

Lost閱讀指導：1.在2b中有四條信息，每條信息中都有一件物品。細讀信息找到物品。2.在第一條信息中，開頭是LinHai，結(jié)尾是Mike，由常識可知是Mike給LinHai的留言條，由關(guān)鍵句“Isityours?它是你的嗎？”，可知是Mike拾到的該物。故此條是Found條。3.由第二條信息中的第一句話“Isthisyourwatch?”，可知是John撿到的手表。故此條也是Found條。4.第三條和第四信息中明確有Found和Lost的說明，故較容易確定。

本題是寫尋物啟事和失物招領。1.應通讀全文，明白大意，確定是失物招領，還是尋物啟示。在第一則信息中，由關(guān)鍵詞mynotebook，及下文的“請打電話679-8871給我”，可知這是一則尋物啟示；在第二則信息中，由關(guān)鍵詞Arethese…?這些是你的嗎？可推測這是一則失物招領。2.弄清選項中各項的意思，根據(jù)信息中的內(nèi)容，逐空對號入座。
