一、物主代词物主代词是表示某物属于“谁的”的代词，分为形容词性物主代词和名词性物主代词两种。形容词性物主代词相当于形容词，置于名词之前做定语。如：hername,yourbirthday,theirfriends。名词性物主代词相当于名词，不能用于名词前。见下表：类别形容词性物主代词名词性物主代词汉语意思单数形式mymine我的youryours你的hishis他的herhers她的itsits它的复数形式ourours我们的youryours你们的theirtheirs他们的形容词性物主代词起形容词作用，在句中只能作定语,也就是说它后面必须跟一个名词。即：形容词性物主代词＋名词。形容词性物主代词前面不能加冠词a/an/the。Thisismybike.这是我的自行车。Hername’sMary.她的名字是玛丽。形容词性物主代词mine,yours,hers,his等是名词性物主代词，相当于“形容词性物主代词my/your/her/his＋名词”。名词性物主代词的用法：(1)名词性物主代词＝形容词性物主代词＋名词(2)名词性物主代词在句中作主语、宾语或表语。

名词性物主代词1.Hispenisgreen.Mineisblue.(作主语)

他的钢笔是绿色的，我的(钢笔)是蓝色的。2.Myeraserisinthepencilbox.Whatabout

yours？(作宾语)我的橡皮在铅笔盒里，你的呢？（=Hispenisgreen,mypenisblue.)(=Myeraserisinthepencilbox,whataboutyoureraser?)3.Thisismyruler,thatoneishers.(作表语)这是我的直尺，那把是她的。(=Thisismyruler,thatoneisherruler.)[口诀]物主代词分形、名，形式、用法各不同；形容词性先出场，我的my你的your；男的his女的her，它的its不加撇；我们的our他们的their，别忘记！物主代词形变名，多数词尾加“s”；my变mine须分明，his和its是本身；形跟名词，名不跟，用法牢记不会错！

口诀

有“名”则“形“，无“名”则“名”

意思是：后面是名词的话，前面就要用形容词性物主代词。后面没有名词的话，就用名词性物主代词。物主代词的注意事项练一练，填一填Thisismybook.

2．结构：Be(Am/Is/Are)＋主语＋其他？3．回答：肯定回答：Yes,主语＋be(am/is/are).否定回答：No,主语＋be(am/is/are)＋not.Isthatyourbike?↗那是你的自行车吗？Aretheyyourfriends?↗

他们是你的朋友吗？其答语：肯定回答：Yes,主语+be(am,is,are)否定回答：No,主语+be(am,is,are)not--Isthisyourpencil?↗这是你的铅笔吗？ --Yes,itis./No,itisn’t.↘是的。/不是。※no和not二者都是“不”的意思,用法不同。no:可单独使用，用于回答一般疑问句，反义词为yes；not:不能单独使用，要和be动词、助动词等一起构成否定句。

---Isthisyourpencil?这是你的铅笔吗?---No,itisn’t.不,不是。

Itisnotmybook.这不是我的书。Thisismypencil.Isthisyourpencil?4.含有be动词的陈述句变为一般疑问句的步骤

一调二改三问号：将句中动词be(am,is,are)提到主语前，并大写开头字母，主语第一人称变第二人称（二、三人称不变），句末用问号，即变成了一般疑问句。5．注意：(1)当一般疑问句的主语不是人称代词时，回答时用相对应的人称代词来替换该主语。—IsLucyyoursister?露西是你的姐姐吗？—No,sheisn't.不，她不是。

(2)在对一般疑问句作肯定回答时，主语不能与be动词缩写为一个词。—IsLindaagirl?琳达是一个女孩吗？—Yes,sheis.是的，她是。(3)对this,that提问时，无论指人还是物，其回答一律用it。—Isthisapencil?这是一支铅笔吗？

—Yes,itis.是的，它是。—Isthatyoursister?那是你的姐姐吗？—No,itisn't.不，不是。(4)对these,those提问时，其回答用they。—Arethosehisbooks?那些是他的书吗？—Yes,theyare.是的，它们是。语法精练Ⅰ.用括号内所给单词的适当形式填空1．Thatpenispurple.Itisnot________pen.________isorange.(I)2．—Isthis________(you)watch?—No.It'snot________(I)．It's________(he)．3．Thesemapsare________(she)．myMineyourminehishers4．________penisnothere.________isathome(在家)．(he)5．—Arethese________(she)books?—No,theyaren't.HisHisherⅡ.按要求完成下列各题，每空一词1．Thisisherruler.(改为一般疑问句)________________herruler?2．Isthatyourbook？(作否定回答)No,________________．Isthisitisn't3．Isthisyourmother？(作肯定回答)Yes,________________．4．Aretheseyourpencils？(作肯定回答)Yes,________________．5．Arethosehismaps？(改为陈述句)________________hismaps.itistheyareThoseare3aCompletethequestionsandanswersabouteachpicture.thisisn’tthesetheythatisthosearen’t武汉启智文化传媒1.Isthisherruler?2.Isthatherruler?3.Arethesehispencils?4.ArethoseAnna’sbooks?Yes,_______.They’re___.No,______.___Sally’s.No,__________.________mine.Yes,____.It’s_____.Readthequestionsandcompletetheanswers.itis3bhersitisn’tIt’stheyarehistheyaren’tThey’re3cPutsomethingsintotheteacher’sbox.Thentakeonethingoutoftheboxandfindtheowner.Youonlyhavetwoguesses!Isthisyoureraser?No,itisn’t.Findtheowneroftheeraser.A:
