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.itistheyareThoseare39Completethequestionsandanswersabouteachpicture.根据图片补全问句和答语。3aIs______yourbook?Yes,itis.No.it_______.Are_____mypencils?Yes,_____are.No,theyaren’t.Is______hisruler?Yes,it______.No,itisn’t.Are______herpens?Yes,theyare.No,they______.thisisn’tthesetheythatisthosearen’t40Readthequestionsandcompletetheanswers.Isthisherruler?IsthatEric’sschoolbag?Arethesehispencils?ArethoseAnna’sbooks?Yes,.It’s.No,.Sally’s.Yes,.They’re.No,.mine.itishersitisn’tItistheyarehistheyaren’tThey’re3bPutsomethingsintotheteacher’sbox.Thentakesomethingoutoftheboxandfindtheowner.Youonlyhavetwoguesses!Isthisyoureraser?No,itisn’t.3CSentences:1.—Isthisyourpencil?—Yes,itis.It’smine./No,itisn’t.It’shers.2.—IsthatEric’sschoolbag?—No,itisn’t.It’sSally’s.3.—ArethoseAnna’sbooks?—No,theyaren’t.Theyaremine.Grammar:1.be动词引导的一般疑问句及回答2.名词所有格Summary用括号中所给单词的适当形式填空1.—Isthis_________ruler?—No,it’s________(she).It’snot________(I).2.Myfatherandmotherareteachers.________(them)areverybusy(忙的).3.—Arethese_________(you)pencils?—No,theyaren’t.They’re_________(he).4.Theeraserisnot________(you).It’s________(I).5.—Whoisit?—It’s________(I)brother.yourhersmineTheyyourhisyoursminemyPractice1.这是我的字典。
