小組內(nèi)討論一般疑問句的構(gòu)成。S1:Excuseme.Isthisyourbook,LiYang？S2:Yes,itis.Thankyou.S1:Andisthatyourdictionary？S2:No,itisn’t.It’sherdictionary.S1:Aretheseyourbooks?S2:Yes,theyare.通過以上活動(dòng)，我們可以知道，指示代詞做主語的一般疑問句的構(gòu)成如下：1.______+this/that+2._____________？肯定回答：3.___________.否定回答：4._____________.5._______+these/those+6.________________？肯定回答：7.__________________.否定回答：8.__________________.Is名詞單數(shù)Yes,itis.No,itisn’t.Are名詞復(fù)數(shù)Yes,theyare.No,theyaren’t.活動(dòng)小結(jié)探究二名詞性物主代詞和形容詞性物主代詞Isthisyourschoolbag?Yes,itis.It'smine.1.Isthisherruler?

通過以上活動(dòng)，我們可以知道：名詞性物主代詞=1.__________________+2.______，為避免重復(fù)使用名詞，有時(shí)可用3._______________來代替“形容詞性物主代詞+名詞”。形容詞性物主代詞名詞名詞性物主代詞活動(dòng)小結(jié)當(dāng)堂檢測(cè)根據(jù)句子意思，選詞填空。1．_____(This/That)isabook._____(This/That)isapenoverthere.2．—Isthatyourschoolbag?—____(No/Not)，itisn't.It's____(she/her)schoolbag.3．—Arethese____(yours/his)pencils?—Yes，they're______(mine/his)．4．—Isthis____(her/hers)picture?—No，it_____(is/isn't)．5．—Are______(that/those)yourmaps?—Yes，theyare______(me/mine)．ThisThatNoherhismineherisn'tthosemineUnit3SectionA(GrammarFocus~3c)指示代詞做主語的一般疑問句：①Is+this/that+名詞單數(shù)？肯定回答：Yes,itis.否定回答：No,itisn’t.②Are+these/those+名詞復(fù)數(shù)？肯定回答：Yes,theyare.否定回答：No,theyaren’t.重點(diǎn)句式：—Isthisherruler？—Yes
