教学课件英语七年级上册人教版Unit5Doyouhaveasoccerball?SectionA2a—3cGrammarFocus1.Doyouhaveaping-pongball?这是一个现在时行为动词(do)的一般疑问句,其中have是实义动词,表示“某人拥有”。句中do为助动词,没有实际意义。只是帮助构成句式。Doyouhaveawatch?你有手表吗？主语have是英语中很有用的动词，基本含义是“有”。如课文中的Ihaveasoccerball.have在he,she,it后面要变成has。ExplanationExplanation即：一般现在时态第三人称单数形式。如:Hehasabasketball.Have当动词“有”的意思时,句式是：陈述句：Ihaveanicebag.疑问句：Doyouhaveanicebag?Yes,Ido.No,Idon’t.否定句：Idon’thaveanicebag.have与其它的词组合成词组、短语，就不表示“有”了，其意思与后面的名词接近。如：haveclasses(上课);havebreakfast(吃早饭);haveagoodtime(玩得高兴);havesports(进行体育活动);haveadayoff(休假)等等。Explanation2.have与therebe句型的区别:Therebe是表示“在某处存在某物”;而have则是表示所属的意思，即“拥有”，通常是人。我们来看两个句子：Thereisabookonthedesk.书桌上有一本书。Ihavemanybooks.我有很多本书。3.Yes,Ido.这是个肯定的简略回答形式。其中do为动词,用来避免动词的重复。4.No.Idon’t.这是个否定的简略回答形式,其中don’t是do和not的缩写形式。Explanation5.Yes,he/shedoes.这是个肯定的简略回答形式。主语是第三人称代词，所以动词用does(does为do的第三人称单数形式）。6.No.he/shedoesn’t.这是个否定的简略回答形式,其中doesn’t是does和not的缩写形式。ExplanationPracticeDoyouhaveatennisracket?Yes,Ido.Whereisthetennisracket?It’sunderthesofa.PracticeDoesTomhaveabasketball?Yes,hedoes.Isthebasketballunderhisbed?No,itisn’t.PracticeDoesMaryhaveavolleyball?Yes,shedoes.Isthevolleyballunderherbed?Yes,itis.PracticeDotheyhaveaTV?Yes,theydo.IstheTVonthetable?Yes,itis.写出下列表达方式的缩写形式。1.donot=______2.doesnot=_______3.weare=______4.letus=_____don’tdoesn’twe’relet’s☆教材解读☆助动词do/does的用法◆do和does是助动词,帮助实义动词构成疑问句、否定句和简略回答。Dotheycome?他们来吗?Idon’tknow.我不知道。◆do与第一人称单、复数,第二人称复数和第三人称复数连用,does与第三人称单数连用。即:I,we,you,they等作主语的句子中用do;he,she,it等作主语的句子中用does。DoI/you/theyhave…?Doeshe/shehave…?【拓展】don’t=donot,doesn’t=doesnot,表示否定,意思是“不”。IhetheyyouwesheitEricWriteeachwordinthecorrectplaceinthechart.dodoesIhetheyyouwesheitEric3a1.A:_____youhaveabaseball?B:Yes,I____.A:Great!Ihaveabat.Let’splay！Fillintheblankswithdoordoes.Thenpracticetheconversationswithyourpartner.Dodo第一(I)、二(you)人称用do3b3.A:____yourfriendshaveabasketball?B:Yes,they____.Theyhavetwobasketballs.A:Well,let’splaybasketball.B:Thatsoundsgood.Dodo第三人称复数(yourfriends,they)用do。2.A:_____Johnhaveasoccerball?B:No,he________.A:_____hehaveaping-pongbat?B:Yes,he______.Ithinkhehasaping-pongball,too.A:Hmm…let’sask.Doesdoesn’tDoesdoes第三人称单数(John,he)用does☆教材解读☆1.Ithinkhehasaping-pongball,too.Ithink…表示“我想……;我认为……”,用来表达自己的判断或想法,可放在自己观点的前面或后面。Ithinkhe’syourbrother.我以为他是你的弟弟。Youcanplaysoccer,Ithink.我想,你会踢足球。2.Thatsoundsgood.那听起来不错。sound表示“听上去……;听起来……;听着……”。Thatsoundsinteresting.那听起来蛮有趣的。RememberthethingsinBob’sroom.Thencloseyourbooksandaskandanswerquestionswithapartner.A:Doeshehaveasoccerball?B:Yes,hedoes./No,hedoesn’t.3cvolleyballbasketballbaseballbatbaseballerasertapeplayerjackethatpicturedictionaryExercise用do,does,don’t或doesn’t填空1.—youhaveatennisracket?—No,I,butmybrother.2.—yoursisterhaveaping-pongball?—No,she.Shehasaping-pongbat.3.—theyhaveabasketball?—Sorry,Iknow.4.Theywanttoplaysoccer.Buttheyhaveasoccerball.5.—hewanttoplayvolleyball?—Yes,he.Dodon’tdoesDoesdoesn’tDodon’tdon’tDoesdoes1.Readandwritetheconversationsin3b.
