therebe结构教学设计

Therebe结构教学目标：1．学习Therebe结构的定义。2．理解掌握Therebe的各种结构：肯定式、否定式、一般疑问句及肯否定回答的知识框架。教学重难点：Therebe的否定式、疑问句中，当句子中有“some”的时候，需把“some”变为“any”。教学用具：实物各种水果、学习用具、卡片、杯子等教学流程：一、课前导入.1、师生日常会话，谈自己的教室内的物品布置,让学生用Therebe句型描述教室有什么物品。T:Hello,children.What’sinourclassroom?S1:Thereis/are…2、教师揭示引出Therebe结构的定义。Therebe结构又称存在句，表示某地存在某物。如：Thereisabookonthedesk.Therearefourdesksintheclassroom.二、教授新课。步骤1：教师拿出水果描述，引出Therebe结构的肯定式。、教师展示水果。T：Doyoulikefruits?S:Yes,Ido.T:Whatdoyoulikefruits?S:Ilike.....T：What’sthis?/these?S:It’sapear./pears.T:Howmanypearsarethereonthedesk?S:Thereis/are..Onthedesk.看例句：Thereisapenonthedesk.Thereissomewaterinthecup.Therearetwopensonthedesk师生互动练习,找规律：（注意some用在肯定句中）Thereisacomputeronthedesk.Thereissomebreadontheplate.Therearetwoboysunderthetree.结构：Thereis+单数或不可数名词+某地Thereare+可数名词的复数形式+某地.表示：在某地有某物或某人。小结Therebe结构的肯定式：板书：Therebe(is/are)+名词（单数/复数）+地点状语。2.就近原则：(1)看例句Thereisapenandtwobooksonthedesk.Therearetwobooksandapenonthedesk.(2)找规律在therebe句型中，如有几件物品，be动词的选择取决于最靠近它的那个名词，我们常称之为“就近原则”。Thereisacomputerandtwocupsonthedesk.Therearetwocupsandacomputeronthedesk.步骤2：教师拿出学习用具描述，引出Therebe结构的否定式。、教师展示文具。T:Ihavemanypencilsinmyhand.WhocanCountit?S:one、two.......T:Howmanypencilsarethereinmyhand.S:Thereare......inyourhand.T:Howmanypensarethereinmyhand?(此时教师并非手中拿钢笔）S：No......教师让学生两人一组，拿出文具进行对话练习。（注意any用在否定句中）Thereisnotaduckintheriver.小结Therebe结构的否定式：therebe句型的否定句在be动词后加not,板书：Therebe(is/are)+not+名词（单数/复数）+地点状语。步骤3：教师拿杯子（分有水还是无水）描述，引出Therebe结构的一般疑问句及肯否定回答。、教师拿出两个杯子中的水进行描述。T：Everyone，Lookatmycup.Therearesomewaterinthecup.Butthisone.(指名学生说另一个空杯子）S：There......T：Isthereanymilkintheglass?S:Yes,Thereis/Thereisn’t.T:Therearesomewaterinthecup.S:Arethereanywaterinthecup?T:Yes.Thereare/Therearen’t师生互动练习。（注意any用一般疑问句中）小结Therebe结构的疑问式。板书：Be(is/are)+there+名词（单数/复数）+地点状语。步骤4：教师以班级男生和女生的数量，引出Therebe结构的特殊疑问句形式。、教师分别叫一名男生和女生对本班学生进行数一数。S1：Boys.......S2:girls.......师生互动练习。小结Therebe结构的特殊疑问句。针对数量提问的特殊疑问句的基本结构是：Howmany+名词复数+arethere+介词短语？Howmuch+不可数名词+isthere+介词短语？特殊疑问词+be(is/are)+there+地点状语。三、巩固练习。1、把下列句子变成否定句、疑问句及做肯否定回答。Thereisahouseonthefarm。Therearesomechairsintheclassroom.2、看图说句子。四、课后思考。HomeworkTherebe句型与have的区别五、小结。六、板书设计。Therebe结构肯定式Therebe(is/are)+名词（单数/复数）+地点状语。否定式Therebe(is/are)+not+名词（单数/复数）+地点状语。Therebe结构疑问式Be(is/are)+there+名词（单数/复数）+地点状语。特殊疑问式特殊疑问词+名词（单数/复数）+be(is/are)+there+地点状语。课内练习一、用is或are填空1.There________manymonkeysinthemountain.2There_______abeautifulgardeninourschool.3.There_________somewaterintheglass.4.There__________somebreadonthetable.5.There__________abirdinthetree.6.There__________sometreesandacarnearthehouse.二、单项选择()1.There＿＿somemilk,someeggsandafewapplesonthetable.A.isB.areC.hasD.have()2.There____anappleandtenbananasinthebasket.A.areB.isC.hasD.have()3.There___not____milkinthecuponthetable.A.are,anyB.are,muchC.is,anyD.is,much()4.Arethere___studentsintheroom?A.someB.anyC.manyD.much()5.Howmanyboys____thereinClassone?A.beB.isC.areD.Am三、将下列句子变成否定句和疑问句。1.Therearemanyapplesinthebox.2.Therearesomeapplesinthetree。3.Thereisahouseonthefarm.4.Therearesomegoatsonthefarm.5.Thereissomebreadandeggsontheplate.
