(完整版)小学Therebe句型的讲解和练习题

Therebe句型的用法：表示某个地方存在某物或某人，Be动词的单复数必须依主语的变化而变化。单数is复数are如：房间里有一张桌子。Thereisatableintheroom.树上有很多鸟。Therearesomebirdsonthetree.一、Therebe句型的结构：1.（一）Thereis+单数可数+地点状语例：Thereisaruleronthedesk.书桌上有一把尺。（二）Thereare+复数主语+地点状语例：Therearefourapplesonthetree.树上有四个苹果。Therearesomeflowersinthepark.公园里有许多花。（三）thereis+不可数名词+地点状语（即使有some也是单数）例：Thereissomewaterinthebottle.瓶子里有一些水。（水是不可数名词）2.Therebe选择就近原则：Therebe句型的就近原则是Therebe句型中语法项目的重点考点。Therebe句型中be动词的单复数形式由最挨近的一项的单复数决定。如：Thereisapen,twobooksandmanypencilsonthedesk.在本句中尽管有钢笔、书和铅笔，但是由于离be动词最近的一项是单数apen，因此，be动词用单数is。二、Therebe句型的疑问句及回答（一）Therebe句型的疑问1.在“Thereis/are...”的疑问句中,要把Be动词放在there之前,并将句号变问号。难点:句中出现的some要改成any。2.肯定回答为：Yes,thereis/are.3.否定回答为:No,thereisn’t/aren’t.例句可数名词单数1.肯定句Thereisanappleonthetree.疑问句Isthereanappleonthetree?肯定回答:Yes,thereis.否定回答:No,thereisn’t.可数名词复数2.肯定句Therearefivepensonthedesk.疑问句Aretherefivepensonthedesk?肯定回答:Yes,thereare.否定回答No,therearen’t.不可数名词的时候3.肯定句Thereissomewaterinthecup.（水是不可数名词）否定句Isthereanywaterinthecup?肯定回答:Yes,thereis.否定回答:No,thereisn’t.三、Therebe句型的否定形式（一）Therebe句型的否定：否定形式只要在be动词后面加not即可，isnot=isn’tarenot=aren’t但要注意的是句中如果出现some则改成any.1.Thereisaknifeinthekitchen.否定:Thereisnotaknifeinthekitchen.2.Therearefiveapplesonthetree.否定:Therearenotfiveapplesonthetree.3.Thereissomeinkinthebottle.否定:Thereisnotanyinkinthebottle.（ink是墨水，不可数名词）4.Therearesomebirdssinginginthetree.否定:Therearenotanybirdssinginginthetree.练习一、选择题1.Thereare_____pencilsinmypencilbox.A.aB.anC.some2.Thereis______rockingchairinmybedroom.A.aB.anC.five3.Thereare_____newbooksforyou.A.aB.anC.two4.Thereis_______ruleronthedesk.A.aB.anC.some5.Thereis________caponthedesk.A.OneB.anC.three6.Thereare______pencilboxesinthebookbag.A.aB.anC.two二.把下例句子改成疑问句:1.Therearefourapplesontheground.疑问句:_______________________________________2.Therearefivebirdsinthetree.疑问句:_______________________________________3.Therearefivebirdssinginginthetree.疑问句:_______________________________________4.Thereisanarmchairinthelivingroom.疑问句:______________________________________5.There’sasofainthelivingroom.疑问句:______________________________________6.There’saduckinthefarm.疑问句:______________________________________三.把下例句子改成否定句:1.Therearetwobowlsonthetable.否定句:__________________________________________2.Therearesomebeautifulflowersinthegarden.否定句:__________________________________________3.Thereisatreeinthegarden.否定句:___________________________________________4.Thereisanappletreeinthegarden.否定句:____________________________________________四、背诵下列Therebe句型1.Therearesomepencilsinmypencilbox.2.Thereisnoinkinmypen.3.Therearetwonewbooksforyou.4.Thereisoneruleronthedesk.5.Thereisonecaponthedesk.6.Therearetwopencilboxesinthebookbag.7.Therearefourapplesontheground.8.Therearefivebirdsinthetree.9.Therearefivebirdssinginginthetree.10.Thereisanarmchairinthelivingroom.11.There’sasofainthelivingroom.
