七年级英语There---be句型讲解和练习

诚信专业优质规范第1页句型一、专题讲解Therebe句型1、定义：Therebe结构主要用以表达“某地有某人(某物)”。其基本句型为“Therebe+某物或某人(主语)+某地”。2、be动词的选择：Therebe结构中的谓语动词be（is/are）在人称和数上应与其后的主语保持一致。主语是不可数名词或单数可数名词时用is；主语是复数时用are。3、具体结构：(1)Thereis+单数可数名词/不可数名词+地点状语.E.g.Thereisadeskintheclassroom.在教室里有一张桌子。(2)Thereare+复数名词+地点状语.E.g.Thereare5applesinthebox.盒子里有五个苹果。口诀：“有”字放前面，有“啥”放中间；时间地点放后面；单数is,复数are注意be的两变化。4、句型变化：(1)、否定句：therebe的否定式通常在be后加not。E.g.Thereisabikeunderthetree.树下有一辆自行车。Thereisn'tabikeunderthetree.E.g.Thereare2littlegirlsintheroom.在房间里有两个小女孩。Therearen't2littlegirlsintheroom.(2)、一般疑问句及其答语：1、一般疑问句：把be动词提前,首字母大写,句末用问号即可。2、回答时，“用什么问，就用什么答”，用Is/Arethere来提问，就用thereis/are来回答。肯定回答：Yes,thereis/are.否定回答：No,thereisn't/aren't.E.g.1、Therearetwocatsinthetree.树上有两只猫。Aretheretwocatsinthetree?Yes,thereare.No,therearen't..2、Thereisacomputeronthedesk.在桌子上有一台电脑。Isthereacomputeronthedesk？Yes,thereis.No,thereisn't.课堂练习：1.Thereisanewbedandanolddeskintheroom.否定句一般疑问句否定回答5、some和any在“therebe”句型中的用法：some一些（some用于肯定句）any一些（any用于否定句和一般疑问句）注意：Therebe句型在变成否定句或一般疑问句时，要注意把句中的some变成any。第2页E.g.1、Thereissomewaterinthebottle.在瓶子里有一些水。Thereisn'tanywaterinthebottle.（否定句）Isthereanywaterinthebottle？（一般疑问句）2、Therearesomechildreninthepicture.图片里有一些小孩。Therearen'tanychildreninthepicture.（否定句）Arethereanychildreninthepicture？（一般疑问句）课堂练习：1.--Arethere_____shopsnearhere?--No,thereare_____shopsnearhere.A.some,notB.some,anyC.any,notD.any,no2．Therearesometablesonthefloor.（变为否定句）6、就近原则：there是个近视眼。若句子中有几个并列的主语时,be的形式要与离其最近的一个主语在人称和数上保持一致。E.g.1.Thereisapen,twopencilsandsomebooksonthedesk.书桌上有一支钢笔、两支铅笔和一些书。2.Therearetwopencils,apenandsomebooksonthedesk.书桌上有两支铅笔、一支钢笔和一些书。3.Theresomebooks，twopencilsandapenonthedesk.书桌上有一些书、两支铅笔和一支钢笔。课堂练习：Theremilkandeggsonthetable.在桌子上有牛奶和鸡蛋。Thereeggsandmilkonthetable.7、“therebe”和“have”的区别Therebe表示“存在有”；have（has）表示“所属有”。他们都翻译为“有”，但具体用法不相同，且两种结构不能同时合用。E.g.1、Ihaveabook.我有一本书。（注：书归我所有，我是书的主人。→所属有）2、Thereisabookonthedesk.在桌子上有一本书。（注：书只是存在于桌子上，但书不属于桌子所有。→存在有）8、常见的的介词和介词短语：介词：at在.....in在......里面on在......上面under在......下面behind在......后面near在......附近介词短语举例：athome在家inthebox在盒子onthefloor在地板上underthetree在树下behindthedoor在门后面nearthezoo在动物园附近infrontof在……前面（2）变式练习一、用恰当的be动词填空。1.There_____amaponthewall.2.There_____manythingsonherdesk.3.There_____abigdogandasmallcatnearthetable.4.There_____twobikesunderthetree.5.There_____apen,twopencilsandaneraserinthepencil-box.6.There_____somebooks,apencil-boxandapenonherdesk.7.Theresomemilkintheglass.8.Theresomepeopleunderthebigtree.第3页9.Therelotsofflowersinourgarden.二、单选题1.______therearadioonyourdesk?A.AreB.IsC.Am2.____thereamaponthewall?Yes,there______.A.Are/isB.Is/areC.Is/isD.Are/are3.There___twoapples,oneorangeandonebananaonthetable.A.hasB.areC.amD.is4.There_____apencil,abookandtwopensonthetable.A.isB.areC.amD.have5.Arethere_____picturesonthewall?No,therearen't____.A.any/anyB.some/anyC.some/someD.any/some6.There_______somewaterinthecup.A.isB.amC.areD.be二、巩固练习一、用have或has填空。1．I_______anicepicture.2．He_______agoodfriend.3．They______somekites.4．We_______someflowers.5．Hermother_______avase(花瓶).6．Nancy______manyskirts.7．Myfriends_______afootball.8．Whatdoyou______?9．Whatdoyourfriends______?10．Hisbrother______abasketball.1.把下列句子改为否定句和一般疑问句。1．Ihaveaping-pongball.否疑2．Thereisabookandapeninthebag.否疑3．HisaunthasanewTV.否疑4．Therearesomeboysinourclass.否疑五、拓展训练一、单选题1.There_______somewaterinthecup.A.isB.amC.areD.be2.______thereabookonthedesknow?A.IsB.AreC.WereD.Was3.Howmanypeople______inyourfamily?A.doyouhaveB.arethereC.youhadD.thereare4.There______anytreesinfrontoftheclassroom.A.isn'tB.aren'tC.hasn'tD.haven't5.There______sheepinthefield.A.isB.aremuchC.aremanyD.area第4页6.Thereare______inthefield.Theyareeatinggrass.A.ahorseB.muchhorsesC.manyhorseD.manyhorses7.There______anewbedandanolddeskintheroom.A.isB.areC.haveD.has8.______anytreesinthepicture?A.IsthereB.ArethereC.WasthereD.Werethere9.There____pencil-box,twobooksandsomeflowersonthedesk.A.isaB.aresomeC.hasaD.havesome10.Howmany____arethereinyourclassroom?A.desksB.deskC.chairD.door二、用“have,has”，“thereis，thereare”或者“isthere，arethere”填空。1.I______agoodfatherandagoodmother.2.___________abookonthedesk.3.He________atape-recorder.4.They_________anicegarden.5.Whatdoyou________?6._____________areading-roominthebuilding?7.WhatdoesMike________?8._____________anybooksinthebag?9.Myfather_______astory-book.10.______________anyflowersinthegarden?11.Howmanystudents____________intheclassroom?12.Myparents_________somenicepictures.13.____________somemapsonthewall.14.David’sfriends_________somedogs.15._____________manychildrenonthehill.家庭作业一、填上恰当的be动词1.There____twowomeninthekitchen.2.There____anorangeinthebasket.3.There____threepensonthetable.4.____thereanybirdsinthetree?5.There____somegirlsplayinginthepark.6.There____manyanimalsinthezoo.7.There____twentyapplesonthetree.8.There____fourseasonsinayear.二、按要求完成句子1.Thereisacomputerinmyhouse.(一般疑问句)___________acomputerin______house?2.Therearesomeflowersontheteachers’desk.(一般疑问句)__________________flowersontheteachers’desk?3.Therearen’tanyapplesonthetree.(变回肯定句）There___________
