小升初英语基本语法与练习七Therebe结构知识要点1)英语中的Therebe结构意思是“有”,表示在某地或某时有某人或某物。Therebe结构强调的是“存在关系”。Therebe结构中的be具有时态变化(is,are,was,were).Therebe后接的如果是单数可数名词或不可数名词时,be只能是单数形式is或was;如:Thereisabookonthedesk.Therewassomemilkinthebottleyesterday.如:Therebe后接的如果是复数可数名词时,一定要用复数形式are或were。Therearesomebooksonthedesk.Thereweresomebooksonthedeskyesterday.2)在英语中表示“有”这一概念除了therebe结构以外,还有have/has。它们的用法区别:have/has表示“某物归某人所有”,强调所属关系,而therebe指“在某地或某时有某人或某物”,强调存在关系。比较:Thereisabusinourschool.(只表示存在,bus不一定属于学校)Ourschoolhasabus.(表示我们学校拥有bus这一财产).考查therebe句型的常见题型有单项填空、完型填空、句型转换和改错等。做这类题时,必须首先认真理解全句的意思,看是表示“存在”的“有”还是“拥有”来决定是否用therebe还是用其他句型。3)Therebe可以有现在时(thereis/are)、过去时(therewas/were)、将来时(thereis/aregoingtobe或therewillbe)和完成时(therehave/hasbeen);还可用theremustbe,therecan‘tbe,thereusedtobe等4)反意疑问句的构成:be(not)there?5)主谓一致:Therebe结构中的be动词要和后面所跟名词保持一致,遵循就近原则。注意:1.句型中含有some时,变为否定句、疑问句时一般要改为any。2.对数量提问:Howmany+可数名词复数+arethere+…?Howmuch+不可数名词+isthere+…?3.对句中sth.部分提问一般用What’s+地点状语?有时也用What‘sthere+地点状语?4.therebe句型中有时不用动词be,而用come,live,stand,lie,seemtobe,happentobe,等练习:I.将下列句子改成否定句和一般疑问句,并作肯定与否定回答。1.Thereissomejuiceinthefridge.______________________________________________________2.Thereweretwoappletreesinfrontofthehousetwoyearsago.______________________________________________________II..用therebe或have的适当形式填空。1.________anypencilsinyourpencil-box?2.________you_____________anypencilsinyourpencil-box?3.Lucy___________atwinsister,Lily.4._________aTVinourclassroomlastterm.5.Howmanyhours___________inaday?6.-Howmanylegs______atable________?-It_______four.7.-What’sinyourbedroom?-__________________abed,adeskandsomechairs.8..Myparents_____twochildrenand________fourpeopleinmyfamily.III.单项填空。()1.There___anyriceinthebowl.A.areB.isC.isn‘tD.aren’t()2.There___manyapplesonthetreelastyear.A.havebeenB.wereC.areD.is()3.Howmany___arethereintheroom?A.appleB.studentsC.milkD.paper()4.Doyouknowif___ameetingnextSunday?A.therewasgoingtohaveB.therewasgoingtobeC.istheregoingtobeD.therewillbe()5.Thereissomemilkinthebottle,____?A.isn‘tthereB.aren’tthereC.isn‘titD.arethere()6.There____alotofgoodnewsintoday’snewspaper.A.isB.areC.wasD.were()7.There____pencil-box,twobooksandsomeflowersonthedesk.A.isaB.aresomeC.hasaD.havesome()8.Thereislittlewaterintheglass,____?A.isn‘tthereB.isn’titC.isitD.isthere()9.-Thereisnoairorwateronthemoon.Isthere?-____.A.Yes,thereareB.No,thereisn‘tC.Yes,thereisn’tD.No,thereis()10.-Whatdidyouseeinthebasketthen?-There____abottleoforangeandsomeoranges.A.isB.areC.wasD.were()11.____isthereonthetable?A.HowmanyapplesB.HowmuchbreadC.HowmuchbreadsD.Howmanyfood()12.Thereisn‘t____paperinthebox..Willyougoandgetsomeforme?A.anyB.someC.aD.an()13.There____somethingwrongwithourclassroom.A.areB.hasC.isD.have()14.Thereissome____onthetable.A.appleB.orangeC.cakeD.sandwich
