人教版七年级英语下册Therebe句型中鸡中学李磊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+某地”。其中there是引导词,没有词义;be是谓语动词;“某人或某物”是句子的主语;“某地"作句子的状语,多是介词短语。如:Thereisafootballunderthechair.主语介词短语椅子下面有一个足球。Therebe结构中的动词be的确定1.therebe结构中的谓语动词be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,是复数时用are。如:Thereisaflowerinthebottle.瓶里有一朵花。Thereissomemoneyinthepurse.钱包里有些钱。Therearesomebooksonthedesk.桌子上有许多书。2.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。如:Thereisaboy,agirlandtwowomeninthehouse.房子里有一个男孩,一个女孩和两个妇女。Therearetenstudentsandateacherintheoffice.办公室里有十个学生和一个教师。Therebe结构中的动词be的确定Therebe结构的句型转换否定句therebe的否定式通常在be后加not构成(在口语中be时常与not缩写在一起)。如果句中有some,一般要变成any。如:Therearesomechildreninthepicture.→Therearen'tanychildreninthepicture.Therebe结构的句型转换一般疑问句及其答语把be提到there前,首字母大写,句末用问号即可。其肯定答语是Yes,thereis/are;否定答语为No,thereisn't/aren't。如:Therearetwocatsinthetree.—Aretheretwocatsinthetree?—Yes,thereare.(No,therearen't.)树上有两只猫。“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。1.There_____aclockonthetable.A.isB.are2.______therearadioonyourdesk?A.areB.is3.____thereamaponthewall?Yes,there______.A.are/isB.is/areC.is/isD.are/are4.There_____somestudentsintheclassroom.A.areB.is5.There_____apencil,abookandtwopensonthetable.A.isB.areABCAA6.There___twoapples,oneorangeandonebananaonthetable.A.isB.are7.Arethere___picturesonthewall?No,therearen't___.A.any/anyB.some/anyC.some/someD.any/some8.Thereisn'tabookinhishand.Thereis_____bookinhishand.A.noB.not9.Thereisatree____theplayground.A.atB.near10.--Arethere_____shopsnearhere?--No,thereare_____shopsnearhere.A.some,notB.some,anyC.any,notD.any,noBABAC教室里有很多桌子和凳子。Therearesomedesksandchairsintheclassroom.书架上有很多书。Therearesomebooksontheshelf.椅子下有个足球。Thereisafootballunderthechair.树上有两个风筝和一只鸟。Therearetwokitesandabirdinthetree.Thereisabirdandtwokitesinthetree.房子附近有三棵树。Therearethreetreesnearthehouse.1.Thereisamouseintheroom.(改写为一般疑问句，并作肯定否定回答)Isthereamouseintheroom?Yes,thereis./No,thereisnot.2.Thereisafishinthebowl.(改写成否定句)Thereisnotafishinthebowl.3.Therearesomedolphinsintheocean.(改写为一般疑问句)Arethereanydolphinsintheocean?4.Therearesomebooksinhisbag.(改写为否定句)Therearenotanybooksinhisbag.用所给词的正确形式填空1.There____(be)apenandtwopencilsinthepencil-box.2.Howmany____(watch)arethereinthesupermarket?3.There_______(be)somebreadontheplate.4.There_______(be)apairofglassesonthedesk5.There_________(benot)anyriceinthebowl.6.__________(therebe)sometreesinourschool.7.————————(therebe)anycrayonsonthebook?iswatchesisisisn'tThereareArethere8.Howmanypeople________________(bethere)inyourfamily?9.___________(therebe)somericeinthebowl.10.__________(therebe)anappleandsomepearsonthetable.11.___________(therebe)someapplesandapearonthetable.12.___________(therebe)twobedsintheroom?No,___________.arethereThereisThereisThereareAretheretherearen'tGoodbye
