1、Therebe句型专题复习授课教师：大宇小学　李　霞概念结构用法Therebe句型表示“存在…”“有”，其中be动词有时态和单复数变化。Therebe+主语（人或物名词）+地点一、知识点回顾1、看名词单数is复数are不可数的用is看名词There_____adollinthetoybox.A.isB.areThere_____somebreadontheplate.面包（不可数名词）A.isB.areThere_____alotofgreentreesinthePark.A.isB.areThereisacatunderthetree.Therearetwodogs

4、erearen’t.规则：is/are要提前,some变any,其他都不变．二、Therebe句型的转换变一般疑问句并作答：Thereisastory-bookinmybag.Isthereastory-bookinyourbag?Yes,thereis.／No,thereisn’t.Therearesomephotosonthewall.Arethereanyphotosonthewall?Yes,thereare.／No,therearen’t.2、否定句Forexample:1.Thereisagyminourschool.→Thereisn’tagyminour

5、school.2.Therearesomebooksonthedesk.→Therearen’tanybooksonthedesk.3.Therewasabuildingneartheriver.→Therewasn’tabuildingneartheriver.Therebe句型变否定句，一种只要在be动词后面加上not,遇上some就变为any；另一种就是在主语（即名词）前加上不定代词no。例如：Therewerenocomputersthen.Let’stry将下列句子变为否定句1.Thereisaneggintheplate.→Thereisn’taneggin

6、theplate.（or）Thereisnoeggintheplate.2.Therearesomebirdsinthetree.→Therearen’tanybirdsinthetree.（or）Therearenobirdsinthetree.Therebe有特点，主语放在be后面，单数主语用is，复数主语要用are。变否定很简单，be后要把not添。变疑问也不难，把be提到there之前。否定疑问any换，就近原则多多练。Therebe口诀三、复习小结Therebe句型和have的区别相同点：都有“有”的意思。不同点：用法不同，Therebe表示某个时间或某个地方
