初中there be 句型用法及配套练习 一:there be 句型基本认识 1、 定义:There be句型表示某处存在某物或某人。 2、结构:(1) There is +单数可数名词/不可数名词+ 地点状语. (2) There are +复数名词+地点状语. 注意事项: there是引导词,在句中不充当任何成分,翻译时也不必译出。句子的主语是某人或某物,谓语动词be要与主语(某人或某物)的数保持一致。当主语是两个或两个以上的名词时,谓语动词要与跟它最近的那个名词一致。如: ① There is a bird in the tree. 树上有一只鸟。 ② There is a teacher and many students in our classroom. 我们教室里有一位老师和许多学生。 ③ There are two boys and a girl under the tree. 树下有两个男孩,一个女孩。 二: there be 句型的常考点 考点一:各种句型转化。 1:变成否定 There be句型的否定式的构成和含有be动词的其它句型一样,在be后加上not或no即可。注意not和no的不同:not是副词,no为形容词,not a/an/any + n. 相当于no+ n.。例如: There are some pictures on the wall. →There arent any pictures on the wall. =There are no pictures on the wall. There is a bike behind the tree. → There isnt a bike behind the tree. =There is no bike behind the tree. 2:变成一般疑问句 There be句型的一般疑问句变化是把be动词调整到句首,再在句尾加上问号即可。但同时要注意:当肯定句中有some时,要将其改为any(否定变化也一样)。 There is some water on Mars. → Is there any water on Mars? There are some fish in the water. →Are there any fish in the water? 3:特殊疑问句 对主语提问:当主语是人的时候,则用who 引导,当主语是物的时候,则用what 引导。注意:无论原句的主语是单数还是复数,对之提问时一般都用be的单数形式(回答时却要根据实际情况来决定)。如: There are many things over there. →Whats over there? There is a little girl in the room.→Who is in the room? 对地点状语提问:则用where 引导。如: There is a computer on the desk. → Where is the computer? There are four children on the playground. →Where are the four children? 对数量提问:般有两种句型结构: How many+复数名词+are there+介词短语? How much+不可数名词+is there+介词短语? 考点二:there be 句型的时态。 be可以有现在时(there is/are)、过去时(there was/were)、将来时(there is/are going to be或there will be)和完成时(there have/has been)如: ---There ______ a concert this evening.---Yeah. Exciting news! A. are going to be B. is going to be C. is going to have D. will have 考点三:there be 句型反意疑问句的构成:be (not) there?如:There is some milk in the bottle, ____ ? A.isnt there B.arent there C.isnt it D.are there 考点四:there be 句型的主谓一致: There be 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。如: 1.There ___ any rice in the bowl.
