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 ourclassroom. 我们教室里有一位老师和许多学生。③ There are two boysand a girl under the tree. 树下有两个男孩，一个女孩。02

there be 句型考点考点一：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，nota/an/any + n. 相当于no+ n.。例如： ①There are some pictures on the wall.→There aren't any pictures on the wall. =There are no pictures on the wall. ②There is a bike behind the tree. →There isn't 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）。①There is some water on Mars. → Is there any water on Mars? ②There 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：①There are many things over there.→What's over there? ②There is a little girl in theroom.→Who is in the room?对地点状语提问：则用where 引导。如：①There is a computer on the desk. → Where is the computer? ②There 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)完成时(there have/has been)还可用there must be ,there can’t be, there used to be等。①--There ___ a concert this evening. --Yeah.Exciting news! A. are going to be B. is goi
