There be 句型 There be句型是常见的表示人或物“存在”的句型，在汉语中译为“有”。它以否定句的形式出现，用于对某一具体行为和抽象概念的否定。这类句中往往会有一个介词短语来表示位置或地点。 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. 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 aren't any pictures on the wall. =There are no pictures on the wall. There 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）。 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 （1）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. →What's over there? There is a little girl in the room. →Who is in the room? （2）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? 介词短语： 构成：介词+the+方位词 如： on the right （le
