be going to 固定结构,后面要接动词原形. 例句：

一般疑问句 Are you going to have a class meeting this afternoon？
There be句型 表示某处存在某(物)人。

基本结构为“There be +某物(某人)+某地(某时)”。
Be动词的单复数必须依主语的变化而变化。单数is，复数are 如：
There is a table in the room. 房间里有一张桌子。
There are some birds on the tree. 树上有很多鸟。
一、 There be句型的结构：
1.（一）There is+单数可数+地点状语
例：There is a ruler on the desk. 书桌上有一把尺。
（二）There are+复数主语+地点状语
例：There are four apples on the tree. 树上有四个苹果。
There are some flowers in the park. 公园里有许多花。
（三）there is + 不可数名词 +地点状语 （即使有some 也是 单数）
例：There is some water in the bottle. 瓶子里有一些水。（水是不可数名词）
