There be句型是小学英语教学中的重要内容。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）
2. There be选择就近原则：
There be句型的就近原则是There be句型中语法项目的重点考点。There be句型中be动词的单复数形式由最挨近的一项的单复数决定。
如：There is a pen, two books and many pencils on the desk.
在本句中尽管有钢笔、书和铅笔，但是由于离be动词最近的一项是单数a pen，因此，be动词用单数is。
二、There be 句型的疑问句及回答
（一）There be 句型的疑问
1. 在“There is/are...”的疑问句中,要把Be动词放在there之前,并将句号变问号。难点:句中出现的some要改成any。
2. 肯定回答为：Yes, there is/are.
3. 否定回答为: No, there isn’t/aren’t.

三、There be 句型的否定形式
（一）There be 句型的否定： 否定形式只要在be动词后面加not即可，is not =isn’t are not= aren’t
但要注意的是句中如果出现some则改成any.

2.There are five apples on the tree. 否定:There are not five apples on the tree.
3.There is some ink in the bottle. 否定:There is not any ink in the bottle. （ink是墨水，不可数名词）
