1．There be结构中的be是谓语动词，它在人称和数上应和其后的主语（名词）保持一致，即主语是不可数名词或单数可数名词时用is，复数时用are。例如：
There is a bird in the tree．树上有只鸟。
There is some meat on the plate．盘里有些肉。
There are some people in the room．屋里有些人。
若be后有两个或两个以上的名词作主语时，be动词应采取“邻近原则”，即be应与邻近的主语在数上保持一致。例如：
There is a pen and two rulers in the pencil-box．文具盒里有一支钢笔和两把尺子。
There are three apples and a pear in the basket．篮子里有三只苹果和一只梨。
2．There be结构中的谓语动词有时不用be，而用其他动词，使语言表达更生动形象，如live，stand，lie等词。例如：
Long，long ago，there lived a king．很久以前有一个国王。
There stands a school on the hill．山上有所学校。
3．There be结构常见时态有一般现在时、一般过去时、一般将来时、现在完成时等，其时态的变化都是通过be动词来完成和体现的。其具体形式如下：
|
时态 |
谓语动词 |
例句 |
| 一般现在时 | are/is | There are two chairs in the room. |
| 一般过去时 | were/was | There was a bike near the house a moment ago. |
| 一般将来时 | will be/is(are)going be |
There will be a meeting tomorrow afternoon. There are gong to be two football matches. |
| 现在完成时 | have/has been | There have been GREat changes in my hometown. |
此外，There be结构还可以和情态动词连用，表示推测。例如：
There must be no one in the room．屋里肯定没人。
