there be 结构中be动词既有“数”的变化，也有“时”的变化。be动词作谓语时，其用法可参考下表。

there be结构的用法

1. There is a book on the desk.

2. There are two pencils and a pen in Tony's pencilbox.

注意:therebe结构中的“就近原则”。be动词变化取决于离它最近的名词，如上句中be动词距离two pencils要近，则用are。下句中be动词距离a pen近，则用is。

There is a pen and two pencils in the box.

3. There was no gym in my school ten years ago.

4.There were two old buildings in the yard.

5. There will be/is going to be a movie this evening.

6.There will be /are going to be two bridges in the town.

7.There has been a terrible rumor in the factory.这个工厂里一直有个吓人的传言。

8. There have been lots of great inventions that change the world.

不断有了不起的发明改变着我们的世界。

后记:以上是there be结构中be动词作谓语时的变化，实际上，there be结构中be动词还可以做非谓语动词使用，在此不加累赘了。

题主可以随着自己学段及知识水平增加不断积累总结。

希望对你有帮助哦！

be一般现在时is/are，一般过去时was/were，一般将来时will be，过去将来would be，完成时have/had been。

There be句型讲究的是就近原则。
如果后面的名词是单数，be就用单数(is)
如果后面的名词是复数be就用复数(are)
还要考虑时态
过去式就用was/were
