There be句型被动式如何划分句子成分
下面这个句子，在 there be 之间插入了 are known to：
There are known to be thousands of different species of beetles.
类似的好像还有：
There was said to be a fire in that building last night.
引句中在 there be 之间插入了 was known to。
请问：上面两句中的 thousands of different species of beetles 和 a fire 是什么句子成分？是主语吗？
