英语there这个单词，都怎么用啊？

there to be/being结构可作主语、状语或动词、介词的宾语，但要注意作主语和状语时there to be前用for引导，作宾语时则无for。例如：

In that case it is impossible for there to be an escape from the building. 在那种情况下根本没有从楼里逃出的可能性。

It was too late for there to be any buses. 太晚了，不会有公共汽车了。

I never dreamed of there being a chance for me to be sent there. 我压根就没有梦想会有被派往那里的机会。

There being no buses, they had to go on foot. 由于没有公共汽车，他们只得步行。（独立主格结构表原因）

独立主格结构是高中语法的一个难点。

独立主格结构的逻辑主语与句中语法主语不同。
独立结构在句子中作状语，其构成有如下集中形式
1.名词（代词）+不定式或分词。如：
The problem being settled, we ended our meeting.
We devided the work, he to clean the windows and i to sweep the floor.
The clock having struck 12, i went to bed.
2.名词（代词）（+being）+形容词、副词或介词短语；如：
I saw deep pools, the water blue like the sky.
The condition(being)favourable, he may succeed.
Summer over, students retruned to school
Then, last night, I followed him here and climbed in, sword
