为什么是there being no classes yesterday,we paid a visit to the Great wall
而不是there was no classes yesterday,we paid a visit to the Great wall

这个是独立主格的现象,逗号不能同时连接2个句子,一整个句子的主语只能有一个,所以前面的be动词要接ing的形式,否则一句话里面有2个主语了,就像这句话是一样的道理:
It being Sunday,we can play football outside home.
若是将逗号改成and的话就可以直接用be动词了,这样就是一个主语,两个谓语动词都是用来修饰这一个主语的。

there was no classes yesterday,and we paid a visit to the Great wall
两个句子不能用逗号连接

There being 是独立主格。。用途为原因状语。
下面的一句话,we paid a visit to the Great wall because we have no classes yesterday.这样写就对了

因为主语是we,there was no classes yesterday,we paid a visit to the Great wall这样的话有两个主语了
there being no classes yesterday作为时间状语从句
