独立主格结构That being my first visit to it,I didn't know where I should go first.
being为什么不能换成to have been
独立主格结构That being my first visit to it,I didn't know where I should go first.being为什么不能换成to have been
1.to have been...是不能用于独立主格结构的.
要使用不定式的话,一般只能是：to be...
2.但是如果该句改成：That to be my first visit to it,I didn't know where I should go first.
则此句错误.
3.因为不定式用在独立主格结构中,表示该动作尚未发生.
如：That to be my first visit to it,I decided to buy a map first.
4.但是该题根据I didn't know where I should go first可以看出,my first visit所表示的动作已经发生,所以用不定式是错误的.
独立主格结构 没有 主格+不定式的。
“独立主格结构”是由名词或代词作为逻辑主语，加上分词、形容词、副词、动词不定式或介词短语作为逻辑谓语构成。
that是逻辑主语 being分词是逻辑谓语
这里是表状态 用ing分词
这里的being,是修饰that的....一般独立主格结构只有+ed,+ing两种形式
