句子分析 I was a bit nervous before I arrived here ,but there is no reason to be.
I was a bit nervous before I arrived here ,but there is no reason to be.to be在这里什么作用?不要to be 这个句子不是也可以吗?

I was a bit nervous before I arrived here ,but there is no reason to be it
这应该是原句,原句已经省略了it
在这里it代替前面的句子
to be在这里做的是宾语补足语
补充说明的是从句谓语现在的状态,不可省略
