一个英语句型,
But it is a little upsetting to read in the explanatory notes that a certain line describes a fight between a Turkish and a Bulgarian officer on a bridge off which they both fall into the river
请问这个是什么结构,其中it指代什么,that是同位语吗?

explanatory notes 是注释说明的意思
注释说明中有那么一行专门描述两个分别来自土耳其和保加利亚的军官在一座桥上打架结果掉到河里的事,读到这儿时,真让人觉得苦恼\沮丧.（总的是个形式主语和真主语的问题,it 是形式主语；that 是read 的宾语）
分析如下：
主干：it is a little upsetting to read that...
宾语从句：that a certain line describes a fight between a Turkish and a Bulgarian officer on a bridge off which they both fall into the river
介词+关系代词引导的定语从句：off which they both fall into the river（which 指bridge桥）
in explanatory notes 是表示地点的介词短语,指所读内容的出处
