He showed me how to drape the sling over my left shoulder and across the chest so that the pouch lay easily accessible to my right hand, allowing the best in journalism, fiction, and cartoons to be swiftly extracted and sold to a citizenry whose happiness and security depended upon us soldiers of the free press.
这个lay是lie的过去式，是系动词，出于什么状况的意思吗？
网友的理解完全正确。
把lie 归到“系动词”中，把它看作系动词之一。
lie + adj ：“处于某种状况”。
上次给你解答过这个问题，你问的是：accessible to my right hand 是ponch 的定语吗？
lay easily accessible to my right hand：系表结构。
lie （系动词）accessible （形容词）to my right hand
