A gallery, in its older sense, is a long narrow space. Put targets at the far end of one and people from the near end, and you have the picture this word starts from: a place set aside for shooting down its length, with something waiting at the other end to be hit.
gallery 這個字比較老的意思是「長長的空間」。在它的最裡面擺一排目標，這一頭站著人往那頭打——這就是 shooting gallery 最原始的畫面：一個專門拿來朝目標射擊的長條空間，另一端有東西等著被打中。兩個零件合起來，一個講動作，一個講場地。後面的用法，有的接走「一直朝目標射」這件事，有的接走「一個房間」這個零件。
