看答案
bound
had 後接過去分詞構成過去完成式，因此選 bound。bind 是原形，binds 是第三人稱單數現在式；binding 是現在分詞，不能直接放入此處的 had ____ 結構。
同義改寫
During the rehearsal, the stunt performer crossed the gap in a single bound. → During the rehearsal, the stunt performer crossed the gap in a single leap.
此處 bound 是一次向前的大跳躍，single leap 保留一躍跨過缺口的意思。
The metal rods were tightly bound together with straps before shipment. → The metal rods were tightly tied together with straps before shipment.
此處 bound 指用束帶綑綁的狀態；tied 保留固定方式、緊度及出貨前的時間資訊。
