unloading 在此是名词，动词派生的名词若要带自己的逻辑宾语，必须用“the unloading of + 宾语”结构，of 不可省略。中文“卸货”把宾语直接放在动词后，没有介词标记，所以学习者常漏掉 of。

中文“卸载”既可用于货物，也可用于软件，但英语 unload 只表示卸下货物或减轻负荷；删除手机、电脑上的应用程序要用 uninstall，不能用 unload。
loading 指把货物装上车、船或容器，方向与 unloading 相反；unloading 指把货物从运输工具或容器中卸下。两者都可作名词，但动作方向相反，不能混用。
offloading 与 unloading 在“卸货”义上常可互换，但 offloading 更强调把负担转移出去，也常用于责任、风险或业务；单纯说从车、船上卸下货物时，unloading 更直接常用。
