问题 If the whole operation______(没有预先计划), a great deal of time and money would have been lost.
选项
答案had not been planned beforehand
解析 “预先计划”用be planned beforehand表达。该句横线部分位于条件状语从句中，后面是主句。主句部分使用了would+完成时态的虚拟语气的形式，故前面的条件句的时态应该为过去完成时，且其主语operation是动词“计划”的承受者，所以此处应填过去完成时的被动语态的形式，故答案为had not been planned beforehand。
