If the whole operation__________beforehand,a great deal of time

If the whole operation__________beforehand,a great deal of time and money would have been lost.
A、was not planned
B、has not been planned
C、had not been planned
D、were not planned
【正确答案】：C
【题目解析】：【考情点拨】考查虚拟语气。【应试指导】句意：如果事先没有计划好整个运作，大量的时间和金钱将会流失。由would have?been lost可知此处表示与过去事实相反的虚拟语气．从句中应使用“had+过去分词”。
