一道英语选择题...虚拟语气If the whole operation ______ beforehand, a gr

我觉得应该是，had not been taken in,你这个答案确实有问题，刚我在网上搜了一下，原题是 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 答案选的C，希望能帮到你，你可以找个时间和老师讨论一下。
