一道英语选择题...虚拟语气
If the whole operation ______ beforehand, a great deal of time and money would have been lost.
正确答案是have taken in,请问是不是答案错了?与would have done对应的怎么可能是have done.

这是个虚拟语气.因为显然a great deal of time and money would have been lost这个事情没有发生.而且这是一个对过去的虚拟.结构为if +过去完成时,xx情态动词的过去分词+完成时..
这道题的选项有哪些
再问： 另外三个是was not planned, has not been planned和were not planned。我选了第三个。
再答： 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。
