问题
The millions of calculations involved, ______by hand, would have lost all practical value by the time they were finished.
选项
A、had they been done
B、they had been done
C、having been done
D、they were done
答案
A
解析
该题是语法结构题,考查虚拟语气的用法。在该句中,虚拟语气用来表示与过去事实相反的情况,主句用would have done形式,从句用had done形式。引导非真实条件句中的引导词if被省略了,助动词had提前,所以出现了had they been done这样的倒装结构。因此,根据题意和语法规则,选项A为最佳答案。
