摘要：The millions of calculations involved, had they been done by hand, all practical value by the time they were finished. A. could lose B. would have lost C. might lose D. ought to have lost 解析:这个句子中含有一个省略if.把助动词提前到主语they之前的虚拟条件句.该条件句表示对过去情况的假设.而主句中by the time they were finished 表明主句也应该是对过去发生的情况的假设.因而应该选(B)would have lost为正确答案.
