问题 The millions of calculations involved, had they been done by hand, ________all practical value by the time they were finished.

选项 A、could lose
B、would have lost
C、might lose
D、ought to have lost

答案B

解析 本题考查虚拟语气。had they been done by hand是一个省略了连词if的倒装的虚拟条件句,时态为过去完成时态,即表示与过去事实相反,故主句和谓语应该用would have done的形式,故答案为B项。
