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

解析解此题的关键是要清楚该句是一个隐含了非真实条件句的虚拟句。had they been done by hand是一省略了连词if、主谓语进行了部分倒装的非真实条件句。从该条件句的谓语动词的时态来看，此虚拟句是对过去事实相反的假设，因此主句的谓语动词应该是would (could，should，might等)+动词的完成时，因此，B为正确答案。本题题意为：如果用人工来进行这些数以百万次计的计算，那么当这些计算完成时，它们也失去了任何实际意义。
