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。
