The calculations, had they been done by hand, all practical value by the time they were finished.A．had lost B．would lose C．should have lost D．would have lost 题目和参考答案——青夏教育精英家教网—

The calculations, had they been done by hand, ______all practical value by the time they were finished.

A．had lost

B．would lose

C．should have lost

D．would have lost

解析试题分析:句意：这些计算如果用手工进行的话，那么当他们完成后将失去所有的实际价值。句中had they been done是if they had been done的省略，是对过去的虚拟，所以主句谓语应该用would have done，选D。
考点：考查动词时态。
