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、had lost
B、would have lost
C、would lose
D、should have lost
答案B
解析 本题测试虚拟语气：条件从句使用过去完成时，主句一般使用would have done。例如：I would have been glad if she hadn’t come this morning．如果她今天上午没来，我会很高兴的。The instructions would have been clear enough if only she had spoken in a more distinct voice．如果当时她用清晰的声音说出来，训令就不至于含糊不清。
