问题 Without electronic computers, much of today’ s advanced technology______.
选项 A、will not have been achieved
B、have not been achieved
C、would not have been achieved
D、had not been achieved
答案C
解析 本题考查虚拟语气的用法。句意：要是没有电子计算机的话，现在的很多先进的技术就无法获得。without引导的介词短语表示潜在的一种假设，相当于if引导的条件状语从句，即：Without electroniccomputers=If there were not electronic computers。由于主句中的情况早已经发生，所以这是对过去情况的一种假设，故主句的谓语动词为“would+have done”。故选C。
