Dr. Munoz______experimental methods for obtaining energy from natural sources long before GDS Incorporated developed its own.
选项
A、is devising
B、had devised
C、was devised
D、has devised
答案
B
解析
从句“long before…own”中使用了状语从句引导词before(在……前),可知主句中提及的事情发生在从句的动作之前。为表达在过去特定的时间点(GDS公司发展自己的方式)之前发生的事(穆诺茨博士研究获得能源的方法),应用过去完成时。因此过去完成时(B)had devised为正确答案。空格后有动词宾语experimental methods,故被动语态(C)不正确。
