问题 Without computers, we ______ the tremendous medical advancement in the last few decades.

选项 A、would not make
B、will not have made
C、could not make
D、couldn’t have made

答案D

解析 without作“如果没有”解，表示一种与事实相反的假设，意思上相当于一个if引导的虚拟条件句。根据题中可看出without computer足与过去事实相反的假设，因此主句应该用“would (should，could，might)+动词的完成式”。
