问题 If this technique should be extended to other crop plants, the rate of production______in this area.

选项 A、will be greatly improved
B、is greatly improved
C、would have been greatly improved
D、would be greatly improved

答案 D

解析虚拟语气题。本句条件状语从句使用的是“should+动词原形”形式，根据句意及该状语从句的形式可知，本句话表达的是与将来事实相反的虚拟语气，故主句用“would／should／could／might+动词原形”，因此D为答案。
