问题 Even though its per capita food supply hardly increased during two decades, stringent rationing and planned distribution have allowed the People’s Republic of China to ensure nutritional levels of 2,000 calories per person per day for its population.
选项 A、Even though its per capita food supply hardly increases during
B、Even though its per capita food supply has hardly increased in
C、Despite its per capital food supply hardly increasing over
D、Despite there being hardly any increase in its per capita food supply during
E、Although there is hardly any increase in per capita food supply for
答案 B
解析 根据上篇所述GMAT公理，C、D的despite+名词这种复杂结构应换用although、though等引导的让步从句，而A、B、E最大的差异在于时态。通过未划线部分的two decades及主句中的have allowed可以断定Even though让步状语从句中的时态应与主句一致：用现在完成时，为什么?因为two decades是一个时段，无论A中的increased或E中的is都无法与此时段匹配，无法表明持续性的动作，再排除A、E，选B，用现在完成时。B中做了个小的改动，用in替换during，因为during时间短语较少与现在完成时连用，而in短语却通常与现在完成时态连用。
