86.选项:
(A) which increased 5 percent during the first 3 months of this year after it fell
(B) which had increased 5 percent during the first 3 months of this year after it had fallen
正确(C) which have increased 5 percent during the first 3 months of this year after falling
(D) with a 5 percent increase during the first 3 months of this year after falling
(E) with a 5 percent increase during the first 3 months of this year after having fallen
比较不能理解C中
一:用have increased,现在完成时不是用来1.表明过去某一部确定时间发生的事情2.表面过去发生的某事对现在仍有影响,或仍持续到现在;那这里用现在完成时是表示哪个哩?
二:falling指的是什么时态?答案中要求increase后于fall,falling是否满足了这个要求?
