| 请教 GWD 24-8 用which +从句 或 with+短语 来修饰名词到底有何不同？
24-8 The results of the company’s cost-cutting measures are evident in its profits, which increased five percent during the first three months of this year after it fell over the last two years.
(A) which increased five percent during the first three months of this year after it fell
(B) which had increased five percent during the first three months of this year after it had fallen
(C) which have increased five percent during the first three months of this year after falling
(D) with a five percent increase during the first three months of this year after falling
(E) with a five percent increase during the first three months of this year after having fallen
ANS：C
任何一题做错我都觉得是我语法上的一个盲点，此题更是如此啊！
D为何错？
(1) C是用which +从句做非限定性定语修饰profits, D 是用with + 短语同样作定语修饰profits 。 D似乎更简洁。
(2) after falling 中after 是介词，故无需考虑逻辑主语， 我的理解对吗？
请NNS指点！ |
