标题: 【救助】OG12-86 PREP语法笔记解答疑问求解！

86.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

答案是C

prep2008语法笔记里的解释我有一处看不懂

说A选项 increased 和 have increased 都可以
那请问 over the last two years 不是只能用现在完成时吗？如果increased可以不是矛盾了吗

有没有人回答一下疑问谢谢！！

好吧没人解答但我自己搞明白了= = during the first three months 和 over the last two years 都是现在完时的标志，但在本题的语境里 increse 和 fall 有明显的先后顺序所以不可以都用现在完成时
此时可以将after falling 作为increse时间点的一个 modifier

86.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（第二个it这里指代company句意错误）
B. which had increased five percent during the first three months of this year after it had fallen（无根据的添加过去完成时）
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（after是主句的状语从句，主语是result，所以逻辑错误）
E. with a five percent increase during the first three months of this year after having fallen（同上）

至于over要不要用完成时，我觉得并不是一个必错的问题，只是一个更加好的用法罢了。而it代词指代出现错误是不可原谅的问题。
