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 overthe last two years.  

A.    which increased five percent during the first three months of this yearafter it fell
B.    which had increased five percent during the first three months of thisyear after it had fallen
C.    which have increased five percent during the first three months of thisyear after falling
D.     with a five percentincrease during the first three months of this year after falling  
E.    with a five percent increase during the first three months of this yearafter having fallen


正确答案是C
A如果改成     which have increased five percent during the first three months of this year after they fell  是不是就对了？

同问。

我个人认为，
1）状语从句中，逻辑主语相同，可省略
2）after本身就产生了时间阶梯，所以after后的动词就不必再用时态来表达时间阶梯。

等NN来解答！

正确答案after 在这里做介词不是做连词。 after falling overthe last two years 是来修饰分句which have increased five percent during the first three months of thisyear 。  如果按照搂主改法，把after 当连词用，我觉得语法上没啥问题， 但是语义的重心发生了转移（由原来强调今年头三个月涨了5个点 变成了强调 两个事件时间顺序“利润头两年一直跌之后 最近3个月开始涨”）

希望nn也帮忙从语法看看楼主句子有没有问题。

但这个题目不是本来就是比较想要强调时间先后顺序的吗？先有下滑两年，再有上升

这句话整个强调的中心是主句。非限制定语从句修饰利润。定从句里想强调的是增长，以配合前面提到的那个 measures的优点。即这个measure使得利润增长了。而增长之前下降则不是强调的重心。
after doing 是最完美的用法。这种形式本来已经强调出了时间顺序。after doing 是说前面那个动作之前，一直在干嘛。
这种有种延续性的动作在里面，也就是增长之前一直在下降。和后面的over xx years对应。
鉴于over the last two years.  如果lz非要改的话，应该说成after they had xxx.（b的后边）才能强调延续性的动作。这里显然没有 after doing好。像lz一样 直接一般过去时更强调了某个时间点而非时间段了。
本来简洁的东西说复杂了，而且引入了多余的代词，让读者还要回到前文去找发出者。典型的wordy

个人理解，经供参考。

非常清楚~~！我只知道过去时代表过去的动作，而不知其强调某个时间点。谢谢！
