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

根据语意，应该是profits增加吧，那么用which可以比用with指代的清楚，逗号加介词短语如果语意没有问题的时候最好不要选。

over the last two years

感觉这个前面应该用having fallen才对。。。为什么用falling 也可以呢....
with 从句仔细看了看也不好，因为after之前和之后的结构不对称，还是c好，除了那个falling不是很明白之外......

因为AB里的it不能指代复数名词profits

1.不选E的原因是，e把定语从句变成了with+N+介词短语的独立主格结构，而独立主格结构是做

状语的，修饰主句，表示伴随原因，状态，条件等。要知道，没有合理的理由，定语和状语是最好

不要乱变的。并且，after having fallen 是状语从句的省略形式。有两种找逻辑主语的方式，我

就不多说了。总之在e中找不到逻辑主语。
2.选C好是因为，have increased 和fall 表明了时间的先后顺序，并且这种没有用逗号隔开的状

语从句省略形式的逻辑主语就是就近动词的逻辑主语。所以说没有逻辑上和语法上的错误。另外说

一点，如果状语从句的省略形式前面有逗号隔开，比如.... , after falling.这种，那么他的逻

辑主语就是主句的主语。
