怎么理解此处省略have been ，直接用falling ,有什么依据吗？作者: Serena11457 时间: 2012-5-29 20:39
其实这题通过时态，必须用现在完成时，就锁定C（排除D/E两项with结构，因为ambiguity），lz问得很好！我个人理解，此处falling作为名词(action noun)理解，就避开了棘手的时态问题。
而且就算用动词fall的某种时态形式，也是
....in its profits, which have increased ... during ... after they ....
这里which从句，which指代profits，然后后面又出来they指代profits，很awkward.
所以就干脆用after falling...falling作为名词，来回避after+从句里面从句的问题，而且这表达很准确很简洁。
不知道这样理解对么，请NN指点作者: dumengxuan 时间: 2012-5-30 06:37
