OG12 86 时序关系是如何体现的？

86. The results of the company’s cost-cutting measures are evident in its profi ts, which increased 5 percent during the fi rst 3 months of this year after it fell over the last two years.

(A) which increased 5 percent during the first 3 months of this year after it fell

(B) which had increased 5 percent during the first 3 months of this year after it had fallen

(C) which have increased 5 percent during the first 3 months of this year after falling

(D) with a 5 percent increase during the first 3 months of this year after falling

(E) with a 5 percent increase during the first 3 months of this year after having fallen

答案是C。

不明白“have increased 5 percent during ”和“after falling”这两个时态的选用。 谢谢！

search...這GWD題被討論多次 ;-)

search好像也不是个容易的事情，我刚好也遇见这个问题，分享下：GMAT的语法严谨，这里主要是考察多个动作发生的先后或者逻辑关系。考点是，increase和fall之间的先后，明显fall先发生，increase后发生，因此a没有体现出来。当然从做题的角度讲，有个“it”帮助筛选答案，which引导的从句中主语应该是承接前面profits（复数），所以有it的都不合适

自己解释之后都觉得又有点心虚了，在google上搜了下，发现某个人的答案我比较欣赏：1）全句的时态应该是现在时（和主句一致）2）如果用with的话，不能表示增加的5%的profit都是由cost cut导致的，有可能只是5%的一部分。原文如下........profits, with a five percent increase ....' : This can be interpreted as profits with a five percent increase (in sales or in population or might be anything). D/E does not associate ' a five percent increase' with 'its profits' clearly.

按照OG的解释：
“The sentence therefore needs to clarify the sequence by presenting the first-identified indicator in a clause with a verb tense that indicates a later time period than the verb tense in the clause presenting the second-identified indicator. ”
也就是说：“上升5 percent”的现在完成时have increased  晚于 “持续走低”的现在进行时falling。
也就是说OG的意思是：现在完成时 晚于 现在进行时
这个逻辑我怎么都想不明白。。。。
高手救命啊～～～～～

如果“现在完成时” 晚于 “现在进行时”，那过去完成时和过去进行时呢？
想到OG 12 SC 90：

Although early soap operas were first aired on evening radio in the 1920s, they had moved to the daytime hours of the 1930s when the evening schedule became crowded with comedians and variety shows.

(A) were first aired on evening radio in the 1920s, they had moved to the daytime hours of the 1930s
(B) were first aired on evening radio in the 1920s, they were moved to the daytime hours in the 1930s
(C) were aired first on evening radio in the 1920s, moving to the daytime hours in the 1930s
(D) were aired first in the evening on 1920s radio, they moved to the daytime hours of the 1930s
(E) aired on evening radio first in the 1920s, they were moved to the 1930s in the daytime hours

正确答案是C。

在OG的解释里有这么一句话，说明题目的时态：
“The past perfect had moved indicates action completed before the action in the simple past were aired, suggesting illogically that the 1930s were finished  sometime during the 1920s.”

这是不是说明“过去完成时” 早于 “过去进行时”啊？
这不就跟86题不一致了么。。。。。
是不是不能这么简单的比较过去和现在两种时态啊？

nancyyen

这个答案是B。。。

sorry, 看成第86了。。。
额 但是问题还是照旧呀～～

同问这个时序关系
不是有after来体现后increase先fall了吗?

按照OG的解释：
“The sentence therefore needs to clarify the sequence by presenting the first-identified indicator in a clause with a verb tense that indicates a later time period than the verb tense in the clause presenting the second-identified indicator. ”
也就是说：“上升5 percent”的现在完成时have increased  晚于 “持续走低”的现在进行时falling。
也就是说OG的意思是：现在完成时 晚于 现在进行时
这个逻辑我怎么都想不明白。。。。

同问！这个题同时是GWD24的第8题，论坛上有很多关于这道题的讨论，但是我看了几乎所有的帖子，都没有能解释这个问题的。。。。
