[SC总结] 请教 GWD 24-8 用which +从句 或 with+短语 来修饰名词到底有何不同？

24-8 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

ANS：C   

任何一题做错我都觉得是我语法上的一个盲点，此题更是如此啊！

D为何错？

(1) C是用which +从句做非限定性定语修饰profits, D 是用with + 短语同样作定语修饰profits 。 D似乎更简洁。

(2) after falling 中after 是介词，故无需考虑逻辑主语， 我的理解对吗？

请NNS指点！

1. with放在句末与主句之间有逗号隔开，一般是引导独立主格结构，修饰整个句子或主句的主语。

2.关于时态问题，偶觉得这题来看是选项比较的结果。

一般来讲，一个句子使用一个时态，要么都是现在时(包括一般现在时，现在进行时，现在完成时)，要么都是过去时(包括一般过去时，过去进行时，过去完成时)，例外情况有：

1)　如果动词有自身的时间状语，动词的时态应跟自身的时间状语保持一直；
2)   下列情况要用一般现在时：a. 客观事实；b.政府的决策行为；c. 科研成果，统计资料；d. 直接引用(注意，这里的直接引用不同于偶们以前学的语法－－直接引用要加双引号，即GMAT中的直接引用不加双引号。)

sorry, LES,

本句有两个时间状语during the first three months 和 over the last two years   

我想确认一下，是否由于increase 一定在fall 之后所以决定了从句的主句用现在完成时，可是问题是falling是否也有一直在进行的意味呢

实在抱歉，我对时态总是很迷糊，希望您能在指点一下

I search in google, find one sentence like below, 而且很多商业性的文章都出现过类似的句子

After having fallen sharply over the preceding two years, new orders for capital equipment stabilized and, for some categories, turned up in nominal terms in 2002

but I can not find any sentence like after falling over the last ___Years

还是认为 over the last few years 是完成时的标志

承认C选项which 指代没有问题，可是时态不对呀，前面是现在完成时表示到现在为止都这样，后面是falling，falling 有正在进行的意味，不可能profit同时又升又降吧

还是认为是E，独立主格也可以修饰整个句子呀

Listen to LES, she's right.

1. 当 with 短语放于句尾时，其逻辑主语不明。既可以修饰主句的主语，也可以解释里其最近的名词。

2. C 中的完成时时根据 during the first 3 months of this year 来确定的，over the last 2 years 仅定义了

    fell.

Pay attention the logic and sentence's meaning. Don't fracture the sentence to meaningless grammar parts.

Get to know the sentence First as a whole and Second as a simplified structure.

可是问题是profit不可能同时又升又降啊

你真的确定独立主格要求逻辑主语吗

个人认为从逻辑意思上，E更通顺

因为after 后加上现在完成时，其实就是过去完成的意思，而记得白勇的语法书里非常明确地指出

如果是over +the last+时间短语，就是现在完成时标志

况且LES也没有肯定这里有逻辑主语的问题这种说法呀

再者 during +the first three months 可不是完成时的标志呀

after having done 在google里比比皆是
