以下是引用tianwan在2004-1-29 21:45:00的发言: In fact, I had also choosed answer A. However, after I had reconcider the standard answer, I found choice D applies absolute structure(独立主格结构), so it avoids the confusion of a preposition phrase that no subject is available for the preposition phrase. 'with' can actually be omitted.
As for choice C, 'see' is a stative verb, which is not available in present tense, not to say perfect present tense. Moreover, 'are marker of' is not as concise as 'mark'.
Is my opinion right? 虽然大全解释上说: Kaplan gmat 800上答案是A 解释抄录如下: The key to getting the right answer for this question is recognizing that the underlined portion of the sentence should not contain pronoun. The answer choices give you the option of replacing with different colors with whose different colors but the second option is wrong because, if you added whose, it could refer to thelayers or the Canon, and whenever a pronoun has more than one possible antecedent (the thing it refer to), it's used incorrectly. Eliminate (B) and (C). (A) is correct. Eliminate (E) as well because the subject of "marking" is similarly unclear; is it the layer or the Canyon this is marking the passage of time? And (A) is better than (D) because, once again, see is better than the wordier alternative been able to see. 虽然我认为正如Kaplan所说, D的been able to se很罗嗦,但是问题在于A的with结构修饰是否适当? 我认为应该是D,这里的考点是到底用with的独立结构还是用with+N 从我看到的有限的OG+大全的例子, 我的感觉是:with+N,可以作状语,也可以作定语;在with前部如果有动词结构时,优先考虑with作状语,修饰前最近的一个主谓结构,这里所指的主谓结构不一定是主句主语和主句谓语,因为更靠近with的完全有可能是子句的主语和动词。(结合了NN的小结) 而 with 还有另外一种结构, 独立主格结构, 其形式为with + n+n/分词/介词短语/形容词/形容词短语 (本题也就是D的结构), 两种结构在修饰上的差别是 前者不可以跳跃修饰, 后者可以(动物园里猴子吊在树上的那题) 而这个恰好是A和D的区别, A用的就是 with+N根据上面的原则,其修饰基本上是修饰主谓结构,也就是those See,歧义, 而D是独立主格结构,可以跳跃,修饰layer 所以我支持D(尽管有albe的罗嗦,但至少没有歧义)
