Digging in sediments in northern China, evidence has
been gathered bv scientists suggesting that complex
life-forms emerged much earlier than they had
previously thought.
(A) evidence has been gathered by scientists suggesting that complex life-forms emerged much earlier than they had
(B) evidence gathered by scientists suggests a much earlier emergence of complex life-forms than had been
(C) scientists have gathered evidence suggesting that complex life-forms emerged much earlier than
(D) scientists have gathered evidence that suggests a much earlier emergence of complex life-forms than that which was
(E) scientists have gathered evidence which suggests a much earlier emergence of complex life-forms than that
求问这道题的D E选项 that which和that怎么不对了。。。
我在beat the gmat上找到了这一个解释
(D) scientists have gathered evidence that suggests a much earlier emergence of complex life-forms
than the emergence which was previously thought
First off, it's an incorrect modifier "which" (requires a comma). But beyond that, the logic here is doesn't make any sense. We want to be comparing times, not some specific emergence. Do you see how the word "that" creates a specific emergence we're comparing to. But that's not right.
(E) scientists have gathered evidence which suggests a much earlier emergence of complex life-forms than the emergence previously thought.
In both of these, the correct comparison would be the equivalent "I ate an earlier breakfast than I did most days" not "I ate an earlier breakfast than that I ate most days."
In the second example, "that" refers to a specific breakfast, which makes no sense.
想知道是怎么知道emergence是specific的
这个比较不就是比较emergence的早晚么....... |
