标题: Prep 1-74

Paleontologist Stephen Jay Gould has argued that many biological traits are not the products of natural selection, favored due to their enhancement of reproduction or survival, but that they are simply random by-products of other evolutionary developments.

(A) due to their enhancement of reproduction or survival, but that they are

(B) due to the reproduction or survival they enhance, but they are

(D) because they enhance reproduction or survival, but are

(E) because of enhancing reproduction or survival, but are

A选项

their(the products of natural selection)和they(biological traits)

同一代名词指代不同所以不选

B选项

两个they所指的东西不一样

第一个they是the products of natural selection

第二个they是biological traits

同一代名词指代不同所以不选

这样的思路有误吗??请各位大牛小牛们指正一下!!

还有关于选项A和B的due to用法实在不是很明白，有人可以解释吗??

(A) due to their enhancement of reproduction or survival, but that they are

(B) due to the reproduction or survival they enhance, but they are

(D) because they enhance reproduction or survival, but are

(E) because of enhancing reproduction or survival, but are

duo to+名词不如 because ＋句子，有效，意思都是因为
D they are not but are ，原因从句修饰are not

这题考的是are...not are结构

due to = caused by, 要能用caused by替换

我觉得你的方法不是很好，因为代词并不是排除grammer最有效的方法，除非非常明显，你可以采用。实际上这道题排除错误的方法有很多，比如due to类似于caused by，不要把它当做because，GMAT中一般都不用due to. 此外，很明显，名词enhancement 不如动词enhance好，所以最后才C和D中选择。考点在于后面的are要不要省略。由于前面是because的从句，所以如果不要are的话，会把but simply random...这部分当做because这句话的伴随状语，破坏平行结构not... but... 所以，选D

Hi, Ellen!
manhattan上的解释：
in that sort of construction, the past participial modifier (the thing starting with "verb-ed") is normally taken to modify the closest noun. in the construction you've drawn up, that noun would be the object.

if you want the construction to modify the subject instead, you should insert it into the main clause right after the subject, using commas to set it off:
"S, verb-ed by blah blah blah, V+O."
按照我的理解：favored在这里作为favor的过去分词，修饰前面的natural selection.意思是：许多生物特点不是自然选择的产物，自然选择被支持是因为这些特点能够加强繁殖和生存能力

明白了。考试时做SC你是以语法为主，还是意思为主？我觉得很多时候句子意思是来不及读明白的，但是会搞清楚结构，比如这里favored整个是个插入语，了解到这步就ok了。你是什么思路呀？

先看完原句，知道大概是什么意思，在看的时候如果发现原句有明显的语法错误就记住，然后再比较每个选项。我一般先采用纵向比较，即每个相似的选项同时看，找出区别，发现有不对的立刻排除。然后采用横向法，把剩下的选项通读进行比较。
