考前语法求助！prep题

nnii

43. 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

C because they enhance reproduction or survival, but

D because they enhance reproduction or survival, but are

E because of enhancing reproduction or survival, but are

   

A: due to + 动作名词不够有效；

B: 同上

C: but分句后面没有动词, 会让人产生和because they enhance … but …的歧义

D: correct

E: because of + doing 一定错

 

 

注意：

1、             due to，because of 都是连词because的迷惑选项

2、             but… 的对称有两种都语法说的通，通过补足助动词来区别

上面是find gg的的解释，但是我还是不清楚，为什么C选项but后面要补足 are？ 我觉得句子结构是traits are not...but....，如果加了are就变成了traits are not...but are....，就不对称了啊

顺便问一句，这里的favored怎么理解？？

明天就考试了，期待nn及时解惑！！！many thanks！

C的歧义是

because they enhance reproduction or survival, but simply random by-products
 

小嘴金鱼

是不是说not but后面最好都补出助动词？

难怪说prep题怪。 说C有歧义， D那样根本就不对称。

我对此处也是非常的困惑！ 就是因为觉得不对称所以才把这个“正确答案”排除的

74.-43     (28503-!-item-!-188;#058&003635)

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

(C) because they enhance reproduction or survival, but

(D) because they enhance reproduction or survival, but are   《===如果这也对。。。那么以前的关于not but的对称的认识就都错了！

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

而且，PDF版本的笔记内特别提到说 be not...but be结构就是对的。。。。。 不理解阿！！！！！

怎么不是 be not .....but ....? 或者  not be....but.be ...?其实

D选项读了几遍觉得也是很顺口的。。。。 如果说，c 选项的But有担当介词，表示“除了。。。”的话，的确不能选，但是，这个又和以前认的not .... but的平行对称的知识点有冲突。。请指点啊。。

非常困惑ing.....................

为什么语法题回答的人不多啊。。。

个人觉得楼主的解释挺充分的，有个are在but后面整个句子很清晰。至于
“PDF版本的笔记内特别提到说 be not...but be结构就是对的。。。。。 不理解阿！！！！！怎么不是  not be....but.be ...?”
我看这是系动词的特点，比较：如果是正常的动词，你加not时就一定要加do之类的词，e.g. do not have.....but have....，但系动词前面不会有别的助动词了，所以就只好把系动词放在not前去做平行结构了。个人观点，只供参考。
