prep 43

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

C:many biological traits are not .....but....

说不出道理

同错这道题，选的C

在地心等NN。。。

我看出来了。。我们经常错一样的题。。。

反正你问的我都错了。。。。

你顺面帮我看看我贴得另外两个问题嘛：）

偶也错掉这个题了，看一下如下解释有没有帮助，偶从but的词性上下手。

but可以作连词，也可作介词。

在这个句子里是用作连词的，not…, but…. 。但是C中的but可被看作介词（except的意思），产生歧义（即：enhance reproduction or survival, but by-products of..）。

加上are后，说明but后跟句子，一定是not …but…中的连词。

ls说的有道理，不用可以强调形式的对等，BUT就是连词就好了
