74. (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

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

2) but的用法: but做介词,表示除了… 例:No one has read it but the students. 或者用在词组not…but…举行中,作连词表示不是,而是的意思, 例: The plan caused not prosperity but ruin.

这道题在C 和 D 中选，因为紧守
            not…but…的并列形式，很容易就选了C。解释C说：but可能作为介词,产生because they enhance reproduction or survival, but simply random by-products的歧意 解释 D 说：but are表明了but在这里只能作为连词,构成be not… but (be)…的平行结构

共勉之。

这个题每次做我都会选C，真是没治了........
