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(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可是不应该是选C,are not...but的结构吗?为什么是D中are not...but are的结构呢?
这是笔记的解释..
考点: 逻辑表达(Logical Predication) 平行对称(Parallelism)
1) 介词短语
n account of, because of, despite (in despite of), as a result of, due to之后只跟简单的
名词短语。若其后面跟的是动名词或名词所有格+动名词短语(sb’s doing),或名词短语之后用一复杂的
现在分词来修饰时或后面跟动词的抽象名词形式,应改为与其相同意义的连词because, although等引
导的从句形式。
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.
(A) due to +动词的抽象名词形式,表达不够有效;not…but…连接的结构不平行。
(B) due to +动词的抽象名词形式,表达不够有效; they多余, 破坏了 sth/sb be not… but (be)…的结构
(C) but可能作为介词,产生because they enhance reproduction or survival, but simply random
by-products的歧意
(D) 正确,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
(E) because of +动名词形式,表达不够有效
不太懂....求帮忙,感激不尽~
