OG143请教

dormousedzc

OG说E   While a development may appear to parallel a branch,the logic of the sentence is contradicted by the meaning of this usage,

是什么意思啊,这种用法造成的矛盾之处在哪里呀???

谢谢指教

这道题的主考点在parallelism，看出来了就能选出答案。但是independent from和of 让人非常郁闷。我是这样理解的：朗文当代上和M-W上都没有把independent from作为固定搭配列出来，我们也就不要把它当成固定搭配看。如果分开看很容易理解developed independently from "Y" 就是从“Y”独立发展出来的意思。而developed independently of"Y"是从独立于“Y”的起源发展而来的意思。OG10的解释相对详细些。In C, the expression a type whose development was independent of a common ancestor states the opposite of the original point_that the type of mammal mentioned was thought to have developed independently of the main stem of mammalian evolution, but still to have descended from a common ancestor.
