Beneath the soil of the Malheur
                National Forest in eastern Oregon, a fungus has for centuries been slowly weaving its way through the roots of trees, to become the largest living single organism known to humans.

(A) has for centuries been slowly weaving its way through the roots of trees, to become

(B) has slowly woven its way through the roots of trees for centuries, and so becoming

(C) that has been slowly weaving its way through the roots of trees for centuries has become

(D) that has for centuries slowly woven its way through the roots of trees and has become

(E) that, having slowly woven its way through the roots of trees for centuries, to become

答案是D

选不出答案。

如果选D的话，句子岂不是残缺的？

从语法上讲，我感觉C最想正确答案。但是句子的意思就变得很奇怪。因为beneath引导的介词短语就要和has become搭配。Beneath the soil of the Malheur
    National Forest in eastern Oregon, a fungus has become the largest living single organism known to humans. 读起来怪怪的，当然很有可能是我的英文不够好。

A. to become前面的逗号造成句子结构混乱 错

B. and so becoming 逻辑意思不错，但是没有平行对象 错

D. has done... and has done... 平行 但是逻辑意思错

E. that....to become 主句缺少谓语 错

C 的结构：“状语，a fungus（主语）＋that定语从句修饰＋ has become（谓语）...” 句子完整 逻辑意思也正确 看不出有什么毛病了
