OG11th--39

Scientists have recently discovered what could be the largest and oldest living organism on Earth, a giant fungus that is an interwoven filigree of mushrooms and rootlike tentacles spawned by a single fertilized spore some 10,000 years ago and extending for more than 30 acres in the soil of a Michigan forest.

(A) extending

(B) extends

(C) extended

(D) it extended

(E) is extending

        请问下:这道题目是从含义上的对称可以突破形式上的对称来思考,即:fungus在10000年前是通过X来产卵的,并且在MF一直延伸超过30英亩;

                   还是从分词和分词对称,但是未必过去分词与过去分词,现在分词与现在分词对称,关键是看动作是主语的发出者还是承受者这个角度思考? fungus与spawned 被动关系,但与extending是主动关系

        恳请NN指点下,谢谢!

spawned / extending是修饰filigree

Mayanist:也就是从第二个角度理解,更加合理,是吗?

整理下主干就清楚了

Scientists ( 主语）have recently discovered （ 谓语）what could be the largest and oldest living organism （ 宾语）on Earth, a giant fungus（同位语修饰宾语） that is an interwoven filigree of mushrooms and rootlike tentacles spawned by a single fertilized spore some 10,000 years ago and extending for more than 30 acres in the soil of a Michigan forest.

<a giant fungus（ that is an interwoven filigree spawned by ）... and  extending..., > 整体上仅仅是个名词同位，要修饰宾语。 a giant fungus 又有两个修饰语，extending and that 从句 。

我认为extending是和spawn对应的，只不过一个主动，一个被动。

大家觉得spawn到底是修饰什么？filigree？

谢谢大家的帮助

分词对称并不排除现在分词与过去分词的对称，关键是看动作的发出者，还是承受者
