OG12 SC42

42. 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

这是道被很多人讨论过的老题，答案是A，我看下来最general的分析是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. 普遍认为 a giant fungus that is spawned and extending 平行，我的问题是如果是按照这个逻辑分析的话，an interwoven filigree of mushrooms and rootlike tentacles在这里作何成分？？ 谢谢！

我也觉得是分词和修饰主语的被动、主动关系。不过OG12的解释是说spawn是发生与10000年前因此是过去分词，而fugus现在仍然extend所以是现在分词。对这个解释不大理解，难道如果extend也发生在过去就用过去分词了吗？求指教

有点明白了，也就是说正确的结构式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）对吧 谢谢

an interwoven filigree of mushrooms and rootlike tentacles就是这个giant fungus。spawned & extending是修饰an interwoven filigreen，或者认为是修饰a giant fungus 。

spawn & extending是修饰an interwoven filigreen of mushrooms and rootlike tentacles的，spawn和它是被动关系，extend和它是主动关系，都是分词，所以平衡。
另外an interwoven...tentacle就是a giant fungus，说的是同一个东西。a giant fungus在这做同位语，修饰前面整句话。
如果不对，请指正
