【结构:XXX,a A that is a B ①[of....] ②[V-ed.....]and[V-ing......]---->同位语从句;两个modifier修饰B:第二个modifier中包含一组分词小并列------------------------------------------------------------------※※※具体来讲,是: a giant fungus that is an interwoven filigree ①of mushrooms and rootlike tentacles ②【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.
spawned 是过去分词修饰(mushrooms & rootlike tentacles)所以后面应该也是一个分词修饰(mushrooms & rootlike tentacles)
tentacle主动延伸
and 并列spawned和extending并列 作状语。spawned by是表被动,extending主动ing
an interwoven filigree of... spawned by ...and extending for ...
an interwoven filigree of... spawned by ...and extending for ...
extending和spawned一样用来修饰tentacles
an interwoven filigree of mushrooms and rootlike tentacles "spawned" and "extending" both participle
a giant fungus that is .... and that extends-- that extends = extending
Because the "scientists have recently discovered" that it "is" - that is, this is taking place in the present tense. If it could be the largest living organism, now, then it should still be extending.
