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.
原题: 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 OG解释: A Correct. Th is sentence has the participles spawned and extending in a correct parallel construction. Spawned refers to something that happened in the past, while extending refers to something that continues into the present. 不理解past/present的解释啊,难道不是被动和主动的问题么??
spawned指的是生长蔓延的意思吧~就是说some 10,000 years ago 的时候长的(注意ago,所以用过去时,in the past)~~鉴于the largest and oldest living organism on Earth~说明现在还在扩展中即extend~用extending表示到现在还在长~(continues into the present )~~spawn和extend都表示主动~只不过spawn发生在过去~
原句是说科学家最近发现了一个东西, 是世界上最大,最古老的活体器官, a giant fungus...是个同位语吧? that 引导定语从句修饰 fungus, 定语从句就说这个东西由2部分构成mushrooms and rootlike tentacles, 接着就是用spawned…and extending…的平行结构作后置定语修饰rootlike tentacles
