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.
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 官方解释说是B与is的平行会有歧义。。。 看不出来。。。 求解释
"...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." "that is an interwoven filigree..."和"is extending"平行,如果是"extends"就不平行了。
OG的解释是:Extends is a present tense verb, not the participle needed for parallel structure; the ostensible parallel between extends and the distant verb is is superficial and would result in an awkward and unclear sentence. (Extends是一般现在时,不是平行结构需要的分词;extends和is只是表面上的平行,会导致整个句子有歧义。)
所以整个句子的结构就要分层切开: 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)].
简化的话就是 [P] and [P(p and p)], (而不是从句that后的[P(p and p)] and [P])。从而判断动词原形extend要和spawn搭配。这时候只有两个选择:extended或者extending。由主句living看出该货还活着,所以是extending.
我觉得这个句子分层切开应该是A giant fungus that is an inter woven filigree of 【mushrooms and rootlike tentacles (spawned by a single fertlized spore some 10,000 years ago) and (extending for more than 30 acres in the soil of a Michigan forest)】
如果extend是修饰tentacle的选择A倒是不难理解,可是OG的解释是“The giant fungus is described as an interwoven filigree spawned... some 10,000 years ago and extending for more than 30 acres”, 也就是说这个extend是修饰filigree的啊
