OG 210大平行和小平行

mathfin9

刚才搜索了一下，看到以前讨论的几篇

但是还是想请教一下

怎么判断这个extend是和spawn平行，是小平行，

而不是和that is 中的is 平行

这个题目，我觉得非常专业化，对于非这个专业的人来说，那些名词几乎都不明白，这个题目是不是就无从得解呢

210. 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
Choice A, the best answer, preserves grammatical parallelism while allowing for logical expression of temporal relationships; A employs the parallel participial phrases spawned... and extending ... to modify filigree. Other choices present different grammatical constructions that are not participial modifiers and thus not parallel to spawned: extends in B is a present-tense verb; it extended in D begins a new clause; and is extending in E ungrammatically introduces a new predicate. In C, extended is nonparallel if it is assumed to be a past tense verb form; if it is assumed to be a past participle, it illogically states, as does D, that the filigree extended only in the past.

首先看A，A的extending作为分词结构可以和spawned分词结构平行，充当形容词，从意思上也可以理解，所以A可行；

其实，A选项无论对错，对我们选择答案都有很大的作用，A一般情况下(除非明显错误)决定了大结构；

如果extends要和is动词平行，至少extends前要补出that，以明确平行关系。

抓抓sandra

同意楼上说的extends要加上that以表示大平行的说法~
