Scientists have recently discovered what could be the largest and oldest living organism on Earth, a giant fungus that is a interwoven filigree of mushrooms and rootlike tentacles spawned by a single fertilized sport 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上解释说，A正确是因为extending refers to something that continues into the present. 那为什么不用has extending啊？作者: IMARCUS 时间: 2011-1-10 21:23
has extending?是啥？has extended?没这选项啊。。作者: swlfxer 时间: 2011-1-11 06:41
两修饰成分并列：原句可以还原：
...tentacles (that is) spawned by a single fertilized sport some 10,000 years ago and (that is) extending for more than 30 acres in the soil of a Michigan forest.
ps.看到and就想平行。但要注意是和什么平行。
gmat中有很多分词直接做修饰的成分出现，例如这题。一开始很容易搞不清这是什么句子成分，多做多总结就好了。
