0G11-39请教

39.      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.

B        extends

C      extended

D     it extended

E     is extending

大家说说选择哪个? 答案是A,我选择的是c

主动和被动的区别。

现在分词表主动

过去分词表被动

我也选择了c答案。

主要是考虑到与spawned一致，但是看了解释以后，从句子的含义来说，选择a是正确的，因为extending表示的是现在的状态。
