问题 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.
选项 A、extending
B、extends
C、extended
D、it extended
E、it extending
答案 A
解析 首先排除D、E，因为在逗号之后的内容都对the living organism进行修饰，it extended(extending)找不到与其相平行的部分，而A、B、C都可以找到与其相平行的部分；A、C与spawned相平行，共同修饰tentacles；而B则是与is并列，共同修饰fungus。本题解题关键在于回到句中从逻辑上理解：究竟划线部分应修饰哪个词。从逻辑上分析，应修饰tentacles，应该是“触须延伸”而不是“真菌延伸”，后者是讲不通的，而延伸肯定是一个主动动作。因此C用过去分词错，应用A：extending。
