Q41:

At the turn of the twentieth century, forest covering as much as 90 percent of Thailand and accommodating as many as 300,000 elephants, a third of them

 domesticated and performing various essential tasks.

正确答案为D

D. covered as much as 90 percent of Thailand and accommodated as many as 300,000 elephants, a third of them

E. covered as much as 90 percent of Thailand and accommodating as many as 300,000 elephants, with a third of them

请问E为何不正确，不能理解为with 引导的独立主格结构吗？

with 引导的独立主格与不用with 引导的独立主格就够有什么不同吗?

多谢！

首先很是感谢。但是还收有些疑惑。看到PREP 破译中和白用语法中都有说过：独立主格结构共有3种：

引用prep破译中的：

Visitors to the park have often looked into the leafy canopy and seen monkeys sleeping on the branches, with arms and legs hanging like socks on a clothesline.   

with 在这儿是有实际意义和功能的，with 的使用恰好表达了某种途径或手段，意思传达非常清晰
