B.       hard enough to make burrowing difficult or soft enough as to cause

C.      so hard as to make burrowing difficult or soft enough so it causes

D.      as hard as to make burrowing difficult or as soft as to cause

选A，我选了D

请问哪里错了？

谢谢~~

给自己顶顶~~！！

后面的with a third of them 有没有错？？

错了 独立主格结构中的with是不可以随便乱加的 加了with 就直接修饰forest了

41 A it指代不明

D里面 两个as as中的前面一个改为so 我觉得才是最好的答案

so hard as to make burrowing difficult or so soft as to cause

那是不是因为没有as...as to的结构的原因？？
