问题补充:
Not easy as the problem of pollution is, no one should just stop trying.
A. to solve
B. to be solve
C. solving
D. being solved
答案:
(答案→)A. to solve
B. to be solve
C. solving
D. being solved
解析:考查固定结构。Not easy as the problem of pollution is,是as引导的让步状语从句,是一个倒装句,正常语序应是as the problem of pollution is not easy结构,考查做某事不容易结构,即be not easy to do 结构,所以选A。
