1.The traffic problem we are looking forward to seeing _____ should have attracted the local government’s attention.
A. solving B. solve
C. to solve D. solved
解析：选D。本题主要考查学生分析句子的成分和掌握结构的能力。we are looking forward to seeing是定语从句修饰先行词the traffic problem, 同时充当seeing的宾语，而用solved作宾补，表示被动，即see the traffic problem solved。
