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
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。
2. — He ought to have been warned of the danger.
— ______, but he just wouldn’t listen to me.
A. So ought he B. So he was
C. So was he D. So he had
选B。ought to have been warned of表示“本应该被告诫有危险”，是对过去动作的推测，因此回答也应该用过去时。A的构成形式不对。而So he was必须与第一句谓语动词have been一致。
