问题补充：
The worse working conditions we are looking forward to must have attracted the local government’s attention.
A. see improved
B. seeing improved
C. see improving
D. seeing to improve
答案：
A. see improved
(答案→)B. seeing improved
C. see improving
D. seeing to improve
解析：考查固定搭配和定语从句。we are looking forward to 是定语从句，先行词是The worse working conditions，把先行词代入定从是we are looking forward tothe worse working conditions. looking forward to中，to后用ing形式，所以用seeing。而see+宾语+宾补结构中，宾语the worse working conditions和宾补improve之间是动宾关系，所以用improved。从而选B。
