问题 The editors said they must report to the world how Beijing has______pollution and improved the quality of the environment.

选项 A、cut up
B、cut off
C、cut down
D、cut out

答案 C

解析经分析可知空格处的意思是：减少污染，改善环境质量。只有cut down意为“砍倒，削减”符合句意，cut down pollution的意思是“减少污染"，因此本题的正确答案为C。cut up：“抨击，歼灭”，cut off：“切断，断绝”，cut out：“切掉，取代"，明显都不符合句意。
