15．The plan had been made to create a beautiful nature park with a large man-made lake on the outer parts of the city of Zhengzhou，the capital of Henan Province．However，thanks to a terrible trick played by nature，what the officials have ended up with，is a natural sandy mess!
The government wanted to create a beautiful place where people of this busy industrial city could come to relax．But things did not quite turn out that way---shortly after digging up thousands of tons of sand，the underground water dried up．As a result，the dry sand has changed into a Sahara-like desert．While official reports show that the sand is piled up to 10meters high，some people say that it is ten times more or about a 100-feet high in certain areas．
If that is not bad enough，the sand hills that now spread across an area the size of four football fields，have influenced the environment．What's worse is that on windy days，the dry sand moves into the city center，making it almost impossible to drive and forcing people to wear face masks and protective eyewear to prevent the sand from getting into their eyes，nose，and mouth．
In an act of trying to keep the sand and provide the illusion（幻想） of green fields，the officials have even tried covering it with a green plastic netting．However，that has not done much to improve the terrible situation!
As you can imagine，many of Zhengzhou's residents are upset by the disaster．They think that desert wasteland that looks nothing like the green landscape they were promised，has resulted in polluting their pleasant city environment．Some think it is even stopping businessmen from coming to the city．

分析 郑州市原计划建立一个有大型人工湖的美丽的自然公园，但挖出成千上万吨的沙子后不久，地下水源枯竭，干沙犹如撒哈拉沙漠，风吹干沙，漫天飞扬，破坏了当地植被与环境，给人们的生活造成了很大的影响．
解答 21．B 推理判断题．根据第一段的what the officials have ended up with，is anatural sandy mess可知，最后政府的结局是一个自然的沙堆，所以作者可能认为建人工湖是不可能的，故选B．
22．D 细节理解题．根据第二段的the underground water dried up，As aresult，the dry sand has changed into a Sahara-like desert．可知，干沙变成了撒哈拉样的沙漠是因为地下水干涸了，所以没有地下水是主要原因，故选D．
23．C 细节理解题．根据第三段的making it almost impossible to drive and forcingpeople to wear face masks and protective eyewear to prevent the sand fromgetting into their eyes，nose，and mouth．可知，使人们几乎不可能开车并强迫人们戴上口罩和保护眼镜，以防止沙子进入他们的眼睛，鼻子和嘴．所以干沙造成了空气污染，故选C．
24．A 推理判断题．根据最后一段的Theythink that desert wasteland that looks nothing like the green landscape theywere promised，has resulted in polluting their pleasant city environment．Somethink it is even stopping businessmen from coming to the city．可知，人工湖污染了城市环境，一些人认为它甚至阻止了商人来到这个城市．所以郑州市民认为人工湖是可怕的，故选A．
