Dear Editor,
As we know environment is very important for us.But yesterday,I saw a factory in our city polluting one of our hometown's river by its dirty water.The grass and flower were all died because of the dirty water.I hope that you can report it in your newspaper,Time,to stop the factory from polluting our river
That's all
Yours truly

写得应该还可以吧?我也是高二的而已!水平差不多这样也符合你的要求吧?写得太好的未免太不符合实际了
