We found the water so dirty that we could hardly catch fish in it.　　A lot of factories along the river always poured their waste water and rubbish straight into the river which made the river water polluted. In this way most of the fish in the river were killed.　　If the river water all over the country is polluted like this， no living things will exist in the water. As we all know， environmental pollution does great harm to living things and human beings. Now more and more people have come to realize how serious this problem is. Our government is doing her best to take measures to fight against pollution. We expect that the water in every river will be made cleaner and cleaner before long.
