Last Sunday my father and I went fishing along a river. 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.
上个星期日我和爸爸一起去钓鱼。我们发现水太脏了，我们几乎不能在它的鱼。
沿着这条河的许多工厂总是把废水和垃圾倒进河里，使河水受到污染。这样，河里的大部分鱼都被杀死了。
如果这个国家的河水都被污染了，水里就不存在生物。我们都知道，环境污染对生物和人类都有很大的危害。现在越来越多的人开始意识到这个问题有多严重。我国政府正在尽最大努力采取措施打击污染。我们期望在每一条河流中的水将在长时间内变得更清洁，更清洁。
