Spring is the best season of a year. The ing so dirty that nothing can live in them. The rivers are giving off a terrible smell.
We make an urgent appeal that measures should be taken to cope with the situation. Our government should build various facilities such as sewage treatment plant and encourage scientists to work out more and better ways to reduce water pollution.
Water is the source of our lives. It is very important to protect the water.
春天是一年中最好的季节。天气变得越来越暖和，我和同学进行了环城一日游，所到之处景色宜人。但当我们看到流过城区的河流时，我感到很惋惜，想了很多。
随着现代工农业的发展，越来越多的污水正被排进河里，河水被严重污染。水变得如此肮脏，以至于生物不能在里面生存。河水发出难闻的气味。
我们急切呼吁应该采取措施改变这种状况。政府应当兴建各种设施，例如污水处理厂，并且鼓励科学家们想出更多更好的办法以减少水污染。
水是生命之源。保护水资源十分重要。
