大学英语作文:Keeping Water Sources Clean 保持水源清洁

Who is willing to drink the polluted water? It can cause us to be ill and even to die. We cant wait for a moment to protect our water sources. The water we use comes from oceans, lakes, rivers or streams. But many of these water sources are getting seriously polluted. Towns and cities are pouring dust into the water. Many people are throwing all kinds of dirty things into the water. Factories are pouring waste material into the water. Therefore, water sources have become so badly polluted that some of the water is unfit to drink or to use. Now it is high time that we should do something to protect our water environment from being polluted.

被污染的水会使人生病甚至死亡，有谁愿意喝这样的水呢?我们要保护水源是刻不容缓的。我们用的水来自海洋、湖泊、河流或小溪，但有很多这些水源正受到严重的污染。城镇和都市都把大量的尘埃排进水中，很多人正把各种各样的脏物投进水中，工厂正把废物排进水中。因此，水源已经被严重污染到其中一些不适合再饮用了。现在到了该采取措施保护水环境使其免受污染的时候了。
