保持水源清潔 Keeping Water Sources Clean

Who is willing to drink the polluted water? It can cause us to be ill and even to die. We can't 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.

被污染的水會使人生病甚至死亡，有誰願意喝這樣的水呢?我們要保護水源是刻不容緩的。我們用的水來自海洋、湖泊、河流或小溪，但有很多這些水源正受到嚴重的污染。城鎮和都市都把大量的塵埃排進水中，很多人正把各種各樣的髒物投進水中，工廠正把廢物排進水中。因此，水源已經被嚴重污染到其中一些不適合再飲用了。現在到了該採取措施保護水環境使其免受污染的時候了。
