The role of water 水的作用

Water is very important to us. If you don’t have water for three days, you will die. We can use water for flowers, swimming, washing and many different things. We use it to cook, make electricity, and put out fires and so on. We use millions of liters of water every day.

Do you know how does the water come to your home? It travels through water pipes. Some are long and wide but some are short and narrow. Then the water travels through the water pipes to the reservoirs. Then it travels through the water pipes to the river and to the special factories that purify the water. When the water is purified, we can drink it. Please don’t leave garbage in the water on which we line, and keep the water clean.水对我们很重要。如果你三天没有水，你会死的。我们可以用水浇花，游泳，洗涤和许多不同的东西。我们用它做饭，发电，和扑灭火灾等。我们每天都使用数百万公升的水。你知道水是如何来到您的家吗？它穿过水管。有些是长和宽但有些短而窄。然后水通过水管的水库。然后穿过水管的河流和特别的工厂的净化水。当水净化后，我们就可以喝。请不要把垃圾丢进水里，并保持水的干净。
