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.

水對我們很重要。如果你三天沒有水，你會死的。我們可以用水澆花，游泳，洗滌和許多不同的東西。我們用它做飯，發(fā)電，和撲滅火災(zāi)等。我們每天都使用數(shù)百萬公升的水。

你知道水是如何來到您的家嗎?它穿過水管。有些是長和寬但有些短而窄。然后水通過水管的水庫。然后穿過水管的河流和特別的工廠的凈化水。當(dāng)水凈化后，我們就可以喝。請不要把垃圾丟進水里，并保持水的干凈。
