42.水

　　Water is veryimportant to us. If you don’t have water for threedays, you will die. We can use water for flowers, swimming, washing and manydifferent things. We use it to cook, make electricity, 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? Ittravels through water pipes. Some are long and wide but some are short andnarrow. Then the water travels through the water pipes to the reservoirs. Thenit travels through the water pipes to the river and to the special factories(we call water plants) that purify the water. When the water is purified, wecan drink it. Please don’t leave garbage in the water on whichwe 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。我们可以用水花，游泳，洗涤和许多不同的东西。我们用它来做饭，发电，灭火等等。我们每天使用数百万公升的水。

你知道水是怎么来你家的吗?它通过水管传播。有些是长和宽，但有些是短和窄。然后水通过水管到达水库。然后它通过水管到河流和特殊的工厂(我们称之为水植物)净化水。当水净化后，我们就可以喝了。请不要把垃圾留在我们的水，并保持水的清洁。
