Water is very important to us. If you don't have e 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.
你知道水是如何来到您的家吗？它穿越水管。有些是长而宽的，但有些是短而细的。然后通过水管到达水库。然后通过河流和专门用来净化水的工厂。当水净化后，我们可以喝它了。请不要丢垃圾到水中，因为水是我们的生命线，我们要保持水的清洁。
