水是我們的生命之源，是我們生活中不可缺少的的東西，沒有水，恐怕我們真的要迎來世界末日了。你知道水是怎么到你家的嗎?你知道水資源的現狀了嗎?我們一起去了解一下水吧。

　　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, 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 (we call water plants) 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.
