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. Water is essential to living things. For instance, if there is no enough water in a human body, a person may feel uncomfortable or get sick easily. To make matters worse, one may die of thirst. Similarly, plants may wither or die for lack of water. It is apparent that all living things need water to keep alive. Judging from the importance of water, we should know how to conserve water. The first thing is to stop polluting water because what we really need is clean water. At the same time, be sure to turn off the faucet immediately after using water. And we should make efficient use of water to avoid wasting it. One way is to recycle as much water as possible. To sum up, we should economize on water so as to maintain the abundance of water, which is an indispensable element of life. 水是我们非常重要。

如果您没有三天的水，你会死。我们可以用鲜花，游泳，洗涤和许多不同的东西水。我们用它来烹调，使电力，扑灭火灾等。我们使用数百万公升的水，每天。 你知道如何到你家的水？它穿过水管。有些长，宽，但有些短而窄。然后穿过水供水管网的水库。然后穿过水管的河流和特别的工厂（我们称之为水植物）的净化水。当水的净化，我们可以喝。

请不要留下垃圾的水是我们的行，保持水的清洁。水是生活的事情。举例来说，如果没有在人体足够的水，一个人可能感到不舒服或不易生病。更糟的是，人们可以渴死。同样，植物可能会枯萎或缺水死亡。很明显，所有的生物需要水来维持。 从水的重要性来看，我们应该知道如何节约用水。首先是停止污染水，因为我们真正需要的是清洁的水。

同时，一定要关闭水龙头后，立即用水。我们应该使水的有效利用，避免浪费它。一种方法是回收尽可能多的水。概括地说，我们要节约用水，以保持充足的水资源，这是生活不可缺少的元素。
