有關節約用水的英文演講稿範文 篇1
In our daily life, water has many useful ways. We can use water to wash our faces and brush our teeth. Farmers water plants with it, while firemen use it to put out fire. And the cooks cook food, wash the bowls and plates with it. If there were no water, people, plants and animals would die, and the earth would become a dry well.
If we don t want this kind of thing to happen, we must save water from We can begin with doing small things. For example, after we wash clothes, we can use the used water to clean the rooms, windows or floors. Finally we can wash the restroom with it. When we dont use water, we must turn off the tap tightly. If everyone can save water, the environment will be better and better.

The world is not only hungry,but also thirsty for water. This may seem strange to you, since nearly 75 % of the earths surface is covered with water. But about 97% of this huge amount is sea water, or salt water. Man can only drink and use the other 3% . the fresh water that comes from rivers, lakes,underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.
However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. But our need for water is increasing rapidly-- almost day by day. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one small exampie of how necessary water is to industry. Did you know that to produce a single ton of steel, it takes about 91, 000 liters of water?
We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on a small scale. For us, the systems are as important as the spacecraft.

各位老師，同學們：
大家好！
生活中水是不可缺少的，水能洗手、洗臉、洗頭、解渴、養魚蝦、澆花……是啊，水對我們來說，是如此重要！
水是生命之源。哪兒有水，哪兒就有生命。水分約占人體體重的65％。一個人如果缺水5％，就會意識不清，甚至出現幻覺。
水是工業的血液。製造一噸鋼，約用25噸水。製造一噸紙，約用450噸水。
食品加工離不了水，醬油、醋、啤酒等，都是水的化身。
然而，我國的水資源並不豐富。在雲南、甘肅等一些缺水地區，能讓孩子喝上一口乾淨的水，洗個澡，都是眾多母親的奢望。一個老農用一根粗繩把一個七八歲的孩子滑到井底，為的是一瓢一瓢舀上半桶略帶泥沙的飲用水【演講稿】節約用水。而看看我們身邊的一些人呢，嘩嘩的流水，為的是洗一塊毛巾；炎熱的夏天，當你舒舒服服衝著涼水澡時，你所用的水是缺水地區的人半個月的用水量；當你粗心，沒有把水龍頭擰緊時，它一個晚上流失的水，相當於非洲缺水地區一個居民一星期的飲水量……
