Classical demonstration of water
Whether in study or at work, everyone has written a paper, which is of great significance to all educators and the improvement of human understanding as a whole. I believe many friends are very upset about writing papers. The following is a classic argumentative paper on water that I collected for you, for reference only, and I hope it will help you.

Water gives shade in summer and snows in winter; Interprets the waves of rivers and magnificent glaciers.

Water is just a common substance in Qian Qian in nature, but it is extremely extraordinary for life.

Why is water the source of life? The reason is that all living things need water, and water is the basic condition for living things. For example, when scientists study the possibility of life on a planet, the first thing to do is to investigate whether there are traces of water on this planet. Living things are made up of water. Similarly, from our ancient myth, man is the "product" of water. In fact, 70% of the human body is made up of water, so if people are the most intelligent life on earth, then water is the premise for intelligent life to have wisdom. Because of the existence of water, we can sigh the vitality of everything. A world without water is unimaginable. Without water, there would be no origin of species and no world civilization.

Water is selfless. It is dedicated to us all the time, but it never takes it from us. It is not an exaggeration to say that it is our "food and clothing parents". But because of this, we almost never give anything back to the water. When you are in public places, have you ever ignored running water? When you were walking by the river, did you throw rubbish at the river? When you were walking in the mountains, did you turn a blind eye to logging? ..... When you haven't noticed it, you don't know that water will slip away in it and water resources will gradually become scarce. Now, saving water has become a major obstacle that we must face.

How to protect water? First of all, of course, starting from people's consciousness, making people really realize the importance of water saving is a good start for water saving action. The second is to start from the small things in life, and start from the small things in life.

There are many ways to protect water resources. Watering flowers with rice-washing water is one of the methods, which not only saves water, but also adds nutrition to flowers and plants. It's also a good idea to wash the car with car wash water.

With the increase of knowledge, we know more clearly that water is not inexhaustible. Although our earth is a blue "water polo", most areas are still short of water. Therefore, although we live in a water town in the south of the Yangtze River, we can't feel the trouble of water shortage for the time being, but for those who can't enjoy water, get up and protect it immediately! Save water, start with me.

Because there is water, the world is full of vitality; Because there is water, a deep smile can appear on our faces; Because of water, our life is better. But there is very little fresh water in the world! Save water, save water! Save water, start with me! Our earth is a big water polo, 70% is ocean and 30% is land. Look at the map! The map is full of blue oceans, but the water is not drinkable, but salty. There is only one tenth of fresh water left in the world, and a lot of fresh water is "locked" in the towering iceberg. This is not an alarmist! We were born in Jiangnan, a land of plenty, and rivers of all sizes can be seen everywhere. Turn on the tap, it is cool tap water. We drink tap water, wash tap water and waste tap water! A normal family uses about ten tons of tap water a month. What a terrible number!

Neither you nor I will experience the pain of water shortage, but I always see on TV that there are thousands of people in deserts and arid areas, whose faces are like waxed paper, their skin is shriveled, there is no trace of blood, their lips are chapped and dying. Every time I see this picture, my heart seems to be bleeding and those children are short of water. Are we qualified to waste this water of life? Wouldn't it be a pity to continue wasting? How can I live with my conscience? Many slogans of "saving water" are posted in the school, but who will face it squarely and carry it out? number

When I was cleaning that time, I went into the toilet and found that the faucet was turned on to the maximum. "Innocent" water rushed into the dirty sewer. I was reaching out to turn it off when two boys rushed over and said angrily, "What? This water is useful to us! " As he spoke, he picked up some water and sprinkled it on another person. "I just like watching the water flow away. What? " I don't care, doesn't the faucet say "save water"? I screwed up ... a teacher came and everyone avoided, "save water, see?" The teacher refers to instructions. As he spoke, he poured a big cup of tea into the pool, turned on the tap and let the water go, regardless of the rapidity of the water. He washed the cup next to him. After a long time, he turned off the tap and left. I watched silently, very sad. Those wastes are not water, I think they are more like blood and more like fresh life! Alas, no one pays attention to saving water, it's just extravagance and waste.

Perhaps, some people want to recover but don't know how to do it and feel powerless. Here I recommend several methods-at home, we can plug the hole in the pool, wash vegetables in it, wash our hands after washing, and water the flowers after washing. Those who don't know how to save just put the washing water away, leaving only a "grunt" and no chance of "rebirth"; You can also put a few bottles of mineral water in the toilet tank ... don't you save water, too? If so, wouldn't it be a win-win situation? Why not do it? In fact, saving water is not difficult. As long as you do it with your heart, the water will be "regenerated" again and again, and then we will be "water-saving little guards" with boundless merits! Finally, let's shout the slogan: "Save water, start with me!" " "
