Excellent composition on water saving 1 Beautiful scenery, birds and flowers, good weather and good harvest of crops are the beautiful scenery that human beings pursue and yearn for, and also the fruits of human labor creation and careful care. Water is constantly flowing, which makes the world full of vitality and vigor in human body, farmland and factories. When we are wandering in the embrace of nature, what we are actually facing is the power given to us by water. Seventy percent of the human body is water. Water-gives us green, life and hope. Why don't we appreciate it, cherish it and care for it?
I wonder if students think that water is "inexhaustible"? Although our earth is a blue water polo, most of it is covered with water, but most of it is salt water, so it can't be directly drunk, and there is not much fresh water that can really be used. A European uses about 135 liter of water every day, while in developing countries, residents usually only use 10 liter of water every day. China is a developing country, and there are two major problems in China's "water": one is the shortage of water resources, and the other is the serious water pollution. The per capita freshwater resources are only 1/4 of the world average, ranking 1 10 in the world, and it is one of the countries with the poorest per capita water resources in the world.
There is a public service advertisement that says well: "If human beings don't save water, the last drop of water on the earth will be human tears." This is by no means alarmist. Today, more than 10 billion people in the world cannot get enough clean water; About 5 million people die every year from drinking polluted water. Students, in the face of this shocking figure, we have an obligation to save water.
"Saving water" is not lip service. There are many ways to do it in our life:
At school, turn off the tap after washing your hands to prevent dripping; After the hot weather in physical education class, don't turn on the tap and splash water on your head and face. There is water everywhere outside the sink. You shouldn't take a big bottle of pure water and throw it away after a few sips; Students who wash dishes and chopsticks should not take this opportunity to play water games.
At home, wash dishes and chopsticks together; Turn off the tap between washing your face and brushing your teeth; Don't leave the shower head on all the time when taking a bath, so as not to cause unnecessary waste; One thing can be used for multiple purposes, the water for washing clothes can wipe the floor, the water for washing the floor can flush the toilet, the water for washing rice can water the flowers and so on. It is best to wash a small amount of clothes by hand to avoid consuming a lot of water by washing with a washing machine; Use less detergent and cleaning agent when washing to reduce water pollution.
Teachers and students, let's ask ourselves gently in our hearts: "Did I save water today?"
Water is the source of life for all living things on earth. People need water, plants need water, and animals need water. What if there is no water in the world? Animals will appear listless; Plants will wither; The last tear of mankind will be the last drop of water.
Water is a valuable resource. According to statistics, the fresh water on the earth only accounts for 2.7% of the total water, while the fresh water available for human use only accounts for 25% of all fresh water. Human activities not only consume a lot of resources, but also cause water pollution, leading to water crisis. The crisis of water resources is not only related to the sustainable development of mankind, but also to the survival of mankind. Students, nature has sounded the alarm for us!
In the face of these bleak data, isn't our heart touched at all? Yes, that's right! Each of us is still wantonly destroying it. Generally speaking, on the one hand, China's water supply is quite tight, and the water shortage situation is becoming increasingly severe; On the other hand, the utilization rate of water resources is low and the waste is amazing.
According to statistics, China's agricultural water consumption accounts for more than 60% of the total water consumption, but the effectively used water only accounts for about 1/3 of the total agricultural irrigation water consumption; The water consumption per 10,000 yuan of industrial output value is also twice that of developed countries. The extensive use of industrial wastewater, urban sewage, pesticides and fertilizers in agriculture has increased the pollution of water resources. Serious water pollution also reduces the available value of water resources and further aggravates the water shortage in China. About half of the country's production and domestic wastewater is discharged into rivers and lakes without treatment, which leads to the deterioration of water environment in most parts of the country and makes the already scarce water resources more tense.
Saving water and protecting water resources is one of the important ways to solve the problem of water shortage in China. In agriculture, it is necessary to change irrigation methods, abandon flood irrigation and gravity irrigation, and popularize sprinkler irrigation and drip irrigation technology; Change crop varieties and plant crops with drought tolerance and low water consumption; Reduce the use of pesticides and fertilizers. In industry, industrial water is reused and recycled; Reduce production water consumption and improve utilization efficiency; Water treatment, discharge up to standard. At home, water has many uses; Promote water-saving appliances; Use less detergents and cleaning agents.
The water-saving sign I see is made of water drops, human hands and the deformation of the earth. The green circle represents the earth, and the blank part is like holding a drop of water in one hand. Hand is a variant of the Chinese phonetic alphabet J and S, which means saving water, indicating that saving water requires public participation, encouraging people to start from me and saving every drop of water; The hand is like a winding river, symbolizing that water drops converge into a river.
Let's act now, and don't let the last drop of water on the earth turn into our tears!
Water is a familiar substance around us.
March 22nd is the 9th World Water Day, and March 22nd-28th is the 24th China Water Week.
It is said that when the earth was just formed in the universe (from soil gasification to virtual reality), volcanoes erupted everywhere, bringing the water inside the earth to the ground; The landing of extraterrestrial meteorites also brought a lot of water from other planets. After hundreds of millions of years of evolution, the earth has become a blue planet, with water covering more than 70%.
However, in this huge "reservoir", more than 97% of the water is occupied by the salt in the soil, which is salty and bitter seawater. Only 2.8% of the remaining water is drinkable, and most of it is confined in glaciers in the Antarctic and Arctic, so that only 1% of the fresh water resources exist in rivers, lakes and underground. I can't help but feel sad and surprised: the Yellow River has been cut off, Settsadas Waterfall has disappeared forever, Huangguoshu Waterfall has lost weight overnight, and the Gulf of Mexico is mixed with water and oil-how many drops of water on the earth can moisten our withered mouthparts? I think the mother river has raised all the children in the world; Liang Shanshui spans 800 miles in Fiona Fang; Seeing that there is no water available in thousands of cities today, it is feasible to walk on the north and south banks of the Yangtze River! Where can we see your face today when the waves are rolling and the rivers are surging? I saw a few remnants, tears like broken beads: "I didn't see the elegance of that year"!
Think about how many dull but painful scenes there are in real life: water is beating here, and dripping water is hard to find in the distance; But at the faucet, the waves are rough and no one makes it close; Here is a drop of water, but there is no disdain to enter the throat; Although I feel sad before looking at the dry well, I still let the clear water flow forever.
The era of inexhaustible water has long passed, and the era of cherishing, protecting and utilizing water resources has arrived. We should develop the habit of saving water from childhood: the water for washing vegetables and rice can be used to wash dishes and mop the floor, and the oil removal effect is very good; The water after washing clothes can be used to flush the toilet; The water from fish farming can be used to water flowers and effectively promote plant growth; Mixing cigarette butts and other things in unused dirty water can kill some pests; Face washing water can be used as foot washing water; Conditional home to install some water-saving appliances; You can also use special large barrels of sewage to flush the toilet; Don't try to flush the garbage with the toilet and waste water-water is the source of life. Of the eight planets in the solar system, only the earth has enough liquid water for life to multiply. If all this water is used up, how can we talk about the word "survival"
If we act now, the last drop of water on the earth will no longer be the tears of human regret.
Water is one of the best drinks for people. People need water, plants need water, and animals need water. What if there is no water in the world? Animals will appear listless; Plants will wither; The last tear of mankind will be the last drop of water. Please save water resources.
There is a story: in a remote place, there lived a family, in which lived an old man in his fifties. His only source of water is a small pool on the mountain three or four kilometers away from home. So he used water sparingly, and set off from home at three or four in the morning to catch three or four kilometers to get water. He won't get home until eight or nine in the morning. One morning, he only used a spoonful of water to cook, wash his face and flush the toilet. At noon, it used less than half a bucket of water; In the evening, he bathes in the pool water heated by the sun in the morning. This is the water he uses for a day, just two small buckets of water.
In our family, there are also many examples of saving water: after I wash my face with my parents in the morning, I will save water, and we can use it to flush the toilet after going to the toilet; The soil of the flowers is dry, so you can use it to water them. The floor is dirty, so we can use it to mop the floor. After breakfast, because the water pipe in our house is broken and always leaks, my mother often takes a bucket to catch the dripping water. Every night when we go home, the bucket is always full of water. Instead of pouring it out, we pour it into a clean bucket. We always use it when the water is cut off.
One night, I was walking home with my schoolbag on my back. On the bridge outside the school, a water pipe burst, and the emergency repair team is trying to repair it. Because of this, all the communities around the school stopped water supply, including the community where I live. As soon as I entered the gate of Gaowang Xinfan, a waterwheel flew to the center of the community. It is unlucky to stop water supply. Every household has to queue up for water. Fortunately, we have spare water at home.
Now, human beings can have water to drink when they are thirsty; What about the future? Is our Mother Earth thirsty? What is she drinking? Please save water and start from the small things around you! If mankind does not save water and protect water resources now, then the last drop of water we see will be our tears. Please cherish the source of life! Leave pure water to future generations! Don't let future generations live in the world of looking for water!
Tick-tock, tick-tock, a tap that has been unscrewed, dripping water with difficulty ... Behind the tap, there are long queues of people waiting for water, one by one anxious, and I am one of them, waiting for a long time, a long time ... Suddenly, I was awakened. It turned out that this was just a dream, but this dream was so clear in my mind that people were embarrassed to survive when water resources were scarce.
It is urgent to save water, based on the present and paying attention to details. As long as I put my heart into it, there will always be a little water-saving story around me. That's why my stingy mother taught me a lesson.
I'm going to wash my hair. As usual, my father is ready. When I put my head under the tap, the cleaning work will begin. My mother suddenly took out a washbasin and mysteriously said to me, "Beibei, before I wash my hair, I want to ask you a question: in the past, we washed our hair directly on our heads, and it took 15 minutes to wash our hair and 10 minutes to flush it." How much water does it take to wash for ten minutes? So I checked the information online and needed nearly 20 liters of water! Mother said: "this time we use the washbasin to receive water to wash our hair and see how many pots of water we need!" " "
So, my mother and I put on overshoes and squatted under the washbasin (if we have to wash our shoes when they are dirty, it will be a waste of water! ) shampoo begins! I soaked my head in the first basin of water, wiped my head after soaking, and washed it off with water initially. Then, wash the overshoes with good water (the overshoes were a little dirty at first); The second basin of water, I wash off the bubbles left on my head, then apply the bubbles to my hair, rub my hair, and then wash them off with water, so this basin of water washes the toilet (water with bubbles can wash the toilet better); The third basin of water is used to clean the bubbles left on the last head. You'd better use this basin of water to bathe the pool.
Haha, I didn't expect three pots of water to be enough for shampoo. According to the size of the washbasin, I estimate that it will take 10 liter of water to clean the overshoes, toilets and baths. It is really "one water and two uses"!
At this moment, my mother gave me a thumbs-up and said, "Yes! It seems that saving water is not as difficult as imagined. As long as we pay attention to every bit of life, a happy life is not far from us! This will not only save water, but also give others more water in case of drought! "
Tick-tock, did you save water today? Are you ready for World Water Saving Day on March 22nd?
In our daily life, water seems to be a tool that we can use at any time. We use it for washing face, bathing, washing clothes and so on. In arid areas, water is as precious as life, while the rich with clean water treat water as useless as garbage; It can be seen that water has different views on different people.
Let's think about it from another angle. If all the water on the earth is wasted by us, what kind of life will we face? I think we will guess at once that we will die of thirst. Some people think that the resources on the earth are inexhaustible, not to mention that there are many oceans and few land on the earth; If we have such an idea, we are all wet. There are about 6.6 billion people on our planet. If we save a drop of water every day, it will merge into a lake. On the contrary, if each of us wastes a drop of water every day, it will destroy a lake; Therefore, we must save water.
Don't put too much water when washing your hands; Be sure to turn off the tap after using up the water. Like people in arid areas, we can also use the water after washing our hands to clean the table, and the water after cleaning the table can be used to water the flowers and flush the toilet. In this way, a basin of water has played its basic role. Some people like flowers very much. It is really a waste to treat them as their own children and water them with pure water that people in arid areas can't drink. If you give water to people in arid areas, I wonder how many people can be saved.
If we really don't know how to save water, we might as well ask others; For example, stick "please tighten the faucet and don't let it shed tears" on the faucet; If you really like flowers, don't water them with clear water. You can wait until it rains before moving them out to water them. Or water the flowers with a rice washing stick, which can save water and make your flowers healthier.
It should be clear to all that China is a country with frequent droughts. There is a saying that about 400 cities in China are short of water, and the number of cities seriously short of water exceeds 1 10, where people died because of lack of water. Hearing this news, everyone knows the pain of water shortage! In the future, we should never regard water as a tool that can be used at any time, but treat it as precious as life.
Water is an important resource for human survival and development. Without it, there would be no life, so water is an indispensable and irreplaceable resource. In order not to let us face a life without water in the future, from now on: save water!
I am an ordinary faucet. Every day, a lot of clear tap water flows through me to where people need it. Every time I see people's expressions of satisfaction after they have finished what they want with the water flowing out of my body, I always feel happy, because I have done my part to help mankind.
We do our best for mankind, but how does mankind treat us?
The living standard of human beings is getting higher and higher, and the water consumption is becoming more and more amazing. I was born in China, a country short of water, and the per capita water consumption ranks 12 1 in the world. But it is such a status quo that China people can't wake up. Let me talk about my experience in the host family: the host family is a well-off family with a very good living standard. The hostess washed the vegetables. That's a kind of pressure! She always turns on the switch above my head without hesitation, and the water gushes down like a brave hose, which is really "magnificent". But what's the use of momentum? In the end, it ended in destruction and death. The hostess began to wash vegetables with this coarse faucet. She put the vegetables under the water. When water molecules encounter obstacles, they immediately disperse and fall around the sink, giving out a cry for help. Ta！ Hey! "They shouted at the top of their lungs and could only make a subtle sound, which humans could not hear. The hostess rubbed her hand up and down on the vegetables and could hear a slight rustling sound. It was the vegetables that gave a comfortable groan. It washed away the dust with the help of water droplets and had a clean body. The water drop, with a grain of dust, fell into the cold sink. After washing one vegetable, the hostess went to get another. She didn't turn off the switch on me for convenience. For a moment, I saw countless water droplets pouring out of my body. I want to stop them and tell them that there is an abyss below, but I can't. Poor water drop, I wanted to see the beautiful world and make some contributions to mankind, but they only felt desperate after rushing out. They can't do anything in their short life, so they fall into the sink in a hurry and split into countless smaller water molecules, ending their lives. The hostess came back and brought a handful of dishes, but I cried, tears mixed in the water drops and dripped down. Accompanied by small drops of water, it dripped into the endless abyss-sewer.
"Hey, why is there no water?" The hostess said a doubt, and I choked up, and my tears had already dried up.
Water is the source of life on earth and the most important and indispensable resource for human life. At present, the water resources on the earth are very limited, and China is one of the countries facing the most serious water shortage crisis. However, some people take it for granted that water resources are inexhaustible, so it is a pity to waste water without any distress.
Since I grew up and learned something about water, I have paid great attention to saving water whenever I use it. Once, my father and I went to the bathroom to take a bath. When taking a shower, try to let every water injection fall on me. At this moment, I suddenly found an uncle playing soap, but he didn't turn off the tap. I turned off his tap when he wasn't looking. He seemed to feel it, turned around, saw me and said to me in an unfriendly tone, "What are you doing, little friend!" " "I felt a little embarrassed at first, but according to my conscience, I didn't do anything wrong, so I calmly refuted him:" Please don't waste water. "After listening to my words, he seemed to realize his mistake and didn't say anything. Later, my father praised me for being brave and just.
I don't waste water at will in public places. At home, I also pay attention to saving water.
I planted some pots of flowers on the balcony. Because my mother had little free time, this task was contracted to my grandmother from the beginning. Grandma waters the flowers every once in a while. One weekend, my parents went out shopping and I stayed at home reading. After a while, grandma came. She put away her mother's clothes hanging outside first. Then, I went to the kitchen to get a big plastic basin, filled it with half a basin of water, and watered each basin of flowers. I watched my grandmother water the flowers, and felt it was a pity to water them with clear water, but I couldn't think of any water to water them. So when my mother came back, I asked her. Mom said that when cooking porridge in the morning, it should be watered with Taomi water. I asked my mother again, "Isn't the rice washing water dirty?" Mom says those dirty things won't have any effect on plants; On the contrary, there are some nutrients in Taomi water, which can be used as fertilizer for flowers and plants. I told grandma that I would water the flowers with Taomi water in the future, and she agreed. We all think this is killing two birds with one stone.
There are many such water-saving practices around me. For example, my father often washes clothes and mops the floor with a bath. Wash your feet with clean face washing water and so on. Let's start from now on and start with the little things around us. Everyone should know about water, pay attention to water, save water and cherish water, and make joint efforts to keep our home in a good ecological environment.
I often see such pictures on TV or newspapers: many children are forced to drink those black and dirty springs because they live in a serious water shortage environment. As a result, thousands of children in Qian Qian get sick and even die because they can't drink clean water. When I saw those tragic pictures, I made up my mind to save water and bring some warmth to those poor people.
Save water, start with me. We immediately discussed the saving plan at home, and we all came up with many good ways to save water. Some say: the water after washing your face can be used to water the flowers; Others said: the water after washing feet can be used to flush the toilet ... I saw that our family was so environmentally friendly and laughed happily.
In the days when we carried out water-saving activities, we all made a lot of contributions, but there are also many shortcomings. One day, I implemented a water-saving plan at home, but my mother didn't help me with it, just cooked my own lunch. Unexpectedly, my mother seems to have forgotten the agreement with us, and even poured the rice washing water directly into the sewer, saving no water at all. I saw all this from a distance. I immediately rushed forward to get some water, but it was too late. All the water was poured into the sewer by my mother. Oh, I'm so angry. I wish I could give my mother a scolding to get over it.
Up to now, we are still carrying out water-saving activities, but I am still angry when I talk about my mother!
Hui, you ... "I can't help blushing when I see that things have been exposed. I don't know how to answer my mother's words, so I have to answer honestly: "Mom, I just want to help you make tea." Mother looked at the cup of tea and smiled happily.
In the afternoon, I sang another song to my mother and read an affectionate poem. After listening to this, my mother immediately gave me a thumbs-up sign. Seeing my mother's smiling face is sweeter than eating honey!
May 8, this special holiday, let's do something for our mother to make her happy! I believe everyone can see her beautiful smile.
The graceful arc just hit Chen, the music teacher who enforced the law impartially on the sidelines. You can probably imagine Mr. Sun's mood at that time!
Strong, hard-working, persistent, not afraid of hardship ... These are all honed in the sports meeting. So, let's stick to daily exercise and become a strong player in the sports meeting as soon as possible!
Water is the source of life. Where there is water on the earth, there is life. People can go without food for several days, but they can't go without water for several days. How important water is to us. Plants need water for growth. Look, the water is flowing into the orchard. The peach blossoms in the orchard are as red as fire, the apricot blossoms are as white as snow, and the leaves are greener. It really looks like a colorful painting. The water flowed into the farmland, the rice planted by the farmer's uncle was harvested, the vegetable fields were green, and the wheat fields were turned over. I heard my mother say, "In the drought the year before last, some tea trees on the mountain died because they didn't go to the mountain to draw water in time. These years are different. Water is diverted to the mountain, and the tea garden on the mountain is green. " Animals can't grow without water. Without water in the river, cheerful fish and shrimp will be killed by X. Without water in the forest, animals will die of thirst. Without water, the earth will no longer have a vibrant scene.
There are many rivers in our motherland. They seem to be our mother's blood vessels, flowing slowly. Don't think that anyone is inexhaustible. In fact, water resources are limited. At present, China's water resources have been greatly reduced, making it one of 12 water-deficient countries in the world. But people are still destroying water resources. Some factories do not pay attention to the protection of water resources, and discharge industrial wastewater into rivers and lakes, causing pollution in many rivers and lakes, leading to the death of fish and shrimp in groups, and people get sick because of drinking polluted water. Some people lack environmental awareness and have poor living habits. They often dump their garbage into lakes and rivers, causing water pollution.
Water has brought progress and prosperity to human society, but human beings constantly pollute and destroy it in the process of progress. This has also affected human health, and these things can't happen again. We should cherish water from childhood, don't throw rubbish into the river, and don't wash dirty things in the river. If you see someone pouring dirty water into the river, you should stand up bravely and stop them from destroying the water source. Especially the river around the city, the water is so clear and the river surface is so clean, which makes people relaxed and happy. How can we have the heart to destroy it?
Water is a huge resource belonging to human beings on the earth. We should cherish and cherish her, because she has done many good things for people. I want to write beautiful sentences for her, draw beautiful pictures for her and sing beautiful songs for her. Let us all cherish her and let her shine forever.
