"Isn't there water in our jar?"
"The water in our jar is fishy and smelly, which makes me dizzy. It tastes terrible. I really can't drink any more, "said the deer indignantly.
"Well, good boy, bear it! It is difficult to find cool and delicious water to drink anywhere now. "
"Why?" The deer asked curiously.
"Because in recent years, large and small factories and drainage channels have multiplied, so that a large amount of sewage has rushed into the river and flowed into the sea. People often dump piles of garbage into rivers and spray chemical fertilizers everywhere in the countryside. . Water resources are wantonly destroyed. Now, even our biggest Lake of Dreams has no water. "
"I don't believe it. Isn't there a lot of water in the lake a few years ago? Mom, you must take me to see what happened.
When you say go, the deer and mother are on their way. Walking, the deer found a river ahead, and it rushed forward excitedly. Suddenly there came the heartbreaking cry of Sister Xiaoyu by the river. The deer came to the river and saw many fish showing their white bellies in the lake. "Fish, fish, what's the matter with you?" "I, I am here. . You run. The water pollution here is too serious. If you can, after I die, get me ashore and leave this stinking water. " Say that finish, small fish closed his eyes.
"Mom, how did this happen? "The deer shed sad tears.
They walked on and finally came to Lake of Dreams, but what they never expected was that there was only a pool of mud left in Lake of Dreams today.
Uncle Menghu, are you sick?
"Well, because of the long drought and no rain, my body is constantly decreasing. In a few days, it will be gone." It sighed and said, "all this is caused by human beings!"
Hungry and thirsty deer licked his chapped lips and said, "Man, why did you destroy our home?"? Why? " ? "
Mother deer didn't speak, but she showed helplessness.
I like drinking water. After playing a ball game, my clothes were all wet. At this time, I feel very thirsty and my throat seems to be smoking. Nothing is more important than drinking water. I hurried home, forgot to change clothes, filled the tap with tap water with a mug, picked it up and drank it. My mother saw it and quickly stopped me and said, "There are bacteria in raw water. If you drink it, you will get sick. Stop drinking! "
So I ran to the kitchen, opened the refrigerator and took out a bottle of iced drink. Mother added, "You have just exercised so much, and now you are all hot.". If you suddenly drink iced drinks, it will damage your stomach. "
I argued that the boiling water in the thermos was too hot, and I couldn't wait.
At this time, I saw my mother take out a big cup from the kitchen cabinet and hand it to me, saying, "You are sweating so much, and a lot of salt is lost in your body." It is best to drink a glass of light salt water. " This cup of warm boiled water is salted. Mom has prepared it for you. "
I picked up the cup and gulped down the warm light salt water. I feel so happy and happy, at the same time, I also have a feeling of gratitude: mom is so good! How thoughtful of her!

3. Write a composition about water, 400 words.
In life, although people slogan shouted: "Protect the environment". But some people are still wasting the earth's resources.
One day in the summer vacation, my father asked me to go to the vegetable market factory to buy food, and bought cabbage, celery and so on. Suddenly, I remembered that my father asked me to buy garlic before going out. So I went to the garlic stall.
I bought garlic, and when I turned around and walked back, I saw that the faucet above the pool where the stall owner was scraping fish scales was wide open, but the stall owner went to chat. I think of an article saying that the drinkable water on the earth only accounts for about 3% of the world's water. China is a country short of water, and about one third of the population is short of water. I really want to persuade the stall owner to turn off the faucet, but I'm afraid the stall owner is unreasonable. When I was hesitant, I remembered that the teacher taught us that it is everyone's responsibility to protect the environment. So I boldly went over to the vendor and said, "Uncle, you can't waste water. You must turn off the tap. " I pointed to the tap. Go ahead, go ahead, mind your own business.
I am very angry, this man is so unreasonable! I was about to refute him loudly, but reason prevented me from doing so. what am I supposed to do？ By the way, I can convince him with what I know about materials. So I went over to him and said, "Uncle, please turn off the tap. You know, the water available for people to drink in the world only accounts for about 3% of the world's water, while one third of people in China are short of water. If everyone wastes water, how can we survive in the future? " My words convinced the uncle, who quickly turned off the tap and said to me, "thank you, little friend!" Without your guidance, I would have become a sinner. " Everyone around us laughed.
When I walked home, I felt the sky was bluer. I made a little contribution to environmental protection today. I think if everyone saves water and electricity and doesn't waste the earth's resources, our home will become better!
4. Drink plenty of water. Today, I came together and found that my mouth was so dry that I couldn't open it. One of them is very painful. I ran to the glass of water and drank it in one breath. I found it a little better, but after a while, my mouth stopped.
It hurts. I asked my father why my mouth kept hurting. My dad said it should be getting angry! Dad also said to drink more water, so as to get better. I asked my father if he wanted to take medicine! Dad said of course, otherwise how could it be better? Babalj 'an
Busy going to the market to buy medicine, I have been drinking water at home, alas! Anger is really bad! The most hateful thing is that there are fire bubbles on my mouth. What a pity! It really hurts there! I drank it as soon as dad got back.
I felt better after taking the medicine, but my mouth became more and more serious the next day. It was really bad to get angry.
From this, I learned: drink as much water as possible. If you don't drink water, you will get angry. I will drink more water and stop being angry!
5. Write an 800-word composition about drinking water and health. The content is novel. Look at this: water is a compound composed of hydrogen and oxygen, and it is one of the best solvents. Most chemicals have certain solubility in water. It is not only the reaction medium itself but also participates in many chemical reactions, so it is called the source of life.
Life comes from water, which provides the premise for the appearance of various substances in nature. As the geography textbook says, the lithosphere, biosphere and PEDOSPHERE appeared after the appearance of the atmosphere and hydrosphere. On this planet, all kinds of animals and plants are inseparable from water. For people, the meaning and value of water is very important.
Water is an indispensable part of human body, accounting for about 70% of human body weight. All kinds of chemical reactions in the body must be carried out in body fluids with constant concentrations of hydrogen ions and electrolytes, and body fluids are composed of ions ionized by water in the body and acids, bases and salts dissolved in them, which can be divided into intracellular fluid and extracellular fluids.
The imbalance of water, electrolyte and acid-base will affect the functions of many organs, especially muscle contraction and nerve conduction. The amount of water in and out of a normal body is balanced. Water enters the body through various foods and direct drinking, of which direct drinking is the most important way. At room temperature, the water evaporated from the body surface and breathing every 24 hours is about 800 ml, and the urine output of the kidney every 24 hours is about 65,438+0 ~ 2 liters. Generally speaking, a healthy adult needs 2500 ml of water every day and night, of which 65438 ml is taken from food.
However, in the case of rising temperature, falling humidity or strenuous exercise, sweating a lot, etc. The human body will also lose a lot of water, so the amount of water needed by the human body is not constant. The role of water is enormous, which is conducive to the normal operation of blood flow, body temperature regulation, digestion and absorption of nutrients. Due to the hot climate, sweating a lot during labor or exercise, a lot of water and salt in the human body will be lost, which can lead to heatstroke in severe cases.
At this time, the human body needs to replenish water by drinking water. Improper drinking water will cause water poisoning or other diseases. Although water is called "the source of life", it should be just right and scientific in the process of drinking water. Mineral water can be divided into natural mineral water and artificial mineral water.
Mineral water contains a variety of trace elements necessary for human body, such as nitrogen-containing mineral water in Conghua County, Guangdong Province, located in Yuntai Mountain, Jiulibu. Water contains trace elements 16, such as silicon and lithium, and rare earth elements 12, which are beneficial to human body. Mineral spring beverage made of natural mineral water has health care function for human body, and can relieve summer heat and quench thirst, and treat diseases such as gastrointestinal diseases, hypertension and arthritis.
Artificial mineral water is formed after ordinary tap water is purified and disinfected by mineralization device, which increases minerals needed by human body, such as trace elements such as calcium and magnesium, and also has health care function. Therefore, mineral water is beneficial to the heart and spleen and prolongs life.
Scientific research has proved that the food we eat provides 36 elements, among which oxygen, nitrogen, hydrogen and carbon account for about 95% of human body weight, which is the basis of starch, fat and protein. The remaining 4% of human body weight consists of calcium, phosphorus, potassium, chlorine, magnesium and iron, and the rest of human body elements account for about 1% of human body weight, including copper. Phosphorus deficiency can make people anorexia, weakness and discomfort, and feel headache. If we sort the 1 1 main elements in human body by weight percentage, they are: oxygen, carbon, hydrogen, nitrogen, calcium, phosphorus, zinc, sulfur, sodium, chlorine and magnesium in turn. Mineral water can supplement minerals needed by human body, so it is very beneficial.
In order to meet the needs of consumers, in recent years, the market has chosen a kind of natural drinking water product with rich nutrition-mountain spring water and mineral water. Most of the natural water bodies of mountain spring and mineral water are weakly alkaline.
Weak alkaline water can prevent or alleviate some diseases of human body. Drinking such water for a long time is also conducive to regulating the acid-base balance in the human body and is beneficial to the human body.
In the spring water, there is another kind of metasilicate spring water, which also has a certain regulating effect on the acid-base balance in the human body. So we advocate people to drink natural mineral water or mountain spring water.
The calcium content of pure water accounts for about 65438 0.38% of human body weight, which is the main component of bones and teeth, and plays an important role in maintaining the normal contraction of myocardium and promoting blood coagulation. Therefore, people should constantly supplement calcium throughout their lives.
Magnesium accounts for about 0.04% of human body weight, of which 70% exists in bones, and each person needs about 0.3 to 0.5 grams of magnesium every day. Some of these two elements come from drinking water. Pure water is a kind of soft water without calcium and magnesium ions, and its soluble solid content is also very low.
Therefore, people can't expect to absorb beneficial elements and supplement calcium, magnesium and zinc while drinking pure water. The effect of any harmful substances in this soft water will be amplified. A small amount of harmful substances in soft water will have greater harm and negative effects on our health than the same amount of harmful substances in hard water, so it can be said that drinking pure water has little benefit. In order to eliminate the public's concern that pure water is too pure and has no nutrition, many pure water companies have introduced a kind of drinking water called "mineralized water".
It is made by adding mineralized liquid of minerals needed by human body on the basis of pure water. Therefore, these macroelements and trace elements (such as calcium, magnesium, zinc, strontium, lithium, selenium, iron, manganese, cobalt, etc. ) is in ionic state and has good solubility.
However, is this "mineralized water" pure and nutritious and easily absorbed by the human body? In fact, mineralized water is not a natural product and is not easily absorbed by the human body. If you drink such water often, you are prone to gallstones and other problems, so it can not only provide the necessary energy for the human body, but also cause harm to the human body.
So these aquatic products are not easy to drink too much. People will sweat a lot when they are excited. Sweat contains a lot of salt, including minerals such as calcium, magnesium and potassium.
If you just drink boiled water, you will not only fail to supplement nutrition and eliminate fatigue, but also sweat more. The more you sweat, the more salt you lose, which is easy to cause muscle fatigue, pain and even cramps.

6. Write an essay entitled "Teacher Drinking Water" about 100.
Every time I go to Mr. Shen to study my composition, I always encounter an annoyance. When Mr. Shen comes, he will bring a "follower"-a water bottle, and I will sit next to where Mr. Shen puts the water bottle. The first thing Miss Shen did when she entered the classroom was to put down the water bottle. I often touch the water bottle when he is not looking. The water bottle is always full and the shell is warm.
Sometimes, Miss Shen's water bottle will hinder me from writing a composition. Whenever I have an idea, Mr. Shen puts the water bottle on the table with a bang, so my idea is disturbed by his water bottle. I really wanted to throw away Miss Shen's water bottle! However, how dare I? Alas! Let's bear it! He is a teacher and I am a student! Students should ask the teacher to score three points.
It seems that Mr. Shen really knows how to drink water. I changed three compositions and drank two mouthfuls of water. Hearing the sound of "Gollum, Gollum", I knew that Mr. Shen was drinking water again. Mr. Shen also likes to open the cup, pour the water from the water bottle into the lid and drink while blowing. Sometimes Mr. Shen makes the "grunt" sound of drinking water very loud! He often frowns while drinking water and explains his composition to students. Teacher Shen's way of drinking water is really poor!
I thought that writing this composition would be criticized by the teacher. However, when I handed it in, I saw that instead of criticizing me, the teacher praised me and asked me to continue writing! Keep writing! Tell me about my teacher Shen. Is it weird?
7. Write a composition on drinking water by yourself 150 With the continuous development of society, smoking has become a fashionable thing among some middle school students, and even many middle school students have fallen into the situation of smoking and cannot extricate themselves. Outside the school, middle school students with cigarettes in their mouths can be seen everywhere. It is understood that some middle school students have even smoked for ten years. On campus, it is often found that there is only one half cigarette for two people in the corner. You take a bite and I'll take a bite, as if enjoying something delicious.
In my opinion, students should be made aware of the dangers of smoking: first of all, smoking will affect their grades. Because once you are addicted to cigarettes, your mind is full of cigarettes, how can your academic performance be top-notch? Secondly, nicotine in cigarettes is harmful and has a great impact on the health of teenagers-it can cause many diseases such as lung cancer. Third, middle school students have no financial resources. Where does the money for cigarettes come from? Those with good family conditions also have pocket money; What should I do if my family is embarrassed? If you don't quit smoking, you can only find another way out, either to work, to steal, to rob, and to commit crimes. The latter case is everywhere and heartbreaking.
Faced with the situation that many middle school students smoke, as teachers and parents, they will definitely not let themselves go. Some parents and teachers patiently guide and guide them to realize the harm of smoking and consciously quit smoking; Some parents rushed up, punched and kicked, and drove out of the house. Needless to say, the former is correct and effective; The latter, because of the wrong method, makes things develop in the opposite direction of goodwill.
There are many reasons why middle school students smoke, mainly because some parents don't set a good example for their children and some bad factors in society. If every middle school student can realize the harm of smoking and think that smoking is not a good thing, then middle school students can stop smoking.
As parents, we should first set an example by not smoking. We can't imagine that it would be "good" for a smoking parent to educate their children not to smoke.
In addition, there is not enough publicity on the harm of smoking in society. There are still a large number of smokers among middle school students, and cigarettes are still sold in large quantities, which makes some middle school students unable to resist the temptation of smoking and join the ranks of drowning.
Obviously, to put an end to the social phenomenon of middle school students smoking, we must strengthen school education and social propaganda. Therefore, I call on the society to contribute to preventing middle school students from smoking, and vigorously publicize the harm of smoking for the benefit of future generations.
I think middle school students draw 700 -800 words anonymously.
8. How to write Xiao Ming's composition about drinking water?
Xiaoming is doing his homework this afternoon. Feeling a little thirsty, he went out of the small room to drink water.
I found my grandparents not in the living room. I looked in the kitchen and they weren't there either. Just as I was about to go to the balcony, my grandmother came over. My grandmother has always been very strict with me, and I am most afraid of deserting my homework. In order to make grandma think that I am concentrating on my homework and keep my "glorious image" in grandma's mind, I quickly hid under the desk not far from me.
Fortunately, my grandmother didn't notice. Just want to go out and stop, thinking: grandma will come back soon. If I go out now, my grandmother will surely find out. Sure enough, just when I took back a leg, my grandmother came over, and I secretly felt glad for my decision just now. After waiting for a long time, my grandparents still didn't come out. I couldn't wait any longer, so I walked gently and carefully to the coffee table. Suddenly, there was a burst of footsteps in my ear. I hid in the bathroom at lightning speed. I peeked out of the bathroom and saw grandpa coming.
After grandpa left, I crept out of the bathroom. Suddenly, grandma's stern voice came from behind: "Why don't you do your homework?" ? ! "Well, as the old saying goes, a cunning fox is no match for a good hunter! I had to come out quietly!
Today's "adventure" is really * *!
