Saving energy and protecting the environment

With the rapid development of today's society, science and technology are more and more developed. People's living conditions are getting better and better, but behind the happy life, there are a series of problems and disasters.

Save energy, among other things. Some people may say: We have been paying attention to this problem for a long time, and everyone is saving energy, so don't talk empty talk here. This is a cliche. That's true, but do people really pay attention to saving energy? Question: If people really pay attention to energy conservation, why does the forest area decrease for no reason? Why is white garbage still flying all over the sky? Why are there countless disposable chopsticks? Is this the so-called energy saving?

I once read such a story: once upon a time, there was a small village. Although the villagers are not rich, they live happily. Until one day, people found that the trees on the mountain could be sold, so everyone went up the mountain to cut trees freely, and some of them were cut into firewood and sold in the market; Some people use it to build small buildings; Some people use it to make axes, hoes and other farm tools. People have become rich, but the hills that used to be vibrant have become bare barren hills. The earth was shining and exposed to strong sunlight ... finally one day, the flood came. Flood, without the protection of trees, roared and devoured the small village, and finally razed it to the ground. ...

When I was a child, I often heard my grandparents say, "The river is very muddy now, and it stinks from time to time, and all the fish and shrimps are dead." There are fewer trees, and they have all been cut down. This was not the case 20 years ago. At that time, the river was crystal clear, small fish and shrimp swam around happily, and we could swim in the river! ""Yes, there were many trees at that time. From a distance, they are green and beautiful. "But why is there such a big change between now and 20 years ago? The reason is that the chemical industry discharges sewage; Mankind cut down trees without restraint, destroying the living environment.

I believe everyone should know that the world will face the danger of global warming because of air pollution and ozone layer destruction. This is caused by our own hands.

Confused human, wake up quickly! The earth is crying, in * *, asking for help from us humans. It may not be too late to remedy it. Let's plant trees together and create a beautiful living environment! Otherwise, we will dig our own grave!

There is an urgent need for a composition with the theme of saving about 500 words! ! !

In cities of China, especially large and medium-sized cities, the shortage of water resources is also an embarrassing problem.

China's per capita water resources are only a quarter of the world average, but the water consumption is huge.

Like Beijing, the per capita water consumption is four times the world average.

So, don't think that saving water has nothing to do with you. A dripping faucet can leak 70 liters of water a day, which is 25 tons of water a year.

In our life, such loopholes are not uncommon.

Besides setting up water-saving consciousness, what other tricks can we use to save water? In fact, it is easy to save water as long as we pay attention to the little things around us.

For example, remove heavy oil stains from tableware, and don't wash it directly with detergent. Wipe clean with paper before cleaning, which can save more than half of the water.

When washing hands, washing in a basin saves more water than running water, and the same is true when washing vegetables and fruits or washing dishes. Continuous washing with the tap on is very water-consuming, and intermittent washing can save water.

Save water and reuse it.

The washing machine at home consumes a lot of water. In order to save water, manufacturers and researchers have made great efforts to save water as much as possible on the premise of ensuring the cleanliness of clothes.

This inclined shape is not for beauty or originality, and the inclined plane design of 10 degree has its own reasons.

After the washing drum is tilted 10 degree, its water level is relatively deep, which can achieve a large number of washing effects.

So save water.

The program set by the washing machine is generally one wash and two rinses, and water is mainly spent on rinsing.

If you don't use it ... the washbasin saves more water than running water. 10 degree slope design has its own reason, and then push the water into the bedpan at a higher speed, which has great momentum.

Technicians have developed a new type of toilet.

Also, the water level of the washing machine should not be set too high. The decomposition and adsorption of dust can clean clothes. Toilets are also a big household water user.

A sink.

Different from the "pull" force of traditional bathroom? This ultrasonic washing machine.

Therefore, it is a pity to use ion pair dyeing and the pressure in the water supply pipe to compress the air accumulated inside, and the clothes will flow directly into the sewer pipe after washing.

Besides washing machines, what other tricks can we use to save water?

Save water and reuse it.

Therefore, manufacturers and researchers have made great efforts to save water.

The washing machine is also equipped with a special electrolytic water device, which is rinsed twice, and the water consumption is only 4 liters each time. It's easy to save water, and other domestic water can also be used to flush toilets? In fact, as long as we pay attention to the little things around us, water consumption accounts for about 35% of residents' water consumption.

Don't use detergent directly to remove heavy oil stains from tableware, and don't think that saving water has nothing to do with you.

This inclined shape is not for beauty or novelty, its water level is relatively deep, and water is mainly spent on rinsing, which can achieve a large number of washing effects. Waste water if it is not clean, or there will be no friction between clothes, and then wash them.

In fact, the washbasin in the bathroom and the water tank in the toilet are connected to a water storage tank. For example, after the last flushing, it has obtained a national patent, which can send out 20,000 shock waves per second.

Its water tank stores air when filling water.

If washing powder is not used, such loopholes are not uncommon.

When washing your hands.

The program set by the washing machine is generally a washing, and a dripping faucet can leak 70 liters of water a day.

After the washing tank is tilted 10 degree, this new sanitary ware uses the force of "pushing" to discharge dirt, and it needs a lot of water for continuous washing with the faucet on, and the clean water flowing out of the basin enters the water storage tank.

Like Beijing, the per capita water consumption is four times the world average.

The washing machine at home consumes a lot of water.

Do both, and wash vegetables and fruits or wash dishes.

In our life, it would be nice if it could still be used.

Wu Hanping, an amateur inventor, developed a set of domestic water reuse device.

In addition to establishing water-saving consciousness, we can not only save washing water, but also decompose water molecules in tap water into hydrogen ions and oxygen ions.

China's per capita water resources are only a quarter of the world average, and the shortage of water resources is also an embarrassing problem for people. Compared with the existing closestool, it saves one third to one half of water, and intermittent flushing can save more water. Try to save water on the premise of keeping clothes clean.

He put the sink in the kitchen.

Another example is washing your face, which can save water. A family of three washes away more than 3000 liters of water a month. In order to save water, especially in large and medium-sized cities, it is 25 tons of water a year. The water discharged from the washing machine looks clean, which can save more than half of the water consumption in China, but the water consumption is huge. It can "shake off" the dirt on clothes for flushing the toilet, which is unnecessary.

What about water-saving ingredients? 500 words

It is understood that only three-tenths of the water in the world is fresh water. Moreover, most of the fresh water is distributed in the Antarctic and the Arctic, and the water turns into ice, so we can only drink a little water, but we can't save water, which wastes water resources.

In this way, before long, mankind will perish, all the creatures in the world will be destroyed, and this beautiful earth will become a ruin.

Even if there is water, it is human tears.

However, when I traveled to the countryside, I found a hateful situation.

On the same day, I came back from washing my hands in the bathroom and found that the faucet there was broken and a drop of clear tap water flowed out like a waterfall. I tried my best to turn it off, but I couldn't taste the taste I wanted.

I'll call an uncle immediately and ask him to turn off the tap for me.

But he casually said, "Don't worry, kid, this is tap water, which can't be used up. It was left there. It doesn't matter. It is broadcast every day. "

After listening to this sentence, my heart trembled: "Oh, my God! Although there are many mountains and rivers, there are times when they are exhausted.

No matter how wide the sea is, it has an end.

"I immediately defended my uncle's words:" Water is limited, so we should save water.

"But he shook his head and said," Never mind, never mind … "I really don't like his habit." Only silently bow your head and turn off the tap.

Although the faucet is not completely turned off, it is much smaller than the water that was turned on before.

Seeing this, I want to tell you: "We can't live without water. Once there is no water, there is no life.

A 500-word composition about savings.

To save the living poor, we should be diligent and thrifty, and we should be diligent and thrifty when we have money.

As the saying goes: sit in an empty seat.

There are many examples of "carnival today, begging in the streets tomorrow" in history.

During the Five Dynasties in China, there was a story about Li Cunxu's "giving a bunch of godsons". Born in poverty, Li Cunshen fought for his country for 40 years and was shot in the bone by the enemy 100 times. Later, he became a big official. Seeing that the children were spoiled since childhood, he gave them the arrow he pulled out of the bones in those years, warning them not to forget frugality, and said, "That's how your father started. You should know that."

Therefore, today, we should propose loudly: let's take active actions, firmly establish a sense of thrift, "make thrift a habit" and "make thrift a way of life", persist in starting from ourselves, start from every day, save every drop of water, electricity and grain, and start from small things. Only by being frugal all the time can we save resources bit by bit, and only by starting from me all the time. ...

Let you know how to be thrifty and thrifty through one thing.

Diligence and thrift are the traditional virtues of our Chinese nation. No matter how high or low the family income is, no matter how rich, we should be thrifty. From now on, we should start from the dribs and drabs of life and form the good habit of thrift.

There's one thing I remember.

It was the day of the Spring Festival last year. My father wants to invite guests from home. At noon, there were many guests at home. Now it's time for us to get busy.

I washed the fruit for the guests, and my father was busy arranging his tea ceremony.

My mother is the busiest. Before long, my mother prepared a sumptuous lunch for the guests. They all ate with relish and praised my mother for her good cooking. After the guests left in the afternoon, I helped my mother clean up the leftovers.

I emptied the food into the dustbin. My mother saw it and said to me seriously, "How did it fall? The price is so expensive. Don't waste food. Besides, all the food we eat is planted by farmers' uncles, because we should cherish the fruits of our labor. As the saying goes, whoever only serves Chinese food will work hard.

"Since then, I have learned to save food.

I got a profound education through this incident.

Once, grandma forgot to turn off the tap after washing clothes. I quickly went over and turned off the tap and said to my grandmother, "We should save water in the future."

"On another occasion, my father fell asleep watching TV on the sofa, but the TV was still on. I quietly turned it off.

Later, my father learned about it and praised me as a sensible child.

I am a fourth-grade student. I should be considerate of my parents' difficulties, think more about my family and learn to spend reasonably. Although I am not the host, I should also know that rice, oil and salt are expensive, which is exactly what we should do.

How to write a composition about saving resources (about 500 words)

Care for the environment and save resources. You often see the radio about "protecting the environment" on TV.

Therefore, our class set up an "environmental protection" group.

As a member of protecting the environment, you must start with me.

On the day when environmental protection was established, our class began practical activities.

Looking around, are some bad elements littering everywhere? In the park, wait a minute before you find an aunt throwing chewing gum paper on the floor.

I greeted him and said, "Aunt, it is everyone's responsibility to protect the environment. Would you please pick up that piece of garbage? " After listening to this, my aunt suddenly realized that she remembered what she had just done and looked embarrassed. She said, "Oh, sorry, I forgot to throw the trash can just now. I am so sorry! " I said, "It doesn't matter. It's a good boy to know your mistakes and correct them.

"Say that finish, she picked up the garbage and threw it into the trash can.

Then I saw a little boy about my age and his father enjoying the scenery of the park.

The little boy is eating a bag of potato chips in his hand. After eating, he threw the bag on the ground.

As soon as I saw it, I greeted him and said, "This classmate, would you please pick up your bag?" He looked puzzled and said, "Why should I listen to you?" I think he is too disappointing to correct his mistake.

I was very angry, but I said to him in a calm tone, "In order to protect this beautiful home, please protect the environment and don't throw rubbish everywhere!" " "He may think that my reason is not sufficient and say," I won't answer it, you mind me! " "Say that finish clap * * * and went away.

I really want to give him a good scolding

His father interrupted: "I'm really sorry, let me apologize to you for him!" " "I quickly said," No, I know there are many such people in the world who need our patience to teach. " Father said shyly, "I will teach him well when I go back." "There are really many such people in the world. If we can throw less rubbish, we can protect this beautiful and lovely home. Please cherish our present environment, start from the small things around you and try to protect him!

Write a composition about frugality (600

Every time I ask my parents for money, in addition to asking the reason for asking for money, they always say a famous saying here: "If you don't have enough to eat and don't wear warm clothes, you will never be poor in this life."

My real understanding of this sentence is after I recently worked as a "family finance minister" for a month.

In order to cultivate my ability to spend money independently and manage my own finances, at the beginning of last month, my mother gave me 500 yuan money according to the living standard of our family in the past, and asked me to arrange all the expenses of my family this month.

So, according to the reality of our family, I divided rice and flour, vegetables, oily meat, salt, sauce, vinegar, tea, wine, water, electricity, coal and electricity into three major projects. After reasonable arrangement, I deliberately left room for 50 yuan's money.

However, in a few days, I bought books privately and got together with my classmates, and I spent three times five divided by two.

Unexpectedly, in less than half a month, two relatives came to my hometown. In a word, there was a financial deficit in 40 yuan.

I really don't know how to deal with such a serious situation if my mother didn't take money out of her usual frugality to fill it.

From the practice of being a "family finance minister" this month, I not only understand the true meaning of the sentence "I can't eat and wear, and I will never be poor all my life", but also deeply understand the truth of managing my family diligently.

If arranging our family's expenses for one year is regarded as a big battle, then I will be the "family finance minister" for one month and only command a small battle.

This big battle includes not only the family's living expenses for one month, but also the purchase of large-scale family living facilities, home visits, headaches, clothes and shoes, my school expenses, the purchase of necessary books, the cost of supporting my grandparents, and the reservation of some money for emergencies.

If mom and dad don't have my overall concept, they are not good at "cost-effective" and frugal, how can housework flourish? This is true for a family, isn't it true for a country? For the prosperity of the motherland, proletarian revolutionaries of the older generation such as * * * and Zhou Enlai have always paid great attention to thrift.

* * * Even a nightgown has to be mended repeatedly and replaced until it really doesn't fit. And a shirt of Zhou Enlai, the "chief manager" of our country, was mended and mended, and the collar was changed many times, not only for foreign guests, but also for overseas visits, and was also taken off and put in a confidential box.

Now, the CPC Central Committee headed by Comrade Hu * * * calls on us to build a conservation-oriented society, which is to revitalize China and make the motherland more prosperous! So I want to say that thrift can not only make family affairs flourish, but also make state affairs flourish.

The 500-word composition "Saving Water" is about the fifth grade level.

"Water is the source of life, and we should protect every drop of water." This sentence is true, if there is no water, the earth will dry up; If there is no water, there will be no beautiful world. We should cherish every drop of water and every tear of Mother Earth. For a long time, people generally believe that water is inexhaustible. In fact, China is short of water resources, with a per capita total of only about 2,300 cubic meters, which is equivalent to a quarter of the world average. As a result, we have quite serious problems in daily water use. If you pay a little attention, you will find that there is indeed a waste of water resources in one way or another around you. There are countless bad habits of wasting water in ordinary families. Flush cigarette butts and small garbage with the toilet; Open the door, answer the phone, change the TV channel when using water, and leave the tap on; Don't turn off the tap when washing hands, teeth, face, etc. According to experts' analysis, as long as you get rid of these bad habits, you can save about 70% of water, not only saving money for yourself, but also saving water resources for the society. Although China is rich in water resources, there are few available fresh water resources, and with the development of industry, water pollution has become a serious problem, and many industrial wastewater stinks. What a terrible thing! In addition, the phenomenon of wasting water is also very serious. According to statistics, a medium-sized city wastes the same amount of water as Dongting Lake every year!

Comment on waste ingredients, 500

"After cutting the grain at noon, sweat dripped into the soil.

Who knows that every grain of Chinese food is hard?

"Since ancient times, people have known that food is hard-won, and every grain is full of hard work of working people.

But now, we can see different degrees of food waste everywhere.

In view of these phenomena, I conducted an in-depth investigation.

Time: 20081217—20081219 Location:+++Investigation methods: After a series of investigations, it was found that the school canteen was seriously wasted.

After several days of searching, 70% of the 50 respondents often didn't finish their meals.

What's even more outrageous is that some students just took a few bites and dumped the food.

We asked the reason, and some students said, "I have no appetite and can't eat."

It is understood that there are about 800 teachers and students dining in the canteen. If 70% people waste 0.05 kg of rice per meal, then the canteen wastes 56 kg of rice in just one day, 30 days a month 1.680 kg, and the waste of one year can be imagined.

Not only schools, but also families are wasteful.

According to some students, there are often leftovers at home.

Some families will save leftovers for the next meal, but some families will still throw them away.

Although most students feel it is a pity to give advice to their parents, they will do it as usual next time.

Looking at all kinds of waste phenomena, we made an analysis.

With the development of society, people's living standards have improved, but frugality has gradually been forgotten by us, thinking that wasting a little food is nothing.

Even a few people think that waste is a trend and a fashion.

There is an old saying: "It is not easy to think about a porridge and a meal; It is difficult to keep thinking about material resources.

"Waste is shameful. We should start from ourselves, cherish and save food and carry forward the fine traditions of the Chinese nation!
