Water nurtures and sustains all life on Earth. Human societies cannot exist without water. In many regions and cities in China, there are varying degrees of water shortages.

Conserve water, protect the limited source of life, and if water resources are not cherished, the last drop of water will be human tears. The water-saving action starts from me, and it will never stop!

Look at this scene: an old farmer slid a seven or eight-year-old child to the bottom of a deep well with a thick rope, just to scoop two halves of drinking water with a little mud on it. When a farmer boiled water in a pot, one ring of the pot turned out to be a whitening alkaline sediment.

They have been drinking such water for many years. Look at this scene again: the water is running in order to wash a towel.

And many of these similar behaviors happen to us all the time. Water danger is not far away from us, saving water and protecting the environment is the most basic obligation of every earthling.

Nowadays, water conservation has become the focus of attention all over the world, and March 22 is designated as "World Water Day" every year. The week of March 22 is designated as "China Water Week", and it seems that this is the only time when most people realize that our water resources are very limited. Therefore, enhance the awareness of water conservation of the whole people, this awareness should not be just a day, a week, it is a sustainable development topic, which requires the unremitting efforts of every generation and everyone, everyone cares, saves water, opposes waste of water, pollutes water, and nature can live in harmony with us.

It was late at night, and the moonlight filtered through the window and scattered it all over the ground. I sat alone at my desk, letting my tears wet the meagre paper.

This time, I was far from achieving the expected results for the final exam. I am wronged, why do I pay so much, but every time I don't even get a little gain, I complain that God is unfair. Unconsciously, I remembered the scene of reading at night, and the scene when my parents brought me bread and milk.

Why, why, am I really not the material for learning?

Forget it, don't think about it, turn on the light and take a look at the extracurricular books, I turned on the desk lamp. I found that the cookie crumbs on the table were moving, I pushed my glasses, trying to see clearly, only to see a few ants moving the biscuit crumbs, the biscuit crumbs moved and stopped, as if they were very difficult to move, really interesting!I brought a magnifying glass to take a closer look at these little things.

I'm also going to put some "barriers" on them. I put my pencil in front of them, and I saw that they were about to change direction, and I surrounded them with the pen to see what they would do this time! I used a magnifying glass to observe carefully, a leading ant climbed on the pen first, this is like a commander, one after another several ants climbed up, they wanted to force the biscuit residue to pass, but after several attempts were unsuccessful, the leading ant lifted the biscuit crumb, the ant behind it pushed hard, and it took about thirty minutes, and the biscuit crumb was finally transported by the ant from the pencil.

I suddenly realized that even such a small ant is not discouraged in the face of setbacks, and we humans should dare to face setbacks, and I remembered: Edison's laboratory was bombed, and in the face of such setbacks, Edison did not lose his fighting spirit, and in just three weeks, he successfully invented the gramophone; Beethoven is deaf in both ears, which is undoubtedly the biggest setback for a ** family, but Beethoven did not flinch in the face of setbacks, he said: "I want to choke the throat of fate."

In this way, Beethoven composed the world-famous Symphony of Destiny.

There is wind and rain on the road of life, and there are thorns everywhere, only if we struggle and fight, there will be flowers and applause waiting for us. Famous people have said that setbacks are a bottomless abyss for the incompetent, and a tiptoe to success for those who dare to face setbacks.

I opened my textbook again, and the first rays of the morning sun shone into the room, and where I fell, I got up. I laughed, setbacks, I challenge you, life is more exciting because of setbacks.

Brilliant 30 years.

The founding of the People's Republic of China in 1949 completely freed the motherland from the situation of oppression, and China, the sleeping lion of the East, began to slowly awaken, but it was difficult until 1978, when the Third Plenary Session of the 11th Central Committee of the Communist Party of China made a new decision to comprehensively implement reform and opening up; Since then, the spring breeze of reform and opening up has rejuvenated the land of China, and the Chinese nation has finally embarked on the great journey of national rejuvenation!

In the 30-year journey, the Chinese nation has re-established itself among the nations of the world with a new attitude; 30 years of vicissitudes of life, 30 years of glorious history, cast a nation's dream of nearly a hundred years!

The 30 years of reform and opening up have been 30 years of rapid economic prosperity in China! High-rise buildings have risen from the ground, the people's living standards have been continuously improved, China's comprehensive national strength has been continuously enhanced, and its international status has been continuously enhanced, and no major matter in the world can be held without China's participation, and China is playing an important role in the international arena more and more. The 30 years of reform and opening up are 30 years of social harmony and stability in China!

The Chinese nation is as impregnable as the Great Wall of Steel! Hong Kong returned in 97 and Macao returned in 99; In the face of the rare catastrophic flood in southern history in 1998, the terrifying SARS epidemic in 2003, the ice and snow disasters in more than a dozen provinces in 2008, and the great ** in Sichuan, the sons and daughters of China united as one, holding hands and trampling one ordeal after another.

The 30 years of reform and opening up have been glorious 30 years. We must study hard, master scientific and technological knowledge, strive to build ourselves into useful materials for the motherland, and use our hands to build the great motherland and build our motherland into a stronger and better country in the future. We firmly believe that on the journey of the great rejuvenation of the Chinese nation, there will be one glorious 30 years after another!

The rise of the Chinese nation will surely make the world proud of us!

Then you might as well forget the whole diary, how easy.

Are you 7 years old?

The things I experienced were like stars in the sky, some of them moved me, some made me ashamed, some made me angry, some made me feel solemn and sacred, some made me feel funny, and some made me experience the joy of success. Now I'm going to tell you about one of my successes.

During my fifth-grade summer vacation, I watched people on the highway riding bicycles, and I didn't know how majestic it was. I was envious. I thought:

One day, I'm riding my bike down the street, I don't know how cool it is! Over time, this mentality of wanting to learn to ride slowly "blossomed and bore fruit" in my heart. Finally one day, I couldn't bear the loneliness in my heart and asked my cousin to teach me to ride, and under my repeated requests, my cousin had no choice but to follow me and take me to the park to learn to ride.

My cousin first rode the bike to a meadow and then said to me, "Riding a bike is actually very simple, as long as you hold on to the handlebars, push on it, and overcome your fear, that's it." You ride yourself first, and I'll hold the back seat.

It's great that I can finally learn to ride, and my heart is as sweet as honey. I held on to the handlebars and stepped onto the saddle, and I jumped straight in my heart like a rabbit, sometimes to the left, sometimes to the right, as if I would fall down if I wasn't careful. I tried my best to suppress my nervousness, calm myself down, and after a while, I mastered the art of balancing.

I thought to myself: riding is so simple, my cousin saw that I was riding so well, let go of his hand, I didn't pay attention, fell on all fours, I got up, I felt a pain, lifted the trouser tube to see, it turned out to be scratched, I really wanted to give up, don't learn. I poured my anger out on my cousin and yelled at him:

It's all your fault, why do you want to let go, causing me to fall so badly. "My cousin understood my feelings, and did not bother with me, and said to me; "Failure is the mother of success, who has not fallen when learning to ride a bicycle? Could it be that my cousin is a deserter, and I don't recognize this kind of cousin.

I'm not a deserter. "I'm on fire. I was a person who would not allow people to ridicule me, and I was determined that I must learn to ride no matter what.

Then you're not a deserter, just show me. My cousin said. "Wait and see.

I shouted at my cousin. I patted the dust off my body, rolled over into the car, and bravely pedaled forward, sitting in the car, I really regretted that I was so arrogant and unreasonable to my cousin, and blamed myself for being too proud and complacent. At this moment, a small pebble blocked the way in front of me, and I fell to the ground again.

But I didn't hesitate to stand up, step on the bike, no longer dare to be careless, and ride carefully. After falling and getting up again and again, it didn't take long for me to learn to ride.

The sun is always shining after the storm.

I'm not a brave kid. I'm scared.

With the passage of time, science and technology are also developing rapidly, and human beings have learned to clone, and if I can clone, I must clone a "healthy" earth.

In the 21st century, the number of human beings has increased dramatically; With the increase of motor vehicles and factories, the air is polluted, often causing sandstorms, acid rain and ......The atmosphere is destroyed, and the scorching sunlight hits the earth; trees are cut down uncontrollably; All kinds of resources, animals and plants in the world are on the verge of extinction ......These phenomena show that the earth has been destroyed beyond recognition by humans. When humans turn large areas of forests and farmlands into high-rise buildings, they do not know that natural hazards are approaching them.

Now I am working in an international research group. Today, I would like to present to you an idea that I have thought so hard about: cloning a "healthy" Earth. In the morning, I was worried about whether I could pass it, but now everyone applauded and passed unanimously.

With permission, our group started to get busy. Collect all kinds of resources on the earth, all kinds of basic materials needed to clone the earth, such as: water, soil, animals and plants, ......After a month of hard work, we have finally replicated a small earth, crystal clear, and this earth will have a longer life span in the future than the current earth.

We did a series of inspections, scans, calculations, measurements, ...... for the little earthThe structure of this new earth is exactly the same as that of the current earth. As the days passed, the new earth finally "grew up", and the scientific research team helped it to make a final check: the air was fresh, the temperature was suitable, the resources were abundant, the distribution was wide, and the flora and fauna were ......Conclusion:

Everything works fine. And then we send it into space. Most of the people on Earth today have moved to live on the New Earth.

High-rise buildings, parks, forests, ...... have appeared on the new earth

The woods suck up carbon dioxide and expel oxygen, allowing people to breathe fresh air and live longer. Nowadays, people are consciously protecting the environment. When we saw our results on the big screen, we all cheered.

The old earth has been deprived of its burdens, and it has slowly become the "health" it used to be. I looked at the "home" of the two humans and couldn't help but smile with relief.

I crave knowledge.

I crave knowledge, because knowledge is the wings to achieve my ideals. With knowledge, human beings have everything they have now.

Knowledge is the most indispensable thing in the human brain, Watt's steam engine, Bell's **, Edison's white lamp, Einstein's theory of relativity ......These are paved with a lot of knowledge, and knowledge is the bridge that connects all successes.

Knowledge should come from **? Knowledge is not just talking, it depends on a lot of accumulation, reading, time to have knowledge, the main way for our primary school students to acquire knowledge is to read more extracurricular books, the extracurricular books I am talking about here are not comics, but books that are beneficial to our primary school students, such as literature, biography, prose and so on. It's not enough to read more, but also to read good books.

Reading is not enough, we also need to combine theory with practice, practice is the ladder to achieve ideals, Lu You's poem wrote: The paper is shallow, and you must bow to it. Tell us that knowledge can only be applied appropriately under the premise of combining theory with practice, and it is not feasible to copy the theories on the books.

Now, we have to accumulate more knowledge, for the future useful, more knowledge, we can have more chances of success, everyone is familiar with Zhuge Liang, resourceful, many aspects of knowledge know, geography and astronomy are omniscient, the human situation is omniscient, which has a lot to do with his accumulation of knowledge in all aspects.

It doesn't hurt us to accumulate more knowledge, I desire to get knowledge, and knowledge can open the door to wisdom. Students, let's work together!

Today's society is like this, if you are not careful, you will fail. But don't forget to give yourself a round of applause when you're knocked out!

To applaud oneself is to encourage oneself.

Perhaps, you want to be the sun, but you are only a heart; Perhaps, you want to be a big tree, but you are only ordinary. As a result, you despair, lose your confidence, feel a little sad and a little lonely. Actually, failure.

Cheer for yourself, that is to prepare yourself for a new starting point.

In this world, there is no rule that anyone must applaud whom, so let's clap the applause for ourselves.

Applauding ourselves reflects our self-confidence and shows that we don't need to look for ourselves in the affirmation of others: applauding ourselves expresses our ambition for ourselves and means that we can reach the ultimate of our ideals.

We need to applaud, we should applaud ourselves, and we should not be discouraged and discouraged because we often encounter setbacks. It is necessary for us to applaud ourselves and have reason to rejoice in ourselves.

Once frustrated, the understanding of life deepens a layer; If you make a mistake once, you will add a level to your understanding of life; Tribulation once, the connotation of success is thorough. So, we must applaud ourselves. The applause of others drifts to the clouds in the sky, bringing you nectar and joy.

Your own cheers are like a source gushing out from the earth, nourishing your heart.
