2. The theme of the small composition in the fourth grade of primary school

Xia Yu

It often rains in summer. After a hot and dry day, a sudden rain and a sudden temperature difference just want us to think of two words, happy!

It is often said that "spring rain is as moist as oil". Yes, spring rain is precious, so summer rain comes and goes like a little girl's tears. Without any warning, it seems that one moment it was a happy smiling face, and the next moment it is like tears pouring out, releasing all grievances.

Summer rain is lively. Water drops fell to the ground, chasing one after another like a broken bead. In less than half an hour, the rain curtain was formed and there was a small ditch on the ground. Although the two opposite windows are very close, because of the shelter of the rain curtain, it gives people a hazy feeling, which makes people enter a fairyland and indulge in it.

Summer rain is gentle. Like her mother, she touched the earth with both hands, looked at every corner with loving eyes, watered plants, nurtured animals, washed hillsides, filtered the air, and brought abundant vitality to the earth.

Summer rain is beating. Like a silver guqin, a raindrop is like every string on the guqin. A gentle touch will make a moving sound. Shh, listen carefully. Each string is different from each other. Their voices and the notes in the music are beating. It is precisely because of these different notes that colorful movements are formed. This makes our nature colorful.

Oh! Xia Yu, you are so beautiful and lovely. With you, my life is no longer monotonous.

The 2008 Olympic Games was held in Beijing. Five lovely lucky fuwa stand at the gate of the main gymnasium "Bird's Nest". They welcome people from all over the world.

Beibei, Jingjing, Huanhuan, Yingying and Nini, their names together are "Welcome to Beijing". Look, this is Beijing's kind invitation to the people of the world! Beibei said to everyone: "I come from rivers, lakes and seas, representing prosperity and symbolizing world peace!" "My prototype is the giant panda, and I am the national treasure of China! I am friendly and enthusiastic! " Jingjing continued. Huanhuan rushed to say, "My prototype is the Olympic flame, and I represent passion!" " "Yingying said not to be outdone:" I come from the vast western land of China, and I want to spread my best wishes to the world. I am also a symbol of the green Olympics ... "After that, three people in green uniforms quickly came forward and interrupted Yingying's words:" Beijing can't host the Olympic Games yet, but' green Olympics' is the theme spirit of this Olympic Games! But look, can Beijing meet the requirements of an environmentally friendly Olympics? "As they spoke, they held up their reports." This is the photo we took! "It turns out that these three are environmental ambassadors sent by the Olympic Committee. The photos in their hands show the yellow sky, yellow sand and floating dust rolled up by strong winds when Beijing was hit by sandstorms, and people wearing hats and masks struggled to walk in the wind.

The data in the report is even more shocking: on the afternoon of March 15, 2002, a sandstorm hit Beijing for 49 hours, with a distribution height of about 3,500 meters; The second attack on Beijing on March 20th lasted for 5 1 hour, in which the inhalable particles in the air reached 1. 10000mg/m3, dozens of times the national standard, with a total settlement of 30,000 tons and a per capita of 3 kg in Beijing.

Facing everything in front of us, the stadium, which was originally jubilant, suddenly quieted down, only to hear the environmental messenger announce: "China can't host the Olympic Games yet." "no! How did this happen? " I broke out in a cold sweat and sat up Fortunately, it was just a dream! However, after waking up, should we also reflect? At present, sandstorm is still a serious weather disaster in northern China. On March 27 this year, Beijing was hit by a sandstorm again, and the index of inhalable particulate matter in the air reached 346 micrograms per cubic meter, which was another heavily polluted weather in Beijing this year.

Sandstorm not only affects our travel and health, but also seriously affects the cleanliness of the urban environment! Hosting the Olympic Games is a century-old dream of China people. It is the common responsibility of us Beijingers and the people of the whole country to run the Olympic Games well.

Therefore, I think we must start from ourselves and make our own contribution to protecting the environment. For example, we can take an active part in planting trees and grass in spring, take good care of flowers and trees at ordinary times, do not spit or litter, and strive to protect our living environment.

Through our unremitting efforts, the 2008 Olympic Games will be an environmentally friendly Olympic Games. By then, we will see more trees, more beautiful flowers, greener rivers and even blue sky! Let's hold a green Olympics under clear water and blue sky, and welcome friends from five continents with beautiful environment.

4. What is the theme of the fourth grade composition?

The story of me and small animals

When I was a child, I liked small animals very much. I always cherish the rabbits my mother bought for me, but every time I die within a few days. I was very sad at that time. Why does my rabbit die every time? Maybe I was too young or didn't know how to raise small animals, so my mother threw away the dead rabbit. I really wanted to cry at that time, but I endured it. I thought to myself, if

When I was 5 years old, my mother and I found a lovely white cat on the road. It was dirty at that time, but I didn't dislike it, because when I was a child, I said I would raise small animals, no matter what! I have washed Mimi since I brought her home. I told my parents not to dislike the poor kitten, but the kitten didn't listen every time. My father saw the kitten urinating everywhere and biting clothes and slippers several times, but I always took Mimi back from the park and raised her at home, and she didn't arrive for a month. When I came back from school, Mimi had been lost. I cried at that time. I cherish Mimi very much. Why?

Another year passed and someone gave me a dog. My name is hello. That's a Beijing pug. It's dark. The original owner was very kind to it. Because I was going abroad, I didn't have it, so I gave it to me. I want to bring it up seriously. I left all the quilt covers, bath towels, urinals and towels that my original owner gave me in my room. But a few days later my mother gave them to her friends. I still have to study. But I have given up the idea of having a dog, because my mother always gives my beloved dog to others when I have a dog. I know what my mother thinks, and she wants me to study hard and not concentrate on raising dogs. This will delay my study, but I really want to try having a dog. Now that I have grown up, I won't keep dead dogs, but my mother won't listen. Until last year, I found another cat, which looked like an overbearing cat. My mother seems to like this cat, too. She always walks around with Mimi and sometimes plays with Mimi, but in the end she doesn't know where she went. She went to play with other cats, and I never saw my boobs again. If I had a dog, I would take good care of it! !

5. About the composition of My Discovery in Grade Four, if any, please upload the theme.

My discovery

In the fourth grade, in a science class, the teacher told us that paper can be used as a pot to boil water. After listening to it, I thought the teacher's words were ridiculous: how can paper be used as a pot? Didn't the paper burn before the water was hot? But the teacher is serious, not like lying to us. So I came home from school to do experiments to confirm the results.

I went to the coal house to find a wire, clamped it on a small shelf with pliers, then found a piece of paper, folded it into a "small basin", filled it with water, put it on the shelf, then found a candle, put it under the shelf, and finally I lit it. I stared at the water in the basin: two minutes later, the bottom of the basin was dark. After two minutes, the water was a little hot. Two minutes later, a miracle happened-the water boiled! The paper is not broken! I can't believe my eyes. I checked several times, but the paper still didn't break!

The success of this experiment has strengthened my curiosity. What is the reason? Why won't the paper break? I decided to find out! I came to the school library to check the information and finally found the answer: it turned out that the temperature was at work! Because the temperature required for paper to burn is 130 degrees, and water only needs 100 degrees, so the heat is completely absorbed by water, and the paper certainly can't burn!

This experiment proves that some things that seem strange to you will not be strange as long as you try to find the answer!

6. Life-oriented composition mode, the content of the fourth grade of primary school.

Suddenly, the power went out and everything was in darkness. I was at a loss, and suddenly remembered a small cup-shaped candle I bought for my birthday. So I took it out and lit it.

Staring at its faint light, it suddenly occurred to me that it seemed useless in such a bright era. I never seem to notice the candle, but I just take it as a wish for my birthday. Now, what I have neglected for a long time is important again. At this moment, the insignificant light of the candle made my uneasy mood calm. The lilies on the table were clearly projected on the wall by candlelight. Suddenly, I saw fewer candles. In this winter, everything around me seems to be getting warmer. I realized that this candle is actually a life, and it also has the characteristics of life-love. Candle love will not make you sweet to the bottom of your heart like candy, nor will it make you forget your pain like a light song, nor will it make you laugh like a blue sky. All it can do is give you a ray of light in the dark and a little warmth in the cold. Light and warmth are insignificant in some people's eyes.

But I know that it is dedicating its life to love every living thing, even if it doesn't care. Candles have love, there is nothing worth noting, but you can't forget that when candles give you the love of their lives, they ask for nothing and have no complaints. Yes, it shed tears, but not tears of regret and complaint, but tears of regret and smile, that is, it once gave others and loved others.

The candlelight is still swaying, the shadow of lily on the wall seems clearer, and the fragrance of lily is filled with warmth.

After the electricity was turned on, the light came on, but I couldn't bear to put out the candle, so I turned it off, leaving only candlelight. I saw real life again, real love, real beauty.

7. Composition with the theme of environmental protection and energy saving in the fourth grade of primary school

Environmental protection essay-saving limited resources Everyone lives in this world and should know it.

In the past, the earth was green, the sky and the sea were blue, birds flew freely in the sky, fish swam happily in the water, other animals ran happily on the land, and people helped each other. The whole earth presents a harmonious scene. Mother Earth also smiled sweetly.

But now, the earth has changed. Green is greatly reduced, but yellow is more and more. What happened to the earth? It's not just a lot of people cutting down trees. This behavior not only makes birds homeless, but also causes large-scale collapse and flood.

Without trees, our earth seems to have lost a balanced framework. And now all the shops are selling cans, which is a kind of pollution.

Roads and schools have become their "homes". Also, cans are made of aluminum, which is also harmful to people's health.

Besides, making such a coke requires many processes and wastes a lot of resources. Old batteries are more harmful.

Once mixed with domestic waste, under certain conditions, it will produce a series of chemical reactions, release toxins, affect human health and destroy the ecological environment. Now people's science and technology are developed. In order to improve efficiency, the factory regards the river as a good place to discharge sewage, making it dirty and smelly. What is even more hateful is that our mother river, the Yellow River, is also polluted, and the Yangtze River is more serious, with garbage everywhere, and passers-by cover their mouths and go.

Therefore, it should be proved by actual labor. Such as saving water.

For example, turn off the faucet in time after running out of water; Water the flowers with vegetable washing water, rinse the mop and flush the toilet. Don't think that a few drops of water in the tap are nothing.

A drop of water from the tap every second is 36 cubic meters of water a year. If a household saves one side of water every month, how much water does the whole country save in one month? Fortunately, people have realized the seriousness of the pollution on the earth, and everyone has taken action to protect our home together.

But I also hope that those who are unmoved will take action and bend down to pick up a piece of paper and a piece of peel on the ground to make our tomorrow better! I believe that as long as we all work hard, it is not impossible for the earth to return to the way it was hundreds of years ago! Second, protect the earth. Since I started, Mother Earth has raised countless generations of children and grandchildren with sweet milk. It turned out that she was beautifully decorated by junior students.

However, now human beings have tortured her to death for their own interests. There is only one earth for mankind; The earth is facing a serious environmental crisis.

"Save the Earth" has become the strongest voice of people all over the world. I feel heartache for the deterioration of the surrounding environment. I think: if teenagers, as future successors, don't understand the composition of human environment and the seriousness of environmental problems, ignore the laws and regulations on environmental protection, don't enhance their awareness of environmental protection, and don't consciously fulfill their obligations to protect the environment, our lives will be destroyed in their own hands, and God will severely punish us.

To this end, I am determined to start from myself, protect the environment, protect our homeland and be a guardian of the environment. In the past year, I actively participated in the tree planting activities carried out by the school, led the class cadres of our Senior One (6) Squadron to set up a "Green Angel" tree planting and green protection group, encouraged the team members to adopt a small sapling on campus, and used their spare time to decorate it carefully, laying the foundation for it to grow into a towering tree.

In the signature activity of "Let the Earth Be Full of Life" organized by the school, I solemnly signed my name on it, writing down my determination and expectation for environmental protection and my vision for a better future. I actively participated in the prize-winning essay-writing activities held by the school in World Environment Day, carefully consulted and collected various materials, conducted social surveys, and wrote articles on environmental governance. I often take part in environmental protection lectures organized by the school, watch environmental protection videos, actively participate in environmental protection knowledge quiz activities, and fill in each question carefully.

I participated in the website construction of "Green Team with Red Scarf", and posted many pictures and knowledge about environmental protection, as well as legal knowledge about various aspects of environmental protection, the development trend of environmental protection in China, and the environmental protection situation around the world. Every month, I will use the internet and newspapers to find some latest "environmental information" with different themes and sections to tell you; We also make some publicity boards regularly to publicize environmental protection knowledge and common sense of life. Raise everyone's awareness of environmental protection; Call on students to take care of their homes from different aspects, start from the little things around them and make contributions to the surrounding environment! I actively mobilize people around me to protect and build the same and only home of mankind according to law, promote the sustainable development of economy and society, and make contributions to human civilization.

Together with my classmates, I also launched the initiative of "raising a potted flower, adopting a tree, cherishing every green space and making our surroundings full of green" and "replacing foam lunch boxes and disposable chopsticks with small plastic bags to keep us away from white pollution". Let's put down the convenient bag and pick up the vegetable basket. Let's move towards a bright green tomorrow and a brilliant future! According to a report I collected, "environmental problems are caused by unreasonable development and utilization of natural resources by human beings."

Shocking environmental problems mainly include air pollution, water pollution, noise pollution, food pollution and improper development and utilization of natural resources. "Iron facts tell us that they are ruthlessly devouring human life like demons.

It threatens the ecological balance, harms human health, restricts the sustainable development of economy and society, and puts human beings in a dilemma. To this end, I issued a declaration: "As long as we humans always have the awareness of protecting the environment and managing the environment according to law, the global village will become a beautiful paradise".

In the future, the sky will be blue, the water will be clear, the trees will be shaded, and the flowers will be everywhere. Humans can enjoy the happiness endowed by nature. "The real test of our contribution to the environment is not words, but actions."

Although what I am doing now is only a small thing, I firmly believe that if we all have the responsibility to protect the environment, we should start from ourselves.

8. Six fourth-grade compositions

Goldfish There are eight goldfish in my fish tank.

Three people seem to have been splashed with ink, and they are all black; A silver coat from beginning to end, sparkling; The last four are all red and radiant. Although it is usually elegant, it is completely different when eating.

No, whitebait is walking on the catwalk, but as soon as I spilled fish food, it immediately became red-eyed, rushed into the fish food like the wind, and sucked up a small part of the fish food like a vacuum cleaner. At this time, grandpa three and his wife four rushed up and took the rest of the fish food.

After eating, they will dance in groups to thank me! They are very naughty. Look, there are their abstract paintings on the floor again. Alas, every family has its own problems.

It's nothing, but when they were shivering on me looking for a coat, they still stubbornly threw a few drops of "ice water" on me, which made me feel cold. It's really eight naughty bags. Don't play tricks. I went to feed them a few days ago and found eight goldfish floating on the water, lying motionless on the water. I quickly fished it up by hand. I didn't expect these eight goldfish to come back to life, scrambling to eat fish food, which made me very angry. How dare you lie to me? You're dead.

When my eyes were burning and my teeth were gnashing, eight goldfish danced together again. I immediately turned anger into joy and absorbed in their dance ... whitebait is going to be a mother, and I hope it can give birth to many lovely baby fish to shout for the birds. Today, a new street manager came to this town. As soon as he took office, he said to the cleaner, "Clean everything in the street, and there can be no obstacles on both sides."

The workers did as the manager told them. They first cut down the trees on both sides and pulled up the grass, leaving no one behind. Everyone worked happily, and no one thought of the consequences. In just one winter, the obstacles on the street and on both sides were removed and the whole street was widened.

When winter goes and spring comes, a flock of birds fly back from the south to the place where they once lived. The birds were surprised: "Hey! What about the original tree? What about the small home we once built? " They looked around, even the lawn that had been chasing and playing with friends disappeared, and it was replaced by a wide asphalt road. The car passed by, splashing suffocating smoke.

The birds just remembered to fly when suddenly a big net fell off the mask. Then I heard a child shout happily: "I caught it, I caught it, you see, there are always more than a dozen, enough for our little baby to eat for a few days."

Before dying, a captured bird said, "Dear human beings, everyone says that we are good friends. Is this how you treat your friends? " ? Oh, my God! It doesn't matter if I die. I must give my surviving brother a home! "Snail catching In the afternoon, my mother, uncle kitten, my aunt and my brother went to Zhu Youxi to catch snails. Although my brother and I are both novices on the road, we caught three in one hand and soon packed half a bag. And our "rivals" mother and little aunt are already "veterans with more than six years' work experience", and they have caught a bunch of them, except for a little fake gold, all of them are "glittering".

We met, which was an eye-opener. Later, we mastered the "secret" and "improved our ability" and caught 10 in one hand, while our "opponent" caught five bags earlier, and we only packed three bags. In order not to be surpassed, we used all the "secrets", and finally, we won the opponent with a bag and a half advantages. My hobby is collecting pebbles. Actually, I have a little story about collecting pebbles! I remember one day, my mother and I went to a small park to play. There is a path paved with pebbles. It's comfortable to walk on it. I accidentally kicked a stone. I picked it up and put it in my hand. The weather is cool and humid. Touch it with your hands. It's round and slippery. I asked my mother, "why are pebbles round and so smooth?" Mother said,' Because pebbles have been soaked in water for a long time, they have been washed away by the current.

""oh " I nodded my head.

Since then, I have been fascinated by pebbles. Whenever I see them, I can't put them down. I put them all in a small box. They all have a nice name: Moonstone, the most gorgeous ... but something unexpected happened. One day, when I came home from school, I opened the small box and saw that there was only moonstone in it. I rubbed my eyes hard and couldn't believe it was true. Take up more space! "Mom said, I was so angry that I could not speak. I ran into the house and cried. Despite the storm, I still collect pebbles to watch the rain. On Saturday, I was watching TV alone at home when I suddenly heard thunder outside. I think it will rain. I quickly got up and closed the window, only to see a flash of lightning across the sky outside the window, illuminating the earth.

Then there was a muffled thunder in the distant sky. At that moment, the image of the earth became a fairy tale world.

Leaves whistling in the wind, raindrops dancing happily with the accompaniment of music. This scene is like a magical band playing, more like the animal kingdom holding a cool summer dance. I didn't expect rain to be so interesting.

Everything in nature is beautiful. Students, let's try our best to experience and discover. Family knowledge contest "National Day" has just passed. Students, how did you spend it? To tell the truth, I had a meaningful holiday, because our family held a "family knowledge contest" and I volunteered to be a small host! I prepared a topic, imitated the appearance of Sister Moon on the children's channel, and said with a smile, "The family knowledge contest begins now! Let my mother answer: What is the oldest writing in China? " Mother pondered for a while and replied, "This is Oracle Bone Inscriptions of the Shang Dynasty."

"Exactly, plus 10." After a pause, I asked another question; "Please ask Dad to answer: A school is divided into two yards, and there are many students in one yard.

Too little, too little. (type a mathematical operation tool). "

After reading the question, I looked up at my father and confused him. My father thought about it, but he didn't.

9. The second volume of grade four exercises the composition of the symposium on hygiene.

In recent years, a sudden epidemic has disrupted people's normal life. In order to make students more aware of the dangers of "three no food", Mr. Mao held a class discussion in Chinese class, and everyone raised their hands to express their views on the theme of "three no food".

Some students introduced the harm of "three no foods" to human body, and some students introduced the production process of "three no foods"; Some students introduced some ingredients in the "three no foods"; Some students introduced what diseases "three no foods" will get if they are eaten in the human body. . . . . .

Yang Rui said: "These" three no foods "have no production date, no hygiene certificate and no license. These three are indispensable. "

Wang said: "I want to learn how to stop eating' three no foods' from the Internet."

Ma Jun said, "Teachers should send text messages to our parents so that they can supervise their children."

Liu Xiaotong said, "My aunt is a doctor. I can write him a letter and ask him to come to school to teach us how to identify these "three no foods". "

At the end of the seminar, Mr. Mao said, "You spoke very well. We must put an end to eating "three no foods". Don't just talk and not practice! "

Through this seminar, I was deeply inspired by what I will do in the future:

1. You can't eat "three no foods".

2. To identify "three no food".

3. Understand the harm of eating "three no foods" to human body.
