Primary school fourth grade Olympic theme essay 2008 Olympic Games held in Beijing, the five lovely mascot Fuwa stood in the main stadium "Bird's Nest" at the door, they are welcoming people from all over the world.
Beibei, Jingjing, Huanhuan, Yingying, Nini, their names and together is "Beijing welcomes you", see, this is Beijing's invitation to the world's people! Bei Bei introduced to everyone and said: "I come from rivers, lakes and seas, representing prosperity and symbolizing world peace! "My original form is a giant panda, I am a national treasure of China! I'm friendly and warm!" Jingjing went on. Huanhuan jumped in and said, "My original form is the Olympic flame, I represent passion!" Yingying also said: "I come from the vast western land of China, I will spread the good wishes to the world, I am also the symbol of the Green Olympics ......" Before the words fell out of her mouth, three people in green uniforms walked up quickly, interrupting Yingying's words. Beijing can't host the Olympics yet, and 'Green Olympics' is the theme spirit of this Olympics! But look, can Beijing fulfill the requirements of the Green Olympics?" With that, they raised the report in their hands, "Here are the photos we took!" It turns out that these three people are actually the Olympic Committee sent environmental protection messengers, their hands of photos showing Beijing encountered a sandstorm when the earth-colored sky, as well as gusty winds swept up the yellow sand and dust, as well as people wearing hats, masks in the wind difficult to walk in the scene.
The data above the report is even more alarming: on the afternoon of March 15, 2002, the sandstorm struck Beijing, lasting 49 hours, with a distribution height of about 3,500 meters; on March 20, it struck Beijing for the second time and lasted 51 hours, with respirable particles in the air amounting to 1. 10,000 milligrams per cubic meter, which is dozens of times the national standard, and the total sedimentation amounted to 30,000 tons, with a per capita of 30,000 tons in Beijing. amounted to 30,000 tons, Beijing per capita amounted to 3 kg.
In the face of everything in front of us, the original jubilant stadium suddenly quieted down, only to hear the environmental messenger announced: "China can not host the Olympic Games at present." "No! How can this be?" I broke out in a cold sweat and sat up, fortunately it was just a dream! However, after waking up from the dream, should we not also reflect on it? Now, the sandstorm is still a serious weather disaster in the north of China, just this year's March 27, Beijing once again experienced a sandstorm attack, the respirable particulate matter index in the air reached 346 micrograms per cubic meter, which is this year's Beijing appeared in another heavily polluted weather.
Wind and sand not only affect our travel and health, but also seriously affect the cleanliness of the urban environment! Hosting the Olympic Games is a hundred-year dream of the Chinese people. To do a good job of the Olympic Games, is our Beijing people and the whole country people **** the same responsibility.
So, I think we must start from ourselves, to contribute to the protection of the environment their own modest contribution. For example, we can enthusiastically participate in the spring planting activities, usually pay attention to the care of flowers and trees, do not spit, do not litter, and strive to protect the environment in which we live.
After our unremitting efforts, the 2008 Olympic Games will be an environmentally friendly Olympics, by then we will see more trees, flowers more colorful and beautiful, the river is more green and clear, and even the sky is blue as a wash! Let us organize the Green Olympics under the blue water and blue sky, to meet the friends from the five continents with a beautiful environment.

My discovery
In the fourth grade, once in the nature class, the teacher told us that paper can be used as a pot to boil water. When I heard it, I thought the teacher's words were ridiculous: how could paper be used as a pot? The water is not yet hot, the paper will not be burned first? But the teacher looked serious, not like lying to us. So I went home from school to do experiments, want to confirm the results.
I went to the coal room to find a wire, with tongs to clamp the wire into a small shelf, and then find a piece of paper, folded into a "small water basin", filled with water, placed on the shelf, and then find a candle, placed under the shelf, and finally I lit the candle. I stared at the water in the "water basin": two minutes passed, and the bottom of the "water basin" had been blackened. After two minutes, the water was already a little bit hot. After another two minutes, a miracle happened - the water boiled! The paper didn't break! I do not believe their eyes, and checked a few times, the paper is still not broken!
The success of this experiment made my curiosity more intense, what is the reason? Why does the paper not break? I decided to figure out the mystery! I came to the school library to check the information, and finally found the answer: the original is the temperature at play! Because the temperature needed to burn paper is 130 degrees, while the water as long as 100 degrees, so the heat is all absorbed by the water, of course, the paper will not burn up!
This experiment confirms that some things that seem strange to you will not seem strange if you try to find the answer!
6. to life as the theme of the essay sample, the content of the fourth grade
Suddenly the power went out, the surroundings fell into darkness, I do not know what to do panicked, and suddenly remembered a cup-shaped small scented candles that I bought for my birthday. So I took it out and lit it on fire.
Staring at its faint light, it occurred to me that in such a brightly-lit age, it no longer seemed useful. I never seemed to pay attention to the candle, but only used it as a wish for my birthday. But now, this long neglected thing has become important again, and the insignificant light of the candle has also turned my uneasy mood into calmness at this moment. The lilies on the table were casting their shadows on the wall so clearly by the candlelight. All at once, I saw the candle diminishing a little, and everything around me seemed to be warmed up in this winter day. I realized that the candle was also a life, and had a characteristic that life has - love. Candle's love will not be like candy to make you sweet to the bottom of your heart, not like a light song to make you forget the pain, and not like the blue sky to make you happy to laugh out loud. All it can do is to give you a ray of light in the darkness and a little warmth in the cold. Light and warmth are insignificant in the eyes of some people.
But I know, it is in its whole life to dedicate, to love every even does not care about it living beings. Candle has love, there is nothing to be said, but you can not forget, when the candle to the whole life of love are dedicated to you, it has nothing to ask, nothing to complain. Yes, it shed tears, but they are not tears of remorse, not tears of complaint, but tears of walking through life with no regrets, tears with a smile, that is, it has given to others, love others traces.
Candlelight is still swaying, the shadow of the lilies on the wall seems to be clearer, and the fragrance of the lilies fills the warmth.
When the call came, the light came on, but I couldn't bear to put the candle out, so I turned the light off, and there was only the candlelight left again, and I saw the real life, the real love, and the real beauty again.
7. Primary school fourth grade theme of environmental protection and energy saving essay
Environmental protection essay - saving limited resources Everyone living in this world should know.
In the past, the earth was green, the sky and the sea were azure, birds flew freely in the sky, fish swam happily in the water, other animals ran happily on land, people helped each other `````` The whole earth presented a harmonious scene. Mother Earth also smiled sweetly.
But now, the Earth has changed. Green a lot less, while the yellow is more and more, the earth this is what happened? This is not because people cut down a lot of trees, this behavior not only makes the birds do not have a home to live on, but also caused a large area of collapse, floods and so on.
Without trees, our planet seems to have lost a balance frame. Moreover, cans are now sold in every store, and cans are even more of a pollution.
The road and the school have become their "home". The cans are also made of aluminum, which is harmful to the human body.
Besides, it takes a lot of process to make such a cup of cola, which wastes a lot of resources. Old batteries are even more harmful.
Once mixed with household garbage, under certain conditions, a series of chemical reflections will occur, releasing toxins, affecting people's bodies and destroying the ecological environment. Now people's technology is developed, the factory in order to improve efficiency, even the river as a good place to discharge sewage, the river made dirty, strange odor, more hateful is our mother river Yellow River is also polluted, the Yangtze River is even more serious, the garbage everywhere, so that pedestrians cover their mouths and quickly walk past.
So, we have to prove with actual labor. For example, saving water.
Such as: turn off the faucet in time after using the water; use the water for washing vegetables to water flowers, shabu-shabu mops, and flush toilets. Don't think that a few drops of water from the faucet is nothing.
A faucet dripping one drop of water per second, a year is a waste of 36 square meters of water. If a family saves water every month, how much water will the country save in a month? Fortunately, people have realized the seriousness of the pollution of the earth, we have acted together to protect our home.
But I also hope that those who did not move to act, bend down, pick up the ground a piece of paper, a piece of fruit peel, so that our tomorrow is better, more beautiful! I believe that as long as we all work hard, it is not impossible to make the earth return to the way it was hundreds of years ago! Second Protect the Earth, start from me Throughout the ages, Mother Earth has nurtured countless generations of children and grandchildren with her sweet milk. The original she was adorned by the younger generation.
But now humans are torturing her for their own benefit. Humans have only one Earth; and the Earth is facing a serious environmental crisis.
"Save the Earth" has become the strongest cry of the people of the world. I am heartbroken by the deterioration of the surrounding environment, and I think: as the future successor of the youth, if we do not understand the composition of the human environment and the seriousness of the environmental problems, ignore the laws and regulations relating to environmental protection, do not enhance the awareness of environmental protection, and consciously fulfill the obligation to protect the environment, then our lives will be destroyed in our own hands, and the Lord will impose severe punishment on us.
In this regard, I am determined to start from me to care for the environment, to protect our home, which depends on the survival of the environment, to be a guardian of the protection of the environment. In the past year, I actively participate in the school's tree-planting activities, led our first year (6) squadron class cadres created a "Green Angel" green planting team, encouraging players to adopt a sapling in the campus, using the after-school hours to dress it up, and laying the foundation for it to grow into a big tree.
In the school's "Let the Earth full of vitality" signing activities, I solemnly signed my name on it, and wrote down his determination and expectations of environmental protection, the vision of a better future. I actively participate in the school in the World Environment Day held by the prize essay, seriously access, collect all kinds of information, social research, write about the environmental management of the vision of the article, I often go to the school to participate in the organization of environmental protection lectures, watch environmental protection aspects of the video, and actively participate in the environmental protection of the knowledge of the question and answer survey activities, seriously fill out each question.
I participated in the "red scarf planting green team" website construction, in which a large number of environmental pictures and environmental protection knowledge, as well as environmental protection of all aspects of the legal knowledge, China's environmental protection in the development of trends, environmental protection in countries around the world; every month I use the Internet, newspapers, find some of the latest Every month I use the Internet, newspapers, to find some of the latest topics and boards "environmental information" to tell everyone; also regularly produce some publicity boards to publicize environmental protection knowledge and life in the environmental protection of common sense. Raise the awareness of environmental protection; call on students from different aspects to care for their homes, from the small things around us, for the surrounding environment to dedicate their own strength! I actively mobilize people around me to come together in accordance with the law to protect and build human **** have the same and only home, in order to promote the sustainable development of the economy and society, and contribute to the civilization of mankind.
I also and my classmates *** with the launch of the "raise a pot of flowers, adopt a tree, cherish every piece of green space, so that we are surrounded by green" and "small plastic bags do not use foam lunch boxes and disposable chopsticks, so that we away from white pollution" initiative. Initiative. Let's put down the convenient bag, pick up the food basket, let us **** with the beautiful green tomorrow, towards a brilliant, brilliant future! According to a report I gathered: "Environmental problems are caused by mankind's irrational development and utilization of natural sources.
Touching environmental problems are mainly air pollution, water pollution, noise pollution, food pollution, inappropriate development and utilization of natural resources these five categories." One by one, the iron-like facts tell us that they relentlessly devour human life like a demon.
It threatens the ecological balance, jeopardizes human health, and restricts the sustainable development of the economy and society, and it puts mankind in a difficult situation. For this reason, I make a declaration: "As long as we - human beings have always never forget to protect the environment consciousness, there is a law to govern the environment consciousness, the global village will become a beautiful paradise."
The future sky must be turquoise blue, the water is clear, green trees and flowers everywhere, human beings can enjoy the happiness given to us by nature. "The true test of our contribution to the environment is not words, but actions."
Although I am doing nothing more than a few small things, I firmly believe that if we all have a sense of responsibility to protect the environment, starting from ourselves.
