Earth Crisis Composition121In the 20th century, human science and technology advanced by leaps and bounds. It is not surprising to go to the moon, to Mars, or even to live on Mars for two or three days. In 20xx, I became a professor at China Institute of Astronomy. At 20: 35 on February 8th, 20xx, I was observing Mars with the detector on the light speed telescope. When I moved the telescope to other places, I found a comet running at one third of the speed of the universe. I'm beginning to wonder. I walked to the front of the astronomical radar screen and searched his orbit carefully. According to the screen, this meteorite contains many unknown powerful emission elements and a large number of atoms. It's incredible!
After a while, I found an amazing fact. The orbit of this meteorite actually goes straight to the earth. Oh, no, if this situation continues, half the earth may be destroyed in less than 24 hours! So, I immediately boarded the sonic hovercraft and rushed to the United Nations Institute of Astronomy. I arrived at the school gate in less than five minutes. I hurried into the dean's office and reported the earth-shattering news to him. The dean was surprised and immediately called the important personnel of the college to the conference room.
Professor Zhang, honorary professor of the college, Dr. Chen, who has rich astronomical knowledge, and other faculty members attended the meeting. "I called everyone to the meeting this time, mainly because I have a message to tell you." The dean told everyone about it in detail. "I wonder if you have any countermeasures to deal with this disaster?" Dr. Chen said eagerly: "We can use a nuclear cannon to fire shells at the earth, so that this comet will be shattered at a distance of 15 trillion kilometers from the earth." Isn't that all right? " I said calmly, "It's too late. Now he is less than 5 million kilometers away from the earth. His broken meteorites are enough to pass through the atmosphere and give the earth a serious blow. " Professor Zhang said unhurriedly, "In fact, I recently invented a kind of light energy laser beam, which can completely smash this massive comet without any harm to the earth, but she is still in the experimental stage ..." "Never mind, this is the last hope!" Everyone said firmly.
So after unanimous agreement, we came to the astronomical turret. After more than an hour of adjustment, the ju pao finally entered the state and was ready to launch a beam. "0 1 console ready, 023 launch pad ready, 056 adjustment platform ready, 3, 2, 1, launch!" With a loud noise and slight vibration, the recovery that threatened life on earth disappeared into outer space. Seeing this scene, all the staff cheered loudly: "Long live the earth! ..... "The earth crisis is thus solved.
Earth Crisis Composition 23198 65438+February 3, this day, nothing special, everything is calm. When the weather is fine, people go to school, work, exercise and play as usual. As everyone knows, the danger is coming quietly.
3198165438+1On the evening of October 4, the unmanned space exploration spacecraft "Bright Exploration" decided by the United Nations and assisted by various countries will be launched. The announcer is counting down to the world: "Ten, nine, eight, three, two, one, light the fire! Launch! " The spaceship soared into the sky like a rising star in Ran Ran, Ran Ran. Suddenly, the speed of the spacecraft increased rapidly and disappeared into space in the blink of an eye. In the main command room, Dr. Jin dropped the teacup on the ground and beat the table angrily. He said to his servant, "Damn it! Who did this? ! What's going on! " "Report, the final data sent back by the spacecraft shows that there is a strong gravity to suck the spacecraft away." "What planet is it?" "I haven't found it yet." As there is no landing, this matter can only go away like this.
Back to now, the sky is surrounded by sudden dark clouds. When the clouds cleared, I saw a huge planet appear in the sky. It absorbs everything on the earth, uproots buildings and foundations from the concrete floor, and sucks up trees, flowers and cars. The whole world is in a panic, scrambling to run deep underground.
At this moment, Dr. Jin and others in the underground laboratory are worried. The gravity of that planet is four times that of the earth. It will suck away everything on the earth and make the earth its satellite. When an astronaut named Carl volunteered to solve the crisis for the earth and all mankind, Dr. King was considering a solution. Dr. King asked him to talk about the plan. He said, "I think maybe we can use its great gravity. Dr. Hull has just invented a protective suit that can get rid of gravity. Maybe I can sit on the spaceship with it and suck it up by its attraction, and I can walk on it in protective clothing without gravity. I buried two super nuclear bombs on the planet and blew them up after detonation. " "However, I have studied that under such a large gravity, protective clothing can only last for three minutes. How can you get away with it?" "Doctor, we can only bet once!" "good! You can only bet once! Act now, I'll go with you. " Dr. King said firmly.
Soon, a spaceship flew out of the underground base and was sucked to the planet. Dr. King and Carl boarded the planet in anti-gravity protective clothing. "good!" People in the operating room are cheering. I saw two people drilling the ground with a laser. Unexpectedly, they got stuck. Everyone is sweating for them, and their hearts are in their throats. Time is running out! Dr. King and others drilled in another place, and finally succeeded! A nuclear warhead was buried, and at this time, the two men were attracted by huge gravity, and the protective clothing failed. "What should I do?" Dr. King glanced at Carl, who nodded firmly. He pressed the button quickly. After the huge explosion, the crisis of the earth was lifted and mankind was saved. But the people in the command room are very heavy.
Since then, people spontaneously commemorate these two heroes, Dr. King and Carl, on February 3, 65438 every year.
Due to the vast land area and ocean area of the earth, fresh water resources are insufficient. China is listed as one of the top ten water-deficient countries. If people no longer cherish water, then people will only face the road to extinction! In addition, due to people's excessive reclamation of land, groundwater has dropped sharply and land has declined. Let's make an agreement for water resources together! Tomorrow will be better!
Overexploitation will only backfire.
"Dong! Hey! " "The mudslide is coming!" People shouted. Soon, the mudslide washed down the house! This is the earth crying. Due to people's over-exploitation, trees are cut down, which destroys the environment, cracks the mountain and forms mudslides. As a result, the mudslide washed away people's homes.
Every move of a person may be related to his future. For example, people litter, resulting in the destruction of the ozone layer and holes in the Antarctic sky. Ultraviolet rays hit the Antarctic ice sheet directly. The Antarctic ice sheet covers an area of 6.5438+0.398 million square kilometers, with the thickest point of 4,200 meters. The total area of Antarctic ice sheet is as high as 24.5 million cubic meters. If it melts completely, the ocean surface of the earth will rise by about 60 meters, and the land area of the earth will increase.
Let's make contributions to this human home together! ! !
Now that China's economy is developed, it can be said that it keeps pace with the times. Ever wonder how much pressure the earth will bear? With the increasing population of the world, there are great problems in the environment and resource supply. Not to mention other resources, let's talk about water resources first.
Water, we are familiar with it. In daily life, it is indispensable. People say, "Water is the source of life." As we all know, China's fresh water resources are very scarce. If there is no water, it is equal to human death, or even extinction ..... It can be seen how important water is and how important it is to save water resources. In fact, saving water is very simple, that is, a small action can solve a big problem.
That day, my mother cooked me a delicious meal, and the rice washing water stayed. Grandma saw it and was about to pour out the rice washing water. Mom said, "Mom, you can also water the flowers by washing rice. This will not only save water resources, but also raise flowers. " Grandma listened to her mother's words and left the rice washing water. Then, I saw my mother pour rice washing water into a covered tube. I asked curiously, "Mom, why do you want to pour rice water into the bucket?" Mom said, "So we can accumulate water together." When it's time to water the flowers, you can use them. "
Is to keep this bucket of water, if every family can do it, how much water resources will be saved!
Do you know that?/You know what? According to the latest data from the Ministry of Water Resources of China, there are more than 600 large, medium and small cities in China, and more than 400 cities are short of water, among which 108 city is particularly short of water. Outside the city, the vast rural areas have also begun to face the problem of water shortage. Taking Beijing as an example, it is estimated that by 20xx, the total primary demand for water resources will exceed 4.6 billion cubic meters, while the available supply is only over 3 billion cubic meters. The water shortage is aggravated not only because of Chinese mainland's special geographical and climatic conditions, but also because of economic development, population increase, expansion of development and construction activities and ineffective protection of natural resources. The utilization rate of rivers has exceeded the international ecological warning line of 30% to 40%, and the ecological water has been squeezed in large quantities, which has destroyed the natural ecology of rivers, and the groundwater has been seriously over-exploited in both urban and rural areas; There is also man-made destruction of water resources, such as coal mining in Shanxi, which has seriously damaged the local surface water and groundwater transportation, and Shanxi has become one of the most water-deficient provinces in China.
Saving water is everyone's responsibility. Only when everyone pays attention to saving water can we leave without water, life will be stable and harmonious, and the environment will be beautiful and comfortable.
Earth-the home where we live. How selfless she is, she deserves our gratitude for a lifetime. Therefore, we should try our best to love her. Let's protect the environment and cherish water resources. Start with me, start with me bit by bit. From now on, let's act!
It's been 20xx years now, and I'm already a famous scientist in cosmology, working in Chinese Academy of Sciences.
This afternoon, I got a call from the headquarters in America, asking me to discuss an important matter immediately. I soon flew to America on my manned plane. Although the sky is big, there are many flying machines, and the air is very poor now. Visibility is only 100 meter. I may accidentally hit someone else's aircraft. Fortunately, I am a super pilot and my driving skills are very good. In such a dangerous situation, I can save the day. Soon, it took only five minutes to reach the destination, and many scientists have already arrived there.
Here, a famous American cosmologist stood up and said that the situation on the earth is very bad now. Many raw materials are lost, forests are destroyed, people are still blasting mountains and filling the sea, and resources are exhausted. The burden on the earth is too heavy, so it can be said that it will not last long. We must think about good ways to save the earth. The plan put forward by German scientists is to leave the earth, give up 99% of human beings, take the elite of human beings and take a spaceship to find a place where human beings live in precedent and make a living there. The plan was unanimously rejected by everyone. Everyone thinks that we should not only enjoy happiness with all mankind, but also overcome difficulties. Old scientist department, is there no other way? You look sad when you talk. I stood up and said: cloning a new earth can not only change our living environment quickly, but also master the secret of human existence and accumulate experience for human beings and long-term development. All right. The old scientist cheered with everyone. As soon as he struck the table, he said, why didn't I think of that? After getting everyone's unanimous approval, we will do it. From scheme design to organization and implementation, we go all out.
After several months of design and planning, we collected raw materials from all over the world, mainly high-quality and pollution-free raw materials such as soil, water, plants, animals and various elements, and synthesized them according to different proportions, and put them into the air similar to the greenhouse we set up in advance to give sufficient sunshine and temperature. A few months later, we made a final investigation and demonstration of the No.2 Earth, and determined that the ratio of seven oceans, five continents and small land was still 7: 3. We put it at a proper distance from the earth in the universe, and it has been growing and getting bigger. Finally, in two years, it grew to the size of the earth and stopped growing. The conditions there are comparable to those of the earth, with abundant sunshine, fresh air, birds and flowers, rich specialties and beautiful environment. Many people moved there to live. The production, construction and development there are the same as those on the earth, but people pay special attention to saving energy and protecting the environment. People live in peace and live and produce happily. Our No.2 Earth is the same as the original Earth. After most people immigrated to Earth 2, the harsh environment of the original Earth has also been treated and improved, and the governance of our two Earths is getting better and better. People can come and go like relatives.
We also hope that mankind can remember the lessons of the earth crisis and not make a second mistake, which will destroy our home-the earth. Let us defend her together. She is our living parents. Let's cherish the rare living environment today.
In fact, "low-carbon environmental protection" is not only a slogan, but more importantly, it is implemented in everyone's actions. Everyone has the obligation to abide by it and reach an agreement with Mother Earth.
In summer, hot weather sweeps across the country, especially in urban centers. The temperature is suffocating. It is the river next to our Zhonghai Kangcheng community. What about before? It's muddy here, and there are often dead fish floating. The smell of decay can be smelled thousands of miles away. Passing people cover their noses and quickly leave this uninvited place. Now, the river has become brand-new, and the fish are vivid and full of vitality. The river is as clear as a mirror, which can reflect "the whole" Cannes. Every drop of water is as radiant as crystal dew.
In order to protect the environment, saving electricity is a must! Nowadays, there are many kinds of electrical appliances. In hot summer, every household is equipped with air conditioning. You can save a few dollars by driving less 1 hour. After a long time, you can save money and electricity. This is the best of both worlds! High cost performance!
Finally, garbage collection. Usually, the old light bulbs, packaged products, waste coke bottles and newspapers at home should be classified, and harmful waste, batteries, lamps and cosmetics should be stored separately and sent to special recycling places to avoid environmental pollution.
As long as you bend down to pick up a piece of garbage, he bends down to pick up a piece of garbage, and people all over the world bend down to pick up a piece of garbage, Mother Earth will grin, won't she?
Comments by famous teachers:
Now the earth is riddled with holes, and Mother Earth is overwhelmed. If human beings want to survive, they must take action to protect the earth. As the author said, "low-carbon environmental protection" is not only a slogan, but more importantly, it is implemented in everyone's actions.
This paper gives a wonderful description of the rivers near Kangcheng, and highlights the importance of environmental protection by comparing the past and the present. The author of this paper also puts forward the environmental protection measures of "saving electricity" and "recycling garbage", which makes people understand that environmental protection benefits others and benefits themselves, and highlights the theme of the article.
Some sentences need to be revised: "river" should be changed to "river", "it is necessary to protect environment and save electricity" should be changed to "it is necessary to protect environment and save electricity", "waste coke" should be changed to "waste coke bottle", "as long as you bend down to pick up a garbage, the whole world will bend down to pick up a garbage" should be changed to "as long as you bend down to pick up a garbage, he will bend down".
Keep trying!
The earth crisis composition 7 "Dangdang" is 3052, and I personally set up every home. I forgot to tell you: there are no bad people on the earth now. The world is full of joy.
Rinrin, we have a visitor. "It's Dr Ka Kui Wong. What can I do for you? " The doctor told me the whole story: it turned out that Mars and Mercury were United against other planets in the Milky Way. Every planet in the galaxy (except the earth) was destroyed by them. Before long, Mars and Mercury will send the most advanced spacecraft with the most advanced biochemical weapons to destroy the earth. Now there is a UFO at an altitude of 0/00000 miles from the Earth/KLOC-,which is determined to be a Mercury spacecraft. No, it's only nine Wan Li away from the earth now. How fast!
According to our records, other galaxies have been violently hit by this ship. We have developed a weapon to counter the strong impact. This kind of weapon is called super shock nuclear weapon. It is estimated that the spacecraft will reach the earth in 9 seconds.
Time doesn't allow us to think much. We prepare the prepared weapons, aim at the high altitude, and count down to nine seconds: "nine … eight … seven … three … two … one." I see that our weapons gather energy from all corners of the universe, and when it reaches a certain limit, it is emitted. A dazzling beam of light rushed at the spacecraft only a few centimeters from the ground, and then there was a loud bang. The ship was disintegrated by our weapons in an instant, and it should be reunited in half an hour. We estimate that it will destroy the earth. Dr. Coma predicted that our actions would trigger a galactic war. ...
If you want to know what will happen next, listen to the next chapter.
Earth Crisis Composition 8 In 20xx, the earth became a foul-smelling planet, which was the result of human pollution. People are afraid to go out.
But what about animals? Scientists never thought it would do great harm to animals and plants. At this time, the elephant's eyes are red, its volume becomes larger, and its feet become claws. Monkeys can become phantoms, walk upright and grow hair; Tigers have colorful patterns, wings and manes, and tiger tattoos on their legs. Birds grow two pairs of bone wings, the soles of their feet become bigger, and the feathers are darts; Rabbits' eyes turn blue, they eat everything, their appetite is amazing, and their reproduction speed is fast ... plants become Jurassic plants. Instead of staying in zoos, these mutant animals ran out of zoos all over the world and attacked cities. Weak Japan has been destroyed, so we must use the highest technology. We made "Hero Show" chips for Huluwa in China, The Avengers in the United States, cf in South Korea, Naruto in Japan, and ben 10 in Britain ...................................................................................................................... Fight to the death with mutant species. Huluwa burned all the small mutants and sprayed water to control the fire. People in The Avengers cooperated with each other and killed all the large mutant animals. Ben 10 turns into a beast and leads to all traps, and turns into a fire man to burn all mutated plants, leaving plants that have not mutated. Naruto-Naruto, Spirulina Pills, Avatar and Phantom, killing rabbits and some agile animals. Doraemon in Japan took out the reduction spray and changed the animals and plants back. A big crisis was solved with help. Can be found and sent by the head of the Star Alliance.
The earth is a beautiful planet. I don't want it to suffer such a crisis again. Please protect the earth, ok?
If we destroy the earth like this, it will probably become like this. Without those heroes, mankind would be extinct.
