One afternoon in 2002, I was swimming in the sea of questions when I suddenly saw a difficult problem, which occupied a whole page. Thought for a long time, at a loss, put his forehead on the desk and fell asleep. ...
Suddenly, there was a sound of reading in my ear. I opened my sleepy eyes and saw that the classroom was quiet and empty. Running outside, I saw the huge campus, crowded with students, bathing in the morning sunshine and enjoying morning reading on the lawn, Woods and flowers. This kind of atmosphere makes people feel enthusiastic about learning, so I also walked out of the classroom and walked into this wonderful environment with a Chinese book in my hand.
The bell rang and the students came into the classroom one after another. The amiable Chinese teacher first stepped into the threshold and pulled out a survey about modern people's life from the internet to cut the population. The teacher had a rich and intense discussion with everyone. Opinions are expressed and a hundred schools of thought contend. Finally, the teacher made a brief summary. The assignment is a short paper, which is due in a week. Next is English class. Ten minutes of grammar knowledge, the rest is a relaxed real person simulation. Everyone on stage and off stage is an English paradise. The headache math exam is no longer scary, and there is no teacher invigilating in the classroom. The oppression of scores began to disappear, and students were no longer slaves to scores and cheating, but really wanted to understand and master knowledge.
Only one master and one deputy are arranged for the afternoon class. After two classes, I followed my classmates to the outdoor and playground. You can see boys and girls alive and kicking on the runway, in the green and under the basketball stand. After an hour of returning to nature and enjoying oxygen, the major laboratories and research groups of the school are fully open. In the reading room of the library, everyone is quietly learning knowledge; The English corner is also very lively; Surfers in the computer room are more "cool"; Biological laboratory, a small scientific research project, has gathered many enthusiasts. ...
There is more than an hour of evening self-study after dinner, which is more than enough to deal with homework. The following time is arranged by myself. The screening room is showing scientific and educational films and famous films; Wonderful inter-school debate. Today's topic is "Cloning human morality?" ; In the gymnasium, the basketball match between classes is in full swing. All these things, if you don't like them, you can count the stars in the moonlight. ...
Thinking about people, I actually drooled all my exercise books. At this time, I was also taken back to reality by the teacher. I looked up and looked around, my head was sparse, but it was too late to write and complain.
In the dream campus, people are looking for it in thousands of Baidu, and the garden is in the Year of the Monkey. Alas!
It's also my blue sky
Ancient poets wrote about the sky, "there is no dust in the sky"; The sky written by modern writers is "the blue sky is spotless and crystal clear".
Unfortunately, it is rare to see such a beautiful "day" now. Especially in cities or industrial areas, it is really uncomfortable to be shrouded in smog all day. In the face of all this, you may be tempted to sigh: "Fresh, refreshing and clear breath, where have you been?" Hurry up and cure the "disease" of the atmosphere, and give me a blue sky and a red sun!
We really have a lot of things to do, and the most important thing is to try to reduce the discharge of pollutants.
Smoke and dust are mainly produced by the endless combustion of coal and oil. By improving the combustion mode, the fuel can be fully burned, and the smoke can be greatly reduced.
Try not to burn loose coal, develop coal gasification and liquefaction, and reuse the fuel containing a lot of ash and sulfur after washing. The pollutants produced should be recycled by absorption, catalysis, adsorption and condensation, so as to turn harm into benefit and reuse.
Even pollutants entering the atmosphere, we should try our best to reduce their harm. We should strengthen the greening of the city, plant more flowers and trees, and open up more parks and avenues.
From the point of view of preventing global warming, to control the growth of greenhouse gases, especially carbon dioxide, we should try our best to use natural gas as fuel. If we can cancel the small chimneys of one household, provide central heating or implement power supply and heating cogeneration, we can save fuel and reduce carbon dioxide emissions.
If the secondary utilization of aluminum in the world is doubled on the existing basis, the pollutants discharged into the atmosphere can be reduced by 6,543,800 tons per year.
There are more than 400 million cars in the world, which emit about 654.38+83 million tons of carbon dioxide every year. In order to reduce the greenhouse gas emissions of automobiles, besides limiting the number of automobiles, saving fuel consumption and installing purification devices, cleaner fuels such as methanol and ethanol should also be tried to develop public transport vehicles and electric vehicles.
Finally, the development and utilization of clean new energy is the most fundamental way to reduce air pollution. Such as nuclear energy, solar energy, wind energy, biomass energy, geothermal energy and other energy sources are clean, rich in reserves and have great development prospects.
The destruction of the ozone layer is a global problem. The United Nations Environment Assembly decided that the production of chlorofluorocarbons, the "culprit" that destroys the ozone layer, will be phased out at the end of 1995. However, the life span of HCFCs is 50- 100 years, and150,000 tons of HCFCs have been lost to the atmosphere. So far, only a small part has destroyed the ozone layer, and most of the rest are still in action. The ozone layer will continue to be destroyed and will reach its peak in the first 10 year of the next century. As for the complete return to normal natural level, it will take at least a century!
Air pollution is caused by human activities, and finally it has to be solved by human beings themselves. It's just time waits for no one. We'd better take resolute action from now on and take measures to purify the air and give me back my blue sky!
home
Home is a warm word for all of us. Since the word "home" came into being, there has been a corresponding wandering, but the end point of wandering is to find the paradise of one's soul-home.
In the process of exile, Qu Yuan, who suffered from Li Sao, thought most about that home-Du Ying. So no matter how much he suffers, he can wear a high crown and hold a sword and sing his own "Nine Songs". Once Ying Du was captured and his country was destroyed, he knew there was no home in the world. He went to another place farther away, and that was his home.
No wonder some people say that "when we meet by chance, we are all foreigners". Think about how many people have experienced such a moment: "Where is home in the Qinling Mountains, the snow is holding the green horse back." No matter how elegant Li Bai is, he will "sink back again, and I suddenly think of home"; Du Fu is selfless, knowing that "a letter from home is worth a thousand pounds of gold"; Xin Qiji just wants to return to a happy home with honor. Li Houzhu has the melancholy of "just a river flowing eastward", and it is only a memory of a peaceful seat in the homeland of the Southern Tang Dynasty ... The literati in the feudal era often drifted in the mountains and under the ancient sunset road because of the future, perhaps because of the war, perhaps for other reasons, but when they saw the lights in the city and the sporadic fishing light on the river, or saw the wisps of light smoke on the ridge of Shan Ye, how could they not remember that beauty? But I looked home, the twilight was getting thicker, and the river waves were filled with sad mist!
Even in peaceful and quiet times, the attachment to home is still so strong. My family is beautiful, happy, peaceful, healthy, and brothers and sisters live in harmony. "Beijingers in new york" tells the overseas China people's view of home, that is, in the quadrangle, the family is happily reunited. Huang Lei's home in "Time flies" is the unique charm of Jiangnan water town, and it is also the taste of Grandpa Qi studying there.
At this age, our views on home are even different: we want to own a house of our own, decorate it ourselves and live by ourselves; Who walks with me in the distance in the clouds, stays near the sun, can hide their ears, stay away from the secular noise, and want a clean and free life. Rebellious children think so, but good children don't. They want to live with their parents and put their old home and future home together.
Home is not just a house, it is a haven for drifters and a post for the soul. In short, this is also a way of life that truly belongs to me, my relatives and my family.
One of the happiest things when I was growing up
Childhood memories are beautiful, and together with that little scar, it should become a unique landscape of life.
In spring, I love to eat Sophora japonica on trees. You can eat it raw or steamed. Very fragrant and sweet. There are also elm trees and elm money, which can be steamed and eaten. Every spring, my brother and I will pick a lot of Sophora japonica flowers and take them home for our mother to steam. At that time, I thought those were delicious on earth! Brother likes to dig out the bird's nest, and the tree climbs up at once. We brought the bird back to our home and soon died. It's so sad. I like to grow all kinds of flowers on my house. I like growing flowers. I am so happy to watch them from seed to germination to beautiful flowers! I like flowers since I was a child. I will have my own home in the future. I will plant all kinds of flowers on the balcony, water them every day and watch them sprout and bloom in ................................................................................................................................ Finally, the nails were wrapped in black and red, and the skin of the fingers was red, but they were still wrapped so happily. ...
Childhood! That lifetime of childhood, that childish and ignorant childhood fun, will always be engraved in my memory.
