In study, work and even life, everyone is familiar with composition, which can be divided into primary school composition, middle school composition and college composition (thesis). Have no clue when writing a composition? The following are six compositions carefully arranged by me in the first lesson of grade three for reference only. Welcome to reading.
On the first day of school, I stepped into the gate of experimental school, with tall teaching building, straight flagpole and green playground. All this is so quiet and harmonious against the blue sky. [Type the summary of the document here. A summary is usually a brief summary of the contents of a document. Type the document summary here.

The first class at school is not Chinese, math or English. It is a test of perseverance and unity, a test paper of persistence and courage. It is military training. Loud whistle sounded, and rows of neat and straight teams suddenly appeared on the empty playground. In an instant, the silence of a summer vacation on the playground disappeared at that moment. Instead, it is a rainbow of slogans and neat steps. They are the most beautiful sounds. The military posture has become the most obvious action on the green playground this week. Looking around, there are faint olive green on the playground, and more serious faces. Lang Lang's reading voice turned into a serious and neat military song there. I like the campus at the moment, like her strength, like her strength, like his seriousness, like his persistence.
I bravely persisted in the first lesson, and the pain of the first lesson could not be expressed in words. Perhaps it is even more painful for those of us who only study hard with books in our arms every day. There are a few white clouds floating in the air, but the scorching sun is still hanging in the air. In the face of sniper-like sweat, you can only endure, endure and endure again. In this first class, I learned to be persistent, persistent, earnest and strong. He made me grow up a lot, learned a lot, and made me good friends with everyone. The first lesson is the first lesson for me to understand the campus and the first lesson for me to make friends. He was the first class, a class that benefited me a lot, and a class that I will never forget. He is in military training-a memory that can never be erased.
Last night, I watched the first lesson at school, and beauty was beside you. There are many kinds of beauty in it, but what impressed me the most is the last lesson-harmonious beauty. Beauty of Harmony tells the story of the gymnastics men's team winning the gold medal together. Uncle Chen, they rehearsed badly, almost the worst in the whole history. But instead of blaming each other, they encouraged each other. On the day of the game, they encouraged each other again before the game. When everyone has finished the action, others will come and give him a high-five hug. Finally, they actually won the gold medal through hard work.
Uncle Chen's last sentence shocked me: no one is perfect, only a perfect team. This reminds me of our team. One afternoon, we were doing a blackboard newspaper. I stand on the chair and write. Jiang protects me. Teng Lin Kai helped me pass the chalk and rag. Cenwangyi cleaned up, and I almost fell down several times. Fortunately, Jiang protected me. Through our efforts, the blackboard newspaper was completed. It's really beautiful. Let's clap our hands together From this, I understand that everyone is essential in a team. Everyone has his own strengths.
The first lesson of the first semester is the third grade composition. The winter vacation is over and the new semester is coming.
At the beginning of the new semester, Shijiazhuang Radio and Television Life Channel, together with the Municipal Education Bureau and the Municipal Environmental Protection Bureau, once again presented the course of urban environmental protection and ecology-the first lesson of school.
The host asked who set off the firecrackers first, and many students asked, but we didn't know there were many pollutants in the firecrackers. When setting off firecrackers, many harmful gases, such as sulfur dioxide and nitrogen dioxide, will be released. When sulfur dioxide enters the atmosphere, it is oxidized into sulfuric acid (SO4), which forms acid rain in the clouds, which can strongly corrode buildings and industrial equipment. Acid rain will lead to the death of trees and forests, the extinction of fish and shrimp in lakes, the destruction of soil nutrition, and the reduction or death of crops. Nitrogen dioxide can irritate eyes, nose, throat and lungs; In addition, it also forms urban smog, which affects visibility; It will form small droplets of nitric acid and acid rain. Of course, in the process of setting off firecrackers, not only these two kinds of harmful gases are produced, but also unburned gunpowder and residual dust, all of which are a kind of pollution. It can be seen that the harmful substances released by firecrackers pollute the air.
Burning coal will also produce pollutants, mainly sulfur dioxide, nitrogen dioxide, carbon dioxide, carbon monoxide and so on. Automobile exhaust contains carbon monoxide, nitrogen dioxide and so on.
There is also a lot of pollution in industry, such as particulate matter, which refers to liquid and solid substances in the atmosphere, also known as dust. Sulfur oxides, including sulfur dioxide, sulfur trioxide, sulfur trioxide, sulfur monoxide, etc. The oxides of carbon mainly include carbon dioxide and carbon monoxide. Nitrogen oxides include nitrous oxide, nitric oxide, nitrogen dioxide, nitrogen trioxide, etc. Hydrocarbons such as methane, ethane and other hydrocarbon gases.
It is everyone's responsibility to establish environmental awareness from me, pay attention to and care for the ecological environment of our city.
On the evening of September 1, my mother and I watched >.
& gt is wonderful, teaching us a lot of knowledge that we can't learn in class. The whole program revolves around the phrase "knowledge protects life". A * * is divided into three main points: potential, persistence and group. And every point is very detailed, even illustrated by facts. What impressed me the most was a true story in The Potential: On May 12 this year, an earthquake of magnitude 8 suddenly occurred in Wenchuan, Sichuan. In Sangliangzao Middle School in Anxian County, which is five kilometers away from the epicenter, more than 2,300 teachers and students evacuated safely in just 1 min 36 seconds, with no casualties. What made the students in Sangzao Middle School create such an amazing miracle? It is potential.
In fact, everyone has immeasurable potential, which we need to tap all our lives.
Therefore, in the future life and study, we must not shrink back. No matter what difficulties we encounter, we must believe that we have the ability to overcome many difficulties.
Let us always remember eight words: never give up and surpass ourselves!
Today we start school. Because of G20, we started school in Hangzhou a week later, but the scene of "the first class" still caught my eye.
In the first class of the semester, we listened to the revolutionary story told by the old Red Army. I learned that during the 25,000-mile long March, the Red Army had to climb snow-capped mountains, cross grasslands and fly over Luding Bridge. They had no food, no clothes and no medicine, but they did not fear difficulties and went forward bravely, and finally won the revolution.
A Red Army officer said that her father had no anesthetic during the operation, so he had to tie the patient to the door panel, put a towel in his mouth and press his arm with a farm saw. I feel so painful after listening to it! But her father insisted.
Another grandmother said that the Red Army wore sandals without shoes, and everyone only ate a soybean every day, and there was no food. Some young soldiers were poisoned by eating some wild vegetables. I can hardly believe it when I hear this. How can a bean be full? Think about how happy our life is now!
I can't help cheering for them when watching the race to fly over Luding Bridge. One of the chubby brothers was so anxious that he stepped on the mat laid by others and fell under the bridge. It seems that this game needs everyone to play slowly and steadily, and it can't be urgent.
After reading the first lesson in school, as a primary school student, I should learn the indomitable spirit of the Red Army and not give up easily in the face of difficulties.
The first lesson of the first semester I watched the first lesson of the first semester on September 1. The first lesson of the first semester is mainly about "dreams". Dreams are the driving force for progress, because only dreams can persist and only dreams can shine. In fact, dreams are not out of reach. They are like the stars in the universe. As long as you work hard, you will definitely be able to touch them. Opportunities are reserved for those who are prepared. You can do anything as long as you work hard.
After watching this program, I understand that dreams are the driving force for progress and dreams can be realized through hard work. My dream is to be a scientist, so I will study hard and listen to the teacher carefully to realize my dream.
