1. There are no boundaries in life composition

Once upon a time, we lamented the fate of our fate, and we were indignant at the unfairness of life.

Let us fall into the abyss of pain. However, we should understand that there is a kind of fall called forging ahead, a kind of loss called gain, and a kind of failure called success. There are no boundaries in life.

Life has no boundaries. The so-called right and wrong, success and failure are just our artificial divisions. There is a saying: "When you pretend to be true, the truth is also false. There is nothing but nothing."

This is the case in life. If you succeed in your career, people will say you are successful, but if you are really Was it successful? Maybe your family is rich, but your heart is empty, so you have not succeeded; you have accomplished nothing and done nothing, and people say you are a loser, but have you really failed? Maybe you still have a hard-working heart, maybe you live a happy life, so you have not failed. There is no boundary between success and failure. They are flames burning together. The river nourishes us and the flame shines on us, so we don’t have to worry too much. Pay attention to the right and wrong, gains and losses in life. There are no boundaries in life. We don’t need to divide them clearly like day and night. A poet said it well, we must put a light in our hearts.

Where is the light that you step on? "As long as we have an excited heart, what if we step into the "dark night"? I don't appreciate the flowers in my hands, I only love the garden in front of me, I don't expect luck to come, I just hope that my road will extend a little bit . There are no boundaries in life. Everything needs to be tried, created, and sublimated by ourselves. It does not matter whether we succeed or fail, and it does not matter whether we gain or lose.

2. A 500-word essay on science without boundaries and endless exploration

< p> Materials: 1. On February 1, 2003, the U.S. space shuttle Columbia exploded while returning from space, killing seven astronauts. This was another tragedy in the history of human spaceflight, and the world was shocked.

2. In the long process of human exploration of space flight, generations of explorers have sacrificed their precious lives for it. According to legend, at the end of the 14th century, in the Ming Dynasty of China, there was a man named Wan Hu who asked others to tie him up. On the chair, he held a kite in each hand and tied 47 rockets, the largest at the time, to the back of the chair. Then he asked people to light the 47 rockets together, trying to use the thrust of the rockets and the lift of the kite to fly into the sky. It failed. He was the first human being to conduct a manned flight test using a rocket, and he was also the first human being to devote himself to exploring space flight. In the autumn of 1996, the International Astronautical Federation annual meeting was held in Beijing. Two Russian astronauts and three American astronauts took a group photo in front of the Wanhu statue in the China Science and Technology Museum to commemorate this pioneer who first dedicated his life to the dream of human spaceflight.

3. People in the former Soviet Union and the United States sacrificed their precious lives during the manned space flight experiments

4. One view is that human life is the most precious in the world. The risk of human spaceflight is too great. In order to reduce unnecessary sacrifices, manned spaceflight should be stopped and the development of unmanned spacecraft should be focused. Another opinion is that mankind must always devote itself to exploring unknown areas, and exploring space is the responsibility of all mankind. It is a great cause that requires generations of people to fight and sacrifice for it. Humanity has just begun to enter the vast space. Fatal accidents during space flight cannot stop the progress of human exploration of space. Manned space flight should continue to advance... Sample essay: Exploring the Behind the Success

I remember one of Bing Xin’s early poems: The flower of success, people are only amazed at its current beauty, but they don’t know that her buds were soaked in the tears of struggle and sprinkled all over the sacrifice. The blood rain. Remember the ad slogan of Qibu Gao: There is justice in the world, and there will always be rewards for hard work. This poem expresses the true meaning of exploration and expresses the voice of the explorers throughout the ages. The entrepreneurial footprints of wise people all confirm a simple truth: where there is hard work, there is victory, and where there is exploration, there is success.

The landing of an apple is a common thing, but it caused Newton to think deeply. Selfless inference, he finally discovered the "law of universal gravitation" that shocked the world. Birth, aging, illness and death are all normal phenomena in life, but Sakyamuni wanted to find out the root of it and find an answer. For this reason, he remained unknown, practiced meditation quietly, and finally founded Buddhism.

Xu Xiake walked across the green mountains to create a great road; Su Shi visited Shizhongshan at night; "every word in "A Dream of Red Mansions" seems to be blood"... there are countless examples like this. Human beings have gone from eating hair and drinking blood to learning how to use fire, from living in caves on grass to living in high-rise buildings, from carrying two oxen to scientific farming, from seventy-two apprentices to thousands of students filling the school, from carriages to cars, ships, airplanes...this Exploration again and again allows us to bid farewell to ignorance and backwardness and enter a new era.

In the process of exploration, we send artificial satellites into space one after another for scientific research and travel; chatting online, the end of the world is still close at hand; going to the bottom of the sea for sightseeing, dreams become reality; robots have become our slaves , His Majesty bowed his head and bowed his head. In our exploration, we have deciphered the composition and arrangement of DNA and interpreted various genetic codes; we have overcome the stubborn disease that plagues mankind - Alzheimer's disease; the birth of cloned sheep and pigs has declared that rejuvenation of human beings is no longer a fantasy. During our exploration, we discovered the fossils of great apes about 45 million years ago, found a lost port city in Egypt, and learned about the mystery of a sunken ship that had been buried for 136 years. Scientific research on the Tarim River discovered the ruins of the Xiaohe Cemetery, interpreting the mystery of the "Big Ears" of the 1980s and the confusion of the "Wandering Lake" for a hundred years... There is no end to exploration, and exploration will make human society better Civilized and prosperous.

Of course, flowers and thorns coexist, and failure and success are companions. The journey of exploration is not easy. Balzac said: "Failure is the teacher of life." Napoleon said: "The glory of life lies not in never failing, but in rising again and again." For those with ambitions, failure is just a fortune. In the process of exploration, Kong Sage traveled around the world and encountered obstacles. Qu Yuan was slandered and exiled by King Huai of Chu. Zuo Qiuming became blind... Writer Yan Wenjing failed the college entrance examination six times and was not discouraged. Hua Luogeng dropped out of school because he could not afford the tuition and did not lose his ambition. The United States "challenged The "Zero" space shuttle exploded after takeoff, and the U.S. "Columbia" space shuttle exploded when it returned from space to the atmosphere. This has not stopped mankind's exploration of the universe... Difficulties and failures in exploration will only make our footsteps more solid. More calm.

Exploration never stops, nor does human progress. I remember a great man once said: "A person should have three minds in his life. One is the innate brain, the other is the mind obtained from books, and the other is the brain obtained through continuous progress and exploration in social practice. Mind. "We have reason to believe that in exploration, people will create a better future. Diligent in exploration, mankind will achieve ultimate success in everything!

Explore, young man! Let the footsteps of progress be transformed into a symphony of creation, and let the hard work and sweat depict the beauty of the times. Competition and prosperity call for new leaps, and opportunities and challenges inspire new pursuits. Let us insert the plow into the vast soil of the Republic of China and build a civilized, auspicious, prosperous and powerful New China! 3. Write

There were many interesting things when I was a child, just like the stars in the sky, there are countless interesting things. One of them is the most unforgettable thing about eating fruit ice milk tea.

When I was 6 years old, the sun was shining brightly and spring flowers were blooming. My friends and I went shopping. As we were walking, we saw cherries being squeezed in a juice shop. I thought, aren’t those cherries? There are so many in my backyard! So, my friends and I said, "Let's make fruit iced milk tea! If you want to eat, come home with me!" We arrived home quickly, and my friends rushed to pick the fruits from the backyard. I was responsible for Wash the fruit, cut it, put the fruit into a juicer and squeeze it, then pour the juice into a cup, put it in the refrigerator for 1 hour, take it out, add shredded bread, shredded strawberries, and shredded chocolate. , add milk.

This is how fruit iced milk tea was born. In the backyard, my friends and I happily tasted it, ah! So delicious.

4. Essay on the topic "Happiness has no limit, danger has no edge"

Life is like a cardboard box. If you dare to poke it open to reveal the secrets inside, that is an attempt. During the last summer vacation, I I once made a dangerous attempt and almost ended it.

That day, we were playing downstairs. Suddenly, I saw the sliding security door installed in a garage being opened. I suddenly I wonder if it would be fun to climb up to the roof and retrieve the baseball that was thrown up! I put forward my opinion, and everyone immediately agreed. I am more agile, so I was the first to run over and crawl. I rolled up my sleeves, firmly grasped the mesh door with both hands, and pushed hard with my feet. Like a monkey, I climbed up quite neatly. I saw that my hands had reached the roof, but my hands kept slipping, my body fell straight down, and my feet kicked wildly. I was so anxious that I felt cold and broke out in a cold sweat. Fortunately, I took advantage of the situation. I grabbed the horizontal bar on the door frame and didn't fall off. Ha! After a false alarm, I calmed down and grabbed the eaves with both hands again. With a strong force on my feet, my body seemed to fly up, and I finally climbed up to the roof steadily. My friends were stunned and did not dare to imitate me. The "trapeze" action started, and they circled up from other places and climbed to the roof. I saw the baseball that I threw up when I was playing a few days ago, and I wanted to get it. But there was only one way to get there. There was a narrow wall one brick wide connecting it. I opened my arms and walked forward cautiously like a tightrope walker in acrobatics. When I was about a third of the way there, my foot slipped and my center of gravity sank to the left. I hit the wall. I staggered, broke into a cold sweat again, and felt top-heavy. I had no choice but to lean on the wall and slowly crawl over. I finally got the baseball. Although I completed my "heroic" feat, "it's easier to go up the mountain than down the mountain." "It's difficult." Standing at a height of one and a half meters, it would be very difficult to go down the way I came. So, I squatted on the eaves, held my hands, took a deep breath, and jumped down! With a "boom", I felt a strong shock in my body. My ankles were numb. I sat on the ground and couldn't get up for a while...

This was really a dangerous attempt. I suffered a lot from it and my ankles hurt. Several days! I also understood from this: A person must be brave but not blindly take risks or make unworthy sacrifices. 5. Urgent needs

1. My future I like science very much. When I grow up, I must be a scientist. Take a rocket to space to observe and invent things that are useful to everyone.

I like to read science books when I have nothing to do. Science books are very interesting. That day, after I finished my homework, I took out the science books from my school bag. I saw the joints of our ears, the joints from the head to the neck, and even the joints of the whole body. I watched it many times and I never found it boring.

But sometimes I think that I must be a scientist, but sometimes I slowly feel that I cannot be a scientist. One day I went to play with the little sister in the canteen downstairs, and I asked this question: "What do you want to be when you grow up?" She said, "What about you?" I raised my head and said, "I want to be a Scientist."

She said: "I want to work!" I said: "What a great dream." Once again, I met my classmates when I was going up the stairs at school.

I still asked the question: "What is your ideal?" She replied: "I want to be a doctor." I often ask people this, and they either answer the police or the teacher... The more I listened, the more I felt that I could not be a scientist. When I was in the first grade, my grades were very good, so I was full of confidence in the scientist side. By the second grade, I was confident, but by the third grade, I gradually lost confidence.

When I was in the third grade, I didn’t get 100 points in the exam without being praised by the teacher like before. What the teacher said in class went in one ear and out the other. The teacher said that all the students in our class would think fast. I often make typos in Chinese; I tend to be careless in math; I don’t make any mistakes in English, they rarely happen.

I want to be a scientist. If I don’t have knowledge, I won’t even think about it. So I’m in fourth grade and school has only started for one week, so it’s not too late for me to study hard. I wrote on my blackboard "Study hard and make progress every day."

I read it every day. I must study hard and make progress every day. Only then can you realize your dreams.

2. Time slipped away from me in a hurry, everything seemed to pass so fast.

In the blink of an eye, I am almost in sixth grade. Now, I wish that time could stay at this moment and stay in the beautiful memories.

I am now 11 years old, and I am no longer the kid who was babbling, and I am no longer the Ran Jinying who always thinks of my parents. I, now a little adult, want to learn more related compositions >> Time slips away from me in a hurry, everything seems to pass so fast.

In the blink of an eye, I am almost in sixth grade. Now, I wish that time could stay at this moment and stay in the beautiful memories. I am now 11 years old, and I am no longer the kid who was babbling, and I am no longer the Ran Jinying who always thinks of my parents.

I, now a little adult, have to learn to live independently and know how to get along with others. Sixth grade means that primary school career is coming to an end.

It means that I have to give something back to my parents and teachers. Sixth grade means that there is a test for my six years of study. The result depends on my own efforts.

Mom, I want to say sorry to you. You have done so much for me in the past few years. Your love is like a bright light that illuminates the dark world in my heart. Your love can accumulate into a mountain.

I think a thank you is never enough. You often tell me that studying hard is the most important thing.

The teacher said that his parents always told him to study hard, but some classmates simply couldn't listen. But I don't, because that sentence is all my mother's expectations, isn't it? Some students always nag their parents and don't care at all when their parents tell you to put on extra clothes. Only when you have a fever do you know you should listen to them.

Teacher, I want to say sorry to you, because we are too ignorant and made you angry. Although you always say that students' grades are nothing to you, I know that of course you hope that the students you teach will all be outstanding.

Perhaps we have not yet realized your good intentions. When we grow up, we will realize that we were wrong. If you don’t study hard now, what will happen to your future life? We live in a competitive world and we must remember that our time to study is limited.

Time is limited, not only because life is short, but also because people are complicated. We should strive to use all our time to do the most beneficial things.

Dad, I want to say sorry to you. Sometimes I go home at night and make you worry. Dad, you always advise me to study hard. On the surface, you always don't care about me. , but everyone knows the hearts of parents in the world. You work hard alone and it's tiring, I know.

You should also pay more attention to your body and don't be too tired. Dad, believe me, I won't let you down.

Students, I want to say sorry to you. Sometimes I always don’t care what you think. In fact, every time I make a classmate angry, I feel very uncomfortable. I shouldn't do this.

Maybe some classmates who don’t understand me will hate me. In fact, I don’t care about other people’s opinions. Because, I always remember one sentence: Go your own way and let others tell you! If you always care about other people's opinions, you will definitely feel inferior. Why do you feel inferior? You don't live for others, you live for yourself.

Why should you care about other people’s opinions? In my dream, I know you are in front of me. My desire, longing and yearning for you lead me step by step towards you. Maybe the road will be a little twisty and bumpy, but this cannot stop my sincere heart from looking for you. , I will rush towards you with all my strength, who makes you my dream? There is still a long way to go. Even if there are difficulties ahead, we must overcome them.

Work hard and study hard for your future. 3. Suddenly I feel that I have grown up and am no longer a child that everyone protects. Wandering alone on the street, feeling confused and lonely in my heart! I don't know what my future holds.

Like a calm lake, now there is no ripple. But I vaguely felt that there were waves inside it.

What makes me have such a premonition? A few tears dropped from the sky, making my eyes blurry and soaking my heart. I can't wipe it away without leaving a trace.

It’s me who has become sentimental. The joy and laughter of the sunset are gone.

It seems that every laugh I make is so hypocritical and forced.

My own tears have not come for a long time.

I don’t know when, where or why I shed tears last time. But why do I shed tears in the dark night without knowing anything.

The tears were so heavy. 6. Composition: Music has no boundaries

Music is the most beautiful sound of human beings. Without it, life will become dull; it is precisely because of the existence of music that we feel the richness of life.

Since the babies have just arrived, music has entered their ears. With the soft and beautiful lullabies, the babies fall into sweet dreams. At this time, the soft music was floating everywhere in the streets and alleys.

Music can also cultivate sentiment. Music, whether it is lyrical or passionate, we can all get inspiration from. From "Start Over", I learned how to face setbacks and failures; from "Symphony of Life", I appreciated the majesty of life. It is this music, always by our side, that makes our souls gradually mature.

Music should not only be listened to, but also the tone of its composition and the emotions expressed. Music can purify the soul and gradually mature. If we listen to music with new ideas, we will not only enjoy how beautiful and good the piece of music is, it will also make our lives more colorful.

Music - everywhere. From childhood to adulthood, from morning to night, you can enjoy wonderful music in the streets and alleys, and at home. It makes our lives full of happiness and joy!

I like to wear headphones and listen to music on the way out. There’s nothing picky about the music or the singer, as long as it sounds good. Often I am very familiar with a certain melody, but I don’t know who sang it, what its name is, and what its content is.

Sometimes there is a very strange feeling. When you are in a moving car, looking at the busy world outside the window, and a sad tune is echoing in your ears, you will There is a sense of being in a certain stream of consciousness or a literary movie, which will produce an illusion of this shore and the other shore. Everything is illusory and everything is a story. It seems that you have jumped out and examined the person who is walking in your own story. Own. At this time, people tend to become more sensitive to the passage of time and the experience of mood, and seem to be much more fragile.

Most of what I like is music with a touch of folk style. When the singer sang softly in his ears, some sadness in his heart was drawn out bit by bit until it overflowed. So I never wear headphones all the time, and occasionally take them off to allow myself to return to reality, so as not to be overwhelmed by my own sadness.

I am not a sentimental person, I am just too sensitive. A teacher I admire once said to me: "Being too sensitive will cause you too much pain." I think that's the case for me. In fact, life is still so plain and uneventful. I am also experiencing and enjoying this kind of plainness. But deep down, I may be the kind of woman who says "the green mountains are looming, but the hatred is lingering". I always hope that my life will be richer and more legendary. Zhang Ailing said: "I don't like music very much, because music always has a bit of sadness." I think that's because she is too strong and too calm in her words. But I think words are too easy to disguise and be exploited, but songs are hard to deceive. I'm still willing to listen.

From the singing along the way, what I heard and experienced was a real, almost tangible loneliness, not reality, but a state of mind 7. A 100-word essay on the boundless thoughts of childhood
