In primary school, I get along well with my classmates. I don't like being angry. I am very happy all day. Anger will kill brain cells, so when I have conflicts with my classmates, I can basically tolerate them. When my classmates ask me to do something, I always try my best, but sometimes I am shy, that's when others praise me. Sometimes I am reckless. My mother calls me "little daredevil".
Carelessness is a big problem for me, so I often make mistakes in my homework. But I don't believe I can't change it. You see, I will definitely change from "big carelessness" to "small carefulness" in the new semester.
Reading is my greatest hobby. Those novels, magazines and scientific works, I can't put them down when I pick them up-I'm fascinated! I am often moved by the plot and characters in the book, sobbing and giggling for a while, completely immersed in it.
Although I am thin, I like sports! I like playing table tennis very much, and I am still an expert in my class. I like music and art, too. My mother says I have a wide range of interests.
All right, that's all. Welcome to make friends with me.
2. Erasable pen self-report composition 400 words Hello everyone, do you know who I am? Haha, I am a rookie of the most popular pen family in our school-the famous erasable pen.
I have a streamlined back, a height of 1.8 decimeter and an official hat on my head. I am honest, not gaudy, only wearing a blue team uniform with 05 and identification code printed on it. My official hat is made of exquisite plastic, and it says Bai Le. Then, I have to say, my secret weapon-the eraser at the tail, as long as there is a stain on the paper, it will be wiped off quickly in lightning speed. Wipe off the official hat, the pen is ready like a missile, and the refill is full of saliva. I like paper best. As soon as I saw the paper, I couldn't wait to drool and flow smoothly. There are circles of scars and lumps on my shell. What is this for? To prevent my head from separating from my body. I have deep feelings for my young master. He cleans up for me whenever he has time, and never needs me to fight. Once, superfine product accidentally threw me to the ground. He quickly said, "I'm sorry, are you, are you okay?" "Whenever I see that the owners of other partners don't cherish it, I feel very lucky; It's good to have such a master! "I am an important writing tool for people. Although I have many advantages, I also have shortcomings. For example, the handwriting I left on the paper is not long enough for writing documents. Some regrets!
I hope that small business owners will study hard and help me improve when I grow up, which will be more perfect. I believe you will like me better then!
3. The riddle of erasable pen composition Friday, school is over.
I went downstairs with my schoolbag on my back. As soon as I got downstairs, I saw the long-awaited "Mathematics Festival" column on display. I ran to the column of "Mathematics Manuscripts for Grade Four" in three steps, and saw the works of many students in our class on display. I am one of them. I'm so happy! Take a closer look. Why is the handwritten newspaper I wrote with Cheng Jiwen a copy, not the original? I was puzzled, and then I enjoyed the works of other grades with great interest. My "math diary" was also exhibited in the fifth-grade column. I'm so happy! These two days of hard work have not been in vain.
On the way home, I feel that the sky is so blue, the grass is so green, the trees are so green, and everything is so beautiful. Two days after returning home, I have been thinking about a question: Why is my handwritten newspaper plagiarized while other students' are original? The replica is not as beautiful as the original, not only the color is not so bright, but also the bottom plate of the replica is blue.
When I finally went to school on Monday, I asked the math teacher eagerly. Teacher Huang told me: Because my handwritten newspaper was written with an erasable pen, she didn't know that it had been pasted and all the words on it were gone. Fortunately, the art teacher left me a photo, so I had a chance to exhibit it with Cheng Jiwen. When I learned this reason, I regretted writing handwritten newspaper with erasable pen.
After school in the afternoon, I went to Miss Huang's office. Teacher Huang gave me the handwritten newspaper with pictures and no words as a souvenir.
When I got this special "handwritten newspaper", I thought hard. Because the words written by the erasable pen disappear, the gelatinizing temperature will rise. So, if you put it in the freezer and let it cool down, will those words appear? Thinking of this, I picked up this handwritten newspaper with pictures and no words and put it in the freezer of the refrigerator. The next day, as soon as I got up, I went to read the handwritten newspaper in the refrigerator. I was overjoyed at the result! I discovered the mystery of erasable pen: the words written by erasable pen will disappear when heated, but will appear when cold.
When I got to school, I showed the handwritten newspaper to the teacher, which was praised by the teacher and applauded by my classmates. Great! This incident made me understand that you should think more and do more when you do anything, and there will be more surprises as a result.
4. Composition: Good or bad erasable pen is a 200-character erasable pen, which is made of special polymer material as ink base and assembled by special technology. In the process of writing ink, an erasable pigment film is formed on the paper through the pen tip, so that the ink can be erased. Handwriting can be erased in a few hours with an ordinary eraser like a pencil, and the retained handwriting will not be soaked in water and will not fade after a long time. After 48 hours, it will become indelible and permanent handwriting, which can be maintained for a long time. This product is similar to other ballpoint pens in appearance and writing, and has many colors such as blue, black and red.
Erasable pen is a good choice for homework, but when signing important documents or exams, it is best to choose a signature pen. This is because the writing of erasable pen will disappear at high temperature. As shown on the right, the writing of the erasable pen gradually disappears under the baking of the lighter. Therefore, to be on the safe side, please don't use erasable pens for valuable securities and important documents that need to be signed.
Play by yourself.
5. Write a description and introduce yourself with an erasable pen. The 300-word composition is Chang Ru. He is eight years old and is already a third-grade student.
In order to introduce myself clearly and write my first composition this semester, I specially looked at myself in the mirror and observed myself again. I'll find a steel tape measure at home first and ask my mother to measure it for me. The height is1.38m..
Standing in front of the mirror is graceful! Look at my face again. Ah! It's pretty! Look, the round face is white and clean, like the fifteenth moon.
Eyes round and bright, like two black grapes. A small nose grows in the middle of the face.
Red lips, when laughing, two corners of the mouth are upturned, like a boat, really beautiful! Look at the short black hair separated in the middle, and use two small yellow clips to hold it. It looks so energetic! I also have my own hobbies, like painting, making and imagining. One afternoon, when I came home from school, I played on the balcony.
I cut two holes in two large foam boards of the packaging washing machine and put them on my arm. I want to be a robot, but when my arm is raised, two foam boards lean backwards, and I move my arm back and forth twice, feeling as if I want to fly.
I thought: how like a pigeon! I was so happy that I kept flapping my two "big wings" and shouted, "Mom, come and see the pigeons!" Mom ran to look around and asked strangely, "Where are the pigeons?" I said, "Mom, do you think I look like a pigeon?" Mom smiled and said, "How can you be so interesting!" Do people think I'm funny? I like being an interesting child.
In the third grade. If you want to know me, please look down.
I have big eyes, a tall nose and a mouth. Adults say it's cherry mouth. I don't care about his size or my eyes, because I like reading best. My eyes are beautiful. They are the windows to my soul. I didn't try to protect him. For example, when reading a book, pay attention to the distance between your eyes and the book and rest in time.
And my hair, dark, like a dark cloud. Mom said: Our hair is really the same. You have black hair, I have black hair, and your father is still the same.
What a family. My hair is almost as black as my eyes.
Mom and Dad both said: Your hair is really good. My hair is not only black but also hard, as straightforward as my personality.
I'm easy to recognize, as long as I see big eyes and black hair. Remember, don't misunderstand me. I am a friend.
I remember that in the first grade, Wei dropped an eraser and I helped him pick it up. From then on, he regarded me as a friend. Do I like making friends? .
I dream of becoming a PE teacher.
If I were a PE teacher, I would seriously educate them about PE. I will give some fruit candy to some students with good sports achievements, and I will let them train every day if they have poor sports achievements, and I will also assign a lot of homework.
If I were a PE teacher, I would arrange a sports meeting once a week, so that those students with good sports achievements could show their talents. We will have a game. The winner of the first prize will get the rubber detector from 5 yuan, the winner of the second prize will get the mechanical pencil from 3 yuan, and the winner of the third prize will get a book, which will make those students who have not won the prize envy and compete with each other.
If I were a PE teacher, I would teach them to skate in spring, swim in summer, play basketball in autumn and run long distances in winter. When it rains, I will give them a chess set for every four people. When the sun is big, we can go out and play games.
If I were a PE teacher, I would find a classmate with good PE performance as a class representative and organize everyone to jump the long rope every morning. When I rest in middle age, I go skateboarding or playing games with everyone. Occasionally I have Chinese and math classes, so that everyone can learn to play ball with me.
In a word, my dream is to be a PE teacher, play with everyone and be good friends with everyone. I will never scold them, and I will encourage them if their grades are poor.
7. The composition of the future: the car of the future.
So I want to invent a future car, which is environmentally friendly, energy-saving and safer. I think the future car should be driven by solar energy, so the body of the future car should be equipped with solar cells.
As soon as the sun shines, the car will have energy, not only driving fast, but also not emitting black smoke. If it rains, you can use the electricity usually stored in high-energy batteries.
Many people can't drive. In the future, cars will drive automatically. Cars can not only identify their own roads, but also automatically avoid various obstacles, automatically identify traffic signals, and automatically stop in case of emergency to ensure the safety of passengers.
Each car is equipped with a computer with detailed maps of all parts of the country. Where the owner wants to go, as long as he clicks the place with the mouse, the car will find the best route and arrive in the shortest time.
Nowadays, the quality of cars is not high, there are too many accidents, and cars often break down on the road. In the future, cars can be automatically maintained and repaired.
Once a fault occurs, the car will start an emergency plan and automatically search for maintenance points through satellites for maintenance. In this way, passengers are much more relaxed.
This is a dream of mine. I must learn my skills well and realize my dream. The Book of the Future 2 100, with the rapid development of science and technology, many new things appeared in our field of vision and changed our lives.
You see, there are large-screen HDTV as thin as paper, talking rice cookers, button-sized mobile phones, shoes that can change color and adjust temperature ... What interests me most are all kinds of books with strange functions. The bookstore of the future is like an open book.
On the front curtain wall, you will see many colorful, vivid and interesting pictures, introduce newly published books to passers-by and attract people into the temple of knowledge. When we walked into the store, the first thing we saw was the "Baby Reading" area. Let's see what books we have.
There is a book called Fruit Doll, which introduces fruits from all over the world. These paintings are brightly colored. More strangely, this kind of book will give off fragrance. If you turn to the picture of an apple, it will naturally smell like an apple. If you turn to the picture of grapes, you can smell the smell of grapes ... this book with all colors and flavors makes people want to put it down and drool. Open a book called Interesting Animals, and you can not only see all kinds of animals, but also hear their cries. You said, this is a book, can the baby not like it? After the "baby book" area, I came to the "children's book" area, where the books are more interesting.
Open Andersen's fairy tales, melodious music floats around, bringing you into the dreamy fairy tale world. You can choose to read words, listen to stories told by grandpa and watch cartoons. It's amazing. Open the children's song. It doesn't matter if you don't know those tadpole-like staffs. Just click the title of the song and the melodious song will float out. You can learn new songs easily.
The most interesting book is about calligraphy. It has three modes: imitation, improvement and appreciation. If your handwriting is scrawled, choose the imitation mode in the book. When you write, your pen will never run around again, and you will write beautiful words like copybooks. After the "children's books" section, you will enter the "adult books" section.
There are many uncles and aunts who concentrate on their studies. If you want to learn from chefs, open a book about cooking and introduce you to various delicious cooking methods in the form of animation. You can smell the fragrance of the dishes.
If you want to learn other skills, you can easily learn them by finding the corresponding books. There are many wonderful books in the future society, such as metamorphosis books, edible books and wearable books ... Do you still want to know their secrets? (Home of the Future) The earth in 2050 is a beautiful earth, which has been rated as a "beautiful planet" by the king of the universe for several years in a row. "
I am a member of the earth. Get up every morning and put on a universal suit.
This is the greatest invention of this century! This kind of clothes contains nanofibers, which can adjust the temperature according to the weather change. It can make you feel cool in hot summer and warm as spring in cold winter.
After washing and grooming, come to the kitchen. The kitchen will measure all the nutrients you need today according to your steps and make you a "universal pill" immediately. This is a highly nutritious food, which ensures the nutrition of human body for one day.
Everything is ready, board the "Happy" spacecraft and go to work in the electronic building. On the road, the spacecraft is driving on a wide road with novel gardens and neatly trimmed trees on both sides.
Trees give off oxygen, flowers give off fragrance, and the two gases are mixed together. There is an unspeakable fragrance that intoxicates me ... The place where I work is located in the city center. The office building is a very trendy building, a bit like the famous French building-the Eiffel Tower.
The external material of the whole building is silver-gray solar panels, which can absorb the heat of the sun and then pass through the electric energy conversion station in the building. Part of the electric energy is supplied to the daily work of the whole building, and the other part is input into the electric energy storage. If it is rainy and electricity is needed, the electricity in the "warehouse" can be transferred out, which is enough for the whole building. After a busy day in the electronic building, I drove home in the "Happy" spaceship. I sat on the sofa and suddenly realized: hey, if you want to make many articles that benefit the country and the people, you should work hard and study hard from an early age! The future world is now 3002. As time goes by, I will become a scientist. You will definitely ask, "1000 years, how did you survive?" In fact, I have studied a medicine called "fairy medicine", and you will probably understand it after listening to this name.
The ingredients of this elixir are (Angelica sinensis, Polygonum cuspidatum, snake gall, spring worm, ginseng, Saussurea involucrata ...) ... these are just some of the medicinal materials. It takes endurance and perseverance to make it, so the price is ... of course expensive! Ha ha! Stop joking and let me tell you something about the future! The future is the nano-era, and you can reach it if you think about it.
8. future blackboard composition 350 words now, teachers always write on the blackboard with chalk. This is a waste of time and chalk. Therefore, I want to invent a blackboard that automatically displays words. This blackboard is made of unbreakable glass, like a big screen. On the left of the blackboard, there is a microcomputer. There are three buttons on the computer: the first one is the enter key. Press it to display the words that the teacher wants to write on the screen. There is a theme adjuster next to this button. In Chinese class, the teacher puts the head of the character adjuster on the Chinese language, so that the input characters become clear and neat Chinese characters. Similarly, when you are in math and English classes, you can display numbers or English. The second is to clarify the key points. Its function is to clear up typos. The third is the zoom-in and zoom-out key, which can enlarge the displayed text with one click and double-click to reduce the displayed text. Even nearsighted students can take off their glasses and see the words on the blackboard clearly. There is a hidden radio on the right side of the blackboard. This radio is connected to a hidden computer by ultrasonic waves. If the teacher wants to write something, just say it, and then press enter, the radio will be transmitted to the computer quickly through ultrasonic waves, and what he wants to write will come out.
How's it going? Not bad! I think the teacher will smile from ear to ear when he has this blackboard in the future, because I invented it.
