Whenever I touch the scar on my left hand, I always think of that unforgettable lesson.
On the morning of the summer vacation in the big class, mom and dad have to go to work. Before going out, they warned: "Don't touch dangerous items such as scissors and knives at home, and stay at home." I said yes, but I thought to myself, I am not. No sooner had they left than I pretended to walk around.
I thought they had gone far, so I took out scissors, paper and pencils to cut the graphics. I first drew a figure on the paper, took out my scissors and prepared to cut them. I cut it slowly for a while, and then I feel nothing, so I cut it quickly, humming a tune while cutting my mouth. I shook my head, very proud. Suddenly, my hand cramped. Ah! I made a deep and long cut in my hand, and the blood flowed straight out. I was scared to tears. My crying alarmed my neighbor, Grandma Zhang, who knocked on my door. When she saw me, she blamed me and my parents, and then called my dad.
When my parents came back, they saw my hand, clothes and blood on the sofa, which scared them. Regardless of the willy-nilly, he was sent directly to the hospital for dressing and kept crying.
What an unforgettable lesson this is! From then on, I kept in mind my parents' advice and never dared to play with dangerous things again.
Humans have found something from dragonflies and whales, but flies have inventions that everyone hates! Entomologists found that the fly's hind wings degenerated into a pair of balance bars. When it flies, the balance bar vibrates mechanically at a certain frequency, which can adjust the movement direction of its wings. It is a navigator to keep the balance of flies. Based on this principle, scientists have developed a new generation of navigator-vibrating gyroscope, which greatly improves the flight performance LlJ of the aircraft, enables the aircraft to automatically stop the dangerous rollover flight, and automatically restore the balance when the body is strongly inclined, even when the aircraft is in the most complicated sharp turn. The fly's compound eye contains 4000 single eyes that can be imaged independently, and almost 360 can be seen clearly. Objects within range. Inspired by the fly's eye, people made a fly's eye camera consisting of 1329 small lenses, which can take 1329 high-resolution photos at one time. It is widely used in military, medical, aviation and aerospace fields. Flies have a particularly sensitive sense of smell and can quickly analyze dozens of smells and respond immediately. According to the structure of flies' olfactory organs, scientists have converted various chemical reactions into electric pulses, and made a very sensitive small gas analyzer, which is widely used in spacecraft, submarines, mines and other gas components, making the safety factor of scientific research and production more accurate and reliable. Nature is really a good teacher for human beings!
The 300-word composition of the fourth-grade students is particularly eye-catching from March to Mid-Autumn Festival, so getting together with their families to enjoy the moon and eat moon cakes has become the fastest joy and happiness on Mid-Autumn Festival night.
On the night of Mid-Autumn Festival, my family and sister sat around the balcony early, chatting and waiting for the moon to rise. After waiting for a long time, finally, a big round moon emerged from the dark clouds and hung in the night sky. At this time, the moon gave off golden light and sprinkled it on thousands of households. In this charming moonlight, my sister and I are happily eating moon cakes and playing guessing games.
Mother suddenly suggested: "let's play solitaire with the word' moon'!" As soon as my mother's voice fell, my father shouted, "There is such a bright light at the foot of my bed. Could there be frost already?" "I am not to be outdone to see my father say this most familiar poem:" On a frosty night, Jiang Feng is worried about sleeping. " Hearing this, my sister said unhurriedly, "People have joys and sorrows, and the moon has ups and downs." Then, my mother said confidently, "The moon is full of the sea now, and the horizon is * * *." ..... After two rounds, we couldn't think of it. It seems that I have to recite more poems!
Unconsciously, the moon rose higher, it was round and white, like a big jade plate hanging in the dark night sky, emitting bright moonlight. I took out my telescope and looked at it carefully, as if I saw the beautiful scenery of Chang 'e and Moon Rabbit dancing. At this time, I had a question-why did Chang 'e live in Guanghan Palace? Then, my sister and mother told me the story of the Goddess Chang'e flying to the moon.
On this beautiful Mid-Autumn night, I not only saw the beautiful moon, but also learned more knowledge. I love this happy Mid-Autumn Night!

I wanted to listen to stories when I was very young, but my grandmother had a bad culture and would only tell me some local stories. Once, grandma told me a story about grandma wolf. The story goes something like this: A long time ago, a wolf wanted to eat a child, so he dressed up as a grandmother. At night, he coaxed the children to sleep with him, but only one person was allowed to sleep with him. Grandma Wolf prefers to eat little boys. In the dead of night, grandma wolf will show her ferocious face and eat her little nephew, but one night, grandma wolf can't finish eating a little boy, leaving her fingers and fingers.
From then on, as long as I don't want to sleep, my father will knock on the bed a few times and say, "Don't sleep, grandma wolf is coming, so hurry to sleep!" " "And I'm really afraid grandma Wolf will come and fall asleep at once.
Now think about how ridiculous and childish I was at that time, and I was cheated by grandma Wolf. Everyone has a bittersweet growth story, and grandma wolf's story makes me unforgettable all my life, so what is unforgettable for you? Do you want to share it with us?

Look, that's children and adults picking fruit in the orchard. Apple began to do magic through the beautiful aunt Qiu. From cyan to red. So beautiful Qiu Guzi and children can't help kissing apples. I didn't expect Apple to be shy and start to turn red. As red as a sexy red rose in spring, it is very attractive. The apple bloomed happily, and it rained a beautiful maple leaf rain for Qiuguzi. They circled around their enemies like colorful butterflies. Qiuguzi was happy, so she gave the earth a piece of golden rice, so that farmers could have plenty of food and clothing, stop being hungry and cold, let the maple leaves return to their roots and embrace the earth again.
At this time, the children's laughter and slapstick are linked together. Ah, I want to thank the beautiful aunt Qiu. In this season, you let us not only harvest fruits and rice, but also harvest happiness.
On my way home from school one day, I suddenly saw the glass of my neighbor grandpa Zhang's house broken. It turned out that the neighbor's children played with football. I think: If Grandpa Zhang's glass is always not repaired, how cold it will be when it is windy and rainy! So I hurried home. When I got home, I took out the ten dollars I had worked so hard to save from the piggy bank and hurried to Grandpa Zhang's house.
Breathing heavily, I came to grandpa Zhang's door and knocked on the door. Grandpa Zhang opened the door. I said to him politely, "Grandpa Zhang, your cup is broken. Please take this ten dollars to repair it! " Grandpa Zhang waved his hand in surprise and said, "That's very kind of you, son." You didn't kick this cup. How can I ask you to pay? "I insisted," grandpa, it's getting colder and colder. If you don't repair the glass, you will catch a cold. This is a token of my appreciation. Please accept it quickly! " Grandpa Zhang excitedly took my hand and said, "son, you are so sensible!" "Come on, grandpa is also an old fan. I have been picking up a football. Although it is old, it can still be played. I will play for you! " I said evasively, "Grandpa, this is your souvenir. You still keep it! " ! You don't have to give me anything, this is what I should do. "Say that finish, I ran home.
When I got home, I told my mother about it from beginning to end. My mother gave me a thumbs-up and said, "Good boy, you have grown up!" " "

There are many interesting things in the process of growing up, which made me understand some knowledge and truth. The happiest thing is that I learned to ride a bike.
I remember one day, I saw others riding bicycles, free and happy. So I told my mother with anticipation that I wanted to ride a bike. Mom quickly agreed. As soon as I got my bike, I felt that riding a bike was as simple as eating. But as soon as I stepped on it, the bike tilted disobediently. I jumped down at once, thinking: Hum, this damn bike is really heartless, trying to make me fall over a dog and chew the mud. No way! I can't believe I can't do this. I grabbed my bike again and jumped on it with all my strength. The result was still the same. I sighed helplessly in my heart: it really looks easy, but it's hard to do!
I had a brainwave and called my personal trainer dad. He held my back seat until I sat down, and then counted loudly: "one, two, three!" " "After counting, I pushed my bike forward. With the help of my father, I immediately set foot on the bike. Time and time again, I finally found the trick of balance.
Bicycle, finally learned! This is a story of my growing up. I understand that doing anything requires hard work and practice.
