Growing up, I have experienced many things, big and small, but I still remember very few things. That day is a very special and important day for me-my "Shell Breaking Day" is also my birthday. I get up early to get ready. Finally, at the appointed time, all my friends arrived one after another. One after another "Happy Birthday" came to my ears, and one birthday present was put in my hand. These gifts are beautifully packaged and obviously bought, which really dazzles me, but I prefer my own gifts because I am more sincere. When the party was about to start, I found that a person who was very important to me-my best friend-Chen Xiao had not come yet. It's time, so I'll start the party first. I thought: Chen Xiao will definitely come later, and she won't break the agreement. The party ended and all the friends left, but Chen Xiao still didn't come. "How can she break her promise? Even if something happens, you should call me and let me know! " The more I think about it, the angrier I get. At this moment, the doorbell rang in a hurry. "Who will it be? This can't be ... "I opened the door, it was already morning! "Pie, has the party started?" Chen Xiao asked breathlessly. "start? It's over! You are more than an hour late! " "More than an hour?" Chen Xiao looked at his watch. "ah! It turned out that my watch stopped! " I am angry and funny: "You should always call if you have something!" "I ... I ... I'm sorry!" Chen Xiao handed a humble paper box and turned to go. "Wait, this is ..." I asked curiously. "This is a gift I just made for you!" I see. It turns out that Chen Xiao has been making gifts for me, but her watch has stopped. She didn't think the party had started, so she was late. It's not her fault. "Will you accompany me on my birthday?" "You ... good!" Chen Xiao jumped up with joy. We had another happy birthday. After Chen Xiao left, I opened her present. That's a pen container. It's not as beautiful as the one I bought, but it's made with heart. You must have heard of birthdays, but you have birthdays twice a day. Have you ever heard of them?
"Recommend a good book" 500-word composition
The novel Robinson Crusoe has always been loved by students. Curious about this book, they walked into it with the protagonist.
The whole article focuses on the story that Robinson overcame many difficulties through his own labor on a desert island, finally overcame the harsh environment, and returned to his hometown with the aborigines on Friday and lived a happy life.
What I admire most is not Robinson's diligence and courage, but his amazing psychological endurance. It is conceivable that a lonely living person, who has lived alone on a desert island for more than ten years, has no company, and it is impossible to even talk to a person for a while. There are no houses and rice fields on the whole desert island. He has to create a world by his own efforts.
In fact, Robinson is also an ordinary person, and he has no amazing skills to struggle for a long time in this bleak environment. But he resisted the blow and showed extraordinary psychological endurance. In order to regain his courage, Robinson wrote a huge difference table and analyzed all the possibilities. Whether it is out of negative or positive, it enables him to calm down, get rid of the days when he can only dream, and learn to look for hope from despair, so as to face the reality bravely and improve the status quo.
But compared with Robinson, our modern students' psychological endurance seems to be too poor. Don't say that you have experienced such hardships like Robinson, even some sesame-sized things will be easily knocked down by him. It is often learned from newspapers and TV that many students run away from home or even commit suicide every year, often because they quarrel with their parents, their exam results are not satisfactory, or they are severely criticized by teachers. Some people even hold the momentum of "dying". In fact, this is a manifestation of psychological fragility. How ridiculous and pathetic this is!
In fact, everyone will often encounter unsatisfactory things in life. When I was in primary school, I was once criticized by my teacher for a little thing. Because I thought my intention was good, and I felt unspeakable grievances. I am always absent-minded in class these days, and I can't wait to escape from this abyss-like school and go as far as possible. It's ridiculous to think back now, because we were young and had poor psychological endurance, so we came up with so many absurd ideas. In fact, from another angle, it is not a bad thing to be criticized by the teacher. Although we are wronged, if we are more careful, we will not be misunderstood, so when we encounter something unsatisfactory, we will look on the bright side and there will be many unexpected happiness waiting for you to harvest!
I once heard a famous person say that suffering is an abyss for the weak and an insignificant stepping stone for the strong. This sentence inspired me to keep up with the bright future of my life. Yes, nine times out of ten, life is not satisfactory. As long as we adjust our mentality, we can sweep away all our troubles and turn difficulties into a driving force for progress. When difficulties come, we should seriously and calmly analyze the causes of this incident and eliminate and overcome it in a targeted manner, instead of just venting and unrealistic dreams. This is not only futile, but also a waste of time and energy, which will cause you more harm.
As middle school students in the new era, we should have good psychological endurance, so as to meet every challenge in the future with confidence and complete our work well!

Interesting experiment
Today, I came to my father's office panting. My father took out a lot of strange things and said to me, "Li Jian, do you want me to give you an interesting experiment?" I said, "Good! But what do you use to do it? " Dad pointed to the pile in his hand and said, "This is it!" " "I said," huh? No way! How is that possible? What experiment are you going to do? " "Eating Fire Experiment" said with a sly smile on Dad's face.
I saw my father fiddling with the experimental tools. Then, he took out a bottle full of alcohol and a peeled Sydney and soaked it in alcohol. Then he picked up a candle and lit it with fire. Then, he took out the Sydney soaked in alcohol and lit it with a candle. Then, the important moment came, and a miracle happened! Dad swallowed the burning Sydney! ! I let out a cry, "wow! Dad, are you going to die? Aren't you scared? Oh, my God! Never have an accident! " I thought with prayer and impatience. A few minutes later, it was amazing! Dad is fine. He chews happily and says it's delicious. How strange! I asked my father, "Dad, aren't you afraid?" Have you developed a mouth that is not afraid of fire? "I said in surprise. Dad told me, "It's nothing, as long as you keep your mouth shut and don't breathe when you put the pear in your mouth." How's it going? Would you like to have a try? " 。" I said, "Good!" Dad repeated the action just now, and then brought me the burning Sydney and said, "Wait a minute, eat when I tell you to eat, and chew when I tell you to chew, remember!" " I looked at Sydney, which was still burning, and said in fear, "All right." So, I took Sydney and ate it. My father ordered me to put it in my mouth at once. After a few minutes, my father said, "Chew." So, I started eating, ah! It is really delicious! And I don't feel any pain at all. I thought it was really strange, so I asked my father. Father said, "Everyone knows that fire depends on air, because when we eat it, we immediately shut up and stop breathing. At this time, there is no air in our mouth, and the fire will naturally go out, and it will be fine! "
Ah! It turns out that there are such wonderful experiments in the world!
Telegraph, telephone and electric light are so common and common in today's advanced technology that no one will be surprised. But do you know how important these things were to people at that time and how ecstatic they were? Humans thus remembered their inventor-Edison.
Edison, known as the "King of Invention", is a famous American scientist and inventor. In his life, there were 1328 inventions registered in the patent office alone. How can a person who has only studied for three months have so many inventions? I think, if you have heard the story of "Edison incubating chickens", you will understand that his success stems from strong curiosity.
1847, Edison was born in a merchant family in Milan, Ohio, USA. Edison showed great curiosity when he was very young. Whenever he sees something he doesn't understand, he grabs the adult's skirts and keeps asking questions, insisting on asking ugly questions.
One day, he pointed to the hen that was hatching eggs and asked his mother, "What is the hen doing sitting under the egg?" Mother said, "Oh, that's a chicken!" " "In the afternoon, Edison suddenly disappeared, and the family was anxious to look around and finally found him in the henhouse. It turned out that he was squatting in the chicken coop, and * * * put down a lot of eggs to hatch chickens! When his parents saw it, they were so distressed that they had to pull him out and wash his face and clothes. Another time, when he saw birds flying freely in the sky, he thought: Since birds can fly, why can't people fly? So, he found a kind of powder for his friends to eat, in order to let them fly into the sky. As a result, the little friend almost died, and Edison was severely beaten by his father.
Finally, Eddie grew up to 8 years old, and his parents sent him to a rural primary school, thinking that he could go to school safely from now on. Who knows, he still loves to get to the bottom of it, and often asks the teacher dumbfounded and embarrassed. Once in an arithmetic class, the teacher wrote "2+2=4" on the blackboard. Edison immediately stood up and asked, "Teacher, why is 2 plus 2 equal to 4?" This question puzzled the teacher. He thinks Edison is a troublemaker and always disagrees with his teacher. So Edison attended classes for three months and was driven home by the teacher.
Edison's mother is a great mother. She didn't blame her only son for being driven back. Instead, he decided to educate the child himself. When she found Edison curious and particularly interested in physics and chemistry, she bought him books about physics and chemistry experiments. Edison started the experiment on his own according to books. It can be said that this is Edison's enlightenment education in scientific inventions.
When he grew up, Edison learned radio transmitting and receiving technology. He got a job as a night shift operator at Stratford Railway Sub-bureau. According to the regulations, the night shift operator must send a signal to the train service director every hour after 9 pm, no matter what happens. In order to have a good rest at night and study and invent during the day, Edison designed a telegraph that can automatically send signals on time. This is the prototype of the telegram.
Soon after, he improved the telegraph. After many tests, a new type of telegraph was successfully trial-produced. Edison looked at the machine he invented and smiled with relief.
It should be said that every invention of Edison is closely related to his curiosity. After inventing the telegraph, he began to do telephone experiments. He found that the diaphragm in the microphone could vibrate with the sound, so he observed it carefully and made a detailed record in his notebook. Thus, a "talking machine" was made. When people heard the news, they all came to watch and called him "the greatest inventor". Therefore, curiosity is a prerequisite for a person to succeed and show his wisdom.
Not only famous scientists need curiosity, but we ordinary people also need curiosity to learn knowledge and achieve something. 199 1 In July, Guangming Daily Science and Technology Department conducted a questionnaire survey on 1 18 middle school students who won the National Youth Science and Technology Invention Competition. In the column of "Your main psychological characteristics", 92% of the students wrote "Strong curiosity". He Ji, a teenager from No.1 Middle School in Daoxian County, Lingling District, Hunan Province, couldn't help wondering when he went to the henhouse to get eggs one day: How can eggs be big or small? Is the big head first out of the matrix or the small head first out of the matrix In order to find out this problem, he rushed home immediately after school every day, squatted by the chicken shed and observed quietly, sometimes even forgot to eat dinner. After more than two months, He Qi finally found that the egg came out first. To this end, he wrote a paper, which was praised by many biologists. His discovery is actually a new discovery that has not been recorded in bird literature.
Being a talent requires curiosity, but being curious doesn't mean that you will become a talent. If you want to achieve something, you still need to work hard. Curiosity is like a seed. Without it, a towering tree cannot grow, and people without curiosity cannot invent or create anything. After the seeds are sown in black soil, they will gradually break through the soil and grow into pillars through watering and cultivation. With curiosity, sweat and hard work, you will certainly become a useful talent. Dr. Li Zhengdao, a famous contemporary physicist, said: "Curiosity is very important, and curiosity is indispensable for science. The reason is very simple. Only curiosity can ask questions and solve problems. The terrible thing is that you will not ask questions and will not take the first step. " Because curiosity is so important, many people call it the first virtue of successful people. For an ambitious and eager teenager, curiosity is the most precious thing.
Not so good, please forgive me! ! !
My father wrote 800 words.
On Sunday, I asked my brother to accompany me to learn to ride a bike. I am riding a bike, and my brother is holding the bike hard behind me, lest I fall down. However, I still wriggled like a drunk. Get on the bus for a while and get off the bus for a while. This was repeated several times. I thought: I must have learned to ride a bike. So, I told my brother to let go. However, I didn't expect that the car crashed into the ground as soon as it turned a corner, which was completely out of my control. I was really surprised. In the field, I happily took a sewage bath. But falling down at school didn't discourage me. In the afternoon, I will ask my brother to come out and practice with me. After coming down a few times, I seem to be able to ride a little. My brother let go and I rode it twice by myself. I'm so happy! Going home, I said to my father, "Dad, Dad, I can ride a bike." Mom and dad both touched my head and smiled happily. Author: Kong Zhejiang Yueqing Nantang Central Primary School Grade Two Instructor: Zheng.
Learning "Wu" has influenced me (composition)
Reading has influenced me.
In my bedroom, you can't see the toys that ordinary children like, but "Confucius moved-books are everywhere". There are books on the desk, bedside, wardrobe, floor and windowsill. My mother said I was a nerd. I am very happy with this name, and I also like to sleep with a book in my arms.
When I was four years old, I began to read Baby Pictorial with curiosity, from which I learned a lot of knowledge, such as "Bugs Build Houses": Bugs asked frogs, water spiders, ducklings and snails why they were not afraid of rain. The frog said, "My skin needs water to moisturize." The water spider said, "My hair won't stick to water." The duckling said, "I am not only hairy, but also oily, so I am not afraid." The snail said, "I have a shell!" " "After listening to the snail, the bug understood, vomited a cocoon and fell asleep. From then on, I understood that every small animal in nature has a magic weapon to protect itself. Gradually, I fell in love with reading and learned the benefits and fun of reading.
When I was seven or eight years old, I began to read legends and fairy tales with the help of a dictionary. I have read that Snow White is dancing on the green grass in white. I read that the frog prince was wearing a light green military uniform and jumping around happily in the forest ... When I read the article about the little fox in Grimm's fairy tale, I read that the prince went to find parrot oil to rule the king's father's eye disease. With the help of the little fox, the prince got a princess, a sword, a BMW and a beautiful parrot, and exposed the conspiracy of his two brothers and lived a happy life. After reading it, I started another idea. If there is no fox, how can the little prince find parrot oil? What will the adventure be like? I gave my own imitation and adaptation story to the teacher, who took it out as an excellent article and read it to the students. From then on, I began to write my own stories and make up my own fairy tales.
Since I was nine years old (I'm eleven now), I've enjoyed reading famous books and some profound science fiction novels, such as Romance of the Three Kingdoms, The Mummy's Resurrection, The Wizarding World and so on. I am immersed in the world of books all day, with endless joy, joy and sadness: sometimes I can't help applauding when I see the happy ending at the end; If the story is tragic, I will burst into tears, and my mother often thinks that something has happened to me. When reading Romance of the Three Kingdoms, I appreciate Zhuge Liang's "Three Jade" best. This time, I really appreciate Kong Ming's cleverness, and I also understand that a man should be open-minded, "the prime minister can punt in his stomach", otherwise a hero will not escape a tragic end.
Reading has broadened my knowledge and made me know that the world is wonderful. Reading has greatly improved my writing. It can be said that if I didn't study hard, I wouldn't have the current writing level. Reading makes me understand things and know what is right and wrong. Reading gives me self-cultivation. I will help my mother fetch water and wash her feet. I will let my mother go first when I walk, so now my mother often praises me as "a good gentleman!" " "
In this life, I will remember grandma Bing Xin's words: study hard, read more, study hard.
Reading has influenced me.
Although the students saw only an ordinary book, I learned a lot from it. It gives me strength, knowledge and motivation to move forward.
Reading makes people wise. I learned from "100,000 Why" that boiled eggs should not be soaked in cold water, but in hot water. Cooked eggs, the outer protective film has fallen off, put in cold water, bacteria in cold water will go in, and it is unhealthy to eat.
Reading makes people wise. I read a book called Harvard Girl Liu Yiting. Liu Yiting's growth, reading and literacy are recorded in this book. I envy her! I think: If I have her skills, I will learn from her. Now, I am taking the time to learn English, and I am determined to study at Harvard.
Reading makes people rich. It is said that Bill? Gates finished reading the online encyclopedia at the age of nine and founded Microsoft when he grew up, becoming the richest man in the world. As the saying goes: the book has its own golden house. Have you seen Bill? Gates knows that reading is at least not bad. China is still relatively poor and backward. In order to catch up with the developed countries and live a rich life, I will study for the rise of China, create wealth with knowledge and change my destiny.
Reading improves humanistic quality. Some people stop studying, swear, swear and be despised when they don't graduate from junior high school; Some people are highly educated, well-read, polite and praised. Compared with the two, everyone is willing to be a cultured person. Of course, I am no exception.
Ah, reading has a great influence on me! There is a road in the mountain of books, but there is no limit to learning the sea. Reading benefits people a lot. I read page by page and succeed step by step. ...
The composition of Lu's dream
There is no class today. I went to play with my parents. On the way, I chatted with them about the story of Chang 'e, which was very interesting. After playing for a day, I came home, rested in bed, and fell asleep unconsciously. I was sleeping when I heard someone knocking at the door. I got out of bed and opened the door. I saw my shadow standing outside the door. I thought I was wrong. I rubbed my eyes and saw that it was my shadow. It moved, said nothing, and did the same thing. At last, I understood that there was a spaceship parked behind the shadow. "Hey, what is this?" I asked the shadow curiously, and the shadow could not speak. His action was to get me on the ship. I hesitate, what if it is a bad person! After a while, the shadow saw me motionless and pulled me to the spaceship without hesitation. I was just about to call my mother, but there was no sound in my throat. How strange! I fell asleep with fear. I don't know what happened back there. Then I heard a slight cry: "wake him up", and then a man came up to me and pushed me slowly to wake me up. I slowly opened my eyes and found this strange place. Open your eyes and drive to a palace. How beautiful! Where is this? I asked myself doubtfully, and suddenly I saw my own shadow. I asked him, "Where is this?" It's strange that he doesn't talk. "Welcome to visit the moon! Hello, children! Hello! I am WU GANG, welcome to the moon! " I was awakened by a sentence and found that this is actually the moon. It's unbelievable. "Go, go in and have a look." I followed him into the palace. There is a big and beautiful osmanthus tree in front of the palace. I went in and said, "Wow." I can't help but wonder, "It's beautiful!" "Ha ha, this is still a part. Come and visit. " I followed him into a room, "Wow!" I can't help but marvel again. There is a big garden with the sky and all kinds of animals playing in it. I suddenly remembered Chang 'e, and I asked him, "Where is Sister Chang 'e?" His calm face immediately appeared a little panic. He said, "She is not at home now. If you want to see her, you have to wait two days. "That's strange. I was about to see another room when I suddenly said, "Xin-er, get up quickly. You haven't had dinner yet. Why did you fall asleep? " I opened my eyes in horror, "huh? Why are you at home? Isn't it on the moon? How can you go home again? "I have a question mark in my mind. What is this? " You dreamed again, so you slept for a while. What good dreams did you have? "ouch! What a shock! It was a dream! Then why does Uncle WU GANG have that look? What's the reason? Did something happen to Sister Chang 'e? Dizzy! What the hell is going on! I feel dizzy thinking about it! Hey! No! Sleep! ! ! !
The Story Composition of "Qi" Celebrities Discovering Truth
Fleming is a British scientist and the discoverer of penicillin. When Fleming was a military doctor, he saw many soldiers die painfully because of bacterial infection in wounds. He was determined to find a medicine to treat diseases caused by bacteria. He found penicillin in the experiment. This magical medicine has saved countless lives, which is the success of his efforts with several scientists.
Fleming won the Nobel Prize in Medicine. He said: "Opportunities are only reserved for those who are prepared."
2 1895,165438+1Friday, October 8, this afternoon, Roentgen did experiments in the laboratory as usual. He first wrapped a crookes discharge tube in black paper, blackened the room, connected the induction coil, and let the high voltage discharge pass through the discharger. There is no light leakage on the black paper, and everything is normal. He cut off the current and prepared to do experiments every day, but in the blink of an eye, there seemed to be a flash of green fluorescence in front of him, and then it turned black. The discharge tube was wrapped in black paper just now, and the screen didn't stand up. How can there be fluorescence? He thought he must have observed this mysterious fluorescent fire in a dark room all day, formed a habit and had hallucinations, so he repeated the discharge experiment. But the mysterious fluorescence appeared again. With the ups and downs of the induction coil, a small pale green cloud suddenly floated deep in the night sky and moved evasively. Roentgen was shocked. He grabbed the match on the table and scratched it with a crack. It turned out that a small platinum barium cyanide screen stood nearly one meter away from the workbench, and the fluorescence was emitted from here. But cathode rays cannot pass through the air more than a few centimeters. How can they make this surface flicker on the screen nearly one meter away? Is it an undiscovered new ray? Thought of here, he was thrilled. He is 50 years old this year. He worked in this dark room without winter, summer and night, and tried his best to explore the mysteries of nature, but he never saw a glimmer of light. Is this fluorescence a sign of fate? He excitedly raised the screen and moved the position in tandem, but the green light would never go out. It seems that this new ray has a strong penetrating ability, which has little to do with distance. So can it penetrate anything other than air? Roentgen took out a playing card to block the ray, and the light still appeared on the screen. He changed to another book. Although the screen is not as bright as it was just now, it is still very bright. He changed another thin aluminum sheet, and the effect was the same as that of a thick book. He changed a thin piece of lead, but there was no light-lead can actually cut off radiation. Roentgen was so excited that he kept changing bomb shelters. He tried almost everything he could touch. At this time, the workmates came in to urge him to eat. He promised casually, but didn't do it. Although the experiment in hand stopped, he was still staring at the screen. Now it is certain that this is a new kind of ray, but what is its use? What shall we call it for the time being? It is really an unknown number. Ok, let's call it "x-ray" for the time being.
