The magical fourth-grade composition 1 Future technology is changing everything and making people's lives more convenient. Let's step into the future classroom and explore the high technology of the future classroom together.
In this classroom, every teacher and every student has an ID card around their necks. When they enter the classroom, if they don't have or don't wear identification cards, the door of the classroom will give an alarm and automatically open the protective cover. The glass in the classroom is not only super explosion-proof tempered glass, but also a kind of split glass. If someone breaks one of them, the glass around it will automatically split into another glass and stick it on the broken glass.
Let's talk about the interior of the classroom. The blackboard in the classroom is also a kind of voice control. You say "clean the blackboard" and it will fly to clean the blackboard automatically. The desks in the classroom are also amazing. You just need to put all the stationery in the desk. You just need to say what stationery you need in class, and it will have a small mechanical arm to put the stationery you need in front of you, and it will put it back in place after class.
How's it going? Is this classroom amazing? If you have a fantastic brain hole, you can also have a classroom like this.
Hello, everyone, my name is Dee Chun Yan. I am a little girl who loves fantasy. In my dream world, we have a magical classroom. What's wonderful about it? Listen to me in detail.
First of all, our classroom has an automatic door, which can automatically identify the students in this classroom, not the students in this classroom, and can't open it. In the future, there will be many bookcases in our classroom, which can automatically push his favorite books for the students standing in front by scanning. This bookshelf seems to have mind reading. The window is also very capable. It can detect the indoor and outdoor temperature difference, automatically switch on and off, and adjust the indoor temperature to the most comfortable environment for human body. Warm in winter and cool in summer, just like a big air conditioner. The blackboard in the classroom is no longer like a blackboard and a whiteboard, but like a computer monitor. Every text on the blackboard is not in the form of words, but in the form of objects. I believe everyone has gone to the cinema to watch 3D movies. Our classroom can also become like that, with the feeling of "being there", learning has become relaxed and happy.
How's it going? After listening to my introduction, do you want to own this classroom? Although this is only my "fantasy", I believe that as long as we study hard and study hard, it will definitely appear in front of us and serve us!
The magical fourth grade composition 3 "Wow, wow!" "It's amazing!" "It's burning, it's burning!" Do you know what we are doing? We are doing experiments. Have you ever seen a handkerchief that won't burn? Let me show you!
The teacher gave us an experiment today. I saw the teacher pushing the table with an unknown liquid in his hand, which was a little cloudy and yellow; There are also two long tweezers, a white handkerchief and a lighter
Let's start the experiment. The teacher first kneaded the handkerchief into a ball, squeezed it into an unknown liquid, and then took it out and wrung it dry. Holding the corner of the handkerchief with tweezers, I smelled a pungent smell of alcohol. The students stared at the handkerchief with their eyes wide open, and the teacher lit it gently with a lighter. Hey, why didn't it burn? The teacher did it again from beginning to end, and it really succeeded this time. The flaming flame swam around like a blue and red fish, but the handkerchief was intact at this moment, as if to say, "It's hot, it's hot!" " "The teacher kept shaking his handkerchief, like cooking for a while, like a music conductor for a while, and then the fire went out. The teacher asked us to guess whether the handkerchief was hot or cold. I thought to myself: of course it's hot, because it's on fire! The teacher asked us to touch it, yeah! Strange, why is it cold? It turns out that the teacher's unknown liquid is half alcohol and half water. The fire is burning alcohol, but the water protects the handkerchief, so it won't burn out.
The experiment is really interesting, and you can also appreciate the mystery of the experiment!
Everyone has his own hobbies. My hobby is fantasy. I have always had a fantasy in my heart, that is, the magical table.
Look at the calendar, March 8, 20xx. I sat in the "green car" and drove to my alma mater. As soon as I entered the school gate, wow! The air is so fresh. The teacher told us that this is a VR358 "air purifier" to clean up the sundries in the air. Then use clean garbage as fuel. When we entered the classroom, we found that the table didn't seem to have changed. He asked the headmaster, "Teacher, why haven't the desks in our classroom been changed?" The headmaster smiled and said, "Haha, what a difference! Its appearance is no different from that of an ordinary table. In fact, this is a VTC687 technical table. " Sitting at the dining table, I feel much more comfortable, as if I were in a hot spring. Open the desktop, the original desktop is LCD screen, open the drawer, the original keyboard and mouse. I want to know why there is no mainframe. The teacher told us that this is a new type of computer. Hehe, there are also puzzle games. The teacher told us that the "learning" system was installed in the computers of the whole school, which was specially designed by China Chang Fei Company for children's teaching. Very useful. Cover the desktop and close the drawer. The teacher smiled and said, "You are opening the table." Opening the table is an "electronic game"! It's still the popular QQ flying car, Ding! The little alarm clock is ringing!
Ha! I haven't woken up yet. Get some sleep.
Magical Grade Four Composition 5 In 20xx, I tried to invent a schoolbag. Next, I will explain the function of this schoolbag to you.
This schoolbag has three functions. The first function is that it has a robot that can zoom in and out. If there are bad people within the range of the owner 100 meters, it will automatically turn on the protection state to prevent the owner from being injured. The second function is that there are machine coins on both sides of the bag. If the owner is ill, he will send the owner to a nearby hospital immediately. If the host's sitting posture is incorrect, he will adjust his sitting posture. If the owner is not at home, it can also help the owner look after the house. You can worry as much as you want. This is the advantage of having it. The third function is that if the owner has a problem, press the button of the schoolbag, and it will become a top tutor to help the owner learn. You can also teach children to learn English, draw pictures and play the piano, so they don't have to make up lessons. There is a magic schoolbag, which saves us a lot of trouble. We can also learn to play happily with magic schoolbags, not to mention how happy we are. This is also the life I yearn for, carrying a magic schoolbag and carefree. I'm really happy!
I hope my wish will come true one day. Students, do you like the three functions of my schoolbag? If you like, let's work together to create a miracle.
Magical Grade Four Composition 6 During the summer vacation, my mother took me to Hangzhou Underwater World. As soon as I came in, I saw many beautiful fish swimming freely in the fish tank. Walking in the cross-harbour tunnel, I saw a big shark upstream of my head. My heart trembled a little, and I felt that the shark was going to eat us.
After crossing the cross-harbour tunnel, we went to the Dolphin Pavilion and watched the wonderful performance of dolphins. Uncle first asked two rabbits to jump in circles, and they jumped flexibly, and then asked the dolphins to kiss the hands of the audience. I put my hand into the railing, and bunny hop got up and kissed me, which made me feel funny and happy.
Then, we also saw stupid clown fish, red butterfly fish, crystal clear fish, lively and lovely tropical fish, which were really varied and colorful! The most striking thing is coral, some like branches, some like willow wicker, with different shapes, big and small, strange and colorful.
Seeing these colorful aquatic animals, I know there are countless mysteries in the world.
On Sunday, my parents and I went to the playground behind the People's Park-"I was busy flying kites and the east wind was blowing."
It's windy this day, and my "Wukong" kite flies high and far, which is the highest I have ever flown, and almost all the lines in my hand are released. Just when I was complacent, a gust of wind blew and the kite fell over. I quickly closed the line, but the kite was still hanging on the branch, which made me feel distressed.
Dad said don't worry, buy me a bigger and better one tomorrow, but I still can't bear to leave my Wukong. How lonely he is alone on the branch. I told my father, "the Monkey King, the Great Sage of Qitian, will definitely come to help me." Mom and Dad say I am whimsical-daydreaming, but I firmly believe that miracles will really happen.
They couldn't beat me and waited with me for more than an hour. Maybe my heart moved me to be a "Wukong". After a gust of wind, "Dad, look, I dropped my Wukong kite! My Wukong kite really dropped ... "I was so happy that my tears fell.
This matter touched me a lot. I didn't know how to cherish the toys around me before. I always throw them away when I'm finished, and my father used to criticize me. Now I finally understand this truth: in fact, they are all my favorites, and I should know how to cherish them.
Now, every time I finish my toys and homework, I will put them back in their original places, just right and carefully.
My parents praised me as a sensible boy.
I finished my meal in the morning and arrived at school early. When I first entered the classroom, I was shocked: huh? How has my classroom changed? The desks dance like lively children. Even the blackboard is fully automatic. It's writing itself and wiping itself. At this moment, a robot came in. Maybe you have guessed. He is our math teacher and teaches Chinese. It's already noon after a lively Chinese class. The teacher pressed the switch and the wall opened. There are three shuttle doors like black holes. The first one goes to the restaurant, the second one to the dormitory and the third one to the playground. Everyone is hungry, and we can't wait to walk through the first door. We don't have to walk at all, just like a crawler conveyor, we arrive at the canteen in the blink of an eye.
In the first class in the afternoon, a robot PE teacher came. The content of this lesson is to learn table tennis. After the teacher finished the main points, we began to practice according to the automatic voice prompt. Unconsciously, the bell rang. This is my favorite school!
Ding, Ding, the alarm clock rang, and mother said, "It's time to get up and go to school." I am in a daze. It was a dream.
There are many small countries in our world, pencil country, book country, microorganism country, desk country … I also found a country, that was in the morning.
On a fragrant morning, I slept soundly. Suddenly, a small voice came into my ear: "Hello! Hey, it's time to get up, it's seven o'clock, or the sun will kill you! "
"Who are you? It's not my mother, why should I listen to you? " I said while sleeping. After a while, it said, "I am your schoolbag!" " Don't you recognize me? ""how is that possible! The schoolbag can't talk. " I said with a grain of salt.
"Don't believe you, get up and watch!" It says. I got up, then looked at it carefully and said, "You don't have a mouth either! How to speak? " "Well, I don't know. When I practiced singing, I found that I could speak human words. "
"Then let's talk!" I said excitedly, "But you have to go to school!" "It said sadly," don't you know? "Today is Saturday." I said, "Have you no brain?" "Of course not! Who told me I was abiotic? "
"ah! I don't have much time to talk. I have to go, but I'll come back to see you. Goodbye! " The schoolbag said, "Don't go, don't go ..."
"You don't go to the bag! Don't go. " "Schoolbag? Isn't your schoolbag here? " Mom said, I got up at once, and then said, "It was a dream." Then I looked at the reading bag and found a note next to it: This is not a dream! I was shocked.
Do you think this is strange?
On Sunday morning, I watched an animated film called Big Face Cat. The big-faced cat ate a magical colored grape, and I thought, what will happen if I eat that colored grape?
Maybe it will become a cube, maybe it will become a triangle. You can let your children build houses or play with them. In math class, let them post a lot of pictures.
Maybe it can become a snake. Snakes can eat mice and protect the crops of farmers' uncles.
Maybe it can be turned into an airplane. Planes can soar freely in the sky, how vast the sky is! Dad can sit on me, and I can take him anywhere he wants.
Maybe it can become a white cloud, how white it is. Mom can sit on top of me, and I will take her to travel to Hong Kong and Italy. You can sit on me and eat whatever you want, so you won't be so tired.
Maybe it can turn into a small flower, how colorful it is! Little butterfly can sleep here every day.
Maybe it can be turned into a river. How clear this river is. There are many small fish that can swim past me.
If I can really become them, that would be great!
Magic fourth grade composition 1 1 Do you have any trees that can purify the air? Yes, none of us have this kind of tree. So, can you invent a tree that you can take with you? I just want to invent a kind of clothes that can absorb harmful gases and release beneficial gases.
This kind of clothes has many invisible holes, which absorb harmful gases such as industrial waste gas, carbon dioxide and automobile exhaust, and release beneficial gases such as smart gas, oxygen gas and healthy gas. And whether it is underwear, coat, sweater or pajamas, it has this function. We can calculate an account like this: China has a population of 65.438+0.3 billion, which is equivalent to a variety of 65.438+0.3 billion trees. There are 6 billion people in the world, which is equivalent to planting 6 billion trees. And this number is still increasing. In a few decades and hundreds of years, there will be 7 billion and 654.38+0 billion people in the world.
This kind of clothes also has a peculiar function, that is, a person only needs to wear one suit in his life. Because this kind of clothes will never get dirty. Will grow with us. You may ask, "How pathetic is it to wear the same clothes all your life?" Don't worry, I have thought of this for a long time. Just put the clothes on your body and say to yourself three times: "I want to wear XX clothes, which is very convenient." You will immediately become the clothes you want to wear, which is very convenient.
A few days ago, we were having lunch. Then my mother came up and said, "I found a strange flower on the osmanthus tree next door." I have seen it on the computer, called' Udubara Flower'. " I'm curious. Let my mother show me. My mother took me to the osmanthus tree and pointed with her hand: "It's right here." As soon as I saw it, something like a beard grew on the back of a leaf of osmanthus tree, which was green in white and thinner than hair. At the top is a bud smaller than sesame, a cluster of about ten. I think: other flowers grow on the branches. How can this flower grow on the back of a leaf? It's amazing!
After dinner, my mother and I turned on the computer to check the information of Udu Mbala flowers. The computer says: Udu Mbala flower is a legendary fairyland flower, and it is regarded as a Buddha flower because it is "blue and white". According to legend, this flower only blooms once every 3000 years, usually at night. Its fragrance is extremely beautiful, and Rosty Yi withers, just like a flash in the pan, which is auspicious and blessed. I looked at the picture, and it was exactly the same as the one on the osmanthus tree.
I'm skeptical. Are there really udumbara flowers in the world? Is it true that flowers bloom once every three thousand years? If it is true, then we are very lucky.
The magical fourth grade composition 13 have you ever heard of boat-fruited Sterculia? Do you know why it is called Boat-fruited Sterculia? Today I will introduce them to you one by one.
Boat-fruited Sterculia looks like almonds and wears a brown coat. Its surface is uneven, like dried bark, wrinkled and very ugly.
Although this boat-fruited Sterculia is ugly, it can make tea. Take out a cup of boiling hot water first, and then put in some boat-fruited Sterculia. At first, Boat-fruited Sterculia dived into the water like a diver and immediately floated up. Slowly, slowly, one end of it cracked and the skin gradually flattened from a wrinkled appearance. After a while, boat-fruited Sterculia became bigger and bigger, like a sponge, like messy hair, like flowers in the water, crystal clear. Finally, boat-fruited Sterculia was soaked. At this time, a fragrant smell came to my nose, and I suddenly felt refreshed after taking a sip.
This boat-fruited Sterculia also has a peculiar effect: clearing away heat and moistening lung, relieving sore throat and detoxifying, and relaxing bowels. It can also be used for hoarseness due to lung heat, dry cough without phlegm, dry throat pain, heat constipation, headache and red eyes. It's really great!
Next, I'll tell you why it's called Boat-fruited Sterculia: It's called Boat-fruited Sterculia because it is like a sponge when it meets water.
Boat-fruited Sterculia is really a good thing!

The magical fourth-grade composition 15 is in the sky, and there is no sign of being "eaten" soon. In the early morning of July 22nd, I got up early, excitedly picked up the observation mirror and hurried downstairs. The red sun hung quietly for a long time, so I had to go back upstairs and watch live TV.
At about 8: 50, the sun on TV has lost most of its face, and the sky is getting dark. After a while, the black block became bigger and bigger, and the sun gradually became a thin line. When the moon is about to completely cover the sun, a shocking huge diamond ring appears in the sky! How beautiful! Because of the thick clouds, the sun's light ring looms on TV.
I ran to the balcony and looked up at the sun. I saw the diamond-like Bailey beads. Suddenly, there was an exclamation from downstairs: "Bailey beads are really beautiful!" " ""not the kui is a Bailey bead! I stood on tiptoe and looked downstairs. The community is crowded with people. Everyone looked up at the sky and looked forward to the second appearance of Bailey Zhu. Finally, in the long-awaited voice, Bailey Pearl appeared in the sky again, just like a beautiful woman just coming out of the bath, a hibiscus just coming out of the water. It's amazing!
Slowly, the sun showed less than half of its face and gradually returned to its original appearance. There are fewer people in the community, and everything has returned to its original state.
