I got a composition with excellent knowledge.

In our daily life, when it comes to composition, everyone is certainly familiar with it. According to different genres, composition can be divided into narrative, expository, practical and argumentative. In order to make your writing easier and more convenient, the following is an excellent composition (General 12) that I carefully arranged. Welcome to reading. I hope you will like it.

I got an excellent knowledge composition 1 One afternoon this summer, I was alone at home and happened to see a spider web in the corner of my yard with a struggling fly stuck on it. I thought: How on earth did spiders prey on this fly?

To solve this mystery, I began to stare at the flies. After a long time, I saw a spider crawling in the corner. I saw it quickly climb on the fly, spit out a milky silk from its mouth, wrapped the fly around it, and then slowly climbed back. I am puzzled: I want to know why this spider went back like this. Why not go back and eat flies? Is it not to his taste? In order to solve this puzzle, I continued to observe, but after waiting for a long time, the spider did not make any movement. I think the spider may have forgotten.

I always think about these problems at night. But the next morning, I was surprised to find that the spider had eaten the fly, leaving only the empty shell of a fly on the Internet. That's weird. How did the spider eat this fly? Why leave only an empty shell? I'm confused. In order to solve these mysteries in my heart, I thought of asking for help from the internet. Finally, the answer was found through the search for the mother: it turns out that spiders secrete mucus through the protrusions at the top of their silk sacs, which can condense into fine silk when exposed to the air. The web made of silk is very sticky, which is the main predation means of spiders. For insects that stick to the web, spiders will first inject their prey with a special liquid-jujube digestive enzyme. This digestive enzyme can make insects coma, twitch, die and liquefy their bodies. After liquefaction, spiders slowly suck away the liquid from insects, leaving only the shell of flies.

Through this observation and research, I finally understand the mystery of spider predation. Although this is only a small discovery, it makes me understand a truth: ordinary life is also full of knowledge. As long as you carefully observe and study, you can make new discoveries and gain some knowledge.

I have acquired excellent knowledge. Winter is coming, so it's time to eat Sugar-Coated Berry. The red Sugar-Coated Berry looks like a string of crystal agate, which is really appetizing!

Dad bought me a string, sour and sweet. I thought to myself, "Why can't our family make such delicious Sugar-Coated Berry?"

Turn on the TV at night, and the old Beijing candied haws are playing. I read it with relish.

The teacher began to talk: the first step is how to take out the hawthorn core. First cut a small hole in the top of the hawthorn with a knife, then cut a knife horizontally in the middle of the hawthorn, and you will see the hawthorn core, and then pick it out with a knife. The second step is to string the hawthorn in order from small to large, and then start boiling sugar water. The ratio of sugar to water is three to one. Oh, sugar and water are still proportional! It seems that there must be a certain way to do everything! When the sugar water bubbles, you can turn off the fire! Step 3: Turn the string of Sugar-Coated Berry in the sugar water three times and put it on the sprinkled chopping board, and the sweet and delicious Sugar-Coated Berry will be ready!

I begged my mother to go to the supermarket to buy hawthorn, and I couldn't wait to try it!

According to the teacher's practice, I took the hawthorn core first. Alas, the hawthorn is crisp. Too hard when picking up the core, it broke in half! By the third time, the core was completely taken out! It took me more than ten minutes to make ten pitted hawthorn! Then, I began to boil sugar water. I put twelve spoonfuls of sugar and four spoonfuls of water, and soon it bubbled loudly. The sweetness of golden sugar water is released into the air, which is really attractive! I strung hawthorn with a toothpick and put it in sugar water, as if the sugar water was a little less! I quickly rolled hawthorn in sugar water with chopsticks and put it on the chopping block to cool! After a while, I began to taste the spoils! Although it's not as good as what is sold outside, it's still from My Sweetie, because I've increased my knowledge!

I have acquired excellent knowledge. Time flies, and it's a new year, but this year I have a different New Year. I live in Shenzhen and I have learned a lot in this new year.

One day at noon, when we were having lunch, my aunt said, "Let's go to the movies in the afternoon." My brother and I were both happy and excited and said, "Yes, yes!" " Aunt said, "OK, I'll buy three tickets."

We have finished eating, so I'm going to sleep for a while. After a while, my aunt woke me up. I thought to myself: I don't want to leave the warm quilt. Forget it and get up. Aunt said, "Let's go to the movies." We changed our shoes and took the elevator downstairs. Aunt rode an electric car and we rode to the gate of the cinema. But look at the time. Let's go to the cinema upstairs. We bought movie tickets and entered the screening hall. Just in time, the film has just begun.

Suddenly, a policeman said some knowledge, such as: what to do if you meet a bad guy, if someone knocks at the door … After listening to this knowledge, I played a video like this on the screen. After watching these videos, we suddenly realized how to protect ourselves in the future.

The film was over and we filed out of the cinema. I was walking on my way home, thinking that I should memorize this knowledge so that I would know what to do when I met the bad guys.

I got excellent knowledge composition 4. One day in the summer vacation of the second day of junior high school, my children and I were playing by the lake in the community. When I was running, I accidentally kicked a lovely watermelon bug into the water. I quickly picked it up by the pond and looked at it.

I saw watermelon worms stretching their rolled-up bodies, crawling on rocks at the bottom of the water when they landed, as if thinking about how to surface again. I was curious, so I found a transparent glass bottle, caught a few bugs and put them in the bottle. I guess the worm will definitely drown, but all I see is the worm stretching its limbs comfortably and floating freely in the air like fallen leaves in the water. I quickly blocked the bottle mouth with my hand and opened a small crack to let the water flow out, leaving the bug in my hand. I put them on the ground and they slowly climbed back to the lawn. I was suddenly shocked and had nothing to say.

Through this small experiment, I know that this small watermelon worm can breathe freely and crawl freely in the water. By consulting the information on the computer, I know that watermelon worms have many small feet in their abdomen, and the longest foot is used by watermelon worms to breathe. Because of the evolution of watermelon worm, there is a protruding thing at the top of its breathing angle, which allows it to absorb oxygen in any environment and survive in water for a long time.

This discovery has benefited me a lot, and I have seen great knowledge that I usually don't pay much attention to. It makes me feel that knowledge can be seen everywhere in nature. Only by careful observation can we discover, master and understand knowledge and learn secrets that others have not discovered.

I got excellent knowledge composition 5 1 June1Sunday afternoon, my parents said they would take me to the Bird's Nest to watch an anniversary performance. I heard that there was a dragon and horse performance, and I was excited to say that I must go. The scenery there is as beautiful as heaven, the river is crystal clear, and the flowers and trees are full of vitality and variety, which is really dizzying.

When I arrived at the venue, the first thing I saw was a sea of people! But I can't see anything! Suddenly, I saw a small crack and I was about to rush forward. At this time, a kind aunt said, there are many children in front, so you should go. I'm very involved. First of all, I saw my favorite dragon horse standing by. I'm so happy that I want to make a hullabaloo about. At this time, unexpectedly, my father was willing to give me his mobile phone and let me take some photos. I jumped up with excitement and took some photos with my mobile phone. After a long time, today's dream performance finally began. First, I saw some fog disperse, then the sound was deafening and the dragon horse began to move. His neck is getting shorter and shorter. Then, the spider next to it shook, and eight long claws stretched forward for a while and then shrank back. Very interesting! But I paid special attention to the dragon horse, because his neck was more than one meter high, and I found that the car below was moving the machine.

While watching and listening to the explanation, I learned that the dragon horse is a dragon horse with a height of several meters and a weight of dozens of tons. The spider is about 5 meters high. 5 meters, 6 meters wide and weighing several tens of tons, the mechanical spider is equipped with about 15 operators, who are used to operate two behemoths, and each operator has about dozens of people in the whole performance team. The large-scale mechanical device of the dragon horse is taken from the China idiom, the spirit beast of the dragon horse. Longma used the elements of China culture and created it according to the interpretation of ancient legends in China. Such a large-scale performance is really not easy!

I not only feasted my eyes on the performance today, but also learned a lot about the history of China culture. I'm so glad you came!

I know composition 6 like the back of my hand. When school started, the teacher told us that the exam was coming. I was so excited to hear the news that I decided to get a good grade.

When I come home from school, the first thing I do is to review the materials. I read Chinese, math, English and the knowledge points that the teacher said before, and then memorized them. I copy the questions that I can't and are easy to make mistakes in my notebook and practice them again and again. If you don't understand, ask your mother and let her explain it to me. Until you understand and do it. Keep reading extracurricular books every day, read them once every time, mark favorite idioms and sentences for the second time, and accumulate beautiful words. Now I have read many books, including PHS roaming, fables, Andersen's fairy tales and insects. ...

It's finally time for the exam. Get ready for school supplies and get to school early. I'll check my school supplies again and adjust my normal state of mind. The teacher handed out the test paper, checked it first, wrote down the name and student number, and then began to do the easy ones first, and then the difficult ones. If you don't have it, you will leave it for the last time to read the questions again and again, and then do it when you think about it. Finally, complete the whole test paper and check the first question. Finally, the bell rang and I handed the test paper to the teacher with confidence!

A few days later. My grades have come out and all three subjects have reached my expected scores. It's not the best, but it's much better than my last exam. My teacher and mother praised me, and I smiled happily. Mom said don't be proud! Make persistent efforts, we will not be disappointed in the end, and strive for better results next time!

I have acquired excellent knowledge. I studied from kindergarten to grade three for six years and learned a lot.

When I was in kindergarten, I learned numbers from one to ten and simply recited ancient poems.

In the first grade, I learned to add and subtract one to forty dollars in mathematics, and I used the addition and subtraction of one to forty dollars to solve problems. In terms of Chinese, we learned ancient poems that are difficult to recite, as well as pinyin and simple words. What we learn most is that I can write. "Writing" sounds simple, but it is really difficult to write well. In the second grade, I learned multiplication and division in mathematics. The teacher also asked us to memorize the multiplication formula before we could do the problem. I won't do it if I can't recite it. In terms of language, we memorize the accumulated ancient poems and add poems.

What I learned in grade three is a hundred times more difficult than that in grade one, so the knowledge in grade three is even more difficult, and there is also an English language. In the third grade, I learned decimal points, fractions, two digits and recited ancient Chinese. It is especially difficult to recite words in English. I also know that China has a lot of knowledge ... to learn.

"Knowledge quantity" sounds simple, but it takes a lifetime to finish learning. The ancients once left a sentence, "It is never too old to learn". Knowledge can never be learned. I am still young, and I find it difficult to learn knowledge in grade three. In the future, I will study hard and study the knowledge left by our predecessors in China.

I have acquired excellent knowledge. That day, I saw a little experiment in a science book-water sprite. I'm curious. Are there elves in the water? So, I will do this little experiment to verify whether there are elves in the water.

The materials to be prepared are colored pigments, vials, mineral water bottles and water.

First, fill the mineral water bottle with water and spill it. Then, pour the pigment into the bottle to make the water look more beautiful, and then put the vial into the water. Finally, we just need to observe carefully. After a few minutes, the pigment slowly melts, and the color of the bottom of the bottle is the deepest, which slowly spreads to the height of the bottle, and finally the color is the same from top to bottom. This process looks really wonderful. After a while, the 1 bottle actually floated up from the bottom of the water. In a short time, small bottles floated from the bottom to the top of the mineral water bottle one by one. I continued to observe, and after a few minutes, the little bottle slowly sank to the bottom of the water, as if the elf were asleep at the bottom. I continued to observe, and after a while, the small bottle rose to the top of the mineral water bottle again. Ah! It's amazing.

Through this experiment, I come to the conclusion that the bottle can float on the water because it can float on the water through the reverse thrust of water. The greater the reverse thrust, the faster the bottle rises. A small experiment made me understand so much. Life is really full of knowledge!

I have acquired excellent knowledge. I have gained a lot of knowledge this semester, and I am very happy in my study!

Under the teacher's careful education, I learned the position and direction of mathematics, double statistics, double digits multiplied by double digits, area, and so on. I also learned many new words, beautiful sentences, ancient poems, how to write notices, fables and stories, profound traditional culture, how paper was invented, majestic Zhao Zhouqiao and so on.

I also like reading extracurricular books, such as why chameleons can change color? Do you know that?/You know what? Let me tell you something! A chameleon changes its body color to protect its skin. There are many pigment cells in its skin, so it can change color. What is the use of our tears? Can make moist eyes elastic, and has the function of detoxification, and can also wash away the dust on the eyes! There is still a lot of interesting knowledge in extracurricular books, so read more books when you have time!

In this way, I have gained a lot of knowledge. I will study hard and get more knowledge in the future.

I got the excellent knowledge composition 10. It was a sunny day, and my mother took me to the park to play. The flowers in the park are really beautiful, each with its own shape and color. Look at that and this.

These flowers are really beautiful, including peach blossom, winter jasmine and golden rape. There are some flowers that I can't say or see. I asked my mother: what flower is that? He looks really beautiful. My mother listened to my words, looked at the flowers and answered me: the flowers are apricots, smelling faint fragrance, which will bear apricots! I listened to my mother and nodded.

Then walking, I found some flowers that I didn't know. I asked my mother, What is that flower, mom? How beautiful she is! My mother listened to my words, looked at the flower I said and answered me: that flower is a pear. It blooms in March and will bear pears then. I listened to my mother's words and thought: I also want to know pears and apricots! Mom seems to have read my mind and said, when the pears and apricots are ripe, I will take you to the country to eat the freshest pears and apricots!

I jumped for joy after listening to my mother's words! But the reason why I jumped up was not because I could eat fresh pears and apricots, but because I learned another kind of knowledge today, that is, the knowledge of flowers. I am very happy!

I got the excellent composition of knowledge 1 1 I grow up happily on campus and study with my classmates every day. In class, we scrambled to answer the teacher's questions and increased our knowledge. I grew up tirelessly. In family life, I occasionally help my mother do housework and cook some simple food. My parents love us, and we grow up carefree.

The joy of growing up is in giving, helping her get moved and happy. In my life, teachers and mothers often teach us to respect the old and love the young, help those in need and do what we can. For example, when I see paper or other rubbish on the ground at school, I will pick it up and throw it into the trash can. Every time I cross the street, I will help the elderly with mobility difficulties to cross the street.

During my three years in school, I gained a lot of knowledge, made many friends and learned a lot of truth. Every time I grow up, I gain something, strength, courage, self-reliance, understanding and diligence.

The process of growing up is hard, but we have gained a lot. Life has taught us a lot and we still have a long way to go. There are still many things we need to experience, maybe laughter, maybe failure, maybe wind and rain.

Growing all the way, harvesting all the way, I grew and harvested.

I got the excellent composition of knowledge 12. People say, "Books are the key to the ocean of knowledge." Today, I will tell you my knowledge.

Knowledge 1: Mathematics

In the wonderful world of mathematics, I know wonderful Arabic numerals and grotesque figures ... I have read Li Yupei's mathematical fairy tale "Wonderful 9" and other books. I study in the sea of books. In that vivid and interesting picture, I seem to see the little tiger who doesn't like arithmetic, and with the help of the pencil necked, he likes arithmetic. 9 can not only add, subtract, multiply and divide, but also crack remainder, cyclic decimal and geometric triangle. Therefore, I gained a lot of mathematics knowledge.

Knowledge 2: Chinese

In the interesting language paradise, I met many famous people: I became attached to Lu Xun in the white grassland, passed Xiao Hong in the quiet street, watched the statue of Little Orange Lamp with Bing Xin in Geleshan Cultural Square, watched my father's back with Zhu Ziqing, wept together, and was appreciated by nursing students with Feng Zikai ... I found that vivid Chinese characters were the controller of our emotions, and I gained something.

Knowledge 3: English

In the magical English world, I know a wonderful language like Chinese-English. Here, I studied hard and studied hard, and finally won the championship in last year's English Song Grand Prix.

I learned a lot of knowledge!
