Excellent composition 1 "do the first question on page 39." Under the teacher's order, our class picked up a pen to write questions.
The teacher said, "these questions should be approved by each other at the same table." If you make a mistake, write it down first. Now you have 20 minutes to do it. " I thought to myself: What if I make a mistake? Twenty questions, with an average of only one minute for each question. These questions are all division, except for law, I am the worst. As soon as I saw that all these questions were finished, I turned to thinking, "I should be able to finish them within the specified time." I successfully completed the first few questions. I made a mistake at 4x8x 125. Why does a multiplication problem pop up suddenly? This question is too difficult. What should I do? Don't do it if you can't. Talk to my deskmate and ask him not to give me a wrong judgment. I was just about to tell him, when I suddenly remembered my mother saying, "Nothing is difficult in the world, if you put your mind to it, you can't do it in the end." I feel confident when I think of this sentence. I have finished all the questions in the meeting, and this is the only question left. I thought to myself: I can definitely figure it out after I finish the calculation, so I picked up the calculation paper and began to calculate it over and over again. In the end, everything paid off. I finally solved it. 8x 125 equals 1000. Is it wrong to multiply the number of uses by 4? The teacher said, "Mark the papers." After the students finished evaluating the questions, the teacher said, "Please raise your hand if you make a mistake." I held my breath, ah! My deskmate didn't raise her hand, so I thought, how hard it is!
It is said that difficulties are like springs. If you are weak, it is strong, and if you are strong, it is weak. In the face of difficulties, all difficulties can be solved as long as you have confidence.
Recently, the sewer at home has been blocked by something, and the sink can only receive water, not drain it. Every day, when mom and dad finish washing vegetables and cooking, they always accumulate a big pool of water and scoop it out at night, which is laborious and time-consuming, but what can we do? Dad poked the sewer several times, but it didn't help. Finally, he had to bite the bullet and scoop water.
That night, my mother walked impatiently to the pool again. As soon as she picked up the ladle, her eyes suddenly lit up and she said happily, "Let's use siphon phenomenon to drain the water in the pool and put it in a big basin, so that we can clean it without bending over, saving time and effort, and finally we won't get it!" Dad patted his thigh and said, "Yes, that's a good idea!" " "My sister also said happily," Mom is still witty! " But I was shocked. What is the "siphon phenomenon"? How can I suck the water out of the pool? This series of question marks makes me confused. Soon, my mother brought a thick plastic pipe, filled it with water, put one end into the pool, the other end hung in the air, and there was a basin behind it. After a while, the water was sprayed into the basin and it was all sucked up in just half a minute. This is much more convenient than scooping it out, but what is the principle? So I asked my father, who smiled and said, "Siphon phenomenon" is a term in physics. When the plastic pipe is filled with water, there is no air in it. Put one end of the pipe into the water and the other end hangs down, and the atmospheric pressure will press on the water surface in the pool. The pressure outside is greater than the pressure inside the pipeline, so water has nowhere to go but into the pipeline. In this way, the water is pumped out. Moreover, the other end of the pipe must not be higher than the end that extends into the water, because the water always flows from high to low. Hearing this, I seem to understand.
Mom's solution to the problem is not only clever, but also like giving us a small scientific experiment!
When the lost spirit falls from top to bottom like a waterfall, I stand on the branch of history and look back, trying to find the answer to the question in various books.
Every problem has its own answer. Just like a math problem, no matter how difficult it is, it can be worked out. There is only one answer, but there are many algorithms. As long as you don't give up, you can work out the answer. So no matter what difficulties you encounter, as long as you persist, you will certainly find your own answers and find a variety of solutions!
It is an important obstacle to solving difficult problems when you are confused, and it is also an important obstacle. Can't this obstacle be broken through? I remember a few words: "Nothing is difficult in the world, I'm afraid there is a will." If you want to overcome difficulties, you must persevere, constantly strive to change and overcome difficulties! Some people may have such a question: "Who will tell me how to solve the problems of this era and who will save our lost spirit?"
This robbery is also for a plan.
It is ourselves who can solve this difficult problem. Just like Mr. Lu Xun said, be a spiritual fighter, so as to fight against vanity and despair in the dark. We should stand under the starry sky, look up at the moral law overhead, accept the correct instructions in the moonlight, find the internal basis and persistence, and find the lost spirit. And all this is the answer to the question.
We need to awaken those sleeping souls with new anger. To be a problem solver of an era, give birth to the hope of transcending falsehood from falsehood and hand over the most perfect answer sheet for this era.
Don't be stumped by difficult problems. Believe in yourself and believe that you can do it! Come on!
On Saturday, after breakfast, we began to struggle. Do your homework at eight o'clock! After doing it for a while, I stopped doing it. It turns out-I was stumped by a math problem that found regularity!
The topic is as follows: 3. 125,,, 12.5,,, 100. Seeing this question, I was blindsided at once and thought: what is this topic? Without rules, how can it be called "filling in the blanks according to the rules"? I was speechless, so I had to draw an "∞" on the subtitle of the topic to indicate no. Sighed and continued to struggle.
After I finished all my homework (except the weekly diary), I continued to study this topic. I was thinking, and it suddenly occurred to me: could this problem be the difference problem mentioned by teacher Zhang in grade four? Curious, I took out my computer, pressed "12.5÷3. 125=" and jumped out of "4". I suddenly felt a great increase in hope. Keep exploring. Press "100÷ 12.5=" and jump out "8". Great, I did the right thing!
4÷2=2,3. 125×2=6.25. In this case, the first horizontal line should be filled with "6.25". 6.25×2= 12.5, right, right! 12.5×2=25, according to the previous statement, then the second horizontal line should be filled with "25"! 25×2=50, there is no doubt that it says "50" here. 50×2= 100, yeah!
Haha, I found the root of the problem-think about it!
Seeing this topic, you may wonder why it is a "simple question". Don't worry, listen to me slowly.
There is a question on the recent math test paper: turn a circle into an approximate rectangle. It is known that the circumference of a rectangle is 5 cm more than that of a circle. Please draw this circle. This question stumped me. I've been thinking hard for a long time, but I just can't figure it out. I decided to ask my grandfather, "Grandpa, how do you think this problem is done?" Grandpa took the test paper, picked up a pen and paper, and did it after reading the questions.
time goes by ...
Grandpa said, "I can't draw. You see, this problem has neither a rectangular perimeter nor a circular perimeter, so it can't be drawn. You'd better go to school tomorrow and ask your classmates! " I took the test paper and went back to my room in disappointment.
The next morning, I got up at four o'clock, just as grandpa got up. I turned on the desk lamp, took out the test paper and thought with grandpa. The conversation between us woke up grandma, and grandma joined our discussion. It's five o'clock, and I haven't decided what to do yet. When the problem just started to make some progress, my brother's crying completely interrupted grandpa's train of thought. ...
When I got to school, I hurried to ask other students in our group to talk about it. It suddenly dawned on me that the extra 5 cm is the diameter of the circle, and we can draw a circle, as simple as that! It's too complicated for me to figure out. This question is really a well-deserved "simple question"!
Question Excellent Composition 6 Everyone will encounter problems from childhood to adulthood. My problem is-doodling. My mother always tells me that in order to overcome difficulties, I must face them bravely.
On this day, the teacher announced an important thing in class, that is, practicing calligraphy every day. I suddenly felt a knife stab into my heart, and I couldn't help thinking: God, please help me! Writing is more painful to me than death. What should I do? ...
When I got home, I took out the "good words" arranged by the teacher and felt that the whole person was going to be broken. However, I can't help it. I am a student who is not used to handing in homework, so I have to take out a heavy pen from my schoolbag, open the first page and start painting it red. It's written, and I seem to think of something: the teacher's request is to have a look, two looks and three welcomes. I didn't seem to make one, so I just jumped to two. And when tracing red, it should be full and not overflow, and write one after tracing. No, I have to do what the teacher says, and I don't want to rewrite it. The past fifteen minutes, twenty minutes ... have finally been completed.
I can't help saying, "I am a genius, and my handwriting is beautiful!" " "
The next day, when I handed the "excellent handwriting" to the group leader, an idea popped up in my mind: I can write so beautifully for the first time, I will definitely get an "excellent" and then take it out as a standard word. "Ha ha ha ha ..." I smiled happily.
As I expected, the teacher gave my homework an "excellent" and asked my classmates to learn from me.
From then on, I fell in love with practicing calligraphy.
In my five years of primary school study, I have encountered many problems: inattention in class and small gestures, but the most unforgettable problem is that English is not standard.
I remember when I was in the third grade of primary school, I just started taking English classes. At first, I was very excited, and my heart was pounding like a deer, waiting for the arrival of English class.
However, when the teacher introduced himself and started the class, I realized that it was not like that at all. When the teacher taught us to read the word "apple", all the other students read it fluently. Only when it was my turn, I blushed and stammered "Oh dear", which made my classmates laugh and the teacher stamped her feet with anger. In the English exam, because I didn't know anything in class, I was honored to be marked with a "red lantern" by the teacher on the test paper. To this end, my English team leader is like an angry buffalo, bubbling in his nostrils, sucking a large basin of water from the river and spraying "water" (saliva) on my face; I am like a mouse about to be caught by a cat, and I can't wait to get into the ground. At this time, I am angry and helpless!
In order not to be angry with my teachers and classmates, I made up my mind to "put down the butcher knife and become a Buddha." Since then, I have spent a lot of time practicing English every day, but it is useless, even far from the standard pronunciation. But I still don't give up. I often go online to search or ask my parents, teachers and classmates. Finally, many things have happened, and my English has finally improved. This makes me understand: no matter how difficult it is to do something, as long as you persist and persevere, you will succeed.
Some people say, "The problem is not terrible. The terrible thing is that you don't have the confidence and determination to overcome it. " Looking back on an incident that happened a few years ago, I think this sentence is really reasonable.
As the final exam approaches, our homework is getting bigger and bigger every day. There are many papers to do every day, which can be described as mountains! I do my homework until nine or ten o'clock every night, and my handwriting gets worse. Dad can't help me when he sees me in this situation, because there is too much homework. In addition to a whole day of cram school on weekends, I have to do a whole day of homework. My father will take me out to exercise my bones and muscles. So I had an idea: improve, improve, improve the speed of homework! And do as much homework as possible after class to ensure the rest time at home.
The next day, I began to take action. A week later, my writing speed improved quickly, doubled. I am so happy that I am determined to finish my homework before eight o'clock! Many things happen. Two weeks later, I really finished all my homework before 8 pm. I jumped three feet for joy. After that, my homework can be finished before eight o'clock.
By doing my homework, I overcame the problem of slow writing, and I finally succeeded!
I am a person who likes the new and hates the old, but because of this, it has brought a lot of troubles to my life.
Once, when I saw my father bring back a lot of food from the company, I couldn't help being tempted. I found a good opportunity and stole some. Ah, it's delicious! I can't help admiring in my mind. A few days later, I saw my father bring back some food, so I ate more. As a result, for the first time, I stopped thinking about the food my father brought back. After a few days, my mother cleaned up and found something to eat, but it was overdue and could not be eaten.
Another time, I saw a lot of beautiful little books sold in the shop, so I asked my mother to buy me one. A few days later, I saw a new style of book in the shop, which was better than before. I asked my mother to buy me another one. A few days later, I found a more beautiful book in the shop, so I asked my mother to buy me another one ... wait, my book. I listened and said nothing, but bowed my head in shame.
Students, can you help me find a way to solve this problem?
10 winter vacation, the teacher assigned an assignment-making lanterns by myself. A few days before school started, my mother and I started making lanterns.
First of all, I have to prepare the materials for making lanterns, just when I am at a loss. I saw the cake my mother bought at noon. Its box is a pink cube. I thought to myself: Isn't this the ready-made material for making lanterns? But the gap in the box is too big. So I stuck the gap in the cake box with double-sided tape and sealed the opening. This box is square. I felt very rigid, so I cut a lot of orange love on the cardboard with scissors and stuck it on all sides, and cut small yellow and purple butterflies and stuck them on both sides of the cake box as decoration. Because the butterfly I posted is three-dimensional, it looks lifelike and particularly beautiful, and I also made a lantern model.
Then the lantern needs a stick to carry. But where can I find this stick? Suddenly I had a brainwave and remembered the bamboo poles in my garden. So, I chose a bamboo pole with moderate length and uniform thickness. In order to make this stick more beautiful, I took out the lesbian ball, cut off the ribbon on it, wrapped it around the bamboo pole one by one, and tied the bamboo pole to the cake box with a rope.
Finally, in order to make the lantern more beautiful, I cut dozens of ribbons and tied them into a string of tassels, and then sewed them on the bottom of the lantern with needle and thread. In this way, after some non-stop busy, a complete lantern appeared in front of me.
Although I encountered many difficulties in the process of making lanterns, I solved them all. Through the experience of making this lantern, I understand a truth, nothing is difficult in the world, nothing is impossible to a willing mind. Don't be afraid when you encounter difficulties, think first, and don't ask others for help when you encounter difficulties.
Excellent composition 1 1 Late at night, I was still reading night books and unconsciously cut my nails. The door creaked open and mother came in. Listening to the "click" sound of nail cutting, she glared and reached out to hit me. We had a fight. Then I knew that a high wall was erected between us, and there was a password on the wall, which was a problem I couldn't solve.
At noon the next day, I went home reluctantly. The wind was so strong that six or seven grains of sand got into my eyes along the way. How boring. I didn't knock on the door angrily, but I was greeted by a long-lost chill and delicious food. I quickly adjusted my expression and looked into my mother's eyes. Her eyes are as soft as usual, and I seem to be very uncomfortable. He walked quickly to the table and raised his chopsticks. Eat delicious food as usual. My mother always said, "The happiest thing for a chef is that the people who eat it say that her cooking is delicious." But I just said it in my heart and couldn't say it. I know, my mother has entered the password half right. That half is my problem.
While my mother was not at home, I looked at the messy home-all kinds of charging cables were jumbled together, snack bags on the coffee table were scattered all over the floor, and the backrest on the sofa was uneven. My mood became extremely boring again. I can think of my mother's kind eyes and delicious food. I made up my mind to give her a clear perspective when she came back. I bent down and worked hard, shuttling between rooms, and I was sweating before I knew it. At this time, my waist can't stand up straight. Stiff neck, unable to move. But I know that I have solved this problem. It only takes a single blow to completely knock down that high wall.
The problem is difficult only because we didn't take the initiative to solve it. As long as we take the initiative, the problem will be solved naturally.
12 Mathematics is a wonderful subject. Although it is complicated, it combines numbers and numbers perfectly, which makes people intoxicated. The problem is the gymnastics of our thinking, the boat that allows us to reach the other side of success.
In today's math class, the teacher explained to us the thinking questions on page 28 of the math book. At first glance, this problem is a bit confusing to monks, but after deep thinking, grasping the details and finding the breakthrough point, the idea of solving the problem will be presented. We know the radius of the bottom surface of the round steel, and then write down that when the round steel is pulled out of the water surface by 8cm, the water surface will drop by 4cm. Then we can immediately think that the pulled-out volume is equal to the falling volume of the water surface, and then we can find out the falling volume of the water surface divided by the height of 4cm, and then we can find out the bottom area of the pool. As mentioned above, the water level rises by 9cm after the round steel is put in, so the rising volume is the volume of the round steel, which can be solved by multiplying the bottom area by 9. All the students can answer this question, and the teacher is very happy. But some students have other methods. A classmate thinks that in this problem, the water level will drop by 1 cm every time the round steel is pulled out by 2 cm. I summed up his words mathematically: the moving distance of round steel: the moving distance of water surface = 2: 1. Then the water level rises by 9cm, which means that the cylinder drops by 18cm, and the height is 18cm. Then the volume of round steel can be directly calculated by multiplying the bottom area by the height. After listening to our answers, the teacher said that we were very good.
Although the difficult problems in mathematics are difficult, as long as we can solve them with what we have learned, we will find that mathematics is endless.
The novel Father's Problem (13) is a thought-provoking chapter, which tells us that Paul and his father have different views on the reasons why the tortoise won the race between the tortoise and the hare. My nephew learns from his father-loyalty and tenacity are the magic weapons to win.
It is true that the congenital deficiency of birds and turtles exists objectively, and the victory of turtles has a lot to do with rabbits sleeping in the middle. However, if the tortoise does not climb forward step by step with general resilience, then the rabbit will not win the crown of victory no matter how long it sleeps. It can be seen that it is impossible to win without the spirit and resilience of birds and turtles.
In fact, there are also many people who are "congenitally deficient" and succeed on the stage of life by virtue of their strength and resilience. Deng Yaping, an athlete who won two gold medals at the Barcelona Olympic Games, won numerous honors. Who would believe that this is the record of a very small person-only 1.50! Compared with those excellent European moxibustion players, although her boat condition is much worse, she is solid and resilient. She falls tens of thousands of times before the stage every day, and her feet are still crawling with sand. After the recording, she finally learned how to smash with one hand as fast as lightning, playing all over the audience and winning glory for the motherland.
We are in an era of competition, and if we are not careful, the manuscript will be eliminated, especially those who are "congenitally deficient". We should carry forward the spirit of the tortoise, study, work and create a bright future with Lingling, and win one victory after another.
Everyone has encountered the problem of excellent composition 14. For example, there is something wrong with math, and you can't write a composition, and so on. The question I want to talk about today is very different, because it is a moral issue.
It happened after school yesterday. It's getting dark, it's raining hard, and there is water everywhere, as if God is angry. As the bell rang, I walked out of the school gate with my classmates. Because we need to buy some materials for the science class, we went to the stationery store next door to buy materials. Out of the store, I suddenly saw a five-dollar bill on the ground that was not soaked by rain. I picked it up and took a closer look. It's really five dollars. I think: should I buy a lollipop alone, or ask people around me if they have lost money? I'm in a moral dilemma. After some ideological struggle, I still think we should ask people around us if they have lost money. I was just about to start asking when the aunt of the stationery store came out and said, "This five dollars was lost when the old uncle who walked in front paid. I just left and should be able to catch up. " Finally, menstruation said, "You must run and catch up!"
After listening to my aunt's words, my classmates and I immediately ran forward. Finally, we saw two old uncles in the service corridor. I walked up to one of them and asked him if the five yuan was really lost. I returned the five dollars in my hand to him, said goodbye and went home.
After returning home, although my clothes are wet, I feel extremely happy, because with honesty, I have a lot of wealth. Also because honesty is a passport to life, honesty has won me the competition advocated here.
