difficult problem

In ancient times, if someone asked, "Is the earth round or square?" What a difficult problem it was for people at that time! Now, a kindergarten child can easily answer loudly: "The earth is round!" " "

In ancient times, people could not sail. There are no satellites, rockets and spaceships, so they can't find the position and shape of the earth. However, with the passage of time, people from generation to generation constantly put forward all kinds of difficult problems, and constantly seek and explore answers in life practice. Over time, today's knowledge wealth and human civilization have been formed.

I remember when I was a sophomore, I was confused by a math problem: 1 1 There are 30 days. If 1 1 has five Saturdays and Sundays, what day is 1 1? What a difficult question this is!

This question is very simple for me now. Because I'm growing, I'm making progress, I'm thinking about difficult problems from simple to complex, and I'm trying to find answers. Old problems have been solved, and new problems are in front of us.

Whether it is a person, a social group, a country or even the whole mankind, there will always be various problems with us in the long river of time. Suppose that people from ancient times to the present are lazy and proud. Always choose to escape and retreat when encountering problems, and can't think of new problems. What kind of world will it be today? Our existing human civilization will no longer exist, and we will still be apes clinging to the dense branches and leaves of the virgin forest to pick wild fruits for food.

Why do ships and planes entering the Devil's Triangle in the United States and the Dragon Triangle in Japan disappear? This is a mystery; The mysterious crop circles are another mystery. The earth and the whole universe are full of many mysteries. In today's world, we still face many problems, such as environment, diseases, natural disasters, wars and so on. These are all waiting for us to solve now and find the answer.

In short, in life, study and work, when we encounter various problems, what kind of mentality should we face? Is it to escape retreat, or to advance despite difficulties, be brave in making progress, and make unremitting efforts for the ideal. Different choices will lead to different results. We humans are the smartest creatures in the universe. How should I choose? In fact, our ancestors have already told us the answer.

difficult problem

At the beginning of life, time left many problems for life. Different people have different solutions-some people avoid it, some people look at the ocean and sigh, and some people complain that heaven is unfair. Why are there so many problems? Some people think hard and don't know how many brain cells died, but they hanged themselves from a tree after all. Others change their thinking angle and solve problems flexibly, in exchange for the epiphany and pride of "a bright future".

Take me for example, once upon a time, I wanted to be reincarnated in a foreign country, so that I didn't have to climb the steep peaks piled up by the problem sets-sometimes when you stumble to the top of the mountain and want to laugh three times, you are pushed into the abyss by the overwhelming test papers. In this way, I always look at the relaxed smiles of foreign students, so I always leave a wry smile of fantasy, so I always feel a heavy burden on my shoulders. What should I do in the face of such congenital problems? After all, I can't become a little foreigner, I can only accept the fact. But it's always a pity to accept the truth, so what I have to do now is to make a sharp turn. I can think of it this way: it's hard to get up in the morning and I won't come back in my prime. Although foreign students are relaxed, they let the autumn moon and spring breeze pass by inadvertently, and at that time, they lose their minds and feel sad. But I can spend their coffee time studying, isn't it worth it? Thinking like this, I seem to see this life problem with my tail between my legs, running away to find trouble with others.

Besides, I was born in a family that is neither poor nor rich, and some people may regret it, but I want to say that wealth is not dispensable, and the rich and the poor have their own advantages-the children of the poor family have a gray childhood; Although the children of rich families have everything, they are easy to be arrogant and extravagant, and their willpower is not fully exercised. Look at me standing between the rich and the poor. Who says I'm not the happiest? It's easy to let it go when you think about it from another angle.

There are many such inherent problems, such as appearance problems, gender problems and so on, but as long as we think from a different angle and in a different way, all problems can't be called problems.

There are still some problems that are rocks in the waves of life and waves in the long river of life. We can still look at them in a different way-we can learn from them if we fail the exam; A fall is lucky because there is no fracture; There is no need to grieve over the theft of our home, so we should donate voluntarily ... in this way, our eyes will be as high as the sky and our hearts will be as wide as the sea.

People who look at life from another angle must know the truth that "a blessing in disguise is a blessing in disguise"; People who look at life from another angle will not fall into the quagmire of suffering and losing.

2. Skilled writing, 280 words to solve problems.

Little monkey Cong Cong is a clever, lively and intelligent monkey. He especially likes to play around.

On this day, Cong Cong, the little monkey, came to a castle and saw many people sitting on the lawn in front of the city wall and drawing something. He couldn't help being curious. He walked up to a young man and saw that his paper was full of triangles. He asked, "What are you doing?" The young man said impatiently, "Go, go and leave me alone." After asking several people, the result was the same. Finally, a kind old woman said to him, "Go to the city gate and look at the placard on the wall." Cong Cong came to the city gate, where there were many people. He found a gap and got in. He looked up, and there was a poster on the wall, which read: There is a problem to be solved today, and whoever can solve this problem will be rewarded with 100; If you can't solve the problem by displaying the list, re-enter 40 boards. This list is specially released. Next to the post is that topic, which requires cutting an isosceles triangle to get a rectangle.

The little monkey's brain turned quickly and drew a few strokes on his palm. He couldn't help but shine at the moment, patted his head, stepped forward and unveiled the placard. "Someone revealed the list, someone revealed the list!" People rushed to tell each other that the soldier who kept the order rushed forward and held Congcong tightly, fearing that he would escape.

Cong Cong was taken into the palace by soldiers, and those onlookers followed him into the palace. They want to see how this humble little man solves their confused problems. The king sat high on the throne. He looked at the ugly poster and said loudly, "You can do this problem. Do you know the consequences of not doing it? " You don't want to suffer for this 100 gold! "Congcong said quietly," how can I make fun of my * * *? Of course I'm ready! The king was surprised and said, "Then tell me how you solved this problem?" Cong Cong said, "Please give me a big piece of paper and a pen. Cong Cong drew two big isosceles triangles on the paper, and then said, "There are two solutions to this problem. The first one is to find two midpoints on the waist of a triangle, make the midpoints perpendicular to the bottom, then cut along the vertical line, and rotate the cut part counterclockwise and clockwise around the two midpoints respectively 180? It forms a rectangle, just like the first picture. " Cong Cong said while drawing on paper, "The second solution is to find the midpoint of the waist, and then connect the two midpoints, and then cut the vertical line and vertex of the connection line, and cut them along the connection line and vertical line respectively, and rotate the two small triangles counterclockwise and clockwise around the two midpoints respectively 180? It forms a rectangle, as shown in the second picture. " The king and the onlookers were dumbfounded, and it took a while to return to god and clap their hands. The king smiled and said, "Yes, yes, someone, bring up the reward. Hearing this, Cong Cong took the money and pushed the crowd away. "。

Congcong exchanged gold for a lot of broken silver, leaving a little money for the trip and giving the rest to the poor in the city.

3. Write a composition on the topic of "Question". How to write? What would the world be like if there were no problems for human beings?

The problem is something that needs to be solved. Our study and work is to study, understand and finally solve problems. Whether the problem can be solved satisfactorily depends on both the problem itself and our ability, level, art and methods.

Problems are big and small, subjective and objective. There are contradictions and conflicts between countries, such as right and wrong, as well as brief quarrels and disputes between parents, such as details of life; There are objective problems such as earthquakes, volcanoes, storms and electricity, as well as insignificant subjective problems such as cowardice, doubt, disappointment and resentment.

No matter what the problem is, first of all, we should face it squarely, don't exaggerate it, don't shrink it, and grasp its essence in order to prescribe the right medicine. After mastering the essence of the problem, we must find the correct solution. It is necessary to talk openly, judge elegant words, listen to them clearly, combine the advantages of various methods and use them flexibly.

It takes great perseverance to solve problems. Not afraid of setbacks, not afraid of failure, twists and turns are often the beginning of success.

The process of social development is the process of constantly solving old problems and constantly generating new ones. Only by constantly improving their ability and methods to solve problems can we achieve our goals in life and glow with a wonderful life.

4. How to write the composition "Solving problems with your brain" in the third grade to solve the crisis? One day in the sixth grade winter vacation, my grandfather and I went to play. Grandpa's house is very interesting! I have everything I like, such as trees, dragonflies, rivers and so on.

And my favorite place is the grove next to grandpa's house! I go there to play almost every day, but it also brings me a little trouble. It was an afternoon, and I couldn't bear loneliness. I told grandpa, and then I went to play in the Woods. When I got to the Woods, I saw the trees were tall and dense, so I wanted to go up and play. I rubbed my hands, clasped the trunk with both hands, and climbed up step by step with my feet on the trunk. Soon, I climbed the tree. Looking at the distance, I shouted like Mount Tai and jumped up and down on the branches. It can be said that it comes and goes freely. But at this time, I accidentally stepped on it and fell from the tree. I shouted, "Help!"

Help! "Fortunately, there was a close call. I landed at the intersection of two tree trunks and got stuck. I thought: this is terrible. I fell into this ghost place. I can't get up or down. I struggled to break free, so I propped up the trunk on the left with one hand and the trunk on the right with the other, and then worked hard together. Just as I was about to break free, the thin trunk on the right broke. I fell at once. After all, I am very alert. My right hand immediately took it back. Grab the trunk on the left with both hands. But how can this twig bear my weight of 40 kilograms? The small trunk is slowly tearing. I used my quick wits and finally came up with a helpless way-I had to do it as the branches fell to the ground because I couldn't think of a way. I let * * * land first, because then my injury will be lighter. At this time, the trunk was broken, and I closed my eyes and waited for the arrival of bad luck. But at this moment, it seems that there are gods helping me. I opened my eyes, and when this small trunk approached the trunk, I opened my hands and jumped forward. I hugged the trunk, and I slipped down from it slowly and smoothly. I am very happy, because I solved a "crisis" myself, and I ran home happily. Through this, I will learn a lesson. I solved a small "crisis" myself, which was really good.

5. How to write a composition "Solve a puzzle" Although the ancients said that "nothing is difficult in the world, but there is a problem that has been bothering me since I was three or four years old. Alas, why is it so difficult?

Three or four years old: my brother grabbed me and said, "If you answer the following questions correctly, I'll treat you to candy!"! There are five birds in the tree. The hunter killed one with a gun. How many are left? " "4." I answered without thinking. My brother said angrily, "No! With a bang, didn't all the birds scare away? "

Five-year-old: When I was in kindergarten, my aunt asked me in a sweet voice, "Shoot birds in the tree." I rushed to answer, "No!" My aunt praised me for being happy, but it seems to be cold in the future.

Entrance Examination: Oh, my God! What a world this is! Let me win "Shooting Birds in the Tree" again. This time, I answered slowly: "maybe not, because of the gunshot;" There may be four, because it is a fake bird or a' silencer gun'; There may be, because birds are too stupid and have problems with their ears. . Aunt immediately announced that I had passed the exam.

Ten years old: During the Chinese New Year, my mother took me to play. I watched Shooting Birds in the Tree. Without thinking, I replied, "No, because the birds were scared away by the gunshots." I was boasting proudly about getting a gift, but my aunt said, "The correct answer is no bird hunting." I retorted, "No, there are many possibilities!" Aunt said impatiently, "Don't be paranoid! The correct answer is only' no bird hunting'! "

Twelve years old: My mother suddenly came into my room and asked me about "not shooting birds". I replied, "No bird hunting!" Unexpectedly, my mother said, "It's gone! Or ... "Then say a lot of possibilities.

Alas! This question is too difficult! There are five birds in the tree. The hunter killed one with a gun. How much is left? I don't know. Guess what, it's really puzzling!

6. How to write the composition "Let me solve the problem" in physical education class. In this class, the teacher not only won't let us run in circles, but let us hit sandbags instead! "That's great! Playing sandbags is my strength, I want to play well! "

The game has already started. Almost every time I throw sandbags, my classmates will break them off. After several rounds, there is only one opponent left-Zhu Jingyi. "Ha ha, you can't run away now!" I am secretly happy. The sandbags whizzed past, but the opponent was too clever to hit at all. We must do our best! I pretended to throw sandbags first and she ran in the opposite direction. This is, I came to a "high lob" and the sandbag landed heavily on her head. "Ha ha, fight, fight!" I cheered loudly with joy. At this point, I really admire myself for winning like a boy. That's great. So I went to other places to play happily.

After a while, a classmate told me in a panic: "No, you made Zhu Jingyi cry!" " ""how is that possible! "Just when I was having fun, I was shocked. He told me that I hurt her with a sandbag. " Go after her! She's going to tell Miss Liu! "

I chased her with a sprint speed of 100 meters, and she was too late. She has entered the office. "Ruined, this time you have to taste the taste of' what's so bitter about eating Rhizoma Coptidis'!"

Not surprisingly, soon, the teacher called me into the office. "Why did you hit her? Why not apologize? " The teacher's series of questions made me feel wronged. Why do you deliberately deal with the accident caused by my carelessness? I wanted to explain, but as soon as I opened my mouth, the teacher said, "Stop explaining, it's all your fault!" " "My tears immediately brushed off:" I didn't mean to, really! " "

At this time, I was a little excited and spoke loudly, which angered the teacher: "Go out and reflect in the hut!" " "

I walked out of the office angrily. When I arrived at the cabin, I was thinking about the solution to the problem: "Why don't you always listen to me?" Did I say something wrong? No. I must have spoken too loudly with emotion just now, and the teacher thought I had a bad attitude! No, I have to apologize to the teacher and explain. "

I knocked on the door, shouted a report and walked into the office gently. When the teacher saw me coming, she had a good attitude and calmed down. I apologized to the teacher and then said, "Teacher, it is wrong for me to hit people without apologizing. But I didn't mean to hit her, I didn't mean to! " After listening to my explanation, the teacher breathed a sigh of relief: "Well, since it was not intentional, go and apologize to her." I nodded and left.

When I found Zhu Jingyi, I told her the whole story. All misunderstandings have been clarified. What a relief!

When solving a problem, don't be impatient, calm down and things will be solved!

7. Composition topic: How to write a difficult problem?

There are countless problems in life, which always make people hesitate between right and wrong.

One day, I was preparing to go to Xinhua Bookstore by bus. On the way, there are more and more people on the bus, and there is not enough air in the crowded place. The bus turns sometimes and stops sometimes, which makes everyone roll back and forth. In the shaking, a passenger's wallet fell at my feet.

At this point, I either pick up the money and put it in my pocket, or pick it up and return it to the owner. What choice should I make? I hesitated. Oh, my god, why does fate ask such a difficult question to test me! You know, if this money is mine, I can use it to visit places of interest, eat KFC and visit amusement parks … carefree and free. But the problem is that the money is not mine. You can't be happy when you use it, only you blame yourself and fear. In this way, when I watch the beautiful scenery, I will feel dark, when I taste delicious food, I will feel tasteless, and when I visit the amusement park, I will feel uncomfortable ... This tiger who died halfway stumped me. "What should I do? What should I do? " I'm like an ant on hot bricks. I'm in a rash. So, I had another ideological struggle: my parents and teachers said that being a man must not be ignorant of money, and I will regret spending money that doesn't belong to me. In other words, there are many gangsters robbing and stealing in the newspaper recently. If I take the money without anyone knowing, will it soon be associated with crime? I don't want to do this ... Seeing that the owner was about to get off the bus, I decided to pick up my wallet and return it to my uncle who lost money. He even praised me as a young man who never forgets money! After listening to this sentence, I feel guilty and happy.

Life is like this. There are always things that make people hesitate. We should be wise and make the right choice.

One day, I wanted to take out the money in the piggy bank, but I couldn't find the key. I'm sweating with anxiety. I have no choice but to go to my mother.

Mother heard the story and said, "Think about it carefully and see if there is any other way, without the key." I thought about it for a long time, and suddenly it dawned on me: I can smash the lock with a hammer! I told my mother what I thought, and she nodded in agreement. I quickly found a hammer and smashed the lock several times. The lock really fell off. Mother asked, "Can you solve problems with your brain?" I nodded my head.

Through this incident, I understand that no matter what I do, I have to use my head. In the face of difficulties, as long as I am willing to think, use my head and work hard, I will certainly make continuous progress.

9. Write a composition that asks questions and then solves them. Overcome difficulties and overcome yourself _

I used to be a very timid girl. Too timid to be afraid of mice, too timid to sleep alone, too timid to stand on high and leave their parents.

I remember before I was five years old, my father took me to climb Xiyan Mountain. But every time, I skipped and came back sobbing. Until I was five years old. I'm so excited that I can finally spend my summer vacation. Because I can sleep until ten o'clock and play until ten o'clock. The next morning, my father pulled me out of the date with Duke Zhou and "ordered" me to get dressed and put on sports shoes. I was dragged to the foot of the mountain by my father with doubts.

"ah? Dad, no way, going to climb the mountain again? " "That's true, or when will your acrophobia be cured?" Although I was very, very reluctant, I didn't want my father to go home and torture me, so I had to bite the bullet and take my father's hand and climb up step by step. As the steps up the mountain were relatively gentle, we were halfway up the mountain at once. At this time, a temple appeared in front of my eyes, which was the place where I stepped back countless times. One stood in front of the temple, with ten high and steep steps. I can't help looking up. God, I'm still "intimidating" the two stone lions above! Dad saw my fear and used a "provocative" tone: "What, are you still afraid?" If I had known you were so useless, I wouldn't have brought you here. "It really worked. I was taken in by my father:" Who said I couldn't climb up? "Today, let you see the true skill of your precious woman."

I dragged my father a step forward. One is a piece of cake, two are really easy, three are ok, and four are ok. Seeing that I was almost in the middle, I cried with an "ah". Dad always said, "Don't be afraid, I'm still here!" " "But I am still embarrassed to say," I can't go up. I'd rather stay here. " When my father heard this, he immediately threw me aside and pretended to be angry and said, "All right, stay." Say that finish, he immediately took a few steps, I had to move forward with trepidation. Tourists look surprised and happy like us strange women. I, angry and anxious, can't wait to rush up and punch my dad on the thick fat layer. At this time, my father said in despair, "Would you like to come up? Then go. "Gradually, the ground is getting farther and farther away from me. Unconsciously, I have reached the door of the temple. The two stone lions also looked at me kindly at this moment, as if there were a little encouragement and congratulations in their eyes, and more, they were gratified.

Suddenly, my father patted me on the shoulder. Naturally, my head turned back. This major is not important, so I, a acrophobia, almost slipped and fell down the steps. Although I said "not afraid" in my heart, my body still shook unconsciously. Dad gently covered my hand and let me take a few steps forward. I did it. I don't know where I got the courage. I pushed away my father's hand, opened my eyes wide, looked at the tourists below and thought about my mountain climbing experience. I can't help liking this condescending feeling. At this time, a sense of accomplishment welled up in my heart.

Now that I am grown up, I can go up and down freely on the Xiyan Mountain, and I can even trot home from the narrow path. As I get older, I can stay at home alone for one night. All this is because I am afraid of mountains, which has benefited me a lot: don't be afraid of difficulties, only by working hard to overcome them can we reach the peak of glory.

10. Demonstrate and write a composition by asking questions, analyzing problems and solving problems. You were born with wings, why are you willing to crawl forward like an ant? Inscription.

Winter Yan returns to the south, singing softly. Time always turns quietly when people are unprepared. Summer insects sing again and again, silent, I almost feel sad, but I have clearly realized my situation: humble and slim, like rootless duckweed, like a lonely and desperate boat at sea.

At that time, "one person" was the most eye-catching theme in my memory. Eat alone, read alone and write alone. I am like a firefly, burning in the dark without anyone, and then quietly waiting for the announcement of death. Like autumn leaves, they fall alone, waiting for the next year to melt into the spring mud. As Zhu Ziqing said, "The excitement is theirs, and I have nothing." Without rebellion and noise, my youth was infected by nameless loneliness, and despair filled the whole world, and I almost suffocated.

In March, after a continuous drizzle, cherries turned red and plantains turned green. The playground is filled with an earthy smell, and some are fresh and straight to the nose. I sat in the classroom and looked out of the window. Pink-purple flowers bump into your eyes, just like the title page of a beautiful youth book. Inadvertently, I remembered a sentence on the title page: you were born with wings, why are you willing to crawl forward like an ant? A poet's puzzled question made me tremble in an instant. I dare not face it directly, because it makes my ugly and degenerate face appear naked in front of the world. Without the mask, how terrible I should be.

Huang Biyun said, "If one day we get lost in the crowd and live a mediocre life, it's because we haven't tried hard."

China scholars said: "I have a fallacy that scholars should die on the academic stage and dancers should die on the stage. In other words, a real person should devote his talents, talents and lifelong learning to the society and pursue it all his life until the sun goes down, and then his bones will last forever. "

Yes, we may not know the meaning of "living", but we have paid too much for it; Maybe we can't realize our dream, but we shed too many tears for it. And all we can do is on this road, and there are some farther. Heaven is not necessarily in front, but hell must be behind.

What we throw out today is a tomorrow that many people dare not expect.

In this sunny and rainy river's lake, I would like to take my dream as a horse and be at home everywhere.

You were born with wings, why are you willing to crawl forward like an ant?
