This incident taught me a painful lesson, and I will never do it again!

Mom wanted to go out, and before she left, she said to me, "Choose the oily wheat dishes on the table, and then wash them!" "I replied," Oh, I see. "After my mother left, I sat on the sofa and began to choose vegetables. I picked out the yellow, old and rotten leaves, then pinched off the roots with soil and chose a lot of oil wheat vegetables.

I came to the kitchen with this pile of plates. I wanted to suffocate before washing, so I blocked the mouth of the pool with a plug. After blocking, I put the spinach into the vegetable sink and unscrewed the water pipe. The sound of water coming out is a little loud, and then I slowly twist it to the left, and the water gradually becomes smaller, reaching the desired water potential, as thin as chopsticks, and hitting the spinach placed in the pool.

I think: the water won't overflow for a while, so watch TV first! I ran to the TV with a smile and turned it on. I found my favorite TV series and watched it with joy.

Before I enter the climax, I think it is almost ready. Go and have a look. "Is this the best part?" I was about to watch it, but I was attracted by the seemingly wonderful sound of the story on TV and looked back curiously. "It's really wonderful!" I am fascinated by watching TV. Ignoring the sound of running water in the kitchen, unconsciously, a "disaster" came.

After the climax, the result is that the bad guys are caught and the good guys get good returns. While I was delighted with this result, I vaguely heard the sound of running water and suddenly remembered "spinach, water!" "

My originally happy mood suddenly became sad and regretful. I ran to the kitchen in a panic, and the scene before me was: there was a layer of water on the kitchen stove, and the water on it was dripping down the countertop. Look at the kitchen floor, too

I was shocked by the messy kitchen, so I quickly brought pots and pans and dragged them on the floor. Sweat mixed with water on the ground, which made me forget TV. One minute I wring the water off the mop, and then I drag it. I am as busy as a bee. I finally cleaned up the water, haha! Spinach floats out of the pool and is washed with water. I blame myself. Don't be half-hearted in the future!

From this, I understand a truth: no matter what you do, you should stick to it wholeheartedly, not half-hearted, time-consuming and laborious. I will never do such a stupid thing again!

Many people, because of their complacency after success, quickly went to the road of failure; There are many people who have ushered in glory after modesty. "Pride makes people lag behind, and modesty makes people progress." I was deeply moved by this sentence.

I still remember that I got a hundred points in the math monthly exam last time, and then I rushed home excitedly and said to my mother, "Mom, look at me, I got a hundred points!" " "My mother was also very happy, praising me and encouraging me. But when she saw me show off in an ostentatious manner, she quickly lowered her face and said to me seriously, "Baby, 100% is really great. This is undeniable. Mom is happy for you. But this achievement is not only because of the hard work of the teacher, but also because of your attitude of studying hard at ordinary times. You can't be complacent just because you got 100 in this exam. There will be many exams in the future. Only down-to-earth ... "

"I know, I know ..." I interrupted my mother impatiently and waved to her. "I went to review." After that, he went into his cabin, closed the door, took out his mobile phone and secretly played.

A few days later, we finished the new course. The teacher said that we would have an exam tomorrow. The students were very nervous, but I didn't agree. I thought, "Come on, it's just a unit exam. The monthly exam is still a hundred points. Can the unit exam be lower? "

So, when I got home at night, I didn't even turn over my math book or review it at all. My mother urged me to review again and again, but I laughed disdainfully. On the surface, I promised well, but in fact I was not worried about the exam at all.

The next day, the exam began. I was blinded when I saw the paper, because I couldn't do several questions, which were all told by the teacher in class! Just because I was too proud to listen carefully. After the exam, I was like a wounded deer, lying on the desk feebly. How I wish the teacher would slow down and never get a grade.

In the end, I couldn't escape the announcement of the results. At that time, I was so nervous that my heart was like fifteen buckets of water-up and down. Sure enough, I didn't do well in the exam, and several students who didn't study well at ordinary times ran in front of me. I looked out of the window with a decadent hammer on the table and regretted it very much. I feel that even the chirping birds outside the window are laughing at me, and the young trees are blown aside by the wind and don't bother to look at me. They all seem to say, "make you proud, make you proud, aren't you beautiful?"

Although I failed the exam this time, the teacher didn't criticize me; Although my classmates didn't laugh at me; Although my mother didn't criticize me too much, I learned a great lesson. I will always remember this exam and remember that "pride makes people lag behind and modesty makes people progress." The true meaning of this sentence.

In my life, I know that there are more grains of sand in the ground and more stars in the sky. But I always go in one ear and out the other, and I haven't learned any lessons at all. However, I was deeply impressed by that lesson.

That summer, it was very hot. My mother bought a lot of ice cream and told me not to eat too much. I can only eat one a day. On that day, the sun almost scorched the trees, and people were afraid to go out to the streets, so they all hid at home and turned on the air conditioner to cool down. Of course, I am no exception. I turned the air conditioner to the lowest gear and the fan at home was turned on to the maximum power, but I still felt so hot. My mother was taking a nap in her room at that time. I cleaned up, crept into the kitchen, opened the refrigerator, and a cool breeze came on me. It's so comfortable There are countless ice creams in the refrigerator, and I can't help complaining to myself: "I can only eat one ice cream a day, mom, how stingy!" " I took out an ice cream and ate it happily. I still wanted to eat one, so I forgot my mother's instructions. I picked up another one, two, three, four ... suddenly, I felt a stomachache and my brain began to heat up slowly. After a while, I fell asleep in a daze.

When I woke up, it was the next morning. At this time, I was lying in the hospital. My mother told me that I had a fever at night because I ate too much ice cream. Fortunately, I didn't eat too much. If I eat too much, I have to be hospitalized for surgery. After listening to my mother's words, I threw myself into her arms and sobbed and said, "Mom, I will never steal ice cream again, and I will never pay attention to your words again."

This lesson taught me not to overeat. Learning can't be cold, you should take your time and keep your feet on the ground, so that you can succeed. Above all, don't turn a deaf ear to what others say, listen and learn from it, and don't make the same mistake again.

Lessons are the key to success, the only way in life, and a ship that can let us enter our study career. ...

It was a winter afternoon, and it was almost New Year's Eve. My parents are busy helping my grandparents. Only my brother and I are free and don't have to work. I was bored, so I played chess with my brother. I briefly talked about the rules and moves of chess pieces. I thought my brother was a novice, so I got off the bus with him in a casual attitude. It's warmer outside with no heavy snow. I looked out of the window and occasionally glanced at the chessboard with my eyes, but my heart couldn't help flying out of the window. In this way, I played several games of chess in a row, but to my great surprise, my brother's sense of chess was very good, which made my back sweat. He attacked my weakness again and again. If I knew, I wouldn't underestimate my enemy. All the places where I let my son go have been breached, leaving only the Lifeline Queen to protect the king. Now this chess game is like two big trees: one is that all the roots are deeply rooted in the soil, while the other is only rooted in the soil, and it will fall down at any time after the storm. But I'm still dying. Unfortunately, the queen died heroically in the fierce battle, so I had to give up.

Lessons; Just listening to the name makes people sad, but on the other hand, lessons can also make us correct our mistakes and strive to grow.

"I have already talked about this problem in class. How can you be wrong? " "hmm? Who's talking? It seems ... it's teacher Zhu. According to the sound, she is trying to restrain herself ... "I secretly looked up and saw Miss Zhu at a glance. She looked down at her classmate's exercise book, frowning, and her eyes behind the glass lens seemed a little angry. ...

The students at the back of the podium, like a turtle, huddled their heads in a collar with blue, red and yellow vertical stripes staggered into a square, their heads drooped slightly, their eyebrows drooped a little, and their eyes trembled at the ground. I can't help but feel his thoughts, and everyone is shaking.

He stood hunched over ... no, he seemed to be crouching behind the podium. The podium was badly painted by the last batch of students, and there was an unusually conspicuous pig, Bajie. The east is painted with a piece of "Qing Wu" and the west is painted with a piece of "Qing Wu" podium, which seems to be accompanied by his (that classmate's) heart, crying and making me feel like being cut by a knife.

"Still not quick change? I told you for nothing? How much is this question 760×8=? " "Little puss-head" classmate still shrank, and suddenly, he quickly jumped back to his seat.

Suddenly, I think I was wrong, too! I quickly and quietly took back my exercise book, calculated the answers carefully again and corrected them.

After this, I know I must listen carefully in class!

Many things happen every day in life, some are trivial things, and some will also affect our lives. Society is complicated. As middle school students, we don't know much about it. That incident taught me that society is not very beautiful.

There is a small shop in my home. Although the shop is not big, business is still booming, especially on weekend nights, the two rooms are always crowded with people. At that time, I was also the "small boss" at home. Although I am a "small boss", I can manage my business in good order, so I always help to look after the shop on weekends.

It was a Sunday afternoon and a stranger came from outside. He is not tall. He wanted to buy a nutrition express and paid for it. Then I ordered a pack of cigarettes, 1 1 yuan. He gave me 10 1 yuan. I should call him 90 yuan. After I got the money, I first looked at this bill of 100 yuan, which was brand-new. Because dad said that the newer the coin, the greater the possibility of counterfeiting, so I looked at it again. I've read it, no problem. I started looking for change. Suddenly, he said he had change. "Yes, whatever." I returned the hundred-dollar bill to him and took a 20 yuan. After receiving this bill, I found a big horn missing. I returned it to him without hesitation: "This money can't be used, you can change it." "Never mind, just a little less," he said. "I lost a corner. This is obviously a waste of money. Take me as a three-year-old child? " I said angrily in my heart. I got back 100 yuan and went to see him, 90 yuan. He left without looking, and forgot to take the nutrition express.

I think this man left in such a hurry that he forgot to take his drink, so I can make a profit from 4 yuan. In the evening, I discovered that this was a fake coin! What a clever liar. Inadvertently, he changed the real money into fake money! I was very angry after this incident. As my mother said, 100 yuan is enough for a class. Be more vigilant next time. Here, I hope people will take a warning, walk cautiously to the society and prevent being deceived.

In modern life, as a high-tech product, mobile phone has become the most important companion around us. We take it with us anytime, anywhere, when we pay, when we travel, and when we encounter problems. With it, people's lives become both convenient and rich. Mobile phones are people's life assistants, but when assistants fall into the hands of students, they often become demons.

As we all know, for students, mobile phones can help students learn when they can't answer difficult questions. Then why does the mobile phone become a demon? This answer can be found in what happened around us.

I am a junior high school student, and I am very happy to get my own private mobile phone by chance. Because the school has a rule that you can't bring your mobile phone to school, so I always put it in the drawer of the study desk.

One day, my brother was doing his homework in the study and I was reading in the living room. Occasionally I heard a "hee hee" laugh in the study. Why is my brother laughing and secretly laughing? Curiosity drives me. I tiptoed into the study. There is a desk in front of the window of the study. I looked around and saw my brother playing Clash of Tribes on his mobile phone! He still has unfinished homework on his desk. I leaned down and he was stunned. Seeing it was me, he secretly said to me, "Sister, do you want to play with me?" Many students in our class are playing this game. "I'm curious about what game it is, so I play mobile phone with him. An hour or two passed quickly, and we found that our homework was only half finished. I'm afraid my father will find that his homework hasn't been finished yet, so my brother will finish it quickly and let me help him write something to keep a diary. In this way, the summer vacation soon ended and the new semester came. My brother and I both jumped into a pair of glasses. My brother and I both learned our lesson!

This is why I say that mobile phones are sometimes demons, because they are the killers of myopia. Students like us, in particular, do not have good self-control ability, and it is easy to cause some damage to their eyes. According to the survey, the nearsighted people in China are mainly teenagers, so I want to tell you that you should control the time of using your mobile phone, or you will end up like me!

"Ding ... Ding ..." The bell came as scheduled.

When the teacher walked into the classroom and pushed open the door, an imperceptible smile appeared on his mouth: "Students, let's prepare for this class!" " "

On hearing the exam, everyone protested: "Didn't we just take the exam a few days ago?" Why do you still have an exam now? The teacher turned a blind eye: "This paper is a test of IQ." Whoever gets full marks is a genius. "

At this time, there is a happy face, as if it is time for him to show his talents; There is a face of depression, as if he is going to fall into Sun Shan again; It doesn't matter, it seems that everything is meaningless to him. If I don't get good grades in Sun Shan, I will be laughed at by my classmates. If I do well in the exam, I can show off to my mother at home.

We picked up a pen and did it seriously. We were silent, and only the sound of paper and pen fighting was heard in the classroom. The first question: after reading the test questions, is this still a genius test paper? This is the first thing we do in every exam; The second question: write your name in the upper right corner. Since our kindergarten, although there are not thousands of papers, there are at least hundreds. Isn't this unnecessary? The third question: name plus pinyin. Do you still think we are children of Grade One? This is a piece of cake for Zhang Fei to eat bean sprouts. The fourth question, the fifth question ... the seventh question, but there was a "haha" voice in my ear. Alas, isn't this Xiao Jiang? He finished 20 questions? Usually it's a turtle, so I finished it so quickly today. Is there any fraud in this? I read one question after another according to the requirements of the topic. When I saw the twentieth question, I suddenly realized that I only need to finish the second question! I did it quickly, and then I looked at others. Some people craned their necks and tried to get something for nothing. Some frowned and seemed to be thinking hard.

"Time's up-"the teacher commanded, and there was a sigh from time to time. The teacher asked us to read the twentieth question, and everyone woke up like a dream. Many students' faces are full of disappointment. The teacher repeatedly stressed the need to examine the questions carefully, but everyone ignored them.

We must carefully examine the questions in the future, otherwise the jokes will continue to be staged on us.

Childhood is a beautiful beach, but there will inevitably be some stumbling blocks on the beach. Standing at the window, the sky outside reminds me of my childhood.

My mind kept turning, and I saw an aunt standing in front of me. She pointed at my nose and said, "You are a bad boy, a bad boy who can lie." My tears can't help spinning in my eyes.

It was a beautiful morning, just like today. The sun shines into the room, which is very warm. I stretched myself and got out of bed. My mother is busy in the kitchen. She asked me to buy her a bag of salt. I was very happy to help my mother, and I readily promised my mother. After receiving my mother's money, my mother told me, "A bag of candy 1.5 yuan. Remember to get the money back. "

I skipped to the nearby store with the 5 yuan money in my hand. Standing in front of the store, I saw the beautiful aunt in the store. She has shiny black hair and bright eyes. "What can I do for you, little friend?" Aunt asked me in a sweet voice. I stood on tiptoe and said, "auntie, I want a bag of white sugar of one yuan and fifty cents." Aunt smiled and said, "OK, just a moment." After a while, my aunt handed me a pack of candy. I gave 5 yuan money to my aunt, and she gave me 3 dollars and 50 cents. When I walked out of the store, my aunt and my mother told me to take the money well. I nodded, put the money in my pocket and ran out of the store with a smile.

I ran home as fast as I could, but when I was at the door, I touched my pocket. "My God!" "The money in my pocket is gone. I seem to have been put into the freezer, and suddenly I was cold from head to toe. I hurried back from the original road and looked for it again, but there was still no sign of the money. At this time, I panicked. I really hope it's the Monkey King who can pluck the monkey hair and turn it into 3.50 yuan.

I dawdled home and handed the sugar to my mother. My mother took it and asked, "Where is the money?" I said hesitantly, "Money ... money ... is lost, no, money ... aunt didn't find it." Hearing this, my mother flew into a rage and took my hand to the store. Mother asked her aunt at first, "My child came to buy sugar. Why don't you change it? " Bullying him is a child, right? "Aunt said doubtfully," I found it! "You ask your son." Mom is even more angry, and it is clearly written on her face: My son is still cheating?

Mom still asked me, "Did you find the money?" My face is flushed, and I dare not look my aunt in the eye. I said in a voice that only I could hear, "No?" Aunt and mom still heard it. Aunt shook her head, revealing a helpless look. Then she took out three dollars and fifty cents from the till and gave it to her mother, saying, "Sorry, I forgot to change it." Get my money back. Mom took me away.

Later, I heard that my aunt's shop moved away. I wonder: Did I embarrass menstruation by lying, so menstruation moved away? To this end, I cried in the room and silently said sorry to my aunt.

From then on, I remembered that lesson and stopped telling lies.

It was a winter vacation, my cousin came to my house to play, and we did something together that I will never forget.

We turned on the TV, and the children's favorite sharpshooter was playing. I especially like the toys "Galen Yanlong" and "Oinggert" in it. Moreover, we also know that these toys have been sold in the market, but we have no money to touch our pockets. Cousin Grinch rolled his eyes and said to me, "There is a way." I hurried forward and asked, "What should I do? What method? " He smiled coldly and said, "Why don't we take some from your piggy bank?" I quickly shook my head and said, "No! No way! My parents will be angry when they know. " "You don't say, I don't say, how do they know? It may be bought by others in the future. " Cousin said anxiously. I decided to try my luck for Gallon Dragon.

We got our favorite toy as we wished. That kind of excitement has long made me forget the anxiety when I took the money. Just as we were having fun, my mother came back from work. She saw the new toys in our hands and asked us, "Who bought you toys again?" I didn't dare to look my mother in the eye, so I lowered my head and whispered, "Dad bought it for us." So I lied to my mom.

Things didn't go as smoothly as we thought. When dad came home, his mother scolded him, "Why do you buy toys for your children all day?" Dad was confused and said innocently, "There is no such thing!" "I was very nervous at the time. I felt at a loss when I saw my mother's livid face.

My mother called me into the room and asked what was going on. I have to tell the truth.

Mother sighed sadly and said, son, do you know how big a mistake you have made? Not only did he steal money, but he also lied. The ancients said that they stole needles when they were young and gold when they were old. If you form this bad habit at an early age, how can you get a foothold in society in the future? Life can't blossom brilliantly in lies, and honesty is the foundation of our existence. Honesty is to people what roots are to trees. Without honesty as the foundation, the tree of life cannot stand upright.

After listening to my mother's heartfelt words, I was ashamed to say to her, "Mom, I was wrong, please forgive me!" " "My mother touched my head and smiled knowingly. I want to firmly remember the sentence "Honesty is the foundation of being a man". I believe that with these, I will be like a tree with soil, infinitely moist and thrive. I will always remember this profound and unforgettable lesson.
