It was in a science class in grade five, and the teacher said to us, "Which one of you can cut the glass in half neatly without a glass knife?" We thought, "How can we break the glass without glass cutter?" The teacher seemed to see our ideas and said to us, "I'll give you an experiment." I'll tell you what it is when I'm done. " We all watched the teacher do the experiment with a grain of salt.
The teacher brought a basin of cold water in front. Someone brought a rectangular glass, a wire, gasoline and a box of matches. The experiment began, only to see the teacher dip the metal wire in gasoline first, then wrap the metal wire around the glass, hold the other end of the metal wire with his hand, pick up a match and light it around the metal wire. It took three minutes to fade out. Then he saw the teacher put the glass and the wire together in a cold water basin. After a minute, he lifted the glass, took off the wire, broke it with his hand and heard a bang.
As I watched it, I thought, why do you have to enclose the wires in the middle of the glass? Can't it be broken without that? By the way, isn't this the reason why heat expands and cold contracts? Thinking of this, I only heard the teacher say to us, "Do you know what this is about?" I raised my hand as soon as the teacher spoke. "Gao Wenxiang, what do you think this is?" The teacher said to me.
I replied loudly, "This is why heat expands and cold contracts. The iron wire heats and bakes the middle of the glass, so that the middle of the glass is heated, which is much hotter than the two sides. After the glass is put into the cold water basin, the middle is colder than the two sides, so the middle has strong contractibility and will be cut off from the middle of the glass by hand. " After listening to the teacher's words, a satisfied smile appeared on his face, and the students also cast admiring eyes.
I remember another time, when we were telling an ancient poem, the teacher was afraid that we wouldn't understand it and made up a fascinating story for us. This is the scene in the poem A Journey to Youth. The teacher told us, "There is a brave young man riding a big horse with a bow in his hand. His skill is very high, he can open the bow from left to right, and he can hit every shot. Surrounded by the enemy, he didn't panic at all, calmly fought and shot many enemies.
When I heard that, I felt as if I had come to the battlefield and saw their fighting. After the teacher finished, I was still in a daze. A classmate stabbed me and I woke up.
The teacher's teaching method is really good. I want to be a teacher when I grow up, and I also use this method to teach students, so that students can better understand the consciousness of poetry. Although these two things are common, they have taught me a lot of knowledge and made me understand the truth that learning knowledge should be applied.
When I realized that primary school life was over, I had an infinite attachment to it! In the embrace of my alma mater, I am like a seedling, bathed in warm sunshine and sucking the sweet rain and dew. Under the cultivation of the gardener, I grew from a childish child to an enterprising teenager. Military training began in our grade and went to Huangpu Military Academy. After dinner, we went to bed.
The next day, a sharp whistle woke me up from my dream. I opened my eyes and saw other students getting dressed. I sat up at once. My coat was gone, but all the other students ran out.
I was afraid of being punished by the instructor and rushed out, ah! How cold it is! What? To run, I wear short sleeves and run with my classmates. I see Li Siqi's coat behind me with my name on it, but she is my best friend. Sorry to say, it's really hard to say! Alas! One thing in the class began. Teacher Li, the head teacher, came to the class and began to choose candidates for the Chinese group. I sat in my seat and listened attentively.
"Liu Yucen and Chen Zhiying will go to the library, and Leng Jianshu will go to the PE teacher. Liu Yucen, production airlines, Wu Ziheng, Li Zhengwei and Ma Mingjun will go to China interest group tomorrow. " After Mr. Li finished speaking, Yang didn't hear the name of China interest group, so he patted his chest and said, "It's a close call without me."
The voice was not loud. Teacher Li heard it and added: "And Yang Yun Si!" The whole class laughed, but Yang said, "I'm so miserable!" On an autumn outing in grade five, we set off with a bag of snacks on our backs. After dinner, we went into our group room and closed the door. Four people in our group decided to stay up until dawn. While we were playing games, one of them accidentally fell down. We also watch TV.
It was very hot, so I turned down the air conditioner to 16 degrees. Finally, at 5 o'clock, we were tired and fell asleep on the ground. Someone knocked at the door and we all woke up. One of my socks is missing because the room is too messy.
In the group, everyone caught a cold and had dark circles. Because the air conditioner was turned on too low, Teacher Li came over and touched Liu Yucen's forehead and said, "No sleep!" My primary school life is over. In this unforgettable life course, the sweet rain and dew moistened me, the sunshine of the party nourished me, and the hard work of the teacher watered me. How can we not miss primary school life and teachers? My primary school life is like a dream, a colorful dream, which makes people miss and yearn for, and often brings me good memories! On that day, several classmates and I will go to the middle school affiliated to Guangxi University to take the entrance examination. The teacher called us together and told us earnestly: "The biggest problem of our classmates is that they are not careful enough and have no patience. In this exam, you must remember the six words I once told you: concentration, carefulness and patience. I believe that with your real level, you will be admitted to the exam ... "The teacher's concise language summed up the matters that we should pay attention to when going to the exam.
I looked up at the teacher and found that the teacher's eyes were like a clear spring, which cleared my heart; Like a fire, it warms my heart; Like a gust of wind, the sadness in my heart was blown away ... and there is another thing that I will never forget. When the teacher read my name and reported my score, my heart sank and I thought, Oh, my God, 8 1! The fifth from the bottom of the class! This is the lowest score of my primary school life. What will the teacher say? What will parents say when they go home and sign for their parents?
2. What is the composition? 23 things, 500 words and 600 words. From school to now, I have sat at the same table with many people.
But the closest and best relationship is Sun Chao, who is quick-witted, quick-witted, studies well and loves sports! He is the same age as me. He is a child of the Hui nationality. He has a Zhang Yuanyuan face, a high nose and big ears. A pair of thick eyebrows always seems to convey wisdom and friendly information to you.
Sun Chao's clever and quick response. Every time the teacher asks a question in class, he is always the first to raise his hand and answer it correctly; Every time the teacher asks us to write a composition, he always writes a good article in a very short time; Everyone likes to discuss problems with him after school. We sincerely admire his understanding and mastery of knowledge.
Sun Chao studies very hard. He comes to school on time every day and listens carefully in class.
Sometimes after class, other students go outside to play, and he still sits there reading. Every time he comes home from school, he always finishes the homework assigned by the teacher first, and then previews the lessons for the next day.
If he has time, he will read some extracurricular books. What "Chinese Volume A", "words and sentences" and "excellent composition of primary school students" are all things he has to do and read every day.
In order to expand his knowledge, he also asked his mother to enroll him in off-campus composition classes and Olympic math classes, and often used holidays and sundays to study. Because he studies very hard, he can get good grades in every unit exam, mid-term exam and final exam. He likes physical exercise very much.
He is not only serious about going to physical education class, but also active in his spare time. He likes swimming very much.
Whether it is hot summer or cold winter, he can keep swimming and exercising. On the wall of his small bedroom, more than a dozen awards were posted in the swimming competition alone.
Because he is active, he often "gets into trouble". Once after school, he and several of our classmates played the game of "catching people" in the corridor of the classroom.
We chased each other and had a good time. But accidentally, he bumped into a second-grade little brother, and his little brother's eyes hit him right on the chin.
As a result of overexertion, my little brother's eyes cracked a one-centimeter-long hole, and the blood flowed, which frightened us. At this time, the teacher came, called mom and dad, and sent my little brother to the hospital to "sew".
To this end, teachers and parents severely criticized him, and we also wrote a check to the teacher with him. Because I have a very good relationship with Sun Chao, when we sit together, we often whisper in class, and sometimes we do some little tricks.
Once in the "Sipin" class, our little tricks were discovered by the teacher. After class, the teacher asked us to stay and write a check.
We all regret it. In order to be strict with myself, I took the initiative to find a teacher and asked for a seat adjustment.
We are in a class, a classroom and a seat. We often study, play and play games together.
We care about each other, learn from each other and help each other, and we will always be good friends.
3. Semi-propositional composition "~ 23 things" 500~600 words 23 things on the first day of campus life
Aren't we just a nebula? Have the same enthusiasm as light, heat and fire. ...
Our campus life, like a kaleidoscope, shows a colorful world.
Listen! The whistle sounded and the tug-of-war began. We girls tried our best to cheer for the boys in our class, but these boys were so disappointing that they lost the first battle. The girls were hoarse with anger, but the boys were defeated. Really boring! Looking over there, the dejected boy actually put on a smug look again: "The third place is not bad! If you are not pleasing to the eye, you will not cheer tomorrow, so that people can quietly appreciate your flustered' heroic'! " Listen, it's "frustrated" and "heroic" How hateful! "Hum! It makes sense to lose! Self-deception, you can say it! " There are a lot of angry words! The next day, the girls went into battle. To our surprise, all the boys, including the leader of yesterday's "war of words", let go of their wild voices: "Come on! Come on! " Their rough noise was mixed with the shrill voices of several female compatriots who did not participate in the war. At the moment, I think this is the most magnificent music in the world. It twisted in front of us like a rope and became an inspiring song. Encouraged by this, the girls played a beautiful "quick victory" and won the first battle! "Oh, oh! We won, we won! " Yesterday's regrets and complaints disappeared in an instant, replaced by cheers! After all, we are in a group, and winning glory for the group is our goal. Today, we have achieved this goal again. How can you not be happy and excited?
Two look! Why is the classroom atmosphere in our class so warm? It turned out to be an interesting math class. Time to ask questions. As usual, the students think positively: this step proves unnecessary. Oh, no, the problem won't be so simple ... Gee, this proof is too complicated. Can you find another shortcut? .. a hands raised one after another. There are usually big boys and quiet girls. At this time, they are all like a different person, bold and cautious, asking novel and ingenious questions. "Bell ..." "Alas, how the class is over! Reprinted from the percentage network, please keep this mark. How time flies! " Of course, after class, the teacher is surrounded by a group of students who love thinking ... "I am particularly willing to go to Class 60, because students love thinking, are willing to use their brains and dare to raise objections ..." Listen! This is our teacher's evaluation, and we are proud of it!
Three "All the days, all the days have come ..." Who is so full of * * * to eulogize long live youth? "Maybe you haven't noticed, maybe you don't believe, how many people envy you for being young ..." Who sang "While you are still young" so affectionately? Who took a light step with the melody of the song of youth? It's us. This is our weekend party. Please come here. When you come here, the tension and fatigue will disappear. Do you know that?/You know what? We can study and live!
Time flies, our campus life is constantly changing color, and joy and distress follow. However, we love campus life, because it is a life of fire and poetry, and this is the real life! Oh, our campus life is like the moon, with ups and downs, joys and sorrows; Another example is the kaleidoscope, which shows a colorful world. ...
4. The composition "Two or Three Things of xxx" is 500 words and two or three things
The person I want to write is a famous problem child, very lively and naughty. There is no one around my home who doesn't know his name. This problem children is my little cousin, Wangwang.
"Oh, what are you doing? Put it down quickly. " "Come after me, hehe." Well, Wangwang started his trick-or-treating plan again. My classmates and I are sitting in the yard doing our homework. He grabbed my exercise book and ran away. As he ran, he looked back to see if I was chasing him. Did he make faces at me? I ran after him until he was tired and he didn't see the situation clearly. I will give you my candy, and when I grow up, I will buy you new clothes. "Of course, I won't believe his sweet words and chase him. This is what he has killed. " Mom, mom, sister, she bullied me again. Come on, just me, "he said, with a hint of" hypocritical "tears in his eyes.
My little cousin is a poor man. There must be something lovely about him.
In the morning, my mother and my little cousin came to the downstairs community to watch those uncles and aunts fight. "Hey, hey, hey", there are some slogans behind them. I turned around and saw that it was Wangwang. He just followed the crowd and imitated them in boxing, with a left hook and a hook. His expression is serious, but it is also funny, which makes me laugh. I didn't expect a naughty one to be like this.
This is my little cousin, very naughty and lovely.
5. How to write a 500-word composition about two or three things in junior high school life? Summer dusk is always so beautiful, as if it has the ambiguity of the whole world.
The fiery sunset is like a girl's blushing face, and the surging heartbeat reveals my deepest secret. I want to blow, the wind from summer solstice is the freshest, and there seems to be no heat this summer.
Xia Feng touched her face, and her hair fluttered gently in the reddish sunset at dusk, as beautiful as dancing lace. Rainy season ... same sky, same thoughts, same blessing, but different dusk.
Bicycle … parked on the grass not far from the lake, so quiet, so quiet … The air is intoxicating, so faint, but so cold, so light, but so strong. In the sky after the rain, the fog is enchanting, and the humid air exudes the breath of summer solstice.
Is summer coming? So, is the rainy season coming? Seventeen, that year. Look at her around her, her eyes are as bright as sea water, and she has shallow dimples when she smiles.
I like talking about him in her ear. How young and handsome he is in his dream, like Prince Charming in a fairy tale. She always listens quietly, with a faint smile in the corner of her eyes, like a happy angel, and the silvery laughter sows the seeds of happiness in her heart.
At dusk after the rain, two girls of the same age rode bicycles, and their happiness gradually fermented in other rainy seasons in summer. The melody of youth flows slowly, it was the age of cycling, it was the youth at dusk, it was the rainy season for girls.
The evening sunset burns up half the sky, charming sunset glow and intoxicating past events flow quietly in my heart, like a summer solstice stream, quiet but far away, and the past events hidden in my heart, such as wind, water and fresh air after rain. Is she okay? Is she still happy? Does she have to laugh as before? Will she remember me? ..... The bicycle in the corner, covered with cobwebs, stopped there quietly and inadvertently noticed the lonely figure of the bicycle. Is it forgotten in the corner? Has it been waiting? Has it been looking back? So, what about the youth at dusk? It is there waiting for the owner of memory to pick it up again. Where is it? .
6. My friend's 23rd essay is a 500-word past, like a trickle, following the footsteps of my childhood and gurgling out. ...
I once had a very good friend-Sunseeker. Sunseeker is a little taller than me, one year older than me. I observed her face carefully. The full moon face, eyebrows and hair are all shiny, and there is a delicate atmosphere in simplicity. When I smile, there are two dimples in my mouth, which are both pure and handsome.
In a test, my composition was poor, even not up to the intermediate level. The teacher didn't scold me or say anything about me, but gave me a meaningful look, as if to say, "Moya, how can you write such a poor composition when your learning level is above average?" Seeing the teacher's eyes like this, my bottom line finally collapsed and I was desperate at the same time. I cried for a whole recess, and I crawled on the desk with tears in my eyes. I seem to hear sunseeker say to me, "Life has its ups and downs. In the face of setbacks, we must have firm will and belief, bravely face setbacks, challenge difficulties, and never give up until we reach our goals. " Dai Jing, how can you cry with this little setback? "I suddenly looked up and saw her smile, as warm as sunshine, and let me bathe in it. Yes! How should I despair? How can I give up? Yes, I won't stop until I reach my goal! Finally, my efforts paid off. If it weren't for sunseeker, I would have given up ... everything became clear. It seems that I have to thank her!
7. Ask for a 500-word composition: Two or three things about me When my thoughts flew to the ends of the earth, I suddenly heard a loud name.
The sound is enough to drag my thoughts back. "Zhu Bingsong, recite The Hard Road!" I stood up in a hurry.
Have you ever studied Shu Dao Nan? I thought to myself. I looked left and right, and no one called me.
I groaned for a long time, but I choked out a sentence. Teacher, I'll let you recite it tomorrow. The teacher glared at me for three seconds and told me to sit down.
I sigh. My deskmate immediately sang a congratulatory song to me: "Congratulations, congratulations, congratulations, every year has today, every year has today, congratulations, congratulations …" I was so angry that I gave my deskmate a hard K when I vomited blood.
At the same time, the teacher asked several people to recite Difficult Shu Dao, and those people recited it faster than tongue twisters, which really made me admire to death. I've been working hard all day and I haven't recited it yet.
God, help me! I decided not to pursue the ideological struggle in math class. Anyway, death is not death, but also afraid of this time? This decision proved my correctness. The Chinese teacher seems to have forgotten this day not to criticize me.
I dodged a bullet. Since then, the Chinese teacher has never asked me to recite the text.
NO.2 was having fun playing underworld in the Internet cafe when he was slapped by a * * * who came out of nowhere. I was just about to start cursing when I turned around and saw, wow, old Ben, I'm dead! With a sinister smile, the old class smiled and said to me, "Come to my office after you play."
After what? Can I still play? Go if you don't want to die. When I arrived, I found a row of friends standing outside.
I smiled and said, "Share weal and woe and overcome difficulties together." They also laughed: "Brother, you have also been arrested. Where are you? " I chatted with my friends as if nothing had happened.
I counted that there were seventeen people. We really added face to the old class.
When the old class came back, we immediately fell silent and stood there. The old class invited several of us into the office and closed the door, giving us a rather boring exclusive political lesson.
This is exclusive. The old class was very satisfied with his political class and waved: "Everyone should write a letter of guarantee after returning, and the content must be profound!" We walked with heavy steps and left the office with our heads down.
As soon as we got out of the office, we were all complacent. Letter of guarantee, nothing, write N+ 1 time.
I find these people really thick-skinned. Our math teacher is a genius.
She can recite a page and a half quickly in a class. I was at a loss in her class.
I'm fed up with her math class. I finally got up the courage to say a very exciting sentence in her class, which was too fast to understand.
I'm sure her ears must be bad. As usual, she went on with her class as if she didn't hear.
I threw the paper into the dustbin in a rage. I decided to teach myself math.
I will definitely give the teacher a surprise. Come on! Let time prove everything.
