Write 500 words in an interesting class.

No matter in study, work or life, everyone will be exposed to composition to some extent. Writing is an important means to cultivate people's observation, association, imagination, thinking and memory. So, how to write a composition? The following is an interesting 500-word class composition I collected, hoping to help everyone.

An interesting class composition is 500 words 1 "Ding, Ding"! The students rushed into the classroom as soon as the bell rang.

Everyone is looking forward to the arrival of the English teacher. Suddenly, someone came! Everyone stared at her intently, and their hearts were full of doubts: who is she? She seems to have a pair of the Monkey King's eyes, read our minds and said, "Hello! I am your English teacher this semester. My surname is Shen. You can call me Miss Shen. "

In the process of learning English, we not only know how to read and write, but also have fun in Le Duoduo.

One interest: burying mines.

The teacher said to us, "Let's play an interesting game,' Bury Landmines'. I think everyone has played! " We all said, "Yes!" Rule: The teacher makes a mark under a word, and that is mine. After erasing the mark, as long as a classmate reads the word buried mine, it will immediately "detonate". Here we go. The mines are a, c and F. In the first game, several students detonated the mine-"three, two, one, boom!" " In the second and third innings, the mines were detonated one after another. After the game, some students proudly showed off to everyone, while others were depressed. Why are they so careless? Some students stamped their feet angrily. This game is really called "Earth-shattering, make the gods cry"!

Second interest: delivering packages.

After the first game, the teacher took us into the next game: the teacher began to pass flowers from a small group of people. When the teacher calls to stop, the person who gets the flowers should read the words ordered by the teacher. Otherwise, he will perform the rooster lay eggs. The competition started, and the flowers slowly spread to Xiao Xia. At this critical moment, she spread the flowers to Xiaotian. The teacher pointed a word with a pointer, but he couldn't, so he had to perform on stage. The students leaned forward and backward with laughter and slapped their desks. Xiaotian also smiled shyly on the podium. There is laughter in the classroom.

After class, the students reluctantly said to the teacher, "Teacher, goodbay!" "

This English class is really interesting!

An interesting class composition 500 words 2 This afternoon, it was raining in Mao Mao, but it didn't affect my excitement at all, because I was going to Boda to make up my composition.

When I first entered Boda composition class-Zhong Da Garden. It's like walking into the ocean of knowledge. As soon as the bell rang, the long-awaited composition class began, and the content was to find coins.

The search for coins began, and the teacher asked the first "little scout" to speak. He walked up confidently and stared at the trash can as soon as he came on stage. He hunched over to the trash can, his eyes still scanning the ground, looking for the shadow of the coin. When he came to the trash can, he carefully looked inside and outside the trash can, picked up the fire extinguisher next to the trash can, but found no clues. At this time, zhangyan was a little depressed. Finally, he lowered his head and returned to his seat.

Then came Zhang Lei, who looked around but found nothing. The students talked about it in succession: "trash can, trash can, it must be in the trash can!" " "Zhang lei listened to the students' crying and really went to the trash can to find it. At this time, she found a piece of waste paper next to the trash can. She picked up the waste paper, looked at it, looked at it again and again. She tore open the paper outside and saw a paper ball inside, perhaps because she thought it was impossible to be inside! I threw it away without looking carefully. Judging from her absent-mindedness, I don't think she can find it either. Then the teacher invited Sun Huilin, a member of our class, to look for it. She found the paper ball that Zhang Leigang dropped, picked it up, opened the paper again, and the coin came out. She held the coin high with excitement, just like a magician. The students below applauded her happily.

It seems very collective wisdom! We must work together and observe carefully. As the saying goes, two heads are better than one, and only by uniting can things be done well.

An interesting class composition 500 words 3 childhood fun is like the stars in the sky, which can't be seen or counted. Today, let me pick the biggest and brightest star and give it to you.

Today, the teacher gave us a lesson in the classroom. The teacher said, "Let's play a game today." Hearing these words, the quiet classroom became active. Do you want to know the name of this game? It's called "draw a nose".

First, Liu Yang came to power, and the teacher told him to close his eyes and turn three times. He turned behind him and the teacher blindfolded him. He walked askew like a crab, but with the help of the teacher, he walked to the blackboard, and the noisy voices of his classmates made him panic. Even I have some sympathy for him. Finally, he drew his nose under his face and made his classmates burst into laughter.

After a while, the teacher found someone else. I didn't expect the teacher to ask me. "Haha, it's time for me to show my talents." I turn left three times and turn right three times. Just after turning the corner, I got dizzy and almost fell down. I walked to the blackboard step by step, ready to draw a nose for this face. When I was about to write, the shouts of my classmates made me extremely nervous, and then the boys shouted "Left! To the left! " The girls shouted: "Yes! Right! " I thought, "Hum! I won't trust boys. Liu Yang was cheated by them just now, or girls are more reliable. " I drew my nose as instructed by the girls. Hey, why is it so strange? It turned out that I drew a nose in the middle of my eyes so that my classmates could laugh with the film, and other students wanted to play behind me. This is really an interesting lesson!

This can tell me that some things seem simple, but it is difficult to do them.

An interesting class composition 500 words 4 Last Friday, Teacher Zhang told us the good news, and the whole class became active. What's the good news? It turns out that Miss Tan Xiao from Beijing is coming to give us a lecture on astronomy.

On Monday, we came to school ecstatic. At noon, a middle-aged man with regular facial features and handsome appearance walked into our classroom. Ah! It's Miss Tan Xiao! At the beginning of the class, we saw Mr. Tan Xiao take out many strange stones from a silver box: some were uneven; Some models are different; Some are small and exquisite.

At first, the teacher picked up a big stone and asked the students to touch it and guess its weight. It happens to be our group. My heart is like dozens of tied rabbits jumping around. When it was my turn, Miss Tan Xiao asked, "Are you nervous?" "nervous!" I said. The teacher touched my hand and took it back. Finally, he put the stone in my hand. I estimated it and said, "1550g." "155 1 gram!" The teacher's voice has improved a lot. I went back to my seat, thinking that the teacher was so loud that my answer should be correct.

Then the teacher told a lot about meteorites. What impressed me the most was the game link. The teacher first asked a question: "which planet is closest to the earth?" Some students in the class sat there motionless with their chins in one hand, as if thinking about the meat just now; Some students stare at the ceiling, as if wondering if their answers are correct; Some students sometimes frown and sometimes lick their lips; Some students tap the table with pens, as if considering the answer to the question ... "Venus!" " "A classmate said." Correct answer! "The teacher shouted with a smile.

This is a course, and it is very hard. It opened my astronomical knowledge and my desire for knowledge of the universe!

An interesting class composition 500 words 5 Today, there is an interesting activity in our class.

First, the teacher writes a word and asks the students to say four words containing it. The teacher first wrote a word "white" on the big screen, and the students raised their hands as soon as they saw it so simple. "white inside is red" and "grow old together" ... you say one, I say one, tit for tat. The teacher wrote another word "day", and many small hands were immediately raised in the classroom. The rising sun, with each passing day, Houyi Shooting Day ... Everyone wants to win more points for their group. Later, we set up idioms for "Yi", "Shan" and "Jin". The students are chirping like sparrows. Say that finish, I glanced at the blackboard, "the mountain covers the day". Ah, so the teacher asked us to write poems.

Digital synthesis begins. The first one is "one", and everyone is scrambling to raise their hands. Lynne volunteered to say "loud and clear" and "single-minded" Cai Xing does not show weakness. He said three things in one breath: in a word, make a clean break, and be serious. Zhang Zhe also blurted out without thinking: "exactly the same" and "kill two birds with one stone". I was deeply impressed and thought: There are so many idioms in their bellies. ...

The most difficult thing is the "sheep" in the Chinese zodiac idioms. Some students frowned and thought hard, some scratched their heads and some held their breath, as if trying to suppress an idiom. Later, the teacher reminded me that it is better to be late than never. The students were enlightened and refreshed from their previous state. Xia Wei came up with these idioms: "a narrow path", "sheep entering the tiger's mouth" and "stealing". Everyone cast an envious look at him.

This course is really interesting. It seems that I climbed to the top of the mountain at once, enriching my knowledge. What a great harvest!

An interesting class composition 500 words 6 Some people like Chinese class, some people like math class, some people like art class ... but I like food class.

This morning, the teacher of Love House gave us a food lesson, the content of which was Bao jiaozi. We put on our kitchen clothes and hats and began to study. Miss Li Jing asked us to stand at the long table and watch her roll the dough. Teacher Li Jing rolls the dough quickly! I saw that she grabbed a small dough and gently pressed it down with her left hand. The small dough became a small round cake. Then her left and right hands work at the same time. The edge of the small round cake in the left hand keeps turning, and the rolling pin in the right hand keeps rolling. Blink of an eye, a dumpling skin was lying on the panel. Gee, this craft is great! I looked envious, so I picked up a rolling pin and rolled the dough as I did. After a while, the dough sticks to the rolling pin like a dog skin plaster. I tried to peel it off by hand, but the dough cracked. Looking at the "injured" dough, I was a little at a loss. Teacher Li Hong next to me patiently taught me the solution. With the help of the teacher, I successfully rolled out a good piece of dough. Look at my work, don't mention how happy I am!

Then I began to listen to the teacher teach Bao jiaozi. See He Laoshi palm up, and then scoop up a spoonful of dumpling stuffing with a spoon and put it in the center of the dumpling skin. Then jiaozi folded in half and skillfully held it with his thumb and forefinger, and a chubby jiaozi appeared before our eyes. I took a spoonful of dumpling stuffing and put it on the dumpling skin like He Laoshi, huh? What happened? Why can't it always be wrapped up? Teacher Wang looked at it and said, "You put too much meat." After hearing this, I put less stuffing. According to this method, after a while, a jiaozi with a "moderate figure" will lie in my palm. "How interesting!" Seeing my food works, I can't help but admire, and my heart is full of joy, just like winning a prize.

This interesting food class, not only let me eat delicious jiaozi, but also let me learn how to pack jiaozi. I like this food class very much!

An interesting class composition 500 words 7 bell rang, and the teacher strode onto the platform. Then he held up a piece of cardboard with a fox on it and asked, "Students, what is painted on it?"

"Fox." Everyone answered with one voice.

"I said it was a demon." The teacher said. After listening to the teacher's words, we all opened our eyes and felt very surprised.

The teacher went on to say, "In rural areas, this phenomenon often happens. Some people go to the witch instead of going to the hospital for treatment when they are sick. Witches lied to him that there was a demon attached to him, so they made some magic tricks to exorcise the demon, burned incense and kowtowed, and asked the gods to bless them. Are there really ghosts and gods in the world? " Some students shook their heads, while others were dubious.

The teacher added, "If you don't believe me, please treat this paper like a fox." We laughed and the picture was clearly a fox. How can we say it is a demon? How interesting!

The teacher said solemnly, "well, now I'll kill the demon for you!" " "I saw the teacher take out a kitchen knife from a basin full of water and cut it at the fox's neck. Suddenly, the fox was really "stained" with DC.

"Students, do you know why this is happening?" The teacher asked. "Probably the color of the fox has faded." "What else?" There was silence in the classroom and everyone frowned.

"I'll tell you." The teacher explained: "My basin of water is not an ordinary basin of water, but an alkaline basin of water. I sprinkled some phenolphthalein on the fox in advance, and the combination of alkaline water and phenolphthalein will turn red. This is called a chemical reaction. You will know this knowledge when you go to junior high school. " Hearing this, the students suddenly realized.

Finally, the teacher told everyone: "there are many phenomena in nature that people can't explain yet." So some people with ulterior motives fabricate ghosts and gods to scare people. Witches use people's weaknesses to deceive people who don't understand science. Therefore, we must study hard scientific and cultural knowledge, believe in science and get rid of superstition. "

This is really an interesting thinking class!

An interesting class composition 500 words 8 Today, there will be an exciting game in the composition class-drawing the nose.

The teacher drew a face on the blackboard. It is strange that there are eyes and mouth on the face, but no nose. Just as we were wondering one by one, the teacher said, "The name of this game is to draw a nose. The rule is to cover your eyes with a towel first After three turns in the same place, you go to the podium and draw a nose on your face with chalk. Draw the right position to win. " Students are eager to try, one by one scrambling to raise their hands and shout: "I'll come first, I'll come first."

The first student to draw a nose is Feng Yier. She was blindfolded, turned three times, stumbled onto the platform, picked up chalk and drew on the blackboard. Before she finished painting, the students were already laughing their heads off. She hesitated and drew in another place. Just drew a pen, the students laughed more happily, and there were female students who made people rub their stomachs; Some male students patted the table and stool with a smile; Feng Yier knew that the painting was wrong again, so he simply did nothing and changed his position ... This time, some students simply slipped under the table with a smile. Ha ha! Feng Yier drew a face with five noses! Some grow on the forehead, some on the eyebrows, some on the eyes, and some even on the neck, but none in the middle of the face! Finally, even after reading her own work, she couldn't help blushing.

The second student who draws a nose is Wu. He groped his way onto the platform and almost tripped over a dog. He picked up the chalk and drew confidently. Looks confident. Just after painting, warm applause sounded. He is the first person to draw correctly.

The last classmate who drew a nose was me. I picked up the chalk and my heart was pounding. I carefully walked onto the platform and thought: Come on! Come on! Be sure to draw it correctly. After painting, the students swayed from side to side and laughed earth-shattering. I quickly took down the towel and looked at it, only to know that I had painted my nose on my mouth!

Happy times always fly by. I am really happy in this class!

An interesting class composition of 500 words 9 This afternoon, the teacher gave us an interesting lesson. The game for class and team class is 123 Woodenhead. The rule is that the teacher can't move or laugh after turning his head. Whoever moves and laughs will lose, and whoever touches the teacher's back first will win. The teacher divided us into two teams. One team told us never to laugh, and the other team told us to laugh in our hearts and not in our faces.

The game has begun. After the teacher said "start", some students took a few steps forward, some stayed where they were, some were lying on the table, some were sitting in chairs ... We waited like cheetahs to touch the teacher's back. Seeing that we were neither moving nor laughing, the teacher came up with a clever plan. Then, she kept telling jokes and laughing. After laughing for a few minutes, someone in the team finally couldn't help laughing. Therefore, the team that didn't laugh to death lost because of this classmate's inattention.

What I like best is the third game of this game, because the teacher also sent the players who were eliminated in the first two games to make us laugh. They laugh in other people's ears for a while, and blow in front of others for a while ... that posture seems to be playing a monkey. However, the deceived team was very determined and tacitly took a smoke screen to hold back their laughter. Finally, until the bell rang, they didn't tease anyone to succeed, so they had to go back to their seats angrily. At the same time, there was an earth-shattering laugh in the classroom. After waiting for so long, I can finally laugh.

Ah! What an interesting lesson! I hope the teacher can give us a lesson every week, because it can not only increase our knowledge, but also relieve the pressure of study and make us enjoy school life more.

An interesting class composition of 500 words 10 came into the classroom today, and there was a burst of music. The melody of that music is so beautiful and the lyrics are so familiar. We listened with rapt attention. Listen carefully, even Xiao Gang, the "naughty king" in our class, is quiet. Later, we listened carefully and found that the teacher was playing Descendants of the Dragon. Accompanied by singing, the teacher told us that today we should visit the dragon paradise, learn about the dragon, feel the dragon and feel the infinite charm of China traditional culture!

The game has begun. The first round was Lianliankan, and the teacher asked each group to choose a representative to "play". I am the representative of our team, and the representative of zero one is Xiaohong. When the teacher asked me to take the stage to make a two-part allegorical saying, I linked "the Longmen array is short of people-it can't stand up" with "arrogance". "Well, I refuse to accept it," I said. The teacher said, "If you don't accept it, you have to refuel next time!" " "In the end, I made two mistakes, and Xiaohong also made two mistakes. We are even.

The second round has already started, which means dragon idiom. Make the finishing point, Yes, Ye Gong loves dragons and …………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………… The classroom was in chaos. "Quiet!" The teacher's "long whistle" finally made the classroom quiet. Finally, our group won.

The game continues, and the excitement continues. In the game, some people perform "tornado" like dancing; Some people perform "Dragon Boat Race" back and forth like desperate Saburo; There are also people who can't perform anything like geese. A performance brought us bursts of laughter.

This course is really interesting. Not only makes us feel happy, but also lets us know a lot about dragons, and makes us proud that we are descendants of dragons. I love the mythical dragon. Love our people in China even more.

An interesting class composition of 500 words 1 1 As a real Tongxiang person, I can't speak the local dialect, which makes me a little ashamed.

A few days ago, my mother took me to the "dialect school" in the community.

At first, the teacher ordered a song we are most familiar with, and everyone enthusiastically sang along (Mandarin). Then, the teacher showed us a table with the addresses of family members in dialect. She pointed to the blackboard and said, "Look, children, this is a personal relationship sheet. Who can speak in dialect? " A boy raised his hand high and slowly blushed and said, "Grandma is an empress, my sister is big, and my grandfather is big ..." "That's right." The teacher praised, "these are relatively simple and can't beat you." Next, let's learn something more difficult. " The teacher smiled and pointed to the words "egg soup" and said, "The eggs are hot." Xu Zhixin, look at it. Because my heart is weak, I am afraid that my strange pronunciation will lead to laughter, so I gently squeeze out a sentence: "My eggs are hot." Sure enough, several students next to him burst into laughter.

The teacher said seriously, "Don't laugh. Mandarin can make you go a long way, but dialects can teach you not to forget your starting point; Mandarin makes you communicate smoothly, while dialects can make you feel infinite warmth. "

The teacher called several students, and everyone's pronunciation was not very standard. Learn a word and the classroom will "boil" once. The teacher also smiled and said, "It seems that there are still many students who can't speak. Let's read it and play it together-White Elephant, Time-Guang Chen ... "We are so devoted to our study that it seems to open a new door!

Following the dialect, the teacher took us back to our childhood and relived the game of "grasping the week".

When I got home, I shouted at my father, "I want to go to the white elephant in the Ming Dynasty!" " "Dad was surprised and asked me where I learned it." Hey, I can't believe it. I participated in dialect activities today. Of course the teacher taught me! "I smiled triumphantly.

Dialect records the local customs and describes the etiquette and custom culture of each place. I feel the fun, and I will try to use dialects in my future life.

I had a very interesting class today.

The teacher taught us a lot of new knowledge in class, which gave me a new understanding of Chinese. In the past, in Chinese class, the teacher only talked about the meaning of paragraphs and words in the text. I always thought that there were only a few things in Chinese, so I just had to copy them back, but after taking Teacher Le's class, I changed my mind-it turned out that Chinese can also have so much knowledge.

In class, Mr. Le talked about a lot of new knowledge: for example, the central idea of the article was created to make people understand the truth of being a man; Reading a composition with emotion can make you taste it more deeply and understand it more easily. Skills in reading during the exam can be accumulated as usual; Writing is not to be talented, but to have feelings and feelings.

I also learned a lot in class. Teacher Le put it well: "Learning Chinese is learning to be a man." We should learn to label our mood and life with different attitudes, which is the way to produce one hundred and eight generals. We should learn to feel life, and then we can feel it. We want to be giants of ideas, and this is our aspiration. Being a good teacher and a good friend is closely related to Chinese.

The first time I met General 108 was in this class. They are divided into emotion and reason. They have many names: life, beauty, happiness, health, tolerance, respect, mentality, habits ... Each card is a story, and each card represents an emotion, which guides us to write our composition and feelings. Grandpa Ba Jin put it well: "I write not because I am talented, but because I have feelings ..." Only by using feelings correctly can I go further and further on the road of composition.

This interesting class made me know Chinese again. It lets me know that only "feeling" will lead you to the right path of literature.

An interesting class composition 500 words 13 Since school, we have listened to many interesting and vivid classes, but the most unforgettable one is a math class.

That day, the math teacher Liang came into the classroom with a lesson plan in his hand, and the chirping voice in the classroom stopped immediately. Teacher Liang said to us, "Students, today we are going to learn Unit 5-Tree Planting. Please turn to page 73. " Everyone immediately took out their math books and only heard the sound of "brushing" books in the classroom. The teacher said, "Now please solve the first problem first." After a while, Liu, a student on duty, raised his hand. The teacher said: "Liu, tell me, a 600-meter-long road, plant a tree every 15 meters, and plant both ends." How many trees can you plant? " Liu said, "You can plant 40 trees." Teacher Liang said loudly, "Please draw a picture on the paper." After a while, Liu said, "Teacher Liang, no, it should be 4 1 tree." Teacher Liang said with a smile: "Yes, today we are going to talk about the truth of' make a clean break and add one'. Now, please discuss it in your group and see if you can come up with other ideas to solve the problem of planting trees. "

After intense discussion, our group sorted out three ideas: 1, in the case of no planting at both ends, the tree is equal to the number of segments MINUS1; 2. When only one end is planted, the tree is equal to the number of segments; 3. Plant both ends, and the tree is equal to the number of segments plus 1. Just then, Teacher Liang gave an order: "Ok, stop!" The students in the front row turned their heads and looked at Mr. Liang with all eyes. Teacher Liang said, "Who wants to write the ideas summarized by your group on the blackboard?" Everyone scrambled to raise their right hands. Teacher Liang ordered Wu Yong, the leader of our group. Wu Yongsang quickly wrote down the discussion results of our group on the blackboard. Teacher Liang said, "Well written. Please copy these three laws into your textbook. " At this time, a classmate spoke: "Teacher Liang, how can a tree be equal to a broken number?" When we saw it, it was really the word "broken", and the classroom burst into laughter.

Jingle bells, Jingle bells ... The bell is ringing, and class is over. This is really an unforgettable math class!

An interesting class composition 500 words 14 The first class in the afternoon is science class. Last class, Teacher Wang told us to do experiments in the next class. Out of the desire to do experiments, I returned to the classroom early before the bell rang.

"Ding", finally got the lesson. One by one, the students returned to the classroom to prepare for class. After a while, Miss Wang came and saw a big green basket in her hand. The students talked excitedly at once. Finally, the classroom was quiet, and Miss Wang gave each of us a small box in the basket. I couldn't wait to open it and found some red and blue iron blocks in it. The teacher asked, "Does anyone know what the iron in the box is?" The students were silent. After a long time, one of them finally stood up and said, "This is a magnet." Oh, so this iron block is called a magnet! The other students suddenly realized. Teacher Wang showed us an illustration in the textbook, which painted a train suspended on the tracks and told us what Yue had found. The answer of most students is that this train can fly. Teacher Wang shook his head and said, "This train doesn't fly. It uses the principle that magnets attract like and attract like.". I asked doubtfully, "Teacher, what is' like-sex repulsion, opposite-sex attraction'? "Teacher Wang told us:" Like-poles repel each other, that is, putting the same poles of magnets together will produce mutual repulsion; "Different magnetic poles attract each other, that is, putting different magnetic poles of a magnet together will produce attractive forces."

Then the teacher asked us to verify. I can't wait to stick the red end of one magnet to the iron blue end of another magnet. Suddenly, like a pair of invisible big hands, I squeezed the two magnets tightly together. I put the red poles of the two magnets together again. Strangely, there is an insurmountable deep current between them, but they just refuse to attract each other. Close them forcibly, and as soon as the hand is released, they will bounce off immediately.

It turns out that magnets are so magical that they are inseparable when they meet the opposite sex; Meet the same sex, but stay away. There are countless anecdotes in the scientific community that I didn't know before. "The road is long, Xiu Yuan, and I will go up and down."

An interesting class composition 500 words 15 In today's composition class, the teacher mysteriously stepped onto the platform with a schoolbag in his hand and said to us, "Today we are going to do an experiment to make quail eggs float in the water. The students watched curiously while the teacher was doing the experiment.

I saw the teacher take out a quail egg, a plastic transparent cup, a chopstick, a small spoon and a bag of salt from the bag.

The experiment began. The teacher first drank half of a glass of water, and then put the quail eggs in the cup, only to see the quail eggs slowly sink to the end. Then, the teacher said to the students, "Look, everyone, I want to make quail eggs float on the water." My classmates and I looked at each other with a dubious look. The teacher didn't say much, so he dug a spoonful of salt with a small spoon and put it in the cup. He stirred it with chopsticks, but the quail eggs did not move. The teacher put another spoonful of salt and stirred it, but the quail eggs were still lying at the bottom of the water and refused to come up anyway. I am really worried that the experiment will fail and quail eggs will not float. Later, I saw the teacher add salt and stir again and again, and the miracle finally appeared-quail eggs really floated on the water!

After the experiment, the teacher told us why quail eggs floated. The teacher said that water is buoyant, so when we swim, we will feel our bodies floating involuntarily. Quail eggs began to sink to the bottom because quail eggs were heavy and the buoyancy of water was small; Adding salt to water can increase buoyancy, so quail eggs can float.

Today, this interesting composition class not only taught me to write a composition, but also taught me a little scientific knowledge. What a great harvest!
