"Qi" is a polysemous word. The Oracle Bone Inscriptions-shaped "open" is like opening a door by hand, so its original intention is to open it. The following is my composition about the third unit of the fourth grade Chinese book, welcome to refer to it!

Early in the morning, I found a spider web in the corner of my house, and my strong curiosity drove me to catch a small grasshopper and put it on the spider web.

At this moment, a spider crawled out from the crack in the wall. It vomited a mouthful of white silk next to the grasshopper, wrapped it up and returned to the hole. I am puzzled: why do spiders go back to their holes and why don't they eat grasshoppers? I continued to observe. But after waiting for a long time, the spider just won't come out.

The next day, I was surprised to find that the spider had eaten the grasshopper, leaving only an empty shell on the Internet. I wonder why spiders don't eat shells. In order to find the answer, I read a lot of information and finally found the answer in "100,000 Why". It turns out that after a spider catches its prey, it first wraps it with silk, and then spits out a digestive juice and injects it into its prey. This digestive juice can dissolve the internal tissues of insects composed of protein, and it will become juice after the insects die. Spiders can suck big mouthfuls. Because the shells of insects are not made of protein, the shells of grasshoppers remain intact on the net.

Through this unexpected discovery, I know the mystery of spiders eating. Although this is only a small discovery, it makes me understand a truth: pay attention to learning everywhere. It seems that the essence of Pingla Fanfan actually has endless mysteries waiting for us to explore and discover.

I am proud of my little discovery.

Unit 3, Volume 2, Grade Four Chinese Composition 2 After the rain cleared, a beautiful rainbow appeared on the horizon. I ran out of the house happily to see the beautiful rainbow after the rain. Walking, I came to the tree. The crystal beads of rain on the leaves, as well as a string of dripping rain, make a "tick-tock, tick-tock" sound, which is really nice to listen to, like a beating note.

Suddenly a crawling creature crawled slowly in front of my eyes. What is that? Curiosity drove me to find the answer. I squatted down and saw that it was a small snail, but it climbed so slowly. What can it do?

At this moment, my father stood beside me. He seemed to read my mind and said, "Although climbing is so slow, it is very useful. It can be used as medicine to treat diseases. " Moreover, the snail's shell is very hard, which can supplement calcium and protect the body from other animals. What can you think of to protect yourself from this? "

After listening to my father's words, my thinking accelerated instantly: mom and dad can protect me, but mom and dad also need protection. Of course, it is home that has been protecting us. Thinking of this, I said to my father, "It's a house. It turns out that our human house is inspired by snails! " "After listening to my words, my father said," That's right. The house can shelter us from the wind and rain and live a happy life, so home is a warm harbor in everyone's heart. "

Through today's observation, I finally understand that some unremarkable things can often give people a lot of inspiration. If you use your head and observe carefully, you will find more mysteries of nature.

I see a spider in the wind.

It hangs on a thin spider silk hanging from the door frame, just like a safety belt, tied around the climber's waist. The wind blew on her cheek, blowing the spider desperately, as if she had any enmity with the spider. The spider clung to the "seat belt" with its eight legs, trying to find another foothold while keeping itself from being blown away by the wind. It shook violently in the wind, and the wind couldn't wait to throw it out without giving the spider a chance to breathe. When the wind stopped temporarily, the spider stretched its silk to prepare for the next baptism of the wind.

There is a pool not far from the spider. That pool is nothing to us, but to spiders, it is a sea of Wang Yang. Spiders won't miss it. Besides, the wind is so strong that if you are not careful, you will be blown into the "Wang Yang Sea" and drowned. Then why does it persist in the wind? It is for the dream in its heart-a huge spider web!

After a summer rain, I saw a huge net in Hongmei Park. Spider webs are among several trees, bigger than me. The silk wound around and expanded from the inside out, hitting my heart like that violent shock wave. The net sparkled in the sunset. All this turned out to be the masterpiece of a long-legged spider. It sits in the center of the net and tastes the joy of success.

Looking at this spider struggling in the wind, I understand what "adventure" and "struggle" are.

A cartoon, a motto, and everything will inspire you. My inspiration comes from some things I have experienced.

I remember once, my parents and I climbed incense burner peak together. We put on sports clothes, sports shoes and water, and headed for Lu Xiangfeng. As soon as I arrived at my destination, I rushed out first. Xianglu Peak is 354 meters above sea level, with steps 1508. There is a rest platform of almost two square meters every other step, and there are three pavilions in the long step queue for people to rest. At first I climbed fast, but after three minutes, I slowed down. Gradually, I feel more and more tired, and my feet seem to be tied with lead, so I can't walk. Go to the third place, finally see the pavilion, finally can sit down and have a good rest.

In the pavilion, sitting next to me is a little girl who looks much younger than me. I learned from talking with her that she is three years younger than me and is next to her white-haired grandmother. The purpose of climbing incense burner peak this time is to pray for her grandmother and make her healthy. I saw grandma laughing from ear to ear when she heard what she said. I think her grandmother must be saying in her heart, "I climb incense burner peak to pray, and I hope my granddaughter is healthy and smart."

After a short rest, we continued to set out, and the little girl and grandmother also started. Similarly, after walking for a few minutes, I began to feel tired and unable to walk. I turned to see the little girl's head was full of sweat, but her eyes were firm. Although grandma is holding the railing, she is full of air. I thought, "I will try my best to climb up like them." I made up my mind, finished sweating and tried to walk to the top of the mountain. I hurried forward, and I cheered in my heart: "As long as you work hard, the iron pestle will be ground into a needle."

After some efforts, although I stopped and walked, my clothes were soaked with sweat and my feet were about to grind and bleed, I still stubbornly climbed to the top of the mountain. Along the way, I saw strange rocks such as Half Moon Rock, Yunmen Rock, a rock, and Flystone, as well as Rat Tower and Qianzhangkeng. The top of the mountain is foggy and the scenery is beautiful.

At the top of the mountain, I saw the little girl and her grandmother again. I really want to thank this little girl, who taught me "persistence is victory" and "where there is a will, there is a way".

Fourth grade Chinese book Unit 3 Composition 5 Small Numbers, Great Truth! What do you think of the decimal number 0.0 1? Isn't it just a decimal close to 0? In today's class, Mr. Jiang made us understand the life truth of 0.0 1.

First, Teacher Jiang asked a math question: "How much is 1 multiplied by 365?" This question is obviously not difficult for everyone "1" to answer in unison. After that, Teacher Jiang gave us a duel: "What is (1+0.0 1) multiplied by 365?" The class suddenly exploded the pot, but it seemed a bit difficult, and everyone racked their brains to remember it. Most people think it is 1, but it is actually wrong. What the hell is that? We are all puzzled. Teacher Jiang wrote 38 on the blackboard. "38? !" The students all exclaimed, "Strange, is a small 0.0 1 really so powerful?" But that's the truth. Then Teacher Jiang asked us, (1-0.01) how much is 365 months? Although difficult, it was also calculated as 0 by Zhu Xingjian. Everyone was shocked again.

Yes, a small 0.0 1 does have such a great power, and 365 is equivalent to one year. The first formula means that if you don't make progress for one year, you will still be at the original point after one year. As long as you make a little progress every day, every little makes a mickle, and you will get extra gains in one year. The third formula tells us that "sailing against the current, if you don't advance, you will retreat." When others are trying, you are regressing. As a result, you will get nothing after one year. Even Emperor Liu Bei once said to his son, "Don't do it because of good, and don't do it because of evil." So do some celebrities. Although Charlotte was not well educated, she gradually enriched her knowledge with daily accumulation and eventually became a world-famous female writer. On the contrary, her talented brother was too proud to study, slowly regressed, and finally gave up on himself and died at the age of 39.

I remember that when I was a senior one and a senior two, my study was very poor. Others scored 100 easily, while I was only seventy or eighty. I was often criticized by my teacher, but I didn't give up. I insisted on doing exercises every day, and my grades improved greatly after half a year. However, the recent Chinese mid-term survey only scored 97 points, which made me a little depressed. But when I saw: "(1+0.0 1)365 is about 38, I was open-minded and cheerful again. There is a good saying, "You can't take ten steps in one leap, but you can't give up your efforts. "I think as long as I continue to work hard now, I will do well in the exam and make greater progress.

"If you don't accumulate steps, if you don't accumulate steps, it is difficult to become a river." Life lies in accumulation. As long as you work 0.0 1 more than others every day, you will get extra gains after one year and your life will be more exciting!

The fourth grade Chinese book Unit 3 Composition 6 I watched Lu Xun's Kite again a few days ago, and my thoughts flew to my childhood memories with this kite.

When I was a child, my parents would always take me to the square every spring, buy a beautiful kite from the old kite seller, and then let it fly high in the wind. My heart followed the kite and flew high with the wind.

I remember it was windy that day, and there were a few simple and honest clouds floating in the sky. There is a big and thick cloud hanging on the horizon, and the sun shines on the cheeks of the big cloud, like a naive smiling face of a real child, and like a big castle full of happiness and happiness. As usual, I am flying in the sky with a brand-new kite and want to fly to the carefree castle. I hold the kite string in my hand, and the more I let it go, the swishing the string flies outward, and my heart flies higher and higher with the kite. Suddenly, the thread suddenly tightened and loosened, and the kite was relieved and plunged into the "castle" and disappeared. The thread I held in my hand became empty because of the loss of the kite, and my heart was extremely lost.

At that time, I felt so unlucky that I lost my beloved kite that my heart could no longer fly with it.

Now, I feel lucky. Although I lost a kite, I learned two things.

Whether in life or in study, we should stop at the same place and finish what we started. You can't do things without beginning and end, it will only be counterproductive. Study is very good, but study is very hard, forget to eat and sleep, sleep and eat; What is about to happen will cast a shadow in front of them, which is a precursor of good things turning into bad things and will affect their physical and mental health.

Everyone has his own dreams and ideals; To realize dreams and ideals, we must stick to it.

One afternoon, my family came to Dongshan Park to play. As soon as we arrived at Dongshan Park, my brother and I went straight to the fish pond.

Without waiting for my mother to pay, my brother and I grabbed the fishing rod and bait from the boss and prepared to go fishing. First, I put the bait on the hook, then I lifted the fishing rod and threw the fishing line.

After a while, through the clear water, I saw a black and white fish hooked. I am so excited! I put it away carefully and manipulated it skillfully. Maybe the fish wants to get rid of my hook. When my hand slipped, the fish easily got rid of my hook. The goldfish swung vigorously and disappeared in the blink of an eye. At this time, my brother has caught a beautiful goldfish, and I am in a hurry. My brother is five years younger than me. He caught a fish. How humiliating I am as a sister!

I went on fishing. At first, I complained that I didn't hold the fishing rod tightly. Later, I complained that I was standing in a bad position. So I changed my position, and later I changed my position, but no matter where I stood, I still found nothing.

"Those two children, it's time." The boss shouted. I saw my brother catch two fish, and then looked at my basin. It was empty. I really want to find a gap to get in!

From this fishing incident, I understand that you must be patient and stick to it, otherwise you will accomplish nothing.

During the winter vacation, the snow was so heavy that the whole city was covered with snow. It was so beautiful. But in this beautiful scenery, the city is in trouble, the cars on the road are slow and pedestrians are cautious.

On TV, in the newspaper. How many people died and how many people were injured because of this snow. Although we can't control nature, human beings have firm confidence and courage to challenge nature.

On this day, I was with many friends, holding shovels and brooms, ready to clear the snow in our yard. For me, it is not the first time to see snow, but it is the first time to shovel snow. I just picked up the shovel and felt curious. I held the upper end of the shovel and shoveled the snow hard. I thought the snow was light, so I put the shovel deep, but when I pulled it up, I found that the snow was not light at all. Can only shovel snow bit by bit.

At this time, in our yard, in addition to birds singing, there are sonatas of shovels and the ground, "Ping Ping, Bang Bang", which is very lively. Gradually, the body gets hot, and of course, the motivation is even greater. Soon, a large piece of snow was shoveled away by us, and we were so happy. Although it is only a small victory, it is hard for us!

After shoveling the snow, we are very tired and can't wait to go home and rest in that soft bed, but this is not what I think of at the moment.

I think if everyone shovels a little snow, are humans still afraid of this natural disaster? If everyone is careful, will there be a tragedy in this heavy snow? One person's strength is small, but everyone's strength is great. As long as people unite as one, why should they be afraid of the so-called snow devil?

Through this incident, I have a deeper understanding of the meaning of "many hands make light work", just like the story of folding chopsticks. As long as everyone is Qi Xin, what difficulties can't be solved?

Unit 3 Composition 9 of the Chinese Book in the second volume of the fourth grade will not only tell us enlightenment, but also tell us the truth with just a few lines of cartoons.

Hua's cartoons will give us a lot of inspiration, such as "Pseudoilliteracy". In the cold winter, a mother held her child and looked at four middle-aged people. It turned out that these middle-aged people stood in the "mother-and-baby boarding house". Are they illiterate? But judging from their clothes, they don't look illiterate. The first middle-aged man was wearing a green coat, smoking a cigarette and wearing blue trousers. The second middle-aged man is wearing a green coat, a green hat and black leather shoes. The third middle-aged man looks very well dressed, and none of them seems to be illiterate. The mother who has been holding the baby for several months has been staring at the four "fake letters". The first middle-aged man smoked a cigarette casually; The second middle-aged man has a calm eye and doesn't feel that he has done anything wrong; In the mother's eyes, the third middle-aged man is not illiterate, but blind.

There are also many examples in our life, such as a strong man seeing a "female seat". Instead, I pretended not to see it and sat directly. Obviously, smoking is not allowed in the car. Regardless of other people's feelings, he turned on the lighter, lit the cigarette and started smoking. In the park, a boy fed chocolate to a bird. The boy clearly knows that birds can't eat chocolate unless they feed it to them. In a park, there was a sign that said "No littering", but a week passed and the sign was flooded with rubbish.

In our life, illiteracy is not advocated, and fake illiteracy is even more shameful. They undermine public order and public health. False illiteracy is not illiteracy, but embarrassment.

Unit 3 Composition 10 Ants are United and friendly, and people can learn a lot from them. Nature not only inspired people, but also discovered the ultrasonic wave of bats and invented radar. People found that geckos can crawl around against the wall, which seems very common, but they invented special materials. People found that water dripped on the spider web, and the web would not break, so they invented a new type of body armor, all inspired by nature.

What inspired me the most was the insignificant ants. They fight alone and can almost be killed in one blow, but their unity should not be underestimated. They are much smaller than bees, but they are more United and hardworking than bees. As soon as they predict that it will rain, they will move to high places and remove the sand one by one. They will not give up halfway, will not give up halfway, and will not stop because of anything. Even if the invaders come to grab the territory, they will not stop.

If they need food, they will send a small number of ant soldiers to find it. If one of them finds food, it will immediately move back to its nest to share it with its companions. If the food is too big and too heavy to move, the ants will inform their companions and send an "army" to move the food. If the "army" can't move, it can only eat immediately, otherwise it will attract some "rice bowls".

If there is a "grain thief" in the nest, the ants will send a small group of workers to attack, and never attack alone. One by one, the ant soldiers showed no mercy to the enemy until they were wiped out.

Their spirit has benefited me a lot in my life, and let me know that unity is the best communication between people.

The fourth grade Chinese book Unit 3 Composition 1 1 The sky is gray, like a monster taking away the blue, leaving a melancholy gray, which makes people fidgety. Rain is still falling, dripping into my heart, and the raindrops are thought-provoking.

I sat alone on the silent balcony, listening to this natural and beautiful symphony. Watching the dripping raindrops reminds me of the growth of raindrops. At first, it swam around in streams, rivers and the sea, but because of its efforts, it came into contact with the sun, which shone on the water all day, and then the water turned into steam, persistently flew into the sky, flew in a cloud boat, and finally became rain that could drop into people's hearts. All its efforts, all its self-motivation, are aimed at persisting in the dream of becoming raindrops. I think every drop of water will have its own goal.

"If you were a drop of water, would you moisten an inch of land? If you are a ray of sunshine, do you light up a little darkness? "

Rain is also enlightening us. If you are a student, do you make knowledge shine? If you are a student, do you stick to your ideals? If you are a student, are you fully prepared for your tomorrow? "Opportunities are reserved for those who are prepared." Water is preparing for its own tomorrow, except for the bright sunshine. Are you ready to look for that opportunity?

Chinese Unit 3 12 in the second volume of the fourth grade "From a person's ability to handle affairs, you can see the knowledge level of a day. But the good and evil in his heart must not be speculated, because it will take a long time to see the pros and cons in his heart. " This is Sadie's famous saying, which has been deeply engraved in my mind and has become a wake-up call for me to know new things in the future.

Not long ago, I made a new friend. I can never say his name here. The first time I met her, I found that her knowledge was quite "profound" and she looked very gentle. I have great respect for him and sometimes even praise him. He and I are like "wearing a pair of pants". My relationship with him has long exceeded my relationship with my old friends. My friends began to be jealous of us, but I didn't realize that because I was with new friends all day, my old friends and I had less and less contact with them, so I didn't know when the disaster happened. Looking back now, I understand another truth: if a person does not create new knowledge in life, he will soon find himself lonely.

After getting to know this friend for a while, I found that she always likes to speak ill of others in front of me, and I began to alienate him gradually. At the same time, I also understand the true meaning of another sentence: don't make irresponsible remarks behind others' backs, so as not to be regarded as a rumor monger by others, because not speaking will not hurt people, and making irresponsible remarks will get you into trouble. Friendship and words often mask self-interest, so you should be very careful in choosing friends. Therefore, we should strictly follow a famous saying of Valloward: "You should give a pure person a bad friend."

I remember five years ago, my parents bought me a "Golden Cup" accordion for more than 3,000 yuan. I was so happy at that time that I made up my mind to practice the piano well. After finishing my homework every day, the first thing I do is to read the music carefully, practice the simplest fingering and play the accordion. After a while, I can play simple music. What a sense of accomplishment Later, I easily got the first and second accordion exam certificates. Oh! It turns out that playing the accordion has both bitterness and joy.

This year, the accordion teacher asked me to take CET-6 directly. In the summer vacation, I took the five-level qualification examination first, and then took the six-level music theory examination after passing the examination. Today is the last level of CET-6. Early in the morning, I couldn't sleep any more. I quickly went to the study to pick up the piano and wanted to cram for the last minute. Pulling it to an unskilled place, I was so anxious that I couldn't help sweating from my forehead. I regret it very much

The teacher called my admission ticket number. Ah! It's my turn! With the help of my mother, I put the piano on my back, took the admission ticket and looked at my mother. She looked at me with expectant eyes, full of love and expectation. Suddenly my confidence doubled and I stepped into the examination room. There are two judges and teachers in the examination room. They all looked at me with a smile. I sat in a chair, and when I heard the instructions, my fingers were so nervous that I couldn't even find the sound, and my palms were sweating. At this time, the judge and teacher spoke: "Don't worry, son, take your time!" " "I closed my eyes, took a deep breath, and my mother's encouraging eyes came to my mind. I found the first sound at once, my fingers danced quickly on the keys, and beautiful music flowed from my fingers. I successfully played the second song "Harvest Song" before I knew it. Don't you remember the second half? Skilled, just when I was worried about making a fool of myself in the second half, the judge teacher waved me to stop.

This is an ironic cartoon, depicting a wood thief with an axe in a lush forest, waving an axe and chanting "There must be bugs in this wood." A woodpecker stood on his shoulder and looked at his wooden head angrily.

Many people like to cut down trees and make all kinds of things to sell. If you cut down a tree and plant a tree, it can serve us forever. If you cut down a tree instead of planting a tree, then you only have these trees. These trees will not increase, but will only decrease rapidly. Not only that, but also smoking. Smoking not only poses a threat to your body, but also has an impact on the air in nature.

There is a woodpecker with an axe on his shoulder. This woodpecker knows how to take care of and defend his home.

We humans should protect our homes, and at the same time, we should prevent others from destroying our homes.

When I was a child, I liked dandelions in the wild.

In early spring, it raises yellow flowers and stretches hard, even if it encounters one or two cold rains and snows, it does not shrink back; As long as you are touched by the sun again, you will be happy soon. On the sparse grassland or roadside in the countryside, its round and bright smile is really the most natural dedication in early spring. Its requirements are very low, it can survive in almost any soil, it is not afraid of trampling, its flowers are integrated, its petals will not fall off and will not be destroyed. Its smile is eternal, and it is the most common feeling of spring that is bound to come after winter.

And the seed of its plush ball came to this world in a hurry. As soon as the breeze passes, they float in the air like umbrellas, then fall into any soil and start new breeding.

And these fluffy umbrellas are children's playthings in spring. Put it in your mouth and blow it gently, and all the white flowers will fly into the air like parachutes, which can arouse people's interest and fantasy about virginity more than blowing soap bubbles.

When I came to America in April, I was even more delighted with the yellow flowers all over the lawn. I think it would be disappointing if there was only endless green on the lawn in spring without yellow dandelions. So I often stop by the roadside and the house and watch it greet my distant guests with a smile.

It's a pity that I am too romantic to feel life from the perspective of poetry. It turns out that the owner of the homestead doesn't like this yellow flower. They often pull out dandelions when cleaning the lawn because they are too tenacious and grow too crazy. If allowed to spread, dandelion will devour this neat lawn. Moreover, they grow irregularly. When they grow up, they will be wild and occupy a lot of territory.

God, this spring smile is actually an ugly object to be eliminated!

But what can be done? Who can let it grow quietly, only constitute the ornament on the lawn, not crazy, not flooding, not bullying the sister grass?

I think this should be that kind of "degree"! Everything in the world has a degree and needs natural balance. After the "degree", beauty becomes ugly, and after the "degree", love may become disgust.

Freedom can only show beauty, chic and respect in "degree".

And do our manners, speech, habits, communication, even friendship, love and family all have a "degree"? Do we also need a "degree"? How can we learn to master this "degree"?

Dear friends, let's experience, feel and practice in life!

The composition of Unit 3 of Chinese in the second volume of the fourth grade 16 is cool, which brings not only coolness, but also the joy of harvest.

I walked in the shade of a tree, and it was surprisingly quiet around me. No idle footsteps, no tall figure, no smooth conversation, and no. Only, leaves like yellow stamps are falling alone, which is a special and inexplicable sound.

Flowers bloom and fall. I don't know how many spring, summer, autumn and winter have passed, nor how many leaves have fallen in Qian Qian. Today, it is autumn again. Autumn is an unusual season. A flying autumn leaf is her symbol. She doesn't have the flowers and birds in spring, the hot sun in summer, the thousands of miles of ice in winter and the snow in Wan Li.

She is Qiu. Autumn is called "fall" in English, which means falling. Yes, but have we ever remembered that not only the bleak autumn wind embraces the earth with the fallen leaves, but also many golden fruits fall with the fallen leaves and gradually enter thousands of households.

Ah, what kind of experience? Two years ago in the summer, I came to the countryside, and a golden field came into view, like a familiar and strange friend, and like a bosom friend after a long separation. Walking into the field, my nose seemed to smell an attractive fragrance. I was surprised to find that the rice hidden inside became more and more golden, and I bent down slightly, as if to pay tribute to mankind.

Looking around, there are many farmers fertilizing crops not far away. On a sunny day, the farmer's uncle wore a homemade straw hat, a T-shirt, round trousers and sandals under his feet. A very difficult expression appeared before my eyes. They sweat like rain, dripping into the ground like soybeans. Originally polished face, now it has been flushed by the scorching sun. They work tirelessly, although they are not destined to work under the service of air conditioning like white-collar workers in enterprises, but they have no complaints. In order to have a good harvest in the autumn season, present the most delicious fruit to everyone.

Sad but sweet. After the passage of time, erase the traces of the past. Another autumn has arrived. I went to the wild again.

Or farmers. Bend down as usual. They seem to be busier, busy harvesting, busy autumn, avoiding the summer sunshine, although the warm autumn wind blows across the farmers' faces. They work hard and get presents again and again in autumn. Their dedication needs no expression.

In the countryside, they are as simple as dirt, and in the city, they are also drowned in the noisy crowd. Their silent and selfless attitude touched me.

The picture is fixed in front of you. Want to cry, I raised my eyes, trying not to let tears flow out.

;
