Explanatory composition
In our daily life, everyone will inevitably come into contact with composition. According to the different writing time limit, composition can be divided into limited composition and unlimited composition. What kind of composition can be called an excellent composition? The following is an explanation essay I arranged for you, which is for reference only and I hope it will help you.

Description 1 School meals are also worrying.

Once, eating was walking; Later, eating is running; Now, eating is in a hurry.

No, just after school, the "dust" on the playground is rolling towards the school cafeteria. The "hungry wolves" rushed at this "rich" food, and the scene was spectacular. After a while, a "long queue" appeared.

Alas, my friends and I decided to eat when there were few people waiting, but after waiting for more than half an hour, the "long queue" was shortened. There is no other way but to wait. I finally got my meal, but before I ate it, an annoying voice came from the radio: "Please return to the classroom for lunch break immediately." Listening to this speechless voice, we can't wait to beat him up now. The urgent task is how to solve the rice in our hands. After a heated discussion, we unified the front-take it back to the classroom to eat. I was ruthlessly treated as a "cannon"

Gray "-exploring the road, I looked around and found that there was no" enemy ". As a result, our party rushed back to our "base"-classroom with "trophies" in lightning speed. After a thrilling process, I finally ate the long-awaited hard-won white rice!

Alas, it's not easy to make a living in this world!

People say, "Guilin's scenery is the best in the world", but I think the scenery of the Yangtze River is also good. My family lives near the Yangtze River. I grew up drinking the Yangtze River water, so I know the Yangtze River very well.

The Yangtze River can be long, with no head in the east and no tail in the west, like a long dragon crawling on the land of the motherland. The scenery of the Yangtze River is very beautiful. The turbulent river flows from west to east day and night. Ships, large and small, only whistle on the river. The green trees and red flowers on both sides of the strait, or the green hills and white clouds, really make people feel beautiful. If it's in Jiangyin section of the Yangtze River in my hometown, you'll see high-rise buildings rising from the ground, factories dotted with high-grade highways criss-crossing, and a scene of prosperity.

The Yangtze River is rich in products. There is also the most famous Three Seasons of the Yangtze River. They are saury, shad and puffer fish. "Sanxian" is fresh and delicious, and everyone loves it. There are many fish and shrimp in the Yangtze River, and it is said that there are millions of species of light. Early in the morning, as soon as the sun rose from the horizon, the fishermen set sail in their fishing boats. In the evening, the setting sun shines on the river, "half the river is rustling and half the river is red." Everything is so beautiful. The fishermen came back whistling, and it was obvious that they were full of food. You see, baskets of fresh fish were carried to the dock and soon became a "fish mountain".

With the deepening of reform and opening up, there are more and more factories on both sides of the Yangtze River, because there are abundant water resources here, which are really inexhaustible. And backed by the Yangtze River, the transportation is convenient. The Yangtze River has also contributed a lot to the economic development of my hometown.

The Yangtze River sometimes loses its temper. It has a bad temper, it will burst its banks, flood farmland and wash down houses, but this is its punishment for human beings to destroy nature at will.

Yangtze River You are our mother river, I love you!

I have usually seen many flowers, but I like daffodils best. Noble and elegant, pleasing to the eye.

I believe everyone knows that there will be many daffodils on the market during the Chinese New Year, and then the family will definitely buy daffodils. But have you observed it carefully? Narcissus is very strange, with long green leaves, about 25 cm. After a while, daffodils grow some stems and some stamens. As soon as the breeze blows, the fragrance comes to my face and penetrates into people's nostrils, which makes people intoxicated. Drilling into the nostrils, I can't help but exclaim, "It smells good!"

Narcissus has a characteristic that it can survive without soil and water. I asked dad, and dad said daffodils can grow in soil, but they grow slower than in water. Oh, I see. The name daffodil comes from its rapid growth in water.

Dad said daffodils can bear fruit, but it's hard to see. I don't believe it, I can't even see a fruit! But when bees finish collecting honey in daffodils, the flowers will wither and naturally disappear. How I want to see daffodils!

Narcissus is introduced into people's nostrils with fragrance, which is amazing. But daffodils are still proud and continue to exude fragrance. I really like daffodils!

Composition 4 is the most common thing in the north. Walking in the street, you can see the flower wall composed of Chinese roses. In the greening of the community, among the flowers in the park and in the flowerpots on the balcony, there are Chinese roses. Every moment is dotted with people's lives.

The flowering period of Chinese rose is very long. It blooms every month except in cold winter, so it is called Chinese rose. Spring blooms early, autumn flowers wither, and Chinese rose flowers are still bright and charming. Chinese rose flowers are the most prosperous in April and May, with seven or eight flowers crowded on a cluster of cotyledons, and the flowers are competing to open and compete for beauty. Blooming flowers cling to each other and tightly wrap the stamens, as if afraid that the delicate stamens will be blown away by the wind. Buds in bud are swaying in the breeze, as if cheering each other up.

The vitality of Chinese rose is extremely tenacious. As long as the broken branches of Chinese rose are inserted into the soil, it will grow roots again, sprout, and then bloom bright and dazzling flowers. Su Dongpo, a great poet in the Song Dynasty, praised the Chinese rose in this way. "Flowers bloom and fall without interruption, and spring goes to spring and comes to nothing. Peony is the most expensive in the Spring Festival Evening, but it is only popular in early summer. It's just that this flower is inexhaustible, accounting for four seasons a year. " Although the Chinese rose is not as expensive and warm as the peony, it has the tenacity of always opening.

Although the Chinese rose is not expensive, it is dotted with every corner of our lives, and it has tenacious vitality. It is not feminine or artificial, and it is silently dedicated to this one that belongs to itself. There are also many people like Chinese rose in life, who work silently and selflessly in their posts. The sanitation workers on the street, the traffic police at the crossroads and the tireless teachers on the platform are all very inconspicuous, but they are very important parts. They can always bloom the most charming flowers inadvertently. Although ordinary, they are enough to make every passer-by feel subtle beauty and fragrance!

Since I entered school, I have a teacher, my good friend and dictionary teacher besides Mr. Ding. Teacher Ding taught me to use a dictionary. It turns out that dictionaries are very useful! It can help me understand the meaning of words, accumulate vocabulary and enrich my knowledge. I made friends with the dictionary!

The first dictionary I came into contact with was Xinhua Dictionary. When I first opened it, I was completely attracted by many words, sounds and meanings. Since then, I have developed a strong interest in dictionaries and can't put it down.

Whenever I read extracurricular books or magazines and come across words or polyphones I don't understand, I will look them up in the dictionary immediately. Sometimes my grandfather and I will argue about a word or its meaning. I'll look it up in the dictionary at once to settle the dispute between our grandfather and grandson. How interesting!

I also have an idiom dictionary, an English dictionary, a two-part allegorical saying dictionary and so on. With the growth of knowledge, Xinhua Dictionary can no longer meet my needs, so I made friends with Modern Chinese Dictionary with more words and rich contents. With it, I understand the meaning of some words and apply them to the article, which improves my writing level.

Dictionaries not only help me understand the meaning of words, but also help me acquire all kinds of knowledge, such as astronomy, geography, history, calendar, agriculture and so on. I know from the dictionary that Qin Shihuang was the first emperor in the history of our country, the distance between the earth and the moon was 384,000 kilometers, Zhang Heng invented the armillary sphere, Li Bing built Dujiangyan and so on. And I have a lot of common sense.

I feel that my good friend's dictionary is really profound. It can help me solve many problems and tell me a lot of knowledge. I respect and admire my friend's dictionary.

I have seen many TV advertisements, and my favorite is the public service advertisement of "protecting birds" inserted in CCTV's "Big Windmill" column.

In a big forest with birds and flowers, there is an old tree, and there is a beautiful nest on the high branch, where four little orioles live. Under the careful feeding of the little oriole mother, the little oriole has grown up, it's time to fly, and the chicks are playing happily. Suddenly, a black gun stretched out from a piece of green grass and aimed at a small oriole. Only one shot was heard. When the little oriole reacted and tried to fly away from the branch, it was too late. Its beautiful feathers were interrupted by bullets, so it couldn't fly high. It fell to the ground and the little oriole blinked.

This advertisement deeply shocked me. Birds and other animals living on the earth are friends of human beings. Why can't we live in peace with them? If we catch and kill indiscriminately for a long time, we will lose the best forest doctor and lead to the spread of pests. The earth where human beings live will definitely lose a lot of green. If we don't protect birds, I'm afraid we'll never see the picture of innocent girls in the park again. There are "flowers" but no "birds". The park naturally lost its original wildness and vitality.

I sincerely hope that all students will look at this public service advertisement, publicize the importance of protecting birds, and turn slogans into actions. I believe that with the joint efforts of the whole society, we will be able to "have birds singing everywhere around me" in the future.

I have a rectangular tin plastic-sprayed pencil case, which is 20cm long, 5cm wide and 2cm high. Except for patterns, Chinese characters and English, the rest are light blue, which is beautiful and generous. The exquisite design on the box surface is even more eye-catching: the lively little red rabbit is "smiling slightly" at me. And some naughty little oranges. They have different expressions: some are laughing, some are dumbfounded, some are sad and interesting.

The pencil case is not only vivid and beautiful in design, but also novel in style and convenient to use. Gently open the "gate" of "Stationery Castle", and you will find that there are quite a few stationery including "residence". The box is divided into two floors. There are pens and some ordinary pencils upstairs, all of which are cut and put there quietly, as if sleeping. There is also a black triangular fountain pen. Because the words written with a pen can't be erased with an ordinary eraser, correction paper has also joined the ranks of the "stationery team". Because this pencil box is not very big, I'm going to "embed" the correction paper on the lid. Open the upper floor, and the lower floor is divided into several compartments: slender compartments, which respectively "live" mechanical pencil and lead cores; Next to mechanical pencil, there are two "houses" of similar size. "Master" is a pencil sharpener and an eraser. They all lie on the ruler in obscurity, motionless and silent, and "sleep sweetly" on the ruler. In the west of their home, there is also a compartment, which is my folder, specially used to put notices, "small information" and other items.

Ah! Pencil box, you keep my school supplies and serve me day after day, year after year. Thank you. I hope you can spend a wonderful primary school time with me. You will always be my good friend.

My family has a pot of chlorophytum, which my mother bought the year before last and put on the table on the balcony.

The leaves of Dictyophora are light green, thin and short. A few weeks later, the wild leaves grew up and turned dark green, but it was very thin and long, with two white veins on the leaves. If it continues to grow, a small stem will grow from its root, and leaves will grow on the small stem. Small stems and leaves can be cut off and transplanted to other places, and new chlorophytum can grow. When the wind blows in from the window, the leaves dance and look beautiful.

It used to be thought that chlorophytum would only grow leaves, but now it is found that chlorophytum will also bloom. It was in late spring and early summer. I went to the balcony to bask in the sun and looked at the chlorophytum by the way. Just as I was leaving, I saw some white flowers the size of nails on the small stem. I was very surprised, so I observed these flowers. These flowers are about one square centimeter in area and have five petals. The stamen in the middle is golden, and I can smell the faint fragrance when a gust of wind blows. Some of these flowers have beautiful smiling faces and are graceful in flowerpots, like a proud peacock; Some put the petals together tightly, like a shy girl; Others are like a full stomach, which is about to burst.

My chlorophytum is really beautiful. I like it very much and often water and fertilize it. Under my careful care, chlorophytum grows sturdily!

In today's society, parents regard their only child as the apple of their eye and spoil them. Don't want them to get hurt. It can be said that "I'm afraid to put it in my mouth, and I'm afraid to drop it in my hand!" " A cartoon in a Chinese book today aroused my deep thought.

When eating, Xiao Ming didn't want to eat, so he put his feet on the table and made a mess. So, his mother sat beside him, coaxing him and feeding him. Dad stood in the chair opposite him, making all kinds of funny expressions and interesting actions, imitating the sounds of animals! Father twisted his ass from time to time and screamed, "Little Swallow, put on colorful clothes and come here every spring!" " "Mom opened her mouth as if to say," Honey, honey, eat quickly. Enjoy it! ""Xiao Ming can only eat some delicious food when he is laughing. At other times, he only cares about the toys in his hand.

After laughing, I thought, "What a doting child! Hey! Spoiling a child will hurt him!

At this rate, how can he become a person who contributes to society? How did he enter the society? In society, who will love him as much as his parents? Who will feed him bite by bite? In that case, who will build the future of our motherland? Who will make our motherland prosperous?

Parents, please stop doting on your children! Don't give them dependence, let them be independent once! If this goes on, they will become disabled people who are excluded from society!

Students, such love is unacceptable to us!

Many great discoveries and inventions are inseparable from careful observation. Lu Ban observed the sawtooth of grass and invented the saw. Newton observed the apple falling to the ground and found the earth attractive; Watt observed the lid of the kettle after the water boiled and invented the steam engine ... I also made many discoveries.

For example, one winter, I just woke up and opened the curtains to see what it was like outside after a heavy snow last night. I was shocked! There are several patterns on the glass of my window, some like maple leaves, some like birds, and some like flowers. They are all kinds of beautiful, just like window grilles. They are very beautiful. I really want to know how these beautiful window grilles are formed, but I can't understand this truth. I had to ask my sleeping father, and I tried to wake him up. "What?" Dad said in a daze, and I asked curiously, "Dad, how are these beautiful window grilles formed?" Dad took a long time to react and said slowly, "In winter, the water vapor in the indoor air will condense into' window flowers' when it meets very cold glass!"

After listening to my father's words, I cried happily: "I learned another little knowledge today!" " Today, I know what "window grilles" are. It depends on one thing, that is, careful observation. Many celebrities have discovered all kinds of wonderful things through careful observation. Children, have you observed them? What was observed?

On our balcony, there is a pot of thorn plum, which our family likes very much.

There are seven or eight branches of Rosa roxburghii, which are covered with thorns. From a distance, they are like long caterpillars struggling to climb up, as if there is something delicious waiting for them. His leaves are small oval, stretching during the day, round and green, just like pieces of jade; How long these leaves grow on the branches, forming clusters, very beautiful, like sharing the sunshine together; At night, its leaves will roll up and seem to be asleep.

Prunus spinosa is a very easy flower to grow because it is very tenacious. Whether it is cold or hot, or it is stormy, it always stands strong. Even if I forgot to water it for two months, it can still grow new leaves, as if to tell me, "nothing can stop my growth!" " .

Prunus spinosa is also a kind of flower. Every time my father waters it, it shakes its head and looks very comfortable. The next day, it will bloom red flowers to thank its owner for his care, so my father and I especially like it.

The thorn plum not only brought me a lot of happiness, but also made me understand some truth. Men should be as strong as thorns, grow and blossom.

The thorn plum is very beautiful. I love the thorn plum!

Hello, everyone, I am a huge whale. The biggest animal in the world is our whale. In our family, the largest whale is160,000 kg, and the smallest whale is more than 2,000 kg!

We live in the ocean, and many people call us whales because we look like fish. In fact, we are not fish, but mammals.

We have many kinds, such as blue whales, white whales, killer whales and so on. But in general, it can be divided into two categories: one is baleen whales, which have no teeth; One is the toothed whale, which has sharp teeth.

I forgot to tell you, I'm a blue whale. My name is Doudou. My figure is about 30 meters and my weight is about 70 tons. If I open my mouth, I can open it wide enough for ten adults to come in and out freely. Because we stay in the water for a long time, every time we go out for air, our nostrils will spray a water column as high as 15 meters, which is equivalent to the height of your five floors. Seen from a distance, it looks like a fountain. I have great strength, which is roughly equivalent to the pulling force of a medium-sized locomotive. How's it going? Awesome!

We whales are all treasures, my fat can be used to make soap, whale meat is nutritious, whale bones can be used to extract glue, whale liver contains a lot of vitamins, and blood and internal organs are high-quality fertilizers. So, we are hunted by human beings, alas! It makes us uneasy. 1 For this reason, we protested many times, but you humans always ignored it, and we lost many relatives. Why? Why? Can't you have a kind heart like Guanyin?

Now, our number has fallen sharply and is almost extinct. Humans! Please don't kill us again.

There is an ancient saying: Exercise your muscles and bones outside and your spirit inside, so martial arts is to keep fit and recuperate.

Wushu is a tactic of melee, which is completely different from foreign fighting. There are no rules in foreign fighting, only to knock down the opponent. China Wushu pays attention to dexterity and strength, and requires agility and quickness. Boxers are more adaptable and can create fists that can defeat the enemy and make things out of nothing. Inch strength is stronger, and he can break a board five centimeters thick between inch and palm.

I only know a little about boxing. Changquan and Shaolin Wushu are the most common boxing methods. Changquan routine can be described as the trend of the Yellow River. After a punch, the fist follows like the mighty Yellow River, and the fist is as powerful as the rushing Yellow River.

Vitality is the three elements of conditioning, and essence is yang essence. Abdominal qi. God refers to spirit and charm.

My wife is very particular about gas. With a certain degree of luck, she can hit all parts of her body with bricks without any damage. Of course, anger is hard to adjust. First of all, luck should hold her breath, and use internal strength to push her air pressure to all parts of the abdomen and Tian Tian's body, so as to make the body hard. Breathing and exhaling is a method of practicing Qi.

Most martial arts are unarmed, and of course there are swordsmanship, cudgel and internal skills. I won't list them one by one. I can romance all kinds of changes with my fists and fists, but in fact I am the first wisdom in China.

My family lives in Laoshan Mountain. We have many specialties here, such as apricots, cherries and tea ... The most famous one in Laoshan is tea. Laoshan tea has a lasting rhyme, and its tea fragrance is in Wan Li.

Its appearance is very good: Laoshan tea belongs to the category of green tea, and Laoshan tea tree is an evergreen shrub. The leaves are ovate, 3- 10 cm long and 2-4 cm wide, with short teeth on the edge. The flowers are white, and the flowering period is August-10. Tea tree is acid-resistant, alkali-resistant, wet and waterlogged-resistant, warm and cold-resistant. The climate in Laoshan area is warm and humid, with strong sunshine, and the frost period is longer than that in the south. Coupled with the large temperature difference between day and night, tea trees grow slowly and have enough time to accumulate nutrients.

Laoshan tea is more nutritious and tastes great! Laoshan tea is rich in nutrients, including polyphenols, caffeine, aromatic substances, protein, amino acids, vitamins and other ingredients beneficial to human health. Drinking Laoshan tea has the effects of exciting, relieving fatigue, quenching thirst and detoxicating, promoting blood circulation, softening blood vessels, clearing heart fire and improving eyesight. Especially in tea, the content of amino acids and caffeine is high, the leaves are thick, the tea soup is mellow and fresh, the color is green and moist, the aroma is elegant, it is resistant to brewing, the soup is light green and bright, the color, fragrance, taste and shape are good, and the lingering fragrance after drinking leaves the cheeks, which makes good tea lovers full of praise, enjoying the world and winning the crown in the East. The real taste of Laoshan tea comes from "five grades": tender tea buds+sweet spring water+a good tea set+a quiet environment+a calm mind.

Such Laoshan tea is fragrant and delicious, which makes people extraordinary and calm as water, makes people feel far away from the noisy and restless social life, and makes it easier for people to understand some valuable life truths. It can be described as quiet and far-reaching and memorable. What are you waiting for after reading these? Come and have a taste!

Things show that the composition 15 this year is really not a calm year, and the voice is high! Commodity prices, real estate prices, energy prices, and even instant noodles can't stand loneliness and start to increase prices. Banks can also tell people who have already bought a house that this is also a "price increase"! It's really vigorous, and the price increase continues. In June, the National Bureau of Statistics 1 1 announced the consumer price index of China in June 1 1 reached 6. 9%, not only the biggest increase since this year, but also the highest point since 1997. Judging from the published situation, the biggest increase is still the food price, which is 18 higher than before. 2%, in the food category, the price of pork rose rapidly, reaching 56. 0% (a horrible figure), followed by meat and poultry and their products, with an increase of 38. 8%。 According to the data from the Price Monitoring Center of the National Development and Reform Commission, the average retail price of pork per 500g in 36 large and medium-sized cities nationwide was 13 from February 3 to 7. 39 yuan. This is the ninth consecutive week of increase after the "Eleventh" pork price.

In the Year of the Golden Pig, pigs really let us see the nature of "cattle". It is no exaggeration to use "skyrocketing" to raise pork prices. In this uproar, ordinary people are afraid to eat pork, and the government will use the reserve meat, which will lead to frequent policies in various places. Even the canteen shouted "the price of meat has gone up recently, and the price of food in the canteen has been adjusted ..."!

We ordinary people have three fears: first, we are afraid of unemployment; The second is fear of getting sick; Third, I am afraid of price increases. The price increase involves the widest range and is also the most hated by our people. Since last year, domestic prices have been rising day by day, and the temperature in summer is getting higher day by day, which has caught us off guard.
