How to carve daffodils

Legend has it that narcissus is the embodiment of Ling Boxian. Actually, it is a perennial herb, belonging to Amaryllidaceae, which is abundant in Zhangzhou, Fujian, China. It has a history of more than 500 years and is one of the top ten traditional famous flowers in China. Hydrated flowers like to live in wet places and how long they live in water. If the temperature where it lives is high, it will absorb a lot of nutrients and grow a lot of leaves, but it will bloom less. People want daffodils to bloom more, have fewer leaves and have a long flowering period. What should we do?

The carved narcissus head should be soaked in water for about a day. After soaking the mucus in the rhizome, rinse it with clear water, and then gently wrap the cut wound with clean white paper (easy to remove later) to absorb water and promote root growth. The washed and wrapped narcissus heads are usually placed in purple sand narcissus pots. Spread clean and beautiful pebbles on the bottom of the basin, stabilize the narcissus head, and then inject clean water, and our work is basically completed.

The best way is to carve daffodils.

After getting the narcissus head for 3 years, we must first judge the pros and cons. The curved side of the bud exposed from the narcissus head is the front. The carving method of the front of the daffodil head is: first, cut off the scales and dry roots outside the daffodil head; Secondly, leave 1/3 of daffodil head near the root; Cut off the scales of the upper 2/3 parts layer by layer until the flower buds are exposed; Then cut off the edge of each blade tip, so that the bud will bend and grow to form a beautiful shape. Please be careful not to cut the bud when carving, so as not to affect the growth of the bud.

The daffodil basin should be placed indoors with less sunshine, the room temperature should be controlled at about 8- 10C, and the water should be changed every day. After 5-6 days, the buds of daffodils will grow out one by one, and the leaves will be curved. At this time, it grows rapidly, so the temperature should be adjusted in time to make it bloom near the Spring Festival. If the temperature and humidity are well controlled, the flowering period is generally about half a month. If the carving skills are exquisite, we will create pots of lifelike bonsai, such as "Goddess Scattering Flowers", "Flower Basket Welcoming", "Proud as a Peacock" and "Swan Spreading its Wings", which will make the fragrant and elegant daffodils more colorful and make people enjoy an art.

With the coming of the Spring Festival, the elegant daffodils stand on a clear water, slim and graceful, competing to open, emitting a faint fragrance, which will definitely add infinite interest to your Spring Festival and bring spring breath to your room.

Fiona Fang's theory.

I once read such a sentence: "Fiona Fang's world, Fiona Fang's people." I didn't understand it at that time, but when I think about it, the truth can benefit people for life.

The world is square and round, for example, the table is square and the ball is round. Everything is decided by the creator, and there is nothing to say. But since ancient times, people have been talking about Fiona Fang.

As the saying goes, "Fiona Fang lives on earth", you may think, Fiona Fang is just a geometric line, how can it become a way of life? In fact, this is the personification of Fiona Fang. There are only three ways to behave, square, round, or both. Fang Zhe, such as the famous Wei Zhi of that generation; Round, how to flow like Kun. Due to historical reasons, the square in people's minds is good, and the circle is naturally evil. However, in modern society full of contradictions, extreme Fang Zhengzhi people are often hit hard in society and don't know what they have done wrong; Those who are as smooth as lubricants please the powerful and gloat when they see the unlucky, but they don't know that something unexpected will happen. One day, the unlucky man will climb to the top of the mountain again, but he will lift a rock and drop it on his own feet.

It can be seen that square or circle is only a person's personality characteristics, and it is by no means a good way of behavior. A square is just sharp, which is easy to hurt others and yourself, while a circle is soft and tough, which cannot be completely denied.

Therefore, in today's complex society, Fiona Fang's combination of rigidity and softness is the best way to survive. Isn't Premier Zhou a man who combines hardness with softness? In this way, he cultivated his self-cultivation, ruled the country and leveled the world, and won the sincere admiration of the world. His diplomatic level surprised all countries in the world.

Therefore, Fang Zhengzhi people should learn to look at the world calmly and get along with others gently, because everything is the opposite, and Fang Zhengzhi people's impulsiveness, arrogance and helplessness may not be accepted by others and it is difficult to integrate into this society; Round people should learn to look at the world sincerely and get along with others honestly, otherwise others will be suspicious everywhere and guard against it everywhere, and it is difficult to talk to people and blend in with fish and water. Only the perfect combination of square and circle and the flexible use of both rigidity and softness can do things with half the effort.

The old saying goes, "The world, the world of Fiona Fang; People, people in Fiona Fang. " As a cross-century generation, we can't be square, let alone round. We just want to be Fiona Fang people.

How to write a picture composition

Watching (moonlit night) belongs to "composition with pictures". I wrote it after learning Zhu Ziqing's A Little Flag. Now, combined with this composition, let me talk about how to write a composition with pictures.

Secondly, we should use accurate, vivid and vivid language to describe the picture realistically, giving people the feeling of being there. When describing, you can use metaphors, personification and other techniques appropriately. For example, when describing several nearby mountains, I use the metaphor of "like a ribbon tied around my waist" to describe its foggy characteristics; When describing the river, the anthropomorphic sentence "The mountain reflects Shui Ying" is used to highlight the distinctive features of the river.

First of all, when introducing pictures, we should arrange the order reasonably so that readers can see the layout of the pictures at a glance. If I write this article, I will write the moon directly above the picture, then the peaks on both sides, and finally the Lijiang River in two rows of mountains. So that the article won't look messy.

Third, the article should write about the feeling of watching. After reading this painting, my outstanding feelings are "quietness" and "beauty". So when describing, it is written around "quietness" and "beauty". For example, "the ship seems to be moving silently and slowly." "The river is silvery white and connected with the night sky in the distance. It is a vast scene." These descriptions highlight the beautiful and quiet features of the picture, revealing love between the lines.

While writing your own feelings, you can also expand some associations appropriately to highlight the artistic appeal of the painting. After reading this format, I think of my childhood life and the scenery in the suburbs of the city.

To sum up, writing pictures should be organized, vivid, associative and affectionate.

The secret of snails

On Sunday afternoon, it was very sultry. I walked into the yard and fiddled with my father's "baby flowers and plants". Suddenly, I saw a snail slowly climb up the leaf. "Snails are pests or beneficial insects? Why does it always leave a long line where it passes? Where are its nose and eyes? " A series of question marks came to mind.

I ran into the room and asked my father who was reading the newspaper. Father smiled and said, "since you want to know the secret of snails, why don't you experiment yourself?" Yes! Why didn't I think of that! So I decided to try it myself.

"Are snails pests or beneficial insects?" First of all, I tried to test turtles and snails with various foods. I first picked up cabbage leaves, steamed bread, small mosquitoes, and then caught several snails, numbered them separately and put them in front of these foods. Probably they were so hungry that they crawled to their favorite food, but each snail chose cabbage leaves and chewed them, but they couldn't smell other foods. Soon, the leaves of cabbage were eaten up. Now, I have come to a preliminary conclusion that snails are pests.

Then I conducted a second experiment to analyze why snails leave a long line when they crawl. I grabbed the snail high. When its head stuck out of its shell, I tried to grab its body, but before my hand touched the snail, its head retracted again. I think this snail is really a "coward"! I tried several times in a row, but I didn't succeed. I am really depressed. At this time, my father came over and said, "I was discouraged at the beginning and wanted to be a scientist when I grew up!" " "I was so' excited' by my father and excited again. Suddenly, an idea crossed my mind, "Yes, yes!" "I am dancing with joy. I carefully cracked the snail's shell with a sharp stone, pulled out the snail's body and touched its bottom with my hand. I only feel some sticky, faint little things. What is this? I found the answer after consulting books. It turns out that the little thing is its feet, and the sticky thing is snail excrement, which helps snails crawl.

Finally, I want to see where the eyes and nose of the snail are. I put a cabbage leaf in front of a snail, only to see that the snail touched it with a pair of longer tentacles, then touched it with another pair of shorter tentacles below, and then gulped it down. I think: probably one pair is eyes and the other is nose. But which pair are eyes and which pair are noses? I took another leaf and another cabbage leaf of the same size and put it in front of another snail. Because the difference is not very big, the snail's eyes are useless: I can tell which one is a cabbage leaf and which one is a leaf just by touching it with my small antenna. Now, I have discovered another secret: the big tentacle has the function of eyes, and the small tentacle has the function of nose.

Through this series of experiments, I really gained a lot: I not only discovered the secret of snails, but also understood a truth: if I want to make inventions when I grow up, I must cultivate the ability to find problems and learn to solve them from an early age.

sunflower

When I was playing in the street as a child, I often sang such a song: "What bird loves to run? What bird loves to sing? What flowers bloom in the water? What flowers look at the sun ... "Among them, the flowers looking at the sun are sunflowers.

Sunflower, also known as sunflower. Why is it called sunflower? Just because the sunflower's disk will turn. Every morning, as soon as the sun comes out, the disc faces the sun. Sunflowers always face the sun from morning till night, no matter where the sun is. This is probably the origin of its name.

So, why is the sunflower tray always facing the sun? I remember when I was a child, I heard a legend that several sons of the sun god took turns to be on duty in the sky. One of the sons, feeling bored in the sky all the time, sneaked to the ground to play. But once he came down from the sky, he couldn't shine. He involuntarily fell to the top of a small tree. Over time, he grew up with the tree and gradually became a sunflower. At this point, he felt that the pie in the sky was still fun and regretted it. I want to go back to the sky, but it is impossible. From then on, he had to look at the Sun brothers who were on duty in turn in the sky.

Every day from morning till night, day after day, my eyes never leave the sun. When I went to middle school and studied botany, I had a scientific understanding of why sunflowers always face the sun. Botanists have found that behind the sunflower disk, there is a substance that has a particularly strong ability to distinguish light. This substance prefers yin to yang. In order to avoid light, the front of the panel constantly changes direction and always follows the sun. From this point of view, sunflower to the sun is not an act of god, but an instinct of life.

Sunflower is panicum miliaceum. In the mature season, he is seven or eight feet tall, eight or nine feet tall, or even more than a foot tall. There is a heavy golden flowerpot with the thickness of a cup on the stem. Against the fat sunflower leaves, it is really fascinating!

Sunflowers, like most plants, are planted in spring and harvested in autumn. Generally, the seeds are sown before and after the awn seeds, and the buds will break out in a few days. At first, the bud only grew two pods, both of which were dark green. The pod is thick, slightly oval, without any edges and corners, and the stem is smooth. When it grew to more than a foot high, its appearance and color changed completely. The previous dark green gradually faded. Each new leaf has a tip, and the whole leaf is peach-shaped. The stems are thick and short hairs grow at the same time. At the top, there is a small bud. At this time, as long as the water and fertilizer are suitable, it will grow up quickly. In June and July, when a person grows to a height, it generally does not grow to a very high place. Leaves as big as a banana fan gradually turn yellow from bottom to top, but only the buds at the top grow up quickly, like a big disk.

The petals around the disk are golden yellow and full of energy, as if guarding the earth. There are countless small yellow flowers in the flower tray, crowded together, but arranged neatly. When the sunflower matures, the big petals and small yellow flowers gradually fall off. Black sunflower seeds are exposed under small yellow flowers.

Sunflower can be enjoyed by people, but it is mainly a cash crop. Sunflower seeds can be eaten or pressed for oil; Sunflower stalks can be used as fences and fuel; Sunflower leaves can also be fertilized. ...

In early autumn, the sun shines on everything, and the sunflowers in the courtyard are facing the sun. Looking at this scene, I remembered myself and our party. ...

Oh, my friend.

Selected Reading of Composition (hereinafter referred to as Selected Reading) and I have been friends for 6 years. I kept every issue of Selected Readings for six years, and my first article was published thanks to her.

Her advantage lies in coming from and facing the majority of middle school students. Many of my classmates and I made friends with her because she was not so overbearing as XXX's guidance, nor so deceptive as XXX's writing collapse. She is just a "literary friend", which is commendable. Seeing her is like chatting with friends, from which you can gain something, which is of great benefit to thinking and writing. So she took root in the campus. This is the fundamental reason why she has become more and more prosperous in the past ten years!

My friend has "one advantage", "two advantages" and "three disadvantages" This is a comment I wrote to my friend.

My friend has two advantages: pleasing to the eye and helpful to writing. The articles she chose have a strong sense of the times and a strong campus atmosphere, recalling things around her and expressing the feelings of her peers; The majestic sunrise on Mount Tai, the interest in climbing Langya, the friendship of teachers ... these ordinary and unique feelings and scenes often make me excited and memorable. This is from the appreciation aspect; My friend gave me the greatest help, but I was still writing. Reading the articles in the book is the most important teacher who led me into the hall of Catch a Knife. The selected articles in each issue were read by the teacher in the composition class, and I went home to study by myself. My composition conception, language and sentence making are greatly influenced by her. I often open it when I write articles, and I draw lessons from the wonderful paragraphs marked with red pen when I was reading. I really like this friend!

However, my friend's shortcomings often make me shake my head. I have three ideas.

First, the evaluation of the selected articles is thin. It is of course important to guide everyone to improve their writing level and choose a good article as a model essay. What is more important is to evaluate the concept, structure and words of the model essay. Let an experienced teacher analyze it in detail, and its function is no less than listening to a text: at this point, can the method of "Bao Wen" commenting on students' compositions in brackets and then commenting in detail be referenced?

Second, there is little practice in the design of selected texts. Excellent exercises published in selected readings are always unique in some aspects. Let the author design some exercises by himself, which can communicate the understanding of the article between the author and the reader and improve the reading interest at the same time. At this point, the reading communication in the three northeastern provinces is very distinctive. Can you learn some classics?

Third, the manuscript is not wide enough. In the future, we should give middle school students in Nanjing a chance to shine in the selected reading! Although I am about to graduate from high school, I will always be my friend!

History of housing development

House is the place where human beings live, and it is a symbol of human conquest of nature and their own development.

It was not until Banpo clan period that human beings created their own houses entirely by their own labor-stone houses piled up with their hands. The roof of this stone house is covered with grass and has a conical shape. The house is irregular in shape, and half of it is below the ground. Together, several such houses became the village at that time.

Later, with the development of human culture and technology, people began to build houses according to pre-designed schemes. As a result, people carved and scientifically spliced wooden houses and stone houses, as well as various forms of wooden, stone and earth houses were built in large quantities, and even developed into large-scale palace buildings and temple buildings. Due to the differences in history, culture or customs, people of different nationalities have created different types of houses. The bamboo building of the Dai people in Yunnan has two floors, with people living on the upper floor and horses tied on the lower floor, which is convenient, safe, cool and hygienic. People on the loess high slope adjust measures to local conditions, dig holes to build houses and build rows of caves that are warm in winter and cool in summer; The Mongolian people on the grassland even created a movable house felt bag to shelter from the wind and snow and move at will. There are many kinds of houses, all of which show the hardships and greatness of human creation.

Great changes have taken place in the essence of modern housing. People no longer rely solely on natural materials, but use artificial materials such as reinforced concrete and pay more attention to the decoration inside and outside the house. For example, the walls are inlaid with tiles and even coated with gold powder, which makes the houses resplendent and dazzling. These buildings, both in structure and appearance, far exceed the ancient houses.

People are engaged in activities in different houses. It can be said that the house has become an indispensable part of human living environment.

As we all know, humans have been separated from animals since the day they learned to make tools. Since human beings can make and use tools, of course, while filling their stomachs, they also thought of creating a comfortable habitat for themselves.

Modern society has entered a period of rapid development of science and technology. There has been a new breakthrough in the performance and function of the house. For example, some houses can resist earthquakes. A fortress-like house in California experienced a 6.2-magnitude earthquake, but it was "unmoved"; Some houses can simulate the space environment outside the earth and become space stations on the earth.

Modern housing is no longer just a shelter for people, but provides laboratories and workshops for production, scientific research and all the development of modern civilization.

Due to the rapid increase of population and the huge demand for housing, people have to develop into the sky, so skyscrapers have sprung up. According to statistics, a 300-story skyscraper can accommodate the population of a medium-sized city.

The earliest houses should be pushed into caves covered with hay, where cave people lived. I'm afraid this kind of house is more a gift from nature than human labor.

With the development of science and technology and more and more human desires, in the future, human beings will not be satisfied with living only on the earth continent, and the appearance of "Dragon Palace under the Sea", "Planet Villa" and "Castle in the Air" is probably not far away. The pupil outdoes the master.

Hometown rice noodle

When you are a guest in my hometown, the hospitable host will always offer delicious fried Xinghua rice noodles for you to taste, especially for those who go to Taiwan Province, foreign Chinese and overseas Chinese, and the traditional hometown food-Xinghua rice noodles is indispensable at the banquet. At this time, the rice noodles in my hometown have become the treasures of Taiwan Province compatriots and overseas travelers. At this moment, they are always filled with emotion, even full of poetry. A Xinghua native who came back from the other side of the Taiwan Strait once ate rice noodles from his native land and sighed with passion: "The silver line broke, and the two sides of the Taiwan Strait were shocked by it. The descendants of Xinghua sang a song across the sea." Expressed the feelings of compatriots on both sides of the Taiwan Strait looking forward to the reunification of the motherland.

Why Xinghua rice noodles are charming? It turns out it has a long history. According to legend, during the Northern Song Dynasty (1064- 1068), the court appointed Bo Lifan, the leader of Xinghua Army. In Xinghua, water was smelted into a Mulan pond. Later, Qian Siniang, his right-hand man, died in Mulan River because of the failure of building a pond. Li Fan was fearless in the face of danger and bravely presided over the project himself. In order to reward migrant workers, Li Fan made public the processing technology of brown rice flour handed down by his ancestors, and also produced a large number of rice noodles. Not long after, Li Fan was also killed in the investigation of the construction site. People offered rice flour and rice wine to this river and built a "Li Fan Temple" for it, which will be remembered for generations to come. The rice flour industry initiated by Li has blossomed in the beautiful and rich Xinghua Plain. After several generations of continuous reform and innovation, rice flour with local characteristics in Xinghua has gradually formed.

When you eat delicious fried silver silk-Xinghua rice noodles, have you ever thought about the hardships of making Xinghua rice noodles in the old society? Indeed, in the old society, making rice noodles by hand was an extremely arduous and complicated heavy physical labor. Its production process is divided into more than ten processes, such as soaking rice, milling rice, drying, kneading noodles, steaming, rice arrangement, pulp removal, making handles, drying in the sun, waist binding and so on. Every process is soaked with the bitterness and sweat of rice farmers. It's really a rice noodle, a string of sweat, as evidenced by a poem: "After falling asleep in the middle of the night, my limbs are chapped and sweaty, leaving a meter of soup for enema."

Xinghua rice noodles are not only mellow and delicious, but also fragrant all over the world. Today, with the opening to the outside world and invigorating the domestic economy, Xinghua rice flour is a wonderful flower of township enterprises. Its products have entered the international market, selling well in Japan, Southeast Asia, Europe and America, earning foreign exchange for the country and contributing to the four modernizations. Powder farmers in Putian make mellow rice noodles for human beings and brew a sweet life for themselves. You see, the rows of red brick tile houses rising from the vast Mulan River are not the new homes of the flour farmers?

The riddle says "four corners, straw around the waist", and the answer is "Xinghua rice noodles". It turns out that Xinghua rice noodle is a square rice replica, tied with straw in the middle, glittering and translucent and white. Its white stripes are thin, elastic and tough, and it is convenient to cook and fry. Soup is salty and easy to dry. If it is served with fish, meat, eggs and vegetables, it really makes people salivate. No wonder Zhu, a famous scholar in the Song Dynasty, couldn't help clapping his hands and applauding when he tasted rice noodles while giving lectures in Xinghua: "It smells good." Now people pay more attention to the cooking methods of Xinghua rice noodles, and there are many ways to eat them. "Basu fried rice noodles" is one of them. The so-called eight elements are "mushrooms, lilies, fungus, laver, gluten, dried silk, bean curd skin, vegetables and colorful crispy peanuts, which are beige and tender, fragrant and delicious, and complete in shape. Anorexia patients and hard-working people will see their beauty. Xinghua rice flour is also a panacea for colds. As long as the ginger, onion and bean paste that have survived the oil are added to the rice noodles cooked in the soup, the patient will eat it while it is hot, and then wrap it in a quilt, sweating like a pig, and the high fever will be dispersed.

In the horn of the four modernizations, those heavy and backward manual operations were all replaced by machines, and the painful whines and groans in the old workshops were all replaced by the roar of motors and relaxed and happy pop songs. With the progress of science and technology, Xinghua rice noodles are also sprinting to new heights. At present, a kind of "fast food" rice flour is made by adding various nutrients and condiments according to a scientific formula. As long as the rice noodles are cooked, they are really delicious "fast food", which provides convenience for tourism and people's diet.

May Xinghua rice noodles, a traditional local product, radiate more brilliant light in the era of reform and opening up.
