Describe the suspension bridge and write a composition.

1. Composition about Lishi Suspension Bridge 500 words Students, you must cross the suspension bridge! No, on this cloudless day in Wan Li, my classmates and I will also reflect on this "masterpiece" of fear.

Come to the suspension bridge in Quanshan Park. I began to cross the suspension bridge, and curiosity drove me to summon up courage to move forward. Some students of suspension bridge are eager to try, while others are timid and shy away. I craned my neck and looked at it, and I couldn't help shivering. A dozen meters away from the river, there is a suspension bridge made of wood. The suspension bridge is less than half a meter wide, and there are no handrails and railings beside it. Under the rickety bridge hanging in mid-air is the rushing river, which makes people feel scared. I hesitate: go up or not? Looking back, the bridge was already crowded with classmates, and no way back was gone. I got up my courage and thought: what a rare experience it is to cross the suspension bridge, but isn't it a waste of time? In this way, I carefully walked onto the suspension bridge that I had been hanging around, with my hands stretched out horizontally and my feet stepped on some loose boards. I took the first step by shaking, and the suspension bridge creaked, but it seemed smoother than I expected. I quickly stepped up and came to the middle. Just when I was secretly happy, suddenly, I tripped and the suspension bridge shook violently. At this time, the students' encouragement came from my ears: "Xiaolan, don't look down, keep your head up and go forward, believe in yourself, and you will definitely pass!" " "My heart seemed to calm down at once, raised my head, straightened my chest, gained a foothold step by step, and made steady progress. Finally, I won and reached the other side.

Crossing the suspension bridge not only exercised my courage and improved my courage, but also made me understand a truth: to overcome difficulties, we must first overcome ourselves. Only by overcoming our inner fears can we overcome obstacles more confidently and succeed step by step!

In my eyes, just after the Spring Festival last year, my parents and I traveled to Jinfo Mountain. On the way, I crossed the suspension bridge for the first time by myself.

That afternoon, the weather was fine, and we went to Wolongtan, the first stop of Jinfo Mountain. Surrounded by mountains, shaded by trees, flowing water and beautiful scenery, it is really a famous scenic spot in China! Our group walked on the plank road in the scenic spot, intoxicated by this picturesque beauty. From time to time, there was a clear birdsong in the distance. In the middle of the river not far away, there are some monkeys playing. It's still daytime, isn't it?

Just then, we finished the plank road. Suddenly, I don't know who shouted, "Look, suspension bridge!" " "I looked up, and the road ahead is S-shaped. To cross the river, there is a suspension bridge made of wooden boards and iron cables more than ten meters high from the river! There are swift rivers and pebbles of different sizes under the bridge. Someone stepped onto the bridge and staggered, which made me jumpy and uneasy. I thought to myself, "should my father carry me across the bridge this time?" "I dare not go there myself." At this moment, mother said, "Son, you are going to cross the suspension bridge. Be careful."

"Bang", my heart is beating rapidly with my mother's voice. I chickened out and looked at my father timidly, hoping that my father could help me. Dad may have read my mind and squatted down and whispered to me, "son, you have grown up and are a little man." I believe you can do it. " So, mom is in front, you are in the middle, and dad is in the back, okay? "I nodded and decided to try it myself. Besides, there is a child younger than me in front who went by himself. How dare I let my father carry the past?

In this way, with the encouragement of my parents, I carefully walked onto the suspension bridge that had been shaking. I gripped the iron rope of the suspension bridge with both hands, stepped on some loose boards, and took the first step forward with trembling body. "Very well! Son, walk slowly and look forward! " Dad reminded me in the back. I saw my mother looking at me approvingly at the other end of the bridge and smiling at me. My heart suddenly calmed down a lot, and I quickened my pace. Just when I was secretly happy, suddenly, my foot was stirred by something, and my body stumbled forward involuntarily and almost fell. But at this moment, the suspension bridge shook violently and a board on the bridge almost fell off. I glanced at the river with my eyes and felt as if I was suspended in mid-air. In case I was shaken into the river, I closed my eyes and didn't dare to think any more. I can't help but panic, my legs are weak, and I am scared to tears. "Son, hold on, don't look down. You know, you're great. You will arrive soon. " Just when I was about to give up, my father cheered me up behind my back. Suddenly I thought of the TV series "Long March" I watched not long ago, and the scene of the Red Army crossing the Dadu River. There are no planks on the iron cable bridge, and the Dadu River under the bridge is more turbulent. However, the Red Army bravely crossed the river despite difficulties and dangers. Thinking of this, thinking of my father protecting me behind me, my heart calmed down again. I stood up straight, grabbed the iron rope, stepped on my heel step by step, and finally reached the other side. I breathed a sigh of relief, and my parents praised me for being brave. Next, I did the same thing and easily passed the suspension bridge behind me to Songziyan, the highest point of Wolong Lake.

I stood on Songziyan, overlooking the suspension bridge like a dragon at the foot of the mountain, and I was still worried. But when I saw the wonderful scenery on the top of the mountain and the afterglow of the sunset sprinkled on my face dripping with crystal sweat, I said excitedly in my heart, "I finally crossed the suspension bridge by myself, which is great!"

3. Composition of suspension bridge The suspension bridge consists of two pavilions, some wooden boards and chains, and the chains are wrapped with colorful lights, which are beautiful.

At night, the colored lights on the suspension bridge light up one after another, which looks like a paradise of stars from a distance. Whenever night falls, I will go to the suspension bridge to play.

After the first pavilion, I came to the beautiful suspension bridge, and walking on it was like getting drunk. Slowly I came to the second pavilion. The first pavilion and the second pavilion are similar in structure, just like twins.

The suspension bridge leads to an island. The scenery on the island is beautiful. There are trees and grass on it. I sat in the pavilion. The pavilion and chairs are all made of stone. It is cold and comfortable to sit on it.

I looked at my watch. It's getting late. I stood up and walked back. Walking on the suspension bridge is like swinging. I can't forget the fun it brought me.

I got off the suspension bridge, looked at the splendid suspension bridge and went home reluctantly.

4. Introduction to the use of suspension bridge A suspension bridge with more than 1,000 words refers to a bridge that suspends cables (or steel chains) and anchors them on both sides (or ends) of the bridge through cable towers as the main load-bearing components of the superstructure.

The geometric shape of cable is determined by the balance condition of force, which is generally close to parabola. Many suspenders are hung on the cable to hang the bridge deck. Stiffening beams are often installed between the bridge deck and the suspenders to form a combined system with cables to reduce the deflection and deformation caused by live load.

The history of suspension bridge is very old. Early tropical primitive people used rattan, bamboo and trunk as suspension bridges to cross streams in the forest. The cables used are vertical, cable-stayed or both.

The primitive rattan and bamboo bridges in Borneo, Laos and Java are the embryonic form of early suspension bridges. However, the earliest recorded prototype of suspension bridge belongs to China, which is still affecting the development of suspension bridge forms in the world.

As early as the 3rd century BC, a bamboo cable bridge was built in Sichuan, China. Qin took the West Shu, and Sichuan's "Yanyuan County Records" recorded: "In thirty years (285 BC), Qin set Shu as a garrison, but the book said that it was stable.

By the time Li Bing was Wei (256-25 BC1), seven bridges had been built. Among these seven bridges, there is a bamboo cable bridge. Visible, at least in the third century BC, China has a record of bamboo cable bridge.

As early as 50 BC (that is, the fourth year of Ganlu, Xuan Di, Emperor Gaozu), a 100-meter-long iron chain bridge was built in Sichuan. 1665, Xu Xiake wrote a travel note "Tie Suo Qiao Ji", which was translated to the west by missionary Ma Tianni. The book records in detail an iron cable bridge at 1629 in Guizhou, with a span of about 122 meters.

1667, after returning from China, French missionary kircher wrote The Miracle of China, which recorded the Tiesuo Bridge in Jin Lan, Yunnan in 65 AD. This book has been translated into many languages and reprinted many times.

According to the research of historians of science and technology, the cable bridge spread to the west only after the publication of the above books. It can be seen that the ancient suspension bridge in China is original and leading.

The famous Luding Bridge, consisting of nine chains on the Dadu River in Sichuan, was built in 1706. Suspension bridges appeared earlier in Yunnan. According to Xu Xiake's Travels and Yunnan Travel Diary, Tengqiao Cloud of Dongjiang River in Longchuan, Yunnan Province: "The source of Dongjiang River in Longchuan died in the south.

The development of suspension bridges in modern China began with 1938. A highway suspension bridge was built in Hunan, which can run 10 tons of cars, and then a number of highway suspension bridges were built. After the founding of New China, more than 70 such bridges have been built, but their development is seriously lagging behind because of their small span, narrow width and low load standard.

After 1990s, China Suspension Bridge opened a new historical chapter. Shantou Bay Bridge with a main span of 452m is known as the first long-span modern suspension bridge in China, and its main span ranks first among the prestressed concrete stiffening suspension bridges in the world. Xiling Yangtze River Bridge, with a main span of 900 meters, is the first all-welded steel box stiffening girder suspension bridge independently designed in China. Jiangyin Yangtze River Bridge in Jiangsu Province is a steel box stiffening suspension bridge with a main span of1385m, which is the fifth largest suspension bridge in the world. The south branch bridge of Jiangsu Runyang Yangtze River Highway Bridge, completed in 2005, has a main span of 1490m, which is the third largest suspension bridge in the world. The recently completed Xihoumen sea-crossing bridge in Zhoushan, with a main span of1.650m, ranks second in the world.

It can be seen that China has entered the advanced ranks in the world. Aizhai Extra Large Suspension Bridge is located in Aizhai Town, Xiangxi, Hunan Province.

Aizhai suspension bridge, about 20 kilometers away from Jishou city, passes through the valley near Aizhai town, and the Dehang River passes through the valley bottom. The design elevation of the bridge deck is about 330 meters from the ground. The bridge type scheme is a single-span suspension bridge with steel truss stiffening beam, with a total length of 1073.65m and a main span of1176 m.

The bridge spans the Aizhai Grand Canyon, ranking third in the world and first in Asia. The construction of modern suspension bridges in China began in the 1960s with 19, and some semi-stiffened single-chain and double-chain suspension bridges with spans less than 200m were built in the southwest mountainous areas, among which the famous one was Chongqing Chaoyang Bridge built with 1969. Tibet Dazi Bridge, 1984 completed, with a span of 500 meters.

The traffic construction in 1990s finally ushered in a new era of building modern long-span suspension bridges. Guangdong Shantou Bay Bridge with a span of 452 meters adopts concrete stiffening beams; Humen Bridge in Guangdong is a steel box girder suspension bridge with a span of 888 meters. The main span of Jiangyin Yangtze River Bridge1200m is under design.

The simultaneous construction of three suspension bridges will enable China's bridge science and technology to quickly catch up with the advanced world level.

5. I love the composition of Suoqiao in my hometown. My hometown is a beautiful town with mountains on one side and water on three sides.

A clear and winding river dotted the town and slowly flowed eastward. At the end of the south gate of the town, a cable bridge across the Xujiang River is like a rainbow lying on the waves, spanning the west bank of the Xujiang River.

Before entering the cable bridge, you can see the four characters "Xu Jiang Cable Bridge" shining in the bright sunshine. The whole bridge composed of steel bars and cement is firmly fixed by several thick and long steel cables.

It is more than 400 meters long and 1 1 meter wide. There are also wooden sidewalks on the left and right sides to reduce the weight of the bridge.

To get on the bridge, you have to get on a long ramp-like approach bridge from the right side of the main approach bridge. There stands a black stone tablet, which records the construction information of this bridge.

During the day, the bridge is full of traffic and people come and go. City people cross the bridge to the suburbs to relax and enjoy the scenery in the fields.

Farmers sell agricultural vegetables and fruits across the bridge. Everyone was beaming.

On summer nights, the bridge is breezy and the neon lights twinkle with the bright stars in the sky. Wonderful singing, cheerful laughter and the sound of running water together constitute a paradise on earth.

6. Composition of Mitan Yellow River Suspension Bridge At present, the composition of suspension bridges is mostly reinforced concrete, with strong modern craftsmanship and few wooden bridges. Occasionally, it's just for appreciation or something. However, there are still some suspension bridges in Guizhou villages in mountainous areas.

The suspension bridge in this mountainous area is not supported by steel cables like scenic spots, and its safety and artistry are very reliable. Most of these suspension bridges are about five to twenty meters, and they are usually placed at the waist of two mountains, which is the same height as the mountainside. Both ends of the hemp rope are tied to a stake. A suspension bridge usually has two to five hemp ropes, at least not less than two. Bridges are mostly paved with wooden boards, ranging from paving to half a meter interval, so the safety is not high. The suspension bridge with the largest plate spacing is nearly one meter. Children are forbidden to pass, even adults can't step on one foot. This is the most dangerous suspension bridge. In addition to the single-plank bridge, the hanging wooden bridge is the oldest bridge in the history of Chinese bridges, which can be seen from the simplicity of equipment and technology.

7. Write a composition about writing a bridge (eight articles). Is it okay to write about the bridge of friendship? The Bridge of Friendship Honesty is the foundation of being a man and the supreme virtue.

Only when human beings have integrity can they trust each other, communicate with each other and build a bridge of friendship. To be an honest person, we must first correctly understand what honesty is.

Honesty means honesty, trustworthiness and trustworthiness. No matter in life, study or future work, as long as there is a crowd, as long as it is in contact with people, we must adhere to this principle.

In this way, we can become a capitalized person, a trustworthy and reassuring person, and a noble person. In life, if you don't lie, tell the truth and do honest things, you must fulfill your promise to others, and you must try your best to do it well.

George Jr. is such a good example. One day, when his father was not at home, little George found a small axe at home, so he happily took it to his father's beloved small cherry forest. With a sharp axe, he curiously slipped on the trunk of the cherry tree and the cherry tree fell to the ground.

At dusk, my father came back and was surprised: "Who cut down my cherry tree?" Little George ran honestly: "Dad, I'm sorry, I cut down the cherry tree with a small axe!" " Dad smiled kindly and said, "Little George, your honesty is better than a thousand cherry trees." "In learning, either cheat teachers, students or themselves, cheat in exams or cheat, learn true knowledge, true knowledge, true grades and true scores.

In the future work, we should strive to complete the tasks assigned by the organization, not be lazy, stress credibility, not cheat, be loyal to our duties, work hard and be conscientious, just like Ren Changxia, a good guardian of the people. Starting from me, starting from now.

Let's all take active actions, be honest people and do honest things, so that the bright light of honesty guiding human progress will be brighter. If not, there is one in this article. When you face the cliffs, you are eager to cross the natural barrier with her, and when you face the rapids, you hope to reach the other shore smoothly with her. Some people say that when we lose our way and stop in the journey of life, we need her more, and we need her to see the spectacle of "another bright village" when we are "surrounded by mountains and rivers and there is no way to recover". It is an ordinary "bridge"! In my heart, there is a bridge that guides my life direction and accompanies me through every day.

Mother is the bridge, and mother is the bridge that leads us to life. From a special cell to a complete life.

Mother built a bridge of life for us with her body and nutrition. After crossing this bridge, we will move towards life and a completely repaid world.

Father is the bridge, and father is the bridge to cultivate our personality. From a crying baby lying in the cradle to a teenager with a unique personality, his father built a bridge of personality with his tolerant heart and concise and rigorous words.

Walking through it, I understood my father, and walking through it, I felt my father's tolerant heart; Through it, we will have the minimum personality as human beings. The teacher is the bridge, and the teacher is the bridge of dedication that guides us to get rid of ignorance.

From that extraordinary age-6 years old, under the guidance of our teacher, we rode our own route and braved the wind and waves in the ocean of knowledge! In the pursuit of wind and waves and competition with each other, we know "ourselves" and "ideals", what is the value of life and what is the true meaning of life. From the initial ignorance to becoming a thoughtful teenager and teacher, this most glorious bridge under the sun has been guiding us to the ideal glorious hall with life and youth, with no regrets.

Walking through this bridge of dedication built with sweat and painstaking efforts, we will understand what is called "teacher", what is called "selflessness" and what is called "dedication". A friend is a bridge, and a friend is a bridge of friendship built with the most precious feelings in the world.

When we face the challenges of life and are a little timid; When we were beaten black and blue by failure; When we were carried away by victory and lost our way; When we are almost desperate at the mercy of bad luck ... this bridge always reminds and helps us. Walking through this bridge of friendship built by sincere heart and mutual understanding, we understand the meaning of "communication"; Walking across this bridge, I just want to shout: "Long live friendship!" " People will encounter many "bridges" in their life, which help us cross the "natural barrier" and the "dangerous beach" of life; These "bridges" guide us in the dark and guide us in the right direction; These "bridges" help us get rid of cowardice and ignorance, strengthen our confidence, grasp our destiny, and help us know ourselves and grasp ourselves.

Bridge is a beautiful landscape in the journey of life; Bridge is a compass, which defines itself on the road of growth; The bridge belongs to you, me and him all his life, golden road! Or there is something in this article. When you are facing a cliff, you are eager to cross the natural barrier with her. When you are facing a rapids, you hope to reach the other shore smoothly with her. Some people say that when we lose our way and stop in the journey of life, we need her more, and we need her to see the wonders of "a bright future village" when we are "surrounded by mountains and rivers and there is no road to doubt". She! It is an ordinary "bridge"! In my heart, there is a bridge that guides my life direction and accompanies me through every day. Mother is the bridge, and mother is the bridge that leads us to life.

From a special cell to a complete life. Mother built a bridge of life for us with her body and nutrition.

After crossing this bridge, we will move towards life and a completely repaid world. Father is the bridge, and father is the bridge to cultivate our personality.

From a crying baby lying in the cradle to a teenager with a unique personality, his father built a bridge of personality with his tolerant heart and concise and rigorous words.
