1. Dear Mother River: Hello! I am a sixth-grade pupil and one of your children.

When I write to you excitedly, I can't help thinking of your generosity, your selflessness and your greatness. Mother River, you are so beautiful and young, and you have given us life, dignity and enthusiasm. You flow from the mountains to the sea to nourish the fertile fields; You flow through every child's heart, and you will be civilized forever; You are our mother, selfless dedication, raising millions of children, but now you have experienced vicissitudes.

I know, now, your beautiful and clear face has become dark, turbid and smelly. What's going on here? It turned out to be a "good thing" done by heartless people.

The paper-making, textile, chemical and other factories next to you discharge a lot of industrial wastewater to you; Livestock and poultry farming also discharges sewage into your body; There are many people living near you, and the domestic sewage and garbage are littered ... You seem to be crying silently, crying for the sewage in your heart and crying for the ingratitude of human beings ... In my dream, I saw that your face is no longer black, muddy and smelly ... Ah, you are the beautiful mother river in the past! When I cheered, the dream broke, and the beautiful mother river in the dream broke. I woke up ... human, why are you so cruel to your mother and me? The good news is that not everyone is so cruel to you. Now, the city * * * has mobilized many people to join the action of "protecting the mother river" through publicity, and spent hundreds of millions of yuan to punish you ... Have you seen it? I think you must be very happy ... Mother River, now your face is gradually becoming clear. I seem to see your long-lost smile, so sweet, so sweet ... Mother River, you must forgive our ignorant children. We were wrong. We will treat you well and protect you. We will prove it with practical actions.

Thank you for educating us with a broad mind: to protect the environment, only green mountains and green waters are our eternal wealth; We also remember your teaching: don't trade green mountains and green waters for Jinshan Yinshan, and we will always remember this teaching! This is a salute.

2. Please write a short essay about 100 words on the topic of Three Gorges of the Yangtze River for your reference, and revise it yourself. In the early morning, the transparent road water is glowing, and the downwind is a little cool, as if the orange pomelo trees all over the mountain have taken off a layer of frost, fresh and clear; The sun came out, the water on the road disappeared, the orange trees shone with this sunshine, and the green leaves of Jinshixia were bright and beautiful in autumn.

At noon, the peaks were covered with golden armor. In the afternoon, before sunset, a layer of blue fog got up early.

Since ancient times, people have admired the magical masterpiece of nature-the Three Gorges of the Yangtze River. Look at the magnificent Kuimen, the beautiful goddess peak, the beautiful Three Gorges ... the ancient factories are vividly in my mind.

Today, I finally have the honor to come here and find that seeing is believing. I have enjoyed the magnificent Yellow River and the crystal clear Lijiang River, but I have never seen such water as the Yangtze River.

The water in the Yangtze River is really long and winding for thousands of miles. The water in the Yangtze River is really deep and you can see it at a glance. When you drop a stone, you only hear a plop and the stone disappears. The water to the Yangtze River is really urgent, like an old woman going to the market, flowing anxiously and patiently. I've climbed the Red Leaves Xiangshan Mountain and swam to Wudang Mountain, a Taoist resort, but I've never seen the mountains here in the Three Gorges.

The mountains of the Three Gorges are really strange. They rise like goddesses and lions ... the mountains of the Three Gorges are magnificent and continuous. They are really green, deep, shallow, bright and dark ... The green hills of the Three Gorges are too wonderful to describe. "Guanyin sitting on the lotus platform" and "Jiulong protecting Ganoderma lucidum" ... each peak has its own characteristics and each peak is unique. This mountain is surrounded by this water, which nourishes this mountain. Coupled with the constant singing of apes on both sides of the strait, the trees in the gorge are strange and the ships on the river are speeding, which makes people seem to enter a continuous picture.

Hope to adopt, O(∩_∩)O Thank you.

3. The topic of the composition is "borrowing scenery to express emotion". One day in the summer vacation, my mother took me to play in the Yangtze River.

The next day, we came to the Yangtze River. I get up early.

In the morning, a mist rose on the river. After embroidering this mist, I saw the Yangtze River flowing slowly. At this time, the Yangtze River is still sleeping.

I breathe the morning air, which makes me refreshed. At noon, the sleeping Yangtze River woke up.

At this time, the Yangtze River began to get busy. The current is fast, just like a naughty boy rolling up a whirlpool.

The Yangtze River sometimes sings. Listen to the noise. This is a masterpiece of the Yangtze River. In the evening, the sun went down and the river was covered with a layer of golden yellow.

I was standing on the boat watching the beautiful evening when suddenly a little brother asked me, "Eldest brother, who paved the Yangtze River into golden yellow?" At this time, the busy Yangtze River seems to feel a little tired. The locals say that the scenery of the Yangtze River during the day is not as good as that at night.

As night falls, there is a bright full moon hanging in the dark sky, reflected in the Yangtze River, as round as a hundred, as if there is a full moon in the Yangtze River. It was beautiful late at night, and the Yangtze River, which had been running for a day, gradually calmed down.

It looks very quiet in the beautiful moonlight. Now I want to visit the beautiful Yangtze River.

Wuhan Yangtze River Bridge is located on the Yangtze River in the northwest of Nanjing, connecting the urban area and Pukou District. This is the first double-deck railway and highway bridge designed and built in China. The highway bridge on the upper floor is 4589 meters long, and the roadway width is 15 meters, which can accommodate four large cars at the same time, and the sidewalks on both sides are more than 2 meters wide. The lower railway bridge is 6772m long and14m wide, with two lanes. Two trains can leave at the same time. The main bridge on the river1577m, and the rest are approach bridges, which is the highest in China. On the railing of the main bridge, the highway approach bridge is in the form of a double-hole hyperbolic arch bridge with China characteristics.

1960 65438+1October 1968 The railway bridge was opened to traffic in September 65438, and the highway bridge was opened to traffic in February 65438. Wuhan Yangtze River Bridge is a dual-purpose bridge for railways and highways. The railway bridge is 6772 meters long and the highway bridge is 4588 meters long, and ships of 10,000 tons can pass under it. It is the second Yangtze River Bridge in Wuhan.

The main bridge of Wuhan Yangtze River Bridge in Jiang Zhong has 9 piers with a hole of 10, each pier is 80 meters high, and the bottom area of each pier is more than 400 square meters, which is larger than a basketball court. The highest pier is 85 meters high from the foundation to the top. The pier spacing is128m, and the other 9 holes are160m. At both ends of the main bridge, there are four bridge heads more than 70 meters high. The whole bridge is like Rainbow Kongling River, and the bedrock is buried 33-47 meters below the riverbed of the main bridge. The foundations of the nine piers are heavy concrete caisson, steel caisson with pipe column, floating reinforced concrete caisson and steel sheet pile cofferdam pipe column. There are 9 holes in the main bridge 10 reinforced beam with a span of160m. High-quality alloy steel bars are riveted and assembled on site, which is very spectacular. Especially at night, the floodlights of 1048 on the bridge railing are put together, 540 metal halogen lamps on the bridge pier illuminate the river as day, all the 150 pairs of magnolia lamps on the highway bridge are in full bloom, and 228 sodium lamps and large sculptures at the bridge head make the bridge cross the river like a string of night pearls. Whenever night falls, China's lanterns are put together.

5. Write a composition on the Yellow River. The Yellow River is the second largest river in China, and is also known as the cradle of China with the Yangtze River. Therefore, I want to scream: "Protect the Yellow River."

The Yellow River is the second largest river in China. Now, the Yellow River has been destroyed and is famous for its rich sediment. According to statistics, the annual sediment transport in the lower reaches of the Yellow River is 65.438+600 million tons, ranking first in the world, with an average sediment concentration of about 36 kilograms per cubic meter. The Yellow River is surging, and most of the quicksand on both sides of the Yellow River is brought into the sea. Therefore, due to the soft soil around the Yellow River, floods often occur. Therefore, it is necessary to control the Yellow River, restrain the flood of the Yellow River and discharge quicksand.

The sediment and water in the Yellow River have been mixed and condensed into mud, and the water has basically become turbid. It is very difficult to finish the task of dredging sand. Moreover, even if the sediment is discharged, as long as there is sediment around the Yellow River, the sediment will be continuously discharged into the Yellow River until there is no sediment around the Yellow River. So we need to harden the land, which requires two schemes. The first is to slow down the flow of the river, so that the sediment will not be washed into the Yellow River. Second, more trees should be planted around the Yellow River, which has three functions: first, it can protect the environment; Second, it can act as a levee; Third, the land can be hardened. In addition, factories around the Yellow River should be moved to other places quickly to avoid polluting the Yellow River water.

We grew up drinking the Yellow River water, and it pains us to watch the Yellow River mother grow old and thin day by day. Mother Yellow River endures human torture every day, drinking sewage discharged by human beings and eating human domestic garbage, but still irrigates farmland and nourishes everything of human beings. The Yellow River in my heart is tragic and unfortunate. I believe that the Yellow River will be able to restore its former heroism and become the pride of our nation again.

The Yellow River in my mind reminds me of you. It is so magnificent. It starts from the northern foot of Bayan Kara with endless glaciers, accepts thousands of streams and rivers along the way, and runs to the coast of the Yellow Sea with huge waves, like a golden steel dragon, lying across the vast land in northern China. Looking back, looking back, my thoughts unconsciously rushed to ancient times.

In that distant ancient time, the natural environment around you was so superior. At that time, your climate was warm and humid, the soil was fertile and soft, there were green mountains and green waters everywhere, and the scenery was beautiful.

There are countless kinds of animals and plants. In the primeval forest that covers the sky, tigers wear mang forests, wild elephants flock, eagles strike the sky and fish swim in shallow water.

Wildflowers from all over the mountains are blooming and colorful, like a colorful carpet, covering Shan Ye, just like a fairyland on earth and a paradise. With such unique natural conditions, you naturally gave birth to a long and splendid Chinese civilization.

In these five thousand years of ups and downs, how many heroic stories are staged around you. Qin Huang Hanwu, Wen Tao Wu Lue; Song zu, tong.

No matter what great achievements they have made, they all grew up drinking the water of the Yellow River, and the future can only be achieved by the water of the Yellow River. Poet Li Bai praised you with passionate and heroic poems: "You don't see how the water of the Yellow River moved out of heaven and entered the ocean, which is gone forever."

"The Yellow River with nine twists and turns, Wan Li sand, stormy waves, and heaven remains our neighbourhood." It serves to show that you are swallowing mountains and rivers and thundering.

Ah, the Yellow River, how many natural and spectacular scenery you have created: "The desert is lonely and the long river sets the yen". With the strength of thousands of troops, you shed the Wan Li River and crossed the Woye Ningxia Plain, forming the border between "Ningxia in Huang Hefu" and "Jiangnan" and a land of abundance.

In the ups and downs of more than 5,000 years, the war in the north and the millions of lions in the south fought on the land of the Central Plains. The Chinese nation has lived in the shadow of swords for nearly five thousand years.

One generation of civilization was subverted, and another generation of civilization appeared one after another. In this way, the Chinese nation has gradually grown.

With their infinite wisdom, Chinese children resist foreign aggression and are rarely bullied. You see all this in your eyes and remember it in your heart, just as you are used to the autumn moon and spring breeze.

However, in the late Qing Dynasty and the early Republic of China, full of flames and smoke, Chinese sons and daughters were bullied and killed by foreigners. Perhaps, in these thousands of years, you have never seen children in China shed so much blood and tears.

You growled, you growled like never before; You cut off the flow, and you have a cut off that you have never seen before. Looking at the two sides of the strait, Qingshan is still there; Looking up at the sky, a few rays of sunset red.

However, today you are full of holes and the wind and sand are rolling. Time and tide wait for no man, maybe time has the power to pass by, but you have great and powerful spiritual strength to inspire Chinese children.

Today, the Chinese nation, which has experienced thousands of years of storms, is moving forward at an unprecedented speed to the world. Ah, the Yellow River, you have selflessly bred the great Chinese nation, which can't be measured by economic value. The Chinese people will always be grateful to you.

I promise, when the desert becomes an oasis and the bare land becomes a green hill, that will be the day when your clear water will flow eastward again! The Yellow River in my heart is the great cradle for the survival and development of the Chinese nation. For thousands of years, the Yellow River Basin has been an important base for our Chinese nation to create civilization.

The indomitable momentum of the Yellow River is a vivid portrayal of our nation's spirit of self-improvement and vigorous progress. The Yellow River Basin is one of the birthplaces of the four ancient civilizations in the world.

The ancient Yellow River Basin, with humid climate, abundant water resources and fertile land, was the earliest area of economic and cultural development in China. As the center of political, economic and cultural development in past dynasties, the Yellow River Basin has a history of more than 3,000 years. Four of the seven ancient capitals in China, Xi, Luoyang, Kaifeng and Anyang, are all in the Yellow River Basin.

Our ancestors created a splendid culture here. From The Book of Songs to Tang Poetry and Song Poetry, from Historical Records to History as a Mirror, many immortal poems and chapters have been born in the Yellow River region, adding immortal brilliance to Chinese culture.

The Yellow River has inspired countless beautiful poems, which have been passed down through the ages and are still full of strong artistic charm. The Yellow River is also an unruly and troubled river, which was once called "the worry of China".

The flood of the Yellow River is recorded in the history books. During the more than 2,500 years from the pre-Qin period to the Kuomintang period, the lower reaches of the Yellow River flooded 1500 times and changed its course 26 times.

On average, there are two violations in three years.

6. Write an argumentative essay on the sinking of the Yangtze River with the fear of life as the topic. /kloc-More than 700 people, all women and children, were rescued after the Titanic sank more than 0/00 years ago. The captain and the first mate's sailors sank to the bottom of the sea with the ship.

More than a hundred years later, the ferry was in distress on the main road of the Yangtze River, and more than 400 people were killed, almost all of them were old people, women and children. The captain, engineer and crew abandoned the ship and fled at the first time, all wearing life jackets.

Three hours after the accident, the captain sent a rescue signal ... The most puzzling thing is that more than 400 fresh lives passed away in exchange for a series of "touches" and praises. The touching news of the Yangtze River rescue came round after round.

Let's take a closer look: of the 456 people on board, only 14 survived, of whom 7 swam ashore to call the police, 5 drifted to Yueyang and other places to be rescued, and only 2 were rescued from the Yangtze River shipwreck. 14 After the incident 13 Divers launched the first wave of rescue.

In other words: such a great rescue only saved two lives. And it's in warm summer, inland Yangtze River, not Arctic Ocean.

There were 97 Shanghainese in the sinking of the Yangtze River in China, but the street screens in Shanghai were celebrating the stock market's breakthrough of 5,000 points. At the same time, in Shibuya Street, which has nothing to do with it, this country is mourning the unfortunate people who sank in China with a big screen ... The gap between civilizations lies not in the economy, but in the conscience of human nature.

7. Yangtze River composition, Yangtze River.
