The Yellow River, or Huanghe, is the second longest river in China. Tracing to a source high up the majestic Yagradagze mountain in the nation's far west, it loops north, bends south, and flows east for 5,464 km until it empties into the sea, draining a basin of 745,000 sq km, which nourishes 120 million people. This river carries lots of mud and sand thus it becomes yellow in colour. Millennia ago the Chinese civilization emerged from the central region of this basin.

精彩的三峡大坝英文导游词1 Good morning, ladies and Gentlemen, Welcome to China! Welcome to Hubei Province!
Today I am very pleased to show you Three Gorges of Yangtze River.
At first I’ll he a brief introduction of Yangtze River, the Yangtze River, the biggest river in China, the third longest in the World, starts with the Tuotuo River at the Roof of the World -Qinghai-Tibet Plateau, takes in countless rivers, and flows eastward across the interior of China. With an overall length of more than 6,300 kilometers, the Yangtze River, next only to the Amazon and the Nile, is the third biggest river in the world and is a cradle that breeds the ancient civilization of the Chinese nation.
When the Yangtze River reaches the eastern Sichuan Basin in southwest China, it cuts through the Wushan Mountain. Here the river course suddenly narrows and the waters become turbulent. Sheer cliffs and steep mountains rise on either side, creating one of nature's most fantastic sights. The Three Gorges---Qutang, wuxia and xiling----start just after Fengjie and end near Yichang, stretch about 200 kilometers. The Gorges vary from 300metres at their widest to less than 100 meters at their narrowest.
Qutang Gorge is the allest and shortest Gorge, but grandest of the three. The Yangtze River, mighty and rapid here is suddenly contained like "a thousand seas poured into one cup", as the Song Dynasty poet SU Tungpo described the spectacle. High on the both bank, at a place called Bellows Gorge, are a series of crevs. This area is said to he been the home of an ancient tribe whose custom was to place the coffins of their crevs, some containing bronze swords, armour and other artifacts, but the coffins are belid to date back as far as the Warring States Period (475bc----221BC)
Wu Gorge extends 40 kilometers along which the river snakes between based strange-shaped mountain peaks, each of which has a reputation based on a beautiful legend. The story of the "12 Peaks of Wushan goes like this: 12 nymphs once descended to enjoy themselves in the secular world. Finding how perilous Wushan Gorge was, they decided to stay there to protect ships. As time went by, they transformed themselves into 12 peaks. The Goddess Peak, the most graceful of the 12, is said to he been yaoji, the youngest daughter of the Queen mother of the Western Heen .Goddess Peak stands out from the other peaks on the northern bank to be the first to greet the morning sun and the last to bid it farewell, hence its another name, Viewing the glow Peak. Seen at a distance, it resembles the silhouette of a beautiful young lady.
Down stream from the zigzagging Wuxia Gorge is Xiling Gorge which stretches 78 kilometers eastward and the cliffs on either side rise to just over 900 meters. Xiling Gorge is awesome with its erous rapids, shoals, reefs, sharp turns, billowy whirlpools. The water at one point is so turbulent that it seems to be boiling during the flood season. Xiling Gorge in the east consists of sral all gorges. On the top of another is a rock that looks like a sword. On the crag of the north bank are two pieces of brown rock, which are named Bull's Liver and Horse' Lung, whose shape they take. Next does the Lantern Shadow Gorge, which has four rocks, resemble Monk Xuan Zang and his three disciples---Monkey, Piggy and Sandy in the classic Chinese aentures of the four on their way to India to obtain Buddhist scriptures.
Around the last bend of Xiling Gorge stretches a vast plain. The river suddenly becomes wide here. Trelers on the Yangtze cruise may also visit many sites of historical and scenic interest along the river banks including the ruined of baidi Town and Precious Stone Village.
Everyone knows that the Yangtze Gorges are changing since the well-known Three Gorges Dam Project is being built at Sabdouping, Yichang, Hubei Province. The dam is 181 meters in height. Its construction investment comes up to 203.9 billion , equals to 24.65 billion U.S. dollars. The installed power generation capacity is expected to be 18.2 million kilo watts. With the dam built, the flood in the Yangtze River valley will be controlled, nigation improved besides the economic benefits. Touri will be little affected. Many cultural and historical relics are now being removed to a higher ground before the rise of the water ll approaches.Ladies and Gentlemen, the time has gone very quickly and your trip is drawing to a close. It’s a pity that you cannot stay here any longer. Please allow me, then, take this opportunity to thank you for your cooperation and understanding, and if you come back in the future, I hope to see you again and be your guide again
精彩的三峡大坝英文导游词2 now we are on the way to three gorges dam, I will offer you some basic rmation about this giant project in aance. Speaking of three gorges dam, it is goes without saying that the three gorges dam is virtually subtlety associated with the number 3,why?I will give you the explanation .Because many of rmation about three gorges dam contains the number 3.Firstly, three gorges dam is located at sandouping town,38km away from Gezhouba dam which is situated at downstream.Secondly, it is esteemed that 20xx billion has been invested in construction. Thirdly,the project had experienced 17 years which divided into 3 phases. from 1993 to 1997 is the first period and this period is regarded as preparation period;from 1998 to 20xx is the second period and the last period indicates the year from 20xx to 20xx.After the project completed,the normal water lr has gone up to 175 meters and the strong capacity of reservoir amount to 393billion cubic meter. Due to the water ll rises, 430 thousand arable land has been submerge and 1.75 million immigrations he to search for new land to inhabit.
As i he mentioned,in order to construct three gorges dam, considerable number of immigrant quit their home and arable land also is deserved.Apart from this, the dam will brings other negative effect, for social aspect, on one hand, millions of people will be displaced, the government will take great pains to solve the problem that settle down the immigrant and assit them to find a new job.On the other hand,some culture heritage will disappear and under the water forr since the water lr rises,for natural aspect,building dam will alter the envirment,also does harm to precious animal such as Chinese sturgeon.
Every coin has two sides, it must be paid pr for the negative influences of three gorges dam, but the national congress insist maintain the decision of building three gorges dam because the aantage of building three gorges dam outweighs the disaantage of building three gorges dam. three gorges dam, not only bring us significant economic effect but also is beneficial for environment and society because it will play vital role in many fields, for instance, flood control,electricity nigation,touri,south to north water diversion,irragation,dlopment-oriented resettlement.especially, three gorges dam demonstrates remarkable contribution in 3 fields:
First field is power generation:the annual erage power of three gorges dam accounts up to 84.7 TWH. campared to the coal-fired power station with equivalent electricity generation,hyroelectric power is renewable and exhasible.besides that hydroelectric power is clean energy.three gorges power plant will decrease emission of 100 million tons of CO2,2 million tons of SO2.
Second field is nigation,the annual one-way nigation capacity of Yangtze at the dam will be upgraded from 10 million tons to 50 million tons.
third field is flood control,the effective flood control capacity reaches 22.15 billion cubic metres.the rare catastrophe of flood will be withstood by the dam thus 15million people and 1.5million hectare of farmland will be relid from flood threaten.
OK!we are approaching the scenic spot.today we will view three spots in total,at first steep(tangziling platform) we will get the chance to he a glimpse of the panorama of three gorges dam.second stop-the platform of 185 meters height,it offers us golden opportunity to witness the shiplift and zigui immgrant town.the third stop.memorial gardern supply vidio and photoes about three gorges dam that you may interested in.
Now we are arriving at first stop-tangziling,please bring you valuables and get off the bus
preliminarly,please follow me to three gorges project model house.In front of us,there is the layout of three gorges dam's model with the scale of 1:850.Look at main body of three gorges dam which has been painted white colour.The main body can be divided into 3 parts:spillway structures,powerhouse and building for nigation.The axial length of the dam is 2309.47meters and the height of the dam is 185meters,the spillway structures,consisting 22 overflow and 23deep overflow,is in the middle of the main body with the length of 483meters.The spillway world drain the sludge and coordinate the flood when needed.There are 32 turbine-generator units installed on the right and left hand of the spillway structure,each with installed capacity of 700mw.
the nigation building consis of double-line five stage shiplock and ship elevator.double-line five stage shiplock is 6442m in length and 300m in width,with two way and five stages.And it is diveded into 10 rooms,each room is 280 in length and 34m in width.the fall between upstream and downstream is 113m,suitable for 10 thousand tons ships and it will take almost 3 hour to pass through the lock.Therefore the ship elevator is designed for fast nigation for medium and all ship below 3000 tons.The elevator container is 120m in length and 18m in width and it only need 40 minutes for those ships to pass through the dam.the elevator near the platform 185 will be finished in 20xx.

The Three Gorges Dam project is one of the most controversial international river issues. The dam would cross the Yangtze River, which is a the third largest river in the world, at a point where the river is a mile wide. The 610 foot dam would create a 39 billion cubic meter reservoir that would stretch for 400 miles. 3 Not only is this the largest dam r built, it is the largest construction undertaking. Financial backing has come from many national and international sources, including United States companies. China has also sought outside engineering and construction consulting from companies including Caterpillar Construction Company.
A dam on the Yangtze River was first proed by Sun Yatsen in 19 for power generation pures. This prosoal nr came about because of economic and political strife. Many leaders dreamed of taming the Yangtze River. Life along the Yangtze River can be treacus because of the deadly flooding known to devastate cities and lives. 6
Most of the controversy involves the relocation of a million people who live in areas to be submerged, the potential loss of many archeological artifacts, and the environmental disruption the dam will cause. Dai Qing, a Chinese journalist wrote the book, Yangtze! Yangtze!, which protested the dam in 1989. The book was banned and Qing was imprisoned for 11 months. 5 This type of behior on the part of the Chinese government has made many skeptical about sible corruption in the project.
China has also recid much critici for the expensive and risky project. Many say that building aller dams along the river rather than one enormous dam would be more efficient. Some he n claimed the dam is being used as a monument to the success of sociali. 5.
Phillip Williams of the International Rivers Network says, "There is a grandiosity that appeals to a megalomaniac instinct that overrides not only economic considerations but sometimes n sound political judgment."
Completion dates are set for 2009 and by 2003 China should be able to start generating power for the nation
The Three Gorges Dam (Chinese: 长江三峡大坝) is a hydroelectric river dam that spans the Yangtze River in the town of Sandouping, located in the Yiling District of Yichang, in Hubei province, China. It is the world's largest electricity-generating plant of any kind.The dam body was completed in 2006. Except for a ship lift, all of the originally planned components of the project were completed on October 30, 2008 when the 26th generator was brought into commercial operation. Currently, it contains 26 completed generators in the shore power plant, each with a capacity of 700 MW. Six additional generators in the underground power plant are being installed and are not expected to become fully operational until around 2011. Coupling the dam's 32 main generators with 2 aller generators (50 MW each) to power the plant itself, the total electric generating capacity of the dam will ntually reach 22,500 MW. The project produces hydroelectricity, increases the river's nigation capacity, and reduces the potential for floods downstream by providing flood storage space. From completion until September 2009 the dam has generated 348.4 TWh of electricity, covering more than one third of its project cost.The project mament and the Chinese state regard the project as an historic engineering, social and economic success, with the design of state of the art large turbines, and a move toward the reduction of greenhouse gas emissions. Howr, the dam has also flooded archaeological and cultural sites and displaced some 1.3 million people, and is causing significant ecological changes, including an increased risk of landslides. The building of the dam has been a controversial topic both in China and abroad.希望帮到你啦~

The Three Gorges Dam is a hydroelectric dam that spans the Yangtze River by the town of Sandouping, located in Yiling District, Yichang, Hubei province, China. The Three Gorges Dam is the world's largest power station in terms of installed capacity (22,500 MW). In 2014 the dam generated 98.8 TWh of electricity, setting a new world record by 0.17 TWh previously held by the Iú Dam on the Brazil/Paraguay border in 2013 of 98.63.[4][5][6] But in 2015, the Iu power plant resumed the lead in annual worldwide production, producing 89.5 TWh, while production of Three Gorges was 87 TWh.[7][8][9]
Except for a ship lift, the dam project was completed and fully functional as of July 4, 2012,[10][11] when the last of the main water turbines in the underground plant began production. The ship lift was complete in December 2015.[12] Each main water turbine has a capacity of 700 MW.[13][14] The dam body was completed in 2006. Coupling the dam's 32 main turbines with two aller generators (50 MW each) to power the plant itself, the total electric generating capacity of the dam is 22,500 MW.[13][15][16]
As well as producing electricity, the dam is intended to increase the Yangtze River's shipping capacity and reduce the potential for floods downstream by providing flood storage space. The Chinese government regards the project as a historic engineering, social and economic success,[17] with the design of state-of-the-art large turbines,[18] and a move toward limiting greenhouse gas emissions.[19] Howr, the dam flooded archaeological and cultural sites and displaced some 1.3 million people, and is causing significant ecological changes, including an increased risk of landslides.[20] The dam has been a controversial topic both domestically and abroad.[21]
