Nowadays，along the Yangtze River，the third longest river in the world，a great construction project，the Three Gorges Dam is in progress.Once pleted in xx，it will be the largest and most powerful hydroelectric project in the world.Towering 610 feet high and stretching 1.3 miles wide，the dam will create a reservoir that extends nearly 400 miles upstream thus changing the original landscape of this region. 　　 The project has been under discussion in China since the idea of the dam was first put forward in 1919.The Three Gorges Dam is both a marvel of engineering and the greatest challenge its designers have ever faced.The Three Gorges Dam has been engineered to store over 5 trillion gallons(加侖)of water and to withstand(經(jīng)得起) an earthquake of 7.0 on the Richter scale(里氏級)．In addition, the government says the dam will control terrifying floods and provide electrical power to Chinas growing cities. Like Chinas Great Wall，it will be one of the few manmade structures that can be seen from space.The Chinese government and the dams engineers think of the project as a symbol of national pride. 【誘思導(dǎo)學(xué)】　 What do you think of the Three Gorges Dam project? 【答案】　 Students own answer.
