【答案解析】Sweeping down from the Qinghai-Tibet Plateau for about a thousand miles on a winding course, the mighty Yangtse River, with overpowering, irresistible force, cleaves passage in the middle reaches through a gap in the Wu Mountains that lies athwart its course, cutting the towering mountain range in two and then rushing down east to the sea, where the mighty river and the towering mountain range intersect, almost at fight angles. The Wu Mountains stands across the border between Chuan and E in the direction from northeast to southwest. The high and steep mountain peaks glare down on the turbulent waters of the Yangtse below from their precipitous heights, presenting a most majestic and awe-inspiring look, while the river, forcing its way down the narrow gorges between high and steep rocky peaks, roars and booms in uncontrollable anger. This section of the Yangtse River is one of the most famous natural wonders in the world. Today, the Chinese are gradually bringing to fruition their hopes of harnessing the mighty Yangtse. To the west of the City of Yichang not far downstream from the Three Gorges, the largest water conservancy project up-to-date in China, the Gezhouba Dam has been completed together with a large-scale power station which is now providing electrical power to the towns and countryside along the Yangtse River. On the banks along the Three Gorges there are now not only fields and orchards here and there but also an array of factories. On December 14, 1994, the Three Gorges, the largest water conservancy project in the world nowadays, began formally to be constructed, and it will wholly be finished in 2009. The region is not only famous for an important base of industrial and agricultural production, but also famous for irresistible scenic attractions in China.
