(C)
①The Three Gorges Dam(三峡大坝)lying on the Yangtze River in Hubei Province, is one of the largest and most amazing engineering projects in the world. It stands proudly between the beautiful mountains of Xiling Gorge, showing the wisdom and hard work of the Chinese people.
②The Yangtze River, China’s longest river, often caused serious floods in the past, bring - ing disasters to millions of people. To solve this problem and create clean energy, the Chinese government decided to build a huge dam.
③People began to build the Three Gorges Dam in 1994. And it took over 12 years to com - plete. Thousands of workers used modern machines and technology to make this dream come true. They moved mountains, changed the river’s path (路径) to build the dam, which is about 2. 3 kilometers long and 185 meters high—as tall as a 60 - story building!
④Today, the dam plays a key role in China. It has greatly reduced flood risks, protecting cities and farmlands. The dam’s power stations produce clean electricity for millions of homes and factories, helping reduce air pollution. Its connected vessel system (连通器系统) helps ships pass. Ships enter a lock (水闸), and gates close. Water level inside the lock rises or falls to match the next section. When the water levels become the same, gates open, and the ship moves to the next lock.
⑤The Three Gorges Dam is not just a dam—it’s a symbol of China’s courage and creativity. Visitors from around the world come to see this modern wonder. Students learn about its scientific achievements and the spirit of teamwork behind it. The dam teaches us that with determination(决心), humans can overcome even the most difficult challenges of nature.
