The following are about modern wonders of the world.
The Suez Canal
More than 3, 000 years ago, a king of Egypt ordered that a river be built to connect the Mediterranean. Sea (地中海) and the Red Sea. This kind of man-made river is called a canal. However, ancient Egyptians did not keep this canal in use. As years passed, the sands of the great deserts of Egypt closed the small canal.
In 1859, Egyptian workers began rebuilding the canal. It was opened and named the Suez Canal on November I7th, 1869. Though closed several times because of war or political problems, the Suez Canal is still the fastest crossing from the Atlantic Ocean to the Indian Ocean today, saving shipping companies a great deal of time and money.
The Channel Tunnel
The great canal connects oceans. The next great wonder connects land. It is called the Channel Tunnel, or “Chunnel”, connecting Britain with France. The tunnel is 50 kilometers long, built about 45 meters below the earth under the English. Channel (海峡).
The work began in 1987 and it took seven years to finish. The cost was more than 13, 000 million dollars. The Chunnel opened In 1994.
Today, the Chunnel is very busy. High-speed trains carry cars, trucks and passengers from Britain to France and back again. The trains are famous for their smooth, quiet ride. The money paid for the trip is slowly paying for the huge cost.
The Three Gorges Darn
The Three Gorges Dam is perhaps the largest construction project on earth. The work began, in 1993.The Three Gorges Dam is built to produce power and control China’s Yangtze River. The completed dam produces large amounts of electric power.
Completed in 2009, the dam creates a huge lake about 632 square kilometers. Some critics say the dam harms the environment and damages historical areas. More than one million people had been resettled before the dam was finished. Chinese government officials say it will lead to increased economic development in cities near the dam, and the terrible floods caused by the Yangtze have become memories of the past.
