Near the Nile River stand the famous pyramids of Egypt,the oldest of the seven ancient wonders of the world.Nearly 5,000 years ago,he Egyptains built pyramids to keep the bodies of their kings and queens after their death.They built more than 90 pyramids.Among them,the Great Pyramid is the largest and most famous.
The Great Pyramid covers an area of about 53000 square metres.Each side of the base is 745 feet （227 metres)long,It used to be 481 feet(146.5 metres) high,but now it is only 449 feet (137 metres).The Great Pyramid is made up of over 2300000 blocks of stone,Most of the stones weigh about 2.5 tons each.Thousands of people worked very hard on the Pyramid for over 20 years.They built it without any machines and finally completed it in about 2566 BC.
Although the pyramids did not protect the bodies of the kings and queens,they have served to keep their names and stories alive to this day.一定要通,
