One of the greatest mysteries on Earth is the statues which stand on Easter Island. Easter

One of the greatest mysteries on Earth is the statues which stand on Easter Island. Easter Island, which was almost uninhabited when it was discovered on Easter Day in 1722 by a Dutch captain, is the most distant island in the world covered with hundreds of giant statues, each weighing several tons and some standing more than 30 feet tall.
Who built these statues and why and how did they get there? Nobody knows the answer for sure.
One theory suggests that Easter Island was first inhabited by Polynesians, who traveled thousands of miles in their canoes（独木舟）in 400 A.D. However, the ocean currents（洋流）which carried them there would not take them back, so that they could not leave.
The statues appear to have been made out of the top edge of the walls of a volcano on the island. Then, it may have been rolled or dragged down to the foot of the volcano(火山). Then, it was stood upright（直立）and ropes were tied around it, which was made to act as a pulley（滑轮）. Over a period of months, a statue could be walked for miles down to the ocean. Finally, it was placed in line with other statues, all of them looking towards the center of the island.
This process was difficult. If a statue fell over, it was too heavy to be pulled upright again, so the islanders went back and carved another statue.
The population of Easter Island must have reached 11,000. Later, the resources of the island were used up and people began fighting and eating each other. Work on the statues stopped and the statues were knocked over. When the first Europeans finally arrived on the island, most of these people had died out.
