Who built these statues and why and how did they get there? Nobody knows the answer for sure，but many are trying to find it out.It has even been suggested that space aliens may have played a role regarding these giant statues.There are also other theories about it. One theory suggests that Easter Island was inhabited by Polynesian sailors，who traveled thousands of miles in their canoes，guided by the stars，the color of sky and the sun，the shapes of clouds，the birds making flights out to sea seeking food.The Polynesians first arrived on the island in 400 A．D.However，the ocean currents which carried them there would not take them back.They were trapped and could not leave. The Easter Islanders had their own system of writing，different from any other in the world.No other Pacific Islanders knew how to write，and the American Indians did not know how to write either.Who taught the Easter Islanders how to write，or did they develop their own system? Remember that writing was first invented in Asia. Easter Island and the statues that exist there suggested the influence of alien from other planets.Easter Island continues to be one of the world's greatest unexplained mysteries. 1．statue n． 雕像；塑像 2．regarding prep. 关于；至于 3．inhabit v. 居住于；占据；栖息 4．canoe n. 独木舟 5．current n. 趋势；(水、气、电)流 Why couldn't Polynesian sailors leave the island according to the passage? ________________________________________________________________ ________________________________________________________________ 【答案】 Because the ocean currents which carried them there would not take them back.
