The Mysteries of Nazca
In the desert of Peru, 300kilometers from Lima, one of the most unusual artworks in the world hasmystified (迷惑) people for decades. ______ (46) But from high above, these marks arehuge images of birds, fish, seashells, all beautifully carved into the earth.
The Nazca lines are sodifficult to see from the ground that they weren&39;t discovered until the 1930s,when pilots spotted them while flying over the area. In all, there are about 70different human and animal figures on the plain, along with 900 triangles,circles, and lines.
Researchers have figured outthat the lines are at least l, 500 years old, but their purpose is still amystery.______(47) However, it would probably be very tricky to land aspaceship in the middle of pictures of dogs and monkeys.
In the 1940s, an Americanexplorer named Paul Kosok suggested that the drawings are a chronicle –(记录) of the movement ofthe stars and planets. _____ (48) Later, an astronomer tested his theo-ry witha computer, but he couldn&39;t find any relation between the lines and movementsin space.
Another explanation is thatthe lines may have been made for religious reasons. British researcher TonyMorrison investigated the customs of people in the Andes Mountainand learned that they some-times pray by the side of the road. It&39;s possiblethat in the past, the lines of Nazca were created for a similarpurpose.____(49) But the local people have never constructed anything this big.
Recently, two otherscientists, David Johnson and Steve Mabee, have speculated that lines couldhave been related to water. Nazca is one of the driest places in the world andreceives only 50px of rain every year. While Johnson was searching for ancientwater sources in the area, he noticed that some waterways built ancient peoplewere connected with the lines. Johnson believes that the Nazca lines are agiant map of the underground water in the area. ____ (50)
