Three Popular Mysteries
Many people are interested in mysteries. Strange places and
things make us curious and also a little afraid. Have you heard
about the following three mysteries?
UNIT 10 Mysteries of the World
Bermuda Triangle
Many planes and ships have disappeared in the Bermuda
Triangle between Florida, Bermuda, and Puerto Rico. The most
famous story was about Flight 19. A group of five aircraft became
lost in the triangle and never came back. Some sources say more
than 200 planes and ships have been reported missing.
UNIT 10 Mysteries of the World
Easter Island
No one knows for certain who made or moved Easter Island’s
giant head statues. They are known for their large noses and strong
chins. There are about 800 statues there. Some believe they were
made by the Inca of Peru. Others think aliens created them.
Scientists say that Polynesians found the island, but the statues
are still a mystery.
UNIT 10 Mysteries of the World
Crop Circles
Crop circles usually appear in farmers’ fields. About 250
crop designs are created mysteriously around the world each
year. In recent years, scientists have found that some are like
DNA. Some think the crop circles are made by aliens. In 1991,
two Englishmen said they created the circles 15 years earlier.
But they couldn’t prove it. And people doubt they could make
the designs in one night.
