HAVE ALIENS VISITED US?
Many people have stories about seeing aliens. Here are two.
Judy Varns works for a group called the Mutual UFO Network. The purpose of this group is to research UFO sightings. Varns thinks a place called Area 51, in Nevada in the U.S., may be the best place on Earth to see UFOs. One day, she took some photos in the area and saw something she thinks is a UFO. "We saw this little disk-shaped thing in our photos. It's kind of exciting," she says.
Pat Travis lives near Area 51. One night, she saw a strange light in the sky. The light's movements were very unusual. Travis saw the lights move sideways and up and down. She saw them make many strange moves. Travis thinks it was a UFO.
Secrets of Area 51
Some people think Area 51 is where the U.S. Air Force keeps secrets, like UFOs that came to Earth and the aliens inside them. But really, Area 51 is a place the U.S. Air Force uses to test new technology, such as new kinds of aircraft.
James McGaha is a pilot who flew airplanes at Area 51. "There is absolutely no UFO activity at Area 51," he says. "No flying saucers, no live aliens, no dead aliens."
So what did Varns and Travis see? Bill Fox worked at Area 51, too. He thinks he knows the answer. "We did build some strange-looking airplanes," he says. "I could see why some people would think they were UFOs."
So are UFOs real? You'll have to decide for yourself. But if you do visit Nevada, keep your eyes on the skies!
What is the main idea of the second paragraph?




A.Pat Travis lives near Area 51.
B.Pat Travis thinks she saw a UFO.
C.Pat Travis has seen many unusual things.
D.Pat Travis usually saw a strange light in the sky.

TREASURE SHIP
On a beach along the Skeleton Coast, the sand is filled with diamonds. But in April 2008, workers found something very different: a piece of lost history—a shipwreck and its treasure.
The story began when a worker from the nearby diamond mines found a piece of metal on the beach. It was a piece of copper. Soon, they found more copper and many gold coins. The workers then found that these came from the remains of a large ship. The shipwreck was the real treasure.
Archeologists studied the shipwreck. They thought the ship probably came from Portugal about 500 years before. However, it was difficult to find information about it. In 1775, many maps and books about the ships of the time were lost in a fire in Lisbon. "That left a big hole in our history,” says Portuguese archeologist Alexandre Monteiro.
Finally, Monteiro found out that a group of ships left Lisbon for India in 1533. One of them, the Bom Jesus, carried 300 people and a large amount of treasure. The Portuguese sailors planned to use the treasure to buy expensive Indian spices. Archeologists now believe the wreck might be the Bom Jesus. This is because many of the gold coins found were Spanish. Monteiro found an old letter in the Spanish royal archives. The letter said that Spain gave Portugal money for the trip. Two thousand Spanish coins were put on the Bom Jesus. This could explain why so many Spanish coins were found in a Portuguese shipwreck.
So what happened to the ship? The Bom Jesus probably got lost in a storm. Then it smashed into rocks near the coast and sank. There were few human bones found, so the sailors were probably able to get off the ship. But even if they swam onto the beach, they would have found themselves in a strange, distant land. They had no way to get home. They might as well have been on Mars. To this day, no one knows what happened to them.
