yes,” he said calmly. “That’s Mary Anne. She died five years ago on that road. It was a car accident during a rainstorm.” Listening 4
A. The Tunguska mystery
It was early morning, June 30, 1908, in eastern Russia. Suddenly, a terrible explosion rocked the forest in Tunguska. People fell to the ground, and all the trees for 2000 square kilometers were knocked down. People heard the explosion 800 kilometers away, and the fire burned for many weeks.
B. What caused this terrible explosion? A century later, scientists are still trying to find the answer. Here are some possible explanations.
1. An asteroid: Asteroids are very large pieces of rock that goes around in space and sometimes hit the planet. They can cause lots of damage. Some of them weigh as much as 100, 00 tons. If an asteroid hit the earth, it would cause a huge explosion.
2. A comet: Comets are giant balls of gas, ice, and rock with long tails. They travel through space in a regular pattern. Encke’s Comet was near Earth in 1908, and it’s possible that a part of it broke off and hit the earth.
3. An UFO accident: Some people believe that a spaceship crashed into the ground in Siberia and its engine exploded.
4. An extraterrestrials might have wanted to destroy the earth, so they aimed their weapons at Earth and set fire to the forest.
5. A scientific experiment: Another idea is that scientists made a mistake during an experiment with electricity. A man named Nikola Tesla tried to build a “supergun” that used electricity. Maybe it was a test of his gun and it didn’t work correctly.
Listening 5 The Marfa mystery lights
Q. Where is Marfa and what exactly is it famous for?
A. Marfa is a small town in west Texas in the United States. It’s famous for the “Marfa mystery lights”
Q. What are the mystery lights exactly?
A. No one knows for sure. There are many different ideas about that. Q. Can you describe them?
A. That’s a difficult question. Different people see different lights. They are not always the same. I can say that they appear after sunset in the sky. They dance mysteriously in air and vanish. Then they suddenly reappear.
Q. Some people say they are car headlights. Do you think so?
A. No. I don’t. A man first saw the mystery lights over 100 years ago. The man was Robert Ellison and the year was 1883. Of course we didn’t have cars in 1883.
Q. What do you think causes the lights?
A. There are many theories. The Native Americans thought the lights were stars falling to Earth. Some people think uranium gas causes the lights. Other people suggest that ball lightning does it. Ball lightning is lightning in the shape of circle. It often appears just after a rainstorm. Q What are some of the weirdest ideas about the lights?
A. Well, some people call them “ghost lights”. They think ghosts do it. That’s the strangest idea. Some say they are UFOs. I don’t think so. Q. What do the experts say?
A. They can’t figure it out. Some engineers even came from Japan one time. They studied the lights, but couldn’t solve the mystery. Q. Are the local people scared?
A. No, actually, they aren’t. They like the lights. And every year in early September there is a big town festival to celebrate the mystery lights.
