Mike: ..So, we can look forward to warmer temperature. It’ll be a good weekend for the beach. Over to you, Alexa.
Alexa: Thank you for that weather report, Mike. And finally, this story just in. … We have a report that a local man, Nick Brown, saw some strange lights. He was driving home at about 10 p.m. He said the lights were bright and they moved across the sky. He stopped at a gas station and talked to a police officer about the lights. The police officer had seen the lights, too.
M : Hmmm,… that’s strange story. What happened next?
A : Well, Mr Brown took some pictures, but there was no film in his camera. Finally, he called his wife on his cell phone. But by that time, the lights were gone.
M : Well, I know that there is a legend around here about mysterious lights … a lot of local people have seen the lights. It’s starting to seem like those lights really exist.. What do you think, Alexa?
A :I don’t believe it. I think it’s some kind of hoax!

It was raining heavily. I couldn’t see clearly. I drove slowly. Suddenly, I saw a young was dressed neatly and standing in the middle of the road. I was surprised! Somehow, I stopped the car quickly. “What are you doing?” I asked. She looked at me strangely but didn’t answer. “Are you OK?” I asked. “I’m fine,” she answered. Then she smiled happily and walked away quietly. Nervously, I drove to my hotel and checked in. I told the clerk about the little girl. “Do you know her?” I asked. “Oh yes,” he said calmly. “That’s Mary Anne. She died five years ago on that road. It was a car accident during a rainstorm.”

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 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 in1908, 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 electrici
ty. 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.

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 coundn’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.

I had an amazing dream last night. I was standing outside of an strange big house. The house was painted pink, a very rare color for a house. It had a lot of big windows, either round or rectangular. The house had large square pillars and twisted columns. I was thinking there mus
t be a big living room, several bedrooms, a kitchen, and a guest room in such a big house. I was wondering whose house this was when I suddenly heard a voice from somewhere: “My lord, welcome home.” Wow, this was my dream house.
I went inside and walked into my living room. It was spacious. There were sofas, a table, a big-screen TV, and a stereo system. It was pretty cool. All my best friends were there, too. But somehow they didn’t speak, didn’t smaile, and didn’t even move. And then suddenly they all disappeared. I was scared. What a terrible dream.
I then went to the kitchen. It was also spacious. There were all kinds of kitchen equipment, including a gas stove, a refrigerator, and an oven. There also many electric appliances, such as a microwave oven, an electric mixer, and a food processor. I liked the food processor the most, which made life much easier. There was also a dining table in the middle of the room. The whole family was sitting around the table, waiting for the meal to be served. But the fridge was empty, and the gas stove didn’t work. And there was no electricity at all for the microwave oven and the the food processor. The hungry kids started to cry. I was in despair. And then suddenly I woke up.

Sleep and dreams
Scientists know that the brain is very active when a person is sleeping. There are five stages, or parts, of sleep. Stage 1 starts after you fall asleep. If there is a noise or a bright light, you wake up very easily. In stage 2, your brain waves are very slow. In stage 3 and 4, you are in deep sleep. It’s very difficult to wake up then. Your body rests and grows during these stages. Stage 5 is when you dream. Your eyes move a lot, and your brain waves are fast. This stage of sleep is very important for your memory. After stage 5, you wake up a little, and then stage 1 starts again. We go through the five stages of sleep four or five times every night, so we have many dreams in one night.
How much sleep do you need? The answer depends on your age. Babies should sleep 15 to 16 hours every day. Children and teenagers need 9 or 10 hpurs of sleep, but older people only need 6 to 8 hours. If you sleep for only four hours one night, you may just feel tired the next day. But many nights of bad sleep can be bad for your health. People who don’t get enough sleep get sick more often. And sleep is very important for learning. It’s one reason why students should go to bed early.

The meaning of dreams
For centuries, people have asked: why do we dream? What do our dreams mean? Today, science doesn’t have definite answers to these questions, but we do know some things about dreams. First, we all dream, often 4 to 5 times a night. Second, we don’t usually remember most of our dreams. And finally, when we dream, our brains are very active.
Thousands of years ago, people began to study dreams. In many cultures, people believed dreams were messages f
rom spirits or gods. Later, the ancient Greeks and Romans had a new idea: Dreams come from a person’s mind. Doctors studied dreams to help sick or worried people.
I n the past, some cultures used dreams to predict the future. They thought dreams could help a person choose a husband or wife, guess a baby’s birthday, or starts a business. IN some places, this practice is still common.
Today, scientists think dreams are about our thoughts and feelings. Our minds send us messages about our lives. Unfortunately, many messages are often strange or confusing. People wake up and think: What did that dream mean?
So, how can you understand the messages in your dreams? Think about the events in the dream. What do they say about your life ? For example, one common dream is about flying. Sometimes this dream means you feel free or want freedom. Other times it means you feel afraid. What do your dreams tell you about your life?
