What is the sky？ Where is it？ How bright is it？ What lies above it？ These questions are difficult to answer, aren’t they？

　　Is the sky blue？ The sky has no color. We know that there is air around the world. When planes fly, they need air to lift their wings. Planes can’t fly very high because the air gets thinner when they go up higher. If we go up about 1,200 kilometers from the earth, we’ll find no air there.

　　When we talk about the sky, we usually mean the atmosphere around the earth. It is like a very thick “cover” over the earth and keeps it warm. Without the “cover”, the earth would be a very cold place and nothing could live on it.

　　Looking up above us, you will see the blue sky with white clouds. It is usually light blue, but the sky would be dark blue if you go to the top of the highest mountains. And you will see fewer clouds between you and the sun.

　　And if you sit in a spaceship high above the earth, there is no air at all. The sky would be so dark that its color would be black.

　　Sometimes the sky doesn’t look blue. When the sun rises and falls, you will see red, orange, and other colors in the sky. These are the most beautiful moments of the day.

　　Now you may understand that we see colors because the air scatters (散射) the sunlight. Light travels through the air. Without air, there would be no light and no colors.

Chinese people call the Spring Festival“Nian”. But do you know that Nian
was once the name of a monster(妖怪)?
　　A long time ago, the monster Nian lived in the mountains. It ate
animals. But in winter, it could not find food. So it came to villages and
ate a lot of people. People were so afraid of Nian that they locked their
doors before evening came during the winter. One day, an old man came to a
village. He told people there that Nian was afraid of three things——the
color red, fire and noise. He told people to play drums and gongs, make
big fires and set off fireworks(放鞭炮)to make Nian go away.
　　On a moonless, cold night, Nian went to the village again. As soon as it
opened its big mouth, people made loud noises and made fires. Nian was
really afraid and ran away. wherever it went, there was noise and fire.
When Nian was tired and could not run anymore, people killed the monster.
　　After that, on the coldest day of winter, people beat drums and gongs,
and set off fireworks to celebrate the death of the monster of Nian. They
put up red lanterns and have a big dinner without sleeping during the
night.
　　In the morning people greet each other happily. So now we have the
Spring Festival.
