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.

Food or friends? Lip salve (润唇膏) or iPod? What is the most important thing in the US teenagers’ lives today? Let’s take a look.

Some find that they can’t do without people.

“My biggest need is my friends. Without them, I wouldn’t do much,” said Adrian Fernandez, a 14-year-old boy.

With others, food always comes first.

“I do not think that I could live without chili con carne (辣子肉丁). I eat it every day. And if I didn’t have it, it’s all I would think about,” said Max Wu, an 8th-grade boy.

Sometimes, the things teenagers can’t do without are strange.

Take 14-year-old girl Hannah Sacchini for example. “I cannot live without lip salve, especially in winter,” said Hannah Sacchini. “I go mad if my lips get dry.”

Of course, today everybody uses mobile phones and computers. Some teens can’t live without these high-tech (高科技的) things.

Justin Beck, a 15-year-old boy, feels like this: “I would not be able to live without my iPod. I use it for so many different things. I always have it with me,” he said.

So, now we know the things US kids really must have. What about you and your classmates? What can’t you live without?
