What is the sky? How high is it? What color is it? What birds can live above it? These questions are difficult to answer, aren39。t they? In fact, the sky has no color. Then why does the sky look blue? We know that there is air around the world. When planes fly, they need air to lift their wings. Planes can39。t fly very high. That is because the air gets thinner when they go higher. The same will happen to us if we go high enough. If we go up about 1, 200 kilometers from the earth, we39。ll find no air there. Some birds can fly into the sky as high as a plane, but they cannot fly or live without air. Looking up above us, you will see the blue sky with white clouds. It is usually light blue. The color would be bluer when you see on the top of a high mountain. And you will see fewer clouds in the sky between you and the sun. Sometimes the sky doesn39。t look blue. When the sun rises and falls, you will see red, orange, and other colors in the sky. Such are the most beautiful moments of the day. Who can see the colors of the sky high above the earth? The astronauts! They can see those beautiful colors of the sky from the outer space. However, before flying into outer space, they sit in a spaceship high above the earth, and there is no air at all. The sky would be that dark and its color would be black. Now you may understand that we see colors because the air scatters（使散射） the sunlight. light travels through the air. Without air, there would be no light or colors. （1）Planes can39。t fly as high as possible because_________. A.the sky is blueB.the wings are heavierC.the sky has no colorD.the air bees thinner（2）When you stand on the top of a high mountain, you will see_________.
