● Try to stay away from places with too much noise. If you have to go, wear earplugs. A pair of good earplugs can cut the noise by 30 decibels. ● When swimming, remember to put earplugs into your ears to stop water from getting in.

● Never put anything sharp into your ears. If you think you have too much earwax, ask your mum or dad to help you clean it out. Keep these things in mind! Then you won't be saying “WHAT? WHAT?" when you are older.

    There are some easy things you can do to protect(保护) the environment and the earth. Choose ideas from the list or come up with a few of your own.

    ●Plant flowers grass or trees.

●Whenever you visit a park or beach, take away what you bring there—-keep rubbish in a bag until you can put it in a dustbin.

    ●Turn off the lights, TV sets when you leave the room. This saves a lot of electricity.

    ●Turn off the tap when you brush your teeth. You can save some water by not letting it run. Also, use a glass cup instead of a paper cup because this saves paper.

    ●Keep the doors and windows closed in winter to keep warm air in.

    ●Give your old books and magazines to a library instead of throwing them away.

    ●Give your old clothes to poor children you know instead of throwing them away.

    ●Use both sides of paper.

    ●Stop pouring dirty water into the rivers or the lakes nearby.

    ●Encourage all your friends to do the same things you do to help protect the earth.

    You don't have to wait until Earth Day to do these things. Make every day Earth Day.

    If everyone makes a contribution (贡献)to protecting the environment, the world will become much more beautiful.

Why does the sky change colors?

    What is the sky? How high is it? What color is it? What birds can live above it? These questions are difficult to answer, aren'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 can'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, we'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 doesn'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.
