Last weekend John went camping with his parents and his sister, Mary. They took a tent, sleeping bags, water and food. They arrived at the campsite at about three on Saturday afternoon. First they went cycling along thelake for more than two hours. When it was getting dark, they returned and began to enjoy their dinner. Everything tasted delicious.

    Soon it was time to put up the tent. John helped Dad pull the tent out of the bag. Then, they found there were no poles (杆子) to hold it up.

    "Oh," cried John. "I forgot to bring the poles. What could we do?"

    Dad looked up at the sky. There were many stars in the sky. The night was clear and the air was warm.

    "It's OK," Dad said. "We don't even need a tent." He put the sleeping bags on the ground.

    They slept well that night. The sun was shining on them when they woke up the next morning.

    "It is my best camping trip," said John.

Sam: Goodbye!

There are many colors in nature. But do you think that a color has weight? Let's do a test.

First, put two objects with the {#blank#}1{#/blank#} weight into two boxes. Then cover the boxes. Third, wrap (包裹) one box with a red piece of paper, the other with white. Now hold the boxes {#blank#}2{#/blank#} your hand one by one. Which one is {#blank#}3{#/blank#} ? It is certain that you will think the red one is heavier. Why do you think so? A scientist did many {#blank#}4{#/blank#} and found that different colors have different weights in a man's mind.

Also, scientists say that people accept the colors they like, and {#blank#}5{#/blank#} the colors they hate. So your body and mind will be {#blank#}6{#/blank#} by using the colors you like. Or you'll be nervous {#blank#}7{#/blank#} even get ill. For example, you {#blank#}8{#/blank#} blue and hate red. If you stay in a room with red windows and wallpaper for two hours, you'll feel you have been there for {#blank#}9{#/blank#} hours. But if the room is blue, you'll feel you have been there for only an hour, And, if a person walks {#blank#}10{#/blank#} of a blue room and into a red room, his temperature will rise. That means our body temperature will change with different colors.

Why does the Sky Change Colours?

What is the sky? How high is it? What colour is it? What birds can live above it? These questions are difficult to answer, aren't they?

In fact, the sky has no colour. 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 (机翼). Planes can't fly very high. That's 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 1,000 kilometres 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 colour will 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 or falls, you will see red, orange, and other colours in the sky. Such are the most beautiful moments of the day.

Who can see the colours of the sky high above the earth? The astronauts! They can see those beautiful colours of the sky from 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 will be that dark and its colour will be black.

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