    The Turning of the Earth

    　　It seems to us that the earth stands quite still. But it is really moving all the time. It turns around a make-believe line through its centre. We call this make-believe line the earth's axis (地轴). The two ends of the earth's axis are called its poles. It makes the earth twenty-four hours travel around its axis once.

    　　We look at the sun and say it “rises” and travels across the sky, but the sun doesn't really do so. It is the turning of the earth which makes us feel as if the sun were moving across the sky. We can't see that the earth is moving because everything else on the earth is turning with us. As the earth turns around every twenty-four hours, first one half faces the sun and then the other half. When our half of the earth is facing the sun, we say it is day. When our half is away from the sun, we say it is night. It is the turning of the earth that, tells us when to go to bed and when to get up.

    A．It is a line that we can't believe.

    B．It's a line that we can't see.

    D．It's a line that we can make and believe.

    C．the earth is smaller than the sun

    D．Both A and B

    5．When do we have “day” and “night”?

    [　　]

    A．When the part of me earth where we live faces the sun, we have “day”, and when the part of the earth where we live turns away from the sun we have “night”.

    B．When the earth faces us we have “day”, and when the earth runs away from us we have “night”.

    C．When the part of the earth turns to the sun we have “night”, and when our part of the earth turns away from the sun we have “day”.

    　　What a beautiful day!

    　　The sun is shining and everything looks bright. Stand in tile sun. Can you feel the heat of the sun? The sun that gives the heat is very far away. It is hard to believe, but the sun is about one hundred and fifty million kilometers away. If a plane flew day and night without stopping, it would take nearly 18 years to get to the sun.

    　　The sun doesn't seem very big to us, but it's really very huge. One million balls as big as our earth could fit inside the sun. The sun looks small because it is so far away. If the sun were much nearer, our earth would be too hot to live on. If there were no sun, the earth would be so cold that nothing could live on it. Aren't we lucky to be just about the right distance away from the sun?

    　　The earth circles tile sun. It takes one year for the earth to go completely around. The earth spins around once every 24 hours. In the morning the sun seems to rise in the east. As the day goes on, the sun seems to travel across the sky. In the evening the sun seems to set in the west and then it is night. Almost every part of the earth turns from day to night during every 24 hours.

    　　The sun gives us light. It keeps us warm. It makes things grow. Plants, animals and people need the sun. The sun makes our earth beautiful. We could not live with out the sun.
