    The sun, the moon and the stars are all in the sky. We can see the sun in the daytime(白天). We can see the moon and the stars at night.

    The sun is much bigger than the moon. It gives us light and heat(光和热).

    The moon looks bigger than the stars, because it is much nearer to the Earth. The light of the moon comes from the sun.

    The stars look smaller than the sun and the moon. But most of the stars are bigger than the sun. They look small because they are very far away from（远离) us.

    Every kind of animals has their own way to live well in winter. In winter, the weather gets colder and colder. There is snow on the ground. Some animals sleep all the winter. These animals eat plenty of food in autumn. They need little or no food when they sleep. Some birds fly to the south for winter. They go to a warmer place to look for food. Some animals get much food in autumn and keep it at home. They may grow new and thick fur in autumn, too. Then they can feel warmer. In winter some animals live in the trees or under the ground.
