    WHY IS THE SUN IMPORTANT?

    　　The sun is a huge (巨大的), hot, bright star. It is important because without it there would be no life on Earth. The sun gives us light and heat(热).

    　　All living things need light and heat from the sun to live. Plants need light and heat to grow. They use the light from the sun to make food. We cannot make our own food, but plants can. All the food we eat comes from plants in a food chain (链) which starts with the sun. For example.

    　　Animals need sunlight, too. Just like us, their food comes from a food chain which begins with the sun and the plants.

    　　sun→leaf→caterpillar (毛虫)→bird

    　　sun→seaweed(海藻)→small fish→whale (鲸)

    　　Sunlight means we can see during the day. If there was no sun, it would be dark all the time. Even when the sky is cloudy, the sunlight is very strong and it shines (照耀) through the clouds.
