    What is inside my head？

    Your head holds the most valuable part of your body in it—your brain. As you are reading, your eyes send pictures to your brain which makes meaning from what you see. Your brain helps you to remember and think, and makes sure your body is doing what it should do.

    What is my skin for？

    Your skin covers your body. In most parts of your body, the skin is just as thick as 0.5cm.If you cut your skin, it will have a quick cure(治愈)and stop viruses(病毒)from getting into your body. Your skin also helps you feel the heat and coldness of the environment around you. Hair grows from inside the skin. When you feel hot, extra heat comes out through your skin. As a result, your body temperature drops.

    How do I move？

    Muscles(肌肉) are found in most parts of your body. They work with your bones to help you move— whenever you cry or smile, eat or speak, walk or dance, etc.

    What does my heart do？

    Your heart is a very special muscle. It is a little bigger than your fist(拳头)and grows bigger as you do. If you place your hand on your heart, you will feel your heart beating which pushes blood to move around your body.

    For most of us, the days are divided into day and night. But for two months each winter in Northern Norway (挪威), it's dark for 20 hours a day. There is no sunrise or sunset because the sun never gets above the horizon (地平线) .

    Would you like to live in darkness for this long? It may seem difficult, but many people in Norway love the beautiful colors of these months.

    To the south are the red and gold colors of the horizon. To the north, the sky is a special blue. Even the moon and the stars look blue. In the towns, the lights in the streets shine like little yellow diamonds.

    People do need light to be healthy and happy. Since they don't have much daylight during this time of the year, they exercise and eat foods with vitamins (维生素) A and D, people usually get energy from being in the sun.

    And darkness doesn't stop people there from having a good time. Each winter, some people are skiing on hills and skating on ponds that are lit up. Others are going to film and music festivals And other people are spending time with friends in cafes and restaurants. Of course, not everyone is so active in the dark months. Many people are just going to sleep a little earlier until the sun returns in spring.
