Our body makes melanin to protect our skin from the sun. People with more melanin are darker and those with less are lighter. People in hot areas developed (生长) more melanin because dark skin helped protect against the sun and skin cancer. In colder countries, people developed lighter skin because they did not face the same kind of pressure to protect themselves from the sun. If your parents came from sunny places, you were born with more melanin and darker skin. If your parents came from less sunny places, you were born with less melanin and lighter skin.Put a bandage around your finger on a sunny day. Take it off a few days later. Did that part of your finger make any melanin? No! The bandage blocked the sun from the skin. When sunlight hits your skin, melanin comes to protect it, and gives you a tan.Task 1Tick(√) or cross(×).( ) 1. Darker-skinned people have more melanin than lighter- skinned people.( ) 2.

When sunlight touches the drop of water, the light scatters (散开） and we see all the colours of the rainbow.Light from the sun colours our world. Light can bounce (反射),scatter (散开), or be absorbed (被吸收). Light is made up from the colours of the rainbow. We see sunlight as white, so when light bounces, it comes back to us the same colour —white. When light is absorbed, it goes away and we see darkness. We see many different colours when light is scattered.The colours of sunlight are: red, orange, yellow, green, blue, indigo, and violet.We can make a rainbow with water and sunlight.Can you read?W a t e r g la s s me t h o d1.
