Light and shadow（影子）are friends. They usually go
together. We receive light every day. At the same time, we produce shadow.
Light cannot shine through you. Your body
stops it from passing. There is a dark spot on the ground next to you. The
light cannot reach the dark spot. This is your shadow.
At noon the Sun shines over your head. Your
body stops very little light from reaching the ground.
We love light, especially sunlight. Without
sunlight, life on the Earth is impossible. Most of us like to stand in the shadow
of a tree in summer. But some people are afraid of their own shadow at night.
They do not want to walk in a dark street. They do not want to see the shadow
either. But still light and shadow usually go together.
