What is really happening? You do not see through the glass of a mirror as you do through a window. The glass of a mirror has a silver coating on the back. The light from the sun or a bulb bounces (弹回)off you ,goes into the mirror ,and bounces straight back out to you again.
Mirrors have been used for thousands of years. The earliest were round pieces of shiny metal. Glass mirrors came late. The ancients thought that a mirror was magic. They did not understand how it worked. They thought they saw their spirits in a mirror and breaking a mirror brought bad luck.
Today mirrors have many uses .For example, they can make rooms look bigger and prettier. They also show us if our hair is combed(梳理) well and our faces are clean. On cars, buses and trucks, mirrors help drivers see traffic behind them. Mirrors are also used in telescopes(望远镜)and searchlights(探照灯).
Fun houses use mirrors. They make people look funny. Some mirrors are curved to make people seem short and round or tall and tin They make people laugh at themselves.
