Look into the mirror and what do you see? You see yourself. But when you move. you do everything backward(相反地)in the mirror! If you wave your left hand, your right hand waves in the mirror. If you wink your right eye, your left eye, your left eye winks(眨). Try to read a page in the mirror .The words will be backwards.
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.

(答案→)B 解析：文章讲的是镜子的产生及其它发展的过程，并讲到了镜子的作用。1. B 从you do everything backward(相反地)in the mirror可知你做的动作与你的镜子里看到是相反的，所以你wave your right hand看到的就是your left hand wave，选B。2. A 细节题的考查。从Mirrors have been used for thousands of years可知镜子很久前就出现了，选A。从The earliest were round pieces of shiny metal可知B答案错误，不是开始时镜子就是玻璃做的；C答案也错误，现在流行的镜子是玻璃做的；而从They did not understand how it worked知道古代人们并不知道镜子如何发生作用，故D也错，选A。3. A 我们可以定位到第二段，从下面They thought they saw their spirits in a mirror可知这就是他们认为的原因，故选A。4. D 首先找到这个单词的位置在最后一段，再看后面make people seem short and round or tall and tin可知让高的变成矮的，故是弯曲变形的意思，选D。

这下我知道了
