今天是星期六，是一个阳光灿烂的日子，爸爸妈妈带我去杭州的河坊街玩。
Today is Saturday. It's a sunny day. Mom and Dad take me to Hefang Street in Hangzhou.
河坊街上可真是热闹非凡！来来往往的人群川流不息，各式各样的手工艺品五花八门，令人眼花缭乱。我们边走边看，忽然看见在一个小摊位上围满了人，我赶紧冲上前去看个究竟，原来人们都围在那儿挑万花筒呢！我拿了一个画着京剧脸谱的万花筒，朝里面望了望，惊讶地看到万花筒里出现了变化多端的图案，我就拉着妈妈让她给我买了一个万花筒。
Hefang Street is really bustling! The flow of people came and went, and the variety of handicrafts was dazzling. As we walked, we saw that there were people around a small stall. I rushed forward to see what was going on. It turned out that people were all there to pick up kaleidoscope! I took a kaleidoscope with the face of Peking Opera and looked inside. I was surprised to see the varied patterns in the kaleidoscope. I took my mother and asked her to buy me a kaleidoscope.
回家后，我就开始研究万花筒为什么会出现这么变化多端的图案呢？我问爸爸妈妈，他们也说不出个原因来。于是，我上网查了查。原来，万花筒的秘密就在于光的反射，它的图案是靠玻璃镜子反射而成的。它是由三面镜子组成一个三棱镜，在一头放上一些各色玻璃碎片，这些碎片经过三面玻璃镜子的反射，便会出现对称的图案，看上去就像一朵朵盛开的花。只要不断地转动万花筒，玻璃碎片发生新的组合，就会有无穷的新图案和新花样。
When I got home, I began to study why the kaleidoscope was so changeable? I asked mom and Dad, and they couldn't explain why. So I checked it online. It turns out that the secret of kaleidoscope lies in the reflection of light. Its pattern is formed by the reflection of glass mirror. It consists of three mirrors to form a prism. Put some pieces of glass at one end. These pieces will be reflected by the three mirrors, and then symmetrical patterns will appear, which look like blooming flowers. As long as the kaleidoscope is continuously rotated, new combinations of glass fragments will take place, and there will be endless new patterns and patterns.
我终于知道了万花筒的秘密了，虽然万花筒的原理是那么简单，可是却能给我们带来无穷的乐趣。
I finally know the secret of kaleidoscope. Although the principle of kaleidoscope is so simple, it can bring us endless fun.
