    First of all, it's a myth that no two snowflakes(雪花)are the same.  In 1988, a scientist found two exact same snow crystals(晶体)that had both formed in a snow storm in Wisconsin, USA.

Since then scientists have come to learn that snowflakes can only form into 35 different shapes. Although scientists are also not sure why exactly the various shapes of snowflake form, they have confirmed(确定)eight main shapes, with each of these eight shapes having several different variations(变化).

Second biggest myth, snow isn't white. It's actually colorless. Snow is made up of very small pieces of ice, and ice is translucent(半透明的), which means that light does not pass through it easily, but rather it gets reflected(反射).

When light hits a snowflake, it gets reflected back from the snowflake's many surfaces, often bouncing(弹跳)between these surfaces, and because of this that light is reflected back to our eyes as the color white. This is why, when we have a close look at a snowflake, it always looks clear, yet in reality appears as white.
