彩虹，見過很多次了。但每一次看到，都總有一份說不出的興奮，一種筆墨難以形容的驚嘆。
興奮，因為不是想看就能看到的，畢竟下雨而又有陽光的機會並不多；也不是願意看多久，它就會出現多久的，畢竟晴雨雲霧，誰能控制？它七彩繽紛，若隱若現，跨越萬里長空，既雄偉又壯麗，怎能不叫人驚嘆稱奇呢？
上中學時，物理老師告訴我，彩虹是由於陽光在雨點中的折射而形成的。不過，很奇怪，這樣的解釋竟沒有使我的激動稍減。原來科學針對的只是「如何」，而不是 「為何」，告訴人彩虹是怎樣出現的，卻不告訴人它為甚麼會出現。
於是，有人看見它，說一句自然現象，然後埋首於自己的工作，繼續他們的生活 - 那沒有彩虹的生活。
有人看見它，興奮驚嘆，剛才的暴雨狂風，已毫不在乎，因為彩虹叫他們看得更深、更遠。朋友，你呢？
Rainbow, which we have seen many times, but every time we see, it always gives us the excitement that words cannot tell, and the amazement that pens cannot describe.
We feel excited, because the rainbow may not be there every time when you want to see; after all the chances of raining with sunshine appear simultaneously are few; and how long it will appear cannot be expected as you wish. Sunny days or rainy days, cloudy days or misty days, who can control? It is colorful and splendid, sometimes appears indistinctly, sometimes appears clearly, travels thousands of miles across the sky, is both majestic and magnificent, how can people stop crying out for its wonderfulness and amazement!
In my high school days, my Physics teacher told me that the formation of rainbow is the result of refraction of the raindrops in the sun. However, it was strange that such an interpretation did not diminish my passion. What the science pinpoints 'how', not 'why'; telling people how the rainbow forms, but not why it forms .
Thus, some people see the rainbow and say that it is only a natural phenomenon, nothing special to them, and then engross back into their own work and life - the life without rainbow.
Some people see it , feel excited and admired. What's just happened - the heavy rain and strong wind, now they don't care. Because the rainbow leads them to look deeper and farther.
And how about you, my friends?
