Sun is the most powerful thing in the solar system. It’s the energy of all the animals, plants, and humans. However, the sunset always makes me feel sentimental.
Why does the sky’s color is blue? Why does the sun turn red when it’s setting? It’s because of Refraction. Sunlight contains the colors red, orange, yellow, green, blue, indigo and purple. In vacuum, the seven-color lights’ speeds are the same but they change in different medium. So when the sunlight gets into the aerosphere from space, the red light, which is the fastest, will curve slower than other’s. That’s why the sky is blue, and the sunset is red. The scientific knowledge that was concealed in the sun, were one of the reasons why I loved the sun. If these happen at all time, I will be as sharp as a tack.
“To see the sun, for all his glory, buried by the coming night.” Two weeks ago, I studied hard day and night, so I passed the entire routine test until the monthly exam. I got a fever up to 39 ℃. Although I had the highest score in my class, I failed. The score, what I expected to get was higher than the score, what I got. I disappointed myself. Beautiful things always appear in the twinkling of an eye.
I apologized the mistakes of this text, and please helped me to correct it or gave me some proposal. Thanks a lot.
