Think of some good words about rainbows
An example of a good statement is as follows: Rainbows are a magical natural phenomenon. It is a beautiful scene produced by the refraction and reflection of the sun's rays in raindrops. Rainbows often appeared in the sky after rain and were known as the "crown of natural phenomena after rain". Rainbows are not only a beautiful natural landscape, but also an important scientific tool that can be used to detect the color and intensity of the sun's rays to help people understand the physical properties of the sun. The color changes and duration of rainbows can arouse people's interest and exploration, becoming an important element in many literary, artistic, and scientific works. There was also a pale outline around the rainbow called "Rain Arc", which was also a very beautiful natural phenomenon.
