2. Pale red, orange, yellow, green, blue and purple spread in a straight line, who dances with color training in the sky. Modernity-Mao Zedong's Mahathir Bodhisattva, translated: There are seven colors of rainbows hanging in the sky. Who is dancing in the air with a rainbow in his hand?
3, the reflection and refraction of light phenomenon-a round of setting sun in the water, half river rustling and half river red, poor September third night, like a pearl like a moon like a bow. Tang Dynasty-Bai Juyi's Ode to the Mujiang River, translated: the setting sun reflects the river, and the glow is shining; Half of the river is dark blue and the other half is red. The loveliest thing is the night on the third day of September, with dew like beads and crescent like a bow.
4, molecular thermal movement-the fragrance of flowers is warm, and the magpies sound through the trees to celebrate the new sunny. Song-Lu You's book "Happiness in the Village", translated: the flowers are fragrant, you know the weather is warm; The weather was fine, and the magpie's cry came through the Woods.
5, inertia-the ship broke down in the middle of the river late, and it was too late to pull back from the cliff. The dynasty is unknown-the author is unknown. If the ship wants to stop in the middle of the river, it must break down ahead of time. It will be too late to break down in the middle of the river. When it reaches the cliff, the horse will stop and move on.
