雨停以后，空气里还可能飘着许多细小水滴。 如果这时阳光从你的身后照来，前方的水滴就可能把光变成一条彩色的弧线。 彩虹不是挂在天空中的彩色物品，而是光和水滴一起形成的景象。
After the rain, tiny drops of water may still float in the air. If sunlight comes from behind you, the drops in front of you may turn the light into a colorful arc. A rainbow is not a colored object hanging in the sky. It is a pattern made by light and water drops.
