The Clouds

Clouds walk in the sky， Sometimes low, sometimes high， In the dark night， In the warm and brilliant sunshine.Ah! I really want to know， Are you going to do a lot of good things? 
 Yes， We are busy day and night， Guard the earth in our way. We are the messenger of raindrops， Watering grass flowers and armor. On a hot summer day On a hot summer day On a hot summer day， We protect you from strong light.
