The beginning and end of adventure composition

At noon today, the weather is sultry and there is no wind in the air. I guessed it would rain, so I sat on the windowsill and watched. Gradually, the sky was overcast and gray, and the earth was dark. "Boom-..." There was light in the thick clouds in the sky, and within a few seconds, deafening thunder sounded. After a while, rain suddenly fell from the sky. It's raining harder and harder. From the original size of soybeans to the present, it is like a clear spring, and the glass windows are also trembling "bare". A few hours later, the rain gradually tired underground, turned into a small mung bean, turned into cow hair ... The rain stopped, and I went out, and the flowers and trees seemed to have a good bath. Green is greener and red is redder. The sunset came out and a rainbow appeared in the east. See the rainbow after the storm!
