When I lived in my hometown, I liked raining so much, because sometimes I could see the rainbow, it is so beautiful and attractive. I remembered the first time when I saw the rainbow. It was a stuffy afternoon, when I took a nap, I heard it rained, but there was sunshine in the sky. After an hour, the rain stopped. I walked out of my house and took a look at the sky, I saw a long colorful bridge in the sky. It appeared clearly, so close to me, it seemed that I could walk it to the sky. Now I live in the city, but I never see such beautiful rainbow again. The city’s buildings cover the sky.
