The First Rainbow Tunnel
Today, when I read the newspaper, I saw the interesting news, it is said that the first rainbow tunnel has been built in our country. I have seen many tunnels when I went out by bus, every time when the bus went through the tunnel, it was so dark, I felt not good, it just like I went to another gloomy space. But the rainbow tunnel is very different, it is so colorful, it looks so comfortable. It is so sweet for the workers to build such lovely tunnel, it brings the travelers good mood, the workers are so considerate, they deserve the big praise. I think if more rainbow tunnels are built, the travelers will be less tired in their journey.
