彩虹彩虹是一座桥，Rainbow is a bridge,牛郎织女如果登上它，If the Cowherd and the weaver get on it,一定会更加幸福。
It's bound to be happier.
彩虹是一座滑梯，Rainbow is a slide,小朋友们如果玩了它，If children play with it,一定会更加可爱。
It will be more lovely.
彩虹是一条跑道，Rainbow is a runway,刘翔哥哥如果跑了它，If brother Liu Xiang runs it,北京奥运会一定更加精彩。
The Beijing Olympic Games must be more exciting.
