天空一边下雨一边出太阳的时候，我就会很兴奋，因为我知道很快彩虹就会出现了

When the sky is raining with the sun coming out, I will be very excited because I know the rainbow will show up soon. I am always attracted by its beautiful colors. It hangs in the sky, like a great miracle. As it is not often to be seen, so when it shows up, people will be very happy to appreciate the beautiful scenery. 
天空一边下雨一边出太阳的时候，我就会很兴奋，因为我知道很快彩虹就会出现了。我总是被它美丽的颜色所吸引，挂在天空中，像一个伟大的奇迹。大家因为没有经常看到彩虹，所以当它出现时，都会很高兴去欣赏这美丽的风景。
