At night, when I look up at the sky, I always imagine what it is like on the moon. If I can stay on the moon, the first thing I want to do is find the footprints of Neil Armstrong. He is the hero in my heart. Then I want to find out if there are beautiful mountains, rivers or parks on the moon. What’s more, I will try the food on the moon. Do I need a bed to sleep on the moon? I really want to know. The trip is sure to be wonderful. I hope I can really have the chance one day.
