Last Saturday, Leo and his family went to the Space Museum. Leo is very interested in space. He was excited. In the Space Museum, they saw lots of pictures about space travel. There were many models. Leo saw a model of a spaceship. It was so cool. Leo couldn't take his eyes off it. He said, "I want to travel to Mars (火星)! I want to be a taikonaut!" The next day, Leo got a present from his father. It was a book about space travel.
