Yesterday was Children's Day. Gary didn't go to school. He had a wonderful time with Ben and Susan. In the morning, they went to the zoo by underground. It took them about half an hour to get there. There was a dolphin show in the zoo. The dolphins were cute and smart. Gary and his friends loved the dolphins. After lunch, they walked to the science museum. They got to the museum at half past one. There was a robot show! They saw many different kinds of robots there. They learnt a lot and had much fun!
