    My parents and I went to the park on last Sunday. There were lots of visitors stood in front of the ticket window. We waited for a long time and buy three tickets. In the Tiger Mountain of the park, I was too eager to see the fierce frightened animals that I quickened my steps through the crowd. Unfortunate, I got separated from my parents. I had hard time looking for him, but I had no luck. Wandering in the park, I felt alone without any companions. Worse still, I had no money, so I had to walk home, covered as much as 5 kilometers.
