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 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.
