    On Sunday morning, Jack was painting in the study while the phone rang. He hurried to the phone. He was his workmate, Mike. While they were chatting on the phone, but his little son knocked over painting. Jack rushed back to the study. The painting was on a mess and the baby was crying. He quickly cleared the mess, comforting the baby and then took him out. To his surprises, his wife came back from shopping ahead of the usually time. He was rather embarrassing. He told his wife that it was the cat which caused the disaster.

    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.
