Everyone has his or her experience that is unforgettable.Mine happened when I was five,when my parents took me to the city zoo.It was a hot summer so most animals were laying down to stay cool.As we walked around,I saw a panther crouching by a hill in its enclosure.All of a sudden,the panther leaped over the wall and jumped on the back of an old lady who was eating a hamburger.The old lady let out a high pitched scream and fell down from her seat,sprawling on the cement pavement and passed out.The panther did not attack the old lady,but picked the hamburger dropped by the lady.After swallowing the hamburger,the panther started walking around the cafeteria with many visitors looking at it.One kid saw the animal outside,and called excitedly,“Mommy!Look!I want to pat the Panther!” The kid ran to the animal.By the time the panther was laying on the ground.The little boy went to the panther and sat on its back.The panther stood,with the boy on its back,started running towards the gate of the zoo and disappeared into the city in the dusk twilight.I took a few pictures of the boy riding the panther,and this,was an experience I will never forget.(224 词)
