i still remember the first day i went to the zoo. when i was only five years old, my mother took me there. i was pleased to see so many real animals at the same time.

　　they seemed so lovely and active. i spent a nice day. but on my way home, i began to feel sorry for them. they were taken away from their parents and friends and also far away from the nature. they must have felt lonely, i thought.

　　every day, the only thing they could do was to sit there and wait for food.
